Answer:
Step-by-step explanation:
So the equation used to find the axis of symmetry in a quadratic function is
x = -b / 2a
So our b term is = 3
and our a term is = 2
So:
-3 / 2(2)
or
x = -3 / 4
Answer:
x=3 & x=-2/3
Step-by-step explanation:
- 3x^3+2x^2-27x-18
- (3x^3-27x)+(2x^2-18)
- 3x(x^2-9)+2(x^2-9)
- (3x+2)(x^2-9)
- 3x+2=0
- 3x=-2
- 3x/3=-2/3
- x=-2/3
- x^2-9=0
- x^2=9
- =
- x=3
- x= -2/3 & x=3
The answer is 42 degrees.
A triangle has to equal 180 degrees in total. Because you know it is a right triangle and b is the right angle you make angle a plus c equal 90. You add together 8x and 9x to get 17x and add the 2 and 3 to get 5. You have to solve for x so you subtract 5 from both sides to get 17x = 85. To get x alone you divide both sides by 17 giving you x=5. Now that you have x you plug it into to the equation for angle a. This gives you 8(5)+2 which equals 42.
8x+2+9x+3=90
17x+5=90
17x=85
X=5
8(5)+2=
40+2=42
Area = 16 × 21 × 1/2
= 168 m
your answer was right !!! keep on practice
Answer:
The limit leads to a determinate form.
Step-by-step explanation:
The following are indeterminate forms.
Given the limit of a function , to show if the given limit is determinate or indeterminate form, we will need to substitute the value of - into the function as shown,
where a is any constant, therefore
Since we are able to get a finite value i.e 0, this shows that the limit does exist and leads to a determinate form
