Answer:
A. f(-x) = f(x)
Step-by-step explanation:
When plugged into a graph, we can see that the y value of -x is equal to x.
This means, that if we compare the y value of x=3 and x=-3, they will be the same on the graph.
Answer:
C. The two quantities are equal
Step-by-step explanation:
Column A
Substitute the numbers with the letters
an = a1 + (n - 1) d should be an = 2 + (8 - 1) 5
Work it out, you should get 37
Column B
Substitute the numbers with the letters again
an = a1 + (n - 1) d should be an = 13 + (9 - 1) 3
Work it out, your answer should be 37 as well
Tada, done. The answer is C.
I guess it’s gonna be -3/2?
Answer:
see explanation
Step-by-step explanation:
Using the exact values of the trigonometric ratios
sin60° = , cos60° =
sin45° = cos45° =
Using the sine ratio on the right triangle on the left
sin60° = = =
Cross- multiply
2a = 4 × = 12 ( divide both sides by 2 )
a = 6
Using the cosine ratio on the same right triangle
cos60° = = =
Cross- multiply
2c = 4 ( divide both sides by 2 )
c = 2
------------------------------------------------------------------------------------------
Using the sine/cosine ratios on the right triangle on the right
sin45° = = =
Cross- multiply
b = 6
cos45° = = =
Cross- multiply
d = 6 ( divide both sides by )
d = 6
------------------------------------------------------------------------------------------------
a = 6, b = 6, c = 2, d = 6
Answer:
y = 7
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, then
AC = BD , that is
AE + EC = BD [ AE = EC = 6y ]
6y + 6y = 84
12y = 84 ( divide both sides by 12 )
y = 7
