f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily
Step-by-step explanation:
We can rewrite the equation using the model:
P = Po * (1 + r/n) ^ (nt)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the relation of the rate and the time (in our case, the rate is weekly and the time will be in days, so n = 7)
With P = f(x), Po = 86, r = 0.18 and t = x, we have:
f(x) = 86 * (1 + 0.18/7) ^ (7x)
f(x) = 86 * (1.02) ^ (7x)
So the daily rate of growth is approximately 2%
Correct option: third one
Write an inequality that compares 3 and 5
Answer:
3 < 5
Step-by-step explanation:
3 < 5
We can write this inequality, because three is less than five, and < means less than.
An inequality is a mathematical sentence which
states that two expressions are not equal.
The "<" symbol means less than.
Since 3 is less than 5, we can write this as 3 < 5.

The angles of a quadrilateral are in the ratio 2: 3: 5: 8. Find the measure of each angles.
Answer:
see below
Step-by-step explanation:
Let's call the angles 2x, 3x, 5x and 8x and since the sum of angles in a quadrilateral is 360 degrees we can write:
2x + 3x + 5x + 8x = 360
18x = 360
x = 20 which means the angle measures are 40°, 60°, 100° and 160°
Answer:
40°,60°,100° and 160°
Step-by-step explanation:
First add all the ratio's together
2 + 3 + 5 + 8 = 5 + 13 = 18
Now we utilise the fact that angles in quadrilaterals add up to 360. We form an equation like this 18x = 360 to find the value of x and then substitute back into the ratio's
18x = 360
→ Divide both sides by 18 to isolate x
x = 20
Multiply 20 by each of the ratio's to find the angles of this quadrilateral
2 × 20 = 40
3 × 20 = 60
5 × 20 = 100
8 × 20 = 160
So the angles of a quadrilateral with the ratio of 2: 3 : 5 : 8 is 40,60,100 and 160

Step-by-step explanation:
First we solve for the whole rectangle:
Formula: A = ab
side length a = 5 in
side length b = 4 in
diagonal p = q = 6.4031242374328 in
perimeter P = 18 in
area A = 20 in²
Second we deduct the Area of the cutout of the Square

Solve each equation (steps as to how appreciated)
Answer:
{10, -8} (A)
Step-by-step explanation:
Since it is absolute value, n-1 can equal both 9 or -9.
First you solve for n-1=9. That would make n=10
Then you solve for n-1= -9 .That would make n=-8
Answer:
A) {10, -8}
Step-by-step explanation:
Since it is absolute value, you must split it into two equations:
n-1=9
n-1=-9
Now solve for n in both equations
n=10
n=-8
Therefore, the answer is A

The total length of a beach is 13.2 kilometers. If lifeguards are stationed every 0.06 kilometers, including one at the end of the beach, how many lifeguards will there be on the beach?
Answer:
220 lifeguards
Step-by-step explanation:
We have to divide the length of the beach by the interval of the stationed lifeguards.
13.2 / 0.06 = 220 lifeguards
There are 220 lifeguards.
An architect is making a plan for a new circular playground. If the picture below is the playground, how much fencing needs to go up to keep the kids in the circle? ⬇⬇⬇
Answer:
Length of the fencing required = 201.06 meters
Step-by-step explanation:
Architect is planning a circular playground with diameter = 64 m
We have to calculate the fencing required to cover this playground.
Length of fencing = circumference of the playground
Since circumference of a circle = π × (Diameter)
= 64π
= 201.06 meters
Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
What is the difference between the highest and lowest points in a data set?
the mean
the median
the mode
the range
Answer:
range
Step-by-step explanation:
difference between the highest and lowest points in a data set = range
The mean is the average of all the points
The median is the middle of all the points
The mode is the point the appears the most often
"Hey diddle diddle the medians the middle you add and divide for the mean the mode is the one that you see the most and the range is the difference between"
Online song that's helped me remember the difference between median, mode, mean and range for years!

Answer:

Step-by-step explanation:
Let Brandon's age be b. We can write 4b = b + 27 which gives us b = 9. Because Michael is 4 times as old as Brandon, he is 9 * 4 = 36 years old.
Answer:
36
Step-by-step explanation:
Micheal is 4 times as old as Brandon.
y = 4x
Micheal is also 27 years older than Brandon.
y = x +27
Y represents Micheal's age, and x represents Brandon's age.
Since both equations above are equal to the same value, y, you can set the two equations equal to each other. Solve for x.
4x = x + 27
3x = 27
x = 9
Brandon is 9 years old.
Plug Brandon's age into one of the equation to solve for Micheal's age.
y = x + 27
y = 9 + 27
y = 36
Micheal is 36 years old.
Joan draws a bar chart to show the temperatures at midday on March 1st in five cities. Joan has made four mistakes in her diagram. Write down any three of them.
Answer:
Step-by-step explanation:
Properties of a bar graph:
1). There should be equal space between the bars or the columns.
2). Width of each bar or columns should be same.
3). All bars should have same base.
4). Height of each bar will show the value of the data.
By these properties,
- Space between London-Paris, Rome-Oslo are not equal.
- Width of Munich bar is different from other bars.
A display case has room for 10 statues. Find the number of ways you can line up the statues if you have 5 statues
(Just and Example so it'll kinda explain it.)
Example A
How many ways can 5 students sit in a row?
Solution: If we consider the students sitting in one of five seats, then we have 5 students to choose from for the first seat, four remaining to choose from for the second seat and so on until all the seats are filled.
5–×4–×3–×2–×1–=120 So there are 120 ways to seat the students.
More Guidance
The way we just wrote out 5–×4–×3–×2–×1– can also be expressed as a factorial. A factorial is the product of a number with each number less than itself. We use the notation, 5!, which is read as “five factorial” to represent the expression 5–×4–×3–×2–×1–. It is important to note that 0!=1!=1. Students are often perplexed that both zero and one factorial are equal to one but think back to the context for illustration. If you want to arrange zero items, how many ways can you do it? If you want to arrange one item, how many ways can you do it? There is only one way to “arrange” zero or one item.

4a + 6b = 24
6a - 12b = -6
Given the equations what is the value of a+b?
PLZ HELP WILL MARK BRAINLIEST
Answer:
5
Step-by-step explanation:
4a + 6b = 24
6a - 12b = -6
Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.
4a + 6b = 24
+ 3a - 6b = -3
----------------------------
7a = 21
Divide both sides by 7.
a = 3
Now substitute 3 for a in the first equation and solve for b.
4a + 6b = 24
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
a = 3, and b = 2
a + b = 3 + 2 = 5
