Answer:
I only
Step-by-step explanation:
given h = - at² + bt + c
the vertex = - 
Thus altering a or b effects the position of the vertex
and the maximum value is the value of the vertex
Altering c effects the h-intercept only
Answer:
I believe the answer to be 387.11
Step-by-step explanation:
A=1/4√5(5+2√5) a°2=1/4√5•(5+2•√5)•15°2=387.10742 cm°2
Rounded= 387.11
One third is one of those rational numbers that can never be
exactly written as a decimal. To change a fraction into its
decimal, you divide the top number by the bottom number,
and the quotient is the decimal form of the fraction.
When you divide 1 by 3 , you get .333... and the 3s never
stop. They just keep going on forever.
That's called a "repeating" decimal.
Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.
