Answer:

No

Step-by-step explanation:

To calculate how much fence is needed we need to calculate the perimeter NOT area.

P = 2L+2W

P =2(6.75)+2(4 2/3)

P = 13.5 + 9 1/3

P = 22 5/6

Because she only has 22 yards she does not have enough to go all the way around.
Hope this helps and brainliest please

Answer:

Adult tickets are $14

Student tickets are $8

Step-by-step explanation:

let's say that [tex]\tt s=student~ticket\\\\[/tex]

And [tex]\tt a=adult~ticket[/tex]

on the first day we have:

[tex]\tt 3s+a=38[/tex]

On the second day we have

[tex]\tt3s+2a=52[/tex]

now we have a system of 2 equations with 2 unknown

[tex]\tt 3s+a=38[/tex]

[tex]\tt 3s+2a=52[/tex]

we will multiply the first equation with -1

[tex]\tt -3s-a=-38\\\tt ~3s+2a=52[/tex]

we solved the system and

a= $14,  forthe adult ticket

s= $8 for the student ticket

Have an Awesome day!

Transforming the ODE yields

[tex]L\left\{y'' - y'\right\} = L\left\{e^{-3t}\right\}[/tex]

[tex](s^2 Y(s) - sy(0) - y'(0)) - (s Y(s) - y(0)) = \dfrac1{s+3}[/tex]

[tex](s^2 - s) Y(s) = \dfrac1{s+3}[/tex]

[tex]Y(s) = \dfrac1{(s^2 - s)(s+3)} = \dfrac1{s(s-1)(s+3)}[/tex]

Partial fractions:

[tex]Y(s) = \dfrac as + \dfrac b{s-1} + \dfrac c{s+3}[/tex]

[tex]\implies 1 = a(s-1)(s+3) + b s(s+3) + c s(s - 1)[/tex]

[tex]\implies 1 = -3 a + (2 a + 3 b - c) s + (a + b + c) s^2[/tex]

[tex]\implies \begin{cases}-3a=1 \\ 2a+3b-c=0 \\ a+b+c=0\end{cases} \implies a=-\dfrac13, b=\dfrac14, c=\dfrac1{12}[/tex]

[tex]\implies Y(s) = -\dfrac13 \times \dfrac1s + \dfrac14 \times \dfrac1{s-1} + \dfrac1{12} \times \dfrac1{s+3}[/tex]

Take the inverse transform:

[tex]\boxed{y(t) = -\dfrac13 + \dfrac{e^t}4 + \dfrac{e^{-3t}}{12}}[/tex]

Step-by-step explanation:

Answer:

Dilate, Reflect

Not congruent, dilations are used

Step-by-step explanation:

Dilate Figure K by a factor 3 to get the white shape.

Reflecting the resulting figure over the x-axis will give you Figure L

Step 1: Dilate by a scale factor of 3

Step 2: Reflect over the x-axis

Since dilations are used, the shapes are not congruent as they change the side lengths and area.

Answer:

∠B = 17°

Step-by-step explanation:

Los ángulos verticales son congruentes, por lo tanto

5x + 7 = x + 15 ( restar x de ambos lados )

4x + 7 = 15 ( resta 7 de ambos lados )

4x = 8 ( dividir ambos lados por 4 )

x = 2

Por lo tanto

∠B = 5x + 7 = (5 × 2) + 7 = 10 + 2 = 17°

The equation for function 1 is in slope-intercept form by which we can identify the y-intercept easily..

[tex]y = mx + b[/tex]

Where,

Compare to the given equation:

[tex] - 5 \cancel= - 7[/tex]

Therefore, Function 2 has greater y-intercept...~

For function 1

Compare with y=mx+b

Function 2 has greater y intercept.

Using the uniform distribution, it is found that the mathematical expression for the probability density function of battery recharging time for this scenario is given by:

[tex]f(x) = \frac{1}{40}, 70 \leq x \leq 110[/tex]

[tex]f(x) = 0[/tex], elsewhere.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability density function is:

[tex]f(x) = \frac{1}{b - a}, a \leq x \leq b[/tex]

[tex]f(x) = 0[/tex], elsewhere.

In this problem, the actual recharging time required is uniformly distributed between 70 and 110 minutes, hence a = 70, b = 110, and the density function is:

[tex]f(x) = \frac{1}{40}, 70 \leq x \leq 110[/tex]

[tex]f(x) = 0[/tex], elsewhere.

Answer:

65 in

Answer:

B

Step-by-step explanation:

x² - 6x = 0

x² - 6x + (6/2)² = (6/2)²

x² - 6x + 9 = 9

(x - 3)² = 9

So B

The lower limit of the integral is -∞, since √n - √(n + 1) ≤ -1 for all n, and

[tex]\displaystyle\sum_{n=0}^\infty (\sqrt n - \sqrt{n+1}) = -\sum_{n=0}^\infty\dfrac1{\left|\sqrt n + \sqrt{n+1}\right|} \ge -\sum_{n=0}^\infty \frac1{n^{1/2}}[/tex]

and the sum on the right is a divergent p-series.

The upper limit of the integral is ln(2). Recall that for |x| < 1,

[tex]\displaystyle \sum_{n=0}^\infty x^n = \frac1{1-x}[/tex]

Integrating both sides gives

[tex]\displaystyle \sum_{n=0}^\infty \frac{x^{n+1}}{n+1} = -\ln(1-x) + C[/tex]

When x = 0, it follows that C = 0. As x → -1 from above, we find

[tex]\displaystyle \sum_{n=0}^\infty \frac{(-1)^n}{n+1} = \ln(2)[/tex]

The limit in the integrand is e, since

[tex]\displaystyle \lim_{t\to\infty}\left(1+\frac1{e^t}\right)^{e^t} = \lim_{n\to\infty}\left(1+\frac1n\right)^n = e[/tex]

where we replace n = eᵗ, so both n and t → ∞.

The derivative in the exponent of the integrand is

[tex]\dfrac{d}{dx}\dfrac{x^2}{\sin^2(x)+\cos^2(x)} = \dfrac{d}{dx}x^2 = 2x[/tex]

So, the original expression simplifies significantly to

[tex]\left(\displaystyle \int_{-\infty}^{\ln(2)} e^{2x} \, dx\right)^2[/tex]

The remaining integral is trivial:

[tex]\displaystyle \int_{-\infty}^{\ln(2)} e^{2x} \, dx = \frac12 e^{2\ln(2)} = 2[/tex]

and so the expression has a value of 2² = 4.

A triangle has three sides, the first, second, and the add up to 24, since that's the perimeter

The second side = the first (let's call it L) + 2

The third is two more then the second, so L + 2 + 2

first side = L

second = L + 2

third = L + 2 + 2

add all three together, L + L + 2 + L + 2 + 2 = 24

combine the L's and 2's

3L + 6 = 24

subtract 6 from both sides

3L = 18

divide by 3

L=6

so the first side is 6, the second is 8, the third is 10
