Answer:

(Figure 1) Hence squaring both sides of an inequality will be valid as long as both sides are non-negative. Since square roots are non-negative, inequality (2) is only meaningful if both sides are non-negative. ... Hence, squaring inequalities involving negative numbers will reverse the inequality.

Enter the degree of the polynomial below.<br> 6x^6+ 9x^3+ 3x^2 - 4x^10 - 9x^5 – 5x^6

mafiozo [28]

The degree of a polynomial is simply the monomial with a coeficient that has the highest degree.

6x^6 = 6 degree

9x^3 = 3 degree

3x^2 = 2 degree

-4x^10 = 10 degree

-9x^5 = 5 degree

-5x^6 = 6 degree

Because -4x^10 has the highest degree, the degree of this polynomial is 10.

A train leaves at 11:32 and arrives at 13:24. It travelled at an average speed of 85 km/h.

Blababa [14]

Answer:

Step-by-step explanation:

<h3>Time used for journey = </h3>

13 : 24 - 11 : 32 = 1 : 92

1 : 92 = 1 hour 92 minutes

1 hour 92 minutes = 2 hours 32 minutes

<h3>changing 32 minutes to hours</h3>

1 h = 60 min

x = 32 min

x= 32 /60

x= 8/15 hours

<h3>Adding the 2hours to 8/15 hours</h3>

8/15 h + 2 h = 38 / 15

<h3>Using formula for distance</h3>

Distance = Speed × Time

Distance = 85km / h × 38 /15 h

Distance = 33.15 km

To 1DP = 33.2
