We have been given that the speed of elephants is 5km/h east and his speed is 41km/h west.
We have to find after how long will he be 13km from the herd.
Since the biologist is going to the west and the elephants towards east, their relative speed will be calculated by adding their respective speeds.
So final their relative speed will be:
= 5 km/h + 41 km/h
= 46 km/h
Now we want their distance to be 13 km and we have calculated relative speed as 46 km/h.
So using formula :
Speed = Distance / Time,
We calculate time as :
= Distance / Speed
= 13 / 46
= 0.28 hours
= 16.8 minutes.
So after 16.8 minutes, biologist will be 13 km away from the herd.
Step-by-step explanation:
The Ratio is given as 100:1
Which means In 1 minute you travelled 100 steps
Therefore,
- In 2 minutes you will travel = 2×100 = 200 steps
- In 3 minutes you will travel = 3×100 = 300 steps
- In 4 minutes you will travel = 4×100 = 400 steps
Answer:
9
Step-by-step explanation:
the line hits the y-axis at the point (0, 9) where x=0 meaning this point is the y-intercept being 9
Answer:
310
Step-by-step explanation:
Part A: We know that the equation for finding the area of a triangle is

; we also know that

and

, so the only thing we need to do is replacing those values into our Area equation and solve for x:




Now the only thing left is factor the quadratic polynomial:

W can conclude that the area of our triangle is
Part B: Our polynomial has three terms, so is a trinomial; also, our polynoal only has one variable,

, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a
trinomial of degree 2. Part C: Part A demonstrate the closure property of polynomials because after multiplying tow polynomials we obtained another polynomial.
