15,000 blue trout were released into the Meherrin River for a scientific study. The function, f(x) = 15,000( _ 9 8 ) x , represents the number of blue trout after x years. In 5 years, what happens to the population?

the answer is Chelsea spent more than $12.75

Option 4, 'Chelsea spent more than $12.75,' matches the given inequality d > 12.75, as it directly corresponds with the 'greater than' symbol in the inequality. So, option 4 is correct.

The inequality d > 12.75 translates to "d is greater than 12.75." Looking at the options provided, we can find a situation that matches the inequality by understanding the meaning of the inequality symbol. Option 4, which says "Chelsea spent more than $12.75," directly corresponds to the inequality given. In this scenario, the amount Chelsea spent (d) is greater than $12.75, which is exactly what the inequality d > 12.75 signifies.

Answer:

The mean will stay the same.

The standard deviation will decrease.

Step-by-step explanation:

For the 5 cards, she has received, the mean will be:

μ=(∑x)/n

=125/5

=25

The mean is 25 and the standard deviation is 10.  

σ=10

If a new card is received with $25, then the sum will be $150  

So the new mean will be:

μ'=(∑x)/n

=150/6

=25

And the new standard deviation will be:  

σ'= 9.12

We can clearly see that  

μ= μ'

and

σ> σ'

So the mean will remain the same and standard deviation will decrease. .

You're correct

The slope is -2/5; and the y-intercept is  -1/3

Step-by-step explanation:

Slope = (-13/30 + 1/30) / (1/4 + 3/4)

= (-12/30) / ( 4/4)

= - 2/5

Slope intercept form: y = mx + b, where b = y-intercept

b = y - mx

b = (-3/5) - (-2/5)(2/3)

b = -3/5 + 4/15

b = -9/15 + 4/15

b = -5/15

b = -1/3

Answer

Slope = -2/5; y-intercept = -1/3

The slope and the y-intercept of the linear function is;

Option A; slope is -2/5 and y-intercept is -1/3

      m = (y2 - y1)/(x2 - x1)

Let's make use of the first 2 coordinates to get the slope;

x1 = -3/4

x2 = -1/2

y1 = -1/30

y2 = -2/15

m = (-2/15 + 1/30)/(-1/2 + 3/4)

m = (-1/10)/(1/4)

m = -2/5

We know equation of a line in slope intercept form is;

y = mx + c

where m is slope and c is y-intercept

-1/30 = (-2/5)(-3/4) + c

-1/30 - 3/10 = c

c = -1/3

Thus, y-intercept is -1/3 and slope is -2/5

-2 9/10, -2 5/8, -2 1/3

Answer:

The answer is -2.9, -2[tex]\frac{5}{8}[/tex], -[tex]\frac{7}{3}[/tex]

Step-by-step explanation:

Since the numbers get higher, the negative numbers that are like -2.9 and -2.3 are considered to be less than -1.9 because they are on the left side further from -1.9 and since -1.9 is closer to 0, it is greater than -2.9 and -2.3. The way I explained is just an example.

Answer:

It only counts as a zero when the y-intercept is (0,0).

Step-by-step explanation:

The zeros of a quadratic function are always written as (x,0), while the y-intercept is always written as (0,y). Therefore, in order for a y-intercept to be a zero, it must be (0,0), because the y-coordinate in any zero is 0. At any other time, the y-intercept is not a zero.

Final answer:

The y-intercept represents the starting value of the relationship when x is zero, but it is not considered a zero itself.

Explanation:

The y-intercept, also represented as 'b' in the equation y = mx + b, is the point where the line intersects the y-axis. It indicates the starting value of the relationship when x is zero. However, the y-intercept does not count as a zero because it represents a specific value on the y-axis, rather than being a zero value on the x-axis. For example, if the y-intercept is 5, it means that the line starts at the point (0, 5) on the coordinate plane.

Look at x = -2 on the graph (on the x-axis).  Draw a vertical line through x = -2.  If this line passes through a dark dot (which indicates that a y-value is associated with that x-value), we have evaluated the function.  The dot in question is (-2, 0) (dark dot).  The same vertical line passes through (-2, -2), but this is not the correct y value for x = -2 (it's an open circle).

The perimeter of a square piece of cardboard with each side measuring 7/12 meter is found by using the formula P = 4a. After calculation, the perimeter is 2 1/3 meters.

The question asks us to calculate the perimeter of a square piece of cardboard with each side measuring 7/12 meter. To find the perimeter of a square, we use the formula P = 4a, where 'P' is the perimeter and 'a' is the length of one side. Since all sides of a square are equal, we simply multiply the length of one side by 4.

In this case, the length of one side (a) is 7/12 meter, so the perimeter (P) would be:

P = 4 × (7/12 meter)
P = (4 × 7/12) meter
P = 28/12 meter
P = 7/3 meter (after simplifying)
P = 2 1/3 meters (in mixed numbers)

Therefore, the perimeter of the square piece of cardboard is 2 1/3 meters.

[tex]y=7x-6\\\\x=7y-6\\\\x+6=7y\\\\y=\frac{x+6}{7} \\\\f^{-1} (x)=\frac{x+6}{7}[/tex]

The inverse of the given function [tex]f^{-1}(x)=\frac{x+6}{7}[/tex].

We have given that,F(x) = 7x - 6

We have to determine the value of the inverse function.

An inverse is a function that serves to undo another function.

The diameter of the cylinder is approximately 22.94 inches.

To find the diameter of the cylinder, we can use the formula for the volume of a cylinder:

Volume [tex]= \pi \times r^2 \times h,[/tex]

where π is a mathematical constant (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.

Given that the height of the cylinder is 7 inches and the volume is 2,908.33 cubic inches, we can rearrange the formula to solve for the radius:

Volume [tex]= \pi \times r^2 \times h[/tex]

[tex]2,908.33 = \pi \times r^2 \times 7[/tex]

Dividing both sides of the equation by 7π, we have:

[tex]r^2[/tex] = 2,908.33 / (7π)

[tex]r^2[/tex] ≈ 131.50

Taking the square root of both sides, we get:

r ≈ √131.50

r ≈ 11.47.

The radius of the cylinder is approximately 11.47 inches.

To find the diameter, we multiply the radius by 2:

d = 2 [tex]\times[/tex] r

d ≈ 2 [tex]\times[/tex] 11.47

d ≈ 22.94

ANSWER

12 ft

EXPLANATION

The volume of a cylinder is calculated using the formula

[tex]V=\pi {r}^{2} h[/tex]

From the question, the volume was given as 540π ft³ .

The height is given as 15 ft.

We substitute the values to obtain:

[tex]540\pi=\pi {r}^{2} \times 15[/tex]

This implies that;

[tex] {r}^{2} = \frac{540\pi}{15\pi} [/tex]

We simplify to get;

[tex] {r}^{2}=36[/tex]

Take positive square root to obtain:

[tex]r = \sqrt{36} [/tex]

[tex]r = 6ft[/tex]

The diameter is twice the radius.

Hence the diameter is 12ft

The answer is:

The diameter of the cylinder is equal to 12 feet.

Why?

To find the diameter of the cylinder we need to use the formula to calculate its volume.

So,  we have:

[tex]Volume=\pi *r^{2}*h[/tex]

We are given the following dimensions of the cylinder:

[tex]Volume=540\pift^{3}\\\\Height=15ft^{3}[/tex]

Now, using substituting and isolating the radius in order to find the diameter, we have:

[tex]Volume=\pi *r^{2}*h\\\\r^{2}=\frac{Volume}{\pi *h} \\\\r=\sqrt{\frac{Volume}{\pi *h} }[/tex]

Therefore, we have:

[tex]r=\sqrt{\frac{Volume}{\pi *h}}\\\\r=\sqrt{\frac{540\pi ft^{3}}{\pi *15ft}}\\\\r=\sqrt{36ft^{2} }=6ft[/tex]

We know the radius, then, calculating the diameter we have:

[tex]diameter=2*radius=2*6ft=12ft[/tex]

Hence, we have that the diameter of the cylinder is equal to 12 feet.

Now simplify the numerator

[tex]f(g(x))=\frac{(5x-4)-3}{5x-4}=\frac{5x-7}{5x-4}[/tex]

To find out domain we set the denominator =0 and solve for x

log3 81 = 4

Step-by-step explanation:

Convert the exponential equation to a logarithmic equation using the logarithm base (3)(3) of the right side (81)(81) equals the exponent (4)(4).

log3(81)=4

or

you can remember this

loga Y= X

so, a^x =y

The logarithmic form of the equation 81=3^4 is log3 81 = 4. It uses the base number 3 (which is being raised to a power), the result of the multiplication (81), and the number of times 3 is multiplied by itself (4).

The logarithmic form of the equation 81=3^4 can be found by applying the basic principles of logarithms. Remember, a logarithm is another way to express exponentiation, in a format that involves the base number, the exponent, and the result. Therefore, the logarithmic form of 81=3^4 is written as log3 81 = 4.

To understand this, consider the logarithmic expression log3 81 = 4. The base number (3 in this case) is the number being multiplied repeatedly (the number being raised to a power). The number 81 is the result of this multiplication, and 4 is the number of times base number, 3, is multiplied by itself to get 81. So, in this case, 3 to the power of 4 (3*3*3*3) equals 81.

So, in short, for the equation 81=3^4, the logarithmic form will be log3 81 = 4. This equation reads as "log base 3 of 81 equals 4".
