Draw a line straight down the middle of the triangle.
Answer:
4x + 10
Step-by-step explanation:
Given
Let
So:
--- first 2 hours
--- last 3 hours
Required
Distance covered in the first 2 hours
Distance (d) is calculated as:
i.e.
For the first 2 hours, we have:
So:
Open bracket
<em>Hence, the distance covered in 4x + 10</em>
Answer:
See below in bold.
Step-by-step explanation:
Factored form:
f(x) = -5(x + 7)(x - 9)
Standard form:
f(x) = -5(x^2 + 7x - 9x - 63)
f(x) = -5(x^2 - 2x - 63)
f(x) = -5x^2 + 10x + 315.
Answer: speed = 17m/s
time taken = 3min = 3 x 60 = 180 seconds (1min = 60sec)
distance = ST
= speed x time
= 17 x 180
= 3060m
