Answer:
4°C
Explanation:
Equation: y = -0.36x + 12.6
To find wind chill at 23 mi/hInsert x = 23Simplify
y = -0.36(23)+12.6
y = 4.32°C
y = 4°C (rounded to nearest degree)

Given the infinite series: [tex]\frac{1}{(1)(3)} +\frac{1}{(3)(5)}+\frac{1}{(5)(7)}+...[/tex]
a. Rewrite the series in sigma notation
b. Write an explicit formula for the nth partial sum
a) The infinite series in sigma notation is described by this expression:
[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex] (1)
b) The explicit formula for the n-th partial sum is represented by the following expression:
[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex] (2)
How to derive an expression for a monotonous series
An infinite series is monotonous when it is bounded, that is, when the limit of the infinite series exists. In this case, we have an evidence of monotony in the denominators of the terms of the given series. In two consecutive terms, the latter always have a denominator greater than the former.
a) The series in sigma notation is now described below:
[tex]y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}[/tex]
b) The explicit formula for the n-th partial sum is defined by the expression within the sum, which is now presented below:
[tex]y = \frac{1}{i\cdot (i+2)}[/tex], i ∈ [tex]\mathbb{N}[/tex]

7x+8=4x+4 please work this out and give your fraction an a improper fraction and simplest form
Answer:
x= -4/3
Step-by-step explanation:
Steps
7x +8 = 4X + 4
Subtract 8 from both sides
7x+ 8-8= 4x + 4-8
Simplify
7x=4x-4
Subtract 4x from both sides
7x-4x=4x-4-4x
Simplify
3X = -4
Divide both sides by 3
3X/3 = -4/3
Simplify
x= -4/3
Answer:
Step-by-step explanation:
Solution
7x+8=4x+4 Subtract 4x from both sides
7x - 4x + 8 = 4 Combine
3x + 8 = 4 Subtract 8 from both sides
3x + 8 - 8 = 4 - 8 Combine
3x = - 4 Divide by 3
3x/3 = -4/3
Answer: x = -4/3

Step-by-step explanation:
you have to combine -8 and 2 because they are like terms, but since -8 is being subtracted from -3k the minus sign and the negative sign basically combine to make a positive sign so it would make it -3k + 8 + 2 which gives you -3k + 10

The area of a rectangle is 20. The length is 5, and the width is the √x. What is the value of x? What is the width of the rectangle?
A. The value of x is 4. The width is 16.
B. The value of x is 16. The width is 4 or –4.
C. The value of x is 4. The width is 2.
D. The value of x is 16. The width is 4.
Answer:
D
Step-by-step explanation:
5([tex]\sqrt{x}[/tex]) = 20 Divide by 5
[tex]\sqrt{x}[/tex] = 4 Square both sides
x = 16
Widths can't be negative
Answer: D
Step-by-step explanation:
A = LW
[tex]\sqrt{x}[/tex] * 5 = 20
[tex](\sqrt{x} * 5)^{2} = 20^{2}[/tex] (square both sides)
x * 25 = 400
25x = 400
[tex]\frac{25x}{25} = \frac{400}{25}[/tex] (divide both sides by 25)
x = 16
[tex]\sqrt{16} = 4[/tex]
x = 16, and the width is 4.
A map's scale is 1 inch equals 50 miles. if new york city is 4 inches away from chelsea, ma, about how many miles is it from chelsea to new york city?
Answer:
200 miles
Step-by-step explanation:
Each inch represents 50 miles, so 4 times 1 inch will represent 4 times 50 miles.
4(1 in) ⇔ 4(50 mi)
4 in ⇔ 200 mi
It is about 200 miles from Chelsea to New York City according to the map.

Step-by-step explanation:
when you are on that level of math that you get this type of question - this is totally easy.
we get the extreme point(s) of a function by finding the zeros of the first derivative of the function.
f'(x) = 4x - 8
so,
0 = 4x - 8
8 = 4x
x = 2
to determine whether it is a minimum or a maximum, we have 2 choices :
the quick way for a quadratic (parabola) equation by looking at the factor of x² : is it >0, then the parabola opens up upwards, and the extreme point is therefore a minimum. if it is <0, then it opens downward, and the extreme point is a maximum.
in our case : 2 is larger than 0, therefore minimum.
or the formal way for any type of function : create the second derivative and see, if it is >0 (minimum) or <0 (maximum) for the extreme x.
in our case
f''(x) = 4
this is larger than 0 for all x, so the extreme point is a minimum.

A spinner with a yellow, blue, red, and green section is shown. The arrow is pointing at the yellow section. The fair spinner shown is spun 2 times. The set of possible outcomes are: S = {RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY} The number of yellows in the outcome is summarized in the table on the right. A 2-column table has 3 rows. The first column is labeled Yellow with entries 0, 1, 2. The second column is labeled Frequency with entries 9, 6, 1. Using the data from the theoretical probability table, what is the probability of the spinner landing only once on yellow in two spins? 0.0625 0.5625 0.375 1
The probability of the spinner landing only once on yellow in two spins is P = 0.375
How to get the probability?All the possible outcomes have the same probability, so, the probability that in two spins the spinner land only once in yellow is given by the quotient between the number of outcomes that have only one yellow and the total number of outcomes.
All the outcomes are:
{RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY}
16 in total.
The ones where the spinner lands only once on yellow are:
{RY, BY, YB, YG, GY, YR}
6 outcomes.
So the probability is:
P = 6/16 = 0.375

You can use the surface area formula for a right cone to find the surface area
of an oblique cone.
A. True
B. False
Answer:
False
Step-by-step explanation:
False. Both surface area cannot be find using the same formula.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Right cone is a cone where the axis of the cone is perpendicular to the base .
Whereas, oblique cone has the axis of cone not perpendicular to the base.
Base area would be same for both right and oblique cones.
But the lateral surface area will be different.
Hence the surface area will be different.
Hence the surface area formula for a right cone is not same to find the surface area of an oblique cone.

Step-by-step explanation:
What are the period, phase shift, and vertical shift of y = csc[3(x 4)] 6?
The period of the given function is 2π/3, the phase shift is 4, and the vertical shift is 6 units.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a trigonometric function:
y = csc[3(x+ 4)]+ 6
Every each revolution of 2π the function repeats the same value for every x.
The period of the original function is 2π
For the given function plug 2π
y = csc[3(x+ 4)+2π]+ 6
y = csc[3(x+ 2π/3+4)]+ 6
The period of the function will be 2π/3
From the function, the phase shift = 4
And vertical shift = 6
Thus, the period of the given function is 2π/3, the phase shift is 4, and the vertical shift is 6 units.
