Hi there!
For the Pythagorean Theorem, basically you just need to apply this formula: a^2 + b^2 = c^2
And then find the root of the hypotenuse.
For example,
15^2 + 8^2 = the hypotenuse^2
Which equals, 225 + 64 = 289
Square root of 289 = 17
Please mark me brainliest if this helps!
Have a wonderful day!
To answer the question above, determine the velocity of the car at time zero. To do such, determine the increase in velocity every hour (acceleration).
a = (62 - 53) / (6 -3) = 3 km/ h^2
Calculate for the initial velocity (v) by using either of the velocities paired with the corresponding time,
v = 53 km/h - (3 km/h^2) x 3 h = 44 km/h
The equation is <em>y = 44 + 3x</em>. Where x is the time in hours, y is the velocity in km/h.
3 ( 3x + 6 + x ) = 1
Step 1, apply distributive method.
9x + 18 + 3x = 1
Step 2, simplify the following
12x + 18 = 1
Step 3, Change side
12x = -17
Final answer
x = -17/12
<em>The </em><u><em>error/mistake was in step 2</em></u><em> where [ 9x +3x = 12x ]</em>
<em />
<u><em>Recheck the answer</em></u>
3 ( 3x + 6 + x ) = 1
3 ( 3(-17/12) + 6 + -17/12 ) = 1
1 = 1
Hence proved our solution is correct.
Your answer should be xy.
