Answer:

I believe it is .0801

Step-by-step explanation:

- A negative exponent will always turn into a fraction

- First change it to a fraction

1/10^2

- Simplify the exponent

10 times 10 = 100

- Change the fraction

1/100 or in decimal form which is 0.01

- Now the addition

8 + 0.01 = 8.01

- Move decimal to two decimal places

.0801

Answer:    .0801 is what I got because the way I understand it 10^(-2) + 8 =8.01 and you said round it to the coefficient to 2 decimal places. so I moves the 8 over 2 times because 8 is the coefficient and I got .0801

Hope it helped and I got it right

Step-by-step explanation:

have a nice day!

The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Actual mass = 38

Danielle error = 40 - 38 = 2 grams

% error = 2/40 x 100 = 5%

Iris error = 4 - 34 = 6 grams

% error = 6/40 x 100 = 15%

HB error = 41 - 40 = 1 grams

% error = 1/40 x 100 = 2.5%

Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively".

Answer:y=4

Step-by-step explanation: Simplifying

1.5y + -6 = 0

Reorder the terms:

-6 + 1.5y = 0

Solving

-6 + 1.5y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 1.5y = 0 + 6

Combine like terms: -6 + 6 = 0

0 + 1.5y = 0 + 6

1.5y = 0 + 6

Combine like terms: 0 + 6 = 6

1.5y = 6

Divide each side by '1.5'.

y = 4

Simplifying

y = 4

The equivalent equation, if 6 is factored out from the expression is 6(0.25y - 1)

Given a linear equation y = mx + b where b is the constant.

Given the linear equation f(y) = 1.5y - 6, we can see that 6 is the constant in the expression.

Factoring out 6 from the expression

[tex]f(y) = 1.5y-1.6\\f(y)=6(\frac{1.5y}{6}-\frac{6}{6} )\\f(y)=6(\frac{0.25y}{1} -1)\\f(y) = 6(0.25y-1)[/tex]

Hence the equivalent equation, if 6 is factored out from the expression is 6(0.25y - 1)

We want to find the rate of change of the population of Austin, Texas in the years between 1980 and 1990.

The answer is: r = 12,600 people/year.

We will assume that this increase in population is modeled with a linear equation, remember that a general linear equation is:

y = a*x + b

Where the rate of change, or slope, is a.

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope is given by the formula:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For this case we have two points, these are:

(1980, 346,000)

(1990, 472,000)

Then the slope or rate of change is just:

[tex]a = \frac{472,000 - 346,000}{1990 - 1980} = 12,600[/tex]

To be complete we need to add the correspondent units, which are people per year.

Then the rate of change is:

r = 12,600 people/year.
