Answer:Let P = initial investment

     r = annual interest rate (decimal form)

     t = number of years

   A(t) = amount after t years

 

Then, A(t) = Pert

 

A(12.5) = 800e(0.0265)(12.5)

 

             = 800e0.33125

 

             = $1114.17

What is the solution to the inequality 7<=-3x-4
kipiarov [429]

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality 7 \leq  -3x-4

Solving:

Step 1: Switching sides of inequality and reversing the inequality

-3x-4\geq 7

Step 2: Adding 4 on both sides

-3x-4+4\geq 7+4\\-3x\geq 11

Step 3: Dividing both sides by -3 and reversing the inequality

\frac{-3x}{-3}\leq \frac{11}{-3}  \\x\leq -3.6\\

The nearest option is -3 (negative 3)

So, Option B is correct.

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If
Nataly [62]

Answer:

The function is missing in the question. The function is $ C(x) = 0.8x^2 -544x +97410 $

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$ C(x) = 0.8x^2 -544x +97410 $

Cost will be minimum when

x = -(-544)/ 2 x 0.8

  = 340

Therefore, minimum cost for unit car is

$ C(x) = 0.8x^2 -544x +97410 $

$ = 0.8(340)^2 -544(340) +97410 $

=  4930
