The answer for x should be 12
Answer:
remainder = 2
Step-by-step explanation:
A polynomial f(x) is divided by (x - a) then the remainder is f(a)
Here f(x) = 4x³ - 5x² + 2x - 14 is divided by (x - 2) then remainder is f(2)
f(2) = 4(2)³ - 5(2)² + 2(2) - 14
= 4(8) - 5(4) + 4 - 14
= 32 - 20 - 10
= 12 - 10
= 2
Answer:
y = 4·4^x
Step-by-step explanation:
We can write the exponential function in the form ...
y = a·b^x
The y-value for x=0 is 4, so that is the multiplier 'a' in our equation.
The ratio of values between x=1 and x=0 is 16/4 = 4, so that is the value of 'b' in the equation. The equation is ...
y = 4·4^x
_____
<em>Additional comment</em>
This could also be written ...
y = 4^(x+1)
__
Consider the values for x=0 and x=1.
x=0: y = a·b^0 = a
x=1: y = a·b^1 = ab
Then the ratio of values is (ab)/(a) = b.
This is the fact that we used in the above working.
Answer: 6
Step-by-step explanation: [▲x4]+[6x3]=6[4+3
6[4+3=42 so if [6x3]=18 then [▲x4] needs to be 24 (24+18=42) ▲=6 as 6x4=24+18=42 (6[4+3)!
