Answer:

y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)

Step-by-step explanation:

There are 4 x-intercepts: -3, -2, 1, 3

So y(x) = C(x+3)(x+2)(x-1)(x-3)

At x = 0, y-intercept is -1

so -1 = C*3*2*(-1)*(-3) = 18C,

C = -1/18

Then y(x) = (-1/18)(x+3)(x+2)(x-1)(x-3)

A circle has a radius of 6 feet. Calculate the area of the<br> sector formed by a central 30° angle

Tems11 [23]

Answer:

The area of the sector is 9.43 ft^2

Step-by-step explanation:

Here, we want to find the area of the sector with a central angle of 30 degrees

To do this, we use the formula below;

Area of sector = theta/360 * pi * r^2

theta = central angle = 30 degrees

r = radius = 6 ft

Thus, we have it that;

Area of sector = 30/360 * pi * 6^2

= 30/10 * pi = 3 * 3.142 = 9.43 ft^2

If the hypothesis is false, an argument cannot be valid, how would you explain this?

Elodia [21]

If the hypothesis was wrong, all you simply have to do is state the hypothesis was wrong and why you think it was, and add what you can do to change it or to make it better so next time it will be right. Just state what you did and how you got your answer.

I hope that helps!

Could someone please explain/help me to do this using Pythagoras theorem?

alex41 [277]

Answer:

$\boxed{478.02}$

Step-by-step explanation:

→ First understand what Pythagoras theorem is

Pythagoras is a theorem used to find the hypotenuse (the side opposite to the right-angle) of a triangle. We would need the base lengths as well the height in order to use Pythagoras.

→ State the formula and identify the letters

a² + b² = c² ⇒ where 'a' is 380cm, 'b' is 290cm and 'c' is what we are trying to work out

→ Substitute in the values into the formula

380² + 290² = c²

⇒ Simplify

144400 + 84100 = c²

⇒ Collect the numbers together

228500 = c²

⇒ Square root both sides to find 'c'

478.0167361 = c

→ The length of the diagonal is 478.02
