F(x) is continuous for all x.
Pick a point and show that f(x) is either negative or positive. Pick another point and show that f(x) is negative, if positive, or positive, if negative.
At x = 30, f(30) - 1000 = 900 + 10sin(30) - 1000 ≤ 0
Now, show at another point f(x) - 1000 is positive, and hence, there would be root between 30 and such point.
Let's pick 40.
At x = 40, f(40) - 1000 = 1600 + 10sin(40) - 1000 ≥ 0
Since f(x) - 1000 is continuous, there lies a root between 30 and 40, and hence, 30 ≤ c ≤ 40
False.
Right triangles do not have to be congruent.

Answer:
we can make 5 servings of spice rub from 10 table spoons of onion powder
Step-by-step explanation:
Given the data in the question;
2 table spoon of onion powder makes one serving of spice rub.
Total table spoons of onion powder available = 10
So Let x represent the number of servings of spice rub we can make from our 10 table spoons of onion powder ;
2 table spoons = 1 servings
10 table spoons = x servings
we cross multiply;
x servings × 2 table spoons = 10 table spoons × 1 servings
x servings = ( 10 table spoons × 1 servings ) / 2 table spoons
x = 10 / 2
x = 5 servings
Therefore, we can make 5 servings of spice rub from 10 table spoons of onion powder
Answer: y = 
<u>Step-by-step explanation:</u>
y = ax² ; where a represents the vertical stretch
a reflection across the x-axis is represented by making the a-value negative.
