Answer:

A perfect square is a shape with for 90 degree angles

Step-by-step explanation:

The square of an integer is called a perfect square. For example, 49 is a perfect square because 7² = 49. When a radicand is not a perfect square, you can estimate the square root of the radicand.

x²-8x=768

x²-8x-768=0

(x-32)(x+24)=0

x=32 x=-24

you use 32 because it can be negative

plug in for x

(32)(32-8)(1)=768

32×24=768

this isn't the completing the square method though this is zero product law

a. Equation that represents the volume of the rectangular prism glass is:  (x)(x - 8)(1) = 768

b. The dimensions are, length = 32 cm, width = 24 cm.

Volume = (l)(w)(h)

Given the following dimensions of the glass case:

a. Plug in the values into the volume formula to find the equation

(x)(x - 8)(1) = 768

x² - 8x - 768 = 0

b. Factorize x² - 8x - 768 = 0 to find the x, and find the dimensions of the rectangular prism glass

x² - 8x - 768 = 0

(x + 24)(x - 32) = 0

x= −24 or x = 32

The length cannot be a negative number, so:

Length of the glass = x = 32 cm

Width = x - 8 = 32 - 8 = 24 cm

[tex]\[ 25 \times 3 = 75 \][/tex]

Explanation:

To express the multiplication of 25 and 3 as a numerical expression, we use the multiplication symbol "×" to indicate the operation. Therefore, the numerical expression for the product of 25 and 3 is [tex]\( 25 \times 3 \).[/tex]

To calculate this, we simply multiply 25 by 3:

[tex]\[ 25 \times 3 = 75 \][/tex]

Answer:

C

Step-by-step explanation:

To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).

[tex]y -y_1 = m(x-x_1)\\y --3=-\frac{1}{2}(x--2)\\y+3 = -\frac{1}{2}(x+2)[/tex]

Convert to standard form by applying the distributive property and rearranging the terms.

[tex]y + 3 = -\frac{1}{2}(x+2)\\y+3 = -\frac{1}{2}x -1\\2y + 6 = -x -2\\x+2y + 6 = -2\\x + 2y = -8[/tex]

Answer: Hello there!

we want to find the equation that passes through the point (6, -8) (where this notation stands for (x,y)) with a slope of 0.

a linear equation has the form y = ax+ b

where a is the slope and b is the intercept.

if a = 0, our equation has the form y = b (has no dependence of x)

so we have a constant equation that passes through the point (6, -8) , this means x = 6 and y = -8, but we know that y is constant:

then y = -8 = b

so our equation is y(x) = -8

Division! Since litres is a larger unit then millimeters, the value will need to decrease to make up for the change in units. So division is needed.

To convert milliliters to liters, use division because you're converting from a smaller to a larger unit, with 1000 milliliters equaling one liter.

To convert milliliters to liters, you would use division. This is because the process involves going from a smaller unit of measurement to a larger one, and there are 1000 milliliters in one liter. Therefore, you move the decimal point three places to the left. For example, converting 60,000 milliliters to liters, you would calculate 60,000 milliliters / 1000, resulting in 60 liters.

In solving multi-step division problems with compound units or applying compound unit multiplication in word problems, it is essential to convert all values into the same units using multiplication and division. When dealing with compound unit conversions such as milliliters to liters, division helps find the total amount or cost for a given volume in liters after initially representing values in milliliters.

3+|n•-9|=4

|n•-9|=1

n•-9=1 Or n•-9= -1

n= -1/9 n=1/9

n=±1/9

Answer:

The value of x is ± (1/9).

Step-by-step explanation:

Consider the provided statement.

If 3 is added to the absolute value of the product of a number and −9,

Now convert this into mathematical form.

Let the number is x then the product of number and -9 is -9x.

For absolute value we use the mode. Thus the required expression is:

3 + |-9x|

Now it is given that the result is equal to 4. Thus,

3 + |-9x| = 4

Solve the above equation as shown:

|-9x| = 4-3

|-9x| = 1

Now remove the mode by introducing ± sign as shown:

-9x = ± 1

-9x = 1 or -9x = -1

x = -1/9 or x = 1/9

Hence, the value of x is ± (1/9).

We have been given a triangle ABC. Points L, M and N re midpoints of the triangle. We are asked to find the median of segment BC.

We know that median of a triangle is line segment connecting the midpoint of a segment to the opposite vertex.

We can see that angle A is the opposite angle to side BC and M is the midpoint of side BC, therefore, segment AM is the median to side BC and 1st option is the correct choice.

U find the rate of change by using the equation:

Y^2-y^1

————-

X^2-x^1

You can use the formula to find the rate of change:

Rate of change = (y₂ - y₁) / (x₂ - x₁)

To find the rate of change using a graph, you need to determine the slope of the graphed line or curve at a specific point. The slope represents the rate at which the dependent variable changes with respect to the independent variable.

Here's a step-by-step process to find the rate of change using a graph:

a) Identify two points on the graph that you want to calculate the rate of change between.

These points should have known coordinates (x₁, y₁) and (x₂, y₂).

b) Calculate the difference in the dependent variable (y) between the two points: Δy = y₂ - y₁.

c) Calculate the difference in the independent variable (x) between the two points: Δx = x₂ - x₁.

d) Divide the difference in the dependent variable by the difference in the independent variable: Δy/Δx.

e) The result of this calculation represents the average rate of change between the two points. If you want to find the instantaneous rate of change at a specific point, you can make the interval between the two points infinitesimally small by moving the points closer together. In this case, the rate of change will be represented by the slope of the tangent line to the graph at that point.

By following these steps, you can determine the rate of change at a particular point on a graph.

Answer:

option D

0 < t < 3

Step-by-step explanation:

Given in the question the equation

d = 144 - 16t²

where d is the distance

           t is the time

Since, it is a descent, d should be decreasing until it reaches zero

by plugging d = 0 in the equation

0 = 144 - 16t²

-144 = -16t²

144/16 = t²

t² = 9

take square root on both sides

√t² = √9

t = ±3

since time can't be negative so we will reject -3

t = 3

This means that at 3 seconds the roller coaster was at ground but before that it was in the air

so when t < 3 Greg's car was moving in the air.

A function is a relationship between inputs where each input is related to exactly one output.

The graph in option D shows one-to-many which is not a function.

The graph in option D represents a non-functional relationship.

Option D is the correct answer

A function is a relationship between inputs where each input is related to exactly one output.

Example: f(x) = 2x is a function.

x = input

2x = output

We have,

A function can have two inputs and have the same output.

This property is called many-to-one function

For example f(x) = (-x)²,

x = 1, -1

f(1) = 1

f(-1) = 1

But a function can not have different outputs for the same inputs.

This property is called one-to-many function.

The given graph in the options are:

A - this graph represents a functional relationship.

B - this graph represents a functional relationship as many-to-one function.

C - this graph represents a functional relationship.

D - this graph represents a non-functional relationship because it is a one-to-many function

Thus,

The graph in option D shows one-to-many which is not a function.
