90+70= 160
Then 180-160=20
So angle A is 20
I think the answer would be -14
Answer:
h(0) = 10
h(4) = 16
Step-by-step explanation:
h(0) = 2(0)² - 3(0) + 10 = 10
h(4) = 2^4 = 16
Answer:
it is B
Step-by-step explanation:
Speed is measured in miles per hour (mph).
<span>The formula Distance equals rate times time (d=rt) can be rearranged and the rate can be solved, </span>
<span>d = r*t => r = d / t . d = 100 miles, time = 6 hours, Rate = 16.66 mph (16 and two thirds). </span>
<span>The same formula can be used for the second part, </span>
<span>21000 / 24 = rate, Rate = 875 kilometers per hour</span>
