When asked to factor the trinomial 4x^2+20x+25, a student gives the answer (2x-5)(2x-5). What is one thing wrong with this answer?

Lou spends the total amount would be $26.98 on​ gas which is determined by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

The following information is provided in the problem :

Lou topped up the tank with $3.80 per gallon of petrol.

Lou's car's 13-gallon tank held 5.9 gallons.

If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.

So the total amount would be:

⇒ (13 - 5.9)(3.80)

⇒ (7.1)(3.80)

⇒ 26.98.

Therefore, the total amount would be $26.98

Answer: Option a) 33 1/3 lbs

Solution:

Be

Attraction force (F) varies inversely as the square of the distance between them:

F=k/d^2

Constant of proportionality: k

Distance between the two masses: d

F=75 lbs when d=8 feet

Replacing in the formula above:

F=k/d^2

75 lbs=k/(8 feet)^2

Squaring in the denominator:

75 lbs=k/(64 feet^2)

Solving for k: Multiplying both sides of the equation by 64 feet^2:

(64 feet^2)(75 lbs)=(64 feet^2)[k/(64 feet^2)]

4,800 lbs*feet^2=k

k=4,800 lbs*feet^2

F=k/d^2

F=4,800 lbs*feet^2/d^2

Find the attraction when the masses are twelve feet apart:

F=?

d=12 feet

Replacing in the formula:

F=4,800 lbs*feet^2/(12 feet)^2

Squaring in the denominator:

F=4,800 lbs*feet^2 / (144 feet^2)

Dividing:

F=(4,800/48)/(144/48) lbs

F=100/3 lbs

F=(99+1)/3 lbs

F=(99/3+1/3) lbs

F=33 1/3 lbs

Final answer:

Using Newton's inverse square law for gravitational force, it is determined that the force of attraction will be a) 33 1/3 lbs when the distance between the masses is increased from 8 to 12 feet.

Explanation:

The scenario described falls under the gravitational force law stated by Isaac Newton, which is a fundamental concept in Physics. The force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them (F ∝ 1/d²). We are given that the gravitational attraction is 75 lbs when the bodies are 8 feet apart. To find the force at a distance of 12 feet, we use the inverse square law which indicates that increasing distance reduces gravitational force.

Let F1 be the initial force and d1 be the initial distance, and let F2 be the force at a new distance d2. According to the inverse square law, we have F1/F2 = (d2/d1)². Plugging in the values F1 = 75 lbs, d1 = 8 feet, and d2 = 12 feet, we get 75/F2 = (12/8)² = 2.25. Solving for F2, we find that F2 = 75 / 2.25 = 33.33 lbs.

Therefore, the gravitational attraction when the masses are twelve feet apart is 33 1/3 lbs.

Solution: The another way to show the Fuaad's solution is [tex]x>7[/tex].

Explanation:

It is given that the solution of an inequality is [tex]-12<x>7[/tex].

It can be break in two parts [tex]-12<x[/tex] and [tex]x>7[/tex].

The inequality [tex]-12<x[/tex] means the values of x is greater than [tex]-12[/tex] and the inequality [tex]x>7[/tex] means the value of x is greater that than 7.

When we combine both results we get [tex]x>7[/tex] it means the value of x is greater than 7.

It can also represented by number line as shown in given figure.

The number line shows the values of x and red lines shows the solution of both inequalities [tex]-12<x[/tex] and [tex]x>7[/tex].

The common region shows the combination of both the possible inequalities, therefore the  another way to show the Fuaad's solution is [tex]x>7[/tex].

Answer:

C (btw its x less than 7)

Step-by-step explanation:

Becuase the first option represents that the arrows go separate ways to infin.

the second option states that one variable is greater than of equal to and the other is only <

the third correctly shows and represents the inequality

the fourth one has the OR which means a number that is plugged in only needs to satisfy one of the inequalities which is not the point.

Answer:

If you know that the function is not odd, you know that the graph does not have rotational symmetry

Step-by-step explanation:

There is a theorem that says: "A function is odd if, and only if, its graph is symmetric with respect to the origin, or it has rotational symmetry in 180 ° with respect to the origin"

This statement is equivalent to:

If a function is odd, its graph has rotational symmetry with respect to the origin

If a graph has rotational symmetry with respect to the origin then the function is odd.

Therefore, it is impossible for the graph to have rotational symmetry with respect to the origin and the function is not odd.

Then, if you know that the function is not odd, you know that the graph does not have rotational symmetry

Is it 20?? I'm severely confused by this question too lol.

Hi!

[tex]x=\frac{\sqrt[]{145-7} }{8}, or x=-\frac{7+\sqrt{145} }{8}[/tex]

Explanation: First you had to multiply by 4x+9 from both sides. Then simplify, it gave us 2x(4x+9)-(4x+9)=3. Next you can also solve 2x(4x+9)-(4x+9)=3.

Cost of producing and selling x tables is given by the function C(x)=50x+3000

x is the number of tables produced

Each table is sold for $70

So selling price of x tables S(x) = 70x

Now we find the number of table must be sold for the firm to break even

Break even occurs when selling price = cost price

That is S(x) = C(x)

70x = 50x + 3000

Subtract 50x on both sides

20x = 3000

x = 150

150 tables  must be sold for the firm to break even

Hey there,

So the answer is 13.

The explanation is:

We are asked to find f(10), so let's evaluate this function at 10 by plugging this in for x.

So, as we know about the 10, the f(x) is going to be this- f(10).

We put f(10)= 10 over 2 + 8= 5+8 = 13

We have to flip the 8.

So you answer should be 13

It depends on how t is approaching 2.

In fact, if you consider the right limit, you have

[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{|t-2|} [/tex]

But since t is greater than 2, t-2 is positive, and thus |t-2| = t-2.

So, the limit becomes

[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{t-2} = \lim_{t \to 2^+} -1 = -1 [/tex]

On the other hand, if you consider the left limit, you have

[tex] \displaystyle \lim_{t \to 2^-} \dfrac{2-t}{|t-2|} [/tex]

But since t is less than 2, t-2 is negative, and thus |t-2| = -t+2.

So, the limit becomes

[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{-t+2} = \lim_{t \to 2^+} 1 = 1 [/tex]
