PLEASE HELPPPPPP<br> The perimeter is 50 ft and the length is 15 ft.<br> What's the width?

SVEN [57.7K]

Answer:

10

Step-by-step explanation:

I assume it's a rectangle, therefore:

P = 50

a = 15 ft

b = ?

P = 2a + 2b

50 = 2 * 15 + 2b

50 = 30 + 2b

2b = 50 - 30

2b = 20

b = 10

An oil tanker breaks apart and starts leaking. As time goes on, the rate at which the oil is leaking out will diminish. Suppose

Alborosie

Answer:

62.77 million gallons

Step-by-step explanation:

Given,

The function that shows rate of leaking oil per minute in after t hours,

$R(t) = \frac{0.7}{1+t^2}$

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,

Hence, the quantity of oil leaked out in the first 3 hours,

$V(t) = \int_{0}^{180} R(t) dt$

$=\int_{0}^{180} \frac{0.7}{1+t^2} dt$

$=0.7 \int_{0}^{180} \frac{dt}{1+t^2}$

$=0.7[tan^{-1}(t)]_{0}^{180}$

$=0.7(tan^{-1}(180) - tan^{-1} (0))$

$=0.7(89.68)$

= 62.77 million gallons

If f(x) = -x + 4 and g(x) = x2 - 5, then f(g(-2)) = ?

schepotkina [342]

Answer:

f(g(- 2)) = 5

Step-by-step explanation:

Evaluate g(- 2) then use this result to evaluate f(x)

g(- 2) = (- 2)² - 5 = 4 - 5 = - 1, then

f(- 1) = - (- 1) + 4 = 1 + 4 = 5
