Answer:

  Q16a: 432 cm³

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

Step-by-step explanation:

<h3>Q16a</h3>

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.

__

<h3>Q16b</h3>

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.

\large\text{So, when you  think of think of the word \underline{of} think of its asking you to}\\\large\text{\bf multiply }

\large\text{Now that we got that run down out of the way lets answer your given}\\\large\text{question}

\large\textsf{0.25\% of 2,000}

\large\textsf{= 0.25\%} \times \large\textsf{2,000}

\large\textsf{0.25\%} = \mathsf{\bf \dfrac{25}{100}}

\mathsf{= \dfrac{25}{100} \times 2,000}

\mathsf{\dfrac{25}{100}= \bf 0.0025}

\large\textsf{= 0.0025} \times \large\textsf{2,000}
