Answer:
Take the square root of each side
D (x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
Step-by-step explanation:
We have
(x+b/2a) ^2 = (b^2-4ac)/ 4a^2
We need to take the square root of each side to continue to isolate x
(x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
I hope thats right
Answer:
True
Step-by-step explanation:
∫₀°° f(x) dx = ∫₀¹ f(x) dx + ∫₁°° f(x) dx
We know that ∫₁°° f(x) dx converges, and we know that f(x) is continuous on [0, 1], inclusive. Therefore, ∫₀¹ f(x) dx converges, so ∫₀°° f(x) dx converges.
Answer:
V≈17974.16
Step-by-step explanation:
Using the formulas
V=4
3πr3
d=2r
Solving for V
V=1/
6πd^3=1/
6·π·32.53≈17974.16422
The slope (6.2) is her temperature change over time. the y (64) is the temperature at the start of the recording
Answer:
No real roots.
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Quadratic Formula:
<u>Algebra II</u>
Step-by-step explanation:
<u>Step 1: Define</u>
-3x² + 2x = 1
<u>Step 2: Rewrite in Standard Form</u>
- Subtract 1 on both sides: -3x² + 2x - 1 = 0
<u>Step 3: Define</u>
a = -3
b = 2
c = -1
<u>Step 4: Find roots</u>
- Substitute in variables:
- Exponents:
- Multiply:
- Subtract:
Here we see that we cannot take the square root of a negative number. We will get no real roots and only imaginary ones.
