A model of a ship is made to a scale of 3:400

Elanso [62]

Answer:

Given:

Model : Ship = 3 : 400

The surface area of the model = 7200 cm²

To Find:

The surface area of the actual ship in m²

Let's start with the map scale given:

Model : Ship = 3 : 400

We start by adding in a unit. Usually, we choose the units associated with the model:

Model : Ship = 3 cm : 400 cm

Now, according to tot the question, we know that the actual ship is in m:

Model : Ship = 3 cm : 400 ÷ 100 m

Model : Ship = 3 cm : 4 m

The question asked for surface area, so the units have to be in squares:

Model : Ship = (3 cm)² : (4 m)

Model : Ship = 9 cm² : 16 m²

Now, that we have the units set correctly according to the question requirement, we will find 1 branch of the model:

Model : Ship = 9 cm² : 16 m²

Model : Ship = 9÷9 cm² : 16÷9 m²

Model : Ship = 1 cm² : 16/9 m²

Finally, we can find the required units by multiplying both sides with the required units:

Model : Ship = 1 cm² : 16/9 m²

Model : Ship = 1 x 7200 cm² : 16/9 x 7200 m²

Model : Ship = 7200 cm² : 12800 m²

Answer: The surface area of the ship is 12800 m²

Solve the system of equations below by graphing.

algol [13]

ANSWER

The correct answer is B

<u>EXPLANATION</u>

The first function is

$x^2-2x+y-3=0$

We make y the subject to obtain;

$y=-x^2+2x+3$

Let us quickly write this in the vertex form.

$y=-(x^2-2x)+3$

$y=-(x^2-2x+(-1)^2)+3+(-1)^2$

$y=-(x-1)^2+4$

Since the $a$ is negative, the graph opens up.

The vertex is at $(1,4)$

The y-intercept is $-3$

The x-intercept is found by equating the function to zero.

$-(x-1)^2+4=0$

$\Rightarrow (x-1)^2=4$

$\Rightarrow (x-1)=\pm 2$

$\Rightarrow x=1 \pm2$

$\Rightarrow x=-1,3$

With these information we can quickly sketch the graph as shown in the attachment(the red graph).

For the second function,

$x^2+y=0$

we again make y the subject to obtain,

$y=-x^2$

This is a basic quadratic function that can be graphed easily. Note that it is also a maximum graph.

From the graph the solution to the two functions is

$(-1.5,-2.25)$
