I believe your answer is:
D)

Here’s why:
- A trinomial is a expression that consists of three terms.
- A term can be a number, variable, or both numbers and variables that are multiplied together.
- Answer choice 'D' has three terms, c², 'c', and '6'. Therefore, it is a trinomial.

Answer:
(a) 110 mm Hg
(b) 70 mm Hg
(c) 3/4 second
(d) see the attachment
Step-by-step explanation:
(a) The sine function has a maximum value of +1, so the maximum value of p is ...
pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg
__
(b) The sine function has a minimum value of -1, so the minimum value of p is ...
pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg
__
(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.
8π/3·t = 2π
t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t

Answer:
• Group the h terms by organised term arrangement :
• Then using distributive property, factorise out the value h so that the reverse is true.
• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:
• finally, completely factorise out the value h
Given:
- the discounted price was offered by the yoga studio at 50% off the regular price 'r' (monthly fee).
- the one-time processing fee is $8.25
- 10 students took this offer and the yoga studio collected $392.50
To Find:
The regular price of the monthly fee 'r'
Solution:
The equation can be framed as
And, the regular price of the monthly fee is $62.
Calculation:
We know that 10 students took the offer and the yoga studio collected $392.50. This means, using the Unitary Method, the studio has collected $(392.50/10) = $39.25 per student.
Now, if r denotes the regular price of the monthly fee, the offer runs a 50% discount on r.
So, the discounted price should be $(r - 50% of r) i.e.,
We must add to this the one time processing fee of $8.25
Therefore, the total price paid by one student would be
This must be equal to $39.25 as we have calculated this to be the amount collected by the yoga studio per person.
So, the equation can be framed as
Thus, the regular price of the monthly fee is $62.
