Find the perimeter of a square whose sides are 7.
allochka39001 [22]
Hey there,

Your question states: <span>Find the perimeter of a square whose sides are 7.

When finding the perimeter, we need to multiply each side because it is a square. So 7 times 4 would be 28

What is the inverse of the function f(x)=x/5-2
umka2103 [35]

Answer:

\huge\boxed{\sf f^{-1}(x)=5x+10}

Step-by-step explanation:

<h3>Given function:</h3>

\displaystyle f(x)=\frac{x}{5} -2

Put f(x) = y

\displaystyle y=\frac{x}{5} -2

Swap x and y

\displaystyle  x = \frac{y}{5} -2

Now, solve for y

\displaystyle  x = \frac{y}{5} -2

Add 2 to both sides

\displaystyle x + 2 =\frac{y}{5}

Multiply 5 to both sides

5(x+2)=y

Distribute

5x + 10 =y

Put y = f⁻¹(x)

\boxed{f^{-1}(x)=5x+10}

\rule[225]{225}{2}

A sample of radium has a weight of 1.5 mg and decays
Oliga [24]

Answer: (b)

Step-by-step explanation:

Given

Initial mass of radium is A_o=1.5\ mg

It decays by half every 6 years i.e. T_{\frac{1}{2}}=6

For radioactive decay, sample at any time is given by

\Rightarrow A=A_o2^{-\dfrac{t}{T_{\frac{1}{2}}}}

Insert the values

\Rightarrow A=1.5\cdot 2^{\dfrac{-t}{6}}\\\\\Rightarrow A=1.5\cdot \left(\dfrac{1}{2}\right)^{\dfrac{-t}{6}}\\\\\Rightarrow A=1.5\cdot (0.5)^{\dfrac{t}{6}}

Thus, option  (b) is correct.

If P(A)=2/3, P(B)=4/5, and P(AvB)=8/15, what is P(A^B)?
Triss [41]

Answer:

P(A^B) = 22/15 or 1 7/15

Step-by-step explanation:

To find the P (A^B), we add the probability of events A and B.

2/3 + 4/5 = P, we need to find the LCD to add disimilar fractions

LCD is 15.

2(5)/15 +4(3)/15 = 10/15 + 12/15 = 22/15
