An initial population of 415
ducks increases at an annual
rate of 32%. Write an
exponential function to model
the duck population.
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Armando used algebra tiles to represent the product 3 x (2 x minus 1). An algebra tile configuration. 3 tiles are in the Factor 1 spot and are labeled + x. 3 tiles are in the Factor 2 spot: 2 are labeled + x and 1 is labeled negative. 15 tiles are in the Product spot: 2 are labeled + x squared, 4 are labeled + x, 1 is labeled negative x, and 4 are labeled negative. Which is true regarding Armando’s use of algebra tiles? He used the algebra tiles correctly. He did not represent the two original factors correctly. The signs on some of the products are incorrect. Some of the products do not show the correct powers of x.
Answer:
Some of the products do not show the correct powers of x.
Step-by-step explanation:
From the picture,
3x(2x - 1) = 6x² - 3x
The correct display on the tile should look like this :
_____+x ______ +x ______ +x
+x __ +x² ______+x² ______+x²
|
+x__ +x² ______ +x² ______+x²
|
- ___ -x _______ -x _______-x

Carol is comparing two rectangular tiles for a flooring project. The blue tile is 8 centimeters long and 6 centimeters wide. The yellow tile is is 70 milimeters long and 68 milimeters wide. Which tile covers the greater area? How much greater is the area. Use the sentence frame to answer.=: The_____ Tile covers more area by ________.
Answer:
The Blue Tile covers more area by 40 mm^2
Step-by-step explanation:
convert centimeter to millimeters
1cm = 10 mm
(6 x 10) by (8 x 10)
Area of a rectangle = length x breadth
60 x 80 = 4800
70 x 68 = 4760
difference = 4800 - 4760 = 40

Please help me out with this no links and no stealing points
Answer:
TQ = 24
Step-by-step explanation:
Δ RST and Δ RPQ are similar, thus ratios of corresponding sides are equal, that is
[tex]\frac{RS}{RP}[/tex] = [tex]\frac{RT}{RQ}[/tex] , substitute values
[tex]\frac{15}{35}[/tex] = [tex]\frac{18}{RQ}[/tex] ( cross- multiply )
15 RQ = 630 ( divide both sides by 15 )
RQ = 42
Then
TQ = RQ - RT = 42 - 18 = 24
Which of the following is an example of scale?

Room holds 1427 rubber ducks
Pls help me :3
Answer:
12 inches in 1 foot
Step-by-step explanation:
In this problem, we need to find an example that is a scale.
There must be a relation between two units.
There are many types of units of lengths. These can be metre, cm, mm, foot, inches.
The relation between inch and foot is given by :
1 foot = 12 inch
So, we can say there are 12 inches in 1 foot.
Hence, the correct option is (c).
