Answer:
The length of the rectangle is 30 cm, and the width of the rectangle is 18 cm.
Step-by-step explanation:
Since the wire is shaped as a rectangle, and we need perimeter for this problem, we can use the equation (l+w)*2, and the perimeter is 96, where l is the length and w is the width.
Since the length is 12 cm longer than the width, then we have:
W + 12 = L
Now substitute for the L in our equation and solve.
(w+12+w)*2 = 96
(2w + 12) *2 = 96
Multiply using the distributive property
4w + 24 = 96
4w = 72
w = 18
Now plug in the w for our second equation:
18 + 12 = L
30 = L
Now check our answer by plugging it in our old equation:
(18+30)*2 = 96
48*2 = 96
96 = 96
Our answer is correct, so the length of the rectangle is 30 cm, and the width of the rectangle is 18 cm. Hope this helps.

Huilan is 8 years older than Thomas. The sum of their ages is 70. What is Thomas's age?
Answer:
T = 31
Step-by-step explanation:
(T + 8) + T = 70
subtract 8 from both sides
T+T = 62
Rewrite
2T = 62
divide both sides by 2
T = 31

What is the factored form for the quadratic function?
Answer:
Step-by-step explanation:
The factored form of a quadratic function is f (x) = a (x - p) (x - q) where p and q are the zeros of f (x).
Evaluate the expression 3× 2t if t equals 4
∫(2x^3-x^2-2x+4)/(1+x^2)dx
Simplify the integrand as
[tex]\dfrac{2x^3 - x^2 - 2x + 4}{1 + x^2} = \dfrac{(2x^3 + 2x) - (x^2 + 1) - 4x + 5}{x^2 + 1} \\\\ = \dfrac{2x(x^2 + 1) - (x^2 + 1) - 4x + 5}{x^2 + 1} \\\\ = 2x - 1 - \dfrac{4x - 5}{x^2 + 1}[/tex]
(in other words, compute the quotient and remainder)
We can further split up and prepare the remainder term for integration by rewriting it as
[tex]\dfrac{4x - 5}{x^2 + 1} = 2\times\dfrac{2x}{x^2 + 1} - \dfrac5{x^2 + 1}[/tex]
Now we integrate:
[tex]\displaystyle \frac{2x^3 - x^2 - 2x + 4}{1 + x^2} \, dx = \int \left(2x - 1 - 2\times\frac{2x}{x^2+1} + \frac5{x^2+1}\right) \, dx[/tex]
[tex]\displaystyle = x^2 - x - 2 \int \frac{2x}{x^2+1} \, dx + 5 \int \frac{dx}{x^2+1}[/tex]
In the first remaining integral, substitute y = x² + 1 and dy = 2x dx. In the last integral, recall that d/dx [arctan(x)] = 1/(x² + 1).
[tex]\displaystyle = x^2 - x - 2 \int \frac{dy}y + 5 \int \frac{dx}{x^2+1}[/tex]
[tex]\displaystyle = x^2 - x - 2 \ln|y| + 5 \arctan(x) + C[/tex]
[tex]\displaystyle = \boxed{x^2 - x - 2 \ln(x^2+1) + 5 \arctan(x) + C}[/tex]

Which function represents a parabola that is translated 2 units to the left and 6 units down from the parent function, f(x)=x^2
Translation involves moving a function along its coordinates
The image of the function is [tex]g(x) = (x + 2)^2 - 6[/tex]
How to determine the new functionThe parent function is given as:
[tex]f(x) = x^2[/tex]
When the function is translated 2 units left, we have:
[tex]f'(x) = (x + 2)^2[/tex]
When the function is translated 6 units down, we have:
[tex]f"(x) = (x + 2)^2 - 6[/tex]
Rewrite as:
[tex]g(x) = (x + 2)^2 - 6[/tex]
Hence, the image of the function is [tex]g(x) = (x + 2)^2 - 6[/tex]

Answer:
[tex]\huge\boxed{\sf{b=55\:(b=y-intercept\:;)}}[/tex]
Step-by-step explanation:
Hello.
The y-intercept of a line is a point where the graph touches the y-axis.
Y-intercepts always have an x-coordinate of 0.
Now, what is the y-intercept?
If we have a point (0, b) then b is the y-intercept.
This is just a formula, so don't think that the y-intercept is b, okay?
The y-intercept is b, but only in formulae. :)
Using the formula, we can deduce that
the y-intercept is 55.

====================================================
Explanation:

If it has an inequality sign of one of the following [tex]< , \ > , \ \le, \ \ge[/tex], then it's an inequality.
Otherwise, it's an expression.
Problem 0: Compute the inverse Laplace Transforms of:
[tex]F(s) = \frac{s + 1}{s(s - 1)(s - 3)} [/tex]
[tex]F(s) = \frac{1}{(s - 1)(s - 2)(s - 3)} [/tex]
Decompose each given F(s) into partial fractions.
[tex]F(s) = \dfrac{s+1}{s(s-1)(s-3)}[/tex]
has partial fraction decomposition
[tex]\dfrac{s+1}{s(s-1)(s-3)} = \dfrac as + \dfrac b{s-1} + \dfrac c{s-3}[/tex]
Combine the rational terms on the right and solve for the coefficients:
[tex]\dfrac{s+1}{s(s-1)(s-3)} = \dfrac{a(s-1)(s-3) + b s(s-3) + c s(s-1)}{s (s-1) (s-3)}[/tex]
[tex]1 = a(s-1)(s-3) + bs(s-3) + c s(s-1)[/tex]
[tex]1 = 3 a + (-4 a - 3 b - c) s + (a + b + c) s^2[/tex]
[tex]\begin{cases}3a=1 \\ -4a-3b-c = 0 \\ a+b+c=0 \end{cases} \implies a=\dfrac13, b=-\dfrac12, c=\dfrac16[/tex]
Then
[tex]F(s) = \dfrac13 \times \dfrac1s - \dfrac12 \times \dfrac1{s-1} + \dfrac16 \times \dfrac1{s-3}[/tex]
Using the frequency-shifting property, the inverse transform is
[tex]\boxed{f(t) = \dfrac13 - \dfrac{e^t}2 + \dfrac{e^{3t}}6}[/tex]
The other transform can be dealt with in the same manner.
[tex]F(s) = \dfrac1{(s-1)(s-2)(s-3)} = \dfrac a{s-1} + \dfrac b{s-2} + \dfrac c{s-3}[/tex]
[tex]\implies 1 = a(s-2)(s-3) + b(s-1)(s-3) + c(s-1)(s-2)[/tex]
[tex]\implies 1 = 6 a + 3 b + 2 c + (-5 a - 4 b - 3 c) s + (a + b + c) s^2[/tex]
[tex]\implies \begin{cases}6 a + 3 b + 2 c=1 \\ -5a-4b-3c = 0 \\ a+b+c=0\end{cases} \implies a=\dfrac12, b=-1, c=\dfrac12[/tex]
[tex]\implies F(s) = \dfrac12 \times \dfrac1{s-1} - \dfrac1{s-2} + \dfrac12 \times \dfrac1{s-3}[/tex]
[tex]\implies \boxed{f(t) = \dfrac{e^t}2 - e^{2t} + \dfrac{e^{3t}}2}[/tex]
Let f(x)=cos(x)x^-2
F’(x)=
[tex]f(x)=cos(x)x^{-2}\implies f(x)=\cfrac{cos(x)}{x^2}\implies \cfrac{df}{dx}=\stackrel{\textit{quotient rule}}{\cfrac{-sin(x)\cdot x^2-cos(x)\cdot 2x}{(x^2)^2}} \\\\\\ \cfrac{df}{dx}=\cfrac{-x[x\cdot sin(x)+2cos(x)]}{x^4}\implies \cfrac{df}{dx}=\cfrac{-[xsin(x)+2cos(x)]}{x^3}[/tex]
