Answer:

144 ft^2

Step-by-step explanation:

It is the same as the area of a single triangle with a base of 18 ft and a height of 16 ft. The formula is ...

A = (1/2)bh

= (1/2)(18 ft)(16 ft) = 144 ft^2

The shaded area is 144 ft^2.

Answer:

Step-by-step explanation:

Like terms have same variable with same power. Combine like terms

153y³ + 132y² + 6y - 5 - 3y³ - 5y² +4y - 2

= 153y³ - 3y³ + 132y² - 5y² + 6y + 4y -5 - 2

= 150y³ + 127y² + 10y - 7

Let f (x) = -1/2(x + 2)+ 5

bogdanovich [222]

Answer:

Rate of change = -1

Step-by-step explanation:

Given:

f(x) = -½(x + 2)² + 5

Required:

Average rate of change from x = -3 to x = 1

Solution:

Rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

a = -3,

f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5

b = 1,

f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5

Plug in the values into the formula:

Rate of change = $\frac{0.5 - 4.5}{1 - (-3)}$

Rate of change = $\frac{-4}{4}$

Rate of change = -1
