Answer:
The new function is g(x) = x² +1
Step-by-step explanation:
Explanation:-
Given that the function f(x) = x²
From graph ,
The parabola y = x² is shifting to up with '1' units
y = x² +1
The new function is g(x) = x² +1
Verification:-
y = x²+1
Put x=0 ⇒ y =1
The point (0,1) lies on the parabola y = x²+1
similarly put x =1 and y = 2
The Point (1,2) lies on the Parabola y = x²+1
∴ The new graph y = x²+1

Find the volume of each figure. Round your answers to the nearest hundredth, if necessary. Leave your answers in terms of pi for
answers that contain pi.
Answer:
125π km³
Step-by-step explanation:
We are to find the Volume of a cylinder
From the question:
Height of the cylinder = 5km
Radius of the cylinder = 5 km
The volume of a cylinder =
πr² h
Hence:
π × 5² × 5
= 125π km³
The volume of the cylinder = 125π km³
Option d is the correct option
Which expression is equivalent to the given expression?
4(a−3)
A.-8a
B.4a-12
C.4a-3
D.-4(a+3)
Answer:
B. 4a-12
Step-by-step explanation:
First, we can simplify the equation. We use distributive property to remove the 4 and parenthesis.
4a - 12
This is the furthest we can go, meaning the answer is B.

A retail shop is replacing their flooring with new tile. New tile will go in the point shaded area below. Determine the total square feet of tile needed to complete the job.
Answer:
137 ft²
Step-by-step explanation:
The shop is rectangular in shape. The area of a rectangle is given by:
Area = length * width
Since the length of the shop = 20 ft and the width = 10 ft, therefore:
Area of the shop = length * width = 20 ft * 10 ft = 200 ft²
The part that would not be tiled is of triangular shape. The area of a triangle is given as:
Area = (1/2) * base * height
The base of the triangle = 18 ft, the height = 7 ft. Hence:
Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²
The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part
The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²
The following three shapes are based only on squares, semicircles, and quarter circles. find the perimeter and the area of each shaded part. give your answer as a completely simplified exact value in terms of π (no approximations).
I need this answer really fast. As soon as possible.
Step-by-step explanation:
Area of Shaded part
= 2 * Area of Quarter-circle - Area of Square
= 0.5π(8)² - 8²
= 32(π - 2)cm².
Perimeter of Shaded part
= 0.5 * 2π(8)
= 8πcm.
The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively
Perimeter and area of a circleRadius, r = 8 cm
Perimeter of a circle = 2πrPerimeter of s quarter circle = 2πr/4= 1/2πr
Perimeter of Shaded part = 1/2 * 2πr
= 1/2 × 2 × π × 8
= 8πcm.
Area of a circle = 2πr²Area of quarter circle = 2πr²/4= 1/2πr²
Area of a square = length ²Area of Shaded part
= Area of Quarter-circle - Area of Square
= 0.5π(8)² - 8²

y is inversely proportional to 7I+x.
When x = 8, y = 2.
Find y when x= 15.
I am taking 7I+x to mean 71+ x.
Answer: y=1.837
Step-by-step explanation:
Step 1
Let y is inversely proportional to 7I+x be mathematically be written as
y ∝ 1/7I+x
Introducing our proportionality of constant , K we have that
y ∝ 1/7I+x
y =K 1/7I+x
y= K/ 7I+xh
Step 2
so when x= 8, and y =2, k becomes
y= K/ 7I+x
k= y x (7I+x)
=2 x (71 + 8)
2x 79
=158
when x= 15, y =?
y= K/ 7I+x
y= 158/ 71 + 15
y=158/86
y=1.837
What is the measure of angle b?
A.
36°
B.
56°
C.
63°
D.
117°
Answer:
A. 36*
Step-by-step explanation:
first find angle a:
180-117=63
a=63
then find angle b by subtracting 81 and 63 from 180
180-81=99
99-63=36
angle b = 36

A walking track is 2 1/2 miles long. How many feet is that?
Answer:
13,200 feet
Step-by-step explanation:
Answer:
13,200 feet
Step-by-step explanation:
In one mile, there are 5,280 feet.
You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.
X = the number of feet in 2.5 miles.
[tex]\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}[/tex]
To find X, all you need to do is cross multiply.
So,
X = 5280 × 2.5 = 13,200 feet

Law of Cosines: c2 = a2 + b2 - 2ab cos C
Answer:
x = 118 degrees approximately
Step-by-step explanation:
Here, we want to get the measure of the angle marked x
We shall use the side facing it and apply the cosine rule
The side facing the angle measures 90
Thus, we have it that;
90^2 = 55^2 + 50^2 - 2(50)(55) cos X
2575 = - -5,500 cos X
X = cos^-1(-2575/5,500)
X = 118 degrees approximately

Last week, an online site received $355.60 for selling 20 cell phone accessories Cell phone cases sell for $10.98 and Airpods sell for $27.98.
1. Define the variables.
2. Then, write the system of equations to model this situation.
Answer:
i. Cell phone cases
Airpods
ii. x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
iii. x = 12, and y = 8
Step-by-step explanation:
Amount of sale = $355.60
Cost of Cell phone cases = $10.98
Cost of Airpods = $27.98
Number of phone accessories sold = 20
1. The variables to be considered in the question are:
i. Cell phone cases
ii. Airpods
2. Let the number of cell phone cases bought be represented by x, and that of airpods be represented by y.
Thus,
x + y = 20 .............. 1
10.98x + 27.98y = 355.60 .............. 2
From equation 1,
x = 20 -y
substitute the value of x in equation 2
10.98(20 - y) + 27.98y = 355.60
219.6 -10.98y + 27.98y = 355.60
17y = 136.60
y = [tex]\frac{136.60}{17}[/tex]
y = 8.0353
So that,
x = 20 -y
= 20 - 8.0353
x = 11.9647
Thus,
x = 12, and y = 8
