General equation of parabola: y-k = a(x-h)^2
Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2
All we have to do now is to find the value of the coefficient a.
(1,2) is on the curve. Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.
The equation of this parabola is y = 2x^2.
Answer:
3.25 × 10^6
Step-by-step explanation:
7.57×10^6 - 4.32 × 10^6
(7.57 - 4.32) × 10^6
<u>3.25 × 10^6</u>
Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
- Total Surface Area = 6a²
- Volume = a³
_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,
But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³
Answer:
Perimeter: 18.5
Area: 15
Step-by-step explanation:
P = a + b + c
P = 5 + 6 + 7.5
P= 18.5
A = 1/2bh
A = 1/2*7.5*4
A= 15
Answer:
Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.
First, input is the x. Looking at the graph.
Input : 0, 10, 20
Second, output is the y. Looking at the graph.
Output : 20, 30, 40
Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.
Y-intercept (b) : 20
Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.
Slope (m) : 1/2
Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.
Equation : y = 1/2x + 20
I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!
