What is the equation of the parabola?

Answer:

There is a multiplication error

Step-by-step explanation:

Long division method is used to divide greater  number by a smaller number.

Here, greater number is known as the dividend and smaller number is known as divisor.

As per division algorithm,

Dividend = Divisor [tex]\times[/tex] quotient + remainder

Here, dividend = [tex]8x^3-36x^2+54x-27[/tex]

Divisor = [tex]2x-3[/tex]

Here, we need to find the error in the long division .

In step:

[tex]18x+27[/tex] , it should be 18x-27 as [tex]-3\times 9=-27[/tex] not +27

So, there is a multiplication error .

The correct option is c) she makes a multiplication error.

Step-by-step explanation:

Given :

Dividend = [tex]8x^3-36x^2+54x-27[/tex]

Divisor = [tex]2x-3[/tex]

Solution :

In step [tex]18x +27[/tex] there is mistake. It should be [tex]18x - 27[/tex] because [tex]-3 \times 9= -27[/tex] not +27.

Therefore the correct option is c) she makes a multiplication error.

Answer:

Table for y = 2|x-4| + 3 on domain {2,3,4,5,6} is given as:

x                           y

2         2|x-4| + 3 = 2|2-4| + 3 = 7

3         2|x-4| + 3 = 2|3-4| + 3 = 5

4         2|x-4| + 3 = 2|4-4| + 3 = 3

5         2|x-4| + 3 = 2|5-4| + 3 = 5

6         2|x-4| + 3 = 2|6-4| + 3 = 7

The graph of the absolute value function y = 2|x-4| + 3 for the given domain is attached.

Step-by-step explanation:

The absolute value parent function, written as function(x) = | x |, is defined as:

|x| = x          and           |-x| = x

In our case;

For x = 2        

y = 2|x-4| + 3

= 2|2-4| + 3

= 2|-2| + 3

= 2*2 + 3

= 4 + 3

= 7

Similarly, for all other values of x in the given domain, value of y can be calculated.

Answer:

Step-by-step explanation:

[tex]|a|=\left\{\begin{array}{ccc}a&for\ a\geq0\\-a&for\ a<0\end{array}\right[/tex]

Put each value of x from the set {2, 3, 4, 5, 6}

to the equation y = 2|x - 4| + 3:

x = 2 → y = 2|2 - 4| + 3 = 2|-2| + 3 = 2(2) + 3 = 4 + 3 = 7 → (2, 7)

x = 3 → y = 2|3 - 4| + 3 = 2|-1| + 3 = 2(1) + 3 = 2 + 3 = 5 → (3, 5)

x = 4 → y = 2|4 - 4| + 3 = 2|0| + 3 = 2(0) + 3 = 0 + 3 = 3 → (4, 3)

x = 5 → y = 2|5 - 4| + 3 = 2|1| + 3 = 2(1) + 3 = 2 + 3 = 5 → (5, 5)

x = 6 → y = 2|6 - 4| + 3 = 2|2| + 3 = 2(2) + 3 = 4 + 3 = 7 → (6, 7)

Mark the points in the coordinates system.

The domain is only five numbers, therefore the graph of this function is only five points.

In this case we have the following expressions provided in the exercise:

[tex]\sqrt{3x}[/tex] and [tex]x\sqrt{3}[/tex]

Based on the property mentioned before the expression [tex]\sqrt{3x}[/tex] cannot be simplified. So 3 and  [tex]x[/tex] stays inside the square root.

Therefore, the conclusion is: The expression [tex]\sqrt{3x}[/tex] is not equivalent to the expression [tex]x\sqrt{3}[/tex]

Deciphering the expressions reveals that 'square root 3x' is not equivalent to 'x square root 3'. They interpret differently on the terms inside and outside of the square root, thus they are not the same.

The statement 'the expression square root 3x is equivalent to the expression x square root 3' is False. To understand why, we need to understand the properties of square roots and multiplication. The expression square root 3x means that the square root is being taken over the entire product of 3x. This is not the same as x square root 3, where the square root is only being applied to 3, and then that result is being multiplied by x.

Step-by-step explanation:

The length of the diagonal is:

d² = w² + l² + h²

Given d = 36, l = 30, and h = 6:

36² = w² + 30² + 6²

1296 = w² + 900 + 36

w² = 360

w = 6√10

w ≈ 19.0

Step-by-step explanation:

The options are shown in the pictures attached.

Data:

a single dog costs about $6 per day

y-variable represents the total cost

x-variable represents days

So, 1 day costs $6, 2 days costs 2*$6 = $12, 3 days costs 3*$6 = $18 and so on. Then, the table is:

x     y

6     6*6 = 36

9     9*6 = 54

12    12*6 = 72

[tex]\( f(x) + g(x) \) equals \( 2x^2 - 5x - 8 \).[/tex] (option b)

To find [tex]\( f(x) + g(x) \)[/tex], we need to add the functions f(x) and g(x):

[tex]\[ f(x) + g(x) = (2x^2 + 3x - 4) + (-8x - 4) \][/tex]

[tex]\[ = 2x^2 + 3x - 4 - 8x - 4 \][/tex]

[tex]\[ = 2x^2 + (3x - 8x) + (-4 - 4) \][/tex]

[tex]\[ = 2x^2 - 5x - 8 \][/tex]

Therefore, the correct answer is:

[tex]\[ f(x) = 2x^2 - 5x - 8 \][/tex]

Complete question: If f(x)=2x²+3x−4, and g(x)=−8x−4, what does f(x)+g(x) equal?

B. [tex]^\leftrightarrow_{AB}[/tex] and [tex]^\leftrightarrow_{CD}[/tex]  are perpendicular lines.

Step-by-step explanation:

We can quickly plot the points in the cartesian plane as shown in the attachment.

A visual representation will help us see that A,B,C, and D do not lie on the same line.

The slope of AB  is [tex]\frac{4-1}{-2--8} =\frac{3}{6}=\frac{1}{2}[/tex]

The slope of CD is [tex]\frac{5--1}{-6--3} =\frac{6}{-3}=-2[/tex]

The two slopes are negative reciprocals of each other.

It is true that line AB and line CD are perpendicular.

These two lines cannot be perpendicular and parallel at the same time.

It is also not possible that, the two lines are perpendicular but will not intersect

Answer:

b) L+S=80 and 2.75L+3.25S=245

Step-by-step explanation:

L stands for larger softballs. S stands for smaller softballs.

If you are ordering 80 softballs, then L and S represent the number of softballs of each one (large or small) to get a total of 80.

2.75 is the price of a large softball

3.25 is the price of a small softball.

You multiply the amount of each softball to how many of those kinds of softballs you get, you will then get the sum of the amount you ordered for 80 softballs: 245 dollars.

So thus the answer is B

Answer:

L+S=80

2.75L+3.25S=245

Choice B

Step-by-step explanation:

Larger ball costs $2.75.

Smaller ball costs $3.25.

You order a total of 80 softballs for $245.

So L is for number of large balls.

S is for number of small balls.

So we have 80 balls in all, some are small and some are large. This means the number of large plus the number of small equals 80.

So we have this equation L+S=80.

Now if you buy L balls, you spend 2.75 times L on large balls altogether.

If you buy S balls, you spend 3.25 times S on small balls altogether.

So together you spend 2.75L+3.25S.  They gave us that this amount should be equal to 245.

So this equations is 2.75L+3.25S=245

We are looking for the choice that contains these equations:

L+S=80

2.75L+3.25S=245

Answer:

9 geese

11 cows

Step-by-step explanation:

Say x is cows, and y is geese.

x + y = 20 animals

x * 4 + y * 2 = 62

x = 20 - y

(20 - y) * 4 + y * 2 = 62

80 - 4y + 2y = 62

- 2y = -18

y = 9 geese

x = 20 - 9 = 11 cows

Lisa has 11 cows and 9 geese.

To solve the problem involving Lisa's barn with 20 animals having 62 legs in total, and knowing she only has cows and geese, we can use a system of linear equations. We can denote the number of cows as c and the number of geese as g. Cows have 4 legs and geese have 2 legs.

We can then set up the following equations based on the information given:

Cows and geese equation: c + g = 20 (since there are 20 animals in total)

Legs equation: 4c + 2g = 62 (because cows have 4 legs and geese have 2 legs)

Now, let's solve the system of equations:

Multiply the first equation by 2 to match the number of geese legs in the second equation: 2c + 2g = 40

Subtract the modified first equation from the legs equation: (4c + 2g) - (2c + 2g) = 62 - 40, which simplifies to 2c = 22, and then c = 11. Lisa has 11 cows.

Substitute the number of cows back into the first equation to find the number of geese: 11 + g = 20, which leads to g = 9. Lisa has 9 geese.

Therefore, Lisa has 11 cows and 9 geese.

Step-by-step explanation:  We are given to select the correct equation that is equivalent to the following equation :

[tex]2^{4x}=8^{x-3}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Equivalent equations means  two equations that can be obtained from one another using some properties of formula.

We will be using the following formula :

[tex](a^b)^c=a^{b\times c}.[/tex]

From equation (i), we have

[tex]2^{4x}=8^{x-3}\\\\\Rightarrow 2^{4x}=(2^3)^{x-3}\\\\\Rightarrow 2^{4x}=2^{3\times(x-3)}\\\\\Rightarrow 2^{4x}=2^{3x-9}.[/tex]

Thus, the required equivalent equation is [tex]2^{4x}=2^{3x-9}.[/tex]

Option (D) is CORRECT.
