Answer:
Step-by-step explanation:
x = (0.5,0)
y= (0,-3)
slope = 2
Answer:
3
Step-by-step explanation:
first term a= 2
last term tn= 32
common ratio r= -2
number of terms
= tn=ar^n-1
32 = 2*(-2)^n-1
divide both sides by 2
32/2 = 2*(-2)^n-1/2
16 = (-2)^n-1
Then...use 16 in the power of 2
(-2)^4 = (-2)^n-1
The bases (-2), cancels out
so we have: 4 = n-1
collect like terms
4-1 = n
3 = n
n= 3
Answer:
1/5
Step-by-step explanation:
There are 30 contestants. 16 are men, which means 14 are women.
All 14 women wear glasses. Since 20 of the contestants wear glasses, that means there are 6 men who wear glasses.
So the probability that a randomly selected contestant will be a male with glasses is 6/30 or 1/5.
Answer:
m∠A= 110°
Step-by-step explanation:
∠A+∠B=180°
5x+20+9x-92=180°
14x=180+92-20
14x/14=252/14
x=18
m∠A=5x+20
= 5(18)+20
=90+20
m∠A=110
