what are the value of x in the equation x^2+4-1 =0
Answers
Answer:
x = ±sqrt(3) i
Step-by-step explanation:
x^2+4-1 =0
Combine like terms
x^2 +3 = 0
Subtract 3 from each side
x^2 +3-3 = 0-3
x^2 = -3
Take the square root of each side
sqrt(x^2) = sqrt(-3)
x = ±sqrt(3) sqrt(-1)
x = ±sqrt(3) i
Find the value of x.

Mrs. Chin paid a 20 percent tip on the bill for lunch. Percents Total 20% 20% 20% 20% 20% 100% $2.75 $2.75 $2.75 $2.75 $2.75 If the tip amount was $2.75, what was the bill for lunch before the tip was added to it?
Answers
Answer: $13.75
Step-by-step explanation:
Since Mrs. Chin paid a 20 percent tip on the bill for lunch and the tip amount was $2.75, then the bill for lunch before the tip was added to it will be calculated thus:
Let the bill for lunch be represented by x. Therefore,
20% of x = $2.75
20/100 × x = $2.75
0.2 × x = $2.75
0.2x = $2.75
x = $2.75/0.2
x = $13.75
Therefore, the bill is $13.75 before the too was added.

A Group of students is tracking a friend, John, who is riding a Ferris
wheel. They know that John reaches the Maximum height of 11 m at
10 seconds and then reaches the minimum height of 1 m at 55 seconds.
What is the amplitude of the function and what does it represent in this situation?
Answers
Answer:
Part A
5 m
Part B
The maximum displacement of the Ferris wheel from the midline
Step-by-step explanation:
Part A
The amplitude is the largest displacement of a body, moving in an oscillatory, or vibrational motion from its position of equilibrium or central position about which the body vibrates
In the Ferris wheel, the central position is the midline, between the maximum height and the minimum height
Therefore, the amplitude is the maximum displacement from the midline = The maximum height - ((The maximum height - The minimum height)/2 + The minimum height)
∴ The amplitude = 11 m - ((11 m - 1 m)/2) + 1 m) = 5 m
Part B
The amplitude represents the maximum and minimum distances the Ferris wheel moves above the midline.

The formula for finding area is [tex]\pi[/tex]r2, and since half of diameter is radius, we'll need to divide the diameters given by 2. So the formula will be A = π (d/2)2.
Answer:
13π
Step-by-step explanation:
A(Circle) = πr²
r = d/2
A(Large) = π(7)² = 49π
A(Medium) = π(6)² = 36π
Therefore, the area of a large pizza is 13π greater than the area of a medium pizza.

Answers
Answer:
4x -51
Step-by-step explanation:
m(x) = 4x - 11
n(x) = x - 10

Helen scores 10 points.
Step-by-step explanation:
We are given that for every 3 points Glenn scores, Helen scores 5 points. Glenn now scores 6 points and Helen's score is unknown. We can write this as a ratio.
Glenn - 3 : 5 - Helen
Glenn - 6 : ? - Helen
We can divide 6 by 3 to get the rate of change, which is 2. Then multiply 5 and 2 and we get 10! Helen scores 10 points for every 6 points Glenn scores. I hope this helps! :D
