Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) = 2^x + 5x and g(x) = 3x - 5
<h3>To find </h3>
<h3>Solution</h3>
- (f+ g)(x) =
- f(x) + g(x) =
- 2^x + 5x + 3x - 5 =
- 2^x + 8x - 5
Answer:
774 feet.
Step-by-step explanation:
Let x represents how far the ship is from the base of the lighthouse.
We use the tangent ratio, which involves opposite over adjacent to find x.
To the nearest whole number, the distance is 774 ft.
Store 1: $26.62/36=0.74 per oz.
Store 2: $22.42/28=0.80 per oz
So store 1 is .06 cents cheaper than store 2
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
