What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

Given data; ladder = 18 ft

The base  = 5 ft

In order to find out the height of house.

we know this is triangle shape so we apply here so we consider here x is ladder and y is base and z is height

By pythagoras theorem;

z² + y² = x²

z² = x² -y²

Then put value

z² = 18² - 5²

z² = 299

z = 17.29

z = 17

PLEASE HELP WITH THIS QUESTION!!

Answers

Answer:

x = 8

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] absinC

where a and b are 2 sides of the triangle and C the angle between them

here a = 13 , b = x , C = 30° and A = 26 , then

[tex]\frac{1}{2}[/tex] × 13 × x × sin30° = 26 ( multiply both sides by 2 to clear the fraction )

13x × sin30° = 52 ( using the exact value of sin30° = [tex]\frac{1}{2}[/tex] )

13x × [tex]\frac{1}{2}[/tex] = 52 ( multiply both sides by 2 to clear the fraction )

13x = 104 ( divide both sides by 13 )

If you get an identity when trying to solve a system of two linear equations, the system's graph
must be
a) two parallel lines
b) two lines that are the same
c) two intersecting lines
d) two perpendicular lines
e) None of the above

Answers

Answer:

a) two parallel lines

Step-by-step explanation:

Two parallel lines have the same slope

Let's take a concrete example:
y = 2x + 4        (slope =2, y-intercept = 4)
y = 2x + 10      (slope = 2, y-intercept = 10)

Lines are parallel to each other

If you try to solve this equation you get

2x + 4 = 2x + 10

Subtracting 2x on both sides gives you  the identity 4 = 10 (a contradiction)

This means the 2 line equations are inconsistent


a₁ is the first term of a sequence, r is a common ratio, and d is a common difference. Write the first five terms. a₁ =19, d=-4

Answers

The first five terms of an arithmetic sequence with first term 19 and common difference -4 are 19, 15, 11, 7, 3

The given parameters:

a₁ = 19, d = -4

d is the common difference, hence, the given sequence is an arithmetic sequence.

In an arithmetic sequence, the formula for the nth term is given by:

      a(n) = a(1) + (n - 1) . d

We can also find the terms using recursive formula. The nth term of an arithmetic sequence is equal to the (n-1)th term plus the common difference, d. Mathematically,

      a(n) = a(n -1) + d

Let us start from n = 1

a(1) = 19  (given)

a(2) = a(1) + d = 19 + (-4) = 15

a(3) = a(2) + d = 15 + (-4) = 11

a(4) = a(3) + d = 11 + (-4) = 7

a(5) = a(4) + d = 7 + (-4) = 3

Thus, the first five terms are 19, 15, 11, 7, 3

We can check whether the given point F,Q and P are coplanar by first forming vectors of the each given point. The vector form for general point (a,b,c) can be written as [tex]a\hat{i}+b\hat{j}+c\hat{k}[/tex].

The vector forms of point F,Q and P can be given as 'f', 'q' and 'p'. The scalar triple product of the vectors 'f', 'q' and 'p' can be found out by finding the scalar product of vector 'f' with the cross product of the vectors 'q' and 'p' .

For the points F,Q and P to be coplanar the triple scalar product must be zero else the points are not coplanar.

Between 11 P.M. and 8:20 A.M.​, the water level in a swimming pool decreased by 4/9 in . Assuming that the water level decreased at a constant​ rate, how much did the water level drop each​ hour?

Answers

That means that each hour it drops about 0.0625 inches

Divide the decrease in water level by the length of the time interval.

decrease = 7/12 inches ≅ 0.583 inches

Time interval: From 11 pm to 8:20 am you have 9:20 hours = (9 + 20/60) hours ≅ 9.33 hours

So the water drops at a rate of about

0.583/9.33 inches/hour ≅ 0.0625 inches/hour

Therefore, each hour it drops about 0.0625 inches.

The rate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical reaction and the concentrations of the reacting substances.The rate constant is a proportionality factor in the rate law of chemical kinetics that relates the molar concentration of reactants to reaction rate.

How to determine an equation of the line parallel to another line

In this question we must derive the equation of the line for a given street and look for another equation of the line parallel to the previous one. Lines are first order polynomials of the form y = m · x + b, where m and b are the slope and the y-intercept, respectively.

Now we present the procedure in detail. First, find the equation of the first line:

ALGEBRA The measure of the larger acute angle in a right triangle is two degrees less than three times the measure of the smaller acute angle. Find the measure of each angle.

Answers

The measure of each angle is 23 degrees, 67 degrees, and 90 degrees.

What is Acute angle ?

The acute angle can be defined as the angle  less than 90°. Or we can say that the angle which is between 0° and 90° is called as an acute angle of a triangle.

What is a Right triangle ?

Right triangle is also known as right angled triangle. If a triangle has atleast one 90° angle then the triangle is said to be a right angled triangle. A right angle triangle always follows the Pythagoras theorem.

Now, According to statement given :

Let  smaller acute angle = x,

and measure of larger acute angle = 3x-2

Since, it is right triangle the acute angles must be complementary

x + (3x-2) = 90

4x - 2 = 90

4x = 92

x = 23

i.e. smaller acute angle is 23

now second angle = 3x-2 = 3(23) - 2 = 67

and third angle is 90 , as this is a right angled triangle.

Thus, The measurement of each angle is 23 degrees, 67 degrees, and 90 degrees.

Im confused on the rug question. If you can when you give me the answer can you explain it also?

Answers

I think it's trying to get you to find the side length of the square by using a square root on the area.

Assuming that's the case;

Remember that a square has equal side lengths all around, otherwise it would just be a rectangle. You can actually take the square root of a square to get the side length (hence the name square root). A square root is what number you must multiply by itself to get the root, so for example the square root of 25 is 5 because you can multiply 5 by 5 to get 25. The square root of 100 is 10, because you can multiply 10 by itself to get 100. So you would write this as [tex]\sqrt{100}[/tex], which simplifies down to 10.

An unlimited number of acute triangles can be formed from two sides without an angle measurement, such as a = 10 m and b = 10 m.

As an illustration -

If our side lengths are 10m and 10m, and our angle value goes from 0 to 90 degrees, how many different acute triangles can we create?

Construct a triangle with sides of 10 and 10 metres, an angle of 45 degrees, and a third side that can be extended to the desired length. You have built a triangle.

By changing the third side's length and angle, we can make a whole different triangle that is identical to this one.

Never forget to choose the side lengths and angles. There is a suggestion that you might decide to take a different step. The same angles can be used to make an unlimited number of different triangles.

As a result, with a single angle and a single side length, we can create an endless number of triangles.

y+2=-2(x-1) is in point-slope form, it is neither in slope-intercept form nor standard form.

What is a slope of line?

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope.

We know that  point-slope form = y₂ - y₁ = m(x₂ - x₁)

The endpoints of AB are -16 and -4. Find the coordinate of the point P that partitions the segment in
the ratio 2 : 1.
The coordinate of point P is

Answers

The coordinate of point P is -8.

We are given that the endpoints of AB are -16 and -4.

This means that A is at -16 and B is at -4

Therefore, the total length of the line AB will be-

-16 - (-4) = -12 units

But since length cannot be negative, we take only the absolute value, the length of AB comes out to be 12 units.

Now, point P divides AB in the ratio 2:1

The length of these two parts will be

12 × 2/3 and 12 x 1/3

= 8 units and 4 units

This means that AP = 8 units and PB = 4 units

Hence the coordinate of P will be (-16 + 8) or (-4 - 4)

Thus, the coordinate of point P is -8.

- (x² + x + 1/4) - 15/4 = 0

- (x+1/2)^2 - 15/4 = 0

- (x+1/2)^2 = 15/4

(x+1/2)^2 = -15/4 ==> x has no solutions, y has no solutions

any number to an even power, in this case to the power of 2, has to be positive, but -15/4 is negative.

Write an equation of a parabola with vertex at the origin and the given focus.
focus at (0,7)

Answers

   The equation that defines the parabola with vertex at the point (0, 0) and focus at (0, 7) is:

y = x²/28

What is known as a parabola?

  A parabola is a quadratic function that can move on any axis, it is composed of:

vertexfocal axisdirectrix

   The equation that defines a parabola can be given by:

(x - h)² = 4p(y - k)(y - k)² = 4p(x - h)

  This will depend on its aperture

  In this case we have the vertex of the parabola at the point (0, 0) and the focus at the point (0, 7) this is displaced on the y-axis upward, so the parabola is of the form y = x²


(x - 0)² = 4p(y - 0)

Focus

f = (0, 0  + p)

0 + p = 7p = 0 + 7p= 7

(x- 0)² = 4*7(y - 0)

(x - 0)² = 28(y - 0)

y = x²/28

A circle whose center is at (1, -3) passes through the point (7, 5). whats the radius?

Answers

The distance from the center to any point on the circle exists comprehended as the radius. The radius is 10cm.

What defines the radius of a circle?

The radius of a circle is the separation between any two points on the circle and its center. The radius of a circle is the separation between any two points on its circumference. R or r is typically used to indicate it.

The distance along a line connecting a circle's center to a point on its perimeter is known as a circle's radius. Therefore, the radius is equal to half the diameter's length. Therefore, the radius is equal to half the diameter's length.

The radius of a circle is the separation between any two points on the circle and its center.

In this instance (using the Pythagorean Theorem)

r = [tex]\sqrt{(7-1)^{2}+(5-(-3))^{2} }[/tex]

= √(36 + 64)

r = 10

If a circle whose center is at (1, -3) passes through the point (7, 5) then the radius of the circle exists 10.

Find an explicit relation between x and y in the form f(x,y)=1 by eliminating the parameter

Answers

The explicit relation between x and y in the form is (x2)2+(y2)2=sin2+cos2.

Given that x=2sin, y=2cos, and 0 are constants,

Simplify the parametric functions that are presented. Add their squares after taking them. The following trigonometric identity can be used:

sin2θ+cos2θ=1sin2⁡θ+cos2⁡θ=1

x=2sinθ,

y=2cosθ,0≤θ≤2πsinθ

=x2cosθ,

=y2x

Y=2sin⁡θ,

y=2cos⁡θ,0≤θ≤2πsin⁡θ=x2cos⁡θ=y2

Square them now and add them:

(Using the trigonometric identity sin2+cos2=1)x24+y24=1, where (x2)2+(y2)2=sin2+cos2)

(Using the trigonometric identity sin2+cos2=1)x24+y24=1, where (x2)2+(y2)2=sin2+cos2)

A parameter in a parametric equation can stand in for anything, including an angle. When a parameter is an angle—as opposed to a non-angle parameter—the plane curve can be graphed by choosing values for the angle and computing the x- and y-values.

Hence, the explicit relation between x and y in the form is (x2)2+(y2)2=sin2+cos2.

Find the length of a segment ab but a= -7 and b=9

Answers

The length of a segment ab is 16 units.

Given that, a= -7 and b=9.

We need to find the length of a segment ab.

What is a line segment?

In geometry, a line segment is a part of a straight line that is bounded by two distinct end points and contains every point on the line that is between its endpoints.

The length of the line segment is fixed, which is the distance between two fixed points. The length here can be measured by metric units such as centimetres (cm), millimetres (mm) or by conventional units like feet or inches.

Now, the length of a segment ab=a+b

=7+9=16

Therefore, the length of a segment ab is 16 units.

1
Mode =
Mean =

Answers

The mode of the given data set is equal to 1.The mean of the given data set is equal to 1.80.

What is mode?

A mode can be defined as a statistical term that is used to denote the value that appears most frequently (often) or occurs repeatedly in a given data set. This ultimately implies that, the mode of a data set simply refers to the data point with the highest frequency.

By critically observing the frequencies for the number of TVs shown in the table above, we can logically deduce that the mode is equal to 1.

What is a mean?

A mean can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

How to determine the mean for males?

Mathematically, the mean for this data can be calculated by using the following formula:

Mean = [F(x)]/n

Frequency, n = 3 + 15 + 9 + 11 + 1

Frequency, n = 39.

Total number of TVs = 0(3) + 1(15) + 2(9) + 3(11) + 4(1)

Total number of TVs = 0 + 15 + 18 + 33 + 4

Total number of TVs = 70

Substituting the parameters into the formula, we have;

Mean = 70/39

Mean = 1.80.
