Answer:

First you would take 5% of 4000. Add that to 6.5% of 6000. And then add that to 11% 3560(because that's the amount he earns over 10000). You should end up with $981.6

The graph of the function C(x) = −0.34x2 + 12x + 62 is shown. The function models the production cost, C, in thousands of dollar

Virty [35]

Answer:

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Step-by-step explanation:

Let

x ----> is the number of tires produced, in thousands

C(x) ---> the production cost, in thousands of dollars

we have

$C(x)=-0.34x^{2} +12x+62$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

The graph in the attached figure

we know that

Looking at the graph

For the interval [0,1.12) -----> $0\leq x$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

For the interval (34.18,39.87] -----> $34.18 < x\leq 39.87$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

Remember that the variable x (number of tires) cannot be a negative number

therefore

If the company wants to keep its production costs under $75,000 a reasonable domain for the constraint x is

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

A cylinder has a radius of 4 inches and a high of 10.5 inches what is the approximate volume of the cylinder

olga55 [171]

Answer:

V ≈ 527.79

Step-by-step explanation:

Formula is V= πr2h

therefore

V = π * 4 * 2 * 10.5

V = π * 8 * 10.5

V ≈ 527.79

In triangle ABC AB is equals to AB and Angle B equal to 80 find the angle A

insens350 [35]

Answer:

∠A = 20°

Step-by-step explanation:

Given:

Line AB equal to line AC

So, we can say that;

∠B = ∠C

∠B = ∠C = 80°

Using angle sum rule

∠A + ∠B + ∠C = 180°

∠A + 80° + 80° = 180°

∠A = 20°

What is the solution for x in the equation?<br> -x + 3/7 = 2x - 25/7

Pachacha [2.7K]

Answer:

x= 4/3

Step-by-step explanation:

Subtract 3/7 from both sides

-x= 2x-28/7

simplify

-x=2x-4

Subtract 2x from both sides

-3x=4

divide both sides by -3

x= 4/3
