Write the equation of a line in slope intercept form that is perpendicular to Y= -1/3x+4 and pass through the point (-2,-5)

Answers

Answer 1

Answer:

y = 3x + 1

Step-by-step explanation:

The general form of the slope intercept form is y = mx + b where m is the slope and b is the y-intercept.  

In perpendicular lines, we find the slope of the second equation (m2) using the formula:

[tex]m_{2}=-\frac{1}{m_{1} }[/tex]

Since -1/3 is m1 we have:

[tex]m_{2}=-\frac{1}{-(\frac{1}{3}) } \\ m_{2}=3[/tex]

Now that we've found the slope of the second line, we simply need to find b or its y-intercept by plugging in (-2, -5) and our slope:

[tex]-5=3(-2)+b\\-5=-6+b\\1=b[/tex]

Thus, the equation of the second line is y = 3x + 1

How to evaluate an expression?

In maths, an expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.) .

In other words, an expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations.

A jewelry designer plans to make a triangular pendant out of gold wire. The wire costs​ $31.65 per centimeter. What is the possible range of costs for the​ wire?

The wire can cost more than $____ and less than $____

Answers

The wire used for the triangular pendant can have a cost more than 664.65 USD and less than 791.25 USD.

How to determine the possible lengths of the missing side

In this problem we find the case of a triangle, in which the length of two sides are known and we need to determine the range of costs associated to the set of all possible triangles. This can be derived by the geometric system described in the image attached below. The minimum and the maximum costs of the pendant:

θ = 0°

l = 10.5 cm - 2.5 cm

l = 8 cm

s = 10.5 cm + 8 cm + 2.5 cm

s = 21 cm

C = (31.65 USD / cm) · (21 cm)

C = 664.65 USD

θ = 180°

l = 10.5 cm + 2.5 cm

l = 13 cm

s = 10.5 cm + 2.5 cm + 12.5 cm

Supplementary Angles

Supplementary angles are angles that have a sum of 180 degrees. They are formed on a straight line.

Solving the Question

Looking at the given diagram, we can notice how angle SUV and SUT are supplementary angles. We know this because they form the straight line, VT.

We are given angle SUT, which is 58 degrees.

Because angles SUV and SUT have a sum of 180 degrees, we can solve for angle SUV by subtracting 58 from 180:

180 - 58 = 122

Therefore, angle SUV is 122 degrees.

Answer

122 degrees

Answer:

Angle SUV = 180 - 58

the number of devices a particular manufacturing company can produce is a function of the number of hours spent making the devices. On average, 4 devices are produced each hour. Assume that devices are produced at a constant rate. Write an equation in two variable that describes the number y, as a function of time the company sends making the devices x

Answers

Answer: y = 4x

Step-by-step explanation: The number of devices a company can produce is a function of the number of hours spent making the devices. On average, 4 devices are produced each hour. If we let x represent the number of hours spent making the devices and y represent the number of devices produced, we can write an equation to describe this relationship as follows:

y = 4x

This equation states that the number of devices produced is equal to 4 times the number of hours spent making the devices. For example, if the company spends 10 hours making the devices, the number of devices produced will be 4 * 10 = 40.

Therefore, the equation y = 4x describes the number of devices produced by the company as a function of the number of hours spent making the devices.

A town has a population of 17000 and grows at 3% every year. What will be the
population after 10 years, to the nearest whole number?

Answers

If the population grows 3% every year, then each year's population is 103% of the previous year's population.  This gives us the exponential function:    

        [tex]f(x) = 17000 (1.03)^x[/tex]

17000 for the current population, 1.03 growth factor for the 103%, raised to the x power because we'll need 103% of 103% of 103% and so on until we multiply by 103% for the correct number of years.

[tex]f(10) = 17000(1.03)^{10} \approx 22846.578448850072648[/tex]

Michael went shopping for a new video game because of a sale. The price on the tag was $46, but Michael paid $34.50 before tax. Find the percent discount.

Answers

The discount percentage offered on the new video game as of a sale is 75%.

Explain the term discount percentage?When a product is offered at a discount, the seller is reducing the product's price from what it was originally listed for. The percentage discount just on product is determined by the discount amount stated as a percentage of the initial price.

For the stated question-

The listed price on the video game = $46.

price paid exclusive of tax = $34.50.

Let 'x' be the percentage discount of the listed price.

Then,

x% of 46 = 34.50

x = 34.50 x 100 / 46

x = 75%

(Simplify your answer.)
The maximum height reached by the object is feet.
(Simplify your answer.)"

Answers

The rocket reaches its maximum height at 2.25 second(s) after launch

The maximum height reached by the object is 88 feet.

What is the maximum height the rocket reached?

Given function:

h(t) = -16t² + 72t + 7

By differentiating the function, we have

h'(t) = -32t + 72

Set the function to 0

-32t + 72 = 0

32t = 72

Divide both sides by 32

t = 2.25

Hence, the time is 2.25 seconds

To find the maximum height reached by the rocket,

Substitute t = 2.25 into

h(t) = -16t² + 72t + 7

h(2.25) = -16(2.25)² + 72(2.25) + 7

= -16(5.0625) + 162 + 7

= -81 + 162 + 7

h(2.25) = 88
