A population of 55 foxes in a wildlife preserve doubles in size every 14 years. The function y equals 55 times 2 Superscript x ​, where x is the number of 14-year periods, models the population growth. How many foxes will there be after 28 ​years?

Answers

Since x is the number of 14-year periods, the first thing we do is divide 28 years by 14. 28/14=2.  Now we use that in our function, [tex]y=55*2^x[/tex].

[tex]y=55*2^2=55*4=220[/tex]
There will be 220 foxes after 28 years.

Final answer:

To find the fox population after 28 years, we use the function y = 55 × 2^x, with x = 2 because 28 years is two 14-year periods. After calculating 2^2 and multiplying by 55, we find that there will be 220 foxes.

Explanation:

To calculate the number of foxes in a wildlife preserve after 28 years, given that the population doubles every 14 years, we start with the function y = 55 × 2^x, where x represents the number of 14-year periods.

Since 28 years is equivalent to 2 periods of 14 years, we will substitute x with 2:

Write down the equation substituting x with 2: y = 55 × 2^2.Calculate the exponent: 2^2 = 4.Multiply the base population by 4: 55 × 4 = 220.

Therefore, after 28 years, there will be 220 foxes in the wildlife preserve.

The price of a gallon of unleaded gas has dropped to $2.81 today. yesterday's price was $2.88 . find the percentage decrease. round your answer to the nearest tenth of a percent.

Answers

The percentage decrease is approximately -2.4%.

To find the percentage decrease in price, we can use the formula:

Percentage decrease = ((New price - Old price) / Old price) * 100

Using the given information, we substitute the values into the formula:

Percentage decrease = ((2.81 - 2.88) / 2.88) * 100

Simplifying the expression, we get:

Percentage decrease = (-0.07 / 2.88) * 100

Converting to a decimal and multiplying by 100, we find:

Percentage decrease = -0.0243 * 100 = -2.43%

Rounding to the nearest tenth of a percent, the percentage decrease is approximately -2.4%.

For the quadrilateral shown below, what is m∠a + m∠c ? A.)53 B.)137 C.)180 D.)233

Answers

I think it's C. I hope this helps!!

The value of the given expression m∠a + m∠c is 233 degrees and this can be determined by using the given data.

Given :

Quadrilateral ABCD.Angle B is 95 degrees.Angle D is 32 degrees.

The following steps can be used in order to determine the value of the given expression:

Step 1 - The sum of interior angles of the quadrilateral is 360 degrees.

Step 2 - According to the given data, angle B is 95 degrees and angle D is 32 degrees.

Step 3 - So, the value of the given expression can be calculated as:

[tex]\angle A+\angle B+\angle C+\angle D = 360[/tex]

[tex]\angle A+95+\angle C+32 = 360[/tex]

Step 4 - Simplify the above expression.

[tex]\angle A+\angle C = 360-95-32[/tex]

[tex]\angle A+\angle C = 233[/tex]

Therefore, the correct option is D).

If your front lawn is 15.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1450 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? Assume an average snow flake has a mass of 1.70 mg.
.. ......

it's my first college chm and I forgot how to do such word problems, would you help me please, thank you

Answers

First determine how many square feet there are in the front lawn. 
 (15.0 ft) x (20.0 ft) = 300. ft^2 
 Now find how many snow flakes land in the entire lawn. 
 (300. ft^2) x (1450 snow flakes/min/ft^2) = 435,000 snow flakes/min 
 Now find the total mass of snow landing on the lawn per hour. 
 (435,000 snow flakes/min) x (1.70 mg/snow flake) x (1 kg/1,000,000 mg) x (60 min/1hour) = 44.4 kg of snow per hour.

What is the solution of 3+ (x-2)/(x-3) <=4

X<3
X<=3
X>3
X>=3

Answers

I believe that it's x<3

Answer:

A. X < 3.

Step-by-step explanation:

We have the equation, [tex]3 + \frac{x-2}{x-3} \leq 4[/tex]

Adding -4 on both sides, we get,

[tex]\frac{x-2}{x-3} -1 \leq 0[/tex]

i.e. [tex]\frac{x-2-x+3}{x-3} \leq 0[/tex]

i.e. [tex]\frac{1}{x-3} \leq 0[/tex]

So, we have the inequality [tex]\frac{1}{x-3} \leq 0[/tex].

Its critical points are given by  x-3 = 0 which implies x = 3.

Now, we will find the region among the two [tex]( - \infty , 3 )[/tex] and [tex]( 3 , \infty )[/tex] that satisfies the inequality [tex]\frac{x-2}{x-3} -1 \leq 0[/tex]

Substitute x = 2 in the above inequality, we get -1 < 0, which is true. Again, substitute x=4 gives 1 < 0, which is false.

As x=4 lie in the region  [tex]( 3 , \infty )[/tex] , it cannot be the solution of the given inequality.

So, the solution of the given inequality is the region [tex]( - \infty , 3 )[/tex] .i.e. x < 3.

Hence. option A is correct.

Kelly is hanging shelves in her closet. She can buy shelves for $1.25 a foot. Kelly buys one 5-foot shelf and a shelf that measures 24 inches. The rest of her materials cost $90. How much change will she get it she pays with $100?

Answers

Hello!

There are 12 inches in a foot.

Kelly buys two shelves that measure 7 feet altogether, and the cost of each foot is $1.25.

Multiply the number of feet by the cost per foot.

7 × 1.25 = 8.75

Add this to the cost of the rest of her items.

90 + 8.75 = 98.75

Finally, subtract this from the $100 Kelly will use to pay.

100 - 98.75 = 1.25

ANSWER: Kelly will receive $1.25 change after her payment.

Two integers are x and y
sum of two integers (x+y) = 26
x = 2 + 3y
plug that into equation above:
x + y = 26
(2+3y)+y = 26

4y = 24
4y/4 = 24/4

There are web sites and videos that stand ready to show you how to bisect an angle.

The basic idea is that you draw an arc through both rays so that the points of intersection are the same distance from the vertex. Then, you construct a perpendicular bisector of the segment between those intersection points. That will bisect the angle.

For (3), you bisect each of the angles made by the original bisector. (1/2 of 1/2 = 1/4)
