C = 2*pi*r
C = pi*d
C = 125.6
r = d/2
Solution
C = pi *d
125.6 = 3.14 * d Divide both sides by 3.14
125.6/3.14 = d
d = 40
You can use 1 of 2 methods to get the radius
The easiest one is use
r = d/2
r = 40/2
r = 20
Carl wrote three numbers beetween 0.48 and 0.49, what numbers could carl have written
Answer:
0.481, 0.487653287..,. and 0.48953
Step-by-step explanation:
There is no way I could know what numbers Carl has writen because there is an uncountably infinite number of numbers Carl could have written. But if I had to guess it would be 0.481, 0.487653287... and 0.48953

Three consecutive integers have a sum of 72. Find the integers.
Answer:
Step-by-step explanation:
x is smallest integer
x + (x + 1) + (x + 2) = 72
3x + 3 = 72
3x = 69
x = 23.
This means that the integers are 23, 24, and 25.

find the x and y intercept of the graph of -9x+3y=12
Step-by-step explanation:
by graph method
x = -b/2a
b = 3, a = -9
x = -3/-18
x = 1/6
back to the equation to substitute
-9x + 3y = 12
-9(1/6) + 3y = 12
- 3/2 + 3y = 12
-3 + 6y = 24
6y = 27
y = 9/2
x = 1/6, y = 9/2

I need help ASAP
Answer:
Stem and leaf plot.
Step-by-step explanation:
The stem and leaf plot is the most appropriate way because it has lots of different values, and they can be grouped according to their tens place. Also, a line graph would have too many values in this situation to be feasible.

Answer:
The circumference of the circle is 31.4 yd.
Step-by-step explanation:
From the question,
We are to determine the circumference of a circle whose diameter is 10 yd.
The formula for calculating the circumference of a circle in terms of diameter is given as
C = πd
Where C is the circumference
and d is the diameter
From the given information
d = 10 yd
and π = 3.14
Putting the parameters into the formula
We get,
C = 3.14 × 10
∴ C = 31.4 yd
Hence, the circumference of the circle is 31.4 yd.
Let f (t) be the number of people, in millions, who own cell phones t years after 1990. Explain the meaning of the following statement.
f (10) = 110.3
Answer:
10 years after 1990 (or in the year 2000) there are 110.3 million people who own cell phones.
Step-by-step explanation:
t= 10 years after 1990.
We are given that f(t) is # of people in millions who own cell phones.
f(10) = 110.3 implies in 10 years after 1990, there are 110.3 million people who owned cell phones.
Given that,
Let f (t) be the number of people, in millions, who own cell phones t years after 1990. To explain the meaning of the following statement, f (10) = 110.3
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
f (t) be the number of people, in millions, who own cell phones t years after 1990.
f(10) = 110.3
Implies,
In 10 years after 1990, there are 110.3 million people who owned cell phones.
Thus, f(10) = 110.3 implies in 10 years after 1990, there are 110.3 million people who owned cell phones.

Find the value of x and y.
Given that f(x) = x2 + 12x + 35 and g(x) = x + 7, find (f:g)(x) and express
the result in standard form.
Answer:
x^3+19x^2+119x+245
Step-by-step explanation:
The required value of function (f:g)(x) would be (x + 5) which is the ratio of function f(x) and g(x).
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
Given that f(x) = x² + 12x + 35 and g(x) = x + 7
As per the question,
⇒ (f:g)(x) = (x² + 12x + 35) : (x + 7)
⇒ (f:g)(x) = (x² + 12x + 35) / (x + 7)
Solve the above quadratic equation, and we get
⇒ (f:g)(x) = (x² + 5x + 7x + 35) / (x + 7)
⇒ (f:g)(x) = x(x + 5) + 7(x + 5) / (x + 7)
⇒ (f:g)(x) = (x + 5)(x + 7) / (x + 7)
⇒ (f:g)(x) = (x + 5)
Therefore, the required value of function (f:g)(x) would be (x + 5).

What is the missing base of 16=____ to the power of 4?
A data set is given as follows:
Please give the best fit using the least squares with the following functions
(1) y = ax + b;
(2) y = ax + b;
and draw their respective graphs.
(Probability and Statistics)
Entering the values obtained from the data in the table based on the
given functions of y = a·x + b, and y = a·|x| + b, we have;
(1) y = -0.0614·x + 1.58772
(2) y = 0.3824·x + 0.91168
How can the best fit lines be obtained?The least squares regression formula is presented as follows;
[tex]a = \mathbf{\dfrac{\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) }{\sum \left(x_i - \bar x\right )^2 }}[/tex]
(1) From the data in the table, and by using MS Excel, we have;
[tex]\overline x[/tex] = -0.2
[tex]\overline y[/tex] = 1.6
[tex]\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right)[/tex] = -1.4
[tex]\sum \left(x_i - \bar x\right )^2[/tex] = 22.8
Which gives;
[tex]a = \dfrac{-1.4}{22.8 } \approx \mathbf{-0.0614}[/tex]
1.6 ≈ b - 0.0614 × (-0.2)
b = 1.6 - 0.0614 × (0.2) = 1.58772
The equation of best fit for the function, y = a·x + b, is therefore;
y = -0.0614·x + 1.58772(2) For the function, y = a·|x| + b, we have;
[tex]\overline x[/tex] = 1.8
[tex]\overline y[/tex] = 1.6
[tex]\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right)[/tex] = 2.6
[tex]\sum \left(x_i - \bar x\right )^2[/tex] = 6.8
Which gives;
[tex]a = \dfrac{2.6}{6.8} \approx \mathbf{0.3824}[/tex]
1.6 ≈ b + 0.3824 × (1.8)
b = 1.6 - 0.3824 × (1.8) = 0.91168
The equation of best fit for the function, y = a·|x| + b, is therefore;
y = 0.3824·x + 0.91168Learn more about the least squares regression line here:
