24. The population of Bayside, CA increased from 23,560 in 1990. The annual rate of
population increase for the next 20 years was about 6%. Predict the population of Bayside in
2010.
Answer:
the population in 2010 is 75,656.33
Step-by-step explanation:
Given that
The increase in population in the year 1990 is 23,560
The Annual rate of interest is 6%
And, the time period is 20 years
We need to find out the population in 2010
So, the following formula should be used
= Population × (1 + rate)^time period
= 23,590 × (1 + 0.06)20
= 23,590 × 1.06^20
= 75,656.33
hence, the population in 2010 is 75,656.33

YOUR ASSIGNMENT: Desert Temperatures
In this assignment, you may work alone, with a partner, or in a small group. Discuss the results of your work and/or any lingering questions with your teacher.
Temperature in the desert can be modeled by the function C(t), where t represents hours after midnight (0 ≤ t ≤ 24), and C is the temperature measured in degrees Celsius. Examine what happens to the graph when you transform the function to degrees Fahrenheit.
Circle the desert you picked:
Sahara Desert
Patagonian Desert
Death Valley California(I choose this one)
Exploring Degrees Celsius
1. Fill out the following chart to find the temperatures for t = 12 (noon) and t = 24 (midnight). (2 points: 1 point for each row)
t
C(t) = –0.30(t – 12)2 + 40
0
12
C(t) = -0.30 (12 - 12)² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40
24
C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2
2. Plot the three points from the chart onto the graph below. Use the plotted points to sketch the graph of C(t) = –0.30(t – 12)2 + 40. (3 points: 2 points for correct coordinates, 1 point for correct shape)
Convert the Function to Degrees Fahrenheit:
3. Suppose you want to represent the desert temperature in degrees Fahrenheit instead. How would you transform the function C(t) to make the new function, F(t)? (2 points: 1 point for each transformation)
Note: The conversion rule for Celsius to Fahrenheit is .
F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
4. Take your values from the previous chart (in question 2) and convert them from Celsius to Fahrenheit. Follow the example below, and use the conversion rule to fill out the chart for degrees Fahrenheit when t = 12 and t = 24. (2 points: 1 point for each row)
t
0
12
24
5. Use the conversion formula to write the equation for the new function, F(t).
(4 points: 2 points for setting up the equation, 2 points for the answer)
Hint: Substitute the equation for C(t) into .
6. Plot the points from the Fahrenheit chart in question 4 onto the graph below. Use the plotted points to sketch out the graph of F(t). (3 points: 2 points for correct coordinates, 1 point for correct shape)
7. Compare the graph in question 6 (F(t)) with the graph in question 2 (C(t)). What changes were made to the graph of C(t) to transform it to F(t)? (1 point)
Answer:
Part 1
Given equation:
C(t) = -0.30 (t – 12)² + 40
For t = 0
C(t) = -0.30 (0 - 12)² + 40
C(t) = -0.30 (-12)² + 40
C(t) = -3.2
For t = 12 (noon)
C(t) = -0.30 (12 - 12)² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40
For t = 24 (midnight)
C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2
Part 2
attached below
Part 3
C(t) = –0.30(t – 12)² + 40
F(t)=9/5C(t)+32
Substituting the values:
F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
5, 6 and 7, should be simplish

A park in the shape of a right triangle, one leg of the triangle is 2 kilometers long, the hypotenuse measures 2.9 kilometers how long in kilometers is the other leg?
Answer:
2.1 kilometers
Step-by-step explanation:
Pythagoras' Theorem
a^2 + b^2 = c^2
2^2 + b^2 = 2.9^2
2.9^2 - 2^2 = b^2
8.41 - 4 = 4.41
b = √4.41
b= 2.1

Learning how to simplify an expression is the most important step in understanding and mastering algebra. Simplification of expressions is a handy mathematics skill because it allows us to change complex or awkward expressions into simpler and compact forms. But before that, we must know what an algebraic expression is.
An algebraic expression is a mathematical phrase where variables and constants are combined using the operational (+, -, × & ÷) symbols. For example, 10x + 63 and 5x – 3 are examples of algebraic expressions.
In this article, we shall learn a few tricks on how to simplify any algebraic expression.
How to Simplify Expressions?
Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.
The process entails collecting like terms, which implies adding or subtracting terms in an expression.
Let’s remind ourselves of some of the important terms used when simplifying an expression:
A variable is a letter whose value is unknown in an algebraic expression.
The coefficient is a numerical value used together with a variable.
A constant is a term that has a definite value.
Like terms are variables with the same letter and power. Like terms can sometimes contain different coefficients. For example, 6x2and 5x2 are like terms because they have a variable with a similar exponent. Similarly, 7yx and 5xz are unlike terms because each term has different variables.
To simplify any algebraic expression, the following are the basic rules and steps:
Remove any grouping symbol such as brackets and parentheses by multiplying factors.
Use the exponent rule to remove grouping if the terms are containing exponents.
Combine the like terms by addition or subtraction
Combine the constants

The length of a rectangle is twice as long as it's with the with is 104 inches find the perimeter of the rectangle
Answer:
624 inches
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Width = 104 inches
So, Length = 104 × 2 = 208 inches
Now, we can calculate the perimeter of rectangle by using following formula,
Perimeter of rectangle = 2 ( length + width)
By putting the value, we get
Perimeter of rectangle = 2 ( 208 + 104)
= 624 inches
Look at the equation below.

The area of the base of this cylinder is 25picm^2 and the height of the cylinder is 8cm. Find the surface area of the cylinder.
Answer:
408.2cm
Step-by-step explanation:
Given data
Area of base= 25πcm^2
Height= 8cm
Let us find the radius of the cylinder
Area= πr^2
25π= πr^2
25= r^2
r= √25
r= 5cm
Let us now find the surface area
SA=2πrh+2πr^2
Substitute
SA= 2*3.14*5*8+ 2*3.14*5^2
SA= 251.2+ 157
SA= 408.2cm
Hence the surface area is 408.2cm

MARKING BRAINLIEST IF U HELP 19 - s = 13; s = -6 yes no question
Answer:
Step-by-step explanation:
We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.
To solve, we need to isolate "s", do as followed and subtract 19 from both sides :
s = -6
Since this is equal to what the question is asking, yes s = -6 is correct.
