Find the value of the expression
96 (32÷n÷ 2)-s-t^r
for n = 4, r = 3, s = 9, and t = 2.
Answer:
1,519
Step-by-step explanation:
96 ( 32 ÷ n ÷ 2 ) –s –t^r
since n = 4, r = 3, s = 9, and t = 2. we will just substitute for the values like this
96 ( 32 ÷ (4 ÷ 2) ) –9 ( –2³)
96 ( 32 ÷ 2 ) –9 –8
96 ( 16 ) –17
=1,536 –17

An initial sample of 171 g of a radioactive substance decays according to the function
A(t) = 171e ^ - 0.04(t) where t is given in years?
a) How many grams of the substance will remain after 59 years? Round your answer to the nearest decimal place.
b) What is the half-life of the substance? Round answer to the one decimal place.
There will be 0.48 grams will be left in the sample after 59 years.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Since we have given that initial sample of 171 g of a radioactive substance decays according to the function
[tex]A(t) = 171e ^ {- 0.04(t) }[/tex]where t is given in years
Here, Initial amount of radioactive substance = 171 grams
We need to find the amount of substance that will be left in the sample after 59 years.
So, t = 59 years
So, it becomes,
[tex]A(t) = 171e ^ {- 0.04(59) }\\\\A(t) = 0.48[/tex]
Hence, there will be 0.48 grams will be left in the sample after 59 years.

Define Parallelogram.A unique variety of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
The parallelogram's diagonals are the lines connecting its two opposed ends. Sharing into two equal portions is known as bisecting. Congruent refers to a copy that has the same dimensions as the original and may therefore be used in place of it. When the diagonals of a parallelogram bisect one another, it signifies that they split into two equal pieces that are congruent with one another.

Your body mass index (BMI) is your weight by kilograms divided by the square of your height in meters. Online BMI calculators allow you to enter weight in pounds and height in inches. High BMI is a common but controversial indicator of being overweight or obese. A study by the National Center for Health Statistics found that the BMI of American young women (ages 20-29) is approximately Normally distributed with mean 26.8 and standard deviation 7.4
Using z-score calculations, we can say that around 13.14%of the young women have a BMI (Body Mass Index) of less than 18.5 and are underweight.
How to find the probability from z-score?The formula for z-score is;
z = (x' - μ)/σ
We are given;
Population Mean; μ = 26.8
Population standard deviation; σ = 7.4
Average BMI; x' = 18.5
Thus;
z = (18.5 - 26.8)/7.4
z = -1.12
From online p-value from z-score calculator, we have;
p-value = 0.1314 = 13.14%

A collector's model racecar is scaled so that 1 inch on the model equals 6 1/4 feet on the actual car. If the model is 2/3 inch high, how high is the actual car? explain
Answer:
50 inches, or 4 1/6 feet
Step-by-step explanation:
If one inch is equal to 6 1/4 feet, we can translate this number from feet to inches.
4 1/6 feet = 75 inches.
Now we can take 75 and find out 2/3 of it.
2/3 of 75 is 50.
The answer is 50 inches.
If you want to convert the answer from feet to inches, its simple.
12 × 4 = 48
50 - 48 = 2
2 inches is equal to 1/6 of a foot.
The answer in feet, is 4 1/6 foot.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of rides = m + 5
Number of games = m
Now,
Each game costs $1.50 and each ride costs $5. Isaac spent $44.50 altogether at the carnival.
This means,
1.50m + 5(m + 5) = 44.50
1.50m + 5m + 25 = 44.50
6.50m = 44.50 - 25
m = 19.5/6.50
m = 3
Now,
The number of games = 3.

If log₂(4x + 6) = 4, then x = ____
You may enter the exact value or round to 4 decimal places.
Answer: -1/2
Step-by-step explanation: To solve this problem, we can use the properties of logarithms to isolate the variable x on one side of the equation. The properties of logarithms tell us that the logarithm of a product is the sum of the logarithms of the factors, and that the logarithm of a power is the exponent times the logarithm of the base.
If log₂(4x + 6) = 4, we can rewrite the left side of the equation as follows: log₂(4x + 6) = log₂(2^4 * (2x + 3))
Then, using the property of logarithms that the logarithm of a product is the sum of the logarithms of the factors, we can simplify the equation as follows: log₂(4x + 6) = 4 + log₂(2x + 3)
Now, we can use the property of logarithms that the logarithm of a power is the exponent times the logarithm of the base to simplify the equation even further: log₂(4x + 6) = 4 + 1 * log₂(2x + 3)
Since the logarithm of a power is the exponent times the logarithm of the base, this means that the logarithm of a number is the logarithm of that number divided by the logarithm of the base. Therefore, we can divide both sides of the equation by log₂ to isolate the variable x on one side of the equation:
log₂(4x + 6) / log₂ = 4 + 1 * log₂(2x + 3) / log₂
(4x + 6) / 1 = 4 + (2x + 3) / 1
4x + 6 = 4 + 2x + 3
4x + 6 = 2x + 7
2x = -1
x = -1/2
Therefore, if log₂(4x + 6) = 4, then x = -1/2.

According to Newton's Law of Cooling, if a body with temperature T₁ is placed in surroundings with temperature To, different
from that of T₁, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = To + (T₁-To)ekt
A metal pan with temperature 120°F is placed in a freezer with temperature 0°F. After 5 minutes, the temperature of the pan
is 80°F. Use Newton's Law of Cooling to find the pan's temperature after 15 minutes.
After 15 minutes the pan will have a temperature of °F.
(Round to the nearest integer.)
After 15 minutes the pan will have a temperature of 36°F
How to determine the temperature of the pan after 15 minutes?
Newton's Law of Cooling, if a body with temperature T₁ is placed in surroundings with temperature To, different from that of T₁, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = T₀ + (T₁-T₀)e^(kt)
Given: T₁ = 120°F, T₀ = 0°F. After 5 minutes, T(t) = 80°F
T(t) = T₀ + (T₁-T₀)e^(kt)
80 = 0 + (120-0)e^(5k)
80 = 120e^5k
e^5k = 80/120
e^5k = 2/3
5k = ln(2/3)
k = ln(2/3) / 5
k = -0.0811
The temperature of the pan after 15 minutes will be:
T(t) = T₀ + (T₁-T₀)e^(kt)
T(15) = 0 + (120-0)e^(-0.0811×15)
T(15) = 120e^(-0.0811×15)
T(15) = 36°F
