Answer:
no pic or nothing but here is a number 324
Step-by-step explanation:
E=elliptical
T= treadmill
12E+10T=676
also, she worked out one hour
E+T=60
E=60-T we substitute now
12(60-T)+10T=676
720-12T+10T=676
720-2T=676 substract 720 from both sides
-2T=-44 now divide by (-2)
T=22
if T=22 E=60-22=38
she spends 38 min on the elliptical
Answer:
The graph of h(x) is shown below.
Step-by-step explanation:
The given function is

The general form of sine function is

Where, a is amplitude, b is period, c is phase shift and d is vertical shift.
So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.
It means the minimum value of function is -7 and maximum value is 7.
Therefore the points on the function are (0,0),
.
The graph of function is shown below.
Step-by-step explanation:
area of the parallelogram = 7 × 14
=98 cm²
