What is the value of h(–2) when h(x) = 3x 1

1 answer:

7 0

Is it 3x+1 or 3x-1?

if it is +1 then the problem looks like this : h(-2)= 3(-2)+1 = -6+1=-5
if it is -1 then the problem looks like this : h(-2) = 3(-2)-1 = -6-1 = -7

There are 8 yellow and 24 blue. Our ratio from yellow to blue is 8:24.
To simplify this, we need to see if we can divide 8 and 24 by a common factor.
8 and 24 can be divided by 8, so let's do that.
8/8 = 1.
24/8 = 3.
Your new and simplified ratio is 1:3 from yellow to blue, but we're looking for blue to yellow. Flip the ratio.
3:1 is your ratio.
C.) is your correct answer.
I hope this helps!

Apply the Pythagorean Theorem to find the distance between points A and B.

irinina [24]

Answer:

Properties of a right tangle can be created in a Coordinate Plane

Distance between two points A and B are shown as below

Step-by-step explanation:

Find distance between two point using Pythagorean Theorem.

Properties of right triangles and creating right triangle as a coordinate Plane.

Suppose two point are drawn in triangle containing value of (-2 , 4 ) and (-2, -2)

then

In (-2 , 4 ) and (-2,-2)

taking y-values that is 4 and -2

find difference between them such as

4-(-2) = 6

Distance is (-2,4) is 6 unit from (-2,-2)

We can also find unit length of A and B

Side A: (-1, 2) and (3,2)

3-(-2) = 5

side A is 5 unit in length

Side B : (-2,2) and (-2,-1)

2 - (-1) = 3

Side B is 3 unit in length

Option a: The number of bacteria at time x is 0.

Option b: An exponential function that represents the population is $y=200(1.5)^x$

Option c: The population after 10 minutes is 11534(app)

Explanation:

It is given that the coordinates of the graph are (0,200), (1,300) and (2, 450)

Option a: To determine the number of bacteria x when y = 200

From the graph, we can see that the line meets y = 200 when x = 0

Thus, the coordinates are (0,200)

Hence, the number of bacteria at time x is 0 when y = 200.

Option b: Now, we shall determine the exponential function of the population.

The general formula for exponential function is $y=a \cdot b^{x}$

Where a is the starting point and $a=200$

b is the common difference.

To determine the common difference, let us divide,

$\frac{300}{200} =1.5$

Also, $\frac{450}{300} =1.5$

Hence, the common difference is $b=1.5$

Thus, substituting the values $a=200$ and $b=1.5$ in the formula $y=a \cdot b^{x}$ ,

we have, $y=200(1.5)^x$

Hence, An exponential function that represents the population is $y=200(1.5)^x$

Option c: To determine the population after 10 minutes, let us substitute $x=10$ in $y=200(1.5)^x$ , since the x represents the population of the bacteria in minutes.
