c. Acute angles are by definition 90 degrees, and acute is less than but not equal to 90 degrees

d. should be always

e. should be never (explanation: they have to be adjacent to be supplementary, and vertical angles are never adjacent)

What is the factorization of 3x2 – 8x + 5?
tatuchka [14]

For this case we must factor the following expression:

3x ^ 2-8x + 5

We rewrite the middle term as a sum of two terms whose product is

a * c = 3 * 5 = 15

And whose sum is

b = -8

These numbers are:

-5 and -3

So:

3x ^ 2-5x-3x + 5

We factor the maximum common denominator of each group:x (3x-5) - (3x-5)

We take common factor(3x-5):

(3x-5) (x-1)

Answer:

(3x-5) (x-1)

JUST HELP ME! PLEASE!!..0o0<br><br>Applying the Pythagorean theorem, solve this triangle.​
Inessa [10]
<h3>Answer:    <u>100 ft</u>  is the hypotenuse</h3>

===================================================

Work Shown:

a = 60 and b = 80 are the two known sides

c  is the unknown hypotenuse

Applying the pythagorean theorem gets us...

a^2 + b^2 = c^2

60^2 + 80^2 = c^2

3600 + 6400 = c^2

10,000 = c^2

c^2 = 10,000

c = sqrt(10,000)

c = 100

A quick way to see that 100 ft is the missing side is to note that a 6,8,10 right triangle scales up to 60,80,100 after multiplying all three sides by 10.

Or you could start with a 3,4,5 right triangle and multiply all three sides by 20.

Algebra 2 Quadratics. <br>Maximum Height of<br> h(t) = -16t + 96t<br>(with steps if possible)
JulijaS [17]

Answer:

max. height = 240

Step-by-step explanation:

Function should be h(t ) = - 16t² + 96t

find the zeros by solving h(t) = 0

- 16t² + 96t = 0 ( take out common factor - 16t )

- 16t(t - 6) = 0

equate each factor to zero and solve for t

- 16t = 0 ⇒ t = 0

t - 6 = 0 ⇒ t = 6

the maximum vertex is at the midpoint of the zeros

t = \frac{0+6}{2} = 3

h(3) = (- 16 × 3) + (96 × 3) = - 48 + 288 = 240 ← max. height
