Answer:

  a)  f(t) = 8000(1.015^t)

Step-by-step explanation:

The growth factor is 1 more than the growth rate. Here, the growth rate is 1.5%, so the growth factor is 1 + 0.015 = 1.015. This is the base of the exponential term. Each year that passes causes the balance to be multiplied by this factor, so the exponent is the number of passing years.

  f(t) = 8000(1.015^t)

What is the surface area of the storage chest? Round your answer to the nearest tenth.
Firdavs [7]

Answer:

<u>1093.5 square inches</u>

Step-by-step explanation:

Surface Area of the storage chest :

⇒ <u><em>2 (LW + WH + LH</em></u>)

  • L = length
  • W = width
  • H = height

=============================================================

Given :

⇒ L = 26 in.

⇒ W = 7.5 in.

⇒ H = 10.5 in.

===========================================================

Solving :

⇒ Surface Area = 2(26 × 7.5 + 7.5 × 10.5 + 26 × 10.5)

⇒ Surface Area = 2(195 + 78.75 + 273)

⇒ Surface Area = 2(546.75)

⇒ Surface Area = <u>1093.5 square inches</u>

Since all terms are a multiple of 4, it can be convenient to start by dividing the equation by 4.

  -16 < 2 + x - 3

  -15 < x . . . . . . add 1 to both sides, collect terms

f-12=2(b-12)
f=2+b
2+b-12=2(b-12)
b-10=2b-24
minus b both sides
-10=b-24
add24
14=b

14-12=2
2+2=4
