Answer:
3.5
Step-by-step explanation:
Given points are ,
G(-2,3) H (5,1)Firstly find the slope of the line passing through these two points . Therefore ,
=> m = y₁ - y₂ / x₁ - x ₂
=> m = ( 3 - 1)/(-2-5)
=> m = -2/7
The slope of line perpendicular to it will be negative of reciprocal of the slope . Let m' be the slope of perpendicular line .=> m' = -1/m
=> m' = -1 ÷ -2/7
=> m' = -1 × -7/2
=> m' = 7/2 = 3.5
Hence the slope of the line perpendicular to the given line is 3.5 .Find the volume of the cone. Round your answer to the nearest hundredth.

Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences.
Answer:
Tessa is correct. They have enough money.

Find the argument of the complex number z=1+iv3
Given:
The complex number is:
[tex]z=1+i\sqrt{3}[/tex]
To find:
The argument of the given complex number.
Solution:
If a complex number is [tex]z=x+iy[/tex], then the argument of the complex number is:
[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]
We have,
[tex]z=1+i\sqrt{3}[/tex]
Here, [tex]x=1[/tex] and [tex]y=\sqrt{3}[/tex]. So, the argument of the given complex number is:
[tex]\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}[/tex]
[tex]\theta =\tan^{-1}\sqrt{3}[/tex]
[tex]\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)[/tex]
[tex]\theta =\dfrac{\pi}{3}[/tex]
Therefore, the argument of the given complex number is [tex]\theta =\dfrac{\pi}{3}[/tex].
if cos theta = 3/5 and theta is in quadrant 4, tan 2 theta =
Answer:
16/9.
Step-by-step explanation:
I am assuming you mean tan^2 theta.
The adjacent side of the triangle drawn in Q 4 = 3 (as cos theta = 3/5.
The opposite side of the triangle drawn in Q 4 = sqrt(5^2-3^2) = 4.
The tangent is negative in Q 4
So tan theta = -4/3.
tan^2 theta = 16/9.

The volume of the square prism is one third the volume of the cylinder.
The volume of the square prism is half the volume of the cylinder.
The volume of the square prism is equal to the volume of the cylinder.
The volume of the square prism is twice the volume of the cylinder.
Answer:
The volume of the square prism is equal to the volume of the cylinder.
Step-by-step explanation:
As per the information depicted the volume of the square prism is equal all to the volume of the cylinder. Hence option C is correct.
What is the square prism?A square prism is thee dimensional cuboid with a base and the top has an equal square while the remaining four faces have a rectangle and the opposite side angles of the square prism are congruent and parallel to each other.
As a square prism have the least two lengths that are equal to each other. Hence the volume of the square prism is equal to the volume of the cylinder as they have the same height and area of cross-section.

What are the intercepts of y = 4x − 2?
A. (2, 0) and (0, 0.5) B. (2, 0) and (0, 5) C. (2, 0) and (0, -2) D. (0.5, 0) and (0, -2)
Answer:
D. (0.5, 0) and (0, -2)
Step-by-step explanation:
We have the following equation:
[tex]y = 4x - 2[/tex]
x-intercept:
The x-intercept of an equation is the value of x when [tex]y = 0[/tex]. So
[tex]y = 0[/tex]
[tex]4x - 2 = 0[/tex]
[tex]4x = 2[/tex]
[tex]x = \frac{2}{4}[/tex]
[tex]x = 0.5[/tex]
So (0.5,0) is one of the intercepts
y-intercept:
The y-intercept of an equation is the value of y when [tex]x = 0[/tex]. So
[tex]y(0) = 4(0) - 2 = 0 - 2 = -2[/tex]
So (0, -2) is the other intercept.
The correct answer is given by option D.
Solve for V . 7v-20=-6(v-1) Simplify your answer as much as possible.
Answer:
v = 2
Step-by-step explanation:
You can start by distributing -6:
7v - 20 = -6v + 6
To combine the like x terms, you can add 6v to both sides:
7v - 20 = -6v + 6
+6v +6v
13v - 20 = 6
Now add 20 to both sides to isolate the x term:
13v - 20 = 6
+20 +20
13v = 26
You can divide by 13 on both sides to find v,
13v = 26
÷13 ÷13
v = 2
Answer:
v= 2
Step 1: Simplify both sides of the equation.
7v−20=−6(v−1)
7v+−20=−6v+6
7v−20=−6v+6
Step 2: Add 6v to both sides.
7v−20+6v=−6v+6+6v
13v−20=6
Step 3: Add 20 to both sides.
13v−20+20=6+20
13v=26
Step 4: Divide both sides by 13.
13v/13 = 26/13
v=2

no solution
infinite solutions
Answer:
infinitely many solutions
Step-by-step explanation:
solve by substitution:
solve equation 1 for y: - y = 7 - 4x; divide by -1 to simplify into y = -7 + 4x
Substitute - 7 + 4x into the second equation to obtain:
3(-7 + 4x) - 12x = -21, which yields:
-21 + 12x - 12x = -21, which simplifies 0 = 0
a result of 0 = 0 means infinite solutions such as:

The probability of spinning a yellow is 1/4.
The probability of spinning an odd number is 1/2.
The probability of spinning a number less than 5 is 1/2.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
From the spinner
Blue region = 3
Red region= 1
Yellow region = 2
Purple region = 2
So, the probability of getting Yellow
P (spinning yellow) = 2 / 8
= 1 / 4
and, the probability of getting odd number
P (Spinning an odd number) = 4 / 8
= 1 / 2
and, the probability of getting less than 5
P ( spinning a number less than 5) = 4 / 8
= 1 / 2

Answer:
The population density of India in 2016 was of 1042.8 habitants per miles squared.
Step-by-step explanation:
Population density:
Number of habitants divided by land area.
In 2010 the population of India was 1,231,000,000. By 2016, the population had increased by 7.5%.
This means that India's population in 2016 was given by:
1,231,000,000*1.075 = 1,323,325,000
The land area of India is 1, 269,000 miles squared:
1,323,325,000/1,269,000 = 1042.8 habitants per miles squared.
The population density of India in 2016 was of 1042.8 habitants per miles squared.
