What is the factored form of the polynomial? z2 − 10z + 25

Mathematics
1 answer:
Crank3 years ago
5 0

Answer:

(z−5)(z−5)

Step-by-step explanation:

Let's factor z2−10z+25

z2−10z+25

The middle number is -10 and the last number is 25.

Factoring means we want something like

(z+_)(z+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -10

Multiply together to get 25

Can you think of the two numbers?

Try -5 and -5:

-5+-5 = -10

-5*-5 = 25

Fill in the blanks in

(z+_)(z+_)

with -5 and -5 to get...

(z-5)(z-5)

The axis of symmetry is X=-2

The vertex is (-2,4)

The maximum is 4

There is no minimum as the maximum is also the vertex of the parabola.

The zeros are (-4,0) and (0,0) or just 0 and -4

The domain is all real numbers from negative infinity to positive infinity

The range contains all real numbers less than or equal to 4 :)

A truck with 20 inch diameter wheels is traveling at 45mi/hr
Harrizon [31]

A wheel with a 20 in diameter has a circumference of 2π*(20 in) = 40π in.

For every 40π in traveled, a wheel makes one complete revolution, or turns an angle of 2π rad.

We need to convert from in to mi: there are 12 in to 1 ft, and 5280 ft to 1 mi, and so there are 12*5280 = 63,360 in to 1 mi.

We also need to convert h to min: there are 60 min to 1 h.

So we have an angular speed of

(45 mi/h) * ((2π)/(40π) rad/in) * (63,360 in/mi) * (1/60 h/min) = 2376 rad/min

As mentioned before, there are 2π rad to 1 rev, so

(2376 rad/min) * (1/(2π) rev/rad) ≈ 378.152 rev/min

(where rev/min is equivalent to rpm)
