Answer:
568
Explanation:
First you need to make an equation. You need to find the change, in this case it’s 1.25. After, you find that, you make your equation. A(n)=16(1.25)^n-1.

What is being solved for is r.




Answer:
x = 6
Step-by-step explanation:
<em>This can be written as a ratio</em>
7 : 2
21 : x
<em>If you times one side by 3, you have to multiply the other side by three too:</em>
2 × 3 = 6
∴ x = 6 when y = 21
Answer:
Step-by-step explanation:
r=√((4-1)²+(2+2)²)=√(9+16)=5
area of circle=π r²=3.14×5²=78.50=78.5
Answer:
Therefore the required point where it crosses y-axis is (0 , 4)
Step-by-step explanation:
Given:
...............Equation of line
Intercepts:
The line which intersect on x-axis and y-axis are called intercepts.
There are two intercepts:
x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.
y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.
For a line crosses Y-axis we have,
Put x = 0 in above equation we get
Therefore the required point where it crosses y-axis is (0 , 4)
