f(x) = x^2 . What is g(x)?
Answer:
g(x) = (1/4x)^2
Step-by-step explanation:
Given f(x), we want to get g(x)
As we can see, the point (4,1) lies on the graph of g(x)
So the correct option will be the one where g(4) = 1
Let us take a look at the second option
g(x) = (1/4x)^2
Here,
g(4) = (1/4 * 4)^1 = 1^1 = 1

Town Q and Town P were 119 km apart. Van drove from
Town Q to Town P at an average speed of 70 km/h. How
much sooner would he have arrived at Town P if he had
travelled at an average speed of 85 km/h instead?
min
Answer:
18 minutes earlier
Step-by-step explanation:
Given
[tex]Distance =119km[/tex]
[tex]Speed\ 1 = 70km/h[/tex]
[tex]Speed\ 2 = 85km/h[/tex]
Required
Determine how much sooner if traveled at speed 2 instead of speed 1
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{Distance}{Speed }[/tex]
For Speed 1
[tex]Time= \frac{119km}{70km/h}[/tex]
[tex]Time= 1.7hr[/tex]
For Speed 2
[tex]Time= \frac{119km}{85km/h}[/tex]
[tex]Time= 1.4hr[/tex]
Calculate the difference
[tex]Difference = 1.7hr - 1.4hr[/tex]
[tex]Difference = 0.3hr[/tex]
Convert to minutes
[tex]Difference = 0.3*60\ min[/tex]
[tex]Difference = 18\ min[/tex]
If traveled at 85km/h, the van will arrive 18 minutes earlier

The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 23cm and a second side that is 4cm less than twice the third side, what are the possible lengths for the second and third sides?
Answer:
21 < x < 27
Step-by-step explanation:
Given that :
Side 1 = 23
Side 3 = x
Side 2 = 2x - 4
23 + x > 2x - 4
Collect like terms
x - 2x > - 4-23
-x > - 27
x < 27
Also ;
23 + 2x - 4 > x
23 - 4 > x - 2x
21 > - x
-21 < x
x > - 21
Hence,
Possible values of x :
x > 21 and x < 27
21 < x < 27
Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed of 2 miles per hour. Brian is hiking downhill at a speed of 4 miles per hour. How long will it take for the two to meet?
Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours

A jar has marbles in it. Three tenths of the marbles are red. Five tenths of the marbles are blue.
Two tenths of the marbles are green. Which of these fractions is equivalent to four eighths?
The red marbles are 3/10 of the total.
The blue ones are 5/10 of the total.
The green ones are 2/10 of the total.
Of these, 5/10=1/2=(1×4)/(2×4)=4/8
Therefore, five tenths is equivalent to four eighths.

Find the value of x in the rectangle ABCD.
Answer:
52°
Step-by-step explanation:
here's your solution
=> we know that the measure of angle of rectangle is 90°
=> 38° + X = 90°
=> X = 90° - 38°
=> X = 52°
hope it helps
Answer:
52 because D is a right angle,so 90 - 38 will give you 32
another interesting thing that can help you in math, the opposite sides if a quad are always equal, in this case D and B is equal,and C and A is equal.If you add C and a it will give you 180 degrees and if you add d and b it will give you 180 degrees
so 180 + 180

Andy is wrapping gifts for the holidays. He has 3 rolls of wrapping paper that are 18- inches wide and 24- inches long. What is the total area that 3 rolls of wrapping paper could cover?
Answer:
1296 sq inches
Step-by-step explanation:
To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.

Step-by-step explanation:
The 1st 3 terms of an A.P., a, a+d, and a+2d, are the same as the 1st 3 terms of a G.P.( a is not equal to 0). Show that this is only possible if r=1 and d=0
Answer:
See Below.
Step-by-step explanation:
The first three terms of an A.P is equivalent to the first three terms of a G.P.
We want to show that this is only possible if r = 1 and d = 0.
If a is the initial term and d is the common difference, the A.P. will be:
[tex]a, a+d, \text{ and } a+2d[/tex]
Likewise, for the G.P., if a is the initial term (and it does not equal 0) and r is the common ratio, then our sequence is:
[tex]a, ar,\text{ and } ar^2[/tex]
The second and third terms must be equivalent. Thus:
[tex]a+d=ar\text{ and } a+2d=ar^2[/tex]
We can cancel the d. Multiply the first equation by -2:
[tex]-2a-2d=-2ar[/tex]
We can now add this to the second equation:
[tex](a+2d)+(-2a-2d)=(ar^2)+(-2ar)[/tex]
Simplify:
[tex]-a=ar^2-2ar[/tex]
Now, we can divide both sides by a (we can do this since a is not 0):
[tex]-1=r^2-2r[/tex]
So:
[tex]r^2-2r+1=0[/tex]
Factor:
[tex](r-1)^2=0[/tex]
Thus:
[tex]r=1[/tex]
The first equation tells us that:
[tex]a+d=ar[/tex]
Therefore:
[tex]a+d=a(1)\Rightarrow a+d=a[/tex]
Hence:
[tex]d=0[/tex]

Percentage (P) = [Final value - Initial value] / Initial value x 100
Diane makes fruit punch with 3 cups of cranberry juice, 2 cups of mandarin orange juice, and 3 cups of watermelon juice.
The percentage of the punch in cranberry juice will be given as,
P = [3 / (3 + 3 + 2)] x 100
