Answer: a=√3    b=√6

Step-by-step explanation:

We have a right-angled isosceles triangle

Hence, a=√3

According to the sine theorem :

[tex]\displaystyle\\\frac{b}{sin90^0} =\frac{a}{sin45^0} \\\\\frac{b}{1} =\frac{\sqrt{3} }{\frac{\sqrt{2} }{2} } \\\\b=\frac{2\sqrt{3} }{\sqrt{2} } \\\\b=\frac{2\sqrt{3}(\sqrt{2)} }{\sqrt{2} (\sqrt{2}) } \\\\b=\frac{2\sqrt{6} }{2} \\\\b=\sqrt{6}[/tex]

The slope of the line determined by the equation 2 x+y=5 is -2

A line's inclination or steepness can be determined using the slope formula. Finding the proportion of the change in the y-axis to the change in the x-axis allows it to be used to calculate the slope of any line.

The change in a line's "y" coordinate relative to its "x" coordinate is known as the line's slope.

The given equation =  2x + y = 5

It can be rewritten as: y = -2x + 5            (subtracted 2x from both the sides)

This is the slope-intercept form:  y = mx + c

where m is the slope

If we check our equation, here m = -2

The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.

The measure of < LRQ is 112.5.

The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.

An arc is a segment of a circle's circumference. An intercepted arc is thus one formed when one or two different chords or line segments cut across a circle and meet at a common point known as a vertex.

If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.

So, [tex]$m \angle L R Q=\frac{1}{2}(m \overparen{L N Q})$[/tex]

The sum of the measures of the central angles of a circle with no interior points in common is 360 .

Here, 360 is divided into 8 equal arcs and each arc measures

360/ 8 = 45.

Then, m LNQ = m LM + m MN + m NO + m OP + m PQ = 5(45) = 225.

The difference quotient of f(t) is: (6 - 2h - 4t)

And when h tends to zero is (6 - 4t)

Here we have the function:

f(t) = (2t)(3 - t)

Expanding the function we get:

f(t) = 6t - 2t^2

Now we want to get the difference quotient, which is:

(f(t+h) - f(t))/h

Replacing our function there, we will get:

( 6*(t + h) - 2*(t + h)^2 - 6*t + 2*t^2)/h

Now we can simplify the numerator to get:

(6*t + 6*h - 2t^2 - 2h^2 - 4*t*h - 6t + 2t^2)/h

(6h - 2h^2 - 4th)/h

Now divide by h so we get:

(6 - 2h - 4t)

Now, remember that in the difference quotient we need to take the limit when h tends to zero, in that limit we will get:

Work Shown:

M = number of miles

L = cost to rent a luxury car = 1.15M + 16.40

E = cost to rent an economy car = 0.80M+10.95

C = difference in price

C = L - E

C = (1.15M + 16.40) - (0.80M+10.95)

C = 1.15M + 16.40 - 0.80M-10.95

C = 0.35M + 5.45

Don't forget to distribute the negative to each term in the second parenthesis.

-------------------

Optional Section:

Let's say you drove M = 100 miles as an example.

The luxury car would cost L = 1.15M+16.40 = 1.15*100+16.40 = 131.40 dollars to rent.

The economy car would cost E = 0.80M+10.95 = 0.80*100+10.95 = 90.95 dollars to rent.

The difference in rental costs is L-E = 131.40-90.95 = 40.45 dollars.

Or you could say C = 0.35M+5.45 = 0.35*100+5.45 = 40.45

This means you pay $40.45 more if you go for a luxury car instead of an economy car.

The magnitude of the vector RS is found to be - 6√2.

The direction of the given vector RS is - Ф = 45° in the fourth quadrant clockwise

The algebraic representation of the distances among two points based on their coordinates (in coordinate system). The Pythagorean theorem is used to calculate distances between points in 2- and 3-dimensional Euclidean space using rectangular coordinates.

Now, in response to the question;

The coordinates of points R and S are (-3,3) and (-9,9), respectively.

The distance formula is described as follows for the points R and S:

RS² = (x₂ - x₁)² + (y₂ - y₁)²

RS = √[(x₂ - x₁)² + (y₂ - y₁)²]

R and S's coordinates are-

(x₁,y₁) = (-3,3)  and (x₂,y₂) = (-9,9).

Changing the values with in formula;

RS = √[(-9 + 3)² + (9 - 3)²]

RS = √[(-6)² + (6)²]

RS = √[36 + 36]

RS  = 6√2 (magnitude of the vector RS)

Now, estimate the direction of the vector RS.

A vector's direction is described by the angle it makes with such a horizontal line.

To determine the direction of a vector, use one of the following equations:

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

         = (-9 + 3)/(9 - 3)

tan Ф = -1

Ф = 45° angle of direction in the fourth quadrant clockwise.

As a result, the distance between coordinates R and s is observed to be 6√2, which is same as the magnitude of the given vector RS,

The system of equations that can be used to determine the cost for each pound of jellybeans and almonds is

5x + 3y = 16

2x + 6y = 22

The cost of one pound of jellybeans is $1.25.

The cost of one pound of almonds is $3.25.

Given this two equations:

5x + 3y = 16 equation 1

2x + 6y = 22  equation 2

Take the following steps to determine the required values:

Multiply equation 1 by 2

10x + 6y = 32 equation 3

Subtract equation 2 from equation 3

8x = 10

Divide both sides of the equation by 8: x = 10 / 8

x = 1.25

Substitute for x in equation 1:

5(1.25) + 3y = 16

6.25 + 3y = 16

3y = 16 - 6.25

3y = 9.75

y = 9.75 / 3

The length of A'B' is 2 unit when Line segment AB has a length of 2 units. It is translated 6 units to the right on a coordinate plane.

What is Translation ?

Translation is a rigid transformation in which a figure or a line segment is shifted or moved without changing its shape and size.

That is, if the measurement of segment AB is 2 unit then after translation by any factor its measurement will not change,

So, the measurement of segment A'B' would be 2 unit.

Verification :

Let the coordinates of A and B are (x₁, y₁) and (x₂, y₂) respectively,

Also, the rule of translation 6 unit right is,

(x,y) → (x + 6, y)

By the distance formula,

The measure of segment AB = √(x₂- x₁)² + (y₂ - y₁)²

Thus, if A'B' is the transformed segment of segment AB,

Then, coordinates of A' and B' are (x₁ + 6, y₁) and (x₂ + 6, y₂)

So, the measure of segment A'B' =

√(x₂ + 6 - x₁ - 6)² + (y₂ - y₁)² = √(x₂- x₁)² + (y₂ - y₁)²

Hence, the measure of AB = measure of A'B'.

The combined cost of 2 yards of yellow and 1 yard of purple fabric is  $17.69.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Length of yellow fabric = 5 yards

Length of purple fabric = 8 yards

Let x be the cost of per yard purple fabric.

Then, cost of per yard yellow fabric = 2 + x

Now since, Total amount paid is $62.80

Therefore,

5(2 + x) + 8x = 62.8

expanding the brackets we get,

10 + 5x + 8x = 62.8

Solving we get,

10 + 12x  = 62.8

or, 12x = 52.8

⇒ x = 62.8/12

⇒ x = $5.23

Thus the cost of per yard purple fabric = $5.23

Similarly, cost of per yard yellow fabric = 2 + 5.23 = $7.23

Thus, combined cost of 2 yards of yellow and 1 yard of purple

fabric = 2*$5.23 + $7.23

= $10.46 + $7.23

= $17.69

Thus, the combined cost of 2 yards of yellow and 1 yard of purple fabric is  $17.69

Answer:

x = 12

Step-by-step explanation:

NB. Supplementary angles / Angles of a straight line add up to 180°

180° - 124° (the given angle)

= 56°

This means that the other part of the angle must be equal to 56° ...in other words (4x + 8)° = 56°

(4x + 8)° = 56°

56° - 8°

= 48°

So 4x = 48°

-Divide both sides by 4 in order to get rid of the 4 infront of the x so that you're able to get x alone to solve.

4x ÷4 = 48° ÷4

x = 12

You can substitute 12 in the place of x to see if this is correct.

(4(12) +8)° = 56°

56° + 124° = 180°

....therefore x = 12

We are given that;

Amount of paper clips machine can make in an hour = 300 paper clips

Amount of strings the machine can make in an hour = 360 strings

Now, the machine starts working at 1pm and makes 450 paper clips.

Thus, time taken = 450/360 = 1.25 hours

This is at 2:15 pm

By 6pm, time taken would be 6:00 - 2:15 = 3:45 or 3.75 hours

Outside the circles: In a Venn diagram, an element that is positioned outside every circle does not belong to any of the sets being represented.

D. This is so because these components are a part of the intersection of the two sets and as such, they are a part of both sets.
