please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
Part A)
She needs to compare by division the following two numbers:
8 × 10^-6 and 4 × 10^-5
If she divides the whole parts and then divides the powers of ten, she must do both divisions in the same order.
That means either
a) divide 8 by 4, and then divide 10^-6 by 10^-5
or
b) divide 4 by 8, and then divide 10^-5 by 10^-6
Doing a), you get
8/4 = 2
10^-6 / 10^-5 = 0.1
Multiply the parts: 2 × 0.1 = 0.2
Doing b), you get
4/8 = 0.5
10^-5 / 10^-6 = 10
Multiply the parts: 0.5 × 10 = 5
Conclusion:
The smaller number, 8 × 10^-6, is 0.2 of the larger number, 4 × 10^-5,
or, stated differently,
the larger number, 4 × 10^-5, is 5 times the smaller number, 8 × 10^-6
Let's see what she did.
She divided 8 by 4.
Then she divided 10^-5 by 10^-6. This is a mistake because she reversed the order of the powers of 10 before dividing.
Let's look at the choices:
Choice d) is correct because it has both divisions in the same order and comes to the correct conclusion that the larger number is 5 times greater than the smaller number.
Answer: d)
Part B)
8 × 10^-6 = 0.000008
4 × 10^-5 = 0.00004
Larger number: 4 × 10^-5

Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Hi! Im not sure about the other parts- But i know how to solve for the median!
Step-by-step explanation:
Ok to start off this is your data set.
64 53 60 60 56 58 51 55 60
Then after you place all these numbers in order from least to greatest.
51 53 55 56 58 60 60 60 54
Then you cross them out from side to side till you have the middle number or two numbers in the middle.
58,
So your median is 58!
(I know how to solve for the other ones but i think this is part a)
So i think its this-
Minimum: 51
Median : 53
Maximum: 64
First quartile: 55
Thirf Quartile: 60
( To solve for quartile tiles just say "I crossed out the numbers on each side starting from the median to the minimuk for the first quartile and then the Maximum for the Third quartile.)

P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Explanation:
T = tens digit of original number
U = units digit of original number
"units digit" is the same as "ones digit"
The original number is in the form 10T+U. For example, let's say that T = 3 is the tens digit and U = 1 is the units digit. This means 10T+U = 10*3+1 = 31 is the original number. Though in this example, the digits don't add to 12.
To make the digits add to 12, we have the equation T+U = 12. This solves to U = 12-T which we'll use later.
--------------------
The digits are reversed to get the new number 10U+T and this is 15 times the original tens digit, so
new number = 15*(original tens digit)
10U+T = 15T
from here we plug in U = 12-T which we found earlier. This effectively eliminates or gets rid of the U variable to leave us with T only
10U+T = 15T
10(12-T)+T = 15T ..... replace U with 12-T
which we can now solve for T
--------------------
10(12-T)+T = 15T
120-10T+T = 15T
-9T+120 = 15T
120 = 15T+9T ... adding 9T to both sides
120 = 24T
24T = 120
T = 120/24 .... divide both sides by 24
T = 5
The original tens digit is T = 5
The original units digit is U = 12-T = 12-5 = 7
So the original number is 10T+U = 10*5+7 = 57
Flipping the digits gets us 75 which is 15 times that of the original tens digit of 5. The original number has its digits add to 5+7 = 12. The answer has been confirmed.

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answers
Answer: 2
Step-by-step explanation: the figure has increased by 2 by x and y
Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
An example of dilation math is a square of side 5 units can be dilated to a square of side 15 units, but the shape of the square remains the same.
Dimensions of Object Q are as follows:
(3 1/3,1)
(3 1/3,2)
(1,1)
(1,2)
Dimensions of Object Q’ are as follows:
(6 2/3,2)
(6 2/3,4)
(2,2)
(2,4)
Dimensions of Object Q to Object Q’ are as follows:
(3 1/3,1) ⇒ (6 2/3,2)
(3 1/3,2) ⇒ (6 2/3,4)
(1,1) ⇒ (2,2)
(1,2) ⇒ (2,4)
Let’s consider each vertex one by one.
Therefore, the scale factor in this dilation is 2.
So, the correct option is Option (D) 2
