What is the completely factored form of t4 − 16?

Mathematics
1 answer:
Mashcka [7]3 years ago
7 0

we know that

A difference of squares problem can be factored as follows:

a^{2}-b^{2} =(a+b)(a-b)

in this problem we have

t^{4}-16

Applying difference of squares

t^{4}-16=(t^{2}-4)( t^{2}+4)

the term

(t^{2}-4)=(t+2)(t-2)

substitute

(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)

therefore

<u>the answer is</u>

(t+2)(t-2)( t^{2}+4)

24. Michael leaves his house at 0837 and travels by motorcycle to the railway station, which is 27 km from his
Neko [114]

Answer:

i) 45km/hr

ii)29 min

Step-by-step explanation:

average speed = distanced travelled / time elapsed

It took 36min and need to convert to hr

36min x \frac{hours}{60 min} = \frac{36 hr}{60 min} = \frac{9 }{15 } hours

distanced travelled is 27 km;

average speed = 27km / (9/15hr) = 45 km/hr

Add 36min to 0837 becomes 0913, the train will arrive at 0942 and the wait will be the difference of 0942 - 0913 = 29 min
