The increasing exponential functions are described as follows:
f(t) = a(1 + r)^t.
In which the parameters are listed as follows:
a is the initial value.r is the growth rate.For the old factory, the function is of:
p (w) = 230(1.1)^w.
Hence:
During week 0, 230 items are produced.The growth rate is of 10%.For the new factory, from the graph given at the end of the answer, the parameters are given as follows:
a = 190, which is the intercept.b = 1.1578, as 220/190 = 1.1578.Hence the function is:
pn(w) = 190(1.1578)^w.
The new factory overtakes the old factory when:
pn(w) > p(w)
190(1.1578)^w > 230(1.1)^w
(1.1578/1.1)^w > 230/190
wlog(1.1578/1.1) > log(230/190)
w > log(230/190)/log(1.1578/1.1)
w > 3.73 weeks.

Answer:
s is the price of each laptop that gives maximum profit
p is the maximum total profit that can be made.
Step-by-step explanation:
See the attached worksheet for additional explanation. The question asks for the meaning of s (selling price) and p (total profits) at the vertex of the curve. s is in units of price/laptop, while p is in units of total profits. Implicit in this graph is a demand curve (not shown) that illustrates how demand for laptops changes as the price changes. Also not shown, but assumed, is that if the laptops are sold at a low price, the declining profit margins resuce the overall total profits. This graph incorporates the cost and demand imformation in a manner that provides a condensed view of the more important variable: total profits.

Total cost of cement that Marcus has to pay is $6.5.
What is volume?
Volume could be a measure of occupied three-dimensional area. it's usually quantified numerically using SI derived units or by numerous imperial or North American country customary units.
Main body:
According to question:
Length of concrete patio = 15 ft
Width of patio = 9 ft
Height of patio = 3 inches
So first we need to convert inches into ft.
we know that ,
12 inches = 1 ft.
3 inches = (1/12)*3
3 inches = 1/4 ft
Volume of concrete patio = l*b*h
volume = 15*9*1/4
= 33.75 cubic ft.
Now we need to convert feet into yard as cost is given in cubic yard
1 cubic foot = 0.03704 cubic yards
33.75 cubic foot = 0.03704 * 33.75
= 1.2501 cubic yards
So cost of cement = total volume * cost of cement sack
cost = 1.25 * 5.2
cost = $6.5

The upper limit is 0.79
The class interval's upper limit is its highest value. Similarly, the lower limit is the class interval's smallest value.
Given that n = 200 and standard deviation σ = 0.025
σ = (√n/√n) = 0.025
Now calculate p
P = defectives/total inspected
= 145/200
P = 0.72
Q= 1-p
= 1- 0.72
= 0.18
Now calculate the upper limit
UCL = p – (-3 x σ)
= 0.72 – ( -3 x 0.025)
= 0.72 – (-0.075)
= 0.72 + 0.075

Option B. From the parallelogram PQRS the value of y is given to be 30
How to solve for the value of y from the parallelogramIn order to get the value of y we have to use the formula
2y + 120 = 80
where the value 120 is the angle that is stated as 120 from the question
2y = 180 - 120
2y = 60
y = 60 / 2
y = 30
Hence the value of y = 30
We can go ahead to get the value of x as well
3x + 120 = 180
take the like terms
3x = 180 - 120

What is least common multiple?
The least common multiple (LCM) of two numbers is the lowest possible number that can be divisible by both numbers.
It can be calculated for two or more numbers as well.
For example, LCM of 10, 2 and 7 is 70.
According to the given question:
Now n must be divisible by every positive integer less than 7, or
1, 2, 3, 4, 5, and 6.
Each number that is divisible by each of these is a multiple of their least common multiple.
LCM (1,2,3,4,5,6) = 60
So each number divisible by these is a multiple of 60.
The smallest multiple of 60 is clearly 60, so the second smallest multiple of 60 is 2 x 60 = 120.

You have a gift certificate to a book store worth $95. Each paperback books is $10 and each hardcover books is

model the number of each kind of books you can buy. Let x = the number of paperback books and y = the number
of hardback books
Answer: You make a system of inequality to spend at least $20. The word "at least" means you can spend equal to $20 or higher than $20. Or you can write it as,
⇒ what you buy should be ≥ 20
Input the price to the inequality above
⇒ what you buy should be ≥ 20
⇒ paperback price + hardcover price ≥ 20
⇒ 10x + 17y ≥ 20
Because the number of paperback books and the number of hardcover books can't be negative, make new inequality forms
⇒ x ≥ 0
⇒ y ≥ 0
So this is the summary
10x + 17y ≥ 20
x ≥ 0

L(d)=209-8d
Question a.)
If 154 miles of the road is left to be paved, how many days has the crew been paving the road?
Question b.)
How many miles of the road does the crew have left to pave after 13 days?
Answer:
a) 6 7/8 days
b) 105 miles
Step-by-step explanation:
Given that L(d) = 209 -8d miles of road remain to be paved after d days, you want to know (a) the number of days paving if 154 miles remain, and (b) remaining miles after 13 days.
a) Paving daysWe want to find d such that L(d) = 154.
L(d) = 154
209 -8d = 154 . . . . . . substitute for L(d)
209 -154 = 8d . . . . . add 8d-154
55/8 = d = 6 7/8 . . . divide by 8
The crew has been paving for 6 7/8 days if 154 miles remain.
b) Remaining milesAfter 13 days, the remaining miles will be ...
L(13) = 209 -8·13 = 209 -104
L(13) = 105
After 13 days, the crew has 105 miles left to pave.

Let y= total hours biked
How many hours did suzette run?
How many hours did she bike?
In total 4 hours Suzette ran for 1 hour and biked for 3 hours having average speed 5mph and 15mph respectively.
What is Average Speed?
Average speed is defined as total distance covered by the body divided by the time taken.
Average speed = Total distance covered/ total time taken
According to the given question:
Let x = total hours ran and y = total hours biked
Total time she ran and biked = 4h
∴ x + y = 4 ----- 1)
Total distance she biked and ran = 50 miles
Now, average running speed = 5 mph
Distance she ran = 5x
Similarly average biking speed = 15 mph
Distance she biked = 15y
∴ 5x + 15y = 50 ----- 2)
Solving 1) and 2) to get the values of x and y
Substituting x = 4 - y from 1) in 2)
5 (4 - y) + 15y = 50
On solving further we get y = 3
Substituting y = 3 to get x
x = 4 - 3
x = 1
