The sequence 38, 44, 50,.... is an arithmetic sequence

The explicit rule of the sequence is an = 32 + 6n

The sequence 38, 44, 50,.... is an arithmetic sequence with the following parameters:

First term, a1 = 38

Common difference, d = 6

The explicit rule is calculated as:

an = a1 + (n - 1) * d

This gives

an = 38 + (n - 1) * 6

Evaluate the product

an = 38 - 6 + 6n

This gives

an = 32 + 6n

Hence, the explicit rule of the sequence is an = 32 + 6n'

Step-by-step explanation:

part1

the mean value is

(87+100+94+79+92+100+95+83+89+99+100+91+89+95+100+93+96+83) / 18

Answer:

58.50

Step-by-step explanation:

Multiply 50 and .17 which equals 8.5 then add that to 50.

The amount of money in the account in December with a rate of 17% of the initial amount of $50 is $58.5.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A teenager puts $50 into an investment account in January.

Let, he deposited on first January.

If by December the balance in the account increases by 17%,

Let the amount by the 31 first of December will be

Then the amount will be given as

[tex]A = P (1 + \dfrac{r}{100})^t[/tex]

P = $50

r = 17%

t = 1

Then we have

[tex]\rm A = 50(1 + \dfrac{17}{100})^1\\\\A = 50(1 + 0.17)\\\\A = 50 * 1.17 \\\\A = 58.5[/tex]

Step-by-step explanation:

Answer: x = 52.1 degrees

Step-by-step explanation:

The tangent of an angle is the opposite side divided by the adjacent side.

Therefore, tan(x) = 45/35.

We can find thte value of x by doing the arc tangent of 45/35, which makes x about 52.1 degrees.

Answer:

It is 45.8° because it is a straight line so straight line is 180°.

Answer:

You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear.

An equation is considered linear, if it is in the form of. y = mx + b. where m is the slope of the equation, and b is the y-intercept.

First of all the shape of the graph is a straight line. Every linear graph is nothing more than a straight line so if there is any curves in it, it's not linear. The other way to tell is look at its equation.

Answer:

37°

Step-by-step explanation:

angles in a triangle add up to 180 degrees.

if two sides have the same length, an isosceles triangle is formed. the angles corresponding to the sides that have the same length are the same therefore, as FH = HG, ∠HFG = ∠FGH

180° = ∠HFG + ∠FGH + ∠FHG

= 106° + ∠HFG + ∠HFG

= 106° + 2* ∠HFG

subtract 106 from both sides to isolate the unknown and its coefficient

74° = 2*∠HFG

divide both sides by 2 to isolate the unknown

37° = ∠HFG = ∠FHG = w

Answer:

x=11

x=−5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  6*x+55-(x^2)=0

 -x2+6x+55  =0

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     -1

                     B   =    6

                     C   =   55

Accordingly,  B2  -  4AC   =

                    36 - (-220) =

                    256

Applying the quadratic formula :

              -6 ± √ 256

  x  =    ——————

                     -2

Can  √ 256 be simplified ?

Yes!   The prime factorization of  256   is

  2•2•2•2•2•2•2•2  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 256   =  √ 2•2•2•2•2•2•2•2   =2•2•2•2•√ 1   =

               ±  16 • √ 1   =

               ±  16

So now we are looking at:

          x  =  ( -6 ± 16) / -2

Two real solutions:

x =(-6+√256)/-2=3-8= -5.000

or:

x =(-6-√256)/-2=3+8= 11.000

Question one:
[tex]x-5 < -4[/tex]
[tex]-5+5=0[/tex]
[tex]-4+5=1[/tex]
[tex]x < 1[/tex]
[tex]\:\left(-\infty \:,\:1\right)[/tex]
