Answer:

210 ft^2

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh where b is the base and h is the height

Since this is a right triangle  the base is 20 ft and the heigth is 21 ft

A = 1/2 ( 20) * 21

210 ft^2

Item 3
miss Akunina [59]

Answer:

By an online search, i found that the options are:

Option A. A(10)

Option B. A(11)-A(9)

Option C. A(10)/10

Option D. A’(10)

Let´s start by defining the concept of a derivative.

When we have a function f(x), the derivative, f´(x), is a measure of the rate of change of f(x) with respect to the variable x.

Then if A(t) represents the area covered by the oil, A´(t) is the rate of change of this area as a function of t.

Particularly, A´(10), will be the rate of change at t = 10.

Then the correct option is: Option D. A´(10)

when steve woke up. his temperature was 102°F. Two hours later it was 3° lower. what was his temperature then
AlexFokin [52]
The final temperature is the sum of the initial temperature and the change in temperature. The initial temperature is 102°F. The change in temperature is -3°F.

Operation:

Tf = Ti + ΔT = 102°F + (-3°F) = (102 - 3)°F = 99°F
