<span>A. 8 wreaths, 6 trees, 2 sleighs
Nothing much to do for this problem except to try each option and see if it meets the constraints of available time. So let's check them out.
A. 8 wreaths, 6 trees, 2 sleighs
prep = 8 * 3 + 6 * 14 + 2 * 4 = 116 hours.
paint = 8 * 2 + 6 * 3 + 2 * 15 = 64 hours.
fire = 8 * 9 + 6 * 4 + 2 * 7 = 110 hours.
All three values are less than or equal to the constraints of 116, 64, and 110.
This option will work.
B. 6 wreaths, 2 trees, 8 sleighs
prep = 6 * 3 + 2 * 14 + 8 * 4 = 78 hours.
paint = 6 * 2 + 2 * 3 + 8 * 15 = 138 hours.
138 is more than the allowed 64, can't do this option.
Don't bother to calculate how many hours of firing needed.
C. 9 wreaths, 7 trees, 3 sleighs
prep = 9 * 3 + 7 * 14 + 3 * 4 = 137 hours.
137 is more than the allowed 116, can't do this option.
Don't bother to calculate how many hours of painting or firing needed.
D. 2 wreaths, 8 trees, 6 sleighs
prep = 2 * 3 + 8 * 14 + 6 * 4 = 142 hours.
142 is more than the allowed 116, can't do this option.
Don't bother to calculate how many hours of painting or firing needed.
Of the 4 choices available, only option "A" falls under the required time constraints.</span>
Answer:
Even function
Step-by-step explanation:
Both powers of x in f(x) = -3x^4 + 7x^2 are even, so f(x) = -3x^4 + 7x^2 is an even function.
Our line is parallel to the line y = 0.5 x -7
so they have the same slope ( slope = 0.5)
and passes through the point (-3,-2)
y + 2 =0.5 (x+3)
y + 2 = 0.5 x + 3/2
which leads us to choice A
