Answer:
(637.50 - 200) / 17.50 = h
h = hours worked
Step-by-step explanation:
If you do (637.50 - 200) that will get you 437.5 which you just divide by 17.50 which gets you the amount of hours he worked (25)
Simon put $15000 in an account with a simple interest rate of 4.5%. How much interest will be earned after 8 years?
Answer:
The interest earned at the end of 8 years is $5400, hope this helps!
Step-by-step explanation:
The interest earned at the end of 8 years is $5400.The fee you pay to borrow money or the fee you charge to lend money is called interest.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.
It is given that, Simon put $15000 in an account with a simple interest rate of 4.5% for the time period of 8 years.
Principal,P = $15000
Rate,R = 4.5% per annum
Time period, T =8 years
The simple interest is found as,
SI = (P×R×T) / 100
Where P is the principal, T is the rate and T is the period.
SI = ( $15000×4.5× 8 ) / 100
SI = $540000/100
SI = = $5400
Thus, the interest earned at the end of 8 years is $5400.

How would I do this?
Answer: 68 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
Since we are given 2 of the angles, we can set up an equation.
Let the measure of angle G = g.
Then, g + 97 + 15 = 180
g + 112 = 180
g = 68
Answer:
68°
Step-by-step explanation:
All triangles add up to 180°, so you would simply do:
97° + 15°
= 112°
And then:
180° - 112°
= 68°

Jason is bungee jumping in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function y = x² - 18x, where x is the time in seconds and y is the height in feet.
A) How long did it take for Jason to reach his minimum height?
B) What was the lowest point that Jason reached?
C) Jason returned to the top of the bungee jump at what time?
Answer:
A) 9 seconds
B) lowest point is -81 ft, or 81 ft below the top of the bungee jump
C) 18 seconds
Step-by-step explanation:
A) To find the x-value of the turning point (minima/maxima) differentiate, then set to zero and solve for x:
[tex]\dfrac{dy}{dx}=2x-18\\\\\implies \dfrac{dy}{dx}=0\\\\\implies 2x-18=0\\\\\implies x=9[/tex]
Therefore, it took 9 seconds to reach the minimum height
B) lowest point is when x = 9:
⇒ y = (9)² -18(9) = -81
Therefore, lowest point is -81 ft, or 81 ft below the top of the bungee jump
C) find x when y = 0
⇒ x² - 18x = 0
⇒ x(x - 18) = 0
⇒ x = 0 and x - 18 = 0
⇒ x = 0 and x = 18
So he returned to the top of the bungee jump at 18 seconds
Answer:
A) 9 s
B) -81 feet
C) 18 feet
step by step explanation:
A)
[tex]\sf y = x^2 - 18x[/tex]
use the vertex formula: [tex]\sf \frac{-b}{2a}[/tex]
Here a = -18 and a = 1, these are coefficients from ax² + bx + x
solve:
[tex]\hookrightarrow \sf \frac{--18}{2(1)}[/tex]
[tex]\hookrightarrow \sf \frac{18}{2}[/tex]
[tex]\hookrightarrow \sf 9[/tex] s
It takes 9 s for Jason to reach his minimum height.
B)
if taken 9 s then put it in x and find the height reached
[tex]\sf \hookrightarrow \sf h(9) = 9^2 - 18(9)[/tex]
[tex]\sf \hookrightarrow h(9) = 81 - 162[/tex]
[tex]\hookrightarrow \sf h(9) = -81[/tex]
The lowest point is - 81 feet, as it says lowest.
C)
solve for when the height, y is 0
[tex]\hookrightarrow \sf 0 = x^2 -18x[/tex]
[tex]\hookrightarrow \sf 0 = x(x -18)[/tex]
[tex]\hookrightarrow \sf x = 0, \ x -18 = 0[/tex]
[tex]\hookrightarrow \sf x = 0, \ x = 18[/tex]
[tex]\hookrightarrow \sf\ x = 18[/tex]
Jason returned to the top of the bungee jump at 18 s.

ADB= $241.66
B) Liam's Monthly Periodic Rate (MPR) is the Annual Interest Rate divided by the number of periods. In this case, that will be:
19.8%/12
MPR = 1.65%
C) Liam's Finance Charge is (Average Daily Balance * APR)/365.
That is (241.66 * 19.8)/365 = 13.11%
D) Liam's New Balance is calculated by removing new inflow from old balance. That is
(250+87.60+1,300+470.63+34.76+102.71+45+848.60)-3,240.5
= $-101.20

Can anyone help with this?
Answer:
Question i)
If y = 4x² - 4x - 1
and 4x² - 4x - 1 = 0
then y = 0
Therefore, we need to find the points on the curve where y = 0.
From inspection of the graph these are approximately when x = -0.25 and x = 1.25
So estimates of the solutions are (-0.25, 0) and (1.25, 0)
Question ii)
If y = 4x² - 4x - 1
and 4x² - 4x - 1 = 2
then y = 2
Therefore, we need to find the points on the curve where y = 2.
From inspection of the graph these are approximately when x = -0.5 and x = 1.5
So estimates of the solutions are (-0.5, 2) and (1.5, 2)

Answer:
Melody added 12 to both sides when she should've subtracted 12 from both sides.
X = 19
Step-by-step explanation:
When solving equations, you have to do the opposite operation given on both sides of the equation. In this case, the operation that's happening is addition, so we have to subtract 12 from both sides.
Step 1: Subtract 12 from both sides.

Give an example of a line which passes through only two quadrants.
Answer:
See below
Step-by-step explanation:
A line that passes only two quadrants must have either 0 slope or undefined slope.
An example of a line with 0 slope is the equation y=5 since there's just a constant and there is no change in y as x changes.
An example of a line with an undefined slope is the equation x=3 since there's just a constant and there is no change in x as y changes, but the change in y divided by the change in x is undefined.
round off 3291 to the nearest 100

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
In this case, Rule A applies and 3291 rounded to the nearest hundred is:

The lengths JL and PM are the lengths that make up the triangle JMP
The length of JL is 78 unitsThe length of PM is 47.5 unitsThe measure of angle MLK is 105 degreesHow to calculate side length JL?The side length JL is twice the side length PN.
So, we have:
JL = 2 * PN
This gives
JL = 2 * 39
JL = 78
Hence, the length of JL is 78 units
How to calculate side length PM?The side length PM is half the side length KL.
So, we have:
PM = 0.5 * KL
This gives
PM = 0.5 * 95
PM = 47.5
Hence, the length of PM is 47.5 units
How to calculate angle MLK?The angle MLK is congruent to the angle JMP.
So, we have:
MLK = JMP
This gives
MLK = 105 degrees
Hence, the measure of angle MLK is 105 degrees

Suppose t and u are linear transformations from to such that t(ux)x for all x in. Is it true that u(tx)x for all x in ? why or why not?.
A linear transformation is used to illustrate a linear operator
It is true that U(T(x)) = x for all values of x
How to determine if the linear transformation is trueThe linear functions are given as:
U(x1) and U(x2)
Given that the function U(x) is a one-one-one function, then we have:
T(U(x1)) = T(U(x2))
This becomes
x1 = x2
The above equations mean that the function U is invertible
So, we have:
S(U(x)) = U(S(x)) = x for all values of x
Also, we have:
T(U(x)) = x for all values of x.
This means that,
T(x) = S(x) and U(T(x)) = x for all values of x, because U(S(x)) = x for all values of x
Hence, it is true that U(T(x)) = x for all values of x
