Answer:
y = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]
Step-by-step explanation:
The function is cubic
It has roots as -4, -4 , 6
this means the value of x = -4, -4 , 6 which makes the entire equation zero
so we have solutions as
x+4 = 0
x+4 = 0
x- 6 = 0
on forming a cubic equation using these
(x+4)(x+4)(x-6)
the equation passes through (2,36)
put x = 2
(2+4)(2+4)(2-6) = (6)*(6)*(-4)
which exceeds 36 so we product the equation with -1/4 to get 36
Final equation
y = [tex]\frac{-1}{4} (x+4)(x+4)(x-6)[/tex]
y = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]

Answer:
x = -1
Step-by-step explanation:
Putting the entire equation in decimal form, we have ...
2.1x + 1.8 = 0.3x
Subtracting 0.3x gives ...
1.8x +1.8 = 0
Dividing by 1.8, we get ...
x + 1 = 0
So, the solution is ...
x = -1 . . . . . . subtract 1 from both sides.
_____
Additional comment
Sometimes, when all of the numbers in the equation are divisible by the coefficient of x, it works out well to do that division before separating variables and constants. The other way this could have been solved is ...
subtract 1.8 ⇒ 1.8x = -1.8
divide by 1.8 ⇒ x = -1

Expression: [tex]\pi(\frac{D}{2})^{2}h-\pi(\frac{d}{2})^{2}h[/tex]
Volume: [tex]339.29cm^{3}[/tex]
Step-by-step explanation:
The formula for the volume of a cylinder is: [tex]\pi r^{2}h[/tex]. Since we are given the diameters instead of the radius, we divide the diameters by 2 to get the radius.
∴ The expression for the volume of the large cylinder after the hole was removed is [tex]\pi (\frac{D}{2})^{2}h - \pi(\frac{d}{2})^{2}h[/tex]
Approximate volume:
Substitute the numbers in:
[tex]\pi(\frac{8}{2})^{2}\times9-\pi(\frac{4}{2})^{2}\times9=339.29cm^{3}[/tex] (to the second decimal place)
∴ The volume of the big cylinder after removing the cylindrical hole is approximately [tex]339.29cm^{3}[/tex]
Find the circumference and the area of a circle with radius 7ft .
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.
Answer:
C=43.96 ft.
A=153.86 ft.^2
Step-by-step explanation:
for circumference, use C=2πr
for area, use A=π[tex]r^{2}[/tex]
The circumference and the area of a circle with radius 7 feet are 43.96 feet and 153.86 square feet, respectively.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
Given:
A circle with radius 7 feet.
Then the circumference of the circle,
= 2πr
= 2(3.14)(7)
= 43.96 feet.
The area of the circle,
= πr²
= (3.14) (49)
= 153.86 square feet.
Therefore, circumference is 43.96 feet and area is 153.86 square feet.

You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price. a. Write and solve an equation to find how much you spend on each CD. Let p represent the price you pay for each CD. Equation: =30.40 You spent $ on each CD. Question 2 b. The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs? No, you will not be able to buy 3 more CDs. Question 3 c. Explain your reasoning for part (b). Each CD costs $ at the regular price, so 3 CDs would cost $ .
Answer:
$7.6 ;
No, you will not be able to buy 3 more CDs
$9.5
$28.5
Step-by-step explanation:
Given that :
Cost of 4 CDs = $30.40
Cost per CD is equal
Sale price = 80% of original price
Price p per CD:
Cost of 4 CDs / number of CDs
$30.40 / 4
= $7.6
2)
No, you will not be able to buy 3 more CDs
If x = original price
80% of x = 7.6
0.8x = 7.6
x = 7.6 / 0.8
x = $9.5
$9.5 * 3 =$28. 5
Hence, $25 can't buy 3 CDs the next day (28.5 > $25)

If the radius of this Ferris wheel is 125 feet and the angle between each seat is 36°,
then what is the height of the Ferris wheel seat at point B if the bottom of the wheel is
20 feet off the ground? (Round to the nearest tenth)
Answer:
The height of the seat at point B above the ground is approximately 218.5 feet
Step-by-step explanation:
The given parameters are;
The radius of the Ferris wheel, r = 125 feet
The angle between each seat, θ = 36°
The height of the Ferris wheel above the ground = 20 feet
Therefore, we have;
The height of the midline, D = The height of the Ferris wheel above the ground + The radius of the Ferris wheel
∴ The height of the midline = 20 feet + 125 feet = 145 feet
The height of the seat at point B above the ground, h = r × sin(θ) + D
By substitution, we have;
h = 125 × sin(36°) + 145 ≈ 218.5 (The answer is rounded to the nearest tenth)
The height of the seat at point B above the ground, h ≈ 218.5 feet.

Find the coordinates of the point where y-4x=1 crosses the y axis
Answer:
(a) (-1/4,0)
(b) k = (10-c)/2
Step-by-step explanation:
(a) A point passing through the y-axis is the same as finding the y-intercept.
[Move terms to right-hand side; y = mx + b form]
y = 4x + 1
[Find x, when y = 0]
0 = 4x + 1
-1 = 4x
-1/4 = x
At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.
(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant
[Find x by plugging in known values]
Using y = 2x + c,
10 = 2k + c
10 - c = 2k
(10-c)/2 = k

Kate is 4 years older than Bob. If the sum of their ages is 28, what are the ages of
Kate and Bob?
Answer:
Kate is 16, Bob is 12
Step-by-step explanation:
Since Kate is 4 years older than Bob, Kate's age is represented by the following equation:
B+4=K
Bob's age is just B
Now, the sum of their ages is 28, which means we add Kate's and Bob's age:
Instead of writing K+B=28, we would write the equation with the same variable:
B+4+B= 28
(B+4= Kate's age)
add like terms
2b+4=28
subtract 4 from both sides
2b=24
divide by 2
b=12
12 is Bob's age and to find Kate's age, we add 4
Kate is 16.

Mr. Stokes bought 6 1/2 pounds of meat for a party. He used 2 1/4 pounds of meat to make tacos. The rest he used to make 1/4 pound burgers. How many burgers did Mr. Stokes make?
9514 1404 393
Answer:
17
Step-by-step explanation:
The remaining amount of meat is ...
6 1/2 - 2 1/4 = 4 1/4 = 17/4 . . . pounds
The number of 1/4 pound burgers that can be made with that amount of meat is ...
(17/4)/(1/4) = 17/1 = 17
Mr. Stokes made 17 burgers.
In ΔUVW, u = 44 inches, ∠W=56° and ∠U=117°. Find the length of v, to the nearest inch.
Answer:
The length of v is 6 inches
Step-by-step explanation:
Here, we want to calculate the length of v to the nearest inch
The best way to go about this is to use the sine rule
But before we proceed, we need the measure of angle V
Mathematically, since we have a triangle
W + U + V = 180
This is the sum of angles in a triangle
56 + 117 + V = 180
V = 180-56-117
V = 7 degrees
so we proceed to use sine rule to get the length of v
Mathematically;
v/Sin V = u/Sin U
Thus;
v/sin 7 = 44/sin 117
v = 44sin 7/sin 117
v = 6.018
This is approximately 6 inches

Emma is 10 years old. she asked her father how old he is. her father answered, "when you are my age I will be 70." how old is Emma's father.
Answer:
40
Step-by-step explanation:
Emma age: yE = 10 + x (x is timeline)
Father age: yF = A + x (x is timeline, A is Father age today)
in time x1: Emma will be A years old, and Father will be 70 years old.
yE (x1) = 10 + x1 = A
yF (x1) = A + x1 = 70
System of equations with unknown values: x1 and A.
substract equation 1 - equation 2:
10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40
So, father is 40 years old now
Emma's father is 40 years old
Let the age of Emma father be y
Age of emma = 10 years
In x years time;
Emma age will be 10 + xFathers age will be y + xIf in x1 years time, Emma will be y years old and his father will be 70 years old
Emma age: yE = 10 + x (x is timeline)
Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70
Solving both equations simultaneously;
10 - y = y - 70
10+70 = y + y
80 = 2y
2y = 80
y = 80/2
y = 40 years
Hence Emma's father is 40 years old
