In short, for a vertical parabola, namely one whose independent variable is on the x-axis, usually is x², if the leading term coefficient is negative, the parabola opens downward, and its peak or vertex is at a maximum, check the picture below at the left-hand-side.
and when the leading term coefficient is positive, the parabola opens upwards, with a minimum, check the picture below at the right-hand-side.
Answer:
area = 100.5 in²
Step-by-step explanation:
area = 13.4 x 7.5 = 100.5 in²
The answer is 700 meters
why?
1. km=1000.m so when you move the 1 to the right .1 you have to do the same woth 1000. which will be 100.0
the answer is 20
why?
1 quart=4 cup so change 1 to 5 which means *5 and the same with cups 4 to 20 which means *20
Answer:
-0.53, 2.53 to the nearest hundredth.
Step-by-step explanation:
3x^2 - 6x - 4 = 0
3(x^2 - 2) - 4 = 0
3 [ ( x - 1)^2 - 1] = 4
3(x - 1)^2 - 3 = 4
3(x - 1)^2 = 7
(x - 1)^1 = 7/3
x - 1 = +/- √(7/3)
x = +/- √(7/3) + 1
x = 2.53, -0.53.
Answer:
x=4.225
Step-by-step explanation:
You can use your trigonometric ratios to help you solve this problem. We have the hypotenuse and the angle that the triangle makes with the adjacent side. X is the adjacent side of this problem, therefore we need to take the cosine of this angle (remember SOHCATOA, Sine: Opposite/Hyp, Cosine: Adjacent/Hyp, and Tan: Opp/Adj) using this, we can model an equation where Cos(62)=(x/9), in order to solve for x, simply multiply both sides by 9 to get a final answer of 4.225...
