Answer:A:√7+√3+√98−√18 Part B:3√5−3√11+2√121−3√90. 1.
Step-by-step explanation:
Use the substitution method
f(x)= 3-2x
f(4)= 3-2(4)
Do multiply first then subtract
= 3-8
= -5
Answer : f(4)= -5
Answer:
24
Step-by-step explanation:
mode means most so 24 is written twice and the others only once.
you're welcome if I helped. :/ (not sure if I helped)
The temperature that accurately describes the time that would have spent cooling is 300.
<h3>How to solve for the cooling time.</h3>
We have the function as f(t) = 349.2(0.98)t
We have to solve for all of the values in the option
When t = 0
This would give us an infinite value for t hence it is not the answer.
When t = 100
we have 61.6
When t = 300
we have f(t) = 7.5
WHen t = 400
f(t) = -6.7
From the solved values the accurate one that has to talk about the time spent cooling is 300 at 7.5
<h3>Complete question</h3>
The function f(t) = 349.2(0.98)t models the relationship between t, the time an oven spends cooling and the temperature of the oven. For which temperature will the model most accurately predict the time spent cooling? 0 100 300 400

Did your explanation include the following?
Some polynomial equations have complex solutions.
Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane.
Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.
