What are the coordinates of the point on the directed line segment from (-3, 5) to (−1,−7) that partitions the segment into a ratio of 3 to 1?
Someone help please I don’t know what to do tysm
Answer:
40
Step-by-step explanation:
Perimeter means add up all the sides
The top is 4+b, and b is 10, so the top and bottom are 14 each
The side is a which is 6 so
p=bottom+top+left side+right side
=14+14+6+6
=40
plzz someones help me plz I will mark brainlest diameter is 1 3/4
Answer:
The area of the circle is 2.41 in^2
Step-by-step explanation:
You are given the diameter, 1 3/4. This is a mixed fraction, so let's convert that into decimal.
1 3/4 = 7/4
7/4 = 1.74
Now, let's use the area of circle formula.
A = 1/4πd^2
A = 1/4 * π * 1.75^2
A ≈ 2.40528
Let's round the area to the nearest hundredth.
2.40528 = 2.41

A student says that every time they add an element to a set, the number of subsets doubles.
Is the student correct? Explain thoroughly
Answer:
Yes she is correct
Step-by-step explanation:
Suppose before we add and additional element x to a set A the number of subsets are n.
Now we can think of the subsets of the new set A union x as the subsets containing x and the subsets that are not containing x.
The subsets that are not containing x are exactly the former n subsets of A and the subsetes that are containing x is obtained by appending x to each of the n subsets. So we get another n subsets.
Therefore there are n + n =2n subsets which is double of the original subsets.
Therefore, there are n + n = 2n subsets which are doubled of the original subset.
SetsSets are the collection of well-defined elements. A set is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.
Ratio and proportionA ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given
Every time they add an element to a set, the number of subsets doubles.
How to define it?Let the number of sets be n
But every time they add an element to a set, the number of subsets doubles.
Then according to the condition,
n + n = 2n
Therefore, there are n + n = 2n subsets which are doubled of the original subset.

The perimeter of a rectangle is 82 meters. If the length of the rectangle is 20 meters more than the width
of the rectangle, find its length and width.
Answer:
30.5 meters
10.5 meters
Step-by-step explanation:
x = length
y = width
x = y + 20
2x + 2y = 82 (the perimeter of a rectangle)
using the first equation as substitute in the second equation we get
2×(y + 20) + 2y = 82
2y + 40 + 2y = 82
4y = 42
y = 42/4 = 21/2 = 10.5 meters
x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Find the area of the square whose side is [10 - 3x (-2)] cm.*
Step-by-step explanation:
Given that,
Side of the square = [10 – 3x(–2)] cmWe have to calculate the area of the square.
⠀⠀⠀⠀⠀★ Area of square = (Side)² ★
[tex] \dashrightarrow \quad \rm { Area = [10 - 3x(-2)]^2 \; cm^2} \\ [/tex]
[tex] \dashrightarrow \quad \rm { Area = [10 + 6x]^2 \; cm^2} \\ [/tex]
[tex] \dashrightarrow \quad \rm { Area = (10)^2 + (6x)^2 + 2(10 \times 6x) \; cm^2} \\ [/tex]
[tex] \dashrightarrow \quad \rm { Area = 100 + 36x^2 + 2(60x) \; cm^2} \\ [/tex]
[tex] \dashrightarrow \quad \underline{\boxed{\bf { Area = 100 + 36x^2 + 120x \; cm^2}}} \\ [/tex]
[tex]\rule{200}2[/tex]
Answer:
36x^2 + 120x + 100 cm^2.
Step-by-step explanation:
[10 - 3x (-2)]
= 10 + 6x
The area = (10 + 6x)^2
= (10 + 6x)(10 + 6x)
= 10*10 + 10*6x + 10*6x + 6x*6x
= 100 + 60x + 60x + 36x^2
= 100 + 120x + 36x^2.

A new popular midsize car has a retail price of $25,000. The midsize car's value M(t) is given by the exponential model M of t is equal to 25,000 times the quantity four fifths to the power of t where t represents the time in years. Identify the domain, in yearly intervals, that contains all the years the car's value is less than $1,000.

[14, ∞)
[15, ∞)
[16, ∞)
Answer:
Its C
Step-by-step explanation:
Just finished the homework and got it right
Using exponential functions, it is found that the correct option is given by: [15, ∞)
-------------------------
The exponential function given in this exercise is:
[tex]M(t) = 25000(\frac{4}{5})^t[/tex]
-------------------------
The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:
[tex]M(t) < 1000[/tex]
Thus, we have to solve the exponential inequality.
[tex]M(t) < 1000[/tex]
[tex]25000(\frac{4}{5})^t < 1000[/tex]
[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]
[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]

d. √16, 4.23_23, √18, 4 2/3
Step-by-step explanation:
There are a couple of different ways to compare these numbers. Maybe one of the most straightforward is to find the decimal equivalent, rounded to hundredths.
4.23_23 ≈ 4.23
4 2/3 ≈ 4.67
√18 ≈ 4.24
√16 = 4.00
These can be sorted least-to-greatest by putting the first number (4.23) between the last two (4.00, 4.24) and reading the new list last-to-first.
4.00, 4.23, 4.24, 4.67 ⇔ √16, 4.23..., √18, 4 2/3
_____
Additional comment
Another way to work this problem is to square the numbers not under a radical. 4.23...² ≈ 17.91 and (4 2/3)² ≈ 21.78. The ordering of the squares is the same as the ordering of their square roots.
16 < 17.91 < 18 < 21.78 ⇔ √16 < 4.23... < √18 < 4 2/3

Answer:
It's A
Step-by-step explanation:
Using process of elimination B is wrong because even though you get 37 and 36 it multiplies them because of a lack of addition symbol. C is also wrong because it would turn out to be 12 x 13 which is larger than C so that's not it. in D 3x4 is 12 but it's added to 9 not multiplied so that's wrong which leaves you with A which is 9(3 + 4) = 63 and 27 + 36 = 63
