First find number of hours h=236/5.90=40 hours..h=40 now see 40 is between 39 and 41 thus 39<h<41 is the inequality

Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.

Luba_88 [7]

Answer:

$S.A = 135.6 yd^2$ (

Step-by-step explanation:

Surface area of cone is given as:

Surface Area (S.A) = πr(r + l)

Where,

$r = radius = 3 yd$

$l = slant height = 11.4 yd$

Take π as 3.14

Plug the given values into the formula to find the surface area.

$S.A = 3.14*3(3 + 11.4)$

$S.A = 9.42(14.4)$

$S.A = 135.6 yd^2$ (rounded to the nearest tenth)

the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation

Arte-miy333 [17]

The exponential equation that models this situation is:

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

$A(t) = A(0)(1 - r)^t$

$A(t) = 18000(1 - 0.15)^t$

$V(t) = 18000(0.85)^t, 0 \leq t \leq 5$ .
