Expression: 80+15x=y
(x means months)
so at the end of the year jason will have $260
Distance covered = 2 km
time taken = 30 minutes = 0.5 hour
speed = distance/time = 2/0.5 = 4 km/h
<h3><u>Answer</u><u>:</u></h3>
<h3><u>S</u><u>olution</u><u>:</u></h3>
In the given right angled triangle, we have :
- Base ( BC ) = 5
- Hypotenuse ( AB ) = 6
- Perpendicular ( AC ) = ?
<u>Using </u><u>Pythagoras </u><u>theorem</u><u>:</u>
➙ H ² = B² + P ²
➙ AB² = BC² + AC²
➙ 6² = 5² + AC²
➙ AC² = 6² - 5²
➙ AC² = 36 - 25
➙ AC² = 11
➙ AC = √ 11
<u>➙ AC = 3.32</u>
<u>➲</u><u> </u><u>M</u><u>o</u><u>r</u><u>e</u><u> </u><u>information</u><u>:</u>
- According to Pythagoras theorem,In a right angled triangle, the square of the Hypotenuse is equal to the sum of square of base and Perpendicular.
Slope= (-4-2)/(1-(-1)) = -6/2=-3 so the only answer choice with the slope as -3 is A, and that is your answer
