Answer: last option. 9.2
Step-by-step explanation:
The pythagoreon theorm tells us, a^2+b^2 = c^2. We can substitute these values, so 7^2 + 6^2 = x^2 => 49+36 = x^2 => root of 85. The root of 85 is 9.219 something so you can round 9.219 to 9.2.
Answer:f(0)=9
Step-by-step explanation:
g(0)=(-0)^2+9
g(0)=0+9
g(0)=9
Answer:
x + 0.05x
Step-by-step explanation:
Given
Earnings earned by the bookstore = x
percentage increase = 5%
Increment = 5% of x
Increment = 0.05x
book store's total increase in profit = Original earning + increment
book store's total increase in profit x + 0.05x
Hence the expression that represents the book store's total increase in profit is x + 0.05x
