Answer:

About 27 calendars per week

Step-by-step explanation:

I divided 60 by 7 because there are 7 days in and week and got 8.5 which I round up by 9. I did the same with 123 and got 17.5 which I round up to 18. By adding them together, they sell 27 averagely per week.

Answer:

40°

Step-by-step explanation:

angle FIH =360°-152°-127°=360°-280°=80°

angle FGH = angleFIH ÷2 =40°

Answer:

The answer would be 11.3

Step-by-step explanation:

All you have to do is figure out how far one is from the other so from 7.8 I went back to 0 of course the Y coordinate stays the same. So then you get the -3.5 make it a positive so just 3.5 and then add to 7.8 to get 11.3

Hope this helped.

Step-by-step explanation:

negatives reflected over x axis

Using the given table of transforms,

[tex]L\left\{ y'' - y' - 2y \right\} = L\left\{ 1-x \right\}[/tex]

[tex](s^2 Y(s) - sy(0) - y'(0)) - (s Y(s) - y(0)) - 2 Y(s) = \dfrac1s - \dfrac1{s^2}[/tex]

(where Y(s) is the Laplace transform of y(x))

Solve for Y(s) :

[tex](s^2 - s - 2) Y(s) - s = \dfrac1s - \dfrac1{s^2}[/tex]

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

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

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

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

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

Decompose the right side into partial fractions:

[tex]Y(s) = \dfrac as + \dfrac b{s^2} + \dfrac c{s+1} + \dfrac d{s-2}[/tex]

Solve for the coefficients.

[tex]\implies s^3 + s - 1 = as(s+1)(s-2) + b(s+1)(s-2) + cs^2(s-2) + ds^2(s+1)[/tex]

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

[tex]\implies \begin{cases}-2b = -1 \\ -2a-b = 1 \\ -a+b-2c+d = 0 \\ a+c+d = 1 \end{cases} \implies a=-\dfrac34, b=\dfrac12, c=1, d=\dfrac34[/tex]

Then

[tex]Y(s) = -\dfrac34 \times \dfrac1s + \dfrac12 \times \dfrac1{s^2} + \dfrac1{s+1} + \dfrac34 \times\dfrac1{s-2}[/tex]

Take the inverse transform and solve for y(x) :

[tex]F(s) = \dfrac1s \implies f(x) = 1[/tex]

[tex]F(s) = \dfrac1{s^2} \implies f(x) = x[/tex]

Using the frequency-shifting property,

[tex]F(s) = \dfrac1{s+1} \implies f(x) = e^{-x}[/tex]

[tex]F(s) = \dfrac1{s-2} \implies f(x) = e^{2x}[/tex]

So, the particular solution to the ODE is

[tex]\boxed{y(x) = -\dfrac34 + \dfrac x2 + e^{-x} + \dfrac{3e^{2x}}4}[/tex]

Using the normal distribution, it is found that the minimum table clearance required to satisfy the requirements of fitting 95% of men is of 23.6 in.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, for men's knee heights, we have that:

The 95th percentile is X when Z has a p-value of 0.95, so X when Z = 1.645, then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{X - 21.8}{1.1}[/tex]

[tex]X - 21.8 = 1.1(1.645)[/tex]

[tex]X = 23.6[/tex]

The minimum table clearance required to satisfy the requirements of fitting 95% of men is of 23.6 in.

Step-by-step explanation:

Julia has determined that CE is perpendicular bisector of AB. The next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.

The perpendicular bisector theorem states that if a point is located on a segment (perpendicular bisector) that divides another segment into two halves, then it is equidistant from the two endpoints of the segment that is divided.

Thus, since Julia has determined that CE is perpendicular bisector of AB, therefore the next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.

Answer:

y = 7

Step-by-step explanation:

Linear equation:  y = mx + b

where m is the slope and b is the y-intercept

If the line has a slope of zero, then:  y = b

As the line passes through the point (-2, 7), then y = 7 since the y-coordinate of the point is 7

Answer:

i think the radius is 9 because the diameter of the pool is 18 and the pool is in the shape of a circle so 9 is the best estimate.

Step-by-step explanation:

Answer:

(0, 1)

Step-by-step explanation:

The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.

Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.

Answer:

y-intercept is (0,1)

Step-by-step explanation:

When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis

We can see this in the chart but if that point is not on there, we have another way to find it.

This is the formula, point-slope form.

(Math people are not that creative, you use it when you have the slop and a point)

First, we need to find the slope

We do this by taking two points and using the formula y2-y1 over (/) x2-x1

So our formula is y2-y1/x2-x1.

If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope

3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point

So our equation now is 3-1/x2-x1

Now we have to sub in for the x’s

Do the same thing and our equation now is…

3-1/1-0

This gets us to 2/1 which is obviously 2.

Now we have our slope so we just have to fill in for the point.

Point slope form uses the model y-y1=m(x-x1)

So we use our same two points and get

Y-1=2(x-0)

Solve this out to Slope intercept form which will give us our y-intercept.

This gets us to y=2x+1 so our y-intercept is clearly still 1!

For every 3 dogs, there are 4 cats.

There are 4 cats and 3 dogs, so that means for every 3 dogs, there will be 4 cats.

For every ___3_____ dogs, there are _____4___ cats.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given,

ratio of dogs to cats = 3:4

which means there are 3 dogs per 4 cats.

Answer:

B. AC

Step-by-step explanation:

[i] … … … x + 3y - z = 9

[ii] … … … 2x + 9y + 4z = 12

[iii] … … … x + 4y + z = 7

Eliminate z by combining …

• … 4 times equation [i] and equation [ii] :

4 (x + 3y - z) + (2x + 9y + 4z) = 4•9 + 12

(4x + 12y - 4z) + (2x + 9y + 4z) = 36 + 12

6x + 21y = 48

2x + 7y = 16

• … equation [i] and equation [iii] :

(x + 3y - z) + (x + 4y + z) = 9 + 7

2x + 7y = 16

Since we ended up with 2 copies of the same equation, we have infinitely many solutions for x, y, and z. That is, we have infinitely many choices for x and y that satisfy 2x + 7y = 16, and consequently infinitely many choices for z to satisfy any of the 3 original equations.

We can parameterize the solution by letting, for instance, x = t; then the solution set is

x = t

2x + 7y = 16   ⇒   y = (16 - 2t)/7

x + 3y - z = 9   ⇒   z = t + 3 (16 - 2t)/7 - 9   ⇒   z = (t - 15)/7

where t is any real number.

hii good morning the answer is (-6, 3)

Answer:

Step-by-step explanation:

As we can see that Line WL is a straight line that the angles that make up it like Angle HJW and Angle GJH and Angle LJG all equal to 180 degrees

Angle HJW = 18 degrees

ANGLE GLH = 90 degrees (we know that because there is a little square)

Angle LJG = 9x

Now lets set up the equation:

 Angle HJW + Angle GLH + ANGLE LJG = 180 degrees

  18 + 90 + 9x = 180

    108 + 9x = 180  

                9x = 72

               x = 8

So x = 8
