Answer:
no, 72 km/hr is equal to 20m per sec
Step-by-step explanation:
20 m = .02 km
.02 km per hour is equal to .02(3600) per hour, which is 72 km per hour
(you have to multiply my 3600 to get seconds into hours)

Answer:
B) 5 + 17i is your answer.
Step-by-step explanation:
In order to write this equation as a complex number in standard form, you must first simplify each term.
<em>Apple the distributive property.</em>
21 - 4i - 1 * 16 - (7i) + 28i
<em>Multiply -1 by 16.</em>
21 - 4i -16 - (7i) + 28i
<em>Multiply 7 by -1.</em>
21 - 4i - 16 - 7i + 28i
<em>Now simplify by adding terms :)</em>
<em>Subtract 16 from 21.</em>
5 - 4i - 7i + 28i
<em>Subtract 7i from -4i.</em>
5 - 11i + 28i
<em>Add -11i and 28i.</em>
= 5 + 17i
If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.
The formula of a slope:
PQ → (0, 3), (2, 0).
Substitute:
QR → (2, 0), (4, -3).
Substitute:
CORRECT :)
<h3>Answer: m = -1.5.</h3>
Answer:
The smallest value of the three numbers would be 9.
Step-by-step explanation:
In order to find this, set the smallest number as x. Then you can set each of the next integers as x + 1 and x + 2. Now we can total all three numbers and set equal to 30 to solve for x.
x + x + 1 + x + 2 = 30
3x + 3 = 30
3x = 27
x = 9
