The graph below have a same shape what is the equation of the red graph?
A) g(x)=(3-x)2
B) g(x)=3-x2
C) g(x)=2-x2
D) g(x)=(2-x)2
Answers
============================================================
Explanation:
The y intercept of the blue curve f(x) is (0,5)
The y intercept of the red curve g(x) is (0,2)
We see that the y intercept has been shifted down 3 units when going from f(x) to g(x). Overall, the entire f(x) curve has been shifted down 3 units to get the g(x) curve.
Based on that, we would say
g(x) = f(x) - 3
g(x) = (5-x^2) - 3
g(x) = -x^2 + (5 - 3)
g(x) = -x^2 + 2
g(x) = 2 - x^2 ..... answer is choice C
Answer:
2-x^2

express 0.484848..... in p/q form
Answers
It's in p/q form where p = 16 and q = 33.
=======================================================
Work Shown:
x = 0.484848.....
100x = 48.4848.....
I multiplied both sides by 100 to move the decimal over 2 spots. Both decimal values for x and 100x have an infinite string of "48"s repeated after the decimal point. When we subtract, those infinite strings will cancel out
100x - x = 99x
48.4848..... - 0.484848..... = 48
So after subtracting straight down, we have the new equation 99x = 48 which solves to x = 48/99
Divide both parts by the GCF 3 to fully reduce
48/3 = 16
99/3 = 33
Therefore, x = 48/99 = 16/33 = 0.484848...
I recommend using a calculator to confirm that 16/33 = 0.484848...
Side note: your calculator may round the last digit, but this is of course rounding error

Zagia is taking a bicycling trip across the United States. Her destination is 3, 150
miles away. If Zagia travels 90 miles per day, how far does she have left to travel
after 20 days of bicycling?
The distance left after 20 days is
miles.
Answers
Answer: The distance left after 20 days is 1350 miles
Step-by-step explanation:
To calculate the distance, we use the formula:
[tex]s=\frac{d}{t}[/tex]
where,
s = speed of the bicycle = 90 miles/day
t = time taken = 20 days
d = distance travelled = ? miles
Putting values in above equation, we get:
[tex]d=(90miles/day\times 20days)=1800 miles[/tex]
Total distance to the destination = 3150 miles
Distance travalled in 20 days = 1800 miles
Distance left after 20 days = [3150 - 1800] = 1350 miles
Hence, the distance left after 20 days is 1350 miles

Calculate the number of vertices in a full 5-ary tree with 35 internal vertices.
Also, find out the number of leaves
Answers
Answer:
Step-by-step explanation:
With 35 internal nodes, there are 5*35=175 vertices out of which are 175-35=140 leaves.
The number of vertices in a full 5-ary tree is 175.
The number of leaves is 140.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of full trees = 5
Number of internal vertices = 35
Now,
The number of vertices.
= 5 x 35
= 175
Now,
The number of leaves.
= 175 - 35
= 140
Thus,
Number of vertices is 175.
Number of leaves is 140.

Jimmy wants to draw a 50° angle. Fill in the missing step to make sure his drawing is completed in the correct order:
Step 1: He draws a ray.
Step 2: He lines up his protractor with the baseline on the ray and the origin of the protractor on the vertex.
Step 3: ________
Step 4: He uses the bottom of the protractor to draw a straight line connecting the mark he made with the vertex.
Step 5: He draws arrows on both ends to make them rays.
Anwsers:
1. He lines up his ruler with the ray and the zero on the ruler.
2. He finds 50° on the protractor and draws a mark on the paper.
3. He lines up his protractor with a straight line and draws a mark on the paper.
4. He draws parallel lines.
Answers
Answer:
2. He finds 50° on the protractor and draws a mark on the paper.
Step-by-step explanation:
Construction is a topic that requires a step wise procedure during the process. In the given question, since Jimmy wish to draw an angle of 50°, he should locate the angle on his protractor and draw a mark on the paper. This is with respect to the previous steps observed.
The essence of the protractor is for Jimmy to accurately measure the angle. Thus he has to determine the angle by the use of a protractor before the construction can be complete.
Therefore the required procedure in step 3 is he finds 50° on the protractor and draws a mark on the paper.
Answer He finds 50° on the protractor and draws a mark on the paper.

Find the measure of angle X. The horizontal lines are parallel. HINT: The sum
of all interior angles in a triangle is 180 degrees.
Answers
===========================================================
Explanation:
The angle adjacent and supplementary to the 107 degree angle is 73 degrees because 107+73 = 180.
Or you could say 180 - 107 = 73.
The base angles of the upper isosceles triangle are 73 degrees each, which means the third remaining angle (let's call it y for now) is
73+73+y = 180
146+y = 180
y = 180-146
y = 34
Refer to the diagram below. Notice how the 34 degree angle shows up twice because we have vertical angles. Consequently, the base angles of the bottom isosceles triangle are y = 34 degrees each
We can now solve for x
y+y+x = 180
34+34+x = 180
68+x = 180
x = 180-68
x = 112, so the answer is choice D
