Find the domain of the logarithmic function and then graph the function. y= In (4x - 5) Find the domain of the function.
Answers
Domain = ( 5/4 , ∞)
Explanations:The logarithm function is given as:
y = ln (4x - 5)
the domain of the functions is a set of all the values of x that makes the function true (defined)
Note that the natural logarithm of a negative number is undefined. This means that the natural logarithm (ln) is only defined for positive numbers
This means that in y = ln (4x - 5), 4x -5 has to be greater than zero for the function to be defined.
Set 4x - 5 > 0
4x > 5
x > 5 / 4
Therefore, the domain of the function is a set of values greater than 5/4

Answer:
ima go with (A: 13, 19, 1)
Step-by-step explanation:
formula:
a+b>c = 13+19>7
a+c>b = 13+7>19
b+c>a = 7+9>13
The set 13, 19, 7 can be used to form a triangle.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
A triangle is formed when one side of triangle is greater than the difference of the two remaining sides, less than the sum of the two remaining sides.
If a, b and c are the sides of triangle,
Then
|a - b| < c < |a + b|
To find the set of measurement that could be used to form a triangle,
Use the options,
(a)
The given set is,
13, 19, 7
19 - 13 < 7 < 19 + 30
6 < 7 < 49
This set follows the condition of a triangle.

To start solving the system, Elena wrote:4x + y = 14x + 8y = 36And then she wrote:4x + y =14x + 8y = 36 --7y=-351. What were Elena's first two moves? What might be possible reasons for those moves?
Answers
Looking at the equations after Elena started solving the system, we can see that the second equation is different.
Each coefficient is 4 times greater the old coefficiets. That means equation B was multiplied by 4. She did this step to make both equations have the term 4x.
Then, in the next step, she subtracted the equations. Since both equations have 4x, subtracting the equations would cancel this term, then she can solve the result for y.
Therefore, in this step, she Subtracted the equations, this way she can cancel out the variable x.

14% of it was spent on bus fare i.e. 14/100×100= 14
Total 49% is spent on food and bus fare, when total budget is 100

Answer:
The rate of change of elevation tends to a constant value.
Explanation:
The average rate of change of e(x) on the interval [a, b] defined as
[tex]m_{\text{avg}}=\frac{e(b)-e(a)}{b-a}[/tex]which explicitly we can write as
[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}[/tex]Now, the question is, what happens to m_avg as we increase b while keeping a fixed?
As b becomes large then √b -10 becomes √b and b - a becomes b (since a is comparatively small); therefore, m_avg becomes
[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}\Rightarrow\frac{\sqrt[]{b}-\sqrt[]{a-10}}{b}\Rightarrow\frac{\sqrt[]{b}}{b}[/tex][tex]\Rightarrow m_{\text{avg}}=\frac{\sqrt[]{b}}{b}[/tex]which for any fixed value of b is a constant.
The same behaviour can be extrapolated by looking at the graph of e(x).
As can be seen from the graph, as x increases, the slope of the function becomes flatter and flatter, meaning it tends to be a constant. In other words, for large values of x, you can approximate the slope of the function by a straight line.

Answers
Ken will pay $ 871.25 for these items
Explanation
to find the total cost we need add the cost of the blocks to the cost of the total boards, so
Step 1
find the total cost of the blocks
a) when having the cost per unit and the amount, we just need to do a multiplication, so
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the blocks= 7.97}\frac{\text{ \$}}{block}*25\text{ Blocks} \\ tota\text{l cost of the blocks= \$ 199.25} \end{gathered}[/tex]Step 2
now, the total cost of the boards:
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the boards= 14}\frac{\text{ \$}}{board}*4\text{8 boards} \\ tota\text{l cost of the boards= \$ 672} \end{gathered}[/tex]Step 3
finally, add the costs to find the total
[tex]\begin{gathered} total\text{ cost= \$199.25+672} \\ total\text{ cost= 871.25} \end{gathered}[/tex]therefore, Ken will pay $ 871.25 for these items

Answers
We have a game like the one described in the question and we have to calculate the expected payoff, which is equal to the sum of the possible outcomes weighted by the probability of that outcome.
In this case we have two outcomes:
1) We get an odd number and we win $26 (W=26).
2) We get an even number and we get $0 (W=0).
To calculate the probabilities of each oucome we have to know the proportion of odd an even numbers in the list of 1 to 50. We have a total of 50 numbers, rom which 25 are odd numbers and 25 are even numbers, so the probability of each outcome can be calculated as the relative frequency of each category:
[tex]\begin{gathered} P_1=\text{ number of odds / total numbers}=\frac{25}{50}=0.5 \\ P_2=\text{ number of evens / total numbers}=\frac{25}{50}=0.5 \end{gathered}[/tex]Then, we can calculate the expected payoff as:

By using free body diagrams and trigonometric relations, the normal force of the block of iron has a magnitude of 352.579 newtons.
What is the normal force of the block of iron?
In accordance with the third Newton's law, normal forces (N), in newtons, are reactive forces as the result of the contact of the iron mass with the ground of the incline, that is to say, the normal force is the reaction of the weight of the iron mass (W), in newtons. If the iron mass is at rest, then we find the following free body diagram of the ground-mass system and its related geometric system.
Since the free body diagram represents a three force system, then the magnitude of the normal force is found by trigonometric relations:
N = W · cos 26°
N = (40 kg) · (9.807 m / s²) · cos 26°
N = 352.579 N

nealmiyasmith20, this is the solution:
-2× + 5y= -1
3× + 2y= 11
___________
Step 1: Isolating x on the first equation:
-2× + 5y= -1
-2x = - 1 - 5y
Dividing by -2 at both sides:
-2x/-2 = -1/-2 - 5y/-2
x = 1/2 + 5y/2
______________________
Step 2: Substituting x and solving for y on the second equation:
3× + 2y = 11
3 ( 1/2 + 5y/2) + 2y = 11
3/2 + 15y/2 + 2y = 11
19y/2 = 11 -3/2
19y/2 = 19/2
Multiplying by 2/19 at boths sides:
19y/2 *2/19 = 19/2 * 2/19
y = 1
___________________
Step 3: Substituting y and solving for x on the first equation:
-2× + 5y = -1
-2x + 5 * 1 = -1
-2x + 5 = -1
-2x = -1 - 5
-2x = -6
Dividing by -2 at both sides:
-2x/-2 = -6/-2
x = 3
Step 4: Proving that x = 3 and y = 1 are correct on the second equation:
3× + 2y = 11
3 * 3 + 2 * 1 = 11
9 + 2 = 11
11 = 11
We proved that x = 3 and y = 1 are correct
