Answer:
B. 5626.9
Step-by-step explanation:
• volume of cylinder= pi(r)2h
• plug in the values into the equation
• pi(8)2(28)
pi=3.14 so 3.14(8)2(28)
• multiply all the values
• you get 5629. 73

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
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.

What is the range of the following parabola? (5 points)
Answer:
D
Step-by-step explanation:
Range is all the possible Y values in a graph
we can see that the graph will never reach a y value greater than three but will go to negative infinity
This means that answer is D (the y value will always be less than or equal to 3)

the equation of the line that is perpendicular to the line with equation y=-2x-1 and passes through the point (1, -2) is?
Answer:
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]
Step-by-step explanation:
Hi there!
Note that:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)1) Determine the slope (m)
When we look at the given line, [tex]y=-2x-1[/tex], we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of [tex]\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (1,-2)
[tex]-2=\frac{1}{2}(1)+b\\-2=\frac{1}{2}+b[/tex]
Subtract 1/2 from both sides
[tex]-2-\frac{1}{2}=\frac{1}{2}+b-\frac{1}{2}\\-\frac{5}{2} = b[/tex]
Therefore, the y-intercept of the line is [tex]-\frac{5}{2}[/tex]. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]

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.

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)

What is the total cost of buying 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts?. The price of nails is $1.30/lb, the price of washers is $0.80/lb, and the price of bolts is $2.50/lb.
Answer: $13.30
Step-by-step explanation:
price of nails = $1.30/lb
price of washers = $0.80/lb
price of bolts = $2.50/lb
The total cost of buying 2 pounds of nails, 4 pounds of washers, and 3 pounds of bolts will be:
= (2 × $1.30) + (4 × $0.80) + (3 × $2.50)
= $2.60 + $3.20 + $7.50
= $13.30
The total cost is $13.30

Given that:
Time Distance

Slope of line, m= Δy/Δx
m= [tex]x_2[/tex]- [tex]x_1[/tex]/ [tex]y_2[/tex]- [tex]y_1[/tex]
m=6-1.5 /200-50
m=4.5 /150
m= 45/1500= 3/100
m=0.03
Hence, slope of line is= 0.03

a whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
Answer:
x = 60
Step-by-step explanation:
The question is asking
$14,700 * (1 - 8%)^x = $100
$14,700 * (1 - 0.08)^x = $100
$14,700 * (0.92)^x = $100
(0.92)^x = $100/$14,700
log(0.92^x) = log($100/$14,700)
x * log(0.92) = log(0.0068027)
x = log(0.0068027)/log(0.92)
x = 59.85
Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.
