Answer:
undefined slope, it's a vertical line
A vertical line on a sheet of lined graph paper is a vertical axis (normally called the X axis) that denotes everything to the left of the line is negative and everything to the right is positive. A horizontal line on that graph paper (normally called the Y axis) denotes everything below the line is negative and every thing above is positive. Each axis is graduated in scale. The equation X=Y has no single answer, but we can plot a locus of points on your graph by assigning values to X ( or Y) and create a diagonal line which passes thru the origin (where the lines cross) that denotes all possible answers to the equation that exist within the limits of the graph paper. Every equation will plot a locus of points.
The area of a pyramid is the sum of area of the base and the area of slant triangles.
The area of the base is 1.5 × 1.5 = 2.25 cm²
The slant height of each triangle, s is 3 cm
The area of the triangles = 1/2 × 1.5 × 3 × 4
= 9 cm²
Therefore, the area of the pyramid
=9 +2.25
= 11.25 cm²
The formula for simple interest is:
Total = Principal(1+ Rate x time)
You are given:
Total = $100
Principal = $20
Rate = 4%
You are asked to find the time.
Replace everything known in the formula:
100 = 20(1 +0.04 x Time)
Now solve for Time:
Divide each side by 20:
5 = 1 + 0.04 x Time
Subtract 1 from each side:
4 = 0.04 x time
Divide each side by 0.04:
Time = 4 / 0.04
Time = 100 years.
