Answer:

23.

Using Thales theorem, we have:

AP/BP = AQ/CQ

=> 8/40 = x/45

=> x = (45 · 8)/40 = 9

24.

Also using Thales theorem, we have:

5/6 = (x - 1)/12

x - 1 = (12 · 5)/6 = 60/6 = 10

x = 10 + 1 = 11

25.

Because we already have the bisector, we know that:

x/6.9 = 18.3/6.2

x = (6.9 · 18.3)/6.2 ≈ 20.4

Hopefully all of them are correct

Need help with two math questions:

Alecsey [184]

Answers: 1:B, 2:450

How-To:

Using the formula for area on the bottom of the can, (pi*r^2) you can then multiply by the amount of height missing, which is 4.

Since it was originally 10, you subtract 4 in order to get 6.

That's how to get 4.

Now, plug in pi*r^2 into a calculator (or if you must work it out, radius, r, is 10, so 10*10 is 100. 100*3.14159265 is 314.159265

Now multiply 314 by the height missing (4) to get approximately 1257.

Now for number 2.
It says it is dilated by a scale factor of 1:3 (from 1350). That means that it was made smaller, (that's what dilated means) by 3 for every 1. So take 1350 and divide it by 3 to get 450

Use the graph to find the factorization of x2 - 5x + 4.

Oksanka [162]

Answer: B. (x - 1) (x - 4)

Concept:

Here, we need to know the idea of zeros.

The zeros of a quadratic equation are the points where the graph of the quadratic equation crosses the x-axis.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

By definition, the factored form of quadratic equations is basically their zeros.

<u>STEP ONE: Find the zeros / x-intercept of the graph</u>

The grid number is 2 per grid as 5 grids are 10 units.

The first intercept is between the y-axis and the first grid.

2 / 2 = 1

The second intercept is on the second grid.

2 × 2 = 4

<u>STEP TWO: Plug the zeros into factorization form</u>

Factor form = (x - x₁) (x - x₂)

x₁ = (1, 0)

x₂ = (4, 0)

Factorization of x² - 5x + 4 = (x - 1) (x - 4)

Hope this helps!! :)
