There is enough fencing to surround the dog's play yard. The yard must have a perimeter of n more than 38 feet. The length of th

Ierofanga [76]

Answer:

Step-by-step explanation:

Let y = length of side parallel to the side with no fence

x = length of each of the other two sides

Then, y+2x = 64. So, y = 64-2x

Area = A = xy = x(64-2x)

The graph of the area function is a parabola opening downward with a highest point and with x-intercepts (0,0) and (32,0).

By the symmetry of the parabola, the x-coordinate of the maximum point lies halfway between the x-intercepts.

So, the area is maximized when x = 16 ft

y = 64 - 2x = 32 ft

Maximum area = xy = (16)(32) = 512 ft2

To maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.

For the fixed given perimeter, the maximum area which can be obtained is a square.

So for 3 sides= 64 feet

one side = 64/3

The maximum area is 64/3*64/3 square feet

A bank advertises an interest rate of 4% per year, compounded monthly

Darina [25.2K]

Given :

Interest rate , r = 4 %.

To Find :

The APY .

Solution :

APY is given by :

$APY=(1+\dfrac{r}{n})^n-1$

Here , r is compound interest and n is number of time compounded .

So ,

$APY=(1+\dfrac{r}{n})^n-1\\\\APY=(1+\dfrac{4}{12})^{12}-1\\\\APY=30.57\%$

Therefore , APY is 30.57 % .

Hence , this is the required solution .

Jada can bake 12 cookies in 30 minutes. A this rate, how long will it take her to bake 144 cookies?

Elodia [21]

6 hours

Working;
If 12 cookies take 30 minutes,
Then one cookie takes $\frac{30}{12}$

144 cookies would take <span> $\frac{30}{12}$ * 144
=360 minutes or 6 hours</span>

Simplify this expression<br> x² x x x x

cupoosta [38]

Although x ² and x both have the variable x, you can’t add them together. So x + x + x + x is 4x and we just leave x ² the same. So the simplified expression is x ² + 4x. I hope this helped!!
