Doctors treated a patient at an emergency room from 2:00 P. M. to 7:00 P. M. The patient's blood oxygen level L (in percent) during this time period can be modeled by L = −0.270t² + 3.57t + 80.6 2 ≤ t ≤ 7
where t represents the time of day, with t = 2 corresponding to 2:00 P. M.
Use the model to estimate the time (rounded to the nearest hour) when the patient's blood oxygen level was 92%.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
