The answer: cougar population is 9 times the bear population

Step-by-step explanation:

∵ x = 15 ⇒ 15 years after study time

∵ f(x) = 830(0.8)^15 = 29.203 ≅ 29

From the table the cougar population after 15 years = 226

∴ The cougar population = 266 ÷ 29 = 9.172 ≅ 9 times the bear population

The function f(x)=-(x-3)^2 +9 can be used to represent the area of a rectangle with the perimeter of 12 units, as a function of

Ivenika [448]

Maximum area of the rectangle is $9cm^{2}$

<u>Explanation:</u>

<u></u>

Considering the dimensions to be in cm

$f(x) = -(x-3)^{2} +9\\f(x) = -(x^{2} +9 - 6x)+9\\f(x) = -x^{2} +6x\\f'(x) = -2x+6\\-2x+6 = 0\\2x=6\\x=3cm\\\\$

Putting the value of x = 3

$Perimeter = 2(x+b)\\12 = 2(3+b)\\6 = 3+b\\b= 3cm$

$Area of rectangle = x X b\\ = 3 X 3\\ = 9cm^{2}$

Therefore, maximum area of the rectangle is $9cm^{2}$

Point P partitions the directed segment from A to B into a 1:3 ratio. Q partitions the directed segment from B to A into a 1:3 r

AnnyKZ [126]

Dividing the line segment AB into ratio 1:3 or 3:1 means dividing the line segment into four equal lengths, as shown in the diagram below.

Point P is the point that divides the line into 1 part and 3 parts, from A.

Point Q is the point that divides the line into 1 part and 3 parts, from B

Hence, P and Q are points on different position

Jade and Eliza went shopping at a mall. Jade spent $10 more than 5 times the amount that Eliza spent. Jade spent a total of $150

DaniilM [7]

Answer:

140

Step-by-step explanation:

Let total money spent by Eliza's be represented as x

Five times amount Eliza spent = 5x and total amount spent by Jade is $150

So it will be $10+ 5x =$150

5x= 150- 10

5x= 140

x = 140÷5

x= 28

........................

So therefore Eliza's amount spent = $28 and

5x$28 = $140

Jade spent $10 more equals $10+$140= $150(Total money spent by Jade).
