Answer:
Step-by-step explanation:
in quadrant 1 cos and sec are positive.
cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13
secθ=13/5

Just replace the N of the function F(N) with the requested value - 10:
F(N) = 2N + 3
F(- 10) = 2 · (- 10) + 3 <em>now N has been replaced by - 10</em>
F(- 10) = - 20 + 3
<h2>F(- 10) = - 17</h2>

Step-by-step explanation:
<h3>Part A</h3>
<u>Multiply the energy produced in 1 second by the number of seconds:</u>
- erg
<h3>Part B</h3>
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
F(x) = mx + b is just equal to the equation
y = mx + b
In order for us to get the inverse function, then we can interchange x to y and y to x
y = mx + b
x = my + b
Then we need to find y
x = my + b
-my = -x + b
my = x - b
y = (x-b) / m
f(x) = (x - b) / m
