Answer:

-12

Step-by-step explanation:

Step 1: Add 18 to both sides.

−2x−18+18=6+18

−2x=24

Step 2: Divide both sides by -2.

−2x

−2

=

24

−2

x=-12

Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. Whi
Dafna1 [17]
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20

It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3

9 m<br> 3 m<br> 3 m<br> What is the area, in square meters, of the shaded region in the diagram?
NeTakaya

Answer:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius2  =  pi * (19m)2  =  pi * 361 m2   ≈   1133.54 m2

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m2     -  1133.54 m2

area of shaded region  ≈    310.46 m2

Step-by-step explanation:

Notice that the side length of the square is  38 m.

area of square  =  (side length)2  =  (38 m)2   =   1444 m2

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius2  =  pi * (19m)2  =  pi * 361 m2   ≈   1133.54 m2

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m2     -  1133.54 m2

area of shaded region  ≈    310.46 m2

When a certain prescription drug is taken orally by an adult, the amount of the drug (in mg/L) in the bloodstream at t hours is
castortr0y [4]

Answer:

1. y = f(8)

2. So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.

Step-by-step explanation:

The concentration of the drug in the bloodstream at t hours is:

y = f(t)

1. What is the concentration of the drug in the bloodstream at t= 8 hours?

At t hours, y = f(t)

So at 8 hours, y = f(8)

2. During what time interval is the drug level in the bloodstream increasing? Decreasing?

A function f(t) is increasing when

f'(t) > 0

And is decreasing when

f'(t) < 0

So for t which f'(t) > 0, the drug level in the bloodstream is increasing. And for t which f'(t) < 0, it is decreasing.

If a parallelogram is reduced to have dimensions that are half as long, then the perimeter is one fourth the original length. Tr
Elena-2011 [213]

The statement is false.


If a parallelogram is reduced to have dimensions that are half as long, then the perimeter isalso half the original length.


If you imagine a square with sid lengths of 4, the original perimeter is 16. When the dimensions are halved to be 2, the new perimeter is 8. 8 is half of 16, not a fourth of 16.

What's the best way to solve that? I'm not understanding the whole LCD part
Nadya [2.5K]
So it's  \frac{3p - 5}{2} = \frac{4p+24}{3}.

Then you cross-multiply, so then we have 9p - 15 = 8p + 48. Now just solve. 


Answer is p = 63.
