Answer:
90 degree
Step-by-step explanation:
∠ 1 , ∠2 and ∠3 are three interior angles of a triangle so the sum of these three angles are 180°
From the figure, ∠1 is a right angle means m∠1=90°
m∠1+m∠2+m∠3=180°
m∠2+m∠3=180°-m∠1
m∠2+m∠3=180°-90°
m∠2+m∠3=90°
The answer is indeed D. If you check the normal distribution curve you get that within 1 standard diviation its
34%+34%=68%
Within 2 it's 34+34+13.5+13.5= 95%
And within 3 it's 34+34+13.5+13.5+2.5+2.5=100%
9/20=0.45
0.45×100=45
45/100 is the answer
w is william, c is charmaine
w = c + 3
3c + 2w = 76
substitute c + 3 for w
3c +2(c + 3) =76
3c + 2c + 6 = 76, combine the c's and subtract 6 from both sides
5c = 70
c = 14
w = c + 3
so w = 14 + 3
w = 17
Answer:
(0,2)
Step-by-step explanation:
I'm going to assume you meant Which point is ON the graph of f(x) = 2 * 5^x?
In order to do this question, all you need to do is pick any number as x. Lets pick 0 in this case.
f(x) = 2 * 5^x
f(0) = 2*5^0
= 2*1
= 2
So one point on the graph would be (0,2)
Why?
Because remember with functions, the f(x) can be swapped out with y, so when x = 0, y = 2.
