Answer:
x = 3⁴
Step-by-step explanation:
You want the exponential form of log₃(x) = 4.
LogarithmIt can be helpful to remember that a logarithm is an exponent of the base of the logarithm.
log₃(x) = 4 ⇔ x = 3⁴
The exponential form is x = 3⁴.
Tom has 13 new magazines to read. Let M be the number of magazines he would have left to Read after reading R of them. Write an equation relating to M to R. Then graph your equation using the axis below
The equation that relates M to R is M = 13 - R
How to determine the equation that relates M to R?From the question, we have the following parameters:
Total number of new magazines = 13Number of magazines read = RNumber of magazines left = MThe total number of new magazines is the sum of the number of magazines read and the number of magazines left
This is represented as
Total number of new magazines = Number of magazines read + Number of magazines left
Substitute the known values in the above equation
13 = R +M
Make M the subject
M = 13 - R
Hence, the equation is M = 13 - R

The equation which describes Riya's graph is:
a). C(t) = -3t + 24.
We can easily find out the equation by concentrating on the axes.
For example,
Just look from the graph the value of C when t = 0.
We can conclude that C should be equal to 24 when t is equal to 0.
Now, let us put this value of t ( which is 0) in the equations one by one:
a). C(t) = -3t + 24
=> C(0) = -3 (0) + 24
=> C(0) = 24.
So, equation a). satisfies the given criteria.
Similarly, b) also qualifies but c) and d) are not equal to 24 when t = 0.
So, remove them.
Now, let's look at the value of t when C=0.
We can see that t should be equal to 8.
Let's put this value in equations,
a). 0 = -3t + 24
=> 3t = 24
=> t = 8.
Now, we can see that equation a). satisfies all the given conditions for the graph.

the quotient of 21 and a equals 30
The resulting value for the quotient of 21 and a equals 30 is 7/10.
Quotient of two numbersThe result of dividing two numbers is known as the quotient. Six divided by two results in the number three.
Latin's "how many times" is the meaning of the word "quotient." That is really logical. For instance, the quotient of a and b is a/b
Given the statement "the quotient of 21 and a equals 30", this can be written mathematically as;
21/a = 30
Cross multiply
30a = 21
Divide both sides by 30
30a/30 = 21/30
a = 21/30
a = 7/10
Hence the value of a from the equivalent expression is 7/10.

Given that ∠1 and ∠2 are right angles.
By the definition of right angles i.e. right angle is one that is exactly 90 degrees. It is precisely one-quarter of a circle. When a pie is divided into four equal pieces, the tip of each slice forms a straight angle.

there are 324 students in a college who have taken a course in calculus, 211 who have take a course in discrete mathematics, and 135 who have taken a course in both calculus and discrete mathematics. how many students at this college have taken a course in either calculus or discrete mathematics?
265 students at this college have taken a course in either calculus or discrete mathematics.
Let X = number of students who have taken a course in calculus
Y = number of students who have taken a course in discrete mathematics
To determine the number of students who have taken a course in calculus only, subtract 135 from 324.
Only X = X - X∩Y
Only X = 324 - 135
Only X = 189
To determine the number of students who have taken a course in discrete mathematics only, subtract 135 from 211.
Only Y = Y - X∩Y
Only Y = 211 - 135
Only Y = 76
To determine the number of students who have taken a course in either calculus or discrete mathematics, add 189 and 76.
either X or Y = only X + only Y
either X or Y = 189 + 76
either X or Y = 265

find x and y intercepts of x+4y=8
Answer: You could assume that X=8 and y=0
Step-by-step explanation:
Answer:
Solutions below.
Step-by-step explanation:
This Question involves the concept of intercepts of a graph.
InterceptsIntercepts of a graph are namely the x-intercept and y-intercept.
x-intercept is when y = 0. Example: (3,0)
y-intercept is when x = 0. Example: (0,9)
ApplicationWe are given the equation: x + 4y = 8
To find x-intercept, we can substitute y = 0 into the equation to obtain the value of x.
x + 4(0) = 8
x + 0 = 8
x = 8
Coordinates: (8, 0)
To fins y-intercept, we can substitute x = 0 into the equation to obtain the value of y.
0 + 4y = 8
4y = 8
y = 8 ÷ 4
y = 2
Coordinates: (0, 2)

Hello there. To solve this question, we'll have to remember some properties about trigonometric functions and the right triangle.
We want to find x such that:
[tex]\tan (x)=\sqrt[]{3}[/tex]We'll use the second right triangle to show what we want.
First, given a triangle:
We know that the hypotenuse will be:
[tex]\sqrt[]{x^2+y^2}[/tex]But most importantly, the tangent of the angles α and β can be calculated by only using the legs of the triangle: it is the ratio between the opposite side and the adjacent side to an angle.
[tex]\tan (\alpha)=\frac{y}{x}[/tex]and
[tex]\tan (\beta)=\frac{x}{y}[/tex]Now look at the triangle we have:
We can easily check that:
[tex]\sqrt[]{3}=\frac{\sqrt[]{3}}{1}[/tex]So it would be good to find something that relates the ratio between those two numbers: the tangent of 60º!!
Therefore, we have:
[tex]\tan (60^{\circ})=\frac{\sqrt[]{3}}{1}=\sqrt[]{3}[/tex]And the solution to x is:

Which table represents a linear function?
The table that represents a linear function is Table 1. Thus, the correct option is A.
What is a linear equation?A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.
Linear equation with two variables, when graphed on a cartesian plane with axes of those variables, give a straight line.
We know that, slope m= (y2-y1)/(x2-x1)
Table 1:
Put (x1, y1)=(1, 5) and (x2, y2)=(2, 9) in slope formula
That is, (9-5)/(2-1)
= 4
Similarly, the slope between last two points is (9-5)/(4-1)
=4
Table 2:
Put (x1, y1)=(1, -5) and (x2, y2)=(2, 10) in slope formula
That is, (10+5)/(2-1)
= 15
Similarly, slope between last two points (20+15)/(4-3)
=35
Hence, the table that represents a linear function is Table 1. Thus, the correct option is A.
