Answer:
-18
Step-by-step explanation:
Given:
f(x)=4-x^2 and g(x) =6x
h(3) = (g-f)(3)
= 6x - (4x^2)
= 6*3 -(4*3^2)
= 18 - 4*9
= -18
Assume x books are produced.
Then let 53808 + 12.5x = 17328 + 20.5x
Solve for x:
x = 4560
Symmetry means that if you split it in half, the two sides would be equal. For example, the letter X is symmetrical.
Step-by-step explanation:
we simply use the formula and use 3.14 for pi.
so, the circumference is
2×pi×r = 2×3.14×4 = 3.14×8 = 25.12 in
so, D is correct.
1. 42 5/8 + 39 3/5
Find common denominator for the fractions and rewrite them using the common denominator:
5/8 = 25/40
3/5 = 24/40
25/40 + 24/40 = 49/40 = 1 9/40
1 9/40 + 42 + 39 = 82 9/40 feet
2. 9/40 = 0.225, plus 82 feet = 82.225 feet, this is less than 82.5, so the 8th graders earned the 50 points.
3. The equation would be the total of completed jumps divided by the total number of attempts:
(2 +4 + 1) / (3 + 6 +4) = 7/13 = 0.538 average.
4. 0.538 is greater than 1/2 ( 0.50), so the 8th graders earned 50 points.
