Question 8
A log with diameter 60 cm is 3 m in length its hollow centre is 20 cm in diameter.
Find the surface area of the log in cm', including the ends and the inside, correct to one decimal place.
Answer:
The surface area of the log including the ends and the inside is 80424.8 cm²
Step-by-step explanation:
To determine the surface area of the log with hollow center including the ends and the inside, we will find the surface area of the outer part of the log, surface area of the inner part of the log and the surface area of the two ends; and then sum everything up.
From the question,
Diameter of log = 60 cm
Length of log = 3 m = 300 cm
Diameter of hollow center = 20 cm
For the surface area of the outer part,
Area of the outer part = Circumference of the outer part × length
Circumference = 2πr = πd
∴ Area of the outer part = πd × l
(NOTE: d here is the diameter of the log)
d = 60 cm and l = 300 cm
Area of the outer part = 60π × 300 = 18000π cm²
For the surface area of the inner part,
Area of the inner part = Circumference of the inner part × length = πd × l
(NOTE: d here is the diameter of the hollow center)
d = 20 cm and l = 300 cm
Area of the inner part = 20π × 300 = 6000π cm²
For the surface area of one end
This is the difference between the area of the outer end and the area of the inner end
Here, we can determine the area by using
Area = πr², where r is the radius
Radius = Diameter / 2
Radius of outer end (R) = Diameter of log / 2 = 60cm / 2 = 30cm
Radius of inner end (r) = Diameter of hollow center / 2 = 20cm / 2 = 10 cm
∴ Surface area of one end = πR² - πr² = π(R²-r²)
= π (30²-10²)
= π (900 - 100)
= 800π cm²
This is the area of one end
For the two ends,
Area of the two ends = 2 × 800π cm² = 1600π cm²
Hence, the surface area of the log is 18000π cm² + 6000π cm² + 1600π cm²
Surface area of the log = 25600π cm²
Putting the value of π (π = 3.141592654)
Surface area of the log = 25600 × 3.141592654 cm²
Surface area of the log = 80424.77193 cm²
Surface area of the log = 80424.8 cm²
Hence, the surface area of the log including the ends and the inside is 80424.8 cm² (to one decimal place)
In 1-3, match each description with the correct graph. Not all graphs will be used.
1.
My graph is non-proportional with a negative y-intercept.
2.
My graph is proportional with a negative slope.
3.
My graph is non-proportional with a positive slope
Answer:
1. d
2. b
3. a
Step-by-step explanation:
1. d => "my graph is non-proportional with a negative y-intercept."
Rationale: it is non-proportional because it does not pass through the point of origin, (0, 0). And also, the line intercepts the y-axis at a point where the value of y is below the point of origin, 0. That gives us a negative y-intercept value.
2. b => "My graph is proportional with a negative slope."
Rationale: it is proportional because the straight line cuts through the point of origin, (0, 0). And also, the line slants downward from left to the right, thus, such downward slope gives us a negative slope value.
3. a => "My graph is non-proportional with a positive slope".
Rationale: it is does not cut across the point of origin, and also the slope slants upward from left to the right. Therefore, it is a non-proportional graph with a positive slope.

The answer is 8
Step-by-step explanation:
Because 4x12 is 48 and so is 6x8
Answer:
C. 8
Step-by-step explanation:
4 ⋅ 12 = 6n (6 ⋅ n is the same as 6n)

Step-by-step explanationSomeone bought a car for $5,000. During the first year, its value depreciated by 20%. What was the value of the car after one year?
Answer:
The value of the car after one year is $1000
Step-by-step explanation:
$5000 * 0.2 = 1000.
You can say the 20% = 0.2.
So it is depreciated by 0.2.
You multiply the number (5000) by 0.2
5000 * 0.2 = 1000.
Answer:
The answer is 1,000
Step-by-step explanation:
because 20% of 5000 is the answer which is 1,000

Write a polynomial fx that satisfies the given conditions. Express the polynomial with the lowest possible leading positive integer coefficient.
Polynomial of lowest degree with lowest possible integer coefficients, and with zeros 5-32i and 0 (multiplicity 4).
f(x)=________
Answer:
Step-by-step explanation:
Find the question attached.
Given the zero of the polynomial 5+3i and 0, this means that (x-0) and (x-(5+3i)) are factors
Multiplying the factors together we have;
= x((x-(5+3i))
= x(x-5-3i)
= x²-5x-3xi
Hence the polynomial expression of the zeros is x²-5x-3xi

The coordinates of the point 3/10 of the way from A(-3,-8) to B(11,4) are ___?
Answer:
The coordinate of the point 3/10 of the way from A to B = (0.5, -4.4)
Step-by-step explanation:
to calculate the point 3/10 of the way from A to B, let us first find the difference in the coordinates of the point
Change in x coordinate: x₁ = -3, x₂ = 11
= x₂ - x₁ = 11 - (-4) = 11 + 4 = 15
3/10 of 15 = 0.3 × 15 = 4.5
This means that the point on the x axis is 4.5 points away from x₁
= -4 + 4.5 = 0.5
Change y coordinate: y₁ = -8, y₂ = 4
= y₂ - y₁ = 4 - (-8) = 4 + 8 = 12
3/10 of 12 = 0.3 × 12 = 3.6
This means that the point on the y axis is 3.6 points away from y₁
= -8 + 3.6 = -4.4
Therefore the coordinate of the point 3/10 of the way from A to B = (0.5, -4.4)
6. Find CA*
Please help it’s so confusing
Answer:
The answer is 19.
Step-by-step explanation:
3x+1+12=9x+1
3x+13=9x+1
13=6x+1
12=6x
x=2
3(2)+1+12=19
Answer:
CA = 19
Step-by-step explanation:
3x + 1 + 12 = 9x + 1
combine like terms
3x + 13 = 9x + 1
Subtraction property of equality
3x - 3x + 13 = 9x - 3x + 1
13 = 6x + 1
Subtraction property of equality
13 - 1 = 6x + 1 - 1
12 = 6x
Division property of equality
12/6 = 6x/6
2 = x
Symmetric property of equality
x = 2
Substitute x for 2
9(2) + 1 = 19
Use the limit definition to find an equation of a tangent line of f(x)= 1/(x-1) at the given point (2,1)
By "limit definition", I assume you mean the derivative. We have
[tex]f'(c) = \displaystyle\lim_{x\to c}\frac{f(x)-f(c)}{x-c}[/tex]
For [tex]f(x)=\frac1{x-1}[/tex] and c = 2, we have
[tex]f'(2)=\displaystyle\lim_{x\to2}\frac{\frac1{x-1}-1}{x-2}[/tex]
[tex]f'(2)=\displaystyle\lim_{x\to2}\frac{\frac{1-(x-1)}{x-1}}{x-2}[/tex]
[tex]f'(2)=\displaystyle\lim_{x\to2}\frac{2-x}{(x-1)(x-2)}[/tex]
[tex]f'(2)=\displaystyle\lim_{x\to2}\frac1{1-x}=-1[/tex]
The tangent line to (2, 1) has slope -1. Using the point-slope formula, it has equation
y - 1 = - (x - 2)
y = - x + 3
Use inductive reasoning to predict the next three numbers in the pattern.
Home
3, 5, 8, 13, 21, 34, ...
nents
Predict the next three numbers in the pattern.
3, 5, 8, 13, 21, 34,
Answer:
The next three terms are 55,89 and 144
Step-by-step explanation:
We want to predict the next three numbers in the pattern
3, 5, 8 , 13 , 21 , 34
The difference between two successive terms is written between them.
Thus, we have
3 2 5 3 8 5 13 8 21 13 34
So the rule here is to add the next term to the previous so as to get the next coming term
Thus, we have;
34 + 21 = 55
55 + 34 = 89
89 + 55 = 144
