Answer:

8

Step-by-step explanation:

The number of adults that are there will be 368 adults.

Let adults = a

Let children = c

The equation to solve the question will be:

a + c = 865 ....... i

30a + 9c = 15513 ...... ii

From equation i, c = 865 - a

Since 30a + 9c = 15513

30a + 9(865 - a) = 15513

30a + 7785 - 9a = 15513

30a - 9a = 15513 - 7785

21a = 7728

a = 7728/21

a = 368

Answer:

y = 46

Step-by-step explanation:

I'm assuming you wanted to solve for y.

x = 5

y = 8(5) + 6

y = 40 +6

y = 46

Answer:

y= -2(-6) +5

y= 12+5

y= 17

y= -2(-3) +5

y= 6 +5

y= 11

y= -2(0) +5

y= 0+5

y=5

y= -2(3) +5

y= -6 +5

y= -1

Step-by-step explanation:

The answer is 2 because 2 is a prime number

If the function f(x) =(4x² tan x)/sec x , then f'(x) =4( 2x sin(x) + x² cos x) using product rule of differentiation and f'(5) =103.11

Product rule for differentiation states that the differentiation the product of two functions is the product of derivative of first function and second function plus  product of derivative of second function and first function.

If we have consider the differentiation of product of two functions u ,v that we can write product rule as

(u*v)' = u' v  + u v' , where '  represents first derivative  with respect to independent variable

Given f(x) = (4x² tan x)/sec x or we can write it as :

f(x) = (4x² )(sin x) as   1/ sec x is cos x , tan x = sin x / cos x

let u =4x² , v = sin x

Then f(x) =u × v

Using product rule of differentiation:

f'(x) =  u' v + u v'  = (8x sin x) + (4x² cos x) = 4( 2x sin(x) + x² cos x)

To find value of f'(x) at x= 5

f'(5) = 4(10sin5 + 25 cos5) = 103.10569951 = 103.11(rounding off )

Therefore if f(x) = (4x² tan x)/sec x  then f'(x) =4( 2x sin(x) + x² cos x) and f'(5) =103.11

Answer:

a

Step-by-step explanation:

because all top numbers can go into bottom numbers.

This is between 2 and 3 seconds, excluding both endpoints.

========================================================

Explanation:

t = elapsed time in seconds

h(t) = height of the ball at time t

Replace h(t) with 100. Then get everything to one side.

[tex]h(t)= -16t^2+80t+4\\\\100= -16t^2+80t+4\\\\0 = -16t^2+80t+4-100\\\\0= -16t^2+80t-96\\\\-16t^2+80t-96 = 0[/tex]

Next, we'll use the quadratic formula to isolate t.

Plug in a = -16, b = 80, c = -96 which are the coefficients of the last equation mentioned above.

[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-80\pm\sqrt{(80)^2-4(-16)(-96)}}{2(-16)}\\\\t = \frac{-80\pm\sqrt{256}}{-32}\\\\t = \frac{-80\pm16}{-32}\\\\t = \frac{-80+16}{-32} \ \text{ or } \ t = \frac{-80-16}{-32}\\\\t = \frac{-64}{-32} \ \text{ or } \ t = \frac{-96}{-32}\\\\t = 2 \ \text{ or } \ t = 3\\\\[/tex]

Therefore, the ball's height is greater than 100 ft in the air for the interval [tex]2 < t < 3[/tex]

This is between 2 and 3 seconds, excluding both endpoints.

------------------

Check:

Let's plug in t = 2 to find that...

[tex]h(t)= -16t^2+80t+4\\\\h(2)= -16(2)^2+80(2)+4\\\\h(2)= -16(4)+80(2)+4\\\\h(2)= -64+160+4\\\\h(2)= 100\\\\[/tex]

You should find that h(3) = 100 as well. I'll let you do those steps.

Since h(2) = 100 and h(3) = 100, this confirms the two solutions we found earlier.

Answer:

8x - 4y + 12

Step-by-step explanation:

-2(-4x + 2y - 6)

(-2)(-4x) + (-2)(2y) + (-2)(-6)

(2 * 4x) - (2 * 2y) + (2 * 6)

8x - 4y + 12

The solution to the non-linear inequality 5x² + 3x < 0, in interval notation, is: (-0.6,0).

We have to look at the graph of the function relative to the x-axis, as follows:

The inequality for this problem is:

5x² + 3x < 0.

Meaning that the two bullet points above are relevant as we want to find when the function is negative.

The graph of f(x) = 5x² + 3x is given at the end of the answer, and it is negative for:

(-0.6,0).

Which is the solution set for the inequality, and is painted on the graph.
