Given:
The parent sine function is [tex]f(x)=x^2[/tex].
It shifts three units to the left and four units down.
To find:
The new function.
Solution:
The translation is defined as
[tex]f_1(x)=f(x+a)+b[/tex] .... (1)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
Graph shifts 3 units to the left. So, a=3.
Graph shifts 4 units down. So, b=-4.
Putting a=3 and b=-4, we get
[tex]f_1(x)=f(x+3)-4[/tex]
[tex]f_1(x)=(x+3)^2-4[/tex] [tex][\because f(x)=x^2][/tex]
Here, new function is also defined by f(x). So, [tex]f(x)=(x+3)^2-4[/tex].
Therefore, the correct option is d.

Determine the DOMAIN and RANGE from the graph
Given:
The graph of a function.
To find:
The domain and range of the function.
Solution:
We have, the graph of a function and we need to find the domain and range of the function.
We know that, domain is the set of input values (x-values) and range is the set of output values (y-values).
From the given graph it is clear that function is defined for all values of x except x=0 because as x tends to 0 the function tends to negative or positive infinite. So, domain can be any real number except 0.
[tex]Domain=R-\{0\}[/tex]
[tex]Domain=(-\infty,0)\cup (0,\infty)[/tex]
From the given graph it is clear that the value of function can be any real number except y=0. So, range can be any real number except 0.
[tex]Range=R-\{0\}[/tex]
[tex]Range=(-\infty,0)\cup (0,\infty)[/tex]
Therefore, the correct option is B.

Carl is boarding a plane. He has 222 checked bags of equal weight and a backpack that weighs 4 Write an equation to determine the weight, w of each of Carl's checked bags
Answer: 2w + 4 = 35
Step-by-step explanation:
Carl's two checked bags and his one backpack together weigh 35kg.
Carl's two checked bags have equal weight so both their weight can be denoted as 2w.
Equation is;
2w + 4 = 35
If you were to solve;
2w + 4 = 35
2w = 35 - 4
w = 31/2
w = 15.5kg
The two boxes shown are cuboids.
Work out how many of the smaller boxes you would need to completely fill the larger one.
Answer:
250 smaller cuboids
Step-by-step explanation:
Given
Small and Big cuboids
Required
Number of smaller cuboids in the big one
To do this, we calculate the volume of both cuboids.
[tex]Volume = Length * Width * Height[/tex]
For the small cuboid
[tex]V_1 = 10cm * 3cm * 4cm[/tex]
[tex]V_1 = 120cm^3[/tex]
For the big cuboid
[tex]V_2 = 50cm * 30cm * 20cm[/tex]
[tex]V_2 = 30000cm^3[/tex]
The number of small in big is then calculated by diving the volumes
[tex]Number = \frac{V_2}{V_1}[/tex]
[tex]Number = \frac{30000cm^3}{120cm^3}[/tex]
[tex]Number = \frac{30000}{120}[/tex]
[tex]Number = 250[/tex]
Hence, there are 250 small cuboids in the large one

PLEASE HELPPP I REALLY NEED IT I DONT UNDERSTAND PART C PLEASE SOMEONE EXPLAIN TO ME AND I WILL GIVE BRAINLEST THANK YOU SM!!!! PLEASE I REALLY DONT UNDERSTAND
Answer:
Step-by-step explanation:
12 miles is the ride distance
the guy is able to travel at 6 yard per second
Question C asks how many minutes will the trip take
first we have to convert miles to yards....
there are 1760 yards in one mile
12*1760= the total distance to be traveled.. in yards..
21,120 yards
Next we'll figure out the time to travel that distance.. but we're give a rate of travel in seconds... 6 yards every second
so divide the total yards by the seconds.. that are take to travel every second.. in on second he goes 6 yards. so divide the total yards by 6 for each second of travel
21,120 / 6 = 3520 seconds to go 12 miles or the 21,120 yards.. it's the same distance in different units
then.. b/c the question is asking for minutes divide the 3,520 seconds by 60.. b/c that's how many seconds are in one minute
3,520 / 60 = 58.6666666666666 minutes or 58 minutes and 2/3 of one minute.... make sense?

20. Carpenters use the term pitch to describe the slope of a
roof. For example, a roof with a pitch of 1/4
means the
roof has 1 foot of vertical rise for every 4 feet of
horizontal distance. The figure below shows a 13-foot-
long roof with 5 feet of vertical rise and x feet of
horizontal distance. What is the pitch of this roof?
F. 1/6
G. 58
H. 5/12
J. 5/14
K. 5/18
Answer:
5/12
Step-by-step explanation:
The pitch of the roof is 5/12.
Option H is the correct answer.
What is the Pythagorean theorem?Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We can apply this theorem only in a right triangle.
Example:
The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.
Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm
We have,
We know that the pitch of a roof is defined as the ratio of the vertical rise to the horizontal distance, and is typically expressed as a fraction.
In this case, we are given that the roof is 13 feet long, with 5 feet of vertical rise and x feet of horizontal distance.
Therefore,
The pitch of the roof.
Pitch = vertical rise / horizontal distance
Pitch = 5 / x
We don't know the value of x, but we can use the fact that the roof is 13 feet long to solve it.
Since the horizontal distance and vertical rise form the legs of a right triangle, we can use the Pythagorean theorem to find the value of x.
x² + 5² = 13²
x² + 25 = 169
x² = 144
x = 12
Now,
Pitch = 5 / x
= 5 / 12
Therefore,
The pitch of the roof is 5/12.

98. What is the sum of the first 27 terms in the arithmetic series 25 +19+13 + ...?
Answer:
sum of the first 27 terms = -1431
Step-by-step explanation:
arithmetic series sum of the first n terms formula:[tex] s_{n} = \frac{n}{2} (2a + (n - 1)d)[/tex]
n = 27 terms
first term, a = 25
common difference, d = 19 - 25 = -6
substitute the values into the formula
[tex] s_{27} = \frac{27}{2} (2(25) + (27 - 1)( - 6))[/tex]

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50 degree angle of elevation. His eyes are 5 feet above the ground. Using cos 50= .64, what is the height of the tree to the nearest foot?
Answer:
23.84 feet
Step-by-step explanation:
Solving this question above, we using Trigonometric function tangent = Opposite/Adjacent
Opposite side + h = Height of the tree
We are told that:
A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50 degree angle of elevation. His eyes are 5 feet above the ground.
20 feet = Adjacent side = Distance form the tree
tan 50 = (h+5)/20
Cross Multiply
h + 5 = 20 × tan50
h = 20tan50 - 5
h= 18.835071852
h =18.84
Therefore the height of the tree is calculated as:
18.84+5 feet
=23.84 feet

Joan kicked a soccer ball. The height of the ball, h, in metres, can be modelled by h =-1.2x^2 + 6x , where x is the horizontal distance, in metres, from where she kicked the ball.
Answer:
7.5m
Step-by-step explanation:
Since we are not asked what to look for we can find the maximum height reached by the ball
The ball reaches its maximum height when dh/dx = 0
dh/dx = -2.4x + 6
0 = -2.4x + 6
2.4x = 6
x = 6/2.4
x = 2.5
Get the max height
Recall:
h =-1.2x^2 + 6x ,
h(2.5) = -1.2(2.5)^2 + 6(2.5)
h(2.5) = -1.2(6.25)+15
h(2.5) = -7.5 + 15
h = 7.5
Hence the maximum height reached by the ball is 7.5m

The number is 48.
Cost of lawn tractor is $140.
Cost of TV without remote is $387.
Let [tex]x[/tex] be the number
[tex]2(x+(-38))=20\\\Rightarrow x-38=\dfrac{20}{2}\\\Rightarrow x=10+38\\\Rightarrow x=48[/tex]
The number is 48.
[tex]x[/tex] = Cost of lawn tractor
[tex]y[/tex] = Cost of accessories
Cost of lawn tractor is twice of the accessories
[tex]x=2y[/tex]
Total cost of lawn tractor and accessories is $210

[tex]x-y=125[/tex]

It is a triangle
Step-by-step explanation:
This is called Triangle Inequality. We can use its theorem to identify whether these three sides work or not. The Theorem states, "the sum of the smallest lengths of any two sides must be greater than or equal to the length of the remaining side." If we look at the sides, 11,4,7, we can conclude that these are applicable sides for a triangle because the sum of the two smallest lengths, 4 and 7, are the same value as 11. Therefore, these measurements are a triangle.

Third choice, 3/20
Step-by-step explanation:
Add all the numbers on the right side of the chart together:
16 + 12 + 22 + 15 + 26 + 9 = 100
So they're rolled the dice 100 times, and of that, they got a 4 fifteen times. So it's 15/100, simplify that equation and it's 3/20
Simplifying an equation means making an equation have smaller numbers if possible. For this question 15 and 100 can both be divided by 5, it is also the biggest number they can both be divided by, so u divide both by 5 and it's 3 and 20, making it 3/20
