Find the 75th term of the arithmetic sequence -17, -13, -9....

Answers

Answer:

The 75th term of the arithmetic sequence -17, -13, -9.... is:

[tex]a_{75}=279[/tex]

Step-by-step explanation:

Given the sequence

[tex]-17, -13, -9....[/tex]

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]-13-\left(-17\right)=4,\:\quad \:-9-\left(-13\right)=4[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=4[/tex]

The first element of the sequence is:

[tex]a_1=-17[/tex]

now substitute [tex]d=4[/tex] and [tex]a_1=-17[/tex] in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=4\left(n-1\right)-17[/tex]

[tex]a_n=4n-21[/tex]

Now, substitute n = 75 in the [tex]a_n=4n-21[/tex] sequence to determine the 75th sequence

[tex]a_n=4n-21[/tex]

[tex]a_{75}=4\left(75\right)-21[/tex]

[tex]a_{75}=300-21[/tex]

[tex]a_{75}=279[/tex]

Therefore,  the 75th term of the arithmetic sequence -17, -13, -9.... is:

[tex]a_{75}=279[/tex]

36 - 7p = -7 ( p - 5)
a) No Solution
b) One Solution
c) Infinite Solutions

Answers

Answer:

a) No Solution

Step-by-step explanation:

36 - 7p = -7(p - 5)

36 - 7p = -7p + 35

1 - 7p = -7p

1 = 0p

so a) No Solution

Answer:

[tex]36 - 7p = - 7(p - 5) \\ 36 - 7p = - 7p - 7 \times - 5 \\36 - 7p = - 7p + 35 \\ p \: terms \: togather \\ - 7p + 7p = 35 - 36 \\ 0p = - 1 \\ here \: we \: \: have \: 0p \\ so \: no \: solution \\ option(a) \\ thank \: you[/tex]

What is 62% written as a decimal?

Answers

Answer:

62% = 0.62 in decimal form. Percent means 'per 100'. So, 62% means 62 per 100 or simply 62/100. If you divide 62 by 100, you'll get 0.62 (a decimal number).

The decimal of 62% is 0.62

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

We have to change 62% in decimal.

As, 62%

= 62/100

And, the number of zeroes in denominator decimals where to put the decimal.

so, 62/100

= 0.62

Do you agree with the statement that " cubic functions must have at least 1 x-intercept but not more than 3, whereas quadratic functions may or may not have x-intercepts

Answers

Answer:

Yes, I agree

Step-by-step explanation:

For the cubic function

A cubic function is represented as:

[tex]f(x)=ax^3+bx^2+cx+d[/tex]

A cubic function may have 1, 2 or 3 x intercepts. This is shown below

For 3 x intercepts

[tex]y = x^3 - x[/tex]

Equate y to 0

[tex]x^3 - x = 0[/tex]

Expand

[tex]x(x^2 - 1) = 0[/tex]

Express [tex]x^2 - 1[/tex] as difference of two squares

[tex]x(x - 1)(x +1 ) = 0[/tex]

x = 0 or 1 or -1

For 2 x intercepts

[tex]y = x^3 - x[/tex]

[tex]y =(x-5)^2)(x+7)[/tex]

Equate y to 0

[tex](x-5)^2(x+7) = 0[/tex]

Expand

[tex](x-5)(x-5)(x+7) = 0[/tex]

x= 5 or x = -7

For 1 x intercept

[tex]y = x^3[/tex]

Equate y to 0

[tex]x^3 = 0[/tex]

Take cube roots of both sides

[tex]x = 0[/tex]

It has been shown above that a cubic function may have 1, 2 or 3.

So, I agree to the statement

For the quadratic function

A quadratic function will not have any x intercept when the function can not be factorized;

E.g.

[tex]y = x^2 + x + 17[/tex]

The above function has no x intercept.

A quadratic function will have at least 1 x intercept when the function can be factorized;

E.g.

[tex]y = x^2- 6x + 9[/tex]

Equate y to 0

[tex]x^2- 6x + 9 = 0[/tex]

Expand

[tex]x^2 - 3x - 3x + 9 = 0[/tex]

[tex](x - 3)(x-3) = 0[/tex]

[tex]x = 3[/tex]

We've shown that a quadratic may have no x intercept, and it may also have x intercept(s)

Hence, I agree to both statement

I'll focus on problem 19 and problem 22

============================================================

Problem 19

Answers:

x = 87x+15 = 102

-------------------------------

Explanation:

The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.

Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.

x+15 = 102

x = 102-15

x = 87

Which leads to

x+15 = 87+15 = 102

============================================================

Problem 22

Answer: y = 27

-------------------------------

Explanation:

We have a pair of alternate exterior angles. They are congruent due to the parallel lines.

Let's solve for y.

7y-55 = 3y+53

7y - 3y = 53+55

4y = 108

y = 108/4

y = 27

Step-by-step explanation:

[tex] \tt{30.16 = 17.56 + 5x} [/tex]

Swap the sides of the equation :

⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ [tex] \tt{5x = 12.6}[/tex]

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

Which of the following is closest to the distance of the length when the bicycle wheel
makes 1 revolution?
A7 inches
B 25 inches
C34 inches
D69 inches


Can anyone help me!!

Answers

Answer: (21.75 / 2) * 2 * pi = 68.42...in, answer D.

Explanation: one revolution from a wheel will be a 360 degree rotation, meaning that if you had laid your finger on the outside of the wheel as it made its full rotation, your finger would have touched the entire circumference of the wheel. Thus, we can represent the length of 1 revolution as the circumference. Thus we take the diameter, and divide it by 2 to get the radius. Then we simply multiply by 2 * pi * r (r = radius). This is the formula for the circumference of a circle.
