1 answer:

5 0

The quastion is asking us to determine the measure of angle M in a right triangle LMN. We know that angle N is a right angle and that LM = 76 ( Hypotenuse ) and MN = 40 ( Adjacent ). We will use trigonometry: cos M = Adjacent / Hypotenuse = 40 / 76 = 0.5263158; M = cos^(-1) 0.563158; M = 58.242° = 58° 15`. Answer: The measure of angle M is 58°15`.

Given the functions f(x) = 3(0.56)^x and g(x) = 6(4)^x

rodikova [14]

A) f(x) is decreasing because the base is less than 1.
0.56 is close to 0.5, so its like saying that you are taking half each time, therefore the value is getting smaller.

g(x) is increasing because the base is greater than 1.
you are multiplying by 4 each time, making the value bigger.

B ) The y-intercept is where x=0.
Anything to the '0' power is 1. Therefore the y-intercept is equal to the coefficient in front of each function.
f(x) = 3 , g(x) = 6

C) Just plug in x=4 to each function in a calculator.
f(4) = 0.295
g(4) = 1536

A study of king penguins looked for a relationship between how deep the penguins dive to seek food and how long they stay under

Temka [501]

M = slope
b = y-intercept 

your slope is .0138 

(2) plug 190 in for D and solve: 
DD = 2.69 + .0138(190) 
DD = 5.312 minutes
Hope this Helps!
