Well... if she has 8 yards, and a yard equals to 18 inches. So.. I would divide 8 and 1/4. After you do the reciprocal, you would get 32 pieces.

#6: Tell whether the function below is 1 point<br> linear or exponential.<br> *<br> f(x) = -1/4x + 5

Pachacha [2.7K]

Answer:

Linear function

Step-by-step explanation:

Given

$f(x) = -\frac{1}{4}x + 5$

Required

Linear or Exponential

A linear equation has the form: $f(x) = mx + c$ ;

An exponential has the form: $f(x) = ab^x$

By comparing both functions to: $f(x) = -\frac{1}{4}x + 5$

The linear function is similar to $f(x) = -\frac{1}{4}x + 5$

<em>Hence, the given function is a linear function.</em>

Use long division to find a repeated decimal equivalency for the fraction. This is a question that my teacher gave me for pre al

Dafna11 [192]

Take the fraction. Divide the top number by the bottom number. (That's what a fraction means.). Some fractions will produce a decimal that goes on and on and never ends. Some fractions produce a decimal that ends. Some examples that make repeating decimals are: 1/3, 1/7, 1/9, 1/11.

The electrical charge on a metal plate is given

Katarina [22]

Answer:

after 10 seconds the charge is 1.624

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one.

The electrical charge on a metal plate is given by the function below, where t is the time in seconds. What is the charge after 10 seconds?

C (t) = 12 $e^{\frac{-t}{5} }$

My answer:

Given the information:

C (t) = 12 $e^{\frac{-t}{5} }$

when t =10 we have:

C (10) = 12 $e^{\frac{-10}{5} }$

<=> C (10) = 12 $e^{-2}$

<=> C (10) = 12 $\frac{1}{e^{2} }$

<=> C (10) = 12 * 0.1353

<=> C (10) = 1.624

Hence, after 10 seconds the charge is 1.624

If z=5-2i then |z| is equal to what ?

Daniel [21]

<span>z=5-2i

</span><span>|z| = [ (5^2 + (-2)^2) ] ^ 0.5
= ( 25+4) ^ 0.5
= 29^0.5 </span>
