Answer:

Ummm i did 2a, 2b, 2c, and 3

Step-by-step explanation:

2a.

p(x)=4x - this is because the sides of a square is x, the perimeter is 4x

0->0, 1->4, 2->8, 3->12, 4->16, 5->20, 6->24

2b.

y=4x

2c.

plot the points (0,0), (1,4), (2,8), (3,12), (4,16), (5,20), and (6,24) then connect them, it should be a straight line

f(x)=80-15x, when x is 2.5 you get 80-15(2.5)=42.5

A(x)=25+10x, when x is 2.5 you get 25+10(2.5)=50

50>42.5

therefore A(x)>f(x)

P(x) = 3x + 4<br>q(x) = 2x2<br>Find q(P(x))

max2010maxim [7]

Answer:

Step-by-step explanation:

If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:

$2(3x+4)^2$ is the composition of p into q. Now all we have left to do is simplify.

$(3x+4)^2=9x^2+24x+16$

Then we have to finally multiply in the 2 to get:

$18x^2+48x+32$

future value = P × (1+ i)t `"present value" = "P" / (1 + i)^"t"` What would be the value of $100 after 10 years if you earn 11 p

vesna_86 [32]

Answer:

B) $\simeq 283.94$ (in $)

Step-by-step explanation:

Value of $100 after 10 years if I earn 11 % interest per year is given by,

$ $(100 \times (1 + \frac{11}{100})^{10})$

$\simeq 283.94$ (in $)

We know that if,

Principal= P

Rate of annual compound interest = r %

Time = n year

then amount, A = $P \times (1 + \frac{r}{100})^{n}$
