Answer:

t = -1

Step-by-step explanation:

-4 = 2t - 2

Add 2 on both sides.

-4 + 2 = 2t - 2 + 2

-2 = 2t

Divide both sides by 2.

-2/2 = (2t)/2

-1 = t

find the absolute error and percentage error in rounding; the yearly profit of $1367540 made by a company to $1.37 million ​
Savatey [412]

Answer:

0.18%

Step-by-step explanation:

% error= accepted value - experimental value/ accepted value

Step 1: subtract one value from another

1,367,540-1,370,00=-2460

Depending on what you need it you may take away the negative sign

Step 2: So your absolute error is equal to 2,460

Step 3: divide error by true value

= 2460/1,370,000

Ans = 0.0018

Step 4: multiply this value by 100% to obtain the percent error

0.0018 X 100% = 0.18%

Which function below is the inverse of f(x)= 3x+5/7
valkas [14]

Answer:

\huge\boxed{f^{-1}(x) = \frac{7x-5}{3}}

Step-by-step explanation:

Given the function:

f(x) = \frac{3x+5}{7}

Put f(x) = y

y = \frac{3x+5}{7}

Interchange x and y

x = \frac{3y+5}{7}

Solve for y

x = \frac{3y+5}{7}

Multiplying both sides by 7

7x = 3y+5

Subtracting y to both sides

7x-5 = 3y

Dividing both sides by 3

\frac{7x-5}{3} = y

<u>OR</u>

y = \frac{7x-5}{3}

Put y = f^{-1}(x)

So,

f^{-1}(x) = \frac{7x-5}{3}

Hope this helped!

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.
vekshin1

Simplify:

A(n) = -6 + (n - 1)(6) = -6 + (n)(6) + (-1)(6) = -6 + 6n - 6 = 6n - 12

Put n = 1, n = 4 and n = 10 to the expression:

A(1) = 6(1) - 12 = 6 - 12 = -6

A(4) = 6(4) - 12 = 24 - 12 = 12

A(10) = 6(10) - 12 = 60 - 12 = 48

<h3>Answer:</h3><h3>first term = -6, fourth term = 12 and tenth term = 48.</h3><h3>-6, 12, 48</h3>
