Step-by-step explanation:
The line RS has a vertical line running through S. The line has the equation of x = - 1
The line running through R (the origin) has a slope to be determined by the points TS
T=6,0
S=-1,4
m = (y2 - y1) / (x2 - x1)
m = (4 - 0)/(-1 - 6)
m = 4/-7
The line you want going through 0,0 has a slope of m1 * m2 = -1 where m1 = -4/7
-4/7 * m2 = - 1
m2 = -1/(-4/7) = 7/4
Since the line goes through 0,0 the equation is y = 7/4 x
====================
The orthocenter must be on a y value determined by x = - 1
The orthocenter is (-1,-7/4)
y = 4/7
The orthocenter is (-1,4/7)

The price of an item in a shopping cart is c dollars. If the sales tax on the item is 9%, and the expression c + 0.09c represents the total cost of the item after tax, which TWO EXPRESSIONS also represent the total cost of the item after tax?
A) 0.9c
B) 1.09c
C) 1.9c
D) (1 – 0.09)c
E) (1 + 0.09)c
Answers
If you factor c + 0.09c, we get c(1 + 0.09), which is the same as (1 + 0.09)c.
If we add the numbers inside the parentheses (1 + 0.09)c we get 1.09c.

Consider the equation 3a+0.1n=123. If we solve this equation for n, which equation would result? A. 0.1n=123-3a B. N=123-3a-0.1 C.N=1,230-30a D. 3a-123 over 0.1 =n
Answers
Answer:
n = (123 - 3a) / 0.1
Step-by-step explanation:
Given:
3a + 0.1n = 123
Solve for n
3a + 0.1n = 123
Subtract 3a from both sides
3a + 0.1n - 3a = 123 - 3a
0.1n = 123 - 3a
Divide both sides by 0.1
n = (123 - 3a) / 0.1
The resulting equation if 3a + 0.1n = 123 is solved for n is n = (123 - 3a) / 0.1

Complete Question
On a two week job, a repairman works a total of 70 hours. He charges $75 plus $40 per hour. An equation shows the relationship where x is the number of hours and y is the total fee. Write the equation. What is the slope and y-intercept?
Answer:
a)Write the equation.
y = 40x + 75
b) What is the slope and y-intercept?
The slope = 40
y - Intercept = 75
Step-by-step explanation:
On a two week job a repairman works a total of 70 hours. He charges 75$ plus 40$ per hour.
The equation shows this realationship where x is the number of hours and y is the total fee is given using the equation of a straight line which is given as:
y = mx + c
Where m = Slope
c = y intercept
Applying this equation to our question , we have:
y= 40x + 75
The slope = m = 40
y-intercept = c = 75
Answer:
75 y intercept.

Step-by-step explanation:
Calculate the values of y by substituting the values of x into y = - 6x + 2
x = - 5 → y = - 6(- 5) + 2 = 30 + 2 = 32
x = - 1 → y = - 6(- 1) + 2 = 6 + 2 = 8
x = 0 → y = - 6(0) + 2 = 0 + 2 = 2
x = 1 → y = - 6(1) + 2 = - 6 + 2 = - 4
Thus
x y

- 1 8
0 2
1 - 4
Answer:
32
8
2
-4
Step-by-step explanation:
The question is asking you to fill in the table for each value of x. That might sound a little confusing at first... but it's simpler than you think.
The equation y = -6x + 2 is important for the entire problem. What the equation means... is that (-6 times x) + 2 equals y. What does that mean? Let's take a look.
In this equation, x and y are variables. That means that they can be any number... for now they are just holding the place of any number. For example... x + 2 = 4. In this equation... x has to be 2. The same idea is being applied here.
If you want to find what "y" is equal to... you have to replace "x" with the number that the table gives you.
For example... the table asks us to find "y" when "x" is -5.
y = -6 (-5) + 2
y = 30 + 2
y = 32
(It's important to remember that if you multiply two negative numbers... you get a positive product.)
Repeat this process for all of the other values they ask for "x" to get an answer for "y"

What is the weight of the seawater in an aquarium that is 4.4 ft long, 2.5 ft wide, and 5.3 ft high?
Answers
Answer:
The weight of the sea water in the aquarium is 3827.119 lb
Step-by-step explanation:
We start by calculating the volume of the aquarium
Since it is a cuboid, the volume will be L * B * H
= 4.4 * 2.5 * 5.3 = 58.3 ft^3
Mathematically;
Mass = density * volume
The density of sea water is 63.93 lb/ft^3
Mass = 63,93 * 58.3 = 3,827.119 lb
In the year 2000, the United States had about 100,300,000 people registered to use cellular phones. How would this number of people be written in scientific notation?
Answers
Answer:
1.003 * 10^8
Step-by-step explanation:
Given that :
The United States has about 100,300,000 registered to use cellular phones in the year 2000
100,300,000 in scientific notation:
(100,000,000) + (300,000)
(1 * 10^8) + (3 * 10^5)
To ensure equal power :
300,000 = 3 * 10^5 = 0.003 * 10^8
Hence,
(1 * 10^8) + (0.003 * 10^8)
(1 + 0.003) * 10^8
1.003 * 10^8

deposits of 1000 are made into the accounts of each type. no additional Including
withdraws or deposits are made.
what amount is the closest to the interest earned in 5 years.
Answers
Answer:
(a) The closet to the simple interest eaened in 5 years is $275.00.
(b) The closet to the compound interest earned in 5 years is $276.28.
Step-by-step explanation:
These can be determine as follows:
(a) Simple Interest
The interest earned and be determined using the simple interest formula as follows:
Simple interest = P * R * T ....................... (1)
Where;
P = Principal = $1,000
R = interest rate = 5.5%
T = term = 5
Substituting the values into equation (1), we have:
Simple interest = $1,000 * 5.5% * 5 = $275.00
(b) Compound Interest
The interest earned and be determined using the compound interest formula as follows:
Compound interest = P(1 + R)^T - P ....................... (2)
Where;
P = Principal = $1,000
R = interest rate = 5%, or 0.05
T = term = 5
Substituting the values into equation (2), we have:
Compound interest = $1,000(1 + 0.05)^5 - $1,000 = ($1,000 * 1.05^5) - $1,000 = ($1,000 * 1.2762815625) - $1,000 =$1,276.28 - $1,000 = $276.28
Interest earned in savings Account 1 = 275
Interest earned in savings Account 2= 276.282
What is the difference between simple interest and compound interest?Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.
interest earned by savings account 1
I₁=P*R*T/100
where,
P= Principal
R= rate of simple interest
T = time
I₁=1000*5.5*5/100
compound interest I₁=275
Interest earned by savings account2
amount A after n years= [tex]P(1+\frac{r}{100} )^n[/tex]
where,
A= amount received after 5 years
P= principal
r = rate(compound annually)
n = time
[tex]A = 1000(1+\frac{5}{100} )^5\\\\A=1276.282[/tex]
Compound interest I₂ = 1276.282-1000=276.282
Therefore,
interest earned in savings Account 1 = 275
interest earned in savings Account 2= 276.282

The cross section (with
units in inches) of a parabolic satellite dish can be modeled by the equation y=1/38 x^2
How far is the
receiver from the vertex of the cross section? Explain.
Answers
Answer:
9.5 in
Step-by-step explanation:
The receiver is placed at the focus of the parabola at a distance of 1/4a from the vertex. Here that would be 1/(4*(1/38)) or 38/4 inches or 9.5 in
The receiver lies 9.5 inches far from the vertex of the cross-section.
Given that,
The cross-section (with units in inches) of a parabolic satellite dish can be modeled by the equation y=1/38 x².
To determine how far is the receiver from the vertex of the cross-section.
A parabola is a cross-section cut out of the cone and represented by an equation, y =4ax².
Here,
The receiver is located near the parabola's focus, 1/4a away from the vertex. That would be 1/(4×(1/38)) or 38/4 inches or 9.5 in. in this case.
Thus, the receiver lies 9.5 inches far from the vertex of the cross-section.
