Can you guys help me out ps hurry im timed

Answer:

448

Step-by-step explanation:

[tex](p1)(q1)^2=p2(q2)^2\\p1(2)^2=28(8)^2\\p1=(4)=28(64)\\4p1=1792/4\\p1=448[/tex]

Value of [tex]\boldsymbol{pp}[/tex] is [tex]\boldsymbol{\frac{112}{9}}[/tex]

[tex]pp[/tex] is inversely proportional to the square of [tex]qq[/tex]

So,

[tex]\boldsymbol{pp=\frac{(qq)^2}{k}}[/tex] where [tex]k[/tex] is a constant.

Put [tex]pp=28,qq=3[/tex]

[tex]28=\frac{3^2}{k}\\28=\frac{9}{k}[/tex]

[tex]\boldsymbol{k=\frac{9}{28}}[/tex]

So,

[tex]pp=\frac{28}{9}(qq)^2[/tex]

Put [tex]qq=2[/tex]

[tex]pp=\frac{28}{9}(2)^2\\ pp=\frac{112}{9}[/tex]

So, value of [tex]\boldsymbol{pp}[/tex] is [tex]\boldsymbol{\frac{112}{9}}[/tex]

Answer:

The value of g(a) is:

[tex]g(a) = 3 - 2a[/tex]

Step-by-step explanation:

Given

As the function is given by

[tex]g(x)=3-2x[/tex]

To determine

g(a) = ?

Given the function

[tex]g(x)=3-2x[/tex]

substitute x = a in the function

[tex]g(a) = 3 - 2(a)[/tex]

[tex]g(a) = 3 - 2a[/tex]

Therefore, the value of g(a) is:

This problem can be translated to:

A man bought N pens, (at a cost C) if he sells each pen at 2 lira, he will have a profit of 40 lira.

If he sells each pen at 1.5 lira, he will loss a total of 20 lira.

We want to find N, the number of pens that he bought.

if he sells the N pens at 2 lira each, the revenue is:

N*2 lira

And the profit is the difference between the revenue and the cost, then the profit (40 lira in this case) is:

N*2 lira - C = 40 lira.

When he sells each pen at 1.5 lira the equation is:

N*(1.5 lira) - C = -20 lira.

Then we have two equations:

N*2 lira - C = 40 lira.

N*(1.5 lira) - C = -20 lira.

To solve this we need to isolate the variable C in one of the equations, i will isolate C in the second equation:

N*(1.5 lira) + 20 lira = C.

Now we can replace this in the first equation to get:

N*(2 lira) - (N*(1.5 lira) + 20 lira) = 40 lira.

We can solve this for N.

N*(2 lira) - N*(1.5 lira) - 20 lira = 40 lira

N*(2 lira - 1.5 lira) = 60 lira

N*(0.5 lira) = 60 lira

N = (60lira/0.5lira) = 120

N = 120

This means that he bought 120 pens.

The correct option is B.

Answer:

  11.  (-4, -1)

  12.  (2, 7)

Step-by-step explanation:

The midpoint is the average of the end point coordinates. For segment AB, the midpoint M is ...

  M = (A+B)/2

If you have A and M, you can find the other end point B from ...

  2M = A+B . . . . multiply the above equation by 2

  B = 2M -A . . . . subtract A from both sides

__

11. The midpoint (M) is ...

  M = ((-1, 2) +(-7, -4))/2 = (-1-7, 2-4)/2 = (-8, -2)/2

  M = (-4, -1)

__

12. The missing end point is ...

  Z = 2Y -X

  Z = 2(-4, 8) -(-10, 9) = (2(-4)+10, 2(8) -9)

  Z = (2, 7)

Answer:

T-shirts: 200

Shorts: 50

Step-by-step explanation:

To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold.  Let x = t-shirts sold. Let y = shorts sold.  2x + 4y = 600.    We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories.  My first guess was 50 shorts, which by luck was the correct answer.  These problems can be tricky, but setting up an equation can prove to be a great help.

Step-by-step explanation:

Recall this is a rational function with vertical asymptotes at the points where the denominator becomes zero. That is:

for x = -2 (that brings x+2 = 0)  and for x = 3 (that brings x - 3 = 0)

Therefore, select answer b).
