Which expression represents a rational number?
Please help right now!!!
Answer:
A
Step-by-step explanation:
Every integer is a rational number; a whole number. The square root of 49 equals 7, which is the only outcome giving an integer as an answer.
Asif and Ben share $2100 in the ratio Asif: Ben = 3:7.
Work out how much Asif receives.
$2100
Answer:
$630 for Asif
Step-by-step explanation:
Asif gets 3/10ths
So
2100 x 3/10 = $630 for Asif
Which statement describes the sequence defined by a Subscript n Baseline = StartFraction n squared minus 16 Over n cubed + 4 EndFraction? The sequence diverges. The sequence converges to 0. The sequence converges to 1. The sequence converges to ∞.
Calculating the limit as n goes to infinity, it is found that:
The sequence converges to 0.
------------------------------
The sequence is given by:
[tex]a_n = \sum_{n=0}^{\infty} f(n)[/tex]
In which
[tex]f(n) = \frac{n^2 - 16}{n^3 + 4}[/tex]
------------------------------
If the limit of f(n) as n goes to infinity is a value, it converges to this value.If the limit of f(n) as n goes to infinity is infinity, it diverges.------------------------------
The limit is:
[tex]\lim_{n \rightarrow \infty} f(n) = \lim_{n \rightarrow \infty} \frac{n^2 - 16}{n^3 + 4}[/tex]
Since it is a limit going to infinity, we consider just the terms with the highest exponents in the numerator and the denominator. Thus:
[tex]\lim_{n \rightarrow \infty} \frac{n^2 - 16}{n^3 + 4} = \lim_{n \rightarrow \infty} \frac{n^2}{n^3} = \lim_{n \rightarrow \infty} \frac{1}{n} = \frac{1}{\infty} = 0[/tex]
Thus: The sequence converges to 0.

During a trip, a driver travelled a distance of 80km at an average speed of 60km/hr.He then changed his speed and travelled the remaining 20km of his journey at 30km/hr. What was the drivers average speed for the entire journey?
Show all working!!
Answer:
50 km/hr
Step-by-step explanation:
D = RT
Time for first part of trip = 80/60 = 4/3 hr.
Time for second part of trip = 20/30 = 2/3 hr.
total time for entire trip = 4/3 + 2/3 = 6/3 = 2 hr.
Total distance = 100 km
Average rate of speed for entire trip = 100/2 = 50 km/hr

If the discriminant of an equation is 10, then the roots are
A) real, rational, and unequal
B) real, irrational, and unequal
C) real, rational, and equal
D) imaginary
Answer:
b
Step-by-step explanation:
Since the given discriminant is 10, hence the roots will be real, irrational, and unequal
Discriminant of an equation
The discriminant is used to determine the nature of the roots of a quadratic equation. The formula for finding the discriminant is expressed as:
D = b^2 - 4ac
If D > 0, the nature of the roots are real, irrational, and unequal If D < 0, the nature of the roots are imaginarySince the given discriminant is 10, hence the roots will be real, irrational, and unequal

Find the area of the wrestling mat.
Answer:
804.25
Step-by-step explanation:
The area of a circle = pi(r)^2
Given the diameter, we can find the radius by dividing the diameter in half.
r=16
pi(16)^2 = 804.25
Answer:
803.84 OR 256 pi
Step-by-step explanation:
Ok!
Step 1:
The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)
R is radius. Remember, radius is half the diameter.
32/2=16.
Step 2:
Do 16^2.
You should get 256.
Step 3:
Multiply 256 by Pi. Pi is 3.14. You should get 803.84.
Step 4:
803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!

I HAVE A MATH TEST PLZ HELP I'M GIVING OUT 50 POINTS PLZ
S.O.S I HAVE MATH
Answer:
Graph included as picture
Step-by-step explanation:
To solve this, plot the given points on the graph
Draw a line through them.
Now select two of those values and we'll find the rate of change.
We'll be using (1,-1) and (3,3)
To find rate of change we will be using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]y_{2} = 3\\y_{1} =-1\\x_{2} = 3\\x_{1} = 1[/tex]
[tex]\frac{3-(-1)}{3-1} = \frac{4}{2} = 2[/tex]
So the rate of change is 2
You will use this rate of change for your other function because they both have the same rate of change
Since we have the rate of change, we can create the slope intercept form formula: y = mx +b
Just substitute for the variables we know
m = rate of change/slope = 2
b = y-intercept = -3
y = 2x + -3
[If you connected all the points in your graph, that's how you found the y-intercept]
Now we have to create the formula for the second function.
We know it will have that same slope of 2
so we have y = 2x + b
To solve for b we can plug in the values we do have which would be (x,y) of (3,6)
6 = 2(3) + b
Now solve
6 = 6 + b
6 (-6) = 6 (-6) + b
0 = b
b = 0
This mean that the y-intercept will be on (0,0)
Plot that point
Now we finish the formula
y = 2x + 0
Connect the dots, make sure the line continues on both of them past the dots and now you have your graph!
I've included a picture of the graph for your reference. I hope this helps, don't be afraid to reach out with further questions!

Answer:
(-.5,0) and (-1.5,0)
or b= -.5
and b= -1.5
Step-by-step explanation:
First we want one side of the equation to equal 0
we have
4b²+8b+3=0
using the quadratic formula we have
(-b±√(b²-4*a*c))/2a
(-8±√(8²-4*4*3))/2*4
(-8±√(16))/8
(-8±4)/8
now we evaulate when ± is addition
(-8+4)/8
-4/8
-.5
and evaulate once more when the ± is subtraction
(-8-4)/8
-12/8
-1.5
Therefore the two solutions are (-.5,0) and (-1.5,0)
Answer:
Step-by-step explanation:
step one - Move terms to the left side
(4b^2 + 8b + 7 = 4)
(4b^2 + 8b + 7 - 4 = 0)
step dose - Subtract the numbers
(4b^2 + 8b + 3 = 0)
step три - Use the sum-product pattern
(4b^2 + 6b + 2b + 3 = 0)

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the histogram is not attached.
However, the solution to your question is to select the interval with the highest frequency
Take for instance, after getting readings from the histogram, yiu have:
1 - 10: 8
11 - 20: 5
21 - 30: 11
31 - 40: 2
And so on.......
Interval 11 - 20 will represent the required interval because it has the highest frequency.
