Answer:
The answer is (D) ⇒ 2x² - 2 ; domain: all real numbers
Step-by-step explanation:
∵ f(x) = 2x² + x - 3
∵ g(x) = x - 1
∴ (f - g)(x) = 2x² + x - 3 - (x - 1) = 2x² + x - 3 - x + 1
= 2x² - 2
∵ There is no value of x make the function undefined
∴ The domain is all real numbers
If the dimensions are doubled, the new pyramid is 8 times the original volume.
Find it by the formula v1=(1/3)*a*b*h
and when the dimensions are doubled, it will be v2=(1/3)*(2a)*(2b)*(2h)
By simplifying this we get: v2=(1/3)*{8}*abh
So, the new volume is 8 times more than original.
Answer:
(4 x 80) x 2 = 640 m²
(4 x70) x 2 = 560 m²
Total : 1,200 m²

<h2>MISSING NUMBER</h2>
Given:
Choices:
- a. percent
- b. rate
- c. base
- d. percentage
Answer:
- The <u>rate</u> is the missing term. Thus, option <u>b. rate</u> is the best answer.
Solving:
Rate =
Base = 50
Percentage = 25
Just convert the number into a percent since rate is the missing term. Always remember that rate have a percent sign (%).
