Answer:
This is very unclear however if your miles are 214 and you need 1% of the miles you can multiply it by 0.01 and the answer would be 2.14 miles
Answer:
- Identify the correct parent function.
- Is the relation also a function?
Yes, all inputs have one output.
- Is it continuous or discrete?
Continuous, it has a solid line.
- What is ?
Answer:
<u>1. 3x^2 + 4x - 5 = 0</u>
<u>x₁ = (-2 + √19)/3</u>
<u>x₂ = (-2 - √19)/3</u>
<u>2. X^2 - 13x + 42 = 0</u>
<u>x₁ = 7</u>
<u>x₂ = 6</u>
Step-by-step explanation:
1. Let's solve for x using the quadratic formula this way:
3x^2 + 4x - 5 = 0
x = [-4 +/- √(4² - 4 * 3 * -5)]/2 * 3
x = [-4 +/- √(16 + 60)]/6
x = [-4 +/- √76]/6
x = [-4 +/- 2√19]/6 (√76 =√4 * 19)
x = -2 +/- √19/3
<u>x₁ = (-2 + √19)/3</u>
<u>x₂ = (-2 - √19)/3</u>
2. Let's solve for x, factoring this way:
X^2 - 13x + 42 = 0
(x - 7) (x - 6) = 0
<u>x₁ = 7</u>
<u>x₂ = 6</u>
Answer:b
Step-by-step explanation:
19. It notes or hints to using the quadratic formula because the equation can not be solved by factoring alone. Thus you must use the quadratic formula.
A=-16 B=25 C=3
It is so hard to type a normal equation let alone one of the quadratic formula so I will just attach a picture instead.
However you will end up getting two roots/zeros/x-intercepts of -0.11 and 1.67.
However since it is an application question asking for answers only in the first quadrant you must choose the positive x-intercept.
Therefore the water balloon will land at 1.67 seconds.
20. This question is very simple as it asks you to find a height at a given time. You simply put the given time (1second) into the equation and get your answer.
h=-16(1)^2+25(1)+3
h=12
Also don't mind my little scribble there. :)
