The answer is B) 4
the two angles adjacent to the exterior angle equal each other so the equation would be 14x+58=27x+6 subtract the 14x from the 27x
58=13x+6 subtract the 6 from 58
52=13x divide 52/13 leaving you with x=4

Which sum or difference identity could be used to prove that sin(pie + q) = -sin q

Paladinen [302]

Answer:

see below

Step-by-step explanation:

sin(π+q) = sin(π)cos(q) + cos(π)sin(q)

sin(π) = 0

cos(π) = -1

therefore

sin(π+q) = 0*cos(q) -sin(q) = -sin(q)

11. The doubling time of a population of plants is 12 years. Assuming that the initial population is 300 and that the rate of in

Anastasy [175]

Answer:

The population will be of 2400 in 36 years.

Step-by-step explanation:

The equation for the population of plants after t years follows the following format:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the initial amount of plants and r is the yearly rate which it increases.

Assuming that the initial population is 300

This means that P(0) = 300.

The doubling time of a population of plants is 12 years.

This means that P(12) = 2*300 = 600.

We use this to find r.

$P(t) = P(0)(1+r)^{t}$

$600 = 300(1+r)^{t}$

$(1+r)^{12} = 2$

$\sqrt[12]{(1+r)^{12})} = \sqrt[12]{2}$

$1 + r = 1.05946$

$P(t) = 300(1.05946)^{t}$

How large will the population be in 36 years

This is P(36)

$P(t) = 300(1.05946)^{36} = 2400$

The population will be of 2400 in 36 years.
