Answer:
All of them
Step-by-step explanation:
2/2 is 1, and if the shaded part is 2/2, everything would be shaded.
Answer: This parabola has 0.3875 x-intercepts,
<span>representing the times when the dolphin's height above water is </span>
0 feet.
The x-intercept is the point where the graph crosses the x-axis, which is when the value is y=0.
The calculation for y=0 would be
<span>Y = -16x2 + 32x - 10
</span><span>0 = -16x2 + 32x - 10
</span>-8x2 + 16x - 5=0
-b +-√(b^2-4ac) /2a=
-16 +-√(16^2-4(-8)(-5)) /2(-8) =
-16+- √(256-160/ -16 =
-16+- √(96/ -16 =
-16+- 9.8/ -16 =
x1= 0.3875
x2= -1.6125
Answer:
3/10
Step-by-step explanation:
1/5 of <u>total</u> income - spent on car
<u>remainder</u><u> </u> income = 4/5
3/8 of <u>remainder</u><u> </u>= 3/8 ×4/5 = 3/10(of total income spent on rent)
the word "<u>of</u>" means you can find it by multiplication
e.g. 2 of 1/2 means 2 × 1/2 which is 1

Answer:
AB = 8/ cos 60
Step-by-step explanation:
We want to find the hypotenuse AB
Since we have a right triangle
cos theta = adj/ hyp
cos 60 = 8/ AB
AB cos 60 = 8
AB = 8/ cos 60
