The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:

$m=\dfrac{9-(-8)}{-7-(-8)}=\dfrac{17}{1}=17$

Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:

$y-9=17(x-(-7))\\\\\boxed{y-9=17(x+7)}$

How estimation helps you to place the decimal point when multiplying 3.9x5.3

myrzilka [38]

3.9 can be rounded to 4.
5.3 can be rounded to 5.

4 x 5 = 20

That tells you that 3.9 x 5.3 has a digit in the tens place.

Then you can proceed to multiply 39 and 53, which equals 2067.
(Note: I removed the decimals on purpose)

Now we know that in 2067, the 2 should be in the tens place. That means 0 is in the ones place and that 6 is in the tenths place. That leaves 7 to be in the hundreths place.

Therefore, 3.9 x 5.3 = 20.67

Park service personnel are trying to increase the size of the bison population of a large park. If 140 bison currently live in t

natali 33 [55]

Answer:

$y(t) = 140 (2.7)^{0.01t}$

Where t represent the time in years

For this case this model follows the general model given by:

$y = a b^t$

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate

For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

$y(30) = 140(2.7)^{0.01*30} = 188.598$

And if we round to the nearest whole number we got 189 bisons after 30 years

Step-by-step explanation:

For this case we have the following function given:

$y(t) = 140 (2.7)^{0.01t}$

Where t represent the time in years

For this case this model follows the general model given by:

$y = a b^t$

Where a = 140 represent the initial amount of bisons and y the number of bisons after t years and b = 2.7 represent the growth rate

For this case we want to find the value of y when t =30, and if we replace the value of t =30 in our function we got:

$y(30) = 140(2.7)^{0.01*30} = 188.598$

And if we round to the nearest whole number we got 189 bisons after 30 years
