Answer:

The third from the top does not belong with the others.

Step-by-step explanation:

With the exception of the 3rd quotient, the expressions all involve powers of the same base.  There is an exponent property that can be used in such a situation:

[tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

but the base, a, must be the same in both parts of the quotient!

The equation of the line in the attached graph in slope intercept form is written as

The slope, m of the linear function is calculated using the points on the graph (1, -4) and  (2, -10)

m = (y₀ - y₁) / (x₀ - x₁)

plugging in the values and evaluating

m = (-10 + 4) / (2 - 1)

m = (-6) / (1)

m = -6

equation passing through point (2, -10), using the point slope formula

(y - y₁) = m (x - x₁)

y - (-10) = -6(x - 2)

y + 10 = -6x + 12

rearranging the equation

y = -6x + 12 - 10

y = -6x + 2

The equation of the line in slope intercept form is written as y = -6x + 2

scalene acute triangle

Step-by-step explanation:

By looking at the side lengths, we can see that all of them are different, meaning the triangle is scalene. Next, we can notice that all of the angles are less than 90 degrees, meaning the triangle is acute. Putting this together, we get the triangle is a scalene acute triangle.

Step-by-step explanation:

The inverse of the logarithmic function f x log9x is f-1(x)=9^x.

The inverse of a logarithmic function is the exponential function. To find the inverse of the logarithmic function f x log9x, we can use the following equation: f-1(x)=9^x. This equation states that the inverse of the logarithmic function f x log9x is the exponential function f-1(x)=9^x.

The inverse of the logarithmic function f x log9x is f-1(x)=9^x, which is the exponential function.This means that for any value of x, the inverse of the logarithmic function f x log9x is equal to 9 raised to the power of x. For example, if x=2, then the inverse of the logarithmic function f x log9x is 9^2, or 81. Similarly, if x=3, then the inverse of the logarithmic function f x log9x is 9^3, or 729. In general, the inverse of the logarithmic function f x log9x is 9 raised to the power of x, for any value of x.

Step-by-step explanation:

GIVEN :-

A quadratic function is represented by the graph in which :-

TO FIND :-

GENERAL CONCEPT USED IN THIS QUESTION :-

A quadratic function has 2 forms :-

SOLUTION :-

The quadratic function in the graph intersects x-axis at two points (-3 , 0) & (1 , 0). But there are infinite parabolas which also intersect the same two points. And those parabolas have their unique quadratic function.

To find the unique quadratic function , you need to use three points on the

curve so that you can form 3 equations & solve them.

Using the General form of quadratic function , substitute the known values for x & y.

Let the three points be -

Substitute (-3 , 0) in general form of function -

[tex]0 = a(-3)^2 + b(-3) + c[/tex]

[tex]=> 9a-3b+c = 0[/tex]  (eqn.1)

Substitute (1 , 0) in general form of function -

[tex]0 = a(1)^2 + b(1) + c[/tex]

[tex]=> a + b +c =0[/tex]  (eqn.2)

Substitute (0 , -1.5) in general form of function -

[tex]-1.5 = a(0)^2 + b(0) + c[/tex]

[tex]=> c = -1.5[/tex]

Substitute c = -1.5 in -

1) eqn.1 → [tex]9a - 3b - 1.5 = 0[/tex]

[tex]=> 9a - 3b = 1.5[/tex]  

[tex]=> 3(3a-b) = 1.5[/tex]

[tex]=> 3a-b = 0.5[/tex]  (eqn.4)

2) eqn.2 → [tex]a+b-1.5=0[/tex]

[tex]=> a+b=1.5[/tex] (eqn.5)

Add eqn.4 & eqn.5 to get the value of 'a'.

[tex](3a-b)+(a+b) = 0.5+1.5[/tex]

[tex]=> 4a = 2[/tex]

[tex]=> a = \frac{2}{4} = \frac{1}{2} = 0.5[/tex]

Substitute a = 0.5 in eqn.5 -

[tex]0.5 + b = 1.5[/tex]

[tex]=> b = 1.5 - 0.5 = 1[/tex]

Now, rewrite the function in general form by putting the values of 'a' , 'b' & 'c'.

[tex]f(x) = (0.5)x^2 + (1)x - 1.5[/tex]

[tex]=> f(x) = 0.5(x^2 + 2x - 3)[/tex]

Factorise the quadratic polynomial.

[tex]=> f(x) = 0.5(x^2 + 3x - x - 3)[/tex]

[tex]=> f(x) = 0.5[x(x+3)-1(x+3)][/tex]

∴  [tex]f(x) = 0.5(x+3)(x-1)[/tex]

Another way to find the function is by taking any point on the curve & using the vertex of the parabola ; substitute the known values for x , y , h & k in  the Standard form of the function.

Let that point on the curve be (-3 , 0)

Vertex = (-1 , -2)

Substitute the values of x , y , h & k in Standard form of function.

[tex]0 = a[-3 - (-1)]^2 + (-2)[/tex]

[tex]=> 0 = 4a-2[/tex]

[tex]=> 4a = 2[/tex]

[tex]=> a = \frac{2}{4} = 0.5[/tex]

Now rewrite the Standard form of the function by putting the values of h , k & a.

[tex]f(x) = 0.5(x+1)^2-2[/tex]

Expand it.

[tex]=> f(x) = 0.5(x^2+2x+1)-2[/tex]

[tex]=> f(x) = 0.5x^2+x+0.5-2[/tex]

[tex]=>f(x) = 0.5x^2 + x- 1.5[/tex]

[tex]=>f(x) = 0.5(x^2 + 2x - 3)[/tex]

Factorising it will give the final answer.

∴  [tex]f(x) = 0.5(x+3)(x-1)[/tex]

The algebraic expression for the sequence 1, 10, 19, is given as a(n) = 1 + (n-1) 9.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression.

For the given sequence the common difference between two consecutive terms is 19 - 10 = 9.

The general form of the nth term of an arithmetic sequence is given as:

a(n) = a + (n-1) d

Since, the value of a = 1 and the common difference d =9, the resulting expression is:

a(n) = 1 + (n - 1) 9

Hence, the algebraic expression for the given sequence is a(n) = 1 + (n - 1) 9.

(a) Since cosθ = 7/12 and sinθ < 0, we can find the other four trigonometric functions as follows:

sinθ = √(1 - cos²θ) = √(1 - (7/12)²) = √(1 - 49/144) = -√(95/144)

tanθ = sinθ / cosθ = (-√(95/144)) / (7/12) = -4√(5/18)

cotθ = 1 / tanθ = -1 / (-4√(5/18)) = 1/(4√(5/18))

secθ = 1 / cosθ = 1 / (7/12) = 12/7

cscθ = 1 / sinθ = -1 / (-√(95/144)) = √(95/144)

(b) Since tanθ = 4/3 and θ is in Quadrant III, we can find the other five trigonometric functions as follows:

cosθ = √(1 / (tan²θ + 1)) = √(1 / (16/9 + 1)) = √(9 / 25) = 3/5

sinθ = cosθ * tanθ = (3/5) * (4/3) = 4/5

cotθ = 1 / tanθ = 1 / (4/3) = 3/4

secθ = 1 / cosθ = 1 / (3/5) = 5/3

cscθ = 1 / sinθ = 1 / (4/5) = 5/4

Trigonometric functions are a set of functions that relate the angles of a right triangle to the ratios of the sides of the triangle. The six most commonly used trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

The sine function, represented by sin, gives the ratio of the side opposite the angle to the hypotenuse. The cosine function, represented by cos, gives the ratio of the adjacent side to the hypotenuse. The tangent function, represented by tan, gives the ratio of the opposite side to the adjacent side.

The cotangent function, represented by cot, gives the ratio of the adjacent side to the opposite side. The secant function, represented by sec, gives the ratio of the hypotenuse to the adjacent side, and the cosecant function, represented by csc, gives the ratio of the hypotenuse to the opposite side.

On solving the provided question, we can say that the mean that 6 tests including the last test brian took.

A dataset's mean is the sum of all values divided by the total number of values, often known as the arithmetic mean (as opposed to the geometric mean). Often referred to as the "mean," this is the most often used measure of central tendency. Simply dividing the dataset's total number of values by the sum of all of those values yields this result. Both raw data and data that have been combined into frequency tables can be used for calculations. Average refers to a number's average. It is straightforward to calculate: Divide by how many digits there are after adding up all the digits. the total divided by the count.
