Answer:

Part 1) y=45x+150

Part 2) The total charge is \$1,175

Step-by-step explanation:

Part 1) Write an equation in slope-intercept form to represent the total cost, y, of a project that takes x hours

Let

x ----> the number of hours

y ----> the total cost

we know that

The equation of the in slope intercept form is

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have that the charge of  $45 an hour for a coding projects is equal to the slope m of the linear equation

so

m=45\frac{\$}{hour}

The y-intercept is the value of y when the value of x is equal to zero

In this problem the y-intercept is the total cost when the number of hours is equal to zero (the y-intercept is the start-up fee of $150)

so

b=\$150

The linear equation is

y=45x+150

Part 2) How much does the programmer charge for a coding project that takes 25 hours?

For x=25 hours

substitute in the linear equation and solve for y

y=45(25)+150

y=\$1,175

Solve for A if Ab = ut<br> Solve for c if Kc = 9 a<br> Solve for D if Bd = Ca
pychu [463]

Answer:

Below in bold.

Step-by-step explanation:

Ab = ut

Divide both sides by b

A = ut/b.

The other 2 are solved in a similar way:

Kc = 9a

c = 9a/K

Bd = Ca

d = Ca/B.

alexgriva [62]

Answer:

2z + 33

Step-by-step explanation:

Add like terms like below:

(32 - 4) + (2z + 5) = 28 + 2z + 5

Combine like terms again:

(28 + 5) + 2z = 33 + 2z or 2z + 33

Please help! i don't know what to do, my formulas are not working for me. If anyone could please help i would really appreciate
Burka [1]

Answer:

  • The radius is r = 3 in,
  • The height is h = 4 in

<u>The area of the base:</u>

  • A(b) = πr² = π(3²) = 9π in²

<u>The circumference of the base:</u>

  • C = 2πr = 2π(3) = 6π in

<u>The area of the lateral surface:</u>

  • A(l) = Ch = 6π(4) = 24π in²

<u>The surface area:</u>

  • S = 2A(b) + A(l) = 2*9π + 24π = 42π in²
