Step-by-step explanation:
To find radical form with fractions , put the whole number (i.e 9) inside the square root, the denomination in the top of the square root (i.e 2) and the numerator is the power of the number inside the square root (in this case it is one so you would not put it there.)
A new shopping mall is gaining in popularity. Every day since it opened, the number of shoppers is 20% more than the number of shoppers the day before. The total number of shoppers over the first 4 days is 671. How many shoppers were at the mall on the first day?
Answer:
The number of buyers on the first day was approximately 324.
Step-by-step explanation:
In this case we have a initial number of shoppers "C" that we want to know and this grows at a steady rate of 20% per day, like a compound interest, we also know the total number of shoppers after 4 days, so we have the final amount of shoppers. We can use the formula for compound interest in order to calculate the number of shoppers in the first day as shown bellow:
M = C*(1 +i)^(t)
Where M is the total amount of shoppers, i is the growth rate and t is the time elapsed.
671 = C*(1 + 0.2)^(4)
671 = C*(1.2)^4
671 = C*2.0736
C = 671/2.0736 = 323.5918
Since there can't be a 0.59 buyer, we will round the number to 324.
Answer:
125 shoppers

witch table has the constant of proportionality between y and x of 8/5
table 1 table 2 table 3
4 32/5 2 14/5 5 20/3
10 16 6 42/5 9 12
11 88/5 20 28 12 16
Answer:
Table 1
Step-by-step explanation:
Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.
Table 1:
4 32/5
10 16
11 88/5
Let's find the constant of proportionality for each row:
R1: (32/5) / 4 = 8/5
R2: 16/10 = 8/5
R3: (88/5) / 11 = 8/5
Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.
If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.
Hope this helps!
Answer:
Table 1
Step-by-step explanation:
y = (8/5)x
32/5 = 8/5 × 4
32/5 = 32/5
16 = 32/5 × 10
16 = 16
88/5 = 8/5 × 11
88/5 = 88/5

Angel has finished 75% of an art project that has taken
him a total of 9 hours so far. If he continues to work at
the same rate, how many hours will it take for him to
complete the entire project?
Answer: 12 hours
Step-by-step explanation: For this problem we will write a percent equation to solve for 100% and how many total hours it will take angel to finish the entire project.
Lets write a equation to solve for w, total amount of hours.
9/w = 75/100
9/w x w = 75/100 x w
9 = 75w/100
9 x 100/75 = 75w/100 x 100/75
w = 12
So, it will take Angel 12 hours to finish his entire project.
Final answer:
Angel will need 3 more hours to complete the art project, for a total of 12 hours when he continues to work at the same rate.
Explanation:
Angel has completed 75% of his art project in 9 hours. To find out how much time it will take to complete the entire project, we need to determine the time taken to complete 100% of the project. First, we calculate the time taken for 1% of the work, which is 9 hours divided by 75 (the percentage completed so far). This gives us 0.12 hours per percent.
Now, we can find out the total time for 100% completion by multiplying 0.12 hours by 100, which totals 12 hours. Since Angel has already completed 9 hours of work, the remaining time to finish the project is 12 hours minus 9 hours, which equals 3 more hours of work.

Answer:
y = 3x+2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (23-20)/(7-6)
=3/1
We know the slope is 3
Using the slope intercept form of a line
y= mx+b where is the slope and b is the y intercept
y = 3x+b
Using a point (1,5)
5 = 3(1)+b
Subtract 3 from each side
5-3= 3-3+b
2 = b
y = 3x+2
Answer:
B) y = 3x + 2
Step-by-step explanation:
Slope: (8 - 5)/(2 - 1)
= 3/1 = 3
y = 3x + c
5 = 3(1) + c
c = 5 - 3
c = 2
y = 3x + 2

Answer:
≈ 1347 mi²
Step-by-step explanation:
The shaded area is the difference between the outer area and the inner area
shaded area = outer - inner
= πr₁² - πr₂²
where r₁ = 14 + 11 = 25 and r₂ = 14, thus
A = π × 25² - π × 14² = 625π - 196π = 429π = 429 × 3.14 ≈ 1347 mi²
Answer:
Step-by-step explanation:
Area of the shaded region = Area of the Outer circle - Area of the inner circle
Outer circle:
r = 14+11 = 25 mi
Area = πr² = π*25²
Inner Circle:
r = 14 mi
Area = πr² = π*14²
Area of shaded region = π*25² - π*14²= π(25² - 14²)
= 3.14*(625 - 196)
=3.14*429
= 1347.06 mi²

What is the value of cos(150°)?
Final answer:
The value of cos(150°) is -0.866.
Explanation:
The value of cos(150°) can be determined using the unit circle or trigonometric ratios. Since 150° is in the second quadrant, the cosine value is negative. In the second quadrant, the reference angle is 180° - 150° = 30°. The reference angle corresponds to the angle on the unit circle with the same cosine value.
In the first quadrant, the cosine value is positive. The cosine of 30° is 0.866 (approximately). Since the angle is in the second quadrant, the cosine value will be the same but negative. Therefore, the value of cos(150°) is -0.866.

of the function over the interval 1 < x < 8.
Answer:
Submit Answer
Privacy Policy
Terms of Service
Answer:
- 2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [a, b ] = [1, 8 ], thus
f(b) = f(8) = - 8² + 7(8) + 14 = - 64 + 56 + 14 = 6
f(a) = f(1) = - 1² + 7(1) + 14 = - 1 + 7 + 14 = 20
average rate of change = [tex]\frac{6-20}{8-1}[/tex] = [tex]\frac{-14}{7}[/tex] = - 2
The number of users on a website has grown exponentially since its launch. After 2 months, there were 90 users. After 4 months, there were 810 users. Find the exponential function that models the number of users x months after the website was launched. Write your answer in the form f(x)=a(b)x.
Answer:
10(3)^x
Step-by-step explanation:
The function contains the points (2,90) and (4,810). Use the general form y=abx to write two equations:
90=ab^2 and 810=ab^4
Solve each equation for a:
a=90/b^2 and a=810/b^4
Since a=a, set the other sides of the equations equal and solve for b.
90/b2=810/b4
Cross multiply, then divide and simplify as follows:
90b^4=810b^2
b^4/b^2=810/90
b^2=90
b^3
Now, use the value of b and the point (2,90) to find the value of a.
90=a(3^2)
a=10
So, substitute answers in original equation for a final answer of f(x)=10(3)^x.
