Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(1). 2 8 10 4

Klio2033 [76]

Hello!

You can solve this by plugging 1 into $g(x)$ and plugging the result into $h(x)$ .

$g(x) = 2x$
$g(1) = 2(1)$
$g(1) = 2$

$h(x) = 2x + 4$
$h(g(1)) = 2(2) + 4$
$h(g(1)) = 4 + 4$
$h(g(1)) = 8$

Answer:
<span>(h ∘ g)(1) = 8</span>

Show your work 2 1/5 × 3 1/8

vesna_86 [32]

Solution

For this case we can do the following:

$2\cdot\frac{1}{5}=\frac{2\cdot5+1}{5}=\frac{11}{5}$ $3\cdot\frac{1}{8}=\frac{3\cdot8+1}{8}=\frac{25}{8}$

And then if we multiply we got:

$\frac{11}{5}\cdot\frac{25}{8}=\frac{55}{8}$

Mai is filling her fish tank. Water flows into the tank at a constant rate. Complete the table and answer the question below.

Answer:

$r = 1.6$

Step-by-step explanation:

Given

x ----- y

0.5. --- 0.8

1. --- 1.6

3.--- 4.8

25. --- 40

Required

Determine the constant of proportionality

This can be calculated using the following formula:

$y = rx$ ; Where r is the constant of proportionality;

Solve for r

$r = \frac{y}{x}$

When x = 0.5; y = 0.8

$r = \frac{0.8}{0.5}$

$r = 1.6$

When x = 1; y =1.6

$r = \frac{1.6}{1}$

$r = 1.6$

When x = 3; y = 4.8

$r = \frac{4.8}{3}$

$r = 1.6$

When x = 25; y = 40

$r = \frac{40}{25}$

$r = 1.6$

Notice that the value of r is constant throughout;

Hence:

$r = 1.6$
