Answer:

your answers are correct

Step-by-step explanation:

A straight angle measures 180°. It looks like a straight line with the vertex as a marked point on the line.

A right angle is usually marked with a little square in the corner, as in diagrams 2 and 5. Diagram 2 also shows complementary angles, two angles that have a sum of 90°.

Supplementary angles have a sum of 180°, so can form a straight angle as in diagram 1.

An obtuse angle is one that has a measure greater than 90°. (If it is greater than 180°, it is called a reflex angle.)

An acute angle is one that measures less than 90°.

Write the equation of a polynomial of degree 3, with zeros 1, 2 and -1 where f(0)=2

ser-zykov [4K]

Answer:

f(x) = x^3 - 2x^2 - x + 2

Step-by-step explanation:

since the zeroes are 1,-1, and 2. we can write the function like

f(x) = (x-1)(x+1)(x-2)

f(x) = (x^2-1)(x-2)

f(x) = x^3 -2x^2 -x +2

and it is true that f(0)=2

X^2 -50x+456=0 solve this algebraiclly find x

bagirrra123 [75]

Answer:

$x=-406$

Step-by-step explanation:

$x^2-50x+456=0$

$x^2-50x=-456$

This is because we subtract 456 from each side.

$x-50=-456$

We then divide the whole equation by x .

$x=-406$

Adding 50 to both sides gives us x by itself, hope this helps :D

choli [55]

Answer:

The length is 12 inches.

Step-by-step explanation:

The volume of a rectangular prism is given by:

V=LBH

It was given that; the rectangular prism has a volume of 600 cubic inches.

The height of the prism is 5 inches and the width is 10 inches.

We want to find the length of the rectangular prism.

We substitute V=600, H=5,and W=10 into the formula:

600=5×10×L

600=20L

$L = \frac{600}{50}$

$L = 12in$
