4 term in the sequence 3,9,15,21
The nth term in the sequence 3,9,15,21 will be 3 + 6(n - 1).
What is a sequence?It should be noted that a sequence simply means the order in which a particular thing happens or takes place.
From the information, four term in the sequence are given as 3,9,15,21 and we want to find the nth term. It should be noted that this is an arithmetic sequence.
The formula is illustrated as:
= a + (n - 1)d
where a = first term = 3
common difference = 9 - 3 = 6
The nth term will be:
= 3 + (n - 1)6
= 3 + 6(n - 1).

ANSWER
Step-by-step explanation:
if x= 6 and y= -4, evaluate: 3x + x/y - y^2
we will just substitute for the values
3(6) + 6/-4 - (-4)²
=18 + 6/-4 - (16)
=18 + 6/-4 - 16

A. -2x +4
B. 2x+ 4
C. Y= -7/6x + 3
D. Y= 1/2x +4
The equation for the linear model in the scatter plot obtained by choosing
the two points closest to the line is y = - 2x + 4
How to find the equation for a linear model?The equation for the linear model in the scatter plot obtained by choosing
the two points closest to the line can be solved as follows:
The two point closest to the line are as follows:
(2, 0)(1, 2)
Using the linear equation,
y = mx + b
where
m = slopeb = y-interceptHence,
m = 2 - 0 / 1 - 2
m = 2 / - 1
m = -2
Therefore, the y-intercept using (2, 0) will be as follows:
0 = -2(2) + b
b = 4
Hence, the equation for the linear model is y = - 2x + 4

TRIANGLE
A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon.
Each triangle has three sides and three angles, with some of the angles being the same.
In the case of a right triangle, the side opposite the right angle is known as the hypotenuse, while the other two sides are known as the legs.
Trilateral Relationship of Triangle
A trilateral is a shape with three sides in geometry. 'Of trilateral figures, an equilateral triangle is one with three equal sides, an isosceles triangle is one with two equal sides, and a scalene triangle is one with three unequal sides.'
Triangle Inequality
The triangle inequality asserts that the sum of the lengths of any two sides of a triangle must be larger than or equal to the length of the remaining side in mathematics.
The condition of the triangle's sides
According to the triangle inequality, the lengths of any two triangle sides must be more than or equal to the length of the third side. Only a degenerate triangle with collinear vertices can have that total equal to the length of the third side.
If and only if the side lengths satisfy the triangle inequality, a triangle with three given positive side lengths exists.

20% of a saline solution was mixed into saline solution with a concentration of 48% saline. How much of each solution be mixed together to obtain a solution of 8 milliliters with a 32% saline concentration
Answer:
Below in bold.
Step-by-step explanation:
Let x be the amount of 20% saline solution then the amount of 48% will
8 - x milliliters.
So,
0.20x + 0.48(8 - x) = 0.32* 8
0.20x + 3.84 - 0.48x = 2.56
-0.28x = -1.28
x = -1.28/-0.28
= 4.57 milliliters.
8 - x = 3.43 milliliters
The answer is:
4.57 milliliters of 20% solution and 3.43 milliliters of the 48% solution.

A card is drawn randomly from a standard 52-card deck. then the probabilities are a) 1/13 b) 3/13 and c) 10/13
There are four 3's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 3. This means that the probability will be:
p = 4/52
p= 1/13
b.
For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:
4*3 =12
The total possible cards are, still, 52, so, the probability will be
p= 12/52
p=3/13
c.
We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face card its:
p=52/52
p=1
so
p( the card is a face card ) + p( the card is not a face card) =1
but, we know that
p( the card is a face card ) =3/13
so
p( the card is not a face card) =1- 3/13
= 10/13

Before the drawbridge starts to open, the horizontal component of the friction force f⃗ is zero (0)
The horizontal component of the friction force is the counter force that must overcome the friction force for a body to slide or move.
When the dancer is standing still on the drawbridge, the only force on the dances is the normal force exerted by the bridge. Thus, the horizontal frictional force acting on the dancer

Just combined the like terms and got the answer!

12 - 10 - 2 = 0
90 + 70 = 160
Put them "as an equation": 10x + 160 = 360
Get rid of what's surrounding the x, so subtract 160 from both sides.

This is further explained below.
What is the rational exponent. ?Exponents are said to be rational if they are able to be represented in the form of p/q, where the value of q is less than 0.
The notation for rational exponents is often written as xm/n, where x represents the base (a positive integer) and m/n is the rational exponent. Exponents may also be represented as xmn=nxm x m n = x m n.
This is another way to express rational exponents.
Generally, the equation is mathematically given as
[tex](6\sqrt{x^5})^7[/tex]
By bearing this in mind, we can make this process easier.

What is the constant of variation of a direct variation model?
In the statement we find a linear model of the form y = r · x, which represents a linear variation model, that is, a model where the variable x is directly proportional to the variable y and r is the constant of variation.

33-2c+4=2c+14+c
Now, combine like terms.
33+4=37
2c+c=3c
Now you are left with:
37-2c=3c+14
Now, add 2c on both sides.

Answer:
78m^3
Step-by-step explanation:
basically you have to split it into two rectangles and add the volumes
so think of it like this (first picture)
- looking at the bigger rectangle (blue rectangle) the 6 and the 4 are there as hints to the smaller rectangle so just kind of disregard them
- basically the bottom length is 6 but the top length is 5 and this is because the bottom length includes the other rectangle (smaller/pink rectangle), meaning the extra length from the other rectangle (smaller/pink rectangle) is 1.
- then height is given as 4 and 5. the height of 4 is caused by the line stopping when it meets the pink/smaller rectangle, meaning that the height from the other rectangle (smaller/pink rectangle) is 1.
- so using the correct measurements, the height is 5, the length is 5, and the width is 3 so:
5 • 5 • 3 = 75
~ so as stated above from evaluating the different measurements and how the rectangles “intersect” or meet:
the height is 1, the width is 1, and the length is then given as 3 so:
1 • 1 • 3 = 3
so then 75 + 3 = 78
so the full volume is 78 m^3
