Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Answer:
5%
Step-by-step explanation:
Probability is the likelihood of an event taking place.
-Given there are 95 white and 5 blue pieces, the total number of papers is 100.
-The theoretical first attempt probability is equivalent to the number of each paper divided by the total:
Hence, the theoretical probability that a blind-folded person draws a blue piece of paper on the first attempt is 0.05 or 5%
The balance in dollars at the end of 4 years will be $1,462.50
Answer:
The answer to your question is: d = 0.85 units
Step-by-step explanation:
Data
Line equation: 1.2 x − 0.5 y + 1.1 = 0 A = 1.2; B = -0.5; C = 1.1
Point (0, 0) x = 0; y = 0
Formula
d = | Ax + By + C | / √(A² + B²)
Process
d = |(1.2)(0) + (-0.5)(0) + 1.1 | / √ (1.2)² + (0.5)²
d = | 1.1 | / √ 1.44 + 0.25
d = 1.1 / √ 1.69
d = 1.1 / 1.3
d = 0.85 units
