Step 2: Solve for x

Answer:

1) a2 = h2 + x2

✔ Pythagorean theorem

2) h2 = a2 - x2

✔ Rearrange the previous statement

3) c2 = h2 + (b-x)2

✔ Pythagorean theorem

4) c2 = h2 + b2 -2bx + x2

✔ Expand (b – x)2

Step-by-step explanation:

The Pythagorean Theorem could be represented mathematically as follows, Here, c represents the length of the hypotenuse (the longest side), or b or a are the lengths of the other 2 sides. From the equation, you can easily find the value of the 1 side if you have the values of the other 2

1) a2 = h2 + x2

Pythagorean theorem

2) h2 = a2 - x2

Rearrange the previous statement

3) c2 = h2 + (b-x)2

Pythagorean theorem

4) c2 = h2 + b2 -2bx + x2

Expand (b – x)2

Answer:

[tex]a_{64} = -313[/tex]

Step-by-step explanation:[tex]a_{64} = 2 -135[/tex]

This is the Arithmetic Sequence Formula->  [tex]a_{n} = a_{1} + (n+1) d[/tex]

1) The d represents your difference of the equation. You can find it by finding a pattern between the three numbers given, which is -5

2) Now that we've found our difference, we can plug it into this lovely sequence we have [tex]a_{64} = a_{1} + (64-1) -5[/tex] (by the way, your n represents your term that you plug into the equation)

3) [tex]a_{64} = 2 + (64-1) -5[/tex]  This also means that [tex]a_{1}[/tex] is our first term, which is 2

4) Simplify [tex]a_{64} = 2 + (63) -5[/tex] --> [tex]a_{64} = 2 +-315[/tex]

5) [tex]a_{64} = -313[/tex]

The formula is confusing at first, but it becomes easier once your learn the patterns!

Part A:

lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.

Part B:

lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph

Part C:

The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.

The Graphs Are Shown Below.

Explanation: 120 % = 1.2

If Maxine is correct, then she spent  1.2

times the hours she did homework than last week.

15 ⋅ 1.2 = 18.0 = 18

15 hours ⋅ 1.2 = 18.0 hours = 18 hours

This means that Maxine is correct.

Answer:

[tex]A=0.0192[/tex]

Step-by-step explanation:

Diameter labeled twelve centimetres D =12cm => 0.12

height labeled thirty-two centimetres H= 32cm => 0.32

Generally the vertical cross section of this cone is a triangle

Mathematically solving

Area of vertical cross section through the center of the base of the cone is given by [tex]A=1/2 D*height[/tex]

[tex]A=R*H[/tex]

Therefore

[tex]A=\frac{0.12}{2} *0.32[/tex]

[tex]A=0.06 *0.32[/tex]

[tex]A=0.0192[/tex]

Step-by-step explanation:

I think it's the right answer not 100% sure

Answer:

:)

Step-by-step explanation:

pretty sure the other guy got it right but to divided you have to do..... for example:

5/8 divided by 1 1/3

1 1/3 can be turned into 3/4.....                5/8 times 4/3

5 times 3 and 8 times 4 which equals 15/32

Answer:

I believe that B is the correct answer!

Step-by-step explanation:

The (x+5) can cancel

Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.

Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)

Lastly the (x-5) on the top and bottom will cancel resulting in result B

I hope this helped!

Answer:

B(lol the one you chose randomly was right)

5, sorry I dunno the second number...

Step-by-step explanation:

(x+5)(x+5)(x-5)/ (x+5)^2(x-5)^2

(x+5)^2 gets canceled out

(x-5)/(x-5)^2

1/x-5

Answer:

A circle is a shape.

Step-by-step explanation:

In geometry circles are known for you to solve the radius wit the formula      A= π r^2

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.
