A function is described by the equation f(x) = 2x + 3. The replacement set for the independent variable is (2,4,6,8). Which set
Anna11 [10]
<h3>Answer:  {7, 11, 15, 19}</h3>

Write the values in the order shown. The curly braces indicate a set.

=================================================

Explanation:

The replacement set for the independent variable is {2,4,6,8}

This means we'll plug x = 2, x = 4, x = 6, and x = 8 into the function one at a time to find the corresponding y = f(x) value.

---------

Plug in x = 2 to find that,

f(x) = 2x+3

f(2) = 2*2+3 ... replace every x with 2

f(2) = 4+3

f(2) = 7

If the input is x = 2, then the output is y = 7. Therefore, the '2' in the domain corresponds to '7' in the range.

If you repeat those steps for x = 4, then you should find that f(4) = 11. Do the same thing for x = 6 and it should lead to y = 15. The last value in the range is y = 19 which corresponds to x = 8.

In short, the domain {2,4,6,8} corresponds to the range {7, 11, 15, 19}

Usually with sets, order doesn't matter. However, in this case, the order is important because we need to match the 2 with the 7, the 4 with the 11, etc.

A fishing boat with two people on it runs out of gas while out in a bay. The people set off an emergency flare from a height of
elixir [45]

Answer:

Step-by-step explanation:

time taken to reach the max height is expressed according to the projectile equation;

tmax = u/g

Given u = 30m/s

g is the acceleration due to gravity = 9.81

t = 30/9.81

t = 3.0secs

hence it will take the flare 3.06secs to reach its maximum height.

Max height = u²/2g

Max height = 30²/2(9.81)

Max height = 900/19.62

Max height = 45.87m

If the people set off an emergency flare from a height of 2 meters above the water, the total height will be 45.87 + 2 = 47.87m

Andrew, Brenda and Cammi all work part-time at a supermarket. Cammi earns $20 more than Andrew
stellarik [79]

Step-by-step explanation:

Let Andrew wage be = X

Cammi earns $20 more than Andrew So Cammi earns = 20 + X

Brenda earns $30 less than twice Andrew's wage

So she earns = 2X - 30

Their total combanied wage is $400

So Andrew + Cammi + Brenda = $400

X + 20+X + 2X-30 =400

4X - 10 =400

4X=400+10

4X=410

X= $102.5

So Andrew earns $102.5

Cammi earns $122.5

Brenda earns $175
