Find the radius of the sphere with the given volume. (15 points)
Please show your work!

Answers

Answer:

r = 1/2

Step-by-step explanation:

sphere volume = 4/3πr³

4/3πr³ = 1/6π

divide both sides of the equation by π:

4/3r³ = 1/6

multiply both sides by 6:

24/3r³ = 1

reduce:

8r³ = 1

divide both sides by 8:

r³ = 1/8

r = 1/2

Step-by-step explanation:

Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points

Slope = (4-0)/(0-(-2) = 4/2 = 2

y intercept is where the line intercepts the y axis: it happens in (0;4)

In 2016 the U.S. Census Bureau estimated the population of the United States at 322 million. If the annual rate of growth was about 0.81%, find the expected population at the time of the 2030 census. Round your answer to the nearest ten million.

Answers

Answer:

388,000,000

Step-by-step explanation:

So as we have 322 million

we want to take 0.81% of it and add to the total each year so

322,000,000*0.81%=2,608,200

322,000,000+2,608,200=324,608,200

and now do that for 22 more years so

We get 387,649,305.98 as our population

387,649,305.98 -------> 388,000,000

A deli clerk has lunchmeat formed in the shape of a cylinder with a radius of 2 inches and a height of 4 inches. He divides the lunchmeat into two equal sections by making a vertical cut as shown below. What is the shape of the cross section formed by the vertical cut?

Answers

Answer:

The shape of the cross-section is a square

Step-by-step explanation:

Given

[tex]r =2[/tex]

[tex]h = 4[/tex]

See attachment

Required

The shape of the cross-section

From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.

The dimension of the shape is: the height of the cylinder and the diameter of the base circle

From the given parameters, we have the radius and the height to be:

[tex]r =2[/tex]

[tex]h = 4[/tex]

The diameter (d) is:

[tex]d = 2 * r[/tex]

[tex]d = 2 * 2[/tex]

[tex]d = 4[/tex]

So, the dimension is:

[tex]h = 4[/tex] and [tex]d = 4[/tex]

Since the height and the diameter have the same lengths, then the shape is a square.

Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg

Answers

Answer: C

Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

What is the ratio?

The utilization of two or more additional numbers that compares is known as the ratio.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.

Let 'x' be the weight of Anne's cat. Then the equation is given as,

5 / 7 = 20 / x

Simplify the equation, then we have

5 / 7 = 20 / x

1 / 7 = 4 / x

x = 28 kg

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i

Answers

Answer: B) 4 - 7i

==========================================================

Explanation:

When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.

In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.

In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.

If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.
