Common Difference

The common difference in a geometric progression is the ratio between two successive terms.

The next two terms of this sequence will be 4th and 5th term.

The fourth term of this sequence is

A rectangular piece of cheese is 9 centimeters long is 5 centimeters wide. What is the perimeter

Answers

Solution:

We know that:

Perimeter of rectangle = 2L + 2B

Given:

L = 9 cmW = 5 cm

Substitute the values into the expression to find the perimeter.

Perimeter of rectangle = 2L + 2B=> 2(9) + 2(5)=> 18 + 10=> 28 cm

Answer: 28cm

Step-by-step explanation:

The perimeter formula for a rectangle = 2(l + w); where:

length = 9cm

width = 5cm

P = 2(l + w)

= 2(9 + 5)

= 18 + 10

= 28cm

Therefore, the perimeter of the cheese is 28cm

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

Answers

Answer:

Step-by-step explanation:

Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.

So (x+1) and (x-5) are root for the parabola.

y = (x+1)*(x-5)

That is the quadratic equation for Question B.

Back to A, the x-coordinate of vertex of this parabola is at x=2.

This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.

Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)

Answers

y = 3x + 2 = 3 * x + 2

point (10 ; 32) on the line ?

so here we can read : x = 10 and y = 32

if x = 10

then y has to be = 3 * 10 + 2 = 30 + 2 = 32

so yes - on the line

same reasoning for the rest

The ordered pairs which does not lie on the graph of the function are (8,13).

What is function?

Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.

The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.

How to find ordered pairs?

We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.

First ordered pair is (10,32)

32=3*10+2

32=30+2

32=32

It lies on graph.

Second ordered pair is (8,13)

12=3*8+2

12=24+2

12≠26

So it does not lie on graph of function y=3x+2.

Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).
