Find two posiitive even consecutive integers such that the square of the smaller integer is 10 more than the larger integer.

Answers

Answer:

The two numbers are 4 and 6

Step-by-step explanation:

Suppose we have:

x=The smallest even integer

x+2=Next even integer

Recall even numbers occur every other integer.

The condition of the problem states the square of the smaller integer is 10 more than the longer integer:

[tex]x^2=10+x+2[/tex]

Rearranging and simplifying:

[tex]x^2-x-12=0[/tex]

Factoring:

[tex](x-4)(x+3)=0[/tex]

We have two solutions:

x=4, x=-3

Since the integers must be positive:

x=4

Next even integer= x+2=6

The two numbers are 4 and 6

In an arithmetic sequence, the first term is -8 and the sun of the first 20 term is 790. Find the common difference

Answers

Answer:

a=-8,s20=790

Step-by-step explanation:

s20=10[-16+19xd]

790/10=-16+19d

79+16=19d

85=19d

d=85/19=5

The common difference of the given arithmetic sequence is 5.

What is Arithmetic progression?

The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).

Natural number = 1,2,3,4,5,6,7,8...

Now it has the same difference between any two consecutive terms d =2-1 = 3-2

Given that,

First term a₁ = -8

Sum of first 20 terms = 790

Sum of the first N term is given by ;

⇒ N/2[2a + (n - 1)d]

So,

20/2[2(-8) + (20 - 1)d] = 790

10[-16 + 19d] = 790

19d - 16 = 79

19d = 95

d = 5

Hence "The common difference of the given arithmetic sequence is 5".

Point U is on line segment
TV
. Given TV=8 TU=2, determine the length uv
.

Answers

Answer:

Step-by-step explanation:

TV = VU + TU

Subsitute.

8 = VU + 2

-2 -2

VU = 6

A line segment is also a line but a line with finite length and fixed endpoints. The length of the line segment UV is 6 units.

What is a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

A line segment is also a line but a line with finite length and fixed endpoints.

Given that Point U is on the line segment TV. Therefore, it can be said that point U will lie between TV. Thus, we can write,

TV = TU + UV

As given the length of TV is 8 units, the length of TU is 2 units,

8 units = 2 units + UV

8 units - 2 units = UV

UV = 6 units

Hence, the length of the line segment UV is 6 units.

$2,000 each. Last Tuesday, she purchased 10 cars. Which of the following
functions correctly represents this situation in function notation?
f(x) = 10x + 200
f(x) = 200x + 2,000
f(x) = 2,000x + 10
f(x) = 2,000x + 200

Answers

Answer:

It would be 2,000x+200

Step-by-step explanation:

okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
