Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

The function y = log (x) is translated 1 unit right and 2 units down. Which is the graph of the translated function?
On a coordinate plane, a curve starts at (negative 1, negative 5) and curves up into quadrant 1. It approaches y = 1.
On a coordinate plane, a curve starts at (1, negative 4) and curves upwards. It approaches y = negative 1.
On a coordinate plane, a curve starts at (negative 1, negative 1) and curves up into quadrant 1. It approaches y = 5.
On a coordinate plane, a curve starts at (1, negative 3) and curves up into quadrant 1. It approaches y = 5.
See the graph below
Explanation:
We need to remember the following rules:
[tex]For \ any \ function \ f(x) \ we have: \\ \\ \\ \bullet \ g(x)=f(x-k) \ Translation \ k \ units \ to \ the \ right \\ \\ \bullet \ g(x)=f(x+k) \ Translation \ k \ units \ to \ the \ left \\ \\ \bullet \ g(x)=f(x)+c \ Translation \ c \ units \ up \\ \\ \bullet \ g(x)=f(x)-c \ Translation \ c \ units \ down \\ \\ With \ c>0 \ and \ k>0[/tex]
Here we know that The function y = log (x) is translated 1 unit right and 2 units down, so:
[tex]k=1 \\ \\ c=2 \\ \\ \\ Finally: \\ \\ g(x)=log(x-1)-2[/tex]

Recipe for cookies calls for 3 1/4 cups of sugar Amy has already put three and one nights cup how many more cups so she need to put in
Answer:
So she need [tex]\frac{5}{36}\ cups[/tex] more to put in.
Step-by-step explanation:
Given:
Recipe for cookies calls for 3 1/4 cups of sugar.
Amy has already put three and one nine cups.
Now, to find the number of cups she need to put in.
Number of cups of sugar for recipe calls = [tex]3\frac{1}{4} =\frac{13}{4}\ cups.[/tex]
Amy has already put = [tex]3\frac{1}{9} =\frac{28}{9}\ cups.[/tex]
So, to get the number of cups she need to put in we subtract number of cups of sugar for recipe calls from number of cups of sugar for recipe calls:
[tex]\frac{13}{4} -\frac{28}{9}[/tex]
Subtracting by taking the same denominator:
[tex]=\frac{117-112}{36}[/tex]
[tex]=\frac{5}{36}[/tex]
Therefore, so she need [tex]\frac{5}{36}\ cups[/tex] more to put in.

A politician’s support grew from 42% by 3 percentage points to 45%. What percent (relative) change is this?
Answer:
The percent (relative) change is 7.14 percent (%).
Step-by-step explanation:
We are given that the original support value is at 42%.
Then the support increased by 3%, to reach 45%.
We want the Percentage Change (i.e. relative) change of this increase, which can be computed as:
[tex]\frac{X_{F}-X_{O}}{X_{O}}*100[/tex]
where [tex]X_{F}[/tex] is the final value reached
[tex]X_{O}[/tex] is the original value
So plugging in our known values and computing we have:
[tex]\frac{45-42}{42}*100= \frac{3}{42}*100 = 0.071428*100=7.14[/tex] percent increase.
Now lets go back and check if we are correct.
[tex]42+42\frac{7.14}{100}=42+2.9988=42+3=45[/tex]

About 106 baby boys are born for every 100 baby girls. Write this as a simplified ratio of males to females
Answer:
53/50
Step-by-step explanation:
The ratio of males to females is 53:50.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Number of baby boys = 106
Number of baby girls = 100
So, the ratio of males to females
= 106/100
= 53/50
Hence, the ratio of males to females is 53:50.

(a) Write out the first four terms of this sequence.
(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.
The complete question is:
A geometric sequence is defined recursively by
[tex]a_{(1)}=40\text{ and }a_n=(-1/2)a_{(n-1)}[/tex]
(a) Write out the first four terms of this sequence.
(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.
Answer:
The 9th term is larger than 1/10.Explanation:
You are given the first term, [tex]a_(1)=40[/tex] , and the recursive formula
[tex]a_{(n)}=(-1/2)a_{(n-1}[/tex]
Thus, you can find the sequence of terms by multiplying each term by the constant ratio, (-1/2).
(a) First four terms of the sequence
[tex]a_{(1)}=40\\ \\ a_{(2)}=40\times (-1/2)=-20\\ \\ a_{(3)}=-20\times (-1/2)=10\\\\ a_{(4)}=10\times (-1/2)=-5[/tex]
Those are the first four terms.
(b) 9th term
You can write the explicit formula of the sequence as:
[tex]a_{(n)}=a_{(1)}\times r^{(n-1)}\\ \\ a_{(n)}=40(-1/2)^{(n-1)}[/tex]
Thus, for the 9th term, n = 9, and the term is:
[tex]a_{(9)}=40\times (-1/2)^{(9-1)}\\ \\ a_{(9)}=40\times(-1/2)^8\\ \\ a_{(9)}=40\times(1/256)=0.1526[/tex]
Since 1/10 = 0.1, and 0.1 < 0.1526, the 9th term is larger than 1/10.
21. Three vertices of DEFG are D(2,3),E(-5,2),G(6,6). Find the coordinates of F.
The calculated coordinates of the point F is (-1, 5)
How to determine the coordinates of F
From the question, we have the following parameters that can be used in our computation:
D(2,3),E(-5,2),G(6,6)
We have that
The quadrilateral DEFG is a parallelogram
This means that the opposite sides have equal slopes
i.e.
Slope of DE = Slope of FG
Using slope formula, we have
(3 - 2)/(2 + 5) = (y - 6)/(x - 6)
This gives
1/7 = (y - 6)/(x - 6)
Cross multiply
x - 6 = 7y - 42
x = 7y - 36
Set y = 5
So, we have
x = 7 * 5 - 36
x = -1
So, we have
(x, y) = (-1, 5)
Hence, the coordinates of the point F is (-1, 5)
Question
Consider the parallogram DEFG with three vertices D(2,3),E(-5,2),G(6,6). Find the coordinates of F.
Final answer:
To find the coordinates of vertex F in the parallelogram DEFG with given vertices D(2,3), E(-5,2), and G(6,6), we can use vector subtraction to deduce that the coordinates of F are (-1, 5).
Explanation:
The question requires us to find the coordinates of vertex F of the quadrilateral DEFG given that we have the coordinates of vertices D(2,3), E(-5,2), and G(6,6). Assuming that DEFG is a parallelogram (as the question implies a symmetry-based approach though it doesn't specify), we can find F using the properties of parallelograms, which dictate that opposite sides are equal and parallel. The vector from D to E is ∂D = (-5 - 2, 2 - 3) = (-7, -1), and the vector from G to F (let's call it F's coordinates (x, y)) would be equivalent, as they are opposite sides. So, G + ∂D = F. Substituting G's values, we get (6 - 7, 6 -1), which simplifies to (-1, 5). Thus, the coordinates of F are (-1, 5).

U square both sides or all the equation. the square cancels out and on the other side, it will be the square root of a. Next, divide by r on each sides. The r cancels out. Then it's gonna be pie =the square root of a all over r. It can't be a/r square because in the original...pie is being multiplied by r which is squared so that means both variables are squared.

Step-by-step explanation:
The y-intercept is [tex]\frac{1}{2}[/tex].
Given that f(x) = 4x-2.
To find the inverse function:
1) Write f(x) = y
2) Switch x and y.
3) Solve for y.
4) Write [tex]y=f^{-1}\left(x\right)[/tex].
So,
[tex]f(x) = 4x - 2\\y=4x-2\\x=4y-2\\4y=x+2\\y=\frac{\left(x+2\right)}{4}\\y=\frac{1}{4}x+\frac{2}{4}\\y=\frac{1}{4}x+\frac{1}{2}\\f^{-1}\left(x\right)=\frac{1}{4}x+\frac{1}{2}[/tex]
Comparing this with y=mx+b,

There are 100 students at a swim meet. Every 3rd finisher in the race receives a medal. Every 5th finisher gets a ribbon. How many people will receive a medal AND ribbon.
Final answer:
Calculating the least common multiple (LCM) of 3 and 5 to determine that 6 students will receive both a medal and a ribbon at a swim meet of 100 students.
Explanation:
To find the number of students at the swim meet who will receive both a medal and a ribbon, we need to look for the common multiples of 3 and 5, as medals are given to every 3rd finisher and ribbons to every 5th finisher. The least common multiple (LCM) of 3 and 5 is 15, which means every 15th student will receive both a medal and a ribbon. Since there are 100 students, we simply divide 100 by 15 and then take the integer part of the result, because we can't have a fraction of a person.
100 ÷ 15 equals approximately 6.66. The integer part is 6, which means 6 students will receive both a medal and a ribbon.
