Answer:
The first four terms of the sequence is : A) 7, 17, 37, 77.
Step-by-step explanation:
The given function f(n) = 2 x f(n − 1) + 3
Also, f(1)= 7
<u>FOR n= 2</u>
f(2) = 2 x f(2-1) + 3 = 2 x f(1) + 3
= (2 x 7) + 3 = 14 + 3 = 17
⇒f(2) = 17
<u>FOR n= 3</u>
f(3) = 2 x f(3-1) + 3 = 2 x f(2) + 3
= (2 x 17) + 3 = 34 + 3 = 37
⇒f(3) = 37
<u>FOR n= 4</u>
f(4) = 2 x f(4-1) + 3 = 2 x f(3) + 3
= (2 x 37) + 3 = 74 + 3 = 77
⇒f(4) =77
So, the first four terms of the sequence are 7, 17, 37, 77.
A) is the correct option.
Step-by-step explanation:
f(x) = -7x² - x
g(x) = 9x² - 4x
(f - g)(x) = (-7x² - x) - (9x² - 4x)
(f - g)(x) = (-7x² - 9x²) + (-x + 4x)
(f - g)(x) = -16x² + 3x
(f - g)(1) = -16(1)² + 3(1)
(f - g)(1) = -16.1 + 3
(f - g)(1) = -16 + 3
(f - g)(1) = -13
The place value is 6 Hundred million.
Answer:
263,267
Step-by-step explanation:
473/2 is 263.5 and so just add .5 to one and subtract .5 from the other
