Find the area of the shape.
Answer:
The area is [tex]78.54units^2[/tex]
The area would be 78.5[tex]units^2[/tex] (pi=3.14)
Step-by-step explanation:
The formula for the area of a circle is : [tex]\pi *radius^2[/tex]
To work the area of this quadrant you would first need to work out the area of the circle. You can do this by multiplying pi by the radius of 10 squared, this gives you 314.16.
The next step is to work out how much of the circle we need to work out the area for. As this is a right angle (90°) we know that this is [tex]\frac{1}{4}[/tex] of a circle. This is because the total of a circle is 360, and that by dividing 360 by 90, this gives you 4. This tells that this is a quarter of a circle.
The final step would be to divide the area of 314.16 by 4, this gives you 78.54. This is because we are using the area to work out the area of just one quadrant.
1) Multiply pi by 10 squared.
[tex]\pi*10^2=314.16^2[/tex]
2) Divide 360 by 90.
[tex]360/90=4[/tex]
3) Divide 314.16 by 4.
[tex]314.16/4=78.54^2[/tex]
Pi=3.14:
To work the area of this quadrant you would first need to work out the area of the circle. You can do this by multiplying pi by the radius of 10 squared, this gives you 314.

Find the coordinates of point B along a directed line segment from A(3,4) and
C(3,9) so that the ratio of AB to BC is 4:1.
We have been given two points. [tex]A(3,4)[/tex] and [tex]C(3,9)[/tex]. We are asked to find the point B such that it divides line segment AC so that the ratio of AB to BC is 4:1.
We will use segment formula to solve our given problem.
When a point P divides segment any segment internally in the ratio [tex]m:n[/tex], then coordinates of point P are:
[tex][\right x=\frac{mx_2+nx_1}{m+n},y=\frac{my_2+ny_1}{m+n}\left][/tex]
[tex](x_1,y_1)=(3,4)[/tex] and [tex](x_2,y_2)=(3,9)[/tex].
[tex]m=4,n=1[/tex]
Upon substituting our given information in above formula, we will get:
[tex][\right x=\frac{4(3)+1(3)}{4+1},y=\frac{4(9)+1(4)}{4+1}\left][/tex]
[tex][\right x=\frac{12+3}{5},y=\frac{36+4}{5}\left][/tex]
[tex][\right x=\frac{15}{5},y=\frac{40}{5}\left][/tex]
[tex][\right x=3,y=8\left][/tex]
Therefore, the coordinates of point B would be [tex](3,8)[/tex].

To find the number of mice with birth weights below 10 grams on a histogram, multiply the frequency by the given class width for that weight range and sum frequencies if multiple bars are relevant.
Explanation:The student is asking how to work out the number of mice with birth weights below 10 grams, based on a given histogram. Since the histogram is not displayed here, I will explain the general process for determining the number of mice under a certain weight category using a histogram. First, find the bar that represents the birth weights below 10 grams. The height of this bar corresponds to the frequency density for this class interval. If the class width (the range of values within the category) is 1 gram, then the frequency (number of mice) in this bar can be found by multiplying the frequency density by 1 gram. If the histogram does not provide frequency directly and instead gives frequency density, you must also know the class width to calculate the number of mice. Multiply the frequency density by the class width to find the frequency. If multiple bars (class intervals) cover birth weights below 10 grams, sum the frequencies of all relevant bars to calculate the total number of mice with weights below 10 grams.

David rode his bicycle for 6 hours and he jogged for 8 hours during the past 2 weeks. If he continues bicycling and jogging at the same rate, how many hours will he ride his bicycle and jog in 24 weeks?
Answer:
He will ride his bicycle for 72 hours and jog for 96 hours.
Step-by-step explanation:
David rode his bicycle for 6 hours and he jogged for 8 hours during the past 2 weeks.
We can say that per week, he rode his bicycle for 3hours and jogged for 4 hours.
Assuming that he continues at the same rate, in 24 weeks, he will ride his bike for:
24 * 3 = 72 hours
And he will jog for:
24 * 4 = 96 hours.
He will ride his bicycle for 72 hours and jog for 96 hours.
Answer:
72 all you need to do is 24 x 3 and you get 72. :)

Step-by-step explanation:
There were no given choices, but I did graph the equation using Desmos.
Choose the answer that is closest to this:
2x + 4 = 16
O A. x = 24
O B. x = 40
O c. x = 6
O D. x = 10
Answer:
C. x = 6
Step-by-step explanation:
You are solving for x. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First subtract 4 from both sides:
2x + 4 (-4) = 16 (-4)
2x = 16 - 4
2x = 12
Next, isolate the variable, x. Divide 2 from both sides:
(2x)/2 = (12)/2
x = 12/2
x = 6
C. x = 6 is your answer.

Step-by-step explanation:Write the series using summation notation.
4 + 8 + 12 + 16 + 20+ . . . + 80
Answer:
[tex]\sum ^{20} _{n \to \11} 4n[/tex]
Step-by-step explanation:
In order to write the series using the summation notation, first we need to find the nth term of the sequence formed. The sequence generated by the series is an arithmetic sequence as shown;
4, 8, 12, 16, 20...80
The nth term of an arithmetic sequence is expressed as Tn = a +(n-1)d
a is the first term = 4
d is the common difference = 21-8 = 8-4 = 4
n is the number of terms
On substituting, Tn = 4+(n-1)4
Tn = 4+4n-4
Tn = 4n
The nth term of the series is 4n.
Since the last term is 80, L = 4n
80 = 4n
n = 80/4
n = 20
This shows that the total number of terms in the sequence is 20
According to the series given 4 + 8 + 12 + 16 + 20+ . . . + 80 , we are to take the sum of the first 20terms of the sequence. Using summation notation;
4 + 8 + 12 + 16 + 20+ . . . + 80 = [tex]\sum ^{20} _{n \to \11} 4n[/tex]
The series 4 + 8 + 12 + 16 + 20 + ... + 80 can be expressed in summation notation as Σ[4 + (i - 1) × 4] for i = 1 to 20.
To write the series 4 + 8 + 12 + 16 + 20 + ... + 80 using summation notation, we first identify that it is an arithmetic series. An arithmetic series is a sequence of numbers in which the difference between consecutive terms is constant.
The given series: 4, 8, 12, 16, 20, ..., 80
We can observe that the common difference (d) is 4, and the first term (a) is 4. The nth term of an arithmetic series can be given by:
a + (n-1)d
Here, the nth term is 80. Setting up the equation for the nth term:
4 + (n-1)4 = 80
Simplifying this equation:
4 + 4n - 4 = 804n = 80n = 20
Thus, the series has 20 terms. We can write the series in summation notation as follows:
Σ[4 + (i - 1) × 4] for i = 1 to 20
To find the sum of this arithmetic series, we use the formula for the sum of an arithmetic series:
Sum = n/2 × (first term + last term)
Here, first term (a1) = 4, last term (an) = 80, and n = 20. So,
Sum = 20/2 × (4 + 80) = 10 × 84 = 840
Therefore, the summation notation for the series is Σ[4 + (i - 1) × 4] for i = 1 to 20, and its sum is 840.
At a music store, a survey was conducted to find which genre of music the customers preferred. In the survey, every male customer was asked which genre of music was his favorite. Were the results of the survey valid?
A.
Yes, because the music store surveyed every tenth male customer.
B.
No, because the music store did not survey a sample that is representative of the population.
C.
No, because the music store did not have any female customers.
D.
Yes, because every male customer was surveyed.
Answer:
The answer is B
Step-by-step explanation:
I have study Island too and the answer C is wrong
Final answer:
The survey conducted only among male customers at a music store is not valid because it's not representative of the entire customer base, thereby introducing a selection bias.
Explanation:
The question asks whether the results of a music preference survey conducted only among male customers at a music store are valid. Answer choice B, No, because the music store did not survey a sample that is representative of the population, is correct.
A valid survey must aim to avoid selection bias by ensuring that its sample represents the entire population it intends to make statements about.
Surveying only male customers introduces a bias, as it excludes female customers, making the sample not representative of all music store customers. This compromises the survey's ability to accurately reflect the preferences of the entire customer base.

1. The population of a town was 500 in 2010. The population grows at a rate of 9.6% annually.
(a) Use the exponential growth model to write an equation that estimates the population t years after 2010.
(a) Estimate the population of the town in 2020. Show your work.
We have been given that the population of a town was 500 in 2010. The population grows at a rate of 9.6% annually.
We will use exponential growth formula to solve our given problem.
[tex]y=a\cdot (1+r)^x[/tex], where,
y = Final amount,
a = Initial value,
r = Growth rate in decimal form,
x = Time.
Let us convert 9.6% into decimal as:
[tex]9.6\%=\frac{9.6}{100}=0.096[/tex]
We can see that initial value is 500.
[tex]y=500\cdot (1+0.096)^x[/tex]
[tex]y=500\cdot (1.096)^x[/tex]
Therefore, the equation [tex]P(t)=500\cdot (1.096)^t[/tex] represents the population t years after 2010.
To find the population of the town in 2020, we will substitute [tex]t=10[/tex] in our equation as:
[tex]P(10)=500\cdot (1.096)^{10}[/tex]
[tex]P(10)=500\cdot (2.5009530650806592)[/tex]
[tex]P(10)=1250.4765325403296\approx 1250[/tex]
Therefore, the population of the town would be approximately 1250 in 2020.

C. Jamie has positioned the ladder safely.
Step-by-step explanation:
A. In the figure attached length of ladder AC = 15 ft
and the top of the ladder is at the point A 14 ft above the ground.
B. SinC = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{14}{15}[/tex]
[tex]C=sin^{-1}(\frac{14}{15} )[/tex]
C = 68.96°
C ≈ 69°
C). For safety reasons, angle between the ladder and the ground should be less than 75°.
Existing angle between the ladder and ground is 69° which is less than the angle required for safety.
Therefore, Jamie has positioned the ladder safely.
