Reciprocal means to flip a fraction, so all we have to do is flip 11/12. 11/12= $\boxed{ \frac{12}{11}}$ . Hoped I helped. :)

To find the reciprocal you switch the numerator and denominator, so the reciprocal is 12/11.

Answer:

The hourly decay rate is of 1.25%, so the hourly rate of change is of -1.25%.

The function to represent the mass of the sample after t days is $A(t) = 810(0.74)^t$

Step-by-step explanation:

Exponential equation of decay:

The exponential equation for the amount of a substance is given by:

$A(t) = A(0)(1-r)^t$

In which A(0) is the initial amount and r is the decay rate, as a decimal.

Hourly rate of change:

Decreases 26% by day. A day has 24 hours. This means that $A(24) = (1-0.26)A(0) = 0.74A(0)$ ; We use this to find r.

$A(t) = A(0)(1-r)^t$

$0.74A(0) = A(0)(1-r)^{24}$

$(1-r)^{24} = 0.74$

$\sqrt[24]{(1-r)^{24}} = \sqrt[24]{0.74}$

$1 - r = (0.74)^{\frac{1}{24}}$

$1 - r = 0.9875$

$r = 1 - 0.9875 = 0.0125$

The hourly decay rate is of 1.25%, so the hourly rate of change is of -1.25%.

Starts out with 810 grams of Element X

This means that $A(0) = 810$

Element X is a radioactive isotope such that its mass decreases by 26% every day.

This means that we use, for this equation, r = 0.26.

The equation is:

$A(t) = A(0)(1-r)^t$

$A(t) = 810(1 - 0.26)^t$

$A(t) = 810(0.74)^t$

The function to represent the mass of the sample after t days is $A(t) = 810(0.74)^t$

bogdanovich [222]

Answer:

Step-by-step explanation:

Step 1:

- 21w + 9 + 8w = - 5w - 5

Step 2:

- 13w + 9 = - 5w - 5

Step 3:

- 7w + 9 = - 5

Step 4:

- 7w = - 14

Step 5:

14 = 7w

Answer:

w = 2

Find the equation of the line that passes through he points (2,6) and (-2,4)

stepan [7]

First Find slope by using $\frac{y2-y1}{x2-x1}$

$\frac{4-6}{-2-2} = \frac{-2}{-4} = \frac{1}{2}$

Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)= $\frac{1}{2}$ (x-2)
y-6= $\frac{1}{2} x-1$
y= $\frac{1}{2} x+5$ is your equation
