Answer:

4y = x + 7.

Step-by-step explanation:

The slope of a line perpendicular to a line of slope m = -1/m

So the slope of the required line = -1/ (-4) = 1/4.

y - y1 = m(x - x1)

y - 2 = 1/4(x - 1)

y = 1/4(x - 1) + 2

y =  1/4x - 1/4 + 2

y = 1/4x + 7/4

4y = x + 7

the cost of hiring Nicole for any number of hours "h" will be $15 plus $5 multiplied by the number of hours you hire her for.

To find the cost of hiring Nicole for any number of hours, you need to know the hourly rate and add it to the initial fee.

According to the problem, Nicole charges an initial fee of $15 and $5 per hour. So if you hire Nicole for "h" hours, the cost will be:

Cost = Initial fee + Hourly rate x Number of hours

Cost = $15 + $5 x h

Therefore, the cost of hiring Nicole for any number of hours "h" will be $15 plus $5 multiplied by the number of hours you hire her for.

1) In the set of triangles given, x = 48ft. The triangle are similar because the ratio of each side to the others are the same that is - 5:3
2) In this case, x = 16ft.
The Ratio is 1:1, thus they are similar.

1)

a )To solve for x, we must state that:

50/30 = 80/x

To solve for x in the equation:

50/30 = 80/x

You can begin by cross-multiplying the fractions. That means multiplying the numerator of the first fraction by the denominator of the second fraction, and vice versa. This gives:

50x = 30 * 80

Simplifying the right-hand side of the equation:

50x = 2400

Now, to solve for x, you can divide both sides of the equation by 50:

x = 2400/50

Simplifying this expression:

x = 48

Therefore, x is equal to 48.

b) The ratio is the comparison of two quantities. In this case, the ratio can be found by simplifying the fractions on both sides of the equation:

50/30 = 5/3

80/48 = 5/3 (by dividing both numerator and denominator by 16)

Therefore, the ratio is 5:3, which means that the two quantities being compared are in the ratio of 5 to 3.

2)

a) To solve for x, we must state that:

if 6/4.5 = x/12

To solve for x in the equation:

6 / 4.5 = x / 12
6 * 12 = 4.5 * x
x = (6 * 12) / 4.5
x = 72 / 4.5

x = 16

b)

To justify that both triangles are similar, we must look at the ratio of their sides.


The ratio between the first fraction 6/4.5 and the second fraction 16/12 can be found by simplifying both fractions to their lowest terms and then comparing the resulting values.

To simplify 6/4.5, we can divide both the numerator and denominator by their greatest common factor, which is 1.

6/4.5 = (6 ÷ 1)/(4.5 ÷ 1) = 6/4.5

To simplify 16/12, we can divide both the numerator and denominator by their greatest common factor, which is 4.

So the simplified ratio between the two fractions is:

6/4.5 : 16/12

= 6/4.5 : 4/3

To compare these ratios, we can cross-multiply to get:

(6 * 3) : (4.5 * 4) = 18 : 18 = 1 : 1

Therefore, the ratio between 6/4.5 and 16/12 is 1:1 or simply 1.

This means the two triangles are similar.

The answer of the given question based on the right angle triangle is , the height of the light pole to the nearest tenth of a foot is 9.3 feet.

A right-angled triangle, also known as a right triangle, is a triangle that has one angle equal to 90 degrees. The side opposite right angle is called hypotenuse, and other two sides is called legs. The leg opposite to a particular acute angle is known as the opposite side, and the leg adjacent to it is known as the adjacent side.

The Pythagorean theorem is a fundamental theorem that applies to all right-angled triangles. It states that square of hypotenuse of right-angled triangle is equal to sum of squares of its two legs

To determine the height of the light pole, we can use similar triangles.

Let's call height of light pole be  "x". Then we have:

(height of stop sign) / (length of stop sign's shadow) = (height of light pole)/(length of light pole's shadow)

Substituting the given values, we have:

8/12 = x/14

Simplifying this equation, we get:

x = (8/12) * 14 = 9.33 feet

Therefore, the height of the light pole to the nearest tenth of a foot is 9.3 feet.

The probability of getting two heads and one tail in any order is 3/8.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. For example, the probability of flipping a coin and it landing heads up is 0.5, because there are two equally likely outcomes (heads or tails) and one of them is heads.

Probabilities can also be expressed as percentages or fractions. For instance, a probability of 0.25 can be expressed as a percentage of 25%, or as a fraction of 1/4.

According to the question:
The sample space for flipping three coins is:
HHH

HHT

HTH

THH

HTT

THT

TTH

TTT

where H represents heads and T represents tails.

Out of these eight outcomes, there are three outcomes in which two heads and one tail come up in any order: HHT, HTH, and THH. Therefore, the probability of getting two heads and one tail in any order is 3/8, or 0.375, which can also be written as a fraction.

To see why this is the case, you can also use a tree diagram to represent the sample space:
     H              T

   /   \          /   \

  H     T        H     T

 / \   / \      / \   / \

H   T H   T    H   T H   T

Each branch represents the outcome of one coin flip, and the branches lead to the possible outcomes of flipping three coins. The outcomes with two heads and one tail are HHT, HTH, and THH, which occur in three out of the eight possible outcomes, as previously stated. Therefore, the probability of getting two heads and one tail in any order is 3/8.

To solve this system of equations graphically, we need to plot the lines represented by each equation on a coordinate plane and find their intersection point (if it exists).

First, let's rearrange the first equation to solve for y:

[tex]y = (2/3)x + 4[/tex]

Now, we can plot this line by finding two points on it. For example, when x = 0, y = 4, and when x = 3, y = 6. We can then connect these points with a straight line.

[tex]y < 4x[/tex]. This is an inequality, so we'll shade the region below the line y = 4x. To plot the line itself, we can again find two points on it. When x = 0, y = 0, and when x = 1, y = 4. Connecting these points.

we need to shade the region below this line, since y is less than 4x. This region includes all points on the coordinate plane that satisfy y < 4x. We can shade it by drawing a dotted line along the line y = 4x and shading the region below.

From the following option given, the correct option is option (3) - detect assignable cause variations versus normal random variations in the process.

The objective of statistical process control (SPC) is to monitor and control a process to ensure that it operates within its specifications and meets the desired quality level. One of the main goals of SPC is to distinguish between normal random variation in the process and variation that is caused by assignable or special causes.

By identifying and eliminating the assignable causes of variation, the process can be improved and the quality of the output can be maintained or improved over time. Therefore, the primary objective of SPC is to detect assignable cause variations versus normal random variations in the process.

Options 1, 2, and 4 are related to quality control and monitoring, but they do not capture the essence of what SPC is trying to achieve.

Therefore, the rate/slope between the two given points is 60.

In mathematics, slope refers to the steepness or incline of a line. It measures how much a line rises or falls over a certain horizontal distance, which is called the "run." Slope is usually denoted by the letter m and is defined as the ratio of the change in y (the vertical distance) to the change in x (the horizontal distance) between any two points on the line.

Here,

1. To find the rate/slope between the coordinates (1,60) and (2,120), we can use the slope formula:

slope = (change in y) / (change in x)

So, we have:

slope = (120 - 60) / (2 - 1)

= 60 / 1

= 60

2. The equation given is y = 65x, where x is the time in hours and y is the number of miles. To find the rate/slope, we can see that the equation is in the form of y = mx, where m is the slope. So, the slope of this equation is 65. Therefore, the rate/slope for the given equation is 65.

The magnitude of a vector is the length of the vector. For a vector that passes from the origin to the point (6,2),

the magnitude can be calculated using the Pythagorean theorem, which states that for a right triangle with legs of length a and b and hypotenuse of length c,

c² = a² + b².

In this case, the vector is the hypotenuse of a right triangle with legs of length 6 and 2, so the magnitude is:

magnitude = √(6² + 2²) = √(40) = 2*√(10)

The direction angle of a vector is the angle that the vector makes with the positive x-axis, measured counterclockwise. The direction angle can be calculated using the inverse tangent function, which is the inverse of the tangent function. In this case, the direction angle is:

direction angle = tan⁻¹(2/6) = tan⁻¹(1/3)

Therefore, the correct answer is: √(6² + 2²), and tan⁻¹(2/6) represents the magnitude and direction angle of the vector.

The value of the computer after 5 years is $189.84 and [tex]v = 800 * (3/4)^t[/tex] , where v is the value of the computer t years after it is purchased.

1. The computer costs $800 initially and loses 1/4 or 25% of its value every year. We can represent this decrease in value using the following formula:

[tex]v = 800 * (1 - 1/4)^t[/tex]

where v is the value of the computer t years after it is purchased. Simplifying this equation, we get:

[tex]v = 800 * (3/4)^t[/tex]

2. To find the value of the computer when t is 5, we can substitute t = 5 into the equation we derived in step 1:

[tex]v = 800 * (3/4)^5[/tex]

[tex]v = 800 * 0.2373[/tex]

[tex]v = 189.84[/tex]

This means that the value of the computer after 5 years is $189.84. This value is less than the initial cost of the computer, which was $800. It indicates that the computer has significantly depreciated in value over time, losing approximately 76% of its initial value.

2. Use your equation to find v when t is 5. What does this value of v mean?

Answer:

1and 2/3

Step-by-step explanation:

using the factorization method

the product of the equation is positive 6(3×2)

then we find the factors of 6 which give us the product 6 and the sum of-5

the factors are-3 and -2

we then substitute negative 5 with these factors

it then be 3x^2-3x-2x+2=0

then we group factorise

we will have 3x(x-1)-2(x-1)=0

we find the common factors of the 2 groups

we will then have (x-1)(3x-2)=0

then we equate the both brackets to 0

(x-1)=0 and(3x-2)=0

for the first bracket add 1 both sidesand the second add 2 both sides and divide by 3
