hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t = 
and t = -
However, as time cannot rewind, we will keep only positive solution
So t =
in seconds it will be : 3.3 seconds
Answer:
1 Superscript 13 and 1 Superscript 15
Step-by-step explanation:
The process of exponentiation can be mathematically written as:
a^b
where a is called the base, and b is called the exponent.
Basically it means that we have to multiply the base with itself as many times as the value of the exponent.
For example 2^4 is 2•2•2•2
Having this in mind, 1^13 and 1^15 have equivalent values, because no matter how many times we multiply 1 with itself it will always be equal to 1.
Answer:
A
Step-by-step explanation:
Just as squared has an exponent of 2, cubed has an exponent of 3.
Therefore, k is seen as 
(or K^3 if that is too small to see)
Another keyword is "plus" as this indicates addition which has a symbol of +
So in this case, your answer would be A) K^3 + 7
There are 7 parent tigers
Parents = 7
7 tigers each have 7 children. That means there's total of 7 × 7 children.
Children = 7 × 7 = 49
Each child has 7 friends. That means there's total of 49 × 7 friends.
Friends = 49 × 7 = 343
Total = 7 + 49 +343 = 399 TIGERS
I'm not a tiger so I'm not counting myself.
