Answer:
Height of tree= 13.8m
Step-by-step explanation:
When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.
Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)
I have attached my working too.
I believe the shorter sides are 5 feet and the longer ones are 10. This is because when you add up the two shorter sides as 10, and the other two as 20, then add them up to 30. That's the perimeter. For the area, you would do 10•5 to get 50 for the area
Answer:
A. t=4n+950
B. h=9.5n
C. d=9.5n-(4n+950)
D. The tortoise will finish first.
Step-by-step explanation:
To find the first two equations, we put the rate at which they are traveling in front of the n, and then add where they start. Since the tortoise gets a 950 meter head start, we add 950. The hare is starting at the start line so we don't need to add anything.
For answer c, we need to subtract the two equations from each other to figure out when they would pass each other. d=(equation h)-(equation t).
For the final answer, all you need to do is plug the first two equations into a graph, and then find where each line is at the point of y 1,600. (To make the graphs I replaced the n with x and the t and h with y.) Using this, we are able to see who got there first, which was the tortoise.
He used distributive property
4^3 = 64
log4 64 = 3
The exponent always comes to the other side.
