So we are given the equation
y = 79.31(1.48)ˣ
Whereas the x represents the number of days <--- what you need to know
y is the final number you are going to get, does not matter for now
You are trying to find the number of bacteria on Day 8
Put 8 into x

1.48⁸ = 23.019
79.31 * 23.019 = 1825.667
Your answer would be A.

Find the length of both of the unknown sides in the triangle shown here.
icang [17]

Answer:

(x+11)^2 = (x+3)^2 +16^2

And if we solve this equation for x we got:

x^2 +22x +121 = x^2 +6x +9 +256

We can cancel x^2 in both sides and we have this:

22x -6x= 256+9-121 =144

And then we got:

16 x= 144

x =\frac{144}{16}= 9

And then the length of the sides are 9+11= 20 m for the hypothenuse, 16 for the adjacent side and 9+3 = 12m for the last side.

Lenght of the smaller unknown side: 12m

Lenght of the larger unknown side: 20m

Step-by-step explanation:

For this case we have a right triangle and we can use the Pythagoras Theorem and using the info given by the triangle we can set up the following equation:

(x+11)^2 = (x+3)^2 +16^2

And if we solve this equation for x we got:

x^2 +22x +121 = x^2 +6x +9 +256

We can cancel x^2 in both sides and we have this:

22x -6x= 256+9-121 =144

And then we got:

16 x= 144

x =\frac{144}{16}= 9

And then the length of the sides are 9+11= 20 m for the hypothenuse, 16 for the adjacent side and 9+3 = 12m for the last side side.

Lenght of the smaller unknown side: 12m

Lenght of the larger unknown side: 20m

Using n = 3.14, find the area of a circle with a radius of 16.
KATRIN_1 [288]

Answer:

803.84=A

Step-by-step explanation:

The area of a circle can be found by using the equation \pi r^{2}=A.

\pi r^{2}=A

(3.14)(16^{2})=A

(3.14)(256)=A

803.84=A  and the units are, how ever the radius is measured cubed
