Answer:
2^2 = 4
4 x 3.14 = 12.56
12.56 x 2 (since there are two circles on the cylinder) = 25.12
Now let's find the circumference of one circle and multiply it by the height to get the round surface area!
2 x 3.14 x 2 = 12.56(circumference)
12.56 x 8(height) = 100.48
Now add both the surface areas!:
25.12 + 100.48 = 125.6 in2 is your answer.
If f(x)= x^1/2 - x and g(x)= 2x^3 - x^1/2 - x, find f(x) - g(x)
Answer:
[tex]-2x^3+2x^{1/2}[/tex]
Step-by-step explanation:
First, you have to substitute both functions into the equation to get:
[tex]f(x)-g(x) = (x^{1/2}-x) - (2x^3-x^{1/2}-x)[/tex]
Then, you distribute the negative sign in front of g(x) to get:
[tex]= x^{1/2} - x -2x^3+x^{1/2}+x[/tex]
And finally, you add/subtract the x's that have the same power to get:
[tex]=-2x^3+2x^{1/2}[/tex]

Joãozinho de Gitana calculadora o número de 12750 Qual é o número que tempo para subtrair para obter como resultado o número 12250
Responder:
500
Explicação passo a passo:
O número a subtrair de 12.750 em outro para obter 12.250
Deixe o número = x
Isso é ; se x for subtraído de 12750; nós obtemos 12250
12750 - x = 12.250
Subtraia 12750 de ambos os lados
12750 - x - 12750 = 12.250 - 12750
-x = - 500
x = 500

What is the value of x
Answer:
x = 36.03°
Step-by-step explanation:
We have to find: Angle A, also called "x
We are given: Side opposite to x and the hypotenuse of the triangle.
Trigonometric Ratio that would be used: Sin
=> Sin(x) = Opposite/Hypotenuse
=> Sin(x) = 10/17
=> x = Sin⁻¹(10/17)
=> x = 36.03 Degrees
Hope this helps!

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.
Answer:
Kayak and Canoe rented for 3 hours
Step-by-step explanation:
Let the time for which they rent canoe & kayak = x hours
Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x
Given] Total canoe & kayak cost = 78.92
So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92
20.49 + 17.99 + 7.49x + 5.99x = 78.92 ; 38.48 + 13.48x = 78.92
13.48x = 78.92 - 38.48 ; 13.48x = 40.44
x = 40.44 / 13.48 ; x = 3

When factoring a trinomial into two binomials, how do you know if you are adding or subtracting the factors of the last term to get the middle term?
Answer:
Write out all the pairs of numbers which can be multiplied to produce c.
Add each pair of numbers to find a pair that produce b when added.
If b > 0, then the factored form of the trinomial is (x + d )(x + e).
Check: The binomials, when multiplied, should equal the original trinomial.

Solve for x. Round your answer to the nearest tenth.
4.8 in
7.4 in
Answer:
5.6
........................................................................
Answer:
x = 5.6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2
4.8 ^2 + x^2 = 7.4^2
23.04 +x^2 =54.76
Subtract 23.04 from each side
x^2 = 54.76 - 23.04
x^2 =31.72
Take the square root of each side
x =5.632051136
Rounding to the nearest tenth
x = 5.6

PLEASE HELP ASAP Find the value of x.
Answer:
x = 9
Step-by-step explanation:
The secant- secant angle 4x° is half the difference of the intercepted arcs, that is
4x = [tex]\frac{1}{2}[/tex] (9x + 26 - 35 ) ← multiply both sides by 2 to clear the fraction
8x = 9x - 9 ( subtract 8x from both sides )
0 = x - 9 ( add 9 to both sides )
9 = x
