Answer:
503 or C
Step-by-step explanation:
10^2= 10 X 10 = 100
100 x 5 = 500
500 + 3 =503
Answer:
B. II only . . . (-1, 4)
Step-by-step explanation:
The function factors as ...
f(x) = (x +1)(x -4)
The factors are zero when x=-1 and x=4. The value of the function will be negative when one of these factors is negative, between x=-1 and x=4. In interval notation, that interval is ...
(-1, 4) . . . interval for f(x) < 0 . . . . . . interval description II (only)
The answer is the first option.
Answer:
871.5
Step-by-step explanation:
directly proportional
y = kx
y = 12 when x = 14
12 = k(14)
k = 12/14
k = 6/7
--------------------------
what is the value of x when y = 747
747 = (6/7) * x
Multiply both sides by 7/6
747 * 7/6 = x
871.5 = x
Answer:
c. 3
Step-by-step explanation:
y = k sin(5x) + 2 cos(4x)
y' = 5k cos(5x) − 8 sin(4x)
y" = -25k sin(5x) − 32 cos(4x)
y'' + 16y = -27 sin(5x)
(-25k sin(5x) − 32 cos(4x)) + 16(k sin(5x) + 2 cos(4x)) = -27 sin(5x)
-25k sin(5x) − 32 cos(4x) + 16k sin(5x) + 32 cos(4x) = -27 sin(5x)
-9k sin(5x) = -27 sin(5x)
k = 3
