Write the formula for the parabola.
Answer:
Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

m3
Will give brainlest if right
Step-by-step explanation:
Use formula for cube volume:
V=a³
Then add informations you already have and you are done.
V=0,5³
V=0,125 m³
Answer:
0.125
Step-by-step explanation:
The formula to find the volume of a cube is: V=a^3
Since we are given that one side of the cube is 0.5 m, you can take 0.5 and insert it into the formula V=a^3
V=0.5^3
V=0.125

Find the area of a semicircle.
Use a = 3.14
Answer:
157.08cm²
Step-by-step explanation:
pls brainliest
Answer:
157 cm
Explanation:
First you need to find the radius so you divide 20 by 2 (20 ÷ 2). Which will give you, our radius of 10. You take that radius and square it so 10 x 10. You will get a product of 100. Then you multiple the 100 by pi (100 x 3.14) and you will get 314. Since it's a semicircle you need to cut this 314 in half (314 ÷ 2 = 157).

Answer:
1. m∠1 = 105 m∠2 = 75
2. x= 130
Step-by-step explanation:
1. Solved m∠2 by using 75° angle because they are the same angle
m∠1 = 180- 75°
2. 180-70= 110
(x-20)= 110
x= 130

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his stock in Company B was worth $1000. The stock in Company A has increased 20% since last year and the stock in Company B has increased 22%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer:
20.7%
Step-by-step explanation:
Amount of stock increased in Company A = 20% of 1790
= 0.20 * 1790 = $ 358
Investor's stock in company A this year = 1790 + 358 = $ 2148
Amount of stock increased in Company B = 22% of 1000
= 0.22 * 1000= $ 220
Investor's stock in company B this year = 1000 + 220 = $ 1220
Total amount in investor's stock account = 2148 + 1220 = $ 3368
Increased amount = 3368 - 2790 = $ 578
Increase percentage = [tex]\frac{578}{2790}*100[/tex] = 20.71
= 20.7%
Answer:
20.7%

Find the value of the missing angle ``
180

Answer:50
Step-by-step explanation:
a right angle is always 90 degrees and we know triangles add to 180 degrees. So add 90 and 40 to get 130. Then subtract 180 from 130 to get 50.

You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s eyes to be 1 times as far apart as Dan’s eyes. A scale giant would have the same multiple for both.
If Dan's eyes are 5 cm apart, how many centimeters apart should Marcellus's eyes be?
Marcellus's eyes should be 5 cm apart
If Marcellus eyes are 1 times as far apart as Daniels eyes. We can write this mathematically as;
Marcellus eyes are 1x far apart as Dan's eyes.
If we spin this over, we are told that Dan's eyes is 5 cm apart. How far apart would Marcellus's be.
Marcellus eyes will be Dan's eyes divided by the mathematical equivalent we wrote the other time, which is 1 times.
Essentially, Marcellus's eyes will be just as wide as Dan's eyes

(05.01)A scale drawing of a kitchen is shown below. The scale is 1 : 20.
A rectangle is shown. The length of the rectangle is labeled 4 inches. The width of the rectangle is labeled 5 inches.
Show your work to determine the area of the room in square feet.
Answer:
the room will be 80 inches by 100 inches
( 1 inch ----> 20 inches
so 4 inches ----> 80 inches )
or
6 2/3 ft by 8 1/3 ft
The area of the given room is 166 2/3 ft².
What is a scale drawing?A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.
The area of the room can be calculated as;
The length of the room = 20 x 4 = 80 inches
The width of the room = 20 x 5 = 100 inches.
Now, 1 inch = 1/12 foot
80 inches / 12 = 6 2/3 ft
100 / 12 = 8 1/3 ft
The Area = 6 2/3 x 8 1/3
The Area = 25/3 x 20/3
The Area = 500 / 3
The Area = 166 2/3 ft²
Therefore, The area of the given room is 166 2/3 ft².

The denominator has to become 100 in order to find the percentage,,,
,,,or divide the numerator by denominator and then multiply by 100 in order to find the percentage.
I'll do both ways:
since 25 x 4 = 100,
[tex]\frac{9(4)}{25(4)}[/tex] = 36/100 = 36%
OR
9/25 = 0.36
0.36 x 100 = 36%
ANSWER: 36%what the radius and diameter
Answer: 1. The Diameter is 25 and The Radius is 12.5
