QUESTION POSTED AT 20/02/2020 - 11:19 PM

The answer to this question would be:

Jim =6 years

Harry =2 years

To answer this question, you need to translate the description into a mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J

2. (J+2)= 2(H+2)

J+2= 2H+4

J= 2H +2

If you put the 1st and 2nd equation together, the result would be:

H+4= J

H+4= (2H +2)

H-2H= 2-4

-H= -2

H=2

After that insert the H value to either 1st or 2nd equation.

H+4= J

2+4=J

J= 6

Jim =6 years

Harry =2 years

V=πr^2(h/3)

V≈804.25

Since the height is 12, and radius is 8, take the radius and square it. 8 squared equals 64. Now, take the height (12) and divide that by three. This equals 4.

So Volume = Pi times 64 times 4. The answer should be 804.247. Once rounded, you should get 804.25

QUESTION POSTED AT 31/03/2020 - 10:40 AM

Get the area of the circle. Use this formula:

Area = * radius^2

We know the radius is 4 yards.

Area = 3.14 * 4^2

Area = 3.14 * 16

Area = 50.24

Now for the square. Double the radius to get the diameter to get the length of the side.

4 * 2 = 8

Formula for finding the area of a square is

Area = side^2

Area = 8^2

Area = 64

And because we only want to shaded portion, we will subtract the area of the circle from the square.

64 - 50.24 = 13.76

So, D) 13.76 square yards is the answer to this question.

QUESTION POSTED AT 30/03/2020 - 01:33 AM

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :

Current worth = 10,000,000 * (1.03)^years

We must determine the years when current worth = 13,000,000

13,000,000 / 10,000,000 = 1.03^years

1.3 = 1.03^years

Taking logs of both sides:

log (1.3) = years*log(1.03)

log(1.3) / log(1.03) = years

0.11394335231 / 0.012837224705 = years

years = 8.8760113598

Roughly about 8.9 years
