Answer:
127.3 ft
Step-by-step explanation:
A baseball diamond is constructed in a square shape.
The sides are 90 ft each
If a catcher throws a baseball to the shortstop who is half-way between second and third bases, the distance between the third base and the short stop = 1/2(90)
= 45 ft
length of the throw is found using Pythagoras theorem.
Hypothenus ^2 = opposite ^2 + adjacent ^2
= 90^2 + 45^2
Hypothenus = √8100 + 2025
=√10125
= 100.62 ft (approximately)
Answer:
y = 0.1(4^x)
Step-by-step explanation:
An exponential function can be written as ...
y = a(b^x)
where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.
The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...
y = 0.1(4^x)
Each snack cost $5.50
You start with $45, and afterwards end up with $12, so subtract 12 from 45 and you end up with 33. Then divide 33 by 6, since she bought 6 snacks, and you get $5.50.
