Answer:
2.3 hours rounded I suppose.
Step-by-step explanation:
You have jogged 5 miles from the park at a rate of r miles per hour. On your way back to the park your average speed increases by 1 mile per hour.
a. Write an expression for the time t (in hours) it takes to jog 5 miles
from the park as a function of your average speed r (in miles per hour) ___________
b. When you run back to the park, your average speed increases by 1 mph.
Write an expression representing your new speed. ___________
c. Write an expression for the time t(in hours) it takes to jog 5 miles
back to the park. ___________
d. Use your answers to parts a and c to write an expression that gives the total jogging time T (in hours) as a function of your average speed r (in miles per hour) when you are jogging away from the park. Write your answer as a single rational expression.
e. Find the total jogging time if you jogged away from the park at an average speed (r) of 4 miles per hour. Round your answer to the nearest tenth.

Step-by-step explanation:
=========================================================
Work Shown:
The smaller angles UVN and NVW add up to the largest angle UVW.
This is due to the angle addition postulate.
(angle UVN) + (angle NVW) = angle UVW
(6x+13) + (46) = 11+10x
6x + 59 = 11 + 10x
6x - 10x = 11 - 59
-4x = -48
x = -48/(-4)
x = 12
----------------
Extra info:
If you're curious about the angles, then we use that x value to find them
angle UVN = 6x+13 = 6*12+13 = 72+13 = 85 degreesangle NVW = 46 degreesangle UVW = 11+10x = 11+10*12 = 11 + 120 = 131 degreesNote how 85+46 = 131 to show that (angle UVN) + (angle NVW) = angle UVW is a true equation. This confirms our answer for x.
Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?
Answer:
so just successive powers of 2
Step-by-step explanation:
1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.
The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.
Given that,
To justify the given sequences 1,3,7,15.
Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
Given a sequence, 1,3,7,15
where first term A0 = 1
second term A1 = 1 + 2 = 3
third term A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)
Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

HIGHER ORDER THINKING A cell phone plan is shown on the right. The rates, which include an unlimited data plan, are the same each month for 7 months. The total cost for all 7 months is $180.39. Let m represent the average number of minutes that exceeds 700 minutes each month. A. Write an equation to represent the given situation. B. Solve the equation to determine how many additional minutes, on average, you use each month.
Answer: (a). M=7x180+39+700. (B) $731
Step-by-step explanation:
Equation to represent the given situation is 7(19.70 + 1.97 + m X 0.05) = 180.39; additional minutes, on average, you use each month is 82
What is Linear Equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given that;
Total cost for 7 month =$180.39
Let m be the average number of minutes that exceeds 700 minutes every month
Equation formed;
7(19.70 + 1.97 + m X 0.05) = 180.39,
or, 7(19.70 + 1.97 + m X 0.05) = 180.39,
or, 21.67 + 0.05m = 180.39/ 7,
or, 0.05m = 25.77 – 21.67,
0.05m = 4.1
m= 82
Therefore, equation for (a) : 7(19.70 + 1.97 + m X 0.05) = 180.39 and 82 will be the answer of (b)

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17

Over which interval on the x-axis is there a negative
rate of change in the function?
O-2 to -1
O -1.5 to 0.5
O 0 to 1
O 0.5 to 1.5
There is a negative rate of change in the function In the interval (-2,-1) on the x-axis.
What is the average rate of change between two coordinates?The slope of the straight line connecting two points is the average rate of change between those two coordinates.
We can infer from the graph,
the slope of the straight line connecting these points is negative in the range of -2 to -1.
As a result, the function's rate of change over this interval is negative.
Hence, In the interval –2 to –1 there is a negative rate of change in the function.
