Hi there!
Begin by differentiating f(x) using the power rule:
dy/dx = nxⁿ⁻¹
Therefore:
f(x) = 3x² - 5x + 10
f'(x) = 6x - 5
Set this equation equal to 0 to find the x-intercept:
0 = 6x - 5
5 = 6x
x = 5/6, which is where the graph goes from NEGATIVE to POSITIVE, so there is a MINIMUM at this value.
The three little lines through the sides of the triangle mean all three sides are equal. Because all three sides are equal the three inside angles would aso be equal.
The three angles of a triangle need to equal 180, so we can divide 180 by 3 to find what each angle is:
180 / 3 = 60.
Now we can set the equation with x in it to equal 60:
7x +4 = 60
Subtract 4 from each side:
7x = 56
Divide each side by 7:
x = 56 / 7
x = 8
Answer:
negative multiples of 3 less than -3
Step-by-step explanation:
if m <9, then
m ={8,7,6,5,4,3,2,1,0,-1,-2,....,..........}
And |6m-55|
So is said that,
when, m= 8
6(8)-55=-6
when, m=7
6(7)-54=-12
when, m = 6
6(6)-54=-18
Since the trend is negative multiples of 3 less than -3
this is my answer
The subtraction sign in front of the second set of parenthesis changes the signs on the terms inside those parenthesis. So this could be rewritten as
. None of the exponents on the x are the same, so we will just express it in terms of descending powers of x.
. This is also the same as
if you don't like to start with a negative. Either one is correct.
Answer:2 hours 15 mins = 2 1/4 hours
2 1/4 hours = 25 miles
1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles
Answer: 11.1 mph
