Answer:

area of circle F = 9 pi

Step-by-step explanation:

An interesting problem, combining geometry and algebra.

It has not been indicated, but it will be assumed that GH is a tangent to the circle F, hence the tangent-secant theorem from point H applies.

Produce HF to point E on the circumference such that EJ forms a diameter of circle F.

By the tangent-secant theorem,

HG^2 = HJ*HE

Substitute given values,

(x+2)^2 = 2*(2*(2x-1)+2)

Expand algebraically

x^2+4x+4 = 2(4x-2+2)

x^2+4x+4 = 8x

x^2-4x+4 = 0

Factor

(x-2)^2 = 0

=>

x=2

Substitute x=2 into radius FG = 2(x)-1 = 3

Therefore area of circle F

= pi r^2

= pi (3)^2

= 9 pi

Answer:

Step-by-step explanation:

h = -6[tex]t^{2}[/tex] +20t + 4

I will use calculus,  maybe that's not how you're supposed to do this

-12t +20 =0

12t = 20

t = 20 /12

t = 1 [tex]\frac{8}{12}[/tex]

t = 1 [tex]\frac{2}{3}[/tex]

there will be a max at  1.6666666666  seconds

-6*[tex]1.6666666666666^{2}[/tex]  + 20 * 1.6666666666  +4

= 16.666666666666 + 33.333333333333 + 4

= - 16[tex]\frac{2}{3}[/tex] + 33 [tex]\frac{1}{3}[/tex] + 4

= 20[tex]\frac{2}{3}[/tex]  feet max height ( not too high,  for a rocket)

time of flight:

0 = -6[tex]t^{2}[/tex] +20t + 4

use quadratic formula to find t

-20 +- sqrt [ [tex]20^{2}[/tex] - 4*(-6)*4 ] / 2*(-6)

-20 +- sqrt [400 + 96 ] / -12

-20 +- sqrt [496 ] / -12

-20 +- 22.27105 / -12

try the negative option 1st

-42.27105 / -12

3.522 seconds.     time of flight

when will the rocket be at 12' ? :

12 = -6[tex]t^{2}[/tex] +20t + 4

0 = -6[tex]t^{2}[/tex] +20t -8

use quadratic formula again to find t

-20 +- sqrt [ [tex]20^{2}[/tex] - 4*(-6)*(-8) ] / 2*(-6)

-20 +- sqrt [ 400 - 192 ] / -12

-20 +- sqrt [208 ] / -12

-20 - 14.4222 / -12

-34.4222 / -12

2.8685 seconds ( on the way down)

and

-20 + 14.4222 / -12

-5.578 / - 12

0.4648  seconds ( on the way up )

Answer:5

Step-by-step explanation:

Answer:

15/100 x 20 = 3

Step-by-step explanation:

15 percent of 20 is 3.

Consider 15 out of 100 since a percent is always considered out of hundred.

15

___ x 20 =

100

First thing is first, we ALWAYS have to find what the percent is of and its of 20 fruits.

So 15/100 x 20 would be your equation

we can simplify

15

___ x 20 ------> 1 =   15

100 -----> 5               ___ x 1 = 3

                                  5

To simplify we can divide by 20 on the denominator and the factor.

Answer:

  $735

Step-by-step explanation:

We assume the cover needs to cover the pool only, not any extra area around the pool.

The cost is given per square foot, so to find the total cost, we need to know how many square feet the cover must cover. The cost will be found by multiplying the cost per square foot by the number of square feet.*

The dimensions of the pool are given as 35 ft by 70 ft. The pool area is the product of these dimensions.

  A = LW

  A = (70 ft)(35 ft) = 2450 ft²

Then the cost is ...

  C = ($0.30/ft²)(2450 ft²) = $735

The cost to buy a pool cover is $735.

__

* This is the same rule you use for any purchase. The total cost is the cost per item multiplied by the number of items. Here, each "item" is 1 square foot of pool cover.

Answer: The equation of the line in slope-intercept form is “y = 4/3x + 4.”

Answer:

15.8

Step-by-step explanation:

Well if you had to round to the nearest tenth then 12.896 would be 12.9 and 2.93 would be 2.9. The reason is if it is below 5 then you would round down if it is more than 5 then round up. Then add the two numbers which are 12.9+2.9=15.8

Hope it helps. Sorry if it does not!

Answer:

Step-by-step explanation:

We can immediately assume that the answer is either the first or third one based off of the second statement. A product is the result of multiplication, and if you see a number and letter together like in the first and third answers, it means they are to be multiplied. For example, 2a = 2 x a. With the first statement, there are 2 terms in all of the equations so that's no help, but the word sum is the result of addition. In which all two terms are added, so . . . also no help. :( Now the last statement. The thing that will conclude all of your questions. A quotient is the result of division, and it's supposed to be between b and 4. As we can see, in the third equation, they subtract b and 4. That's not division! So that leaves us with one answer. The first equation. . .

Answer:

7/2 or 3.5 inches

Step-by-step explanation:

The volume of the rectangle=

length×width×height, so

V=1/2×2×7/2

V=1×7/2

V=7/2 cubic inches

Next, Volume of the cube=

side^3, or side×side×side

V=1/2×1/2×1/2

V=1/8 cubic inches

First question,

To find how many cubes with the side of 1/2 length that fir into the rectangular prism, take:

7/2÷1/8

=7/2×8

=28 cubes. As a result, there are 28 cubes that will fit into the prism

Second question,

The volume of the person is 7/2 cubic inches or 3.5 cubic inches. Hope it help!

Answer:

the answer is [1/5,36/5]

Step-by-step explanation:

A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable

Answer:

x^4 - x^3 + 2x -6

Step-by-step explanation:

(f-g)(x) = x^4-3x^2+5x-7 - ( x^3-3x^2+3x-1 ) = x^4 - 3x^2+5x-7 - x^3 + 3x^2 - 3x + 1  = x^4 - x^3 + 2x -6

Step-by-step explanation:

x^4-3x^2+5x-7 – x^3-3x^2+3x-1

x^4-3x^2+5x-7 – x^3+3x^2-3x+1

x^4-3x^2+3x^2-3x +5x -x^3 -7+1

x^4+2x -x^3 -6

x^4-x^3+2x-6

Answer: 134 people

Step-by-step explanation:

Data: The soccer team needs to raise $5,092

They are hosting a pancake breakfast to do so and are charging $38 to do so

The number of people they need to attend their breakfast for the money to be raised: $x

Step one, make the equation

$38x=$5,092

Reason: Since we know that the number of people(x) times $38 will equal $5,092 so to put it into an equation will make it easier to solve.

Step two, Isolate x by dividing by 38 on both sides

$38x/38=$5,092/38=x=134

Reason: Since you are trying to find the number of people(x) you have to isolate it. the way to do that is by getting rid of the 38 next to it and by dividing, you cancel out the multplication and get rid of the 38. However, since what you do to one side you do to the other, you divide 5,092 by 38 to get the answer of 134.

Answer:

The original fraction is [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Let the numerator by X

Denominator is three more than its numerator i.e X +3

When both the numerator and denominator are increased by one the fraction becomes 1/2

[tex]\frac{X + 1}{X+3+1} = \frac{1}{2} \\\frac{X+1}{X+4} = \frac{1}{2} \\2X + 2 = X+4\\X = 2[/tex]

Thus, numerator = 2

Denominator = X +3 = 2+3 = 5

The original fraction is [tex]\frac{2}{5}[/tex]

Answer:

x = 20

y = 30

Step-by-step explanation:

Answer:

x = 20

y = 30

Step-by-step explanation:

y = 3x - 30

2x + 2y = 100

2x + 2(3x - 30) = 100

2x + 6x - 60 = 100

8x - 60 = 100

8x = 160

x = 20

y = 3(20) - 30

y = 60 - 30

y = 30
