complete question:

The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass.

A. A= 32π ft²

B. A= 6π ft²

C. A= 36π ft²

D. A= 72π ft²

Answer:

C. A= 36π ft²

Step-by-step explanation:

The image below is where your question emanated. The area of the sector of grass can be calculated below.

Area of a sector = ∅/360 × πr²

where

∅ = angle from the center of the circle

r = radius

Area of a sector = ∅/360 × πr²

r = 12 ft

∅ = 90°

Area of a sector = 90/360 × π × 12²

Area of a sector = 90/360 × π × 144

Area of a sector = 1/4 × 144π

Area of a sector = 144π/4

Area of a sector = 36π ft²

I need help with this plz

Anni [7]

Answer:

exponent of x is 33

exponent of y is 0

Step-by-step explanation:

you need to combine all powers (exponents) of x, and all exponents of y separately.

remember : x to the power of a divided by x to the power of b is x to the power of (a-b).

when multiplying, the "-" turns into a "+".

so, we have actually for x the exponent calculation :

8 - 14 -(-39) = 8 - 14 + 39 = 33

so, x³³ remains.

and for the y exponents

-26 -(-5) -(-21) = -26 + 5 + 21 = 0

so, all the y expressions eliminate each other and y⁰ remains.

Derivative Notation

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$\displaystyle y = \frac{3}{2x^2}$

$\displaystyle \text{Point} \ (1, \frac{3}{2})$

Step 2: Differentiate

[Function] Rewrite [Exponential Rule - Rewrite]: $\displaystyle y = \frac{3}{2}x^{-2}$
Basic Power Rule: $\displaystyle y' = -2 \cdot \frac{3}{2}x^{-2 - 1}$
Simplify: $\displaystyle y' = -3x^{-3}$
Rewrite [Exponential Rule - Rewrite]: $\displaystyle y' = \frac{-3}{x^3}$

Step 3: Solve

Substitute in coordinate [Derivative]: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1^3}$
Evaluate exponents: $\displaystyle y'(1, \frac{3}{2}) = \frac{-3}{1}$
Divide: $\displaystyle y'(1, \frac{3}{2}) = -3$

Lin uses an app to graph the charge on her phone.

exis [7]

Answer:

See below

Step-by-step explanation:

Use the graph to answer the following questions:

When did she start using her phone?

At 2 afternoon

When did she start charging her phone?

At 8 afternoon

While she was using her phone, at what rate was Lin’s phone battery dying?

From 100% to 40% between 2PM and 4 PM:

(100 - 40)/(4 - 2) = 60/2 = 30% per hour
