C- A cube also cannot be "two polygons"
D- A pyramid is not parallel.
ANSWER:
4th option: y = cosine (x + pi)
STEP-BY-STEP EXPLANATION:
For the function y = cosine (x), when x = 0, y = 1 and when x = , y = -1. The graph shows the opposite, when x = 0, y = -1 and when x = , y = 1, so we must add the same amount x = , for y to be positive 1.
So the equation of the graph would be:
The correct answer is then the 4th option y = cosine (x + pi)
Answer: She has 2 cups of paint.
Step-by-step explanation:
1 cup + 1 cup = 2 cups
Find the eqn. of the tangent line to the curve of f(x) = x^2 + 5x -5 at (0,-5).
Differentiate f(x) to obtain an expression for the derivative (slope of the tangent line):
f '(x) = 2x + 5
Subst. 0 for x here: f '(0) = 2(0) + 5 = 5 (at the point (0, -5))
Use the point-slope equation of a str. line to find the eqn of the tan. line:
y-k = m(x-h), where (h,k) is a point on the line and m is the slope:
y - [-5] = 5(x-0), or y+5 = 5x. Then y = 5x - 5 is the eqn. of the TL to the given curve at (0,-5).
Answeryou'll be able to ride 14 miles.
Step-by-step explanation:
Your price is 29.50. if the first mile is 3.50 you'll subtract that from the 29.50 you originally had. Now you're left with 26.00. If you divide that by the two dollars you pay for every next mile you'll have 13 miles. Now add that first mile and you have 14. Hopefully this made sense!
