What is 248 divided by 3?
Answer:
82.6666666667 or just 82.67
Step-by-step explanation:
The value of 248 ÷ 3 equals 82.
To divide 248 by 3, we set up the division equation: 248 ÷ 3.
Starting with the first digit of 248, which is 2, we check how many times 3 can be divided evenly into 2. Since 3 is larger than 2, we move on to the next digit, 24.
Now, we divide 24 by 3, which gives us 8.
Next, we bring down the next digit, 8, making the current dividend 88.
We divide 88 by 3, resulting in a quotient of 29.
Since there are no more digits to bring down, the division is complete.
Therefore, 248 ÷ 3 equals 82.

The given function has a domain of {-4, -2, 0, 2, 4} Find the function's range.
f(x) = 2x - 1
{-4, -2, 0, 2, 4}
{9, 5, 1, 3, 7}
{-9, -5, -4, -2, -1, 0, 2, 3, 4, 7}
{-9, -5, -1, 3, 7}
Answer:
The range of the function will be: {-9, -5, -1, 3, 7}
Step-by-step explanation:
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.Given the function
f(x) = 2x - 1
Given that the domain of the function is:
{-4, -2, 0, 2, 4}
Putting x=-4
f(x) = 2x - 1
f(-4)= 2(-4)-1=-8-1=-9
Thus,
at x=-4, y = -9
Putting x=-2
f(x) = 2x - 1
f(-2)= 2(-2)-1=-4-1=-5
Thus,
at x=-2, y = -5
Putting x=0
f(x) = 2x - 1
f(0)= 2(0)-1=0-1=-1
Thus,
at x=-2, y = -1
Putting x=2
f(x) = 2x - 1
f(2)= 2(2)-1=4-1=3
Thus,
at x=-2, y = 3
Putting x=4
f(x) = 2x - 1
f(4)= 2(4)-1=8-1=7
Thus,
at x=-2, y = 7
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
Thus, the range of the function will have all the y values correspond to all the x values for which the function is defined.
Thus, the range of the function will be: {-9, -5, -1, 3, 7}

Answer the question below:
Helpp!!!
(1-sin2A)(1+cot2A)=cot2A
This isn't an identity, so I assume you have to solve the equation.
(1 - sin(2A)) (1 + cot(2A)) = cot(2A)
1 - sin(2A) + cot(2A) - sin(2A) cot(2A) = cot(2A)
1 - sin(2A) - cos(2A) = 0
sin(2A) + cos(2A) = 1
Multiply both sides by 1/√2, which we want to do because cos(π/4) = sin(π/4) = 1/√2. This gives
cos(π/4) sin(2A) + sin(π/4) cos(2A) = 1/√2
Then condense the left side as
sin(2A + π/4) = 1/√2
2A + π/4 = sin⁻¹(1/√2) + 2nπ or 2A + π/4 = π - sin⁻¹(1/√2) + 2nπ
(where n is any integer)
2A + π/4 = π/4 + 2nπ or 2A + π/4 = 3π/4 + 2nπ
2A = 2nπ or 2A = π/2 + 2nπ
A = nπ or A = π/4 + nπ

A beach ball is inflated so its diameter increases from 12 inches to 12.5 inches. Given that the formula for the volume of a sphere is V=4/3π,r^3 the change in the volume of the beach ball using differentials is approximately.
a. 367π cubic inches.
b. 727π cubic inches.
c. 1447π cubic inches.
d. 288.7π cubic inches.
Answer:
V = 36π cubic inches.
Step-by-step explanation:
Given that:
The volume of the sphere is [tex]V = \dfrac{4}{3} \pi r^3[/tex]
If the diameter is represented by P.
Then P = 2r
and r = P/2
∴
[tex]V = \dfrac{4}{3} \pi ( \dfrac{P}{2})^3[/tex]
By differentiating both sides;
[tex]dV = \dfrac{4}{3} \pi \times 3 ( \dfrac{P}{2})^2 \times \dfrac{1}{2} \times dP[/tex]
[tex]dV = \dfrac{1}{2} \pi P^2 \ dP[/tex]
where;
P = 12
dP = 12.5 - 12
dP = 0.5
Then;
[tex]\dfrac{1}{2} \pi ( 12)^2 \times 0.5[/tex]
= 36π
Thus, the volume is V = 36π cubic inches.

Whitney was visiting Big Bend Ranch
State Park. At the entrance, she saw a
map of the park. The legend stated
that 1.5 inches on the map represents
20 feet in the park. On the map, how
many inches would represent 60
actual feet?
Answer:
4.5 inches on the map would represent 60 actual feet.
Step-by-step explanation:
Given that:
1.5 inches on map represents 20 feet in the park.
x be the inches on map that represents 60 feet in the park.
Ratio of distance on map to actual distance :: Ratio of distance on map to actual distance
1.5 : 20 :: x : 60
Product of mean = Product of extreme
20*x = 1.5*60
20x = 90
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{90}{20}\\x=4.5[/tex]
Hence,
4.5 inches on the map would represent 60 actual feet.
What is the answer for 34-54x
Answer:
2(17-27x)
Step-by-step explanation:
Since the question was incomplete this is the only answer I have for you.
If you were looking for the answer of X I would need a answer for the equation
Anyways... you want to factor out 2 from the expression since there are two numbers
Once you factored out the two (divide each number by 2) you'll get:
2(17-27x)
Answer:
The answer is 34-54x because there are no like terms. 34 has no like terms and neither does 54x, so the answer is just 34-54x.
