What is a coefficient?

A coefficient is a number that does not stand alone. For example, 3w means 3 times w, and "w" is a variable, so 3 is a coefficient.

How do we find the first term?

We can find the first term by putting the numbers from greatest to least. For example, if we had the numbers: 3x+7p+2 we would rearrange the series to this: 7p+3x+2. The number that comes first in the series would be the first term.

The average of the number given is $4.84.

The average can be calculated as follows:

Given X

X =$4.25+$6.71+$3.24+$5.06+$4.94

X =$24.2

= X ÷ n

= $24.2 ÷ 5

= $4.84

Hence, the average is $4.84

By evaluating a linear equation, we can see that 677.25 mL will be infused in 5.25 hours.

We know that the solution is being infused at a rate of 2.15 mL per minute.

So, t minutes after the infusion starts, the volume infused is given by the linear equation:

V(t) = 2.15mL*t

Here we want to see how many mL would infuse in 5.25 hours, to do that, we need to write that time in hours:

We know that one hour = 60 min, then:

5.25 h = 5.25*60 min = 315 min

Then the volume infused is:

V(315) = 2.15mL*315 = 677.25 mL

Answer:

16.11 (appx.)

Step-by-step explanation:

since l and m are parallel and a line intersects them, so we can say that the line is the transversal. from the figure we see that

7x + 12 = 12x - 28 [they are internal alternate angles and alternate angles are always equal to one another]

now, we can find the value of x from the equation

12x - 7x = 28 + 12

⇒ 5x = 40

⇒ x = 8

so the angle (7x+12)° is ((7*8)+12) = 68°

so (12x-28)° is also equal to 68° [cause of being alternate angles]

now, look at the figure,

angle (9y-77)° & (12x-28)° add upto a straight line as in 180°

and we know (12x-28)° = 68°

so now,

9y-77 = 68

⇒9y = 68+77

⇒9y = 145

⇒y = 16.11 (appx.)

A finite series is one that has a finite number of terms.

The number of pennies that Anya has is equal to 15.6 pennies.

The number of dimes that Anya has is equal to 2.8 dimes.

In order to solve this word problem, we would assign variables to the number of pennies and dimes, the total number of coins, and then translate the word problem into algebraic equation as follows:

Note: 1 penny is equal to 0.05 dollar and 1 dime is equal to 0.10 dollar.

Therefore, translating the word problem into an algebraic equation, we have the following;

p = 10 + 2d                                ......equation 1.

0.05p + 0.1d = 1.06                   .......equation 2.

Substituting equation 1 into equation 2, we have:

0.05(10 + 2d) + 0.1d = 1.06  

0.5 + 0.1d + 0.1d = 1.06

0.5 + 0.2d = 1.06

0.2d = 1.06 - 0.5

0.2d = 0.56

Dimes, d = 0.56/0.2

Dimes, d = 2.8 dimes.

For the number of pennies, we have:

p = 10 + 2d

p = 10 + 2(2.8)

p = 10 + 5.6

The true solution for 2 ln e^ ln (5x) = 2 ln (15) is x = 3.

Given,

2 ln e^ ln (5x) = 2 ln (15)

Apply log rule;

logₐ (aᵇ) = b

ln (e^ln (5x)) = ln (5x)

2 ln (5x) = 2 ln (15)

Divide both sides by 2;

2 ln (5x) / 2 = 2 ln (15)/ 2

ln (5x) = ln (15)

For ln (5x) = ln (15), solve for 5x = 15;

That is,

5x = 15

Then,

x = 15/5

So,

x = 3

Check this by substituting it to 2 ln (5x) = 2 ln (15);

x = 3

2 ln (5 × 3) = 2 ln (15)

x = 3 makes this true.

The symbol denotating two objects are parallel is a vertical double line.

A plane can be named by a capital letter (often written in script), or by the letters naming three non-collinear points in the plane.

The notation for a line segment is a bar placed above the endpoints of the line segment.

Domain, the set of possible x- coordinates:

Range, the set of possible y- coordinates:

Both end points are represented by arrows directed to left and right, it means both ends are indefinite but lines are parallel to the x-axis.

Answer:

1.  Domain:  [-2, 6]

   Range:  [-3, 7]

2. Domain:  (-∞, ∞)

    Range:  [1, 5]

Step-by-step explanation:

Definitions

Note:  Assume that each square on the given graphs is 1 unit.

The domain of the function is restricted since the curve has two distince endpoints.  As each endpoint is marked by a closed circle, the x-value of the endpoints is included in the domain.

The function has a maximum point at (-1, 7) and a minimum point at (6, -3).

Therefore, the range of the function is restricted.

As there are arrows at both endpoints of the function, and the function is continuous between the arrowheads, the domain is unrestricted.

The maximum y-value is y = 5.  When x < 1, the line continues indefinitely at y = 5.

The minimum value is y = 1.  When x > 1, the line continues indefinitely at y = 1.

Therefore, the range of the function is restricted.

The vertex of the graph of the parabola is at the point (-1, -6)

We know that for any parabola with a vertex at the point (h, k) and a leading coefficient a, can be written in vertex form as:

y = a*(x - h)^2 + k

In this case the parabola is:

f(x) = (-1)*(x + 1)^2 - 6

Comparing this with the general form, we can see that:

h = -1

k = -6
