Answer:
W
Step-by-step explanation:
The table that will represent a function is the table where every x-value (domain) has exactly one y-value (range).
Table W represents a function because each x-value has exactly only one y-value.
The other tables have two y-values assigned to a one x-value.
Answer:
101
Step-by-step explanation:
According to the Law of Cosines, for any △ABC with side lengths a, b, and c, a2=b2+c2−2bccosA; b2=a2+c2−2accosB; and c2=a2+b2−2abcosC
.
The Law of Cosines can be used because all three side lentghs are known.
Set up the equation for the Law of Cosines:
a2=b2+c2−2bccosA
Substitute the known values into the Law of Cosines:
312=222+182−2(22)(18)cosA
Square the values and multiply:
961=484+324−792cosA
Add:
961=808−792cosA
Subtract 808
from both sides:
153=−792cosA
Divide both sides by −792
:
153−792=cosA
According to this equation m∠A
is equal to the inverse cosine function of −153792
. Write this:
m∠A=cos−1(−153792)
Calculate the value of the inverse cosine −153792
on a calculator:
m∠A≈101°
Therefore, m∠A≈101°
.
The equation we need to do is 1/11 times 7/22 so the answere would be
7/242
Answer:
Option A : 15x² + 62x + 63 is the correct answer.
Step-by-step explanation:
Given measurements of the figure are:
5x + 9 and 3x + 7
We have to find the area. We can find the area by multiplying the two expressions.
Area = (5x+9) * (3x+7)
Area = 5x (3x+7) +9(3x+7)
Area = 15x² + 35x + 27x + 63
Area = 15x² + 62x + 63
Hence,
Option A : 15x² + 62x + 63 is the correct answer.
Answer:
Sammy can make 9 bows.
Step-by-step explanation:
3 feet of Ribbon
1/3 for each bow
1/3 + 1/3 +1/3 = 3/3 or 1 so she can make 3 bows out of one foot of ribbon
so if you repeat this than you should get 9 bows out of three feet of ribbion.
