How do i solve this problem? how did they get 2.5?

WARRIOR [948]

Take the GCF (-8t) of the given expression.

You'll get -8t(2t-5).

Now, set each equal to zero and solve for x.

-8t = 0 2t-5=0

t=0 t = 5/2 (Or 2.5 seconds)

Find the tan A and sin B exactly.

Rudik [331]

Answer:

B - tan A = 4/3, sin B = 3/5

Step-by-step explanation:

First, lets find the length of the third side

b = √15² - 12² = √225 - 144 = √81 = 9

Now, lets get Tan A and Sin B

Tan A = 12/9 = 4/3
Sin B = 9/15= 3/5

Correct option is B

Find the distance between the points (13, 20) and (18, 8). 7 11 13

cupoosta [38]

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}$
$d = \sqrt{(18 - 13)^{2} + (8 - 20)^{2}}$
$d = \sqrt{(5)^{2} + (-12)^{2}}$
$d = \sqrt{25 + 144}$
$d = \sqrt{169}$
$d = 13$
