Answer:
base = 4 yards, height = 1 5/7 yards
Step-by-step explanation:
The scale factor relating the dimensions of the smaller triangle to the larger is 4/7, the ratio of the lengths of their bases. That same scale factor applies to the height, so the smaller height is ...
... (3 yards) × (4/7) = 12/7 yards = 1 5/7 yards
I'd say it's D, y=6x
I'm 95% sure
You can automatically use proccess of elimination for letter A and C. As for B, I think there was a ruling that you can't divide, if I recall correctly.
130 degrees and 30 minutes
That's minutes as in arc-minutes, a sub-division of a degree. 1 degree is made up of 60 minutes.
So 130°30' is the same as 130° + 30/60° = 130.5°.
Answer:
Step-by-step explanation:
hello :
note :
for all x in ℝ : 1) sin(x+2kπ) = sinx ...k in Z 2) sin(-x) = -sinx
in this exercice :
sin(-4π-x)= sin(-x) = -sinx because : -4π = 2(-2)π (form : 2kπ when : k=-2)
