Answer:
(D) 2
Step-by-step explanation:
The scale factor of the enlargement of ΔABC to ΔA'B'C' is given by the ratio of the length of the corresponding sides of ΔA'B'C' and ΔABC
Therefore, we have;
Therefore, the scale factor = 2
The US postal service delivered 7.14 x 1010 pieces of mail in the month of December 7.14 x 1010=7211.4
3.21 x 1010 in the month of January. 3242.1
What is the total mail delivered for these two months?
7211.4
+ 3242.1
__________
10453 .5 TOTAL MAIL
By the factor theorem, if x + 3 is a factor of f(x) = -3x^3 + 6x^2 + 6x + 9, then f(-3) = 0
f(-3) = -3(-3)^3 + 6(-3)^2 + 6(-3) + 9 = -3(-27) + 6(9) - 18 + 9 = 81 + 54 - 9 = 126.
Therefore, x + 3 is not a factor of the given function
Answer:
85°
Step-by-step explanation:
add 125+150=275
a circle is 360
so 275+85=360
