Answer:

72 beats per minute

Step-by-step explanation:

Given data :

Original pulse rate = 80 beats per mint

Reduction = 10%

Decrease in the number of beats per minute = 80 × 10/100 = 8

Hence, new pulse rate = 80 - 8 = 72 beats per minute.

Thus, the new pulse rate will be 72 beats per minute

Find the value of x. Using trig
scoundrel [369]

Hi there! We can find the value of x by using this equation.

\large \boxed{tanx =  \frac{19}{23} }

If you remember, tanx = opposite/adjacent. We focus on the angle x currently.

Now that you might wanna ask if there is a value of x that makes 19/23. The answer is yes but in decimal.

\large{arctan( \frac{19}{23} )} = x

You might wanna put arctan(19/23) in a calculator since it's not really possible to get the square root like value by yourself.

arctan(19/23) is 0.69

Then we round up and get 0.7

Hence, the value of x ≈ 0.7

Answer

  • x ≈ 0.7 (rounded)

Questions can be asked through comment.

Hope it helps, and Happy Learning! :)

Find the inverse of 2∛(x+2)
Artemon [7]
y=2\sqrt[3]{x+2}\ \ \ |divide\ both\ sides\ by\ 2\\\\\sqrt[3]{x+2}=\dfrac{y}{2}\to x+2=\left(\frac{y}{2}\right)^3\ \ \ |subtract\ 2\ from\ both\ sides\\\\x=\dfrac{y^3}{2^3}-2\\\\x=\dfrac{1}{8}y^3-2\\\\\boxed{f(x)=2\sqrt[3]{x+2}\to f^{-1}(x)=\frac{1}{8}y^3-2}

Iteru [2.4K]

Answer:

1a - reduction

2a- enlargement

3a- reduction

4a- enlargement

Step-by-step explanation:

when the scale factor is greater than 100% it is making it larger, when less than 100% size it is making it smaller. for every answer do the original number (ex #1 would be 48 inches) and multiply it by the scale factor in decimal form, by moving the decimal over two places (ex #1 the 25% would become .25 or 1/4). therefore #1 would be an equation like 48 x 0.25= 12
