Find the solution set of x: x^2-7x= - 10.
Answer:
(x − 2)(x −5)
Step-by-step explanation:
x² - 7x = - 10
x² - 7x + 10 = 0
Find two numbers that when added together make −7 , and when multiplied make - 10.
The numbers − 2 and −5 fit the criteria.
x2− 7x + 10 = (x − 2)(x −5)
Answer:
c = 11/4
Step-by-step explanation:
One way of doing this is to let 2c = x. Then our equation becomes
2x + x = 2x + 11/2, or x = 11/2.
But 11/2 = 2c. Thus, c = 11/4
Answer:
33.33%
Step-by-step explanation:
Carbohydrates = 4k
Protein = 3k
Fat = 2k
Total = 9k
% of protein = (3k)/(9k)*100% = 33.33%
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516 (5 if rounded)
