Answer:
see below
Step-by-step explanation:
y = a ( x-0)^2 + 5 sub in the point given to calculate 'a'
1 = a (4)^2 + 5
-4 = 16a
a = - 1/4
y = -1/4 x^2 + 5
Answer:
5115
Step-by-step explanation:
We know:
a_1 = 5 the first term in the geometric sequence.
r = 2
We want Sum a_i for i = 1 to 10
a_n = 5* 2^(n-1)
Sum a_i for i = 1 to 10 = G
G = a_1* (2*2^(n-1) - 1) / (2 - 1)
G = 5 * (2^(n) - 1)/ (2 - 1), n = 10
G = 5* (2^(10) - 1)
G = 5*(1024 - 1) = 5*(1023) = 5115
All you need to do is plug 19 in for x and solve.
f(19) = 3/(19+2) - sqrt(19-3) = 1/7 - sqrt(16)= 1/7 - 4
The answer is -3.8571 or as a fraction -27/7
Answer:
c. 3 / 13
d. 2 / 13
Step-by-step explanation:
c.
A deck of cards has 52 cards. There are cards of 4 suits- Spades, Hearts, Diamonds and Clubs.
So, there are 52/4= 13 cards of each suit.
Among these 13 cards, there are 3 picture cards or face cards as they are called. These are the Jack, Queen and King cards.
So, the number of total picture cards = 4*3 = 12
the number of cards are 52
theoretical probability formula: P = favorable events/ possible events
P = 12 / 52
P = 3 / 13
d.
there are four aces and four sevens in the deck
so favorable events = 4 + 4 = 8
possible eventas = 52
P = 8 / 52
P = 2 / 13
