Answer:
Step-by-step explanation:
(x - y)² = x² - 2xy + y²
x = b ; y = 3
(b - 3)² = b² - 2 *b * 3 + 3²
= b² - 6b + 9
How do you find the base of a cylinder?
Answer:
A cylinder is a solid figure with two parallel circles of the same size at the top and bottom. The top and bottom of a cylinder are called the bases. The height h of a cylinder is the distance between the two bases.
Step-by-step explanation:
Formula: Since the base of a cylinder is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.

what is meant by inertia
Answer:
Inertia is a tendency to do nothing or to remain unchanged.
It is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line unless that state is changed by an external force.
Answer:
Inertia is the resistance to a change in motion.
Therefore, an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by an unbalanced/external force.

Which graph represents a proportional relationship?
I think its A
Answer:
If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph

Step-by-step explanation:
The scale drawing has width 8 in. and length 12 in.
The scale is 1 in. = 1.5 ft
To find the real linear dimensions, multiply the scale dimension by 1.5 and change from inches to feet.
The real width is 8 * 1.5 ft = 12 ft
The real length is 12 * 1.5 ft = 18 ft
The scale area is 8 in. * 12 in. = 96 sq in.
The real area is 12 ft * 18 ft = 216 sq ft
The scale perimeter is 2(8 in. + 12 in.) = 40 in.
The real perimeter is 2(12 ft + 18 ft) = 60 ft
Now we look at the statements.
A) True
B) True
C) True
D) False
E) True

Write the probabilities below in their simplest form.
What is the probability of her getting an orange?
Total fruit: 6 + 4 +2 = 12
Probability of Picking a banana is 6/12 = 1/2
Probability pf picking apple is 4/12 = 1/3
Probability of picking orange is 2/12 / 1/6
Picking an orange = 1/6
Answer:
Solution :-Probability of getting banana = 6/12 = 1/2
Probability of getting apples = 4/12 = 1/3
Probability of getting orange = 2/12 = 1/6

±√121 what is the answer
Answer:
±√121 = ±11 (11, -11)
Step-by-step explanation:
1.First, find two equal numbers multiplied by each other to get 121:
This will be 11×11, so the answer for the square root is +11 or -11.
2. Or you can find the square root of a number using this method:
draw a line splitting two sides from each other.then, write the number inside the square root on the left side of the line.after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).write the answer to the division on the left side of the line.next, rewrite the two steps above by writing a number that can be divided by the answer of the division.stop writing the number when you get to number one on the left and right sides.finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.you can understand it more from the picture below, I also did another example for this method.An employee of MetaChem earned $5,440 commission for selling $128,000 in merchandise. What was

Answer:
commission rate = 4.25%

The complete table of the values for the equation y = 4x + 9 is;

What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation is,
⇒ y = 4x + 9
Now,
Solve the equation for the values of x as;
The given values for x are;
x = - 2, - 1, 0 , 1 , 2
So, Find the value of y as;
Substitute x = - 2 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × - 2 + 9
⇒ y = - 8 + 9
⇒ y = 1
Substitute x = - in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × - 1 + 9
⇒ y = - 4 + 9
⇒ y = 5
Substitute x = 0 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 0 + 9
⇒ y = 0 + 9
⇒ y = 9
Substitute x = 1 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 1 + 9
⇒ y = 4 + 9
⇒ y = 13
Substitute x = 2 in the equation we get;
⇒ y = 4x + 9
⇒ y = 4 × 2 + 9
⇒ y = 8 + 9
⇒ y = 17
Thus, The complete table of the values for the equation y = 4x + 9 is;
x - 2 - 1 0 1 2
y 1 5 9 13 17

. A solid metal cylinder of radius 5 cm and height 12 cm is melted down and recast into a
cone of base radius 10 cm.
Calculate the height of the cone.
Answer:
H = 9 cm
Step-by-step explanation:
The volume of the cylinder equal the volume
[tex]\pi\: \: {r}^{2} \times hcy = \frac{1}{3} \pi {r}^{2} \times hco \\ hco = 9 \: cm[/tex]
The height of the cone is 9 cm.
The volume of the cylinder = The volume of the Cone
This is because the exact metal cylinder was recast into a cone.
Volume of a cylinder:volume = πr²h
r = 5 cm
h = 12 cm
volume = π × 5² × 12
volume = π × 25 × 12
volume = 300π
Volume of a cone:volume = 1 / 3 πr²h
r = 10 cm
h = ?
300π = 1 / 3 × π × 10² × h
300π = 100πh / 3
900π = 100πh
h = 900π / 100π
h = 9 cm

one aquarium has a length of 7/2 feet, a width of 4/3 feet, and a height of 3/2 feet. what is the volume of the aquarium?
The required volume of the given aquarium is given as 7 cubic feet.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
here,
The volume of an aquarium can be found by multiplying its length, width, and height.
Given the length of the aquarium as 7/2 feet, the width as 4/3 feet, and the height as 3/2 feet, the volume can be calculated as:
Volume = 7/2 × 4/3 × 3/2
= 7 cubic feet
