Answers

Answer 1

Answer:

f(- 2) = 14

Find the next two terms in each sequence. Write a formula for the n th term. Identify each formula as explicit or recursive. 1,8,27,64,125, ......

Answers

The formula for finding any term of the given sequnce is [tex]a_{n}[/tex]  = n^3.

According to the given question.

We have a sequence

1, 8, 27, 64, 125

As we know that, a sequence or number pattern is an ordered set of numbers or diagrams that follow a rule.

The above of given sequence 1, 8, 27, 64, 125 is following a rule i.e each term is the cube of its number of term.

Here,

The first term is 1, so the cube of 1 is 1.

The second term is 8, so the cube of 2 is 8.

So, the nth term of the given sequnce is n^3.

Therefore, the formula for finding any term of the given sequnce is given by

[tex]a_{n}[/tex]  = n^3

Where, n = 1, 2, 3, 4...

So, for n = 1

The first term will be 1.

for n = 2

The second term will be 8

for n= 3

The fourth term will be 64.

Hence, the formula for finding any term of the given sequnce is [tex]a_{n}[/tex]  = n^3.

what does SAS stand for? what does it have to do with similar triangles?

Answers

Answer: SAS stands for side angle side and it means triangles are congruent by having the same side, angle, and side

Explanation: Let's say, two triangles both have the same angle, say 90 degrees. They also share two side lengths. Both triangles have a side length of 9 and another side length of 8.

The two triangles, sharing all these properties, must be congruent. This congruency is proven by SAS.

However, you must not get confused with other ways to prove congruency like ASA (Angle-Side-Angle)

What are comparing numbers?

The process of defining similarities between two numbers and determining which number is greater, smaller, or equal to the other number is known as comparing numbers.

Here we will compare the numbers by using counting.

We know that a number with more digits is typically greater than one with fewer.

i) The population of Birmingham is about 10 times as big as the population of Halifax because the population of Birmingham is 9,00,000 is greater than Halifax's 90,000 by 10.

ii) The population of London is about 1000 times as big as the population of Longton. Because the population of London has three more zero digits than the population of Longton.

what is the product of (x+6)(8x+7)

Answers

Answer: 8x^2 + 55x + 42

Step-by-step explanation:

(x+6)(8x+7)=

(8x*x)+(7x)+(6*8x)+(6*7)=

8x^2 + 7x + 48x + 42=8x^2 + 55x + 42

(x+6)(8x+7)
First, you multiple the x in the first parentheses by 8x and 7.
If this was in the format of distributive, it would look as following
x(8x+7)
So then you’d do
(x*8x) and (x*7) which would be
8x^2+7x
Next, you would multiply the 6 in the first parentheses with the two variables/numbers in the second parentheses as follows
6(8x+7)
(6*8x)(6*7)
48x+42
Combine the two separate equations.
8x^2+7x+48x+42
Combine like terms.
8x^2+55x+42
And there you go. That’s the product.

A die is rolled. Find the probability of the outcome. P( greater than 1 )

Answers

The probability of getting a number greater than 1 is 5/6

What is the formula of Probability?

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.

The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.

Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.

Therefore, probability P of getting a number greater than 1 is:

P = 5/6

Hence, the probability of getting a number greater than 1 is 5/6

What is the slope of the line that passes through the points (1, -7) and (−2,−7)?

Answers

The slope of the line is 0 since the y-value doesn't change, meaning it is a horizontal line.

Answer:

Slope ⇒ 0

Step-by-step explanation:

The formula to find the slope of a line is:

[tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex]

We can use the given two coordinates of the line to find the slope.

( 1, -7 ) ⇒ ( x₁, y₁ )

( -2, -7 ) ⇒ ( x₂, y₂ )

Let us solve this now.

[tex]m = \frac{y_1-y_2}{x_1-x_2}\\\\m = \frac{-7 -(-7)}{1-(-2)}\\\\m = \frac{0}{3}\\\\m=0[/tex]

Determine whether the events are independent or dependent. Then find the probability. You roll two dice and get a 5 each time.

Answers

The events are independent. The probability of getting 5 each dice after rolling the dice 2 times is 1/36.

As we are rolling two different die simultaneously, the events are independent.

The probability of getting a 5 in the first die = 1/6

The probability of getting a 5 in the second die = 1/6

Hence, as the events are independent, we can write :-

The probability of getting 5 each dice after rolling the dice 2 times =

probability of getting a 5 in the first die * probability of getting a 5 in the second die = (1/6)*(1/6) = 1/36

Describe the effect of a dilation on the length of a line segment.

Answers

The scale factor determines whether line segment dilation is longer or shorter.

What is dilation?Dilation is a transformation that allows you to resize an object. Dilation is a technique for making objects larger or smaller. This transformation yields an image that is identical to the original shape. However, there is a size difference in the shape.

The effect of dilation on the length of a line segment:

A line segment dilation is longer or shorter in the ratio given by the scale factor. If the scale factor is greater than one (k > 1), the image will be larger than the pre-image, making the image's segments (sides) longer than the pre-corresponding image's sides (an enlargement).

What is equation of a straight line?

Equation of a straight line is the equation of the form

y = mx + c

y and x are the unknown variables

m is the slope

c is the intercept in the y axis

The equation given in the problem is a special type which is a vertical line

How to write the equation of a vertical line

A vertical line has no intercept on the y axis hence c =0/ This reduces the equation of a straight line to

y = mx + c

at c = 0 we have:

y = mx + 0

y = mx

The slope of the vertical line is undefined. From first principles we have that slope is

m = change in y / change in x

for a line to be vertical the change in x is at the lowest absolute value and the smallest absolute number is zero. note negative number is not inclusive.

Therefore the slope at change in x = 0 represents a vertical line which is

m = change in y / change in x

m = change in y / 0

m = undefined

so y = undefined

check using calculator any number divided by zero gives error which is defined mathematically to be undefined,

We can conclude that the relationship between y and x from the graph is undefined.
