4. y= -3x + 5

Answers

Given:

Slope of a line = 3

Line passes through the point = (2,7)

To find:

The equation of the line.

Solution:

The point slope form of a line is:

$y-y_1=m(x-x_1)$

Where, m is the slope of the line.

The line passes through the point (2,7) and slope of the line 3. So, the equation of the line is:

$y-7=3(x-2)$

$y-7=3x-6$

$y=3x-6+7$

$y=3x+1$

Therefore, the correct option is 3.

Mr. Brown is going to start sleeping an extra 30 minutes each night. If d represents the number of days, which of the following expressions shows how many more hours of sleep Mr. Brown will get in a week?

Answers

The additional hours of sleep is an illustration of rates.

The expression that represents the additional hours is d/2

The number of days is given as:

$\mathbf{Days = d}$

The rate of sleep per day is given as:

$\mathbf{Rate =30}$

So, the required expression is:

$\mathbf{Expression = Days \times Rate}$

This gives

$\mathbf{Expression = d \times 30}$

$\mathbf{Expression = 30d}$

Divide by 60, to represent it as hours

$\mathbf{Expression = \frac{30d}{60}}$

$\mathbf{Expression = \frac{d}{2}}$

Write a quadratic function f whose zeros are -4 and -1

Answers

The quadratic function f whose zeros are -4 and -1 is f(x) = x² + 5x + 4.

What is the quadratic function f whose zeros are -4 and -1?

Roots are the points where the graph intercepts with the x-axis, at that point y or f(x) = 0.

Given the roots in the question;

-4 and -1.

x = -4 was found by solving for x when x - (-4) = y or f(x) and we know that y or f(x) = 0

Hence, the factor is

x - (-4) ⇒ ( x + 4 )

x = -1 was found by solving for x when x - (-1) = y or f(x) and we know that y or f(x) = 0

Hence, the factor is

x - (-1) ⇒ ( x + 1 )

Next, we combine the factors and expand;

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

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

f(x) = x² + x + 4x + 4

Combine like terms

f(x) = x² + 5x + 4

Therefore, the quadratic function f whose zeros are -4 and -1 is f(x) = x² + 5x + 4.

The area of the triangle is 47.91 units²

How to find the area of the triangle?

When all three sides of the triangle are known we can use Heron's formula. Consider the triangle ABC with sides a, b, and c has shown in the image.

Heron’s formula is:

Area =√s(s−a)(s−b)(s−c)

where,

a, b, c are the side length of the triangle

s is the semi-perimeter. s = (a+b+c)/2

In this case:

Using the knowledge of the radius of a circle. We can say:

a = BC = 3 + 9 = 12 units

b = AC = 5 + 3 = 8 units

c = AB = 5 + 9 = 14 units

s = (a+b+c)/2

s = (12+8+14)/2

s = 34/2

s = 17 units

Area = √s(s−a)(s−b)(s−c)

Area = √17(17−12)(17−8)(17−14)

Area = √17(5)(9)(3)

Area = √2295

Area = 47.91 units²

The data set for which the mean would be the best measure of center is option b.) 75, 78, 82, 68, 72, 71, 77, 80.

What is mean?

In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.

The mean is a good measure of center when the data is roughly symmetrically distributed, without any extreme values that could skew the average.

Option b) has data that is reasonably distributed around a central value, with no clear outliers or extreme values. Option a) has an extreme value of 90, which could skew the mean higher. Option c) has an extreme low value of 29 that could skew the mean lower. Option d) has extreme values of 84 and 22, which could distort the mean value.

Therefore, the data set for which the mean would be the best measure of center is option b.) 75, 78, 82, 68, 72, 71, 77, 80.

What are the solutions to x³ = -2 – 2i in polar form?

Answers

Therefore, the solutions to x³ = -2 - 2i in polar form are x₁ = √6 + √2i, x₂ = -√2 + √6i, and x₃ = -√6 - √2i.

What is complex number?

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, defined as the square root of -1. The real part of the complex number is a, and the imaginary part is bi. Complex numbers are often used in mathematics and engineering to represent quantities that involve both a real part and an imaginary part, such as electrical impedance, wave functions, and solutions to polynomial equations. Complex numbers can be added, subtracted, multiplied, and divided using rules similar to those for real numbers, and they can be plotted in a two-dimensional coordinate system called the complex plane, with the real part along the x-axis and the imaginary part along the y-axis.

Here,

To find the solutions to the equation x³ = -2 - 2i in polar form, we first convert the complex number -2 - 2i to polar form:

|-2 - 2i| = sqrt((-2)^2 + (-2)^2) = 2*sqrt(2)

arg(-2 - 2i) = tan⁻¹((-2)/(-2)) = tan⁻¹(1) = π/4 (in the second quadrant)

So, -2 - 2i in polar form is 2√2∠(π/4).

Next, we can write x³ in polar form as |x³|∠(3θ), where |x³| = |x|³ and 3θ is the angle formed by rotating θ three times. So we have:

|x³| = |-2 - 2i| = 2*sqrt(2)

3θ = arg(-2 - 2i) + 2kπ, where k is an integer

Substituting the value of arg(-2 - 2i), we have:

3θ = π/4 + 2kπ

Dividing both sides by 3, we get:

θ = π/12 + (2kπ)/3

So the three solutions in polar form are:

x₁ = 2√2∠(π/12)

x₂ = 2√2∠(5π/12)

x₃ = 2√2∠(9π/12)

Simplifying, we have:

x₁ = √6 + √2i

x₂ = -√2 + √6i

x₃ = -√6 - √2i

Answers

The solutions to the questions are

The number we are using is 5The perfect square number closest to the area is 1024The estimated side length is 32

What are areas?

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

The number to use

The area expression is given as

Area = ▢ × 102 + ▢ × 101 + 6

From the question, we can use any number

However, this number must be positive

Assume the number is 5

So, we have

Area = 5 × 102 + 5 × 101 + 6

The perfect square number closest to the result

In (a), we have:

Area = 5 × 102 + 5 × 101 + 6

Evaluate

Area = 1021

The perfect square number closest to this is

Closest = 1024

The estimated side length

In (b), we have

Closest = 1024

Rewrite as

Area = 1024

two alarms are set to go off in the morning. one alarm will buzz every 6 minutes and the other will beep every 9 minutes. if both alarms go off 6:15 am what is the next time the both alarms will go off at the same time

Answers

Answer = 6:33 AM

=========================================================

Explanation:

The LCM of 6 and 9 is 18. We can see that by listing out the multiples

multiples of 6 = {6,12,18,24,30,...}

multiples of 9 = {9,18,27,36,45...}

Or we could multiply 9*6 = 54, and divide by the GCF 3 getting 54/3 = 18. There are a few options to find the LCM.

The LCM being 18 means that every 18 minutes, both alarms will go off. If they both sound off at 6:15 AM, then the next time they trigger together is 6:33 AM since 15+18 = 33, and there is no carry over to the next hour.

You can think of the time values adding like this

6:15 + 0:18 = (6+0):(15+18) = 6:33

The volume of a cone is 13.4m cubed and the radius is 3.2m what is the height

Answers

Answer:

The height is 1.25m.

Step-by-step explanation:

Volume = 1/3 πr²h

Given:

V = 13.4 m³

r = 3.2 m

Asked: height (h)

Substitute the formula with the given values then solve

13.4m³ = 1/3π(3.2m)²h

13.4(3) = 10.24πh

40.2 = 10.24πh

h = 40.2/10.24π

h = 1.25m

The height of the cone is 1.25 meters.

We know that the volume of the cone is given by

V = (1 / 3) * π * r ^2 * h................equation 1

where,

V is the volume of the cone.

r is the radius of the cone's base

h is the height

The volume and radius of the cone are given,

V = 13.4 m

r = 3.2m

substituting these values in equation 1 we get,

13.4 = (1 / 3) * 3.14 * 3.2 ^ 2 * h

on simplifying further

13.4 = 10.717 * h

h = 1.25m

The height of the cone is 1.25 meters.
