Step-by-step explanation:
The question given is:
Subtracting [tex]3x^2+4x-5[/tex] from [tex]7x^2+x+9[/tex] results in a polynomial. After subtracting [tex]4x^2-3x[/tex] from this polynomial the difference is?
First we will Subtracting [tex]3x^2+4x-5[/tex] from [tex]7x^2+x+9[/tex]
[tex]7x^2+x+9-(3x^2+4x-5)\\=7x^2+x+9-3x^2-4x+5\\Combining\:like\:terms\\=7x^2-3x^2+x-4x+9+5\\=4x^2-3x+14[/tex]
So, the polynomial we get is: [tex]4x^2-3x+14[/tex]
Now, subtracting [tex]4x^2-3x\: from\: 4x^2-3x+14[/tex]
[tex]4x^2-3x+14-(4x^2-3x) \\=4x^2-3x+14-4x^2+3x\\Combining\:like\:terms\\=4x^2-4x^2-3x+3x+14\\=14[/tex]
The difference is 14
So, Subtracting [tex]3x^2+4x-5[/tex] from [tex]7x^2+x+9[/tex] results in a polynomial. After subtracting [tex]4x^2-3x[/tex] from this polynomial the difference is 14

Ella invested $2,700 in an account paying an interest rate of 5.4% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $4,020?
Answers
Answer:
7.4 years
Step-by-step explanation:
This is a compound interest question, from the question, we know we are to find the time.
The formula for Time in compound interest =
t = ln(A/P) / n[ln(1 + r/n)]
Where:
A = Amount after time t = $4,020
P = Principle = Initial amount invested = $2700
r = Interest rate = 5.4% = 0.054
t = ??
n = compounding frequency = monthly = 12
t = ln(A/P) / n[ln(1 + r/n)]
t = In(4020/2700)/12[In(1 + 0.054/12)]
t = 7.388 years
Approximately = 7.4 years

What is the value of x?
Answers
Answer:
x = 3 sqrt 2
Step-by-step explanation:
We know that this is a 45, 45m 90 special right triangle. In this special right triangle the side lengths are x, x and the hypotenuse is x sqrt 2 (we can prove this using pythagoreans theorem). 6 is the hypotenuse, meaning that it is equal to x sqrt 2:
6 = x sqrt 2
x = 6/sqrt 2
Rationalize the denominator:
x = (6 sqrt 2)/2
x = 3 sqrt 2

Margaret invested $2000 into an account earning 4% interest compounded continuously. How much will her investment be worth after 5 years?
Answers
Answer:
$400
Step-by-step explanation:
The required, worth of the Margret investment after 5 years will be $2442.8.
What is compound interest?Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
here,
Margaret invested $2000 into an account earning 4% interest compounded continuously.
Principal = $2000
Rate = 4% or 0.04
tenure = 5 years,
[tex]Amount = Pe^{rt}[/tex]
Substitute the values in the above equation,
[tex]Amount = 2000 \times e^{0.04 \times 5}\\Amount = 2442.8[/tex]
Thus, investment of Margret after 5 years becomes $2442.8.

A quantity with an initial value of 160 grows continuously at a rate of 0.65% per hour.
What is the value of the quantity after 402 minutes, to the nearest hundredth?
Answers
Answer:
167.10
Step-by-step explanation:
Here, we write out the general form for an exponential equation;
y = I (1 + r)^n
where y is the current value which we want to calculate
I is the initial value which is 160
r is the growth rate = 0.65% = 0.65/100 = 0.0065
402 minutes to hours will be 402/60 = 6.7 hours which is n
Substituting these values, we have
y = 160( 1 + 0.0065)^6.7
y = 160(1.0065)^6.7
y = 167.10

At a local amusement park 70% of the rides are 48 inches taller if there are 80 rides in total how many are made for kids who are 48 inches and taller?
Answers
Answer:
56 rides
Step-by-step explanation:
Total number of rides = 80 rides
If 70% of the rides are 48 inches taller, the total number of rides 70% taller wil be;
Rides 48 inches taller = 70% * 80
Rides 48 inches taller = 0.7 * 80
Rides 48 inches taller = 56
Hence the total rids made for kids that are 48inches taller is 56 rides

Suppose f(x) = x2. What is the graph of g(x) = f(3x)?
Answers
Answer:
we conclude that g(x) = 9x² is the result of f(x) vertically stretched by multiplying each of its y-coordinates by 9.
Also, check the attached graph is matched with option B.
Hence, option (B) is the correct graph.
Step-by-step explanation:
Given
f(x) = x²g(x) = f(3x)so
g(x) = (3x)² = 9x²Thus, the graph of g(x) = 9x² is shown below.
From the graph, it is clear that at x = 0, y = 0
So, the y-intercept is at (0, 0).
Clearly
f(x) = x²g(x) = 9x²Note that the vertex of the graph also lies at (0, 0), because it is clear that g(x) = 9x² is the result of f(x) vertically stretched by multiplying each of its y-coordinates by 9.
Since 9 > 0, it means g(x) = 9x² is vertically stretched by multiplying each of its y-coordinates by 9.
Therefore, we conclude that g(x) = 9x² is the result of f(x) vertically stretched by multiplying each of its y-coordinates by 9.
Also, check the attached graph is matched with option B.
Hence, option (B) is the correct graph.
In preparation for the holiday season, Big Bird Co. decided to increase production of stuffed Bert characters by 30%.
If the company had been producing 350 Bert characters per day, how many additional characters will the factory be creating per day?
Answers
Answer:
the additional characters will the factory creating per day is 105 characters
Step-by-step explanation:
The computation of the additional characters will the factory creating per day is shown below
= Number of character produced × (1 + increased percentage)
= 350 × (1 + 0.30)
= 350 × 1.30
= 455 characters
Now the additional characters would be
= 455 - 350
= 105 characters
hence, the additional characters will the factory creating per day is 105 characters

The maximum height of an ad that the company can afford is 20 inches.
Step-by-step explanation:
2,050 = 50 + 10(h * w),
where h is height, w is width and h = 2w.
2,050 = 50 + 10(h * w)
(subtract 50 from each side)
2,000 = 10(h * w)
(divide each side by 10)
200 = h * w
(substitute 2w for h)
200 = 2w * w
(divide each side by 2 and simplify)
100 = w * w
100 = w²
(find the square root of each side)
10 = w
So if the width is 10, then since the height is twice the width, then the height has to be 20.
