AnnyKZ [126]

Answer:

(1). $5^{4}$ × $13^{7}$ ; (2). 3 - 5x

Step-by-step explanation:

1). [( - 5 )³ · ( - 5 )] ( $13^{-2}$ · $13^{9}$ ) = $(-5)^{3+1}$ × $(13)^{-2+9}$ = $(-5)^{4}$ × $13^{7}$ = $5^{4}$ × $13^{7}$

2). - 25x² ÷ 5x + 15x ÷ 5x = 3 - 5x

Question Help

lorasvet [3.4K]

Answer:

The speed of the boat is 20 km/hr

Step-by-step explanation:

Let s be the speed of boat in still water

Let d be the distance

Upstream speed = s-4

Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.

So, Distance traveled in upstream = $Speed \times time =(s-4) \times \frac{30}{60}$

Downstream speed = s+4

So, Distance traveled in downstream = $Speed \times time =(s+4) \times \frac{20}{60}$

So, $(s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}$

30s-120=20s+80

10s=200

s=20

Hence The speed of the boat is 20 km/hr

If (x+2) is a Factor x^3 + 2x^2 + 2x + k then find the value of K.

Delvig [45]

Answer:

Step-by-step explanation:

If (x + 2) is a factor of a polynomial then ( - 2 ) is the zero of that polynomial ⇒ ( - 2 )³ + 2( - 2 )² + 2( - 2 ) + k = 0 ⇒ k = - 4
