The length if a photograph is 6 inches less than twice the width. The photograph is mounted in a frame that is 3 inches wide on all sides. If the area of the framed picture is 270 square inches, find the dimensions of the unframed photograph.
Answer:
see below
Step-by-step explanation:
L = 2W-6
given: (L+3)*(W+3) = 270
so (2W-6+6)*(W+6) = 270
so 2W*(W+6) = 270
open up the brackets
2w²+12W = 270
so solve quadratic equations of 2w²+12W - 270 =0
w = 9 or -15
so dimensions of the unframed photograph = width 9, length 12

A police car is located 40 feet to the side of a straight road.
A red car is driving along the road in the direction of the police car and is 140 feet up the road from the location of the police car. The police radar reads that the distance between the police car and the red car is decreasing at a rate of 85 feet per second. How fast is the red car actually traveling along the road?
The actual speed (along the road) of the red car is feet per second
The actual speed (along the road) of the red car is 8.37 feet per second
To solve this problem
Let's call the distance between the police car and the red car "x" at time t. Then, we know that:
x^2 = 40^2 + (140 - vt)^2
Where
v is the velocity of the red car (in feet per second) t is timeWe are given that dx/dt (the rate at which x is decreasing) is -85 ft/s, so:
d/dt [x^2] = d/dt [40^2 + (140 - vt)^2]
2x(dx/dt) = 0 - 2v(140 - vt)
Substituting dx/dt = -85 and solving for v, we get:
2x(−85) = −2v(140−vt)
−170x = −280v + 2v^2t
v^2t = 140v - (85/2)x
Now, we can differentiate the equation x^2 = 40^2 + (140 - vt)^2 with respect to time to get:
2x(dx/dt) = 2(140 - vt)(-v)
Substituting dx/dt = -85 and solving for x, we get:
-170x = -2v(140 - vt)
x = (140v - vt^2)/85
Substituting this expression for x into the equation we derived earlier, we get:
v^2t = 140v - (85/2)((140v - vt^2)/85)
v^2t = 140v - 70(2v - t^2)
v^2t = 140v - 140v + 70t^2
v^2t = 70t^2
v = sqrt(70t^2)/t = sqrt(70) = 8.37 ft/s (rounded to two decimal places)
Therefore, the actual speed (along the road) of the red car is 8.37 feet per second

Line t has equation y = -x - 2. Find the distance between l and the point D(-7, 0).
Round your answer to the nearest tenth.
the distance between line t and point D(-7, 0) is approximately 3.5 units.
what is distance ?
Distance is a measure of the amount of space between two objects or points. It is usually measured in units such as meters, kilometers, miles, or feet. Distance can be either a scalar quantity
In the given question,
To find the distance between line t and point D(-7, 0), we need to first find the point on line t that is closest to point D.
We can use the formula for the distance between a point and a line in the coordinate plane:
distance = |Ax + By + C| / √(A^2 + B^2)
where Ax + By + C is the equation of the line in standard form, and (x, y) is the coordinates of the point.
In this case, the equation of line t is y = -x - 2, which we can rewrite in standard form as x + y + 2 = 0.
Using the formula above, we have:
distance = |x + y + 2| / √(1^2 + (-1)^2)
distance = |(-7) + 0 + 2| / √(2)
distance = 5 / √(2)
distance ≈ 3.5 (rounded to the nearest tenth)
Therefore, the distance between line t and point D(-7, 0) is approximately 3.5 units.

15 postcards, 10 envelopes, and a notepad cost 1 dollar and 68 cents. The envelope is 8 times cheaper than the notepad and 2 cents more expensive than the postcard. What is the price of the postcard, the envelope, and the notepad?
Let's start by setting up some equations to represent the given information.
Let's say the price of a postcard is "x" cents.
Then, according to the problem statement, the price of an envelope is 8 times cheaper than the notepad, which means the price of an envelope is (1/8)th of the price of the notepad. So the price of an envelope is (1/8)*y cents, where "y" is the price of the notepad in cents.
Also, we know that the price of an envelope is 2 cents more expensive than the price of a postcard, so we can write:
(1/8)*y = x + 2 ...(Equation 1)
We also know that there are 15 postcards and 10 envelopes in the purchase, so the total cost of the postcards and envelopes is:
15x + 10[(1/8)*y] ...(Equation 2)
Finally, we have a notepad that costs "y" cents. So the total cost of the purchase is:
15x + 10[(1/8)*y] + y ...(Equation 3)
We are given that the total cost of the purchase is 1 dollar and 68 cents, which is equal to 168 cents. So we can write:
15x + 10[(1/8)*y] + y = 168 ...(Equation 4)
Now we have four equations (Equation 1, Equation 2, Equation 3, and Equation 4) with three variables (x, y, and 168). We can solve for x and y by using a system of equations.
From Equation 1, we can solve for y in terms of x:
(1/8)*y = x + 2
y = 8x + 16
Substituting this expression for y into Equations 2 and 3, we get:
15x + 10[(1/8)*y] = 15x + 10(8x + 16) = 160x + 160
15x + 10[(1/8)*y] + y = 15x + 8x + 16 = 23x + 16
Substituting these expressions into Equation 4, we get:
23x + 16 = 168
Solving for x, we get:
x = 6
Substituting this value for x into Equation 1, we can solve for y:
(1/8)*y = x + 2 = 6 + 2 = 8
y = 64
So the price of a postcard is 6 cents, the price of an envelope is (1/8)*64 + 2 = 10 cents, and the price of a notepad is 64 cents

Evaluate the expression shown below and write your answer as a fraction. -5/9 -(-9/4)
Step-by-step explanation:
When we simplify the expression -5/9 - (-9/4), we can rewrite it as:
-5/9 + 9/4
To add these fractions, we need to find a common denominator. The least common multiple of 9 and 4 is 36, so we can convert both fractions to have a denominator of 36:
-5/9 = -20/36
9/4 = 81/36
Now we can substitute these values into our expression and add them:
-20/36 + 81/36 = 61/36
Therefore, the simplified expression is 61/36.

Find the equation of a line parallel to 5x+y=5 that passes through the point (8,-9)
Answer:
y = -5x + 31
Step-by-step explanation:
To find the equation of a line parallel to the line 5x + y = 5, we first need to rearrange it in slope-intercept form, which is
y = -5x + 5. (We see that the slope of this line is -5)
A line parallel to this line will have the same slope of -5. Now, we need to find the equation of a line that passes through the point (8,-9) with slope -5.
We can use the point-slope form of the line to find the equation. The point-slope form of a line is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
Substituting the values we have, we get:
y - (-9) = -5(x - 8)
Simplifying this equation, we get:
y + 9 = -5x + 40
y = -5x + 31
Therefore, the equation of the line parallel to 5x + y = 5 that passes through the point (8, -9) is y = -5x + 31.
Carmine takes a loan for $11,500 at a rate of 8% that is compounded quarterly. Assuming she makes no payments for the first 2 years, what is her loan balance?
Carmine's loan balance after two years would be approximately $13,827.72.
Define the term loan?In mathematics, the term "loan" typically refers to a sum of money that is borrowed by one party from another with the agreement to repay it with interest over time. Loans are a common financial concept used in various areas of mathematics, such as finance, economics, and business.
What does compounded quarterly means?"Compounded quarterly" refers to a method of calculating interest or investment growth where the interest is added to the principal and then reinvested or recalculated at the end of each quarter (every three months) within a given time period.
To calculate Carmine's loan balance after two years, we need to use the compound interest formula, which is given by:
A = P ×[tex](1+r/n)^{nt}[/tex]
Where:
A = the loan balance after t years
P = the initial principal amount (loan amount) = $11,500
r = annual interest rate = 8% or 0.08 (expressed as a decimal)
n = number of times interest is compounded per year = 4 (since it is compounded quarterly)
t = time in years = 2 (since Carmine made no payments for the first two years)
Putting the values into the formula, we get:
A = 11,500 × (1 + 0.08/4)⁸
A = 11,500 × (1 + 0.02)⁸
A = 11,500 × (1.02)⁸
A ≈ $13,827.72
So, Carmine's loan balance after two years would be approximately $13,827.72.

Edward opens a savings account with $250. The bank gives him an interest rate of 2.8% per year (simple interest). About how long will it take Edward to double his money? (SHOW WORK!!)
Equation: ___________________
Answer: __________________
Answer:
Equation: 250(1 + 0.028t) = 500
Answer: 36 years
Step-by-step explanation:
The equation we can use to solve this problem is the simple interest formula:
[tex]\boxed{A = P (1 + rt)}[/tex]
where:
A is the amount of money in the account after t years.P is the principal (initial amount).r is the interest rate per year (as a decimal).t is the time in years.Given the initial investment is $250 at an interest rate of 2.8%, and Edward wants to double his money:
A = $500P = $250r = 0.028Substite these values into the equation:
[tex]500=250(1+0.028t)[/tex]
Swap sides:
[tex]250(1+0.028t)=500[/tex]
Now solve for t:
[tex]\implies \dfrac{250(1+0.028t)}{250}=\dfrac{500}{250}[/tex]
[tex]\implies 1+0.028t=2[/tex]
[tex]\implies 1+0.028t-1=2-1[/tex]
[tex]\implies 0.028t=1[/tex]
[tex]\implies \dfrac{0.028t}{0.028}=\dfrac{1}{0.028}[/tex]
[tex]\implies t=35.71428571...[/tex]
Assuming the interest is applied annually on the anniversary of the account opening, it will take Edward 36 years to double his money with a 2.8% simple interest rate.

If the "y-value" is decreasing at rate of 2 units per second, the rate at which "x" is changing when x=3/2 is -1/3 units per second.
The point moves along a curve having equation as : y = 2x² + 1; and
We know that y is decreasing at a rate of 2 units per second. We have to find the rate at which "x" is changing when x = 3/2,
To solve this problem, we differentiate, the curve equation,
So, taking the derivative of both sides of the equation with respect to time "t",
We get,
⇒ d/dt (y) = d/dt (2x² + 1),
⇒ dy/dt = (4x) × dx/dt,
We are given that dy/dt = -2 (since y is decreasing at a rate of 2 units per second), and we need to find "dx/dt" when x = 3/2,
Substituting "x = 3/2" and "dy/dt = -2",
We get,
⇒ -2 = 4×(3/2)(dx/dt),
⇒ -2 = (6)×(dx/dt),
⇒ dx/dt = -1/3,

From the problem, we know that:
X + Y + Z = 7600 ---(1) (the total amount invested is $7600)
0.06X + 0.09Y + 0.13Z = 818 ---(2) (the total income from the investments is $818)
Z = X + Y + 1200 ---(3) (the amount invested at 13% is $1200 more than the amounts invested at 6% and 9% combined)
We can use equation (3) to substitute for Z in equations (1) and (2), then solve for X and Y as follows:
X + Y + (X + Y + 1200) = 7600
2X + 2Y = 6400
X + Y = 3200
0.06X + 0.09Y + 0.13(X + Y + 1200) = 818
0.06X + 0.09Y + 0.13X + 0.13Y + 156 = 818
0.19X + 0.22Y = 662
Using the system of equations X + Y = 3200 and 0.19X + 0.22Y = 662, we can solve for X and Y to get:
X = 800
Y = 2400
Substituting back into equation (3), we get:
Z = X + Y + 1200 = 4400
Therefore, the amounts invested at 6%, 9%, and 13% were $800, $2400, and $4400 respectively.
