Answer:

Option A and C are correct.

Each year the number of mice double

Initial population of mice were 200

Step-by-step explanation:

An exponential function is given by: y=ab^x

where

a is the initial value

b represents the common ratio and

variable x represents the number of years.

Given the function: M = 200(2)^x

where

M represents the Mouse population.

x represents the number of years.

On comparing with above exponential function, we have

a = 200 and b = 2

⇒The initial population of mice(a) were 200 and each year the number of mice double

Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.
riadik2000 [5.3K]
<span>First of all to calculate the distance between two points we can use distance formula
   
d=Square Root [(x2-x1)^2 + (y2-y1)^2]
   
Now substitute the given points p(x1,y1) and q(x2,y2)in above distance formula
   
The values are X2=3, X1=8and Y2=8and Y1=2.
   
After Substituting the values
   
d=Square Root[(-5)^2+(6)^2]
   
d=Square Root(25+36]
   
d=Square Root[61]
   
d=7.8
   
7.8 is the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.</span>

One of my teachers emailed me this can u guys please help? I have no idea what to do TvT pls and thx.
Katen [24]
I think it might be 38
The first equation-
21/3=7
So spider=7
The second-
(17-7)/2=10/2=5
So hat=5
The third-
(11-5)/2=6/2=3
So bat=3
The fourth-
3+5x7=3+35=38

What is the distance between the points (1, 25) and (4, 21)
Elena-2011 [213]

Hello!

To find the distance between the points (1, 25) and (4, 21), you need to use the distance formula.

The distance formula is: d =\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}. With the distance formula, you have to assign the ordered pairs before substituting them into the formula, which is also used to to find the slope of functions.

d =\sqrt{(21-25)^{2}+(4-1)^{2}}

d =\sqrt{(-4)^{2}+(3)^{2}}

d=\sqrt{25}

d=5

Therefore, the distance between the two points is 5 units.

FAST ANSWER PLEASE THANKS

Answer:

(f • g)(x) = x² - 6x + 7

Step-by-step explanation:

Suppose

f(x) = x² - 2

g(x) = x - 3

Determine

(f • g)(x) = ...

We can compose the functions by doing the following

(f • g)(x) = f(g(x))

(f • g)(x) = f(x - 3)

(f • g)(x) = (x - 3)² - 2

(f • g)(x) = x² - 6x + 9 - 2

(f • g)(x) = x² - 6x + 7

I hope this helps!
