write the equation for each translation of the graph of y=| 1/2x-2|+3
One unit up
one unit down
The equation for each translation of the graph of y=| 1/2x-2|+3 is
g(x)=| 1/2x-3/2|+3.
Given that,
[tex]y=| 1/2x-2|+3[/tex]
Translate the above one unit to the left
Replace y with f(x)
[tex]f(x)=| 1/2x-2|+3[/tex]
What is the meaning of translation?A translation is a movement of the graph either horizontally parallel to the -axis or vertically parallel to the -axis.
When an absolute function is translated to the left, the resulting function is,
[tex]g(x)=f(x-h)[/tex]
Because it is been translated 1 unit to the left, h = -1
[tex]g(x)=f(x-(-1))[/tex]
[tex]g(x)=f(x+1)[/tex]
Now we calculate f(x+1)
[tex]f(x+1)=| 1/2(x+1)-2|+3[/tex]
[tex]f(x+1)=| 1/2x+1/2-2|+3\\f(x+1)=| 1/2x+1-4/2|+3\\[/tex]
[tex]f(x+1)=| 1/2x+(-3)/2|+3\\\\f(x+1)=| 1/2x-3/2|+3[/tex]
We have,g(x)=f(x+1)
[tex]g(x)=| 1/2x-3/2|+3[/tex]

First, rewrite 23/25 and9/10 so that they have a common denominator.
Then, use <, =, or > to order 23/25 and 9/10.
Answer:
The lowest common multiple of 10 and 25 is 50, so set that as the denominator.
9/10=45/50 (multiply by 5)
23/25=46/50 (multiply by 2)
46/50 > 45/50 therefore
23/25 > 9/10.

Is anyone able to figure this out, I can't do this
Answer:
C. √2 - 1
Step-by-step explanation:
If we draw a square from the center of the large circle to the center of one of the small circles, we can see that the sides of the square are equal to the radius of the small circle (see attached diagram)
Let r = the radius of the small circle
Using Pythagoras' Theorem [tex]a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
to find the diagonal of the square:
[tex]\implies r^2 + r^2 = c^2[/tex]
[tex]\implies 2r^2 = c^2[/tex]
[tex]\implies c=\sqrt{2r^2}[/tex]
So the diagonal of the square = [tex]\sqrt{2r^2}[/tex]
We are told that the radius of the large circle is 1:
⇒ Diagonal of square + r = 1
[tex]\implies \sqrt{2r^2}+r=1[/tex]
[tex]\implies \sqrt{2r^2}=1-r[/tex]
[tex]\implies 2r^2=(1-r)^2[/tex]
[tex]\implies 2r^2=1-2r+r^2[/tex]
[tex]\implies r^2+2r-1=0[/tex]
Using the quadratic formula to calculate r:
[tex]\implies r=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]\implies r=\dfrac{-2\pm\sqrt{2^2-4(1)(-1)}}{2(1)}[/tex]
[tex]\implies r=\dfrac{-2\pm\sqrt{8}}{2}[/tex]
[tex]\implies r=-1\pm\sqrt{2}[/tex]
As distance is positive, [tex]r=-1+\sqrt{2}=\sqrt{2}-1[/tex] only
To rent a car, company A charges $55 per day and 33 cents per mile. Company B charges no daily fee, but 55 cents per mile. How many miles must you drive for Company B to cost the same as company A?
please show your work
and give the answer
Answer:
about 101 miles to equal the same amount as place A. (if this is daily")
Step-by-step explanation:
so how I went about this is first I added 55+0.33 because thats how much you need to drive one mile for one day with place A. and that equaled 50.30 so then I divided 50.30 by 0.55 because thats all it costs per mile for place B so I got 100.545454545 so i just rounded it up to 101
i hope im right plmn;)
Answer:
no they are not the same tax or rate because 33 cents off is company B
Step-by-step explanation:
88 cents for company A and 55 cents for company B
and company A charged a fee of 33 cents but company B did not

Given the function f(x)=5x+4, find f(x-2)
Answer:
5x - 6
Step-by-step explanation:
f(x) = 5x + 4
f(x-2) = 5(x -2) + 4
f(x-2) = 5x - 10 + 4
f(x-2) = 5x - 6
I hope this helps!
Answer:
5x - 6
Step-by-step explanation:
Plug in x-2 to the function:
f(x - 2) = 5(x - 2) + 4
= 5x - 10 + 4
= 5x - 6

What value of x makes the equation 4x + 5 = 11 true?
Answer:
D
Step-by-step explanation:
If we plug in D, we get 4(3/2) + 5 = 11.
4(3/2) + 5 = 11
12/2 + 5 = 11
6 + 5 = 11
11 = 11
Therefore,the answer is D.

For finding the surface area of the entire cylinder, we need to use the proper formula which is [tex]SA = 2 \pi r h + 2 \pi r^2[/tex]. Since the problem already gives us the radius and height, we can easily plug in the numbers. The equation should now look like this: [tex]SA = 2 * 3.14*3*6 +2*3.14*3^2[/tex].
After multiplying and adding all the numbers in the formula, we get a surface area of 169.56 yards squared.
For the lateral surface area, we can just subtract the [tex]2 \pi r^2[/tex] part from the formula.
[tex]SA = 2 * 3.14* 3 *6[/tex], which is 113.04 yards squared for the lateral surface area.

A basket contains the following pieces of fruit: 3 apples, 4 oranges, 4 bananas, 2 pears, and 3 peaches. Jonas picks a fruit at random and does not replace it. Then Beth picks a fruit at random. What is the probability that Jonas gets an orange and Beth gets a peach?
Answer:
Probability that Jonas gets an orange is 1/4 and Beth gets a peach is 3/16.
Step-by-step explanation:
Here,
The total number of fruits n(S) = 3 + 4 + 4 + 2 + 3
= 16
The total number of oranges n(O) = 4
The total number of peas n(P) = 3
Now,
P(O) = n(O)/n(S)
= 4/16
= 1/4
Again,
P(P)= n(P)/n(S)
= 3/16

Answer:
x = 60°
Step-by-step explanation:
m∠EGD = m∠BGF = x°
The following m∠EGD, m∠DGC, m∠EGA lies on a straight line.
A straight line has total 180° interior angle.solve:
m∠EGD + m∠DGC + m∠EGA = 180°x + 90° + 30° = 180°x + 120° = 180°x = 180° - 120°x = 60°What is the slope of the table.
Answer:
slope is -5
Step-by-step explanation:
The formula for slope is:
m = (y2 - y1)/(x2 - x1)
m = slope
y2 = y-coordinate of second point
y1 = y-coordinate of first point
x2 = x-coordinate of second point
x1 = x-coordinate of first point
We can choose our first and second points as any points on the table, but we will choose the first andd second points which are (-5,10) and (-3,0).
y2 = 0
y1 = 10
x2 = -3
x1 = -5
m = (0-10)/(-3-(-5))
m = (-10)/(-3+5)
m = (-10)/(2)
m = -5

A bakery's specialty flour is a mixture of almond and coconut flour. The ratio of almond flour to coconut flour is 7:38 by volume. If a backery uses 180 cups of the flour mixture in a day, what is the volume, in cups, of the almond flour used?
According to the question,
The ratio of almond flour to coconut flour is 7:38
so,
the volume of the almond flour used in a day ,in terms of cups would be
[tex] \rightarrow \frac{180 \times 7 }{7 + 38} \\ [/tex]
[tex] \rightarrow \frac{1,260 }{45} \\ [/tex]
[tex] \rightarrow28[/tex]
hence ,28 cups of almond flour would be required to meet the need to prepare the mixture for a day.
______________________________________
volume of coconut flour required in a day ,in terms of no. of cups would be
[tex] \rightarrow \frac{180 \times 38 }{7 + 38} \\ [/tex]

[tex] \rightarrow152[/tex]
hence ,152 cups of coconut flour are required to make the mixture.
_______________________________________
verification↷Given that,
The ratio of almond flour to coconut flour is 7:38
7:38 = 28:152
7:38 = 7 :38
