Which ordered pairs lie on the graph of the exponential function
f(x) = 3(1/4)^x
Select each correct answer.
A. (−2,48)
B. (0,3)
C. (2,3/16)
D. (12,0)
Answers
when x=0, f(3)=3(1/4)^0
any number to the 0th power is 1, so f(3)=3*1=3
A, C are also correct. (1/4)^-2=16, (1/4)^2=1/16
Answer:
A. (−2,48) B. (0,3) C. (2,3/16) Step-by-step explanation:
The given function is
[tex]f(x)=3(\frac{1}{4} )^{x}[/tex]
To find those ordered pairs that lie on the graph, we need to evaluate each of them
A. (−2,48)
[tex]f(-2)=3(\frac{1}{4} )^{-2}=3(4)^{2}=3(16)=48[/tex]
This pair lies on the graph.
B. (0,3)
[tex]f(0)=3(\frac{1}{4} )^{0}=3(1)=3[/tex]
This pair lies on the graph.
C. (2,3/16)
[tex]f(2)=3(\frac{1}{4} )^{2}=3(\frac{1}{16} )=\frac{3}{16}[/tex]
This pair also lies on the graph.
D. (12,0)
[tex]f(12)=3(\frac{1}{4} )^{12}=\frac{3}{16,777,216}[/tex]
This pair doesn't lie on the graph, because it doesn't satisfy the exponential function.
Therefore, the right asnwer are A, B and C.

What would the difference in elevation be if the lake had formed 149 feet above sea level?
Answers
The difference in elevation if the lake had formed 149 feet above sea level is 1788 feet.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
We have been given that Oakland has an elevation of 1,639 feet above sea level.
And Lake enriquillo’s elevation is 149 feet below sea level.
We have to determine the difference in elevation if the lake had formed 149 feet above sea level.
So the difference in elevation if the lake had formed 149 feet above sea level as
⇒ 1639 - (-149)
⇒ 1639 + 149
⇒ 1788.
Hence, the difference in elevation if the lake had formed 149 feet above sea level is 1788 feet.

Mario took clothes to the cleaners three times last month. first, he brought 3 shorts and 1pair of slacks and $10.96. then, he brought 7 shirts, 2 pairs of slacks, and a sports coat and paid $30.40. finally, he brought 4 shirts and 1 sports coat and paid$14.45. How much was he charged for each shirt, each pair of slacks, and each sports coat.
Answers
Each shirt costs approximately $0.66, each pair of slacks costs approximately $8.97, and each sports coat costs approximately $11.80.
Explanation:To find the cost of each item, we need to solve a system of equations. Let x be the cost of each shirt, y be the cost of each pair of slacks, and z be the cost of each sports coat. From the given information, we can set up the following equations:
3x + y = 10.96
7x + 2y + z = 30.40
4x + z = 14.45
Now, we can solve the system of equations using any method of our choice. Let's use the method of substitution:
From equation 1, we can solve for y: y = 10.96 - 3x.
Substituting this value of y into equation 2, we get: 7x + 2(10.96 - 3x) + z = 30.40.
Simplifying and rearranging this equation gives us: -5x + z = 8.48.
Now, we can solve for z in terms of x from equation 3: z = 14.45 - 4x.
Substituting this value of z into the equation we obtained earlier, we get: -5x + (14.45 - 4x) = 8.48.
Simplifying and rearranging this equation gives us: -9x + 14.45 = 8.48.
Now, we can solve for x:
-9x = 8.48 - 14.45
-9x = -5.97
x = -5.97 / -9
x = 0.6633
Therefore, each shirt costs approximately $0.66.
Now that we know the value of x, we can substitute it back into equation 3 to find the cost of each sports coat:
z = 14.45 - 4(0.6633)
z = 14.45 - 2.6532
z = 11.7968
Therefore, each sports coat costs approximately $11.80.
Finally, we can substitute the values of x and z into equation 1 to find the cost of each pair of slacks:
3(0.6633) + y = 10.96
1.99 + y = 10.96
y = 10.96 - 1.99
y = 8.97
Therefore, each pair of slacks costs approximately $8.97.
On a chess board, 32 of the squares are white. At the start of a game, the players cover 16 white squares of the board with pieces. In simplest form, what fraction of the white squares has chess pieces?
Answers
16/32 = 1/2
Half of the white squares on a chess board have pieces on them at the start of a game. This is represented by the simplified fraction 1/2.
To calculate what fraction of the white squares on a chess board has chess pieces at the start of the game, you start by considering the total number of white squares. A chess board consists of 64 squares, half of which are white, giving us a total of 32 white squares. At the start, 16 white squares are covered with pieces. Therefore, the fraction of white squares that have chess pieces is 16 out of 32 (16/32).
To simplify this fraction, you look for the greatest common divisor of both the numerator and the denominator. In this case, both 16 and 32 are divisible by 16. After simplifying, 16 divided by 16 gives you 1, and 32 divided by 16 gives you 2, so the simplest form of the fraction is 1/2.

A reasonable estimate for the height of a skyscraper is A. 1 x 10^3 feet, as it translates to 1,000 feet which is within the typical range for skyscrapers.
The reasonable estimate for the height of a skyscraper would be A. 1 x 10^3 feet. Option B is incredibly too high as no building is 1 x 10^8 feet tall. Option C and D are also incorrect as they represent very small sizes that are practically negligible and certainly not suitable for a building. A height of 1 x 10^3 feet is a reasonable approximation because it equates to 1,000 feet, which is well within the range of normal skyscrapers.

Explanation:A real-life problem that involves dividing a decimal by a whole number is calculating the average score of a student in a class. For example, if a student scores 85.4, 72.6, 90.2, and 65.3 on four tests, we can divide the sum of these scores (313.5) by the total number of tests (4) to find the average score (78.375).

Alex has 7 pizzas he wants to share equally with 10 friends. How much pizza will each friend receive?
Answers
Alex will give each of his friends 7/10 or 0.7 of a pizza when he divides 7 pizzas equally among 10 friends.
Alex has 7 pizzas and wants to share them equally with 10 friends. To find out how much pizza each friend will receive, we can set up a division problem: . This means each person gets 7/10 of a pizza.
Using fractional parts as one method, we can visualize slicing each pizza into 10 equal parts and each friend getting 7 of those slices. Therefore, each person ends up with 7 slices, where each slice is 1/10 of a whole pizza. Hence, every friend gets 7/10 or 0.7 of a pizza when it is divided equally.
Each friend will get 7 tenths of a pizza, or more practically, each friend will receive 0.7 of a pizza.
To solve the problem, we need to divide the total number of pizzas Alex has by the number of friends he wants to share them with.
Alex has 7 pizzas, and he wants to share them equally with 10 friends.
The division of pizzas per friend can be represented by the fraction:
[tex]\[ \text{Pizzas per friend} = \frac{\text{Total pizzas}}{\text{Number of friends}} \][/tex]
[tex]\[ \text{Pizzas per friend} = \frac{7}{10} \][/tex]
[tex]\text{Pizzas per friend} = 0.7[/tex]

Maria and Edwin have $23.00 each to spend at a book fair, where all students receive a 25% discount. They both want to purchase a copy of the same book, which normally sells for $26.50 plus 10% sales tax. To check if she has enough to purchase the book, Maria takes 25% of $26.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Edwin takes 75% of the normal purchase price and then computes 110% of the reduced price. Is Maria correct? Is Edwin correct? Do they have enough money to purchase the book? Explain your answer using complete sentences, and show your work.

@SignoraPenguino
Answers
Answer:
Step-by-step explanation:
They are both correct, the only difference is Maria did a two step process and Edwin did a one step process the total amount it would cost is $21.87 with $1.13 left over.
The way Maria calculates the final price of the book is correct. We know that the book normally sells for $26.50 plus a 10% sales tax. We also know that the students will receive an additional 25% discount. We must understand that the sales tax is applied to the discounted price. So first we will calculate 25% of 26.50 and subtract it from that amount. So the price will then be: (26.50 - 6.625). The price is now $18.34. Then to calculate the tax, it will be (10% * 18.34), so 1.834. We add this amount to the discounted price so: (18.34+1.834) = 20.12.
The final price of the book is $20.12 and Maria can get it and still save a little money.

What is the perimeter of a triangle if the lengths of the sides are 8", 10", and x?
Answers
So here is where you use the formula:
Replace x and y with 8 and 10
8²+10²=c²
Now simplify the equation
8² = 64
10² = 100
64+100=c²
164=c²
now you have to remove that ² from c. So basically you cancel it by square rooting it. But if you square root one side, you have to square root the other side.
√164 = √c²
√ and ² cancel each other out...
c = √164
√164 = 12.8
c= 12.8
Wait! we're not done yet cause now you have to find the perimeter of the triangle.
12.8+8+10
=30.8
Hope this helps!
