Let <em>n </em>represent the date and <em>f(n)</em> represent the money on a specific day.
We see that the pattern is every day, we add $0.50 into our little piggy bank.
So on day 1, we get $0.50 and on day 2, we get $1.00. We can see it is a linear function and since in is increasing by $0.50, our slope <em>m </em>is $0.50.
So we get:
<em>f(n) = </em>0.5<em>n</em>
Let's test this. On day 3 we get:
<em>f(3) </em>= <em>0.5(3) </em>= 1.50
So it works! So our answer is:
<em>f(n) = 0.5n

Answer:
Now, 3x 2+x+5⩾0
This is because b² −4ac=1−4×5×3
=−59 (roots are imaginary)
3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0
2x²+7x−4=0
2x²+8x−x−4=0
2x(x+4)−1(x+4)=0
(2x−1)(x+4)=0
x= 1/2 and−4 but x≥3
∴ No solution.
lol hehehe
A matrix A is identified as
and matrix B is identified as
.If the number of columns in A is the same as the number of rows in B, then you can multiply the matrices together. The product matrix, then, is made up of what's left over: rows from A and columns from B. So your answers above are, in the first blank: columns, and in the second blank: rows.
