Answer:

$y=2.75$ units.

Step-by-step explanation:

We have been given that the bottom of a vase is a square. Each side measures y+11 units. The square has a perimeter of 55 units.

Since we know that all sides of square are of equal measure and the perimeter of a square is 4 times the length of each side.

$\text{Perimeter of square}=4\times\text{Length of each side}$

Upon substituting our given values in above formula we will get,

$55=4\times (y+11)$

Upon distributing 4 we will get,

$55=4y+44$

Upon subtracting 44 from both sides of our equation we will get,

$55-44=4y+44-44$

$11=4y$

Upon dividing both sides of our equation by 4 we will get,

$\frac{11}{4}=\frac{4y}{4}$

$2.75=y$

Therefore, the value of y is 2.75 units.

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

$f(x)= 4(4)^x$

3 times a year

so x becomes 3x

$f(x)= 4(1+r)^{3x}$

$4(4)^x=4(1+r)^{3x}$

Take log on both sides

$log(4)^x=log(1+r)^{3x}$

Use log property and move exponent before log

$xlog(4)=3xlog(1+r)}$

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

$f(x)= 4(1+r)^{3x}$

so equation becomes

$f(x)= 4(1.59)^{3x}$

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Dominik [7]

0.5 cups of cheese

Amy: 1.6 divided by 8 = 0.2 cups of cheese per serving

Sarah: 2.5 divided by 10 = 0.25 cups of cheese per serving

0.25 - 0.2 = 0.5

you are riding your bike. At 10:04am you have riddden your bike 23 miles. By 10:17am you have ridden 179 miles. Find the rate of

Doss [256]

The answer is 720 mph, since we make time the x and distance y. We use the slope formula (y2 - y1)/(x2 - x1)

(179-23)/(17-4)

156 miles/13 mins

12 miles per min

Since the answer is in hours instead of minutes, we multiply 12 by 60 to get 720 mph
