68% if you take 31 and divide it by 45 you’ll get .68 which you then turn into a percentage
Answer:
The measure of angle 6 is 72.
The measure of angle 7 is 108.
Step-by-step explanation:
Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.
If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.
The points shown on the graph are (-1,2) and (1,-2).
d = sqrt{-2-2)^2 + (1-(-1))^2}
d = sqrt{(-4)^2 + (1+1)^2}
d = sqrt{16 + 4}
d = sqrt{20}
d = 4•sqrt{5}
d is about 8.94427191.
Rounded to the nearest tenth, we get d = 8.9.
3x/2 units to the right, so b).
It's not c) or d), because the -3x/2 is within the sin, rather than outside like y=sin(x)-3x/2
If it were shifted to the left, the equation would be y=sin(x+3x/2)
Answer:
The required amount is $94.23.
Step-by-step explanation:
It is given that Nolan began a savings account three years ago and the value of his account after x years is
Anias started an account today and the value of her account is
We have to find the amount of money that would she have had to invest to have the same amount of money she has now.
Let the required amount be P.
If Anias started saving x amount in the savings account three years ago, then today the value of her account is
The current value is 100.
Divide both sides by 0.0612.
Therefore the required amount is $94.23.
