Answer:
$113.81
Step-by-step explanation:
Find the cost for one book:
35.94 / 6 = 5.99
Multiply 5.99 with the number of books buying:
5.99 x 19 = 113.81
<u><em>Answer: -2/5+1/5i</em></u>
Explanation:
complex rule.
(-3*7+1*1)+(1*7-(-3)*1)i/7²+1² ← as the fractions
then refine and rewrite the problem down.
-20+10i/50 ← as the fractions shown.
-20+10i/50=-2+i/5
you can also rewrite the problem down in standard complex form.
-2+i/5=-2/5+1/5i
<u><em>=-2/5+1/5i</em></u>
Hope this helps!
Thanks!
Have a great day!
Answer:
It grew 0.22 ft on the average yearly
Step-by-step explanation:
Here, we want to calculate the average growth rate
We find the difference between the heights
That will be;
(14-1) = 13
divide by the number of years
= 13/58 = 0.22 meter per year
Find 2 points on the line:
We will use (2,2) and (0,-6)
Find the slope of the line which is the change in Y over the change in X:
(-6-2) / (0-2) = -8/-2 = 4
The slope = 4
Find the Y intercept:
y = 4x+b
use y1 for y and x1 for x
2 = 4(2) +b
2 = 8 +b
Subtract 8 from both side:
b = -6
Now you have the slope (4) and Y intercept (-6)
The equation of the line becomes y = 4X-6
The line is solid and the shaded portion of the graph is to the left of the line and it is a positive slope so the inequality would become
y ≥ 4x -6
Answer:
Step-by-step explanation:
The pythagorean theorem is where c is the hypotenuse.
so,
9 + 36 = 45
c =
