No because it says you can only insert up to 5 Dollar Bills unless you put them in one at a time.

A construction company uses the function f(p) where p is the number of people working on a project to model the amount of money

Jlenok [28]

Answer:

Domain of f(p) = [0,∞), where it belongs to whole numbers only

Step-by-step explanation:

The domain is the set of all possible values of independent variable for which function is defined

As in the given function f(p), we have the independent variable p. As p is the number of people working on the project, so it means either the number of people could be 0 or it could be anything greater than 0, like it could be equal to thousand or ten thousand, but it can not be fraction in any case.

So, the domain is set of whole numbers starting from 0.

Domain of f(p) = [0,∞)

Given g(x)=|-3x+16|, if g(x)=18, find x.

LenaWriter [7]

Answer:

x = - $\frac{2}{3}$ , x = $\frac{34}{3}$

Step-by-step explanation:

The absolute value function always gives a positive value, however, the expression inside can be positive or negative, that is

- 3x + 16 = 18 or -(- 3x + 16) = 18

Solving

- 3x + 16 = 18 ( subtract 16 from both sides )

- 3x = 2 ( divide both sides by - 3 )

x = - $\frac{2}{3}$

or

-(- 3x + 16) = 18

3x - 16 = 18 ( add 16 to both sides )

3x = 34 ( divide both sides by 3 )

x = $\frac{34}{4}$

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

| - 3(- $\frac{2}{3}$ ) + 16 | = | 2 + 16 | = | 18 | = 18 ← True

| - 3( $\frac{34}{3}$ ) + 16 | = | - 34 + 16 | = | - 18 | = 18 ← True

Thus x = - $\frac{2}{3}$ and x = $\frac{34}{3}$ are the solutions

What is the slope of the line described by the equation below?

butalik [34]

Y = -6x + 3
In y = mx + b form, the slope will be in ur m position...

y = mx + b
y = -6x + 3

so ur slope (the number in the m position) is -6

If we know the values of the sine and cosine of x and y, we can find the value of cos(x - y) by using the ____ Formula for Cosin

kolbaska11 [484]

Answer:

$\cos(x - y) = \cos(x)\cos(y) + \sin(x)\sin(y)$

Step-by-step explanation:

Given

$\cos(x - y)$

Required

State the formula

From trigonometry identity, the formula of $\cos(x - y)$ is:

$\cos(x - y) = \cos(x)\cos(y) + \sin(x)\sin(y)$

What does “x” equal ?

crimeas [40]

Answer:

x = 62

Step-by-step explanation:

Since 2 sides are congruent then the triangle is isosceles.

Thus the 2 base angles are congruent.

The sum of the 3 angles = 180°

x = $\frac{180-56}{2}$ = $\frac{124}{2}$ = 62
