Answer:
The measure of the angles are 40 degrees and 50 degrees
Step-by-step explanation:
Let
x ----> the measure of one angle in degrees
y ----> the measure of the complementary angle in degrees
we know that
If two angles are complementary, then their sum is equal to 90 degrees
so
----> equation A
we have that
----> equation B
Substitute equation B in equation A and solve for y
Find the value of x
therefore
The measure of the angles are 40 degrees and 50 degrees
Answer:
Step-by-step explanation:
<u>Find the area of the garden:</u>
- A = 1/2bh
- A = 1/2(8)(15) = 60 m²
<u>Number of plants:</u>
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
f(x) = (x - 4)^2 - 5
Vertex (4 , -5)
This function opens upward and has min. value = -5
So range y >= - 5
So answer is A. -5 <= f(x) < ∞
The total cost is c the you just multiply 14 by the number of hours so it would be C=$14h
