The length of a rectangle is
eight feet more than the width.
The perimeter is 60 feet. Find the
length and width.

Answers

Answer 1

Answer:

11 and 19

Step-by-step explanation:

solution

let,the lenght be (x+8) and width be x.

Now,

The perimeter of rectangle=2(l*w)

or,60=2(x+8*x)

or,60=4x+16

or,60-16=4x

or,44=4x

or,44÷4=x

x=11

breath=11

length=(x+8)

=11+8

=19

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1?

Answers

Answer: y= -1x - 5  

Step-by-step explanation:

The equation has to be in slope-intercept form which uses the formula

y=mx+b   where m is the slope and b is the y-intercept.

So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.

the x coordinate is -7  and the y coordinate  is 2

2 = -1(-7) + b    

2 = 7  + b  

-7   -7

b = -5  the y intercept is -5

Now the equation will be y= -1x - 5

|x| = 2

Answers

Answer:

Step-by-step explanation:

From the picture attached,

Function given is a parabola, therefore, function is a quadratic function.

Domain of the function : x-values(input values) on the graph

                                      : -∞ ≤ x < ∞

Domain in set notation : {x | x ∈ All real numbers}

Domain in the form interval notation : (-∞, ∞)

End behavior of the function : As both the ends of the function are downwards towards the infinity,

                                                : As x → ∞, y → -∞ [Right end]

                                                : As x → -∞, y → -∞ [Left end]

If the radius of circle A is 2 inches, the radius of circle B is 3 1/4 and the radius of circle C is 1 inch, what is the perimeter of ABC?

Answers

Answer:

39.26 in

Step-by-step explanation:

This problem, bothers on the mensuration of flat shapes.

we know that the perimeter of a circle is the same as the cirmcumference

we also know that the circumference is given as

C= 2πr

For circle A

C=2*3.124*2

C= 12.56 in

For circle B

C=2*3.124* 3 1/4

C= 2*3.142*13/4

C= 2*3.142*3.25

C= 20.42 in

For circle C

C=2*3.124*1

C= 6.284 in

Now the perimeter of all the circles ABC is

=12.56 +20.42 + 6.284

=39.26 in

Find k so that the distance from (–3, –1) to (k, 5) is 10 units.

Answers

Answer:

k = - 11, 5

Step-by-step explanation:

By distance formula:

[tex] \sqrt{ \{ {k - ( - 3) \}}^{2} + \{5 - ( - 1) \}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(5 + 1)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + {(6)}^{2} } = 10 \\ \\ \sqrt{ {(k + 3)}^{2} + 36 } = 10 \\ \\ (k + 3)^{2} + 36 = {10}^{2} \\ ..(squaring \: both \: sides) \\ {k}^{2} + 6k + 9 + 36 = 100 \\ {k}^{2} + 6k + 45 - 100 = 0 \\ {k}^{2} + 6k - 55 = 0 \\ {k}^{2} + 11k - 5k - 55 = 0 \\ k(k + 11) - 5(k + 11) = 0 \\ (k + 11)(k - 5) = 0 \\ k + 11 = 0 \: or \: k - 5 = 0 \\ k = - 11 \: or \: k = 5 \\ \\ \huge \red { \boxed{k = \{ - 11, \: 5\}}}[/tex]

There are two solutions for [tex]k[/tex]: 5 and -11.

In this case, we must use the Length Equation for Line Segment to solve for [tex]k[/tex], whose formula is described below:

[tex]l = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex] (1)

Where:

[tex](x_{A}, y_{A})[/tex] - Coordinates of the initial endpoint.

[tex](x_{B}, y_{B})[/tex] - Coordinates of the final endpoint.

[tex]l[/tex] - Length of the line segment.

If we know that [tex](x_{A}, y_{A}) = (-3, -1)[/tex], [tex](x_{B}, y_{B}) = (k, 5)[/tex] and [tex]l = 10[/tex], then the equation is expanded into this form:

[tex](k+3)^{2}+[5-(-1)]^{2} = 100[/tex]

[tex]k^{2}+6\cdot k + 9 + 36 = 100[/tex]

[tex]k^{2} + 6\cdot k -55 = 0[/tex]

The roots of this Second Order Polynomial are determined by Quadratic Formula:

[tex]k = 5[/tex] or [tex]k = -11[/tex].

There are two solutions for [tex]k[/tex]: 5 and -11.

Answers

Answer:

Normally Distributed.

Explanation:

After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" not an answer. "correlated with a second set of data" is also wrong since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.

A flagpole has a height of 25 meters. There are approximately 3.3 feet in 1 meter.
How tall is the flagpole, in feet, rounded to the nearest tenth?

Answers

Answer:

Step-by-step explanation:53

The height of the flagpole is 82.5 feet.

What is unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that a flagpole has a height of 25 meters.

We know that there is 3.3 feet in 1 meter.

1 meter=3.3 feet.

Now we have to find the height in feet.

So we have to multiply twenty five with three point three

25×3.3=82.5 feet

25 meters=82.5 feet.

Hence, a flagpole has a height of 82.5 feet.
