1. The figure shows a parabola whose vertex is (0,0).
2. The x² indicates that the red parabola shown in the figure is vertical
3. and the sign - indicates that the red parabola opens down.
Therefore, you can conclude that the red parabola has the equation f(x)=-x²
So, the answer is B.
Shifting 4 units down means subtracting 4 from the function value.
So, G(x) = 4 - x²
Thus,
F(x) = G(x) - 4
F(x) = 4 - x² - 4 = - x²
Therefore, the correct answer is option B
2.8y + 6 + 0.2y = 5y – 14
Answers
Answer:
y = 10
Step-by-step explanation:
Simplifying
2.8y + 6 + 0.2y = 5y + -14
Reorder the terms:
6 + 2.8y + 0.2y = 5y + -14
Combine like terms: 2.8y + 0.2y = 3y
6 + 3y = 5y + -14
Reorder the terms:
6 + 3y = -14 + 5y
Solving
6 + 3y = -14 + 5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-5y' to each side of the equation.
6 + 3y + -5y = -14 + 5y + -5y
Combine like terms: 3y + -5y = -2y
6 + -2y = -14 + 5y + -5y
Combine like terms: 5y + -5y = 0
6 + -2y = -14 + 0
6 + -2y = -14
Add '-6' to each side of the equation.
6 + -6 + -2y = -14 + -6
Combine like terms: 6 + -6 = 0
0 + -2y = -14 + -6
-2y = -14 + -6
Combine like terms: -14 + -6 = -20
-2y = -20
Divide each side by '-2'.
y = 10
Simplifying
y = 10
Answer:
y= 11
Step-by-step explanation:
we have:
2.8y + 6 + 0.2y = 5y – 14
or 3y + 6 = 5y -14
and 3y + 6 - 6 = 5y -16 -6
and 3y = 5y -22
and 3y - 5y = -5y +5y -22
so -2y = -22
finally y = -22/-2
or y=11
Hope that useful for you.

V=(ph^3)/12
V(15)=281.25p and since V=10t, t=28.125p
V=(ph^3)/12
dV/dh=(3ph^2)/12=(ph^2)/4 and since V=10t, dV/dt=10
(dh/dV)(dV/dt)=dh/dt=12/(3ph^2)*10
dh/dt=120/(3ph^2) and we want the rate when h=15 so
dh/dt(15)=120/(675p)
dh/dt=0.05658 ft/min
Final answer:
The rate at which the water's depth is increasing when it is 15 feet deep is approximately 0.028 feet per minute.
Explanation:
The subject of the student's question is related to the concept of volumes of revolution and rates of change in calculus. This is a practical application of those principles.
If we use the formula for the volume of a cone, we get: V = 1/3(pi*r²*h). Looking at our provided situation, we see that r = h/2, so we can replace r with h/2, giving us V = 1/3(pi*(h/2)²*h). This simplifies down to V = 1/12*pi*h³.
Next, differentiate the volume with respect to time (t), giving us dV/dt = 1/4*pi*h²*dh/dt. We know that dV/dt = 10 ft³/min (the rate at which water is flowing into the tank), and we want to find dh/dt when h = 15 ft.
Substitute these values into the differentiated equation to solve for dh/dt: 10 = 1/4*pi*(15)²*dh/dt therefore dh/dt = 10 / (1/4*pi*15²) which gives us approximately 0.028 ft/min.
