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
The period of her heartbeat cycle is 3/4 seconds.

(d) a graph is attached.
When you divide exponents, you just subtract them. the answer to this equation is a^2 (a squared). This is because 8-6 = 2. Conversely, if you were multiplying two terms with exponents you would add the exponents together. For example: a^3 * a^2 = a^5, because 3 + 2 = 5

The answer is A: 5
The y-intercept is when x = 0
<span>3y + 4x = 15
x = 0
3y + 4 * 0 = 15
3y + 0 = 15
3y = 15
y = 15/3
y = 5</span>
