actual distance?
A 1.5 miles C 12.5 miles
B 2.5 miles D 37.5 miles

Answer:

205/6

Step-by-step explanation:

The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.

45=-6/5x+86

-41=-6/5x (subtract 86 from both sides)

-41*(-5)=-6/5x*(-5) (multiply both sides by -5)

205=6x (divide both sides by 6)

205/6=x

Answer:

$0.20

Step-by-step explanation:

A dozen of pencils = $2.40

1 pencil = $2.40 ÷ 12 = $0.20

PLEASE DO MARK ME AS BRAINLIEST UWU

ALSO, DO HAVE A GREAT DAY ;)

The unit price per pencil is determined by dividing the total cost of the pencils ($2.40) by the total number of pencils (12), giving a result of $0.20 per pencil.

To find the unit price per pencil, you would divide the total cost by the total number of items.

In this case, the total cost is $2.40 and there are twelve pencils, so the calculation is $2.40 ÷ 12.

This will give you the unit price per pencil.

Using the numbers provided, $2.40 (the total cost) divided by 12 (the total number of pencils) equals $0.20.

So, the unit price of a pencil is $0.20.

When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.

I hope this helps :)

The greatest common factor (GCF) of the numerator 9x+45 and the denominator x^2 +9x+20 of the provided rational expression is x+5.

The greatest common factor (GCF) is found by factoring both the numerator and the denominator and then identifying the largest factor that appears in both. For the provided rational expression 9x+45 over x2 +9x+20, let's factor both parts:

Comparing both factored forms, we can see that x+5 appears in both the numerator and the denominator, and it is the largest factor common to both. Therefore, the GCF of the numerator and the denominator is x+5.

Answer:

The fraction = 9/35

To find the fraction, calculate the sum of 5 1/3 and 6 1/3, which is 35/3, then divide the final product, 3, by this sum. The fraction that when multiplied by the sum equals 3 is 9/35.

The question asks us to find the fraction when the product of the fraction and the sum of 5 1/3 and 6 1/3 is 3.

First, let's calculate the sum of 5 1/3 and 6 1/3:

5 1/3 can be written as (5*3 + 1)/3 = 16/3.

6 1/3 can be written as (6*3 + 1)/3 = 19/3.

Adding these fractions, we get (16/3) + (19/3) = (35/3).

So, we have the equation:

Fraction  imes (35/3) = 3

To find the unknown fraction, we divide both sides by 35/3:

Fraction = 3 / (35/3) = 3  imes (3/35) = 9/35

Therefore, the fraction we are looking for is 9/35.

Answer:

D. 76.5

Step-by-step explanation:

The summation sign means that it is the sum of the expression for all values of n upto 6.

n = 2 below the summation sign means that n starts from 2.

∑(n-1)!/2 from n= 2 to n=6

= (2-1)!/2 + (3-1)!/2 + (4-1)!/2 + (5-1)!/2 + (6-1)!/2

= 1!/2 + 2!/2 + 3!/2 + 4!/2 + 5!/2

= 1/2 + 2*1/2 + 3*2/2 + 4*3*2/2 + 5*4*3*2/2

= 1/2 + 2/2 + 6/2 + 24/2 + 120/2

Final answer:

The coordinates that form a square when paired with (-3, -2) and (-5, -2) are (-3, 0) and (-5, 0). The sides of the square are 2 units long, and by moving perpendicularly up by 2 units from each given point, we find the other two vertices of the square.

Explanation:

The student has asked which set of coordinates, when paired with (-3, -2) and (-5, -2), would result in a square. To find the coordinates that complete the square, we need to consider that the diagonals of a square are equal in length and bisect each other at right angles. The two given points (-3, -2) and (-5, -2) form a side of the square that is parallel to the x-axis and 2 units long. Since a square has all sides equal, the other two vertices of the square will be 2 units away from these points but in a perpendicular direction.

Here's how we calculate it step by step:

First, we determine the length of the side of the square by calculating the distance between the points (-3, -2) and (-5, -2), which is 2 units.

Next, we move 2 units perpendicularly from each point which can be done by either keeping the x-coordinate constant and changing the y-coordinate or vice versa. Since we want to be perpendicular to the x-axis, we change the y-coordinate.

The change in the y-coordinate could be either upwards (+2) or downwards (-2). Considering the y-value of the given points, one possible set of coordinates for the other two vertices are (-3, 0) and (-5, 0).

Therefore, the coordinates (-3, 0) and (-5, 0), when paired with (-3, -2) and (-5, -2), form a square.

Answer:

x = 0; x = 5

Step-by-step explanation:

2x² = 10x

2x² - 10x = 0

2x(x - 5) = 0

x = 0; x = 5

Answer:

The values of x for which it is true that  [tex]2x^2=10x[/tex]  are:

We have the following equation

[tex]2x^2=10x[/tex]

To solve the equation subtract 10x on both sides of the equation

[tex]2x^2-10x=10x-10x[/tex]

[tex]2x^2-10x=0[/tex]

Now take the variable x as a common factor

Answer:

cos46°

Step-by-step explanation:

Using the co function identity

sin x° = cos(90 - x)°, hence

sin44° = cos(90 - 44)° = cos46°

Answer:  The correct option is (b) cos 46°.

Step-by-step explanation:  Given that when solving for x, the sine of 44º is used.

We are to select the other angle and trigonometric function that could be used to solve for x.

We know that,

the sine of any acute angle is equal to the cosine of its complement.

That is,

if y denotes the measure of any acute angle, then we have

[tex]\sin y=\cos(90^\circ-y).[/tex]

Therefore, if y = 44°, then we get

[tex]\sin 44^\circ=\cos(90^\circ-44^\circ)=\cos 46^\circ.[/tex]

Thus, the other angle and the  trigonometric function that could be used to solve for x is cos 46°.

Option (b) is CORRECT.

Answer:

B and C

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the values that x cannot be.

solve

3x² - 75 = 0 ( add 75 to both sides )

3x² = 75 ( divide both sides by 3 )

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5 → B and C

Answer:

Frequency = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We are given the following function and we are to find its frequency:

[tex]f (x) = 3 cos (\pi x) -2[/tex]

We know that the standard form of cosine function is [tex]y=Acos (Bx)+c[/tex]

where [tex]A[/tex] is the amplitude, [tex]B=\frac{2\pi}{\text{Period}}[/tex] while [tex]c[/tex] is the mid line.

Frequency is given by:

[tex]F=\frac{1}{P}[/tex] where [tex]F[/tex] is frequency and [tex]P[/tex] is the period.

Finding period by comparing the given function:

[tex]y=3cos(\pi x)-2[/tex]

[tex]Period - B = \pi[/tex]

Substituting B to get:

[tex]\pi =\frac{2\pi}{\text{Period}}[/tex]

[tex]\text{Period}=\frac{2\pi}{\pi}=2[/tex]

So, Period = 2.

Since frequency is [tex]\frac{1}{P}[/tex], therefore

Frequency = [tex]\frac{1}{2}[/tex]

The frequency is T / (2π).

To find the frequency of the function f(x) = 3 cos(T x) – 2, start by recognizing the standard form of a cosine function, which is f(x) = A cos(Bx + C) + D. Here, A, B, C, and D are constants with specific roles.

        f = ω / (2π)

        f = T / (2π)

Therefore, the frequency of the function f(x) = 3 cos(Tx) – 2 is T / (2π).

The median is the middle number of the data set so let’s find it!

Step 1. Order your numbers from least to greatest so after we have done that, our numbers would be 2,2,5,10,12,13,18,24

Step 2. We want to cross of a number at the beginning so Starting with 2 and the last number 18 and do that either until we get to one number in the middle or two numbers.

Step 3. There is no one number in the middle but we have the numbers 10 and 12 so we add them together which gives us a sum of 22 and then divide 22 by 2 and we get a quotient of 11.

Our median is 11.
