Find the area of the shaded region.
Round to the nearest tenth
The area of the square is 36 squared inches, because it is a square with a side of 6 inches.
The two semicircles have a radius of 3 inches. If we subtract their areas from the area of the square, we have
[tex]36-2\left(\dfrac{\pi\cdot 3^2}{2}\right) = 36-9\pi[/tex]
The shaded region is half of this area, so the answer is
[tex]\dfrac{36-9\pi}{2} \approx 7.7[/tex]
36 minus 9 multiplied by Pi . Then divide that answer by 2 to get 7.7
what is
40π=5⁄18πr2
(5/18 is a fraction and 2 is an exponent)
r1 = -12 and r2 = 12
[tex]\bf 40\pi =\cfrac{5}{18}\pi r^2\implies 40\pi =\cfrac{5\pi r^2}{18}\implies 720\pi =5\pi r^2\implies \cfrac{720\pi }{5\pi }=r^2 \\\\\\ 144=r^2\implies \sqrt{144}=r\implies 12=r[/tex]
3m + n =7
m + 2n = 9
Answer:
n = 4, m = 1
Step-by-step explanation:
Given the 2 equations
3m + n = 7 → (1)
m + 2n = 9 → (2)
Rearrange (2) expressing m in terms of n, by subtracting 2n from both sides
m = 9 - 2n → (3)
Substitute m = 9 - 2n into (1)
3(9 - 2n) + n = 7 ← distribute left side
27 - 6n + n = 7 ← simplify left side
27 - 5n = 7 ( subtract 27 from both sides )
- 5n = - 20 ( divide both sides by - 5 )
n = 4
Substitute n = 4 into (3) for corresponding value of m
m = 9 - (2 × 4) = 9 - 8 = 1
Thus m = 1 and n = 4

Leah loves chicken wings and is comparing the deals atThree different restaurants Buffalo Bills has eight wings for seven dollars Buffalo wild wings have 12 wings for $10 fingers has 20 wings for $17 which restaurant offers the lowest price per wing
Buffalo Bills has the lowest price per wing. To find the answer divide the number of wings by the price to see how much it is per wing.
Buffalo Wild Wings offers the lowest cost per wing at $0.833, compared to $0.875 at Buffalo Bills and $0.85 at Fingers.
Buffalo Bills: 8 wings for $7 means $7 ÷ 8 wings = $0.875 per wing.Buffalo Wild Wings: 12 wings for $10 means $10 ÷ 12 wings = $0.833 per wing.Fingers: 20 wings for $17 means $17 ÷ 20 wings = $0.85 per wing.Comparing these values, Buffalo Wild Wings offers the lowest cost per wing at $0.833.
find the distance between the points (0,8) amd (8,5)
Answer:
[tex]d=\sqrt{73}[/tex]
Step-by-step explanation:
Use the distance formula.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Plug in the points.
8 - 0 = 8
8^2 = 64
5 - 8 = -3
-3^2 = 9
64 + 9 = 73
[tex]d=\sqrt{73}[/tex]
Evaluate 3C1.
a)3
b)1
c)2
d)6
Answer: Option a) 3
Step-by-step explanation:
The formula for calculating combinations is as follows
[tex]nCr = \frac{n!}{r!(n-r)!}[/tex]
Where "n" is the amount of items in a set and you can choose "r" from them
3C1 reads as: The combination of 1 in 3. You have a set of 3 elements and choose 1 of them.
[tex]n = 3\\\\r = 1[/tex]
So :
[tex]3C1=\frac{3!}{1!(3-1)!}\\\\3C1=\frac{3!}{1!*2!}\\\\3C1=\frac{3*2*1}{1*2*1}\\\\3C1=3[/tex]
if Lylah completes the square for f(x)=x squared -12x+7 in order to find the minimum she must write f(x) in the general form f(x)=(x-a)squared +b what is the value of a for f(x)? A. 6 B. -6 C. 12 D. -12
Answer:
A. 6
Step-by-step explanation:
f(x) = x² − 12x + 7
To complete the square, we first factor the leading coefficient to make it 1 (which it already is).
Then, we take half the second coefficient, square it, and then add to both sides. So (-12/2)² = (-6)² = 36.
f(x) + 36 = x² − 12x + 36 + 7
Then we factor the perfect square:
f(x) + 36 = (x − 6)² + 7
Then solve for f(x) by subtracting and simplifying:
f(x) = (x − 6)² + 7 − 36
f(x) = (x − 6)² − 29
So the value of a is 6.

what two numbers add to 5 and multiply to -3
Answer:
[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex] and [tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]
[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex] and [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
Step-by-step explanation:
Let the numbers be x and y.
We now have a system of equations.
x + y = 5
xy = -3
Solve the second equation for x.
x = -3/y
Now substitute x in the first equation with -3/y.
-3/y + y = 5
Multiply both sides by y.
-3 + y^2 = 5y
y^2 - 5y - 3 = 0
Use the quadratic formula to solve for y.
[tex] y = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] y = \dfrac{-(-5) \pm \sqrt{(-5)^2 - 4(1)(-3)}}{2(1)} [/tex]
[tex] y = \dfrac{5 \pm \sqrt{25 + 12}}{2} [/tex]
[tex] y = \dfrac{5 \pm \sqrt{37}}{2} [/tex]
[tex] y = \dfrac{5 + \sqrt{37}}{2} [/tex] or [tex] y = \dfrac{5 - \sqrt{37}}{2} [/tex]
[tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex] or [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
We get 2 solutions for y. Now for each solution for y, we need to find a corresponding solution for x.
Solve the first equation for x.
x + y = 5
x = 5 - y
Substitute each y value to find the corresponding x value.
[tex] x = 5 - (\dfrac{5}{2} + \dfrac{\sqrt{37}}{2}) [/tex]
[tex] x = 5 - \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
[tex] x = \dfrac{10}{2} - \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
This give one solution as:
[tex] x = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex] and [tex] y = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]
Now we substitute the other y value to find the other x value.
[tex] x = 5 - (\dfrac{5}{2} - \dfrac{\sqrt{37}}{2}) [/tex]
[tex] x = 5 - \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]
[tex] x = \dfrac{10}{2} - \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]
[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex]
This give the second solution as:
[tex] x = \dfrac{5}{2} + \dfrac{\sqrt{37}}{2} [/tex] and [tex] y = \dfrac{5}{2} - \dfrac{\sqrt{37}}{2} [/tex]
How many solutions can be found for the linear equation?
3(x + 4) = 3x + 4
None.
Distribute the 3 to the (x + 4) to get 3x + 12.
Subtract 3x from both sides to get 12 = 4.
This is not true, so there are no solutions.

Answer:
The variation equation is
[tex] f = \frac{k.m_1.m_2}{ {r}^{2} } [/tex]
step-by-step explanation:
From the question, the two masses are
[tex]m_1 \: and \: m_2[/tex]
This implies that the product of the two masses
[tex] = m_1 \times m_2 = m_1.m_2[/tex]
Moreover, the force,f varies directly with the products of the two masses
[tex] \implies \: f\propto m_1.m_2....eqn.1[/tex]
Also, the force varies inversely with the square of the distance,r
[tex] \implies \: f\propto \frac{1}{ {r}^{2} }.......eqn.2[/tex]
Joining equation 1 and 2, we got
[tex] \implies \: f\propto \frac{1}{ {r}^{2}} \times m_1.m_2[/tex]
[tex] \implies \: f \propto\frac{m_1.m_2}{ {r}^{2}}[/tex]
But the constant of variation is k
Multiplying the right hand side of the equation by k, we got
[tex] \implies \:f=\frac{k.m_1.m_2}{ {r}^{2}}[/tex]

Answer:
This is exponential growth
Step-by-step explanation:
The amount by which the function is increasing from point to point is increasing, so it must be a quadratic or exponential function. If it was a quadratic, the amount it increases by would be increasing by a steady amount. (Ex. x^2 increases by how much it increased the last time + 2). But because this is not what the data shows, the function must be exponential.
Answer: Exponential

You can choose from three types of sandwiches for lunch and three types of juice. How many possible lunch combinations of sandwich and juice can you have?
Answer:
9
Step-by-step explanation:
The number of possible lunch combinations of sandwich and juice are 9.
If we have to choose r objects out of n objects and then arrange them among themselves, then we first choose the objects in ⁿCr ways and then arrange them in ways.
This can be used to find the number of different combinations possible of the sandwiches and juices.
Ways to select the sandwiches from 3 options = ³C₁ = 3!/1!(3-1)!
Ways to select the juice from 3 options = ³C₁ = 3!/1!(3-1)!
= ³C₁ = 3!/1!(3-1)!
Now, the total types of possible lunch combinations that can be created as 3×3=9
Hence, the number of possible lunch combinations of sandwich and juice are 9.

the number of apple s juan eats and the numbers of hours he sleep each night represents what type of correlation
Positive
Median
Negative
No correlation
Answer:
No correlation
Step-by-step explanation:
With the information provided, we have to conclude there is no correlation, since there is no apparent link between the two information.
It would be a positive correlation for example if we knew that the more apples Juan eats, the more he sleeps (or vice-versa).
It could be a negative correlation if we found that the more apples he eats, the less hours of sleep he has (or vice-versa).
But in this instance, we don't have any data indicating there is any form of correlation between those two numbers.

x = -6+7 x = -6-7
x = 1 x = -13
According to synthetic division below, which of the following statements are true ?
ANSWER
C
E
F
EXPLANATION
The result of the synthetic division is :
3 -1 0
The last number is the remainder which is 0
The first two numbers are the coefficients of the quotient.
Therefore the quotient is 3x -1
Since the remainder is 0, x-4 is a factor of
[tex]f(x) = 3 {x}^{2} - 13x + 4[/tex]
This also means that:
[tex](3 {x}^{2} - 13x + 4) \div (x - 4) = 3x - 1[/tex]
This again means that x=4 is a root of
[tex]f(x) = 3 {x}^{2} - 13x + 4[/tex]
The correct choices are C,E and F.

if f(x) = 4x + 3 and g(x) = √x-9 ,
which statement is true?
A.) 2 is in the domain of f ° g
B.) 2 is NOT in the domain of f ° g
Answer: Option B
2 is NOT in the domain of f ° g
Step-by-step explanation:
First we must perform the composition of both functions:
If [tex]g(x) = \sqrt{x-9}[/tex] and not [tex]\sqrt{x} -9[/tex]
[tex]f (x) = 4x + 3\\\\g (x) = \sqrt{x-9}\\\\f (g (x)) = 4 (\sqrt{x-9}) + 3[/tex]
The domain of the composite function will be all real numbers for which the term that is inside the root is greater than zero. When x equals 2, the expression within the root is less than zero
[tex]f (g (x)) = 4 (\sqrt{2-9}) + 3\\\\f (g (x)) = 4 (\sqrt{-7}) + 3[/tex]
The root of -7 does not exist in real numbers, therefore 2 does not belong to the domain of f ° g
The answer is Option B.
Note. If [tex]g(x) = \sqrt{x}-9[/tex]
So
[tex]f(g(x)) = 4(\sqrt{x})-36 + 3[/tex] And 2 belongs to the domain of the function
