Answer:

Step-by-step explanation:

To calculate the area of a triangle you will do it like a square or rectangle but you will divide your answer by 2. So...

10 * 6 = 60

60 / 2 = 30

Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

$Rate = \frac{f(b) - f(a)}{b - a}$

Where

$(a,b) = (2,4)$

So, we have:

$Rate = \frac{f(4) - f(2)}{4 - 2}$

$Rate = \frac{f(4) - f(2)}{2}$

Using the attached graph, we have:

$f(2) = 4$

$f(4) = 16$

So, we have:

$Rate = \frac{16- 4}{2}$

$Rate = \frac{12}{2}$

$Rate = 6$

Billy likes to go cycling.

Agata [3.3K]

Answer:

560 metres

Step-by-step explanation:

80 cm in metres is 0.8 metres.

After 1 revolution any point on the wheel will be back to the original position before moving. 0.8 times 2, which gives us 1.6 metres. In 1 revolution the bike travels 1.6 metres.

Now 1.6 metres times 350 gives us 560.

So the answer is 560 metres.

Which equation represents a parabola that has a focus of (0 0) and a directrix of y = 2

mel-nik [20]

ANSWER

$x ^{2} = - 4(y - 1).$

EXPLANATION

Since the parabola has the (0, 0) and the directrix at y=2.

The equation is of the form

${(x - h)}^{2} = - 4p(y - k)$

where (h,k) is the vertex.

The vertex is half way between the directrix and the focus.

The vertex will be at (0,1)

and is the distance from the vertex to the focus which is 1.

${(x - 0)}^{2} = - 4(1)(y - 1)$

$x ^{2} = - 4(y - 1)$
