A² + b² = c²
a = 2b, c = 10
(2b)² + b² = 10²
4b² + b² =100
5b² = 100
b² = 100 ÷ 5
b² = 20
Answer: 20
Answer:
No
Step-by-step explanation:
He is not correct because paper is a one-denominational surface, and volume only comes from 3 denominational objects.
To find this, turn the word question into an equation.
"One less than" means - 1, which is 1 being subtracted from something.
"half a number" means 1/2x, since 1/2 is half and x is unknown.
"is 12" means = 12, which is something equals 12.
Putting this in order would be 1/2x, then - 1, then = 12.
As an equation, this is 1/2x - 1 = 12.
So the equation is 1/2x - 1 = 12
Now you must find the number by solving this equation.
1/2x - 1 = 12
First, add 1 to both sides.
12 + 1 = 13
1/2x = 13
Now multiply both sides by 2.
This way, x will be isolated since 1/2x • 2 = 1x, and 1x = x.
13 • 2 = 26
x = 26
The number is 26.
First and foremost is the vertex, which is either the highest point or the lowest point of the parabola (which’s is what the graph of a polynomial looks like). From the vertex, you can always determine the next two points closest to the maximum/minimum.
Another key feature includes the y-intercepts, which are important if you want to find the zeros of the polynomial. Sometimes, the x-intercepts may come in handy as well, but not as often as the y-intercepts.
