What is the approximate area of the circle shown below?
A. 26.4 in2
B. 55.4 in 2
c. 13.2 in2
D. 222 in2
Hey there!
Formula: πr^2
r = radius
pi = 3.1415926535898 (but we can say it approximately equals 3.14)
Your equation (3.14)(4.2)^2 = answer
4.2^2 = 4.2 × 4.2 = 17.64
New equation: 17.64 × 3.14 = 55.3896
We round our answer to the nearest tenth
Answer: 55.4 ☑️
Good luck on your assignment and enjoy your day!

Determine whether the function given by the table is linear, exponential, or
neither. If the function is linear, find a linear function that models the data; if it is
exponential, find an exponential function that models the data.
Answer:
It's A and the answer is 4^x
Step-by-step explanation:
The exponential function that models the data is f(x) = [tex]4^x[/tex].
What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.
We have a table.
The given function is not a linear because the difference of two consecutive term is not constant.
Now, the ratio
1/(1/12)= 12
12/1= 12
144/12= 12
1728/ 144= 12
If the ratio is same then the function is Exponential.
So, the exponential function is
f(x) = [tex]4^x[/tex]

What is the y-value that goes with an x-value of 5?
Answer: y = 7- 5x
Step-by Step Explanation: The variable x is multiplied by a larger value here; it's multiplied by 5. So I should expect that my y-values will grow fairly quickly. This means that I should expect a fairly "tall" graph.
First I'll do the T-chart.
T-chart
This equation is an example of a situation in which you will probably want to be particular about the x-values you pick. Because the x is multiplied by a relatively large value, the y-values grow quickly. For instance, you probably wouldn't want to use x = 10 or x = –7 as inputs. You could pick larger x-values if you wished, but your graph would very quickly get awfully tall.
I can see, from my T-chart, that my y-values are getting pretty big on either end (that is, in the positive numbers above the horizontal axis, and in the negative numbers below). I don't want to waste time computing points that will only serve to make my graph ridiculously large, so I'll quit with what I've got so far. But I'm glad I plotted more than just two points, because lines that start edging close to vertical can easily go wrong, if I'm not neat in my work.
Here's my graph:
y = 7 - 5x
Exponential functions do not form straight lines.

how to solve x=2y and 6y-3x=18 by using subsitution
Answer:
This system of equations has no solutions
Step-by-step explanation:
in the linear equations, if the variable is disappeared, and
The two sides of the equation are equal, then the equation has infinitely many solutionsThe two sides of the equation are not equal, then the equation has no solutionsLet us solve the question
∵ x = 2y ⇒ (1)
∵ 6y - 3x = 18 ⇒ (2)
→ Substitute x in equation (2) by the value of x in equation (1)
∵ 6y - 3(2y) = 18
∴ 6y - 6y = 18
∴ 0 = 18
→ 0 can not equal 18
∴ Left hand side ≠ Right hand side
→ From the 2nd note above
∴ This system of equations has no solutions

Which ratio is equal to 15:20?
a: 5:10
b: 18:25
c:21:28
d: 24:30
Answer:
C - 21:28
Step-by-step explanation:
this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.
For C I did this:
Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.
Let's test it out for the numerator now. 21 ÷ 15 = 1.4.
So there's your answer.

Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.
(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)
Write an equation of the line in slope-intercept form that contains
(-3, 13) and (6,-5)
Answer:
[tex]y = -2x +7[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-3,13)[/tex]
[tex](x_2,y_2) = (6,-5)[/tex]
Required
Determine the equation in slope intercept form
First, we calculate the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
The equation becomes:
[tex]m = \frac{-5 - 13}{6 - (-3)}[/tex]
[tex]m = \frac{-5 - 13}{6 +3}[/tex]
[tex]m = \frac{-18}{9}[/tex]
[tex]m = -2[/tex]
The equation is then calculated using:
[tex]y -y_1 = m(x - x_1)[/tex]
Substitute values for y1, m and x1
[tex]y - 13 = -2(x -(-3))[/tex]
[tex]y - 13 = -2(x +3)[/tex]
[tex]y - 13 = -2x -6[/tex]
Make y the subject
[tex]y = -2x - 6 + 13[/tex]
[tex]y = -2x +7[/tex]

Answer:
Slope: -2/3
Y-intercept: (0, 9)
Equation: y = -x + 9
3 blocks away: 6 visits
Step-by-step explanation:
Calculate slope from point (1, 8) to point (3, 7) on the line.
The y-intercept is where the line meets the y-axis.
The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.
Check the point on the line where x = 3.

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
40.5%
74%
54.8%
99.8%
22.2%
The apprοximate prοbability that Ankit will make all three shοts is 0.405 οr 40.5%. Thus, option a is correct.
What is binοmial distributiοn?A prοbability distributiοn knοwn as the binοmial distributiοn is used tο characterize the number οf successes in a certain number οf independent trials, where each trial has οnly οne οf twο pοtential οutcοmes (success οr failure) and the chance οf success is cοnstant acrοss all trials. Fοr determining the likelihοοd οf achieving a certain number οf successes in a set number οf trials, it is utilised.
Given, Ankit makes 74% οf the free thrοws.
Using binοmial distributiοn we have:
[tex]$\rm P(X=k)= (^nC_k) \times p^{k} \times (1-p)^{(n-k)}$[/tex]
Fοr k = 3 we have:
[tex]$ \rm P(X=3)=(^3C_3) \times 0.74^{3} \times (1-0.74)^{(3-3)}$[/tex]
[tex]$ \rm P(X=3)=0.74^{3}$[/tex]
P(X=3) ≈ 0.405
Hence, the apprοximate prοbability that Ankit will make all three shοts is 0.405 οr 40.5%.
