We have to find the solutions represented by point A on graph.

point A is represented (1 , 5i)

1. (1 - 4i) - (2 + i)

= 1 - 4i - 2 - i

= -1 - 5i

This option is not correct because it does not as same point as A.

2. -1(1 - 4i) + (2 + i)

= -1 + 4i + 2 + i

= 1 + 5i

This solution is same as point A so this option is correct.

3. (-1 + 4i) - (2 + i)

= -1 + 4i - 2 - i

= -3 + 3i

This option is not correct because it does not as same point as A.

4. (-1 + 4i) + (2 + i)

= -1 + 4i + 2 + i

= 1 + 5i

This solution is same as point A so this option is correct.

Therefore options 2 and 4 are correct.

write a quadratic function in vertex form whose graph has the vertex (1,0) and passes through point (2,-17)
kobusy [5.1K]

Answer:

\displaystyle f(x) = -17(x-1)^2

Step-by-step explanation:

We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).

Recall that vertex form is given by:

\displaystyle f(x) = a(x-h)^2 + k

Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.

Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:

\displaystyle f(x) = a(x-1)^2

It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:

\displaystyle (-17) = a((2)-1)^2

Solve for <em>a: </em>

<em />\displaystyle a = -17<em />

<em />

In conclusion, our quadratic function in vertex form is:

\displaystyle f(x) = -17(x-1)^2

A car travels 15 km in 13 minutes. What is its average speed in km/h?
Bogdan [553]

Answer:

  • 69.45 km/h

Step-by-step explanation:

  • Speed = Distance/Time
  • => Speed = 15 km ÷ 13/60
  • => Speed = 15 km ÷ 0.216
  • => Speed = 15 km/0.216
  • => Speed = 15 x 4.63/0.216 x 4.63
  • => Speed = 69.45 km/1 h (Approximate)

<u>Conclusion:</u>

  • Therefore, the speed is 69.45 km/h (Approximate)

Hoped this helped.
