A, B, then F. I hope that helps you!
Is BC=2.3 one of the options?
For that question, you can use the cosine rule, where;
In this case, we have..
Solving for BC with this will get you 2.250406, rounded off to the tenth is 2.3.
You will need to use the compound growth formula - this is...
final number = starting number * (multiplier ^ number of years)
We can turn the 6% into a multiplier by dividing it by 100 and adding 1 on to it:
6/100 = 0.06
0.06+1 = 1.06
Then we can say that the starting number is 254 and the number of years is X, we can then place this all into the original formula:
Final population = 254 * (1.06 ^ X)
Hope this helps! :)
Answer:
∠ X = 55°, ∠ W = 125°, ∠ Z = 55° are correct
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, thus
∠ W = ∠ Y = 125°
Consecutive angles are supplementary, thus
∠ Z = 180° - ∠ W = 180° - 125° = 55° and
∠ X = ∠ Z = 55° ( opposite angles are congruent )
Answer:
Step-by-step explanation:
slope=(-4-8)/(-2-4)=-12/-6=2
eq. of line is
y-8=2(x-4)
y=2x-8+8
y=2x
