Once you get to "5" you start rounding up, so the least would be 250.
What is your actual question? Please actually ask a question.
the equation is,
a_n = a_(n–1) + 3 * n + 2
Substituting the values
for day 4, <span>
<span>20 + 3*4 + 2 = 34<span>
Thus the equation is correct</span></span></span>
Therefore to calculate
for a_n at n = 7 or a_7, we must calculate a_5 and a_6 first.
a_5 = 34 + 3*5 + 2 = 51
a_6 = 51 + 3*6 + 2 = 71
Hence,
a_7 = 71 + 3*7 + 2 = 94
Answer: D. 94
Answer:
4.7 yd
Step-by-step explanation:
The horizontal lines in the diagram are parallel, so the angle of depression at D and the angle of elevation at F are congruent. So, you have a right triangle with the measure of one acute angle (F) and the length of the adjacent side (EF = 10 yd). You are being asked to find the opposite side (DE).
The mnemonic SOH CAH TOA reminds you of the necessary relation:
Tan = Opposite/Adjacent
Filling in the given information, you have ...
tan(25°) = DE/(10 yd)
Multiplying by 10 yd gives ...
(10 yd)tan(25°) = DE ≈ 4.663 yd ≈ 4.7 yd
What is
Well, exponents are the amount of times the base number multiplies by itself
So
is 30×30×30=27,000
Answer: 27,000
