Find the area to the nearest square foot of the shaded region below, consisting of a square with a circle cut out of it. Use 3.14 as an approximation for π. Need this ASAP
Answers
Answer:
22 square feet
Step-by-step explanation:
Area of shaded region = Area of square - Area of circle. The diameter of the circle is also the length of the side of the square as the circumference of the circle is on the circumference of the square.
Area of circle = 3.14 × r × r
r = 10 ÷ 2
= 5
Area of circle = 3.14 × 5 × 5
= 78.5
Area of square = length × length
Area of square = 10 × 10
= 100
Area of shaded region = Square - Circle
= 100 - 78.5
= 21.5
= 22 (to the nearest square foot)

Find the value of x in the equation below. 2x+8/6=1/3(x+4) A. x = 0 B. no real solutions C. infinitely many solutions D. x = 1
Answers
Answer:
x = 0
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x+8/6-(1/3*(x+4))=0
Simplify 1/3
Equation at the end of step 1 :
(2x + 8/6) - (1/3 * (x + 4)) = 0
STEP 2 :
Equation at the end of step 2
(2x + 8/6) - (x+4)/3 = 0
STEP 3 :
Simplify 4/3
Equation at the end of step 3 :
(2x + 4/3) - (x+4)/3 = 0
STEP 4 :
Rewriting the whole as an Equivalent Fraction
Adding a fraction to a whole
Rewrite the whole as a fraction using 3 as the denominator :
2x = 2x/1 = 2x*3/3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2x * 3 + 4/3 = 6x+4/3
Equation at the end of step 4 :
(6x+4)/3 - (x+4)/3 = 0
STEP 5 : Pulling out like terms
Pull out like factors :
6x + 4 = 2*(3x + 2)
Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2*(3x+2)-((x+4))/3 = 5x/3
Equation at the end of step 5 :
5x/3 = 0
STEP 6: When a fraction equals zero
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator, multiply both sides of the equation by the denominator.
Here's how:
5x/3*3 = 0*3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5x = 0
Solving a Single Variable Equation:
Solve : 5x = 0
Divide both sides of the equation by 5:
x = 0

Answers
Answer:
A. r = ∛ 15V / 2π
Step-by-step explanation:
Volume of a sphere = 4/3 π r³
And to be divided into 10 equal wedges parts.
Volume of each wedge = V = 2/15 π r³
find r
V = 2 π r³ / 15
15 V = 2 π r³
15V / 2π = r³
r = ∛ 15V / 2π
The correct option will be option A i.e., r = [tex]\sqrt[3]{\frac{15}{2\pi } }[/tex]
It is given that a solid sphere is cut into 10 equal wedges , with each wedge having volume V = [tex]\frac{2}{15} \pi r^{3}[/tex]
We have to solve it to get the value of radius r.
What is the formula for volume of sphere ?
The volume of sphere is given by V = [tex]\frac{4}{3} \pi r^{3}[/tex] where , r is the radius of the sphere.
As per the question ;
Volume of sphere = [tex]\frac{4}{3} \pi r^{3}[/tex]
To be divided into 10 equal wedges ;
Volume of each wedge of sphere will be ;
V = [tex]\frac{2}{15} \pi r^{3}[/tex]
15 V = 2[tex]\pi r^{3}[/tex]
or
r³ = [tex]\frac{15V}{2\pi }[/tex]
or
r = [tex]\sqrt[3]{\frac{15}{2\pi } }[/tex]

What percentage of the data in a standard normal distribution lies between x = .09 and x = 1.2?
Answers
Answer:
34.9% of the data in a standard normal distribution lies between x = .09 and x = 1.2.
Step-by-step explanation:
We have to find the percentage of the data in a standard normal distribution that lies between X = 0.09 and X = 1.2.
As we know that the mean and the standard deviation of a standard normal distribution is 0 and 1 respectively.
The z-score probability distribution for the standard normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] = [tex]\frac{X-0}{1}[/tex] ~ Standard normal
Now, the percentage of the data in a standard normal distribution that lies between X = 0.09 and X = 1.2 is given by = P(0.09 < X < 1.2)
P(0.09 < X < 1.2) = P(X < 1.2) - P(X [tex]\leq[/tex] 0.09)
P(X < 1.2) = P( [tex]\frac{X-0}{1}[/tex] < [tex]\frac{1.2-0}{1}[/tex] ) = P(Z < 1.2) = 0.8849
P(X [tex]\leq[/tex] 0.09) = P( [tex]\frac{X-0}{1}[/tex] [tex]\leq[/tex] [tex]\frac{0.09-0}{1}[/tex] ) = P(Z [tex]\leq[/tex] 0.09) = 0.5359
The above probabilities are calculated by looking at the value of z = 1.2 and x = 0.09 in the z table which has an area of 0.8849 and 0.5359 respectively.
Therefore, P(0.09 < X < 1.2) = 0.8849 - 0.5359 = 0.349.
Find the unit vector in the direction of (4,-4). Write your answer in component form. Do not approximate any numbers in your answer.
Answers
Answer:
[tex](\frac{1}{\sqrt{2} }, \frac{-1}{\sqrt{2} } )[/tex]
Step-by-step explanation:
The unit vector for a nonzero vector, say u, in the direction of u is given by:
û = [tex]\frac{u}{|u|}[/tex] ---------------(i)
Where;
|u| = magnitude of vector u
From the question;
u = (4, -4)
First let's calculate the magnitude of u as follows;
|u| = [tex]\sqrt{(4)^2 + (-4)^2}[/tex]
|u| = [tex]\sqrt{16 + 16}[/tex]
|u| = [tex]\sqrt{32}[/tex] = [tex]4\sqrt{2}[/tex]
Now, substitute u and |u| into equation (i) as follows;
û = [tex]\frac{(4, -4)}{4\sqrt{2} }[/tex]
û = [tex](\frac{4}{4\sqrt{2} }, \frac{-4}{4\sqrt{2} } )[/tex]
û = [tex](\frac{1}{\sqrt{2} }, \frac{-1}{\sqrt{2} } )[/tex]
Therefore, the unit vector is [tex](\frac{1}{\sqrt{2} }, \frac{-1}{\sqrt{2} } )[/tex]

in abc the measure of side c is 3.9cm if def has a dilation of abc with a scale factor of 2.5
Answers
Complete Question:
In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f
Answer:
f = 9.75
Step-by-step Explanation:
From the information given, a sketch of ∆ABC and ∆DEF with their corresponding sides and angles have been attached below.
∆DEF is a dilation of ∆ABC, which is said to be on a scale factor of 2.5.
The scale factor is a whole number, this implies that ∆DEF is an enlargement of ∆ABC.
Since side c = 3.9 cm, in ∆ABC corresponds to side f, in ∆DEF, therefore, the measure of f would be:
f = measure of c × scale factor
f = 3.9 cm × 2.5
f = 9.75

Formulate the quadratic function that contains the points (-2,1), (0,1) and (1,4).
o f(x) = x2 + 2x +1
Of(x) = x2 - 2x + 1
Of(x) = x2 - 2x - 1
o f(x) = x2 + 2x - 1
Answers
Answer: A) f(x) = x² + 2x + 1
Step-by-step explanation:
The standard form of a quadratic equation is: y = Ax² + Bx + C
Input (x, y) coordinates into the standard equation to solve for A, B, & C.
(0, 1) → 1 = A(0)² + B(0) + C
1 = C
(-2, 1) → 1 = A(-2)² + B(-2) + C
1 = 4A - 2B + 1
0 = 4A - 2B
(1, 4) → 4 = A(1)² + B(1) + C
4 = A + C + 1
3 = A + B
Solve the system of equations:
0 = 4A - 2B → 1(0 = 4A - 2B) → 0 = 4A - 2B
3 = A + B → 2(3 = A + B) → 6 = 2A + 2B
6 = 6A
1 = A
Input A = 1 into either equation to solve for B:
3 = A + B
3 = 1 + B
2 = B
Now, Input A = 1, B = 2, and C = 1 into the standard equation:
y = (1)x² + (2)x + (1)
y = x² + 2x + 1

Answer:
Sum of the sequence (Sn) = 33,859
Step-by-step explanation:
Given:
Sequence = 685+678+671+664+...+6
Find:
Sum of the sequence (Sn)
Computation:
a = 685
d = 678 - 985 = -7
an = 6
an = a+(n-1)d
6 = 685+(n-1)(-7)
-679 = (n-1)(-7)
97 = n-1
n = 98
So,
Sum of the sequence (Sn) = (n/2)[a+an]
Sum of the sequence (Sn) = (98/2)[685+6]
Sum of the sequence (Sn) = (49)(691)
Sum of the sequence (Sn) = 33,859
