Roland hires a mechanic to do some work. He pays y dollars per hour for a 3-hour job plus $48 in replacement parts. The total cost comes to $200. Please round to the nearest cent.

Create an equation that can be used to find the amount, in dollars, the mechanic charges per hour.

Answers

So, the variable here is y: the amount of dollars per hour of work. We already know how many hours (3), the additional costs (48), and the total cost (200). What we need to do is put this into an equation. So we have number of hours times hourly rate plus additional costs:
3y + 48 = 200

In order to solve for y, this is what you have to do:
3y + 48 = 200 (subtract 48 from both sides)
3y = 152 (divide by 3 on both sides)
y = 50.666666
round to the nearest cent and you’d get a final answer of:
50.67

A stunt car drives off a 150m cliff at a speed of 45mph
. How long does it take the stunt car to reach the ground?

Answers

Answer:

5.53 seconds.

Step-by-step explanation:

The equation of motion is

d = 4.9t^2 so

150 = .9 t^2

t^2 = 150 / 4.9

t^2 = 30.612

t = 5.53 seconds.

Which of the following lines is parallel to -5/7x-2

Answers

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. Parallel lines are lines which have the same slope but can have different y-intercepts. So, the equations that would be parallel to the given equation would have a slope of -5/7 and ANY y-intercept.

find the values of a,b,and c

Answers

Answer:

a = 1

b = -6

c = 0

Hope this helps!

Answer:

a = 1

b = -6

c = 0

Step-by-step explanation:

A standard quadratic equation is set up in the form ax^2+bx+c. So, for this equation, "a" is the value before the x^2, which is 1, "b" is the value before the x, which is -6, and since there is no "c" value, that means c is 0.

find x^12 coefficient in the expression of (3x -2/x )^10

Answers

Step-by-step explanation:

(3x-2/x)^10

(r+1)th term = 10Cr (3x)^10-r (-2/x)^r

= 10Cr (3)^10-r (-2)^r (x)^10-2r

Let 10-2r = 12

- 2r = 2

r= - 1

The coefficient of x^12

= 10C-1 (3)^11 (-2)^-1

= 10C11 (3)^12 (-1/2)

= (1/11) (3)^12 (-1/2)

= - 1/22 × (3)^12

Angle A = Angle T

Angle B = Angle U

Angle C = Angle V

Step-by-step explanation:

The order that the angles are listed above shows you which angle in the first triangle corresponds to which angle in the other triangle. It tells you triangle ABC = triangle TUV. Since A and T are both listed first, they are equivalent. Angles B and U are both listed second, so they correspond to each other. And angles C and V are listed last, so they correspond to each other.

Writer the equation of the porabola in vertex form vertex0,3 point 1,-5

Answers

Answer:

the desired equation is y = -8x^2 + 3

Step-by-step explanation:

The vertex form of the equation of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex and (x, y) is another point on the graph of the parabola.

Substitute 1 for x, -5 for y, 0 for h and 3 for k. We obtain:

-5 = a(1 - 0)^2 + 3, or

-5 = a(1) + 3, or -5 = a + 3. Then a must be -5 -3, or a = -8

and the desired equation is y = -8x^2 + 3

assume (-2,0) and (3,0) are the x intercepts of y=f(x). find the x intercepts of g(x)= f(x-3)

Answers

The intercepts of a graph are the points the graph crosses the x-axis

The x-intercepts of [tex]\mathbf{g(x) = f(x - 3)}[/tex] are (-5,0) and (0,0)

For y = f(x), we have

[tex]\mathbf{(x,y) = (-2,0)\ (3,0)}[/tex]

For g(x) = f(x - 3), we have:

[tex]\mathbf{(x-3,y) = (-2-3,0)\ (3-3,0)}[/tex]

[tex]\mathbf{(x-3,y) = (-5,0)\ (0,0)}[/tex]

Recall that:

[tex]\mathbf{g(x) = f(x - 3)}[/tex]

Hence, the x-intercepts of [tex]\mathbf{g(x) = f(x - 3)}[/tex] are (-5,0) and (0,0)

so thus Marcus doesn't stick to his plan because he didn't have the number of kites.

No, Marcus did not stick to his plan.

What is Unit rate?

A unit rate means a rate for one of something.

Given that, Marcus builds 2,744 kites for a 14-day summer kite festival.

He plans to give away about the same number of kites each day.

He gives away 492 kites the first two days,

According to his plan, he should sell = 2744/14 = 196

But he sold = 492/2 = 246 each day

Hence, he sold more kites than his planning, so he did not stick to his plan.
