Write an
explicit formula for
an,
the nth
term of the sequence 39, 41, 43, ....
Answer:
2n + 37.
Step-by-step explanation:
an = a1 + d(n - 1)
Here a1 = 39 and d = 2
an = 39 + 2(n - 1)
= 39 + 2n - 2
= 2n + 37.

Write the Quadratic Formula for the quadratic equation.
Answer:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
Step-by-step explanation:
Hello!
Let's start with the given equation and work our way towards x.
Solve for x[tex]ax^2 + bx + c = 0[/tex]Divide both sides by a
[tex]a(x^2 + \frac bax + \frac ca) = 0[/tex] [tex]x^2 + \frac bax + \frac ca = 0[/tex]Move c/a to the other side
[tex]x^2 + \frac bax = -\frac ca[/tex]At the step, we have to use the Completing the Square method.
[tex]x^2 + \frac bax + (\frac{b}{2a})^2 = -\frac ca + (\frac b{2a})^2[/tex][tex]x^2 + \frac bax + \frac{b^2}{4a^2} = -\frac ca + \frac {b^2}{4a^2}[/tex][tex](x + \frac b{2a})^2= -\frac ca + \frac{b^2}{4a^2}[/tex]Multiply -c/a by 4a and add the two fractions
[tex](x + \frac b{2a})^2= \frac{b^2 - 4ac}{4a^2}[/tex]Square Root both sides
[tex]\sqrt{(x + \frac b{2a})^2}= \sqrt{\frac{b^2 - 4ac}{4a^2}}[/tex][tex]x + \frac b{2a} = \pm\frac{\sqrt{b^2 - 4ac}}{2a}}[/tex]Subtract b/2a
[tex]x = \pm \frac{ \sqrt{b^2 - 4ac}}{2a} - \frac b{2a}[/tex][tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]And that's the derivation of the Quadratic Formula.

Mark think of a number mark doubles it and add 2.9 to get answer of 30.6 form an equation with x from the information
Answer:
2x + 2.9 = 30.6
Step-by-step explanation:
We are to represent the unknown number that Mark thinks of with x
If Mark doubles this unknown number, he multiplies it by 2 and the unknown number becomes - 2x
He then adds 2.9
The equation becomes 2x + 2.9
The answer of the above equation is 30.6
This gives : 2x + 2.9 = 30.6

A bookmark has an area of 21 square centimeters. Its perimeter is 20 centimeters. What are the dimensions of the bookmark?
Answer: The dimensions are 7cm and 3cm.
Step-by-step explanation:
The following equation can be deduced from the question
L × W = 21 ....... i
2L + 2W = 20 .......... ii
Divide equation ii through by 2
(2L + 2W = 20) / 2
L + W = 10 ....... iii
From equation iii
L = 10 - W ......... iv
Put equation iv into I
L × W = 21
(10 - W) × W = 21
10W - W² = 21
W² - 10W + 21 = 0
W² - 7W - 3W + 21 = 0
W(W - 7) - 3(W - 7) = 0
W - 3 = 0
W = 0+3
W = 3 centimeter
Since,
Length × Width = 21
Length = 21/3
Length = 7 centimeters
The dimensions are 7cm and 3cm.

Priscilla can make 2 bracelets in 16 minutes. At this rate, how many bracelets can she make in 64 minutes?
Answer:
8 bracelets.
Step-by-step explanation:
First, find out how long it'll take Priscilla to make on bracelet. It is given that she can make 2 bracelets in 16 minutes. Divide 16 with 2:
16/2 =8
Priscilla takes 8 minutes to make 1 bracelet. Divide 64 with 8 to find the amount of bracelets Priscila can make:
64/8 = 8
8 bracelets is your answer.
~
Given: Priscilla makes 2 bracelets in 16 minutes
To Attain: How many Bracelets she will make in 64 minutes?
⠀⠀⠀⠀⠀⠀__________________
Solution:
Firstly, We will divide the 16min with 2 to find the that how many time taken to make 1 bracelets. then we will multiply the rate with 64min to find how many bracelets she will make! Let's do it•
⠀⠀
[tex]:\implies\sf\dfrac{\cancel{16}^{8}}{\cancel{2_1}}[/tex]
⠀⠀
It will take 8 minutes to make one Bracelets.
⠀⠀
So, Let's find out that how many bracelets she will make in 64 minutes
⠀⠀
[tex]:\implies\sf\dfrac{\cancel{64}^{8}}{\cancel{8_1}}[/tex]
⠀⠀
[tex]\therefore \underline {\sf{Hence , \:She \: will \: make \: \pmb{8 \: bracelets }\: in \: 64 \: minutes. }}[/tex]

Please help I am so stuck
the angle of a quadrilateral are A.P and the common difference is 10°. find the angles.
help me plz
Step-by-step explanation:
So the Ap will be x,x+10,x+20,x+30
Sum of the angles of a quadrilateral is 360
x+x+10+x+20+x+30=360
4x+60=360
4x=300
x=75
So the angles are 75,85,95,105
