Answer:
10.24 in²
Step-by-step explanation:
First we need to know how to find the area of a rectangle, which is base * height.
We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.
To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.
We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!
7/11
you do rise over run, which is y2-y1/x2-x1
The answer is B, or y - 6 = 3/4 (x - 4). To put (-4, 6); m = 3/4 in point-slope form, you first start with the point-slope form equation which is y - k = m (x - h). The ordered pair that it wants you to put in is (-4, 6). To figure out where the ordered pair goes, you replace the variables (h, k) with (-4, 6). The h will always be the point on the
x-axis and the k will always will be the point on the y-axis. Putting these together, you now get y - 6 = m (x - 4). As the same in slope-intercept form, or y=mx+b form, the slope in this equation is m. In this equation, m = 3/4. So, the equation in point-slope form is y - 6 = 3/4 (x - 4).
