Answers

Answer:

–59

Step-by-step explanation:

f(x) = -2x - 7

f(x) = -2(-4x + 6) - 7

f(x) = 8x - 12- 7

f(x) = 8x - 19

f(x) = 8(-5) - 19

f(x) = -40 - 19

f(x) = - 59

c) at the point (3,-2)

d) crossing the y-axis at -2 and 3

e) at the vertex of the parabola

Answers

Answer:

Answer b) : crossing the x-axis at -2 and 3

Step-by-step explanation:

The roots will be located at the crossing of the graph with the x-axis at the points (-2, 0) and (3, 0).

Therefore, the correct answer is that labeled b)

The table shows the average bill totals for given numbers of diners at Simone's restaurant. If the rate is constant and you graph this relationship with the number of people along the x-axis and bill amounts along the y-axis, which points will lie on the line you get?

a. (12, 470)
b. (20, 800)
c. (24, 1,020)
d. (27, 1,080)
e. (28, 1,110)

Answers

Answer: B and D

Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080

The point (20 , 800) and ( 27 , 1080 )lies on the line.

Option (b) and (d) is correct.

It is given that average bill totals for given numbers of diners at Simone's restaurant.

To find which points will lie on the line you get.

What is co-ordinate?

Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ).

The rate is constant.

Graph this relationship with the number of people along the x-axis and bill amounts along the y axis.

y = mx + c

=> 40 =m+ c

80 = 2m + c

=> m = 40

40 = 40 + c

=> c = 0

Hence

y = 40x

x = 12 => y = 480

x = 20 => y = 800

x =24 => y = 960

x = 27 => y = 1080

x = 28 => y = 1120

Hence (20 , 800) and ( 27 , 1080 ) point lies on the line

What is m ZSRW?

- 18
- 54
- 126
- 108

Answers

Answer:

126

Step-by-step explanation:

Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.

Finding angles in function of X:

Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So

[tex]3x = 2x + 18[/tex]

[tex]x = 18[/tex]

[tex]3x = 3(18) = 54[/tex]

Angle SRW:

Supplementary with 54. So

54 + SRW = 180

SRW = 180 - 54 = 126

So 126 is the answer.

Which of the following is equivalent to tan(5n/6) PLEASE HELP I GIVE EXTRA POINTS AND BRAINLY

Answers

Answer:

cot 5^/6

Step-by-step explanation:

The equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship

Tan of a function

The tan of a function is determined from the ratio of sine of the angle to the ratio of cosine of the angle.

tanθ = sinθ/cosθ

Cot of a function

This is known as cotangent, which is reciprocal of a tangent.

Cotθ = 1/tanθ = cosθ/sinθ

Thus, the equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship

A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign-in square inches?

Answers

Answer: The answer is 530.66

Step-by-step explanation:

I took the test and 81.64 is wrong, It's 530.66

The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².

What is the area of a circle?

The area of the circle is pi times the square of the radius of a given circle.

The area of the circle = [tex]\pi r^2[/tex]

A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.

The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.

Now, the area of the circle = [tex]\pi r^2[/tex]

the area of the circle = 3.14 × 13 × 13

= 530.66 in²

Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

The sum of two odd consecutive integers is 88. Find the integers.

Answers

-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)

use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.

(2n + 1) + (2n + 3) = 88

add like terms.

4n + 4 = 88

4n = 84

n = 21

now plugin.

2(21) + 1

42 + 1

= 43 (the first odd integer)

this means the second one would be 45.

answer: 43 and 45

add them to check:

43 + 45 = 88
