Answer:

32 years

Step-by-step explanation:

y = years

1 foot  = 12 inches

12 × 8 = 96

Now, plug in random numbers into the expression below to find how long it takes for the tree to grow 8 feet.

3y

3 × 10 = 30

3 × 20 = 60

3 × 30 = 90

3 × 31 = 93

3 × 32 = 96

It will take the pine tree 32 years to grow 8 feet, or 96 inches.

the price of milk in 2013 was around $3.28 a gallon. This was eight times as much as you would have probably paid for a gallon o
Jlenok [28]

The cost of the milk is \fbox{\$\,0.41{\text{ a gallon}}} in 1950s.

Further explanation:

The price of milk in 2013 was around \$3.28 a gallon.

And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.

It is given that the price of milk in 2013 is \$3.28 a gallon.

Assume the price of milk in 1950 be \$x a gallon.

Now, given that 8 times of x is the price of milk in 2013.

Therefore, 8x is the price of milk in 2013 and also \$3.28 is the price of milk in 2013.

Equating 8x and  \$3.28 equal as both are the price of milk in 2013 as,

\begin{aligned}8x&=3.28\\x&=\frac{{3.28}}{8}\\x&=0.41\\\end{aligned}

Here, x is the price of milk in 1950.

Therefore, the cost of the milk is \fbox{\$\,0.41{\text{ a gallon}}} in 1950s.

Lunna [17]

Answer:

x = 2010

Step-by-step explanation:

It is difficult separating and organizing the data.  The best I can see is that the question is asking what is the value of x to make f(x) = t(x) true.  x = 2010  is a year in which enrollment was the same, 740, in both f and t.

How do I find the y coordinates of the vertex of a parabola?
Bess [88]

Answer:

My example:

1. Get the equation in the form y = ax4 + bx + c

2. Calculate -b / 4a. This is the x coordinate of the vertex

3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.

Step-by-step explanation:

y=2x^2 -16x +30

vertex: ( 4, -2)

Focus: (4, -15/8)

Axis of symmetry: x = 4

Directrix: y = -17/8
