Choose the function whose graph is given by:
Answer:
A. y = 3sin(x-2) + 1
Step-by-step explanation:
The function whose graph is y= 3 sin (x-2)+1.
What is Function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
As, From the graph that is provided to us we observe that,
when x=2 then f(x)=1.
1. y= 3 sin (x-2)+1
When x=2 gives y= 1
So, the equation satisfied.
2. y = 3 sin (x-2)+2
When x= 2 gives y= 2
So, the equation not satisfied.
3. y = 3 cos (x-2)+1
When x= 2 gives y > 1
So, the equation not satisfied.
Thus, the required function is y= 3 sin (x-2)+1.

An airplane's change in altitude before landing is shown in the table. What equation
represents this change in altitude?
Answer:
Step-by-step explanation:
We have been given a table that represents the altitude of an airplane with passing minutes.
Since we know that equation of a line in slope-intercept form is: y=mx+b, where, m = Slope of the line and b = y-intercept.
To find the equation of line we will have to the slope of our given line using values from table.
m=\frac{y_2-y_1}{x_2-x_1}, where,
y_2-y_1 = Change in two y-coordinates.
x_2-x_1 = Change in the corresponding x-coordinates.
Upon substituting the coordinates of point (1, 35000) and (2, 31000) we will get our slope as:
m=\frac{31000-35000}{2-1}
m=\frac{-4000}{1}=-4000
Now let us find y-intercept of our given line by substituting m=-4000 and the coordinates of point (1, 35000) in slope intercept form of equation.
31000=-4000*1+b
31000=-4000+b
31000+4000=-4000+4000+b
35000=b
Upon substituting the value of slope and y-intercept the equation of line will be:
a=-4000m+35,000
Therefore, the equation representing the change in altitude a after m minutes is a=-4000m+35,000 and option A is the correct choice.
Twenty-four 4-inch wide square posts are evenly spaced with 5 feet between adjacent posts to enclose a square field, as shown. What is the outer perimeter, in feet, of the fence? Express your answer as a mixed number.
Answer:
129 1/3
Step-by-step explanation:
According to Alcumus, "There are 20 square posts which are not on a corner, so there are $20/4=5$ square posts on each side, not including the corner posts. Including the corner posts, there are 7 posts on a side, which means that there are 6 five-foot gaps between posts. Altogether the length of a side is $7\left(\frac{1}{3}\right)+6(5)=32\frac{1}{3}$ feet. The perimeter of the square is four times the side length, so the perimeter is $4\cdot 32\frac{1}{3}=\boxed{129\frac{1}{3}}$ feet."
The outer perimeter is 129 1/3 feet.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Twenty-four 4-inch wide square posts are evenly spaced with 5 feet.
So, there are $20/4
=5$ square posts on each side, not including the corner posts.
and, including the corner posts, there are 7 posts on a side, which means that there are 6 five-foot gaps between posts.
Then, the length of a side is
= 7 1/3 + 6(5)
= 32 1/3 feet
and, The perimeter of the square
= 4 x 32 1/3
= 129 1/3 feet

What is the area of the lawn in square meters?
F 108 m2
G 60 m2
H 72 m2
J 120 m2
Answer:
G) 60 m2
Step-by-step explanation:
1) Cut off the triangles and solve for the area of the rectangle.
12 m x 4 m = 48m
2) Now that we have the big area of the rectangle, we just have to solve for the 2 triangles on the ends. Of the 18 m at the top, we uses 12 m to make the rectangle. That means there are 6 m that was not incorporated in the rectangle. Since there are 2 triangles, we can conclude that the base of each triangle is 3. Now we just have to use the equation for a triangle to find the area.
4 m x 3 m x 1/2 = 6m (each triangle = 6m)
3) Add up all of the values to get the complete area
48m + 6m + 6m = 60 m2

Answer:
212.5 cm² and 120 in²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
(4)
Here b = 25 and h = 17, thus
A = 0.5 × 25 × 17 = 212.5 cm²
(5)
Here b = 12 and h = 20, thus
A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

A.
(0,-2)
B.
(2,0)
C.
(0,2)
D.
(-2,0)
Answer:
The y-intercept of function g located at (0,2)
Step-by-step explanation:
Function :[tex]g(x)=x^2+2[/tex]
g(x) is a transformation of the quadratic parent function
We are supposed to find the where is the y-intercept of function g located
y intercept = the y-coordinate of a point where a line, curve, or surface intersects the y-axis i.e. x =0
So, substitute x = 0 in function
g(x)=x^2+2
g(0)=0^2+2
g(0)=2
So,(x,y)=(0,2)
So, The y-intercept of function g located at (0,2)

Two interior angles of a triangle each measure 34°. What is the measure of the third interior angle?
A. 146°
B. 292°
C. 56°
D. 112°
Answer:
D. 112
Step-by-step explanation:
Since we know that a triangle totals 180 degrees, we can easily figure out the third angle. Since each measure 34 degrees, simply multiply by 2. You get 68 degrees. Then you do 180-68 to get 112.
Naomi used 100 tiles to create a design. Blue tiles make up 1/2 of the design. Another 15 tiles are green, and 1/5 of the tiles are yellow. The rest of the tiles are red. How many red tiles did Naomi use in her design?
A. 15 tiles
B. 25 tiles
C. 65 tiles
D. 85 tiles
Answer:
Naomi used 15 red tiles in her design.
Step-by-step explanation:
We need to add the total number of tiles that we know to find out the unknown value of red tiles. The blue tiles make up 1/2 of the design, or 50 tiles. Next we will add the green tiles, which Naomi used 15 of, as stated.
So far, we have figured out how many blue and green tiles we have. (50 blue, and 15 green, which is a total of 65).
Now we need to calculate the number of yellow tiles, which equal 1/5 of the design. 1/5 of 100 is 20.
Now we add all of our tiles that we already know. We have 50 red + 15 green + 20 yellow which = 85.
Now to find the unknown value of red tiles, we subtract our 85 other tiles from the 100 total tiles, and the ends us up with 15 red tiles.

The four friends purchased two same-sized pitchers of
soda for dinner.
• Jaxson drank 2/5 of a pitcher of soda.
• Kesha drank 0.4 of a pitcher of soda.
• Luann drank 1/2 of a pitcher of soda.
• Samuel drank the rest of the soda.
How much soda did Samuel drink?
Answer:
4/10 of a pitcher
Step-by-step explanation:
Jaxon drank 2/5 = 0.2 = 4/10
Kesha drank 0.4 = 4/10
Luann drank 1/2 = 5/10
4/10 + 4/10 + 5/10 = 13/10 = 26/30
Which would leave Samuel to drink the remaining 4/10 of the soda.

Juanito looked out the window and saw 20 bicycles and skateboards. There were a total 52 wheels. How many of each did he see , steps ?
Answer:
Let's denote:
x: number of bicycles
y: number of skateboards
Then, we have:
x + y = 20
2x + 4y = 52
=> 2(20 - y) + 4y = 52
=> 2y = 12
=> y = 6 (number of skateboards)
=> x = 14(number of bicycles)

The scale factor for this dilation is 2
What is dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image.
As per the given data:
We are given a diagram having 2 triangles, we need to find the scale factor for this dilation.
For finding the scale factor, we can find the ratio of the corresponding sides of the two triangles.
Scale factor for ΔG'H'I' and ΔGHI :
= [tex]\frac{H'I'}{HI}[/tex]
From the given graph, we can clearly observe that
H'I' = 8 + 4 = 12
HI = 4 + 2 = 6
[tex]\frac{H'I'}{HI}[/tex] = [tex]\frac{12}{6}[/tex] = 2
Hence, The scale factor for this dilation is 2.
