If you use the 'Power of 10' rule for conversions, then the conversion factor for Gigameters is 10^9. So, if you plug 10^9 into your equation needed to convert whatever amount of the two substances you have, this should help you find the answer.
Answer:
9x-27
Step-by-step explanation:
4(x-3)+5(x-3)=4x-12+5x-15=4x+5x-12-15=9x-27
Answer:
6in²
Step-by-step explanation:
Given that :
Base of right angle triangle = 3
Height of right angle triangle = 4
Area of a triangle = 1/2 * base * height
Area of triangle = 1/2 * 4 * 3
Area of triangle = 2 * 3
Area of triangle = 6in²
Answer:
<em>Correct answer: C. (1,∞)</em>
Step-by-step explanation:
<u>First Derivative</u>
Given a real continuous function f(x), the first derivative f'(x) represents the slope of the tangent line for any value of x.
If the slope of the line is positive, then the function is increasing, if the slope of the line is negative, the function is decreasing.
The function to analyze is:
Computing the first derivative:
The function will be increasing when:
Dividing by 2:
Solving:
x > 1
This solution is represented by the interval (1,∞)
Correct answer: C. (1,∞)
Here's the first equation:
w = l - 7
Knowing this:
l*w = 98
Input w:
l*(l - 7) = 98
l^2 - 7l - 98 = 0
Factor:
(l-14)(l+7) = 0
Length can't be a negative number, -7 is rejected
The length is 14, the width is 7
