507 i think. you just square 13 then multiply that by pi which is 3
Answer:
Step-by-step explanation:
The leftmost line segment has a slope of -2 and (-1,-1) is a point on the line.
Equation: y = -2x-3
middle line segment has a slope of 0 and y-intercept of -2.
Equation: y = -2
The rightmost line segment has a slope of 1.5. (5,0) is a point on the line.
y = 1.5(x-5) = 1.5x-7.5
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. Also in
converting units, you must take note of the units given in the problem. If you
don’t, you would get a lot of errors. Length is the measure of distance and can
be best represented by either in SI units or English units. Example of an SI unit is meter, m, and English
unit is feet, ft. You are given 3 inches and 2 feet. You can convert any of the
numbers into a number that would feel comfortable to you. I will take 3 inches.
Note that there are 12 inches in 1 feet. So divide 3 by 12 and you will get ¼ feet.
Then divide 2 feet to ¼ feet and you will get 8.</span>
Answer:
P(x) = x³ - 3x² - 5x + 15
Step-by-step explanation:
∵ The roots of the polynomial are -√5 , √5 , 3
∴ The polynomial has 3 factors:
(x - √5) , (x + √5) , (x - 3)
∴ P(x) = (x - √5)(x + √5)(x - 3)
= (x² + √5x - √5x - 5)(x - 3)
= (x² - 5)(x - 3) = x³ - 3x² - 5x + 15
∴ P(x) = x³ - 3x² - 5x + 15
Answer: 16.97
<u>Step-by-step explanation:</u>
To find the distance from W to X, you can use the distance formula ...or... draw a right triangle using W and X as the vertices and use Pythagorean Theorem to find the hypotenuse. I will solve using the latter.
The y-distance from W to X is 12.
The x-distance from W to X is 12.
hypotenuse² = 12² + 12²
= 144 + 144
= 288
hypotenuse = 
= 16.97
