What is the remainder when the polynomial 8x^2+4x−3 is divided by 2x−1?

Answers

Answer 1
The remainder of this polynomial is 1. 
Answer 2

Answer:

1

Step-by-step explanation:

Given: A polynomial [tex]8x^{2} +4x-3[/tex] is divided by another polynomial [tex]2x-1[/tex]

To find: Remainder when [tex]8x^{2} +4x-3[/tex]  is divided by [tex]2x-1[/tex]

Solution:

To find the remainder when [tex]8x^{2} +4x-3[/tex]  is divided by [tex]2x-1[/tex]

First, equate [tex]2x-1[/tex] with 0.

Now, [tex]2x-1=0[/tex]

[tex]\implies2x=1[/tex]

[tex]\implies x=\frac{1}{2}[/tex]

Now, to find the remainder put [tex]x=\frac{1}{2}[/tex] in [tex]8x^{2} +4x-3[/tex]

So, we have

[tex]8\times(\frac{1}{2})^{2}+4(\frac{1}{2} )-3[/tex]

[tex]=8\times\frac{1}{4} +2-3[/tex]

[tex]=2+2-3[/tex]

[tex]=4-3[/tex]

[tex]=1[/tex]

Hence, the remainder is 1.

Answer:

The answer is b. I and III

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To Answer this question we need to first understand what each type of income is.

Earned Income refers to the an amount of money received from the act of providing goods or services. Such Income includes Salaries, Paychecks, Sub-contracting work etc.

Passive Income is a periodic inflow of cash received with little to no effort on the part of the beneficiary.

Capital Gains Income refers to the money made on selling a certain asset above the value of purchase.

Know that we have this information we can see that Padraig has two types of incomes. Both Earned Income from his salary and Capital Gains Income from the stocks that he sold. Therefore the answer is b. I and III

If p is true and q is false, the p -> q is always, sometimes, never true.

When p is false and q is true, then p or q is always, sometimes, never true.

If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.

If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.

If p -> q is true and q is true, then p always, sometimes, never is

Answers

1. If p is true and q is false, the p -> q is never true.

2. When p is false and q is true, then p or q is always true.

3. If p is true and ~ q is false, then p -> ~ q is never false.

4. If p is true and q is true, then ~ p -> ~ q is always true.

5. If p -> q is true and q is true, then p is always true.

Further Explanation:

The logic gates are used here.

Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.

So let us look at all the questions one by one.

1. If p is true and q is false, the p -> q is always, sometimes, never true.

p -> q

true -> false

The true should imply true so the given statement will never be true.

2. When p is false and q is true, then p or q is always, sometimes, never true.

false or true

We know that in or gate even if one input is true, the whole output is true. So this statement will be always true given p is false and q is true.

3. If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.

This translates to:

true -> true

So it will never be false.

4. If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.

This translates to:

false -> false

This will always be true.

5. If p -> q is true and q is true, then p is always, sometimes, never true.

If p->q is true and q is true then p will always be true. "Implies to" states that in p->q, in order for q to be true p has to be true. So p will always be true.

jessie uses 20 liters of gasoline to travel 200kilometers, how many liters of gasoline will he use on a trip of 700 kilometer?

Answers

Answer: He will use 70 liters of gasoline on a trip of 700 kilometer.

Step-by-step explanation:

Given : Jessie uses 20 liters of gasoline to travel 200 kilometers.

We assume that the rate of consumption of gasoline is contant.

By UNITARY METHOD, the amount of gasoline required for 1 kilometer distance = [tex]\dfrac{20}{200}=\dfrac{1}{10}[/tex] liter

Now, the amount of gasoline required for 700 kilometer distance = [tex]700\times\dfrac{1}{10}=70[/tex] liters

Hence, He will use 70 liters of gasoline on a trip of 700 kilometer.

To calculate how many liters of gasoline Jessie will use for a 700 km trip, the fuel efficiency is first determined to be 10 km/L from the given data. Using this information, it is found that Jessie will need 70 liters of gasoline for the 700 km trip.

Jessie uses 20 liters of gasoline to travel 200 kilometers. To determine how much gasoline Jessie will use on a trip of 700 kilometers, we first need to find the fuel efficiency of the vehicle. By dividing the distance traveled by the amount of gasoline used, we get the fuel consumption rate:

Fuel efficiency = Distance / Gasoline

Fuel efficiency = 200 km / 20 L

Fuel efficiency = 10 km/L

Now we know that the vehicle uses one liter of gasoline to travel 10 kilometers. To find out how many liters are needed for a 700 km trip, we apply the following:

Gasoline needed = Trip distance / Fuel efficiency

Gasoline needed = 700 km / (10 km/L)

Gasoline needed = 70 liters

Therefore, Jessie will use 70 liters of gasoline to travel 700 kilometers.

Find the point on the line y = 92x closest to the point (1, 0)

Answers

Let the point on the line y = 92x closest to the point (1, 0) be (x, 92x), then the distance between point (1, 0) and (x, 92x) is given by:

[tex]L=\sqrt{(x-1)^2+(92x-0)^2} \\ \\ =\sqrt{x^2-2x+1+8464x^2}=\sqrt{8465x^2-2x+1}[/tex]

For shortest distance,

[tex] \frac{dL}{dx} =0[/tex]

[tex] \frac{dL}{dx} =0 \\ \\ \Rightarrow \frac{16930x-2}{2\sqrt{8465x^2-2x+1}} =0 \\ \\ \Rightarrow16930x=2 \\ \\ \Rightarrow x= \frac{1}{8465} [/tex]

and [tex]y=92\left(\frac{1}{8465}\right)=\frac{92}{8465}[/tex]

Therefore, the required point is [tex]\left(\frac{1}{8465},\ \frac{92}{8465}\right)[/tex]

A triangle has sides of length 5 cm and 11 cm. What can you say about the length of the third​ side?

Answers

Final answer:

The length of the third side of the triangle must be greater than 6 cm and less than 16 cm, as per the triangle inequality theorem.

Explanation:

According to the triangle inequality theorem, the length of any side of a triangle must be less than the sum of the other two sides and greater than the difference between them. Therefore, the third side of a triangle with sides of length 5 cm and 11 cm must be longer than 6 cm (11 cm - 5 cm) and shorter than 16 cm (11 cm + 5 cm). To clarify, for any triangle with sides a, b, and c, where c is the longest side, the following must always be true: a + b > c and |a - b| < c.

With this question you will distribute and add. You want to do this from left to right.

2*x = 2x
2*-4 = -8

Now the equation is (2x-8)+7(x+2). This is where you distribute again.
7*x = 7x
7*2 = 14

The equation is now (2x-8)+(7x+14) which can also be rewritten to be 2x - 8 + 7x + 14. Here you combine like terms through adding.
2x + 7x = 9x
14 - 8 = 6

Remember to always keep the sign of the number when adding. This means your answer would be 9x+6 or 6+9x.
