Answer:
3/5 y +9/10 z
Step-by-step explanation:
4/5 y + 7/10 z - 1/5 y + 1/5 z
4/5 y - 1/5 y + 7/10 z + 1/5 z
We need to get a common denominator for the z term of 10
4/5 y - 1/5 y + 7/10 z + 1/5 *2/2 z
4/5 y - 1/5 y + 7/10 z + 2/10 z
3/5 y +9/10 z
52 inches - 12 inches = 40 inches
amplitude: a = 40 inches / 2 = 20
<span>f(x)=20cos(bx)+c</span>
the value of c is 32... since the centre of the has been moved up 32 units
the minimum amplitude = 32 - 20 = 12
the maximum amplitude = 32 + 20 = 52
<span>f(x)=20cos(bx)+32</span><span>
if the curve takes 6 1/4 hours from low to high tides (9:15 am to 3:30 pm) then it will take 12 1/2 hours to complete a full cycle.
adjust the period by converting 12 1/2 hours to an angle measure.
360</span>°/12 = 30°
30° / 12 = 15°
12 1/2 = 360° + 15° = 375°
f(x) = 20 cos(375°) + 32
f(x) = 20 * 0.97 + 32
f(x) = 19.4 + 32
f(x) = 51.4
Answer:
C. 2x + 10 = 39.88
Step-by-step explanation:
2x will give you the price of the 2 shirts and you have to add the fee of $10 to get the total of $39.88
