Factor 200t+8t^3-80t^2
valina [46]

Answer:

8t(t - 5)^2

Step-by-step explanation:

I would immediately rearrange these terms in descending order by powers of t:

8t^3 - 80t^2 + 200t

Then I'd factor out 8t:

8t(t^2 - 10 t + 25).

Finally, I'd factor the quadratic t^2 - 10 t + 25:

(t - 5)^2

and so 200t+8t^3-80t^2 in factored form is 8t(t - 5)^2.

A triangle has sides of length 5, 8, and 10. What is the measure of its largest angle?
masha68 [24]
We'll use the Law of Cosines
We'll call
side a = length 5
side b = length 8
side c = length 10
and their corresponding angles as A, B and C
"C" would be the largest angle
cos (C) = (a^2 + b^2 - c^2) / 2 * a * b
cos (C) = (5^2 + 8^2 - 10^2) / 2 * 5 * 8
cos (C) = 25 + 64 -100 / 80
cos (C) = -11 / 80
cos (C) = <span> <span> <span> -0.1375 </span> </span> </span>
arc cosine ( <span> <span> <span> -0.1375 </span> </span> </span> ) = 97.903 Degrees
The largest angle is 97.903 Degrees

Suppose that the function fis defined on the interval (-2,2) as follows. <br>​find f(-1) f(0.5) f(1)
frosja888 [35]

Answer:

Step-by-step explanation:

Hello,

-1 <= -1 < 0

so f(-1)=-1

0 <= 0.5 < 1

so f(0.5)=0

1 <= 1 < 2

so f(1)=1

Thank you.

Question 1
Vikki [24]

Answer:

(B)15,36,39

Step-by-step explanation:

To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.

By Pythagoras Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

In  15,30,35

35^2\neq 15^2+30^2\\1225\neq 1125

In 15,36,39

39^2=36^2+15^2\\1521=1521

In 15, 20, 29

29^2\neq 15^2+20^2\\841\neq 625

In 5,15,30

30^2\neq 15^2+5^2\\900\neq 250

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.

White shapes and black shapes are used in a game some of the shapes are circles all other shapes are sqaures The ratio of the nu
melisa1 [442]

Answer:

The fraction of all the shapes are circles is \frac{9}{32}

Step-by-step explanation:

There are two types of the shapes in a game.

Circle

Square

The ratio of number of white shapes to the number of black shapes is 5 : 11.

Consider there are 50 white shapes and 110 black shapes.

The ratio of the number of white circles to the number of white squares is      3 : 7.

Here 3/10 of the white shapes are circle and 7/10 are white squares.

The number of white circles can be obtained as follows,

White circles = 3/10 × 50

= 50

The number of white squares can be obtained as follows,

White squares = 7/10 × 50

= 35

The number of black circles to the number of black squares is 3/8.

The number of black circles can be obtained as follows,

Black circles = 3/11 × 110

= 30

The number of black squares can be obtained as follows,

Black squares = 8/11 × 110

= 80

The total number of circles is 30 + 15 = 45 and the total number of shapes is 50 + 110 = 160.

The fractions of all the shapes are circles are 45/160 which is simplified to 9/32

The fraction of all the shapes are circles is 9/32
