A study on the population of wolves is being done in a county to determine how the number of wolves has changed over time. The p

mr_godi [17]

Answer:

Step-by-step explanation:

The population of wolves is given by P(t) = 80(0.98)t.

The study has began in the year of 2000 and will end in 2020.

The difference between 2000 and 2009 is 9 years and the difference between 2009 and 2020 is 11 years.

Hence, the maximum value of t is 11.

The domain is $0 \leq t \leq 11$ .

The population will be 80, that is P(t) = 80.

Hence, 0.98t = 1, or, t = $\frac{1}{0.98} = \frac{100}{98} = \frac{50}{49}$ ≅1.

In (2009 + 1) = 2010, the population of wolves will be 80.

Answer:

$2400

Step-by-step explanation:

The question is asking the amount invested in fund B. We can let 'b' represent that amount. Then the amount invested in fund A is (6000-b). The total profit from the investments is ...

0.02(6000 -b) +0.07(b) = 0.04(6000)

120 +0.05b = 240 . . . . . simplify

0.05b = 120 . . . . . . . . . subtract 120

b = 2400 . . . . . . . . . . .divide by 0.05

Alonzo invested $2400 in fund B.

Help with this please

Alik [6]

Answer:

Yes, the given parallelogram is a rectangle.

Step-by-step explanation:

The vertices of parallelogram are J(-5,0), K(1,4), L(3,1) and M(-3,-3).

The slope formula is

$m=\frac{y_2-y_1}{x_2-x_1}$

$JK=\frac{4-0}{1-(-5)}=\frac{4}{6}=\frac{2}{3}$

$KL=\frac{1-4}{3-1}=\frac{-3}{2}$

$LM=\frac{-3-1}{-3-3}=\frac{-4}{-6}=\frac{2}{3}$

$JM=\frac{-3-0}{-3-(-5)}=\frac{-3}{2}$

The slopes of opposites sides are same it means they are parallel to each other.

The product of slopes of two consecutive sides is

$\frac{2}{3}\times \frac{-3}{2}=-1$

Since the product of slopes of two consecutive sides is -1, therefore the consecutive sides are perpendicular to each other.

Yes, the given parallelogram is a rectangle.
