Answer:
6.28 km
Step-by-step explanation:
Circumference formula:
C = 2πr
To find r:
r = d/2
r = 2/2
r = 1
Work:
C = 2(3.14)(1)
C = 6.28
Answer:
6.28
Step-by-step explanation:
Its the formula 2πr. The diameter is 2 and the radius is half of 2 so 1. Just plug in 1 for r and multiply everything together.

Work out the surface area of this solid prism.
9m
10m
6m
8m
Given:
Consider the below figure attached with this question.
To find:
The surface area of this solid prism.
Solution:
The surface area of this solid prism is
[tex]A=P\times h+2B[/tex]
Where, P is the perimeter of the base, B is the area of the base and h is the height of the prism.
Perimeter of the base is:
[tex]P=6+8+10[/tex]
[tex]P=24[/tex]
Area of the base is:
[tex]B=\dfrac{1}{2}\times base\times height[/tex]
[tex]B=\dfrac{1}{2}\times 8\times 6[/tex]
[tex]B=24[/tex]
Putting [tex]P=24[/tex] and [tex]B=24[/tex] in the formula for area, we get
[tex]A=(24)\times 9+2(24)[/tex]
[tex]A=216+48[/tex]
[tex]A=264[/tex]
Therefore, the surface area of the given prism is 264 m².

What is the Slope-Intercept Form of 16x + 4y = 44
Answer:
Y=-4x+11
Step-by-step explanation:
So first you gotta realize that slope intercept from is
y=mx+b
So you have the equation of
16x+4y=44 as the initial response
Now you just have to isolate it into the from of y=mx+b
SO first subtract 16x on both sides to isolate the 4y since its the initial response as y=mx+b
Then when that is done you should have the answer of
4y= 44-16x
Now You have to isolate the “y”.
By dividing 4 on both sides to get the new equation which will be
y= 11-4x
You can leave it like that or just move around the (x) to make it more plausible as the answer of y=mx+b
y= -4x+11
However you would put it, that is the answer
y= -4x+11
And
y= 11-4x

The length of a rectangle is 4x - 5 inches. The width of the rectangle is x + 1 inches.
A) Write a quadratic function equation to model the area of the rectangle.
B) Then evaluate the function for (2).
Answer:
A) A = 4x^2 - x - 5
B) f(2) = 9
Step-by-step explanation:
area is L x W, so you multiply 4x - 5 with x + 1
A = (4x - 5)(x + 1)
which gives you
A = 4x^2 - x - 5
you would then plug in 2 for x which gives you your answer of
9

what is the explicit formula for the sequence above.
Answer:
aₙ=-7*2ⁿ⁻¹
Step-by-step explanation:
The common ratio is r=-28/-14=-14/-7=2
The explicit formula for a geometric sequence is aₙ=a₁*rⁿ⁻¹ where aₙ is the nth term, r is the common ratio, and a₁ is the first term.
Given:
a₁=-7
r=2
Therefore, the explicit formula for the sequence is aₙ=-7*2ⁿ⁻¹
two boys move simultaneously towards each other from two objects located at a distance of 7.5km. The speed of one is as much as 2/3 of the speed of the other. Find the speeds of each if they meet after 1.5 hours
Find the missing term(s) of the geometric sequence: 39, a2 , 975, ... Hint: r can be positive or negative.
9514 1404 393
Answer:
±195
Step-by-step explanation:
For some common ratio r, your missing term satisfies ...
39r = a2
a2·r = 975
So, ...
975 = 39r^2
25 = r^2
r = ±√25 = ±5
The missing term a2 = 39r could be either of 195 or -195.

What is being done to the variable in the equation = -40?
It's being multiplied by -40.
It's being multiplied by -5.
It's being divided by -40.
It's being divided by 5.
Answer:
It's being divided by 5.
Step-by-step explanation:
In this question, the variable being used in the equation is being divided by 5. This is represented by the / symbol in the equation which is the symbol for division. If we multiply both sides by 5 we can isolate the variable M and get its value like so...
M/5 = -40 ... multiply both sides by 5
M = -200
Therefore in this scenario, the value of M would be -200

Answer:
The volume of this figure is approximately 418.88 centimeters squared!
Step-by-step explanation:
The volume for a right circular cone is V = (π)(r^2)(h/3)
Substituting known values is as follows:
V = (π)(r^2)(h/3)
V = (π)(4^2)(25/3)
V = (π)(16)(25/3)
V ≈ 418.88 cm^3
