Answer:
2.06
Step-by-step explanation:
3x102=306
6×105=630
630 ÷ 306 = 2.0588235294
round it to 2.06
Answer:
f(-2)=4(-2)+1= 7
Step-by-step explanation:
Answer:
see work attached and shown
Given:
Height of right triangle = 9 mi
Hypotenuse = 17.5 mi
Base of right triangle = Distance across lake
To find:
The distance across the lake.
Solution:
Using Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.


Subtract 81 from both sides.


Taking square root on both sides.
⇒ base = 15
The distance across the lake 15 mi.
