Gnom [1K]

Answer:

see explanation

Step-by-step explanation:

Consider

x² = 64 ( take the square root of both sides )

x = 8 , x = - 8 ← are the critical points

Then for x² > 64

x < - 8 or x > 8

The closing amount of the Dow Jones Industrial Average on the stock market for four days is shown in the table below.

andreev551 [17]

Answer:

Option A. a loss of 93.98 points

Step-by-step explanation:

To solve this question we will calculate the difference (change)in closing amount of Dow Jones on stock market that took place on day to day basis.

From 01/27 to 01/28

Change = 13881.93 - 13895.98 = (-14.05)

From 01/28 to 01/29

Change = 13954.40 - 13881.93 = (+72.42)

From 01/29 to 01/30

Change = 13860.42 - 13954.40 = (-93.98)

Here we can see that change from 01/29 to 01/30 is maximum and it is (-93.98).

Therefore answer will be Option A. a loss of 93.98 points.

Tiffany wants to calculate the volume of her globe. The globe is in the shape of a sphere. She measured the circumference of the

Elis [28]

Answer:

Step-by-step explanation:

We know that the volume of a sphere/globe is given as

V=4 /3πr^3

but the circumference is expressed as

C=2πr

solving for r given that C=24

24=2*3.142r

24=6.284r

r=24/6.284

r=3.8in

put r=3.6 in the expression for volume we have

V=4 /3π(3.8)^3

V=4 /3π(55

V=(220.59*3.142)/3

V=693.12/3

V=231in^3

The volume of the globe is 231in^3

Find the area of the shaded sector. Leave your answer in terms of π.

IgorLugansk [536]

Answer:

16π m2

Step-by-step explanation:

The area of a sector (A) is given by:

$A=\frac{\theta}{360}* \pi r^2$

Where

$\theta$ is the angle of the sector

r is the radius of the circle

<em>We can see that the angle of the sector is 90, and the radius of the circle is 8. Plugging these into the formula, we get:</em>

$A=\frac{90}{360}* \pi (8)^2\\A=\frac{1}{4}* \pi (64)\\A=16 \pi$

The area is 16π m2

1. A circular swimming pool has a diameter of 60 feet, and is surrounded by a concrete sidewalk that is 5 feet wide. What is the

Ivenika [448]

We first calculate the area of the entire pool and the side walk.

Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet

Thus the area of the entire pool and the side walk is obtained as follows:

$Area=\pi r^2 \\ \\ =\pi(35)^2=1,225\pi\ square\ feet$

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.

Thus the area of the pool is given by:

$Area_{pool}=\pi r^2 \\ \\ =\pi(30)^2=900\pi\ square\ feet$

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:

$Area_{side walk}=1,225\pi-900\pi \\ \\ =325\pi=1,021 \ square\ feet.$
