Answer:

Step-by-step explanation: Sit on the couch and think about the answer while eating cheese puffs and watching reruns of Looney Tunes and then jot down the formula of:

IF f(x)= 22+1 THEN f(x) when x=3 is 7

The answers come so quickly when I ask my magic 8 Ball and I said is 7 the answer? It replied Most Likely so it would be B the correct answer!

Sin =9/15 . Find tan 0

ELEN [110]

Answer:

c. 9/12

Step by step explanation.

Given: sin = 9/15

and,

$sin = \frac{opp.}{hyp.}$

$tan = \frac{opp.}{adj.}$

thus, find adj. side

by using Pythagoras theorem

${c }^{2} = {a}^{2} + {b}^{2}$

then,

let adj. side be a^

${a}^{2} = {c}^{2} - {b }^{2} \\ {a}^{2} = {15 }^{2} - {9}^{2} \\ {a}^{2} = 144 \\ a = 12$

thus,

adj. side is 12

then,

tan of the angle = 9/12

#12 with explanation please

4vir4ik [10]

Answer:

30.01 units

Step-by-step explanation:

Given vertices WXYZ:

W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)

Perimeter is the sum of the side length.

Use distance formula to find each side:

WX = $\sqrt{(2+4)^2+(4-5)^2} =\sqrt{37}$ ≈ 6.08
XY = $\sqrt{(3-2)^2+(-4-4)^2} =\sqrt{65}$ ≈ 8.06
YZ = $\sqrt{(-1-3)^2+(-6+4)^2} =\sqrt{20}$ ≈ 4.47
WZ = $\sqrt{(-1+4)^2+(-6-5)^2} =\sqrt{130}$ $\sqrt{(-1+4)^2+(-6-5)^2}=\sqrt{130}$ ≈ 11.40

Find perimeter:

P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
