Answer: The city will need 33 trees.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the length of the path (5 1/2 miles) distance between trees (1/6).

Mathematically speaking:

5 1/2 ÷ 1/6 = (5x2+1) /2 ÷1/6 = 11/2 ÷1/6 = (11x6) /(2x1) = 66/2 =33 trees

The city will need 33 trees.

Feel free to ask for more if needed or if you did not understand something.  

Final answer:

To determine the number of trees needed for a roadway with trees spaced every 1/6 mile along a 5 1/2-mile path, divide the total distance by the spacing distance to find 33 trees required.

Explanation:

Roadway:

To find the number of trees needed, we first calculate the distance between trees: 1/6 mile. The total length of the road is 5 1/2 miles, so we divide the total length by the distance between trees to find the number of trees needed:
5 1/2 miles ÷ 1/6 mile = 5.5 ÷ 1/6 = 5.5 * 6 = 33 trees

Answer:

1/4

1

4

Step-by-step explanation:

The function is g(x) = 4^((1/2)*x)

For A, the value is -2.  Plug this into the equation.

g(-2) = 4^((1/2)*-2)

g(-2) = 4^(-1)

g(-2) = 1/4

For B, the value is 0.  Plug it into the equaiton.

g(0) = 4^((1/2)*0)

g(0) = 4^(0)

g(0) = 1

For C, the value is 2.  Plug it into the equation.

g(2) = 4^((1/2)*2)

g(2) = 4^1

g(2) = 4

A function is a relationship between inputs where each input is related to exactly one output.

The value of A is 1/4.

The value of B is 1.

The value of C is 4.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = [tex]4^x[/tex]

g(x) = [tex]4^{\frac{1}{2}x[/tex]

For x = -2

A = [tex]4^{\frac{1}{2}\times-2[/tex]

A = 1/4

For x = 0

B = [tex]4^0[/tex]

B = 1

For x = 2

C = [tex]4^1[/tex]

C = 4

Thus,

The value of A is 1/4.

The value of B is 1.

The value of C is 4.

In the problem, 'X' denotes the cost to rent each pair of skates. Setting up and solving the equation, 9 + 7X = 30, we find 'X', the cost per pair, is $3.

In this problem, 'X' represents the cost to rent each pair of skates. The problem refers to a situation where a skating rink charges $9 for a group rate and an additional fee for every pair of skates rented. According to the provided information, a family who rents 7 pairs of skates pays a total of $30. We can set up an equation to solve for 'X.'

The equation is 9 + 7X = 30, where X is the cost per pair of skates.

To solve this equation, you have to subtract 9 from both sides, getting 7X = 21. Afterward, you divide both sides by 7, and you get X = 3. Therefore, 'X' corresponds to $3, the cost per pair of skates.

An expression that has the same value as (-14) - 8 is (-14) + (-8), both of which equal -22.

The question is about finding an expression that is equivalent to (-14) - 8. When we subtract a positive number from a negative number, we move further to the left on the number line, making the number more negative. Therefore, (-14) - 8 is the same as adding the opposite of 8, which is -8, to -14, giving us -22. Another way to see it is moving 8 units to the left from -14 on a number line.

Thus, an equivalent expression might be the subtraction of the negative of 8, which is (-14) + (-8). We add the two negative numbers together following the rule that adding two negative numbers results in a negative sum. In this case, (-14) + (-8) is also -22.

Answers and Step-by-step explanations:

(a) We want to find the slope-intercept equation (y = mx + b), where m is the slope and b is the y-intercept. We already have two points: (2, 6200) and (7, 21200). The slope is change in y over change in x so:

m = (21200 - 6200) / (7 - 2) = 3000

Now, we have y = 3000x + b. Plug in 6200 for y and 2 for x to solve for b:

y = 3000x + b

6200 = 3000 * 2 + b

b = 200

Nat's equation is y = 3000t + 200.

(b) We want a quadratic formula in vertex form because the problem says that Kat's account maxes out at 44100 on her 25th birthday, indicating that's the vertex. Our vertex point is (20, 44100); note that it's 20 and not 25 because she starts the account at age 5, not age 0. The generic vertex form of a quadratic is:

y = a(x - h)² + k, where (h, k) is the vertex

Plug in our vertex:

y = a(x - 20)² + 44100

We also have the point (9, 32000), so put that in to find a:

32000 = a(9 - 20)² + 44100

-12100 = a * 121

a = -100

So Kat's equation is y = -100(t - 20)² + 44100.

(c) In order to find the age when they have the same amount, we set the two equations equal:

3000t + 200 = -100(t - 20)² + 44100

-100(t² - 40t + 400) + 44100 = 3000t + 200

-100t² + 4000t - 40000 + 44100 - 3000t - 200 = 0

-100t² + 1000t + 3900 = 0

t² - 10t - 39 = 0

(t - 13)(t + 3) = 0

t = 13 or t = -3   --   obviously, years can't be negative, so t = 13.

Note, however, that t is the number of years after Kat and Nat are 5, so we need to add 13 to 5:

13 + 5 = 18

The age is 18.

A: [tex]N(t) = 3000t +200[/tex]

B: [tex]y = -100(x-20)^2+44100[/tex]

C: When they turn 18.

A. Write a linear function N(t) for the amount of money, N, that Nat has in her account ‘t’ years after her 5th birthday:

You can determine a linear equation using the two coordinates provided:

(2, 6200) and (5, 21200).

To do this, first find the slope of the graph. You can do this by using the expression

[tex]\frac{y2-y1}{x2-x1}[/tex], where the coordinate (2, 6200) is 1 and (7, 21200) is 2:

[tex]\frac{21200-6200}{12-7}\\\\\frac{15000}{5}[/tex]

The slope is equal to 3000. Now, you need to find the y-intercept. Plug in 2 for x and see what the y intercept would need to be to equal 6200:

6200 = 3000 * 2 + b

6200 = 6000 + b

b = 200

Thus, your equation for Nat's bank account is [tex]N(t) = 3000t + 200[/tex]

B: Kat’s account doesn’t follow a linear model, but rather a quadratic model. On her 5th birthday, her parents open the account and then add money annually just like with Nat. Kat’s parents plan is to add money so that her account maxes out at $44100 on her 25th birthday. At the age of 14, she has $32000. Write a quadratic function K(t) for the amount of money, K, in Kat’s account ‘t’ years after her 5th birthday:

The question supplies you with the vertex to the parabola, (20, 44100). This is the point at which the maximum value of the function is reached.

It also supplies you with a point on the parabola, (9, 32000).

You can use the vertex form of the quadratic equation to find the formula for Kat's bank account:

[tex]y=a(x-h)^2+k[/tex], where (h, k) is the vertex.

Substituting the vertex in for that equation, we get:

[tex]y=a(x-20)^2+44100[/tex]

Now, you can substitute the point (14, 32000) in for x and y to solve for a:

[tex]32000=a(9-20)^2+44100\\\\-12100 = 121a\\a = -100[/tex]

Thus, the equation is [tex]y = -100(x-20)^2+44100[/tex].

C. What age will both Nat and Kat have the same amount in their account? 18 years old.

To find what age each account will be equal, set the equations equal to each other:

[tex]-100(x-20)^2+44100 = 3000x +200[/tex]

Then, you can solve for x:

[tex]-100(x-13)(x+3)=0[/tex]

Solving for x, we notice that the accounts equal each other when Nat and Kat are -3 or 13. However, Nat's function is only specified to begin after she turns 5, so add 5 to 13 to get 18.

They will both have the same money in their accounts when they turn 18.

To multiply numbers in scientific notation, multiply the coefficients and add the exponents. The final answer is 7.2 x 10^11.

To multiply numbers in scientific notation, you need to multiply the coefficients and add the exponents.

In this case, (9.104) multiplied by (8.106) gives you (9 * 8) multiplied by (104+6).
So the result is 72 multiplied by 1010, which can be written in scientific notation as 7.2 x 1011.

The measure of x from the circle is x = 102

The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.

The central angle of a circle formula is as follows.

Central Angle = ( s x 360° ) / 2πr

where s is the length of the arc

r is the radius of the circle

Central Angle = 2 x Angle in other segment

Given data ,

Let the measure of the external angle ∠GDF = 36°

Now , Central Angle = 2 x Angle in other segment

And , the measure of ∠GAF = ( x + 42 )°

On simplifying , we get

( x + 42 )° = 180° - 36°

x + 42 = 144

Subtracting 42 on both sides , we get

x = 102

Hence , the measure of x of circle is 102

The probability of spinning 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities assuming that they are independent events.

The probability of getting 'green' on the first spinner and 'blue' on the second spinner can be calculated by multiplying the individual probabilities if the two events are independent. If the first spinner has 'g' green out of 't' total possible outcomes and the second spinner has 'b' blue out of 's' total outcomes, the first probability would be 'g/t' and the second one 'b/s'. Hence, the probability of spinning 'green' on the first and 'blue' on the second would be (g/t) * (b/s).

For instance, if the first spinner has 2 green areas out of 10 total (2/10=0.2) and the second spinner has 3 blue areas out of 10 (3/10=0.3), then the probability of spinning 'green' first and 'blue' second would be 0.2*0.3=0.06 or 6%. Remember that the aforementioned explanation assumes that the outcomes from the two spinners are independent, that is, the result from the first does not affect the result from the second.

The probability of spinning green on the first spinner and blue on the second spinner is 1/9.

To calculate the probability of independent events, we need to multiply the probabilities of each event occurring separately.

Assume the first spinner has equal sections for each color: red, blue, and green.

Thus, the probability of spinning green is 1/3.

Similarly, assume the second spinner has equal sections for each color: red, blue, and green.

Thus, the probability of spinning blue is 1/3.

Since the spins are independent events, the overall probability is calculated by multiplying these probabilities:

P(Green on first) * P(Blue on second) = 1/3 * 1/3 = 1/9

The equation for the given line in slope-intercept form is y = (-3/5)x - 1.

Option D is the correct answer.

We have,

The slope-intercept form of a linear equation,

y = mx + b

where m represents the slope of the line and b represents the y-intercept.

The slope (m) of the line using the two given points (0, -1) and (5, -4):

m = (y₂ - y₁) / (x₂ - x₁)

m = (-4 - (-1)) / (5 - 0)

m = (-4 + 1) / 5
