Answer:
The answer to 28% of 158 is 44.24
From any one vertex, you can draw a line that is perpendicular<span> to the opposite base — that's the </span>altitude<span> to this base. Any </span>triangle<span> has three </span>altitudes<span> and three bases. You can use any one </span>altitude<span>-base pair to </span>find<span> the area of the </span>triangle<span>, via the formula A = (1/2)bh </span>
The formula for exponential growth is y=a(1+r)
. Where a is the initial value when time is 0 (100 in this case). r is the growth rate, we can see that the growth is 10%. And x is how much time has passed, we want to find out how many trucks after 9 years.
So we would plug the values in to get y=100(1+.1)
. Solving this gives us 235.79, so we would round up to 236, and our answer would be 236 trucks registered in the city in year 9.
Edit: The x and the 9 are exponents, the formatting made them look a bit weird.
Answer:
a = - 17
Step-by-step explanation:
5+2a = -29
2a = -29-5
2a = - 34
a = -34/2
a = -17
