Step-by-step explanation:

The expression that is equivalent to negative three raised to the fourth power divided by negative three raised to the second power is (-3⁴) / (-3²)

Expression:

Expressions are the mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given,

Negative three raised to the fourth power divided by negative three raised to the second power.

Here we need to find the expression for this statement.

First, we have to divide the statement into two like,

"Negative three raised to the fourth power"

It can be written as,

=> (-3⁴)

And the for the next part,

"Negative three raised to the second power."

It can be written as,

=> (-3²)

Now we have to divide these two terms, the we get,

=> (-3⁴) / (-3²)

Therefore, the expression is (-3⁴) / (-3²).

The expression that represents the statement "four less than the product of 2 and a number g" is 2 g - 4.

We are given a statement:

four less than the product of 2 and a number g

We need to form an expression to represent that statement.

An expression is a combination of variables and constants by using the various operations of mathematics like addition, subtraction, division and multiplication.

So, first we will find the product of 2 and a number g.

This is:

2 × g = 2 g

Now, we will subtract 4 from the expression:

2 g - 4

Therefore, the expression that represents the given statement "four less than the product of 2 and a number g" is 2 g - 4.

The correct option is (C) 45°

The measure of angle ∠OCA = 45°.

A circle is a depiction with no sides or vertices.

It includes a radius as well as a center. The center is the point from which all other points just on circle are equidistant, and the distance between them equals the radius.

Let AC equal the tangent to the circle with center O.

OA ⊥ AC   ....(The tangent has always been perpendicular to the radius.)

As, it is given that ∠OAC = 90° and ΔOAC is isosceles triangle.

Thus, ∠O = ∠C = x (say)

Now, using the triangle's angle sum property. We have it,

90° + x + x= 180°

On simplification;

x = 45°

Thus, the value of angle ∠OCA is 45°.

The length of the pieces of wire include 23.5425 inches and 75.4565 inches.

Given the total length of wire is

X+Y=100

Y=100-X

Then we bend the two pieces into squares so that the sides of each square are X/4 and (100-X)/4. Therefore

(X/4)² + [(100-X)/4]² =400

X² +10000-200X +X² =6400

X²-100X+1800=0

Solving the equation

X = 76.4565 inches and X=23.5425 inches

Therefore, the length of the pieces of wire include 23.5425 inches and 75.4565 inches.

Hence, the equation of exponential function is represented by y = A(Bˣ)

The equation in exponential form

y = A(Bˣ)

Case 1 :

x =0 y = 0.02

0.02 =  A (B⁰)

A = 0.02

Case 2:

x = 1 y =0.04

0.04 =  0.02(B)

0.04 /0.02 = B

B = 2

Case 3 :

x = 2 y =0.08

0.08 = 0.02(2²)

0.08 = 0.08

Case 4 :

x = 3 y = 0.16

0.16 = 0.02(2³)

0.16 = 0.16

So, we have implemented the eqaution y = A(Bˣ)

We found the values of A & B, and also proved them in case 3 and case 4.

Hence, the equation of exponential function is represented by y = A(Bˣ)

the equation formula y=2/3x+5 is (3,-3).

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

based on the available facts;

You might be wondering how, but we can start with that 5 at the end, which denotes the y-intercept.

If 0 is used in place of x, then y=2/30+5y=5

We shall receive the first coordinate as a result, which is (0,5).

Let's then consider the slope, which is 2,3. As you may already be aware, the slope is also known as

rise/run

; what do they mean by that is that the first top number tells you how many units you go up and the second one how many units you go right or how many units you go down and go left.

Now, I know this may seem complicated but let's make it clear. Since we know one coordinate, which is

(0,5)

, from that point by knowing the slope we can find a second point; this point is 2 points above and 3 to the right, which tells us that −5+2

points above gives us −3 and 3 points on the right gives us a new coordinate:

(3,−3)

And since we now know two coordinates, that is enough to draw the line and have the graph.

Eli wishes to mix 0.5 gallons of a 10% acetic acid solution with a 35% solution to create a 15% acetic acid solution; thus, the calculation below must be done to calculate how many gallons of

5% solutions are required:

1 x 10 + 2 x 35 = 80

=> 80 ÷ 3 = 26.66

1x10 + 1x35 = 45

=>45÷ 2 = 2.5

1 x 10 + 0.5 x 35 = 27.5

=>27.5 ÷ 1.5 = 18.33

1 x 10 + 0.4 x 35 = 24

=>24 ÷ 1.4 = 17.14

1 x 10 + 0.2 x 35 =17

=> 17 / 1.2 = 14.16

1 x 10 + 0.3 x 35 = 20.5

=> 20.5/ 1.3 = 15.76

1 x 10 + 0.25 x 35 = 18.75

=> 18.75 / 1.25 = 15

1 / 2 = 0.5

0.25 / 2 = 0.125

The total value of the furniture she sold is $4400.

Let the remaining sales be represented by x.

She receives 10% of her first $900 in sales and 15% of the balance of her sale.

This will be:

(10% × $900) + (15% × x) = 750

90 + 0.15x = 750

Collect like terms

0.15x = 750 - 90

0.15x = 660

Divide

x = 660/0.15

Step-by-step explanation:

The triangle with vertices located at U(-5 , 5), K(-5 , -1), and L(1 , 2) has its centroid located at (-3 , 2).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) = U(-5 , 5)

Point 2(x2 , y2) = K(-5 , -1)

Point 3(x3 , y3) = L(1 , 2)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

C(x ,y) = [(-5 + -5 + 1)/3 , (5 + -1 + 2)/3]

C(x ,y) = (-9/3 , 6/3)
