Answer:
2
Step-by-step explanation:
We assume your recursive formula is ...
[tex]a_1=2\\a_n=a_{n-1}^2-2[/tex]
Using this to find a4, we get ...
[tex]a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}[/tex]
-7x=x² + 12
A)
x = 3, x = 5
B)
x = 3.x = 4.17
X = -3, x = 5
D)
x = -4X=-3
Answer:
D. x = −3, −4
Step-by-step explanation:
1) Move all terms to one side.
7x+ + 12=0
2) Factor 7x + [tex]x^{2}[/tex] + 12.
(x + 3)(x + 4) = 0
3) Solve for x.
x = −3, −4

Find two consecutive ODD integers such that: The square of the larger is 120 more than the square of the smaller
Answer: See explanation
Step-by-step explanation:
Le the number be x and x+2
The information given can be formed into and equation as:
(x + 2)² = x² + 120
(x + 2)(x + 2) = x² + 120
x² + 2x + 2x + 4 = x² + 120
Collect like terms
x² - x² + 2x + 2x = 120 - 4
4x = 116
x = 116/4
x = 29
The smallest number is 29
The larger number is x + 2 = 29 + 2 = 31

identify the slope and the intercept for the following inequality -2×-y
[tex]\Huge{\textbf{\textsf{{\color{navy}{ᴀɴ}}{\purple{ᴡs}}{\pink{ᴇʀ}}{\color{pink}{:}}}}}[/tex]
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
(a) Jasmine ran 55 miles in 4242 minutes. Part A At what rate did Jasmine run? Jasmine ran at a rate of minutes per mile. Part B Katie ran 44 miles. She ran at a rate that was 1.11.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer.
Answer:
Part A
0.764 minutes/miles
Part B
48.4 minutes
Step-by-step explanation:
a) Jasmine ran 55 miles in 42 minutes. Part A At what rate did Jasmine run?
Jasmine ran at a rate of minutes per mile.
Rate = Minutes/Miles
Minutes = 42 minutes
Miles = 55 miles
Jasmine's rate = 42 minutes/55 miles
= 0.7636363636 minutes/miles
Approximately = 0.764 minutes/miles
Part B
Katie ran 44 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine. For how many minutes did Katie run? Explain how you determined your answer.
Rate = Minutes/Miles
Minutes = ?
Miles = 44 miles
Rate = 1.1 minutes per miles
Hence:
1.1 minutes per miles = x/44 miles
x = 1.1 minutes per miles × 44 miles
x = 48.4 minutes
MODELING WITH MATHEMATICS A contractor extends a house on two sides.
A. The area of the house after the the renovation is represented by (x+50)^2
B. Use the polynomial in part (a) to find the area when x=15. What is the area of the extension?
Answer:House=4,225ft^2
Step-by-step explanation:
(15)^2+100(15)+2,500
=225+1,500+2,500
=4,225
(a) The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]
(b) Area of the extension
House =4225 ft^2
Important information :
The area of the house is represented by quadratic expression
[tex](x+50)^2[/tex]
To find out the product to multiply x+50 twice
[tex](x+50)(x+50)[/tex]
Apply FOIL method to multiply the parenthesis
[tex](x+50)(x+50)\\x^2+100x+2500[/tex]
The area of the house is [tex]x^2+100x+2500 \; \; ft^2[/tex]
(b) given x=15. To find area of extension , we replace x with 15 in the answer we got from part (a)
[tex]x^2+100x+2500 \\x=15\\(15)^2+100(15)+2500 \\225+1500+2500\\4,225[/tex]
Area of the extension
House =4225 ft^2

The cost to rent a ballroom is $293 up front plus an additional $59 per hour. If a ballroom is rented for 6 hours, what is the cost?
Answer:$647
Step-by-step explanation:
293+(59*6)=
293+454=
647
First start off with 293
Now multiply 59 by 6 because 6 is how many hours they will rent it for.
59 x 6 = 354
After that add the 354 to the 293 we had before.
293 + 354 = 647
So the cost of the ball room would be 647 dollars.

find compound interest paid when a sum of Rupees 10,000 is invested for 1year & 3 months at 17/2% per annum compounded annualy.
Answer:
Rs 1,073.56
Step-by-step explanation:
The computation of the compound interest is shown below:
Compound interest = Principal (1 + rate of interest)^time period - Principal
= Rs 10,000 × (1 + 17 ÷ 2%)^1.25 - Rs 10,000
= Rs 10,000 × (1 + 0.085)^1.25 - Rs 10,000
= Rs 11073.56 - Rs 10,000
= Rs 1,073.56
The 1.25 come from
1 year & 3 months
= 5 by 4
