One side of triangle is half the longest side. The third side is

Keith_Richards [23]

Let S be the first side.
Longest side is then 2S.
Third side is 2S-10.
Perimeter is sum of all three sides = S+2S+2S-10 = 75
=>
5S-10=75
5S=75+10=85
S=17

Therefore
S=17 is the first side.
Longest side is then 2S=2*17=34.
Third side is 2S-10=2*17-10=24.

Which of the following could be the third side of an obtuse triangle with the other two side lengths of 6 and 7.

Nataly_w [17]

Pythagorean theorem.
a^2+b^2=c^2
6^2+7^2=c^2
36 + 49 = c^2
85 = c^2
sqrt of 85 = 9.22

So the best answer would be C. 9

The projected population of a certain ethnic group(in millions) can be approximated by p(t)equals=39.07 left parenthesis 1.021

user100 [1]

Answer:

a) p(10) ≈ 48.10
b) about 1.00 million/year

Step-by-step explanation:

a) Use t=10 in the given formula and do the arithmetic.

39.07×1.021^10 ≈ 48.0951 ≈ 48.10 . . . millions

b) The derivative of p(t) is ...

p'(t) = p(t)·ln(1.021) ≈ 0.8120·1.021^t

p'(10) ≈ 0.99954 ≈ 1.00 . . . . millions per year
