Answer:

50.58 m.

Step-by-step explanation:

a. Average is calculated by adding the sum of the numbers divided by the number of numbers

50.7 + 49.4 + 52.3 + 48.9 + 51.6 = 252.9

252.9 / 5 = 50.58

The average was 50.58 m.

A) Add the distances together and divide by the number of attempts:

50.7 + 49.4 + 52.3 + 48.9 + 51.6 = 252.9

252.9 / 5 = 50.58

The average was 50.58 m.

B) Add 52.5 to the total above and divide by 6:

252.9 + 52.5 = 305.4

305.4 / 6 = 50.9 m.

Now subtract the average from above:

50.9 - 50.58 = 0.32 difference.

Rewrite each equation in vertex form by completing the square. Then identify the vertex.

ioda

ANSWER

Vertex form;

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

Vertex

$V( - \frac{3}{2} , - \frac{35}{4} )$

EXPLANATION

Given:

$f(x) = 3 {x}^{2} + 9x - 2$

We complete the square as follows:

$y = 3( {x}^{2} + 3x) - 2$

$y = 3( {x}^{2} + 3x + \frac{9}{4} ) - 2 - 3 \times \frac{9}{4}$

The vertex form is:

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

The vertex is

$V( - \frac{3}{2} , - \frac{35}{4} )$

The sum of two numbers is 74. The larger number is 3 more than the smaller number. Find the numbers.

nlexa [21]

Answer: It's 35.5 and 38.5

Step-by-step explanation:

First, subtract 74 by 3 giving you 71.

Next, divide 71 by 2; it gives you 35.5 (that's your first number).

Then, add the 3 that you took away to 35.5 and get 38.5 (that's your second number).
