Distance around Pie = Pi*Diameter
Final answer:
The circumference of a 10-inch diameter cherry pie, using the value 3.1 for Pi, is 31 inches, which is the distance around the pie.
Explanation:
The distance around a circle is known as the circumference. To calculate the circumference of a 10-inch diameter cherry pie, we will use the relationship between the diameter and circumference, which involves Pi (π). The formula for the circumference C is C = π × d, where d is the diameter.
Using 3.1 as the approximate value for π, and with a diameter of 10 inches, we can calculate the circumference as follows:
C = π × d = 3.1 × 10 = 31 inches.
Therefore, the distance around a 10-inch cherry pie from Betsy's Bakery is approximately 31 inches.

When Elyse moved last weekend, the circular glass top for an end table broke. To replace it, she bought a circular glass top with a diameter of 20 inches.
What is the approximate area of the circular glass top Elyse bought?
Answer:
A = 314 inches^2
Step-by-step explanation:
We know the diameter of the glass. We need to find the radius
d = 2r
20 = 2r
Divide each side by 2
20/2 = 2r/2
10 =r
To find the area of the glass
A = pi r^2
A = pi * 10^2
A = pi*100
A = 100 *(3.14)
= 314 in^2

The area of a rectangle is (25x2 − 9y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work.
Answer:
(5x+3y) and (5x-3y)
Step-by-step explanation:
From the concept on difference between two squares;
a² - b² = (a+b)(a-b)
Therefore;
25x² - 9y² = (5x+3y) (5x-3y)
Therefore the dimensions of the square are (5x+3y) and (5x-3y)
Answer:
the dimensions of the rectangle are (5x + 3y) and (5x - 3y)
Step-by-step explanation:
The area of a rectangle is 25x^2 - 9y^2 square units.
To find the dimensions of a rectangle we need to factorize the expression completely.
We know that (a + b)(a - b) = a^2 - b^2
In this case: a^2 = 25x^2 and b^2 = 9y^2
So a = sqrt(25x^2) = 5x
And b = sqrt (9y^2) = 3y
Then the solution is:
(a + b)(a - b) = (5x + 3y)(5x - 3y)
Then the dimensions of the rectangle are (5x + 3y) and (5x - 3y)
Earth is approximately 9.3 × 107 miles from the sun. Saturn is approximately 8.87 × 108 miles from the sun. About how much farther is Saturn from the sun than Earth is?
Answers-
A)7.94 × 10 7 miles
B) 7.94 × 10 8 miles
C) 4.3 × 10 7 miles
D) 4.3 × 10 8 miles
Answer:
B) 7.94 × 10 8 miles
Step-by-step explanation:
Given
Distance between Earth and sun=E=9.3* 〖10〗^7 Miles
Distance Between Saturn and Sun=S=8.87* 〖10〗^8 Miles
In order to find the distance between Earth and Saturn, we have to subtract the distance between earth and sun from the distance between Saturn and sun. So
Distance between Earth and Saturn=S-E
=(8.87* 10^8 )-( 9.3* 10^7 )
As the distances are in scientific notation, to perform subtraction, the powers of 10 in both quantities have to be same, so
=(8.87*10* 10^7 )-(9.3* 10^7 )
=(88.7* 10^7 )-(9.3* 10^7)
=79.4* 10^7 Miles
It can also be written as:
Distance between Earth and Saturn=7.94* 10^8 Miles ..

130 | 1274
140 | 1372
the ratio weight to mass in contant. wich statemen describes the ratio of weight to mass and the value of x in the table?
A. 98/10; X =90
B. 98/10; =110
C. 10/98; X =90
D. 10/98; X= 110
Answer:
The statement which describes the ratio of weight to mass and the value of x is ⇒ 98/10 ; = 110 answer B
Step-by-step explanation:
* Lets explain how to solve the problem
- The mass (kilograms) values are
20 , 50 , x , 130 , 140
- The corresponding weight (newtons) values are
196 , 490 , 1078 , 1274 , 1372
* Lets find the ratio between weight to mass
∵ 196/20 ⇒ divide up and down by 2
∴ 196/20 = 98/10
∵ 490/50 ⇒ divide up and down by 10
∴ 49/5 ⇒ multiply up and down by 2
∴ 49/5 = 98/10
∴ 490/50 = 98/10
∵ 1274/130 ⇒ divide up and down by 13
∴ 1274/130 = 98/10
∵ 1372/140 ⇒ divide up and down by 14
∴ 1372/140 = 98/10
- All the ratios between weight to mass equal 98/10
∴ 1078/x = 98/10 ⇒ by using cross multiplication
∴ 98(x) = 1078(10)
∴ 98 x = 10780 ⇒ divide both sides by 98
∴ x = 110
* The statement which describes the ratio of weight to mass and the
value of x is 98/10; = 110
The ratio of weight to mass is constant. Write the ratio of weight to mass in simplest form to represent the table. Answer: 9.8
What should the value of x be in the table? Answer 110 kilograms

Find a unit vector in the direction of u and opposite of u
Just divide [tex]\mathbf u[/tex] by its magnitude:
[tex]\|\mathbf u\|=\sqrt{5^2+6^2+(-1)^2}=\sqrt{62}[/tex]
So a unit vector in the direction of [tex]\mathbf u[/tex] is
[tex]\dfrac{\mathbf u}{\|\mathbf u\|}=\dfrac5{\sqrt{62}}\,\mathbf i+\dfrac6{\sqrt{62}}\,\mathbf j-\dfrac1{\sqrt{62}}\,\mathbf k[/tex]
Then multiply this by -1 to get a unit vector pointing in the opposite direction.
To find the unit vector in the direction of a vector u, divide each component by its magnitude. For a vector u=i+j, the unit vector direction is ½(i+j), and the opposite direction is ½(-i-j).
Explanation:To find a unit vector in the direction of a given vector u, we must first calculate the magnitude (or length) of u and then divide each component of u by that magnitude. Let's assume the vector u has components i and j. The magnitude of u, denoted as |u|, is given by the square root of the sum of the squares of its components, which is √(i² + j²). The unit vector in the direction of u is then the vector u divided by its magnitude, Û = (i/|u|, j/|u|).
In the case of the vector u = i + j, the magnitude is √(1² + 1²) = √2, and so the unit vector in the direction of u is Û = ½(i + j). Conversely, the unit vector in the direction opposite to u would be Û = ½(-i - j) since we are simply negating each component of the unit vector in the direction of u.

solve for real numbers x.
Answer:
see explanation
Step-by-step explanation:
Inequalities of the type | x | > a always have solutions of the form
x < - a or x > a, thus
2x + 1 < - 5 OR 2x + 1 > 5 ( subtract 1 from both sides of both inequalities
2x < - 6 OR 2x > 4 ( divide both sides of both inequalities by 2 )
x < - 3 OR x > 2
What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?
Amplitude = −4; period = 2π; phase shift: x = -pie/2
Amplitude = −4; period = π; phase shift: x = pie/2
Amplitude = 4; period = π; phase shift: x = -pie/2
Amplitude = 4; period = 2π; phase shift: x = pie/2
Answer:
Amplitude = 4; period = π; phase shift: x = -pie/2
Step-by-step explanation:
For a sine wave of the following type:
y = Asin(Bx + C) + D, we have that:
A represents the amplitude
C represents the phase shift
D represents the vertical shift
And the period is given by: [tex]\frac{2 \pi}{B}[/tex]
Therefore, considering: f(x) = −4 sin(2x + π) − 5, we know that sin(a + π) = -sin(a). Then:
f(x) = −4 sin(2x + π) − 5 = 4sin(2x)-5 = 4cos(2x - π/2) - 5
The amplitude equals 4
The period is T = π
The fase shift is: -π/2.
Therefore, the correct option is:
Amplitude = 4; period = π; phase shift: x = -pie/2

Given: m∠MEJ=30°, m∠MFJ=50° , Find: Measurement of Arc KL & Measurement of Arc MJ
Answer:
Part a) The measurement of arc KL is [tex]20\°[/tex]
Part b) The measurement of arc MJ is [tex]80\°[/tex]
Step-by-step explanation:
Let
x--------> the measure of arc KL
y-------> the measure of arc MJ
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
[tex]m<MEJ=\frac{1}{2}(y-x)[/tex]
substitute the given value
[tex]30\°=\frac{1}{2}(y-x)[/tex]
[tex]60\°=(y-x)[/tex]
[tex]y=60\°+x[/tex] ------> equation A
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
[tex]m<MFJ=\frac{1}{2}(x+y)[/tex]
substitute the given value
[tex]50\°=\frac{1}{2}(x+y)[/tex]
[tex]100\°=(x+y)[/tex]
[tex]y=100\°-x[/tex] ------> equation B
Equate the equation A and B and solve for x
[tex]60\°+x=100\°-x[/tex]
[tex]2x=100\°-60\°[/tex]
[tex]x=20\°[/tex]
Find the value of y
[tex]y=100\°-20\°=80\°[/tex]
therefore
The measurement of arc KL is [tex]20\°[/tex]
The measurement of arc MJ is [tex]80\°[/tex]

Tim Tradesman pays $2,000 annually for $150,000 worth of life insurance. Answer the following questions. a. At the end of 10 years, how much will Tim have paid in premiums? b. At the end of 10 years, what will the cash value of his policy be? c. What will the ratio of cash value to premiums paid be (as a percent)?
____________________________________________________
Explanation for question A:
We are trying to found the amount of money he payed after 10 years.
He pays an annual (yearly) of $2,000, so we would just multiply 2,000 by 10, since we are trying to find the amount he point in 10 years, in which he pays $2,000 a year.
[tex]2000*10=20000[/tex]
Answer for Question A: Tim Tradesman paid $20,000 in premiums at the end of 10 years.
____________________________________________________
Explanation for question B:
In question B, we are trying to find the cash value of the policy at the end of 10 years.
To find the cash value at the end of 10 years, we would get the units of life insurance and multiply it by the cash value per unit
There would be 150 units of life insurance.
So we multiply:
[tex]150*89=13350[/tex]
Answer for Question B: The cash value of his policy will be $13,350 at the end of 10 years.
____________________________________________________
Explanation for question C:
In question C, we are trying to find the ratio of cash value to premiums paid.
Our cash value is 13,350 and we paid 20,000.
When you subtract 20,000 and 13,350, you would get 6,650.
[tex]20000-13350=6650[/tex]
Then when you add 20,000 and 13,350, you would get 33,350.
[tex]20000+13350=33350[/tex]
When you subtract 6,650 from 33,350, you would get 26,700
[tex]33350-6650=26700[/tex]
26,700 is 66.75% of 33,350.
Answer for Question c: The ratio as a percent for the cash value to premiums paid is 66.75%

Given that he polynomial function below find f(-9)
Answer:
B
Step-by-step explanation:
To find the value [tex]F(-9)[/tex] of the polynomial function [tex]F(x)=-x^2-10x-2,[/tex] you have simply substitute [tex]x=-9[/tex] into the function expression (write -9 instead of x):
[tex]F(-9)=-(-9)^2-10\cdot(-9)-2\\ \\=-81+90-2\\ \\=7[/tex]
Final answer:
To find f(-9) in the given function, substitute -9 for x and evaluate by following the transformation rules.
Explanation:
We can rewrite a given function as y = f{-2(x+1)}. To find f(-9), we substitute -9 for x in the function.
This gives us f(-9) = f{-2(-9+1)}. Calculating further results in f(-9) = f{-2(-8)}.
Therefore, to find f(-9), we evaluate the function at x = -8, and the value depends on the specific function provided.
