1/3ab^2 Solve for a

Julli [10]

Answer:

a = 18/b²

Step-by-step explanation:

Step 1: Write equation

1/3ab² = 6

Step 2: Solve for a

Multiply both sides by 3: ab² = 18
Divide both sides by b²: a = 18/b²

Isabella ran the 100-meter dash five times. The time it took her to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.

Stells [14]

Given:

Number of 100-meter races = 5

The time it took Isabella to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.

To find:

The decimals in order from greatest to least.

Solution:

The time it took Isabella to complete each race, in seconds, was shown below:

12.7, 12.807, 12.78, 12.08, 12.087

We need to arrange this data in descending order.

In all 5 numbers the digits before decimals are same. On comparing the digits on the tenth place and hundredth place, we get

12.807 > 12.78 > 12.7 > 12.087 > 12. 08

Therefore, the required order of given data is 12.807, 12.78, 12.7, 12.087, 12. 08.

Pls help Enter the equation for the graph.

prisoha [69]

Answer:

$y=[1]cos([\frac{2\pi }{3}]x)$

Step-by-step explanation:

Looking at the graph, we can see the domain to be from (0 , 2π).

Now we have to find one period that corresponds to cos(x).

The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.

b = 2pi/3

a is the same range as cos(x). Range: (0,0)

y = [a] * cos ([b]*x)

y = [1] * cos([2pi/3]x)

0.5(x^4 − 9) + 17 Combine like terms.

galben [10]

Hello from MrBillDoesMath!

Answer:

0.5 x^4 + 12.5

Discussion:

Only the constant terms are "like" and can be combined. Nothing combines with x^4.

0.5 ( x^4 - 9) + 17 =

0.5 x^4 - 0.5 (9) + 17 = as 0.5(9) = 4.5

0.5x^4 - 4.5 + 17 =

0.5 x^4 + 12.5

Thank you,

MrB
