Answer:

Q16a: 432 cm³

Q16b: sides: 20 m, 6 m; height: 13 m.

Step-by-step explanation:

Each cube will have a volume ...

V = s³

V = (6 cm)³ = 216 cm³

The two cubes together will have a volume that is twice that.

The cuboid volume is 432 cm³.

Let h represent the height of the trapezium. Then its area is ...

A = 1/2(b1 +b2)h

169 = 1/2((h +7) +(h -7))h = 1/2(2h²) = h²

h = √169 = 13 . . . . . distance between the parallel sides

The side lengths are h+7 = 20 m and h-7 = 6 m. The distance between them is 13 m.

A city has a population of 245,600 which is 110% of the population from the previous year. What was the population the previous

MrMuchimi

<h2>Answer:</h2><h2>The city population last year = 2233 approximately</h2>

Step-by-step explanation:

The current population of the city = 245,600

Rate of increase = 110 %

The population in previous year = ?

Let x be the population of previous year

x(110%) = 245600

x = $\frac{245600}{110}$

= 2232.7

The city population last year = 2233 approximately

End behavior of polynomials I give 20 points

raketka [301]

The end behavior of a polynomial is determined entirely by the leading term. For example, $2x^4-x+1$ behaves the same way as $2x^4$ when $x$ is very large in magnitude. All the problems in the picture are more or less the same. I'll pick out two examples:

1a) $f(x)=5x^6-3x^3-4x^2+8x$ behaves like $5x^6$ . $x^6$ will be positive regardless of the value of $x$ , so to either the left or right, the graph of $f(x)$ will approach positive infinity or "rise" on both the left and right sides.

1c) $f(x)=-4x(x-4)(x+2)$ has a leading term of $-4x^3$ , so $f(x)$ behaves like $-4x^3$ . When $x$ , we have $x^3$ , so that $-4x^3>0$ . This means $f(x)$ rises to the left. If $x>0$ , then $-4x^3$ , so $f(x)$ falls to the right.
