Charmaine deposited $2000 into an account with a 3.9% annual interest rate, compounded quarterly. Assuming that no withdrawals are made, how long will it take for the investment to grow to $4000?
Answer:
17 years & 9 months
Step-by-step explanation:
annual rate 3.9%
every quarter = 3.9%/4 = 0.98%
compounding every quarter = (1+0.98%)
how long = assuming t quarters
2000 * (1+0.98%) ^t = 4000
solve for t
t= 71
so 71/4 = 17 years & 9 months

What are perpendicular lines?In Mathematics and Geometry, perpendicular lines can be defined as two (2) lines that intersect or meet each other at an angle of 90° (right angles).
By critically observing the geometric shape, we can reasonably infer and logically deduce that line segment BD is perpendicular to line segment BE.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

A landscape architect is seeding a 4800-sq ft lawn. If the seed manufacturer recommends using 3 lb of seed per 1200 sq ft, how many pounds of seed will be needed?
The architect will need ____ ib of seed
Answer:
12 lb of seed.
Step-by-step explanation:
We need to determine the amount of seed required for a 4800 sq ft lawn.
First, we need to find out how many 1200 sq ft portions the 4800 sq ft lawn is:
4800 sq ft / 1200 sq ft/portion = 4 portions
Next, we can use the seed manufacturer's recommendation of 3 lb of seed per 1200 sq ft:
3 lb/portion * 4 portions = 12 lb
Therefore, the architect will need 12 lb of seed.
The three sides of base of triangular prism are 6cm,5cm,x cm respectively.If the length of prism is 20 and its lateral surface area is 360 square cm find the value of x
Answer: 7
Step-by-step explanation:
We know that the base sides of the triangular prism are 6cm, 5cm, and
[tex]x[/tex] cm. We also know that the length of the prism is 20.
To calculate the lateral surface area of the triangular prism, we need to use the following equation:
[tex](a + b + c)[/tex] x [tex]length[/tex]
So we can input our values, to get this:
[tex](6 + 5 + x) 20 = 360[/tex]
Then we solve the equation by the following steps:
[tex]= > 6+5+x = \frac{360}{20} = 18\\= > 11 + x = 18\\= > x = 7[/tex]

The equation is
B) Solve your equation in part [A] to find the original price of the love seat.
Answer: The original price of the love seat was
dollars.
The equation which can be used to represent the situation is 396 = x - 0.2x
The original price of the love seat was $495.
What was the price of the love seat before the reduction?Let
Original price of the love seat= x
New price= $396
Percentage discount= 20%
396 = x - (20% of x)
396 = x - 0.2x
396 = 0.8x
divide both sides by 0.8
x = 396 / 0.8
x = $495
Hence, the equation 396 = x - 0.2x is used to solve the question and the original price is $596

evaluate the numerical value of the final momentum of the t-shirt using the results from parts a and b.
The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is the sum of the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied.
The final amount momentum of the t-shirt is 17.5 kg⋅m/s, which is calculated by summing the initial momentum of the t-shirt (2 kg⋅m/s) and the change in momentum (15.5 kg⋅m/s) due to the force applied. Momentum is a vector quantity which is equal to the product of the mass and velocity of an object. In this case, the t-shirt has a mass of 4 kg and a velocity of 4 m/s. The force of 15 N applied to the t-shirt for 3 seconds causes the t-shirt to accelerate, increasing its velocity from 4 m/s to 8 m/s. This increase in velocity results in an increase in the momentum of the t-shirt from 2 kg⋅m/s to 17.5 kg⋅m/s. Thus, by calculating the change in momentum due to the applied force, we can determine the final momentum of the t-shirt.

Mary decides to get phone service from T-Mobile. T-Mobile offers her a plan where she will have to pay $40 per month with a $35 activation fee. What’s her equation using y=mx+b
Answer:
y=40x+35
Step-by-step explanation:
After 0 months, she still needs to pay the first $35. This means that this is her y-intercept, and in the formula “y=mx+b”, it would go in the “b” place. Then x would mean how many months have passed, so therefore 40 would go into the “m” place. If you put that together, it looks like “y=40x+35”.

Show your work.
Answer:
(x + 7)/(x - 3)
Step-by-step explanation:
To simplify this expression, we first factor the numerator and denominator, and then cancel any common factors:
x² + 3x - 28 = (x + 7)(x - 4)
x² - 7x + 12 = (x - 3)(x - 4)
So the expression simplifies to:
(x + 7)(x - 4) / (x - 3)(x - 4)The (x - 4)
factor in both the numerator and denominator cancels out, leaving:
x + 7 / x - 3
Therefore, the simplified expression is (x + 7)/(x - 3)

Name the two solutions of 25 = (x – 3)^2
Answer: x = 8, x = -2
Step-by-step explanation:
(x - 3)² = 25
Step 1: Take the square root on each side of the equation.
(x - 3)² = 25
√(x - 3)² = ±√25
Step 2: After taking the square root on each side of the equation, this allows you to solve for x.
x - 3 = ±5
Solution 1
x - 3 = 5
x = 5 + 3
x = 8
Solution 2
x - 3 = - 5
x = -5 + 3
x = -2
Another way to solve this problem is to multiply (x - 3)² using the FOIL methods (first, outer, inner, last) and then set it equal to 25.
(x - 3) (x - 3) = 25
x² - 3x - 3x + 9 = 25
The next step is to add like terms. After adding like terms, solve for x.
x² - 3x - 3x + 9 = 25
x² - 6x + 9 - 25 = 25 - 25
x² - 6x - 16 = 0
Last step is to factor x² - 6x - 16 = 0 so you can solve for the two solutions.
(x - 8) (x + 2) = 0
Solution 1
x - 8 = 0
x = 8
Solution 2
x + 2 = 0
x = -2

What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
12 > 2x + 4
Now, if we put x= 8 then
= 2x+ 8
= 2(8)+8
= 16+ 8
= 24 > 12
So, x=8 is not true
Now, if we put x= 4 then
= 2x+ 8
= 2(4)+8
= 8+ 8
= 16 > 12
So, x=4 is not true
Now, if we put x= 12 then
= 2x+ 8
= 2(12 )+8
= 24 + 8
= 32 > 12
So, x=12 is not true
and, if we put x= -2 then
= 2x+ 8
= 2(-2)+8
= -4+ 8
= 4 < 12
So, x=-2 is true.

Find the transformation Matrix R that describes a rotation by 120° about axis from the origin through the point (1,1,1)
Answer: The transformation matrix R for a rotation of 120° about an axis from the origin through the point (1,1,1) can be calculated using the formula:
R = I + (sin(θ))U + (1-cos(θ))UU'
where θ is the angle of rotation (120° in this case), I is the identity matrix, U is a skew-symmetric matrix, and U' is its transpose. The skew-symmetric matrix can be calculated as follows:
U = [0, -z, y; z, 0, -x; -y, x, 0]
where x, y, and z are the components of the vector (1,1,1) that defines the axis of rotation.
Plugging in the values and simplifying, the transformation matrix R is:
R = [ cos(120°), -sin(120°), 0; sin(120°), cos(120°), 0; 0, 0, 1 ]
Note: cos(120°) = -1/2 and sin(120°) = √(3)/2.
