The domain of f(x) = 8x^2 - 5x + 2 is all real numbers.
For the range, f(x) = 8x^2 - 5x + 2 written in vertex form is f(x) = 8(x^2 - 5/8x + 1/4) = 8(x^2 - 5/8 + 25/256 + 1/4 - 25/256) = 8(x - 5/16)^2 + 8(39/256) = 8(x - 5/16)^2 + 39/32
The range is all real numbers greater than or equal to 39/32
Answer:
3.2t - 2.4
Step-by-step explanation:
- 3.6 - 1.9t + 1.2 + 5.1t ← collect like terms
= (- 1.9 + 5.1)t + (- 3.6 + 1.2)
= 3.2t + (- 2.4)
= 3.2t - 2.4
<span>a. will have no solutions because the lines have the same slope, lines with the same slope will never intersect. b. will also have no solutions because the slopes of the two lines are the same as well, lines with equal slopes will not intersect, therefore will have no solution.</span>
81,85,89 are the missing numbers
Answer:
x = 60.5°
Step-by-step explanation:
We use the exterior angle theorem to solve this
90 + 31 = 121
121/2 = 60.5
Thus, our answer is 60.5°
