PLEASE HELP!log Subscript 3 (2x-7)= 4

Answers

Answer 1

Answer:

x = 44

Step-by-step explanation:

You can rewrite logarithm equations like so:

[tex]log_{b}(x) = y\\\\x = b^y[/tex]

A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.

In this case,

[tex]log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44[/tex]

Answers

Answer: 0.75n+1.75 ≤ 20 because you have to have the number of additional miles with the cost of $0.75 per mile but then you have to add the original first mile with a cost of $1.75. It has to be less than or equal to because you only have $20 to spend you can't spend more than that you have to spend that amount or less.

Answer:

casey has the faster rate

Step-by-step explanation:

first multiply jessicas race distance and time by 2

30 * 2

= 60    

5 * 2

= 10

we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )

now we are going to divide both of their times and distances by 5

casey

10/5

= 2

45/5

= 9

jessica

10/5

= 2

60/5

12

the step is to divide their times/distances once again but this time by 2

casey

2/1

= 1

9/2

= 4.5

jessica

2/1

= 1

12/2

= 6

and our answer is 4.5 or casey !

4.5 > 6

hope this helps you! :)

Answers

Answer:

[tex]\frac{1}{\sqrt{3} }[/tex]

Step-by-step explanation:

A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.

In the unit circle below, we can see that the line touches the unit circle at point [tex](\frac{\sqrt{3} }{2} ,\frac{1}{2})[/tex], therefore to find the tangent of theta, we use the formula:

[tex]tan\theta = \frac{y}{x} \\\\tan\theta=\frac{\frac{1}{2} }{\frac{\sqrt{3} }{2} } =\frac{1}{2}*\frac{2}{\sqrt{3} } \\\\tan\theta=\frac{1}{\sqrt{3} }[/tex]

Answers

Answer:

(n - 8n)(m+8n)

Step-by-step explanation:

x² - y² = (x - y)(x + y)

In this situation, the "x" = m and the "y" = 8n

So,

m² - 64n² = (n - 8n)(m+8n)

Answer:

(m - 8n)(m + 8n)

Step-by-step explanation:

m² - 64n² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

m² - 64n²

= m² - (8n)²

= (m - 8n)(m + 8n)

Write an equation for the amount of money, , that will be collected if boxes of chocolate bars are sold. Which is the independent variable and which is the dependent variable

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Let amount of money = C

If the number of chocolate bars sold = x

Let cost per chocolate bar = p, since cost per bar isn't stated

Amount of money that will be collected :

C(x) = P * x

The dependent variable is the Amount of money that will be collected as the amount of money depends on the number of chockate bars sold

The number of chocolate bars sold us the independent variable as it dictates the amout of money to be collected, hence it is the predictor variable.

Answers

Answer:

2,616.67cm³

Step-by-step explanation:

Find the diagram attached

volume of the cone = πr²h/3

r is the radius = 10cm

h is the height = 25cm

Substitute

V = 3.14(10)²*25/3

V = 314*25/3

V = 7850/3

V = 2,616.67cm³

Hence the volume of the cone to the nearest hundredth is 2,616.67cm³

The solution to which system of equations has an y-value of 0?

Step-by-step explanation:

The only system of equation (A) has a y-value of 0.

What are Systems of equations?

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

To find the solution with a y-value of 0, we need to substitute y=0 in each equation of the system and solve for x.

(A) x + 2y = -1

x + 2(0) = -1

x = -1

y = 3x + 3

y = 3(-1) + 3

y = 0

The solution to system A has a y-value of 0.

(B) 3x - y = 2

3x - 0 = 2

x = 2/3

x + 2y = -1

(2/3) + 2y = -1

2y = -1 - (2/3)

2y = -5/3

y = -5/6

The solution to system B does not have a y-value of 0.

(C) y = 3x + 3

y = 3x + 3 implies that y cannot be 0, so this system cannot have a solution with a y-value of 0.

(D) 2x + 3y = 0

2x + 3(0) = 0

2x = 0

x = 0

x + 2y = -1

0 + 2y = -1

y = -1/2

The solution to system D does not have a y-value of 0.

Therefore, the solution to system A has a y-value of 0.

The two dot plots show the number of miles ran by 14 students at the beginning and at the end of the school year compare each measure of the two dot plots

Answers

The two dot plots are missing, so i have attached it.

Answer:

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Step-by-step explanation:

From the attached image, we are told to compare the means for each plot to the nearest tenth.

Mean = Σx/n

Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;

(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133

Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles

Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143

Mean of miles run at the end of the school year = 143/14 = 10.2 miles

Thus;

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles
