Mrs. Peters purchased 120 flowers. The total cost was $55.20. After planting all of the flowers, Mrs. Peters decided she needed an additional 18 plants. About how much should she expect to pay total for the additional flowers.
Answer: 39.13 for 18 plants
Step-by-step explanation:
120/55.20= 2.17 dollars per plant
18*2.17=39.13

Area of rectangle OABC = 18 units²
Step-by-step explanation:
From the graph attached,
Vertices of the rectangle are O(0, 0), C(3, 0) and A(0, 6).
Length of side AO = 6 units
Length of side OC = 3 units
Area of the rectangle = Length × Width
= OC × AO
= 3 × 6
= 18 square units

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
What is product rule for differentiation?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

An amusement park collected $15,513 in revenue from ticket sales one day. They charge $30 for adults and $9 for children. If there were 865 people in attendance that day, how many were adults?
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

A ball is launched upwards from a height of 4 feet. The ball’s height as a function of time, in seconds, is modeled by the function h(t)= -16t^2+80t+4. What is the time interval in which the ball has a height greater than 100 feet?
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.
