At the gym, Cara burns 12 calories per minute on the elliptical and 10 calories per minute on the treadmill. If she worked out f
bija089 [108]
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

Graph h(x)=7 sin x ?
dedylja [7]

Answer:

The graph of h(x) is shown below.

Step-by-step explanation:

The given function is

h(x)=7\sin x

The general form of sine function is

f(x)=a\sin(bx+c)+d

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), (-\frac{\pi}{2},-7),(\frac{\pi}{2},7).

The graph of function is shown below.
