The difference between the roots of the equation 2x^2−5x+c=0 is 0.25. Find c.

Answer:

Step-by-step explanation:

All you have to do here is to divide polynomial f(x) = (x + 16)/x by polynomial g(x) = 2x / (x + 4), simplify the result and label the quotient properly.  Recall that division by a fraction involves inverting the divisor fraction and then multiplying.

               (x + 16)       (x + 4)      (x + 16)(x + 4)

(f/g)(x) = ------------- * ----------- = --------------------

                    x              2x                 2x^2

Note that this quotient is true for all x except x = 0.

Answer:

2u^2 +6aux+4ax

Step-by-step explanation:

2u^2 because u×2u

2aux cuz u× 2ax

4aux cuz 2ax×2u

4ax. cuz 2ax time 2ax

The multiplication of the binomials (u+2ax)(2u+2ax) can be solved using the FOIL method. The steps result in 2u^2 + 2uax + 4uax + 4a^2x^2. Combining like terms yields the final answer: 2u^2 + 6uax + 4a^2x^2.

The problem (u+2ax)(2u+2ax) is a mathematical multiplication of two binomial expressions. You may solve it by applying the distributive property, also known as the FOIL method (First, Outer, Inner, Last). Let's walk through the steps to solve it:

Then, add these results together: 2u^2 + 2uax + 4uax + 4a^2x^2. Combine like terms to get the final answer: 2u^2 + 6uax + 4a^2x^2.

Answer:

3/10 fraction of a pizza is received by each person.

Step-by-step explanation:

3 pizzas are shared among 10 people. We need to find the fraction of pizza each person receive.

No of pizzas = 3

Answer:

a*b = 8

Step-by-step explanation:

a-b =2

Let b= 2

a-2 =2

Add 2 to each side

a-2+2 =2+2

a =4

We want to find a*b

4*2 = 8

a*b = 8

First substitute 2 in for b to get a - (2) = 2.

Now isolate a by adding 2 to both sides to get a = 4.

Since a = 4, substitute 4 in for a and 2 in for b to get 4 × 2.

Multiplying, 4 × 2 gives us a product of 8.

So the value of a × b is 8.

The number of right questions is 18

Let the number of right questions be x, and the wrong questions be y

So, we have the following equations

x + y = 25

4x - y = 65

Answer:

Adults are given =

2n oranges

2n+n=once given

so

Step-by-step explanation:

The algebraic expression for the number of oranges given to adults in a group with an equal number of adults and children, with a specified distribution of oranges and a remainder, is 2A, where A represents the number of adults (or children, since they are equal).

The question requires us to find an algebraic expression for the number of oranges given to the adults in a group where there are an equal number of adults and children, and a specific distribution of oranges to adults and children with a remainder.

Let's denote the number of adults by A, and thus, the number of children will also be A since the group has an equal number of adults and children. If n oranges are distributed, and each adult receives 2 oranges, then the total number of oranges given to adults is 2A. Each child receives one orange, so the number of oranges given to children is A. Including the 5 oranges that are left, the equation representing the total number of oranges is: 2A (for adults) + A (for children) + 5 (leftover) = n (total oranges).

From this equation, if you want to isolate the expression that represents the number of oranges given to adults, it is simply 2A.

Answer:

I think it's B (Sorry if im wrong)

Answer:

2. 0.4

Step-by-step explanation:

Solve for "x" by simplifying both sides of the equation, then isolating the variable.

The solution of the equation is x = 0.4.

Given: Equation

[tex]\frac{3}{5}(x+\frac{4}{3})=1.04[/tex]

Now, we have to solve for x.

[tex]\frac{3}{5}(x+\frac{4}{3})=1.04[/tex]

Multiplying both sides by 5, we get:

⇒ 3(x + 4/3) = 1.04 × 5

⇒ 3x + 4 = 5.2

⇒ 3x = 5.2 - 4

⇒ 3x = 1.2

Dividing both sides by 3, we get:

⇒ x = 0.4

Therefore, the solution of the given equation is x = 0.4.

Hence, option (2) is correct.

Step-by-step explanation:

because 2:3 is some as 3x:x in terms of speed

Answer: The speed of her walking is 4 mph and the speed of her jogging is 6 mph.

Step-by-step explanation:

Since we have given that

Time taken by Lorena to walk the path = 30 minutes

Time taken by Loren to jogs the path = 20 minutes

Let the speed of her walking be 'x'.

Let the speed of her jogging be 'x+2'.

Since distance would remain same, so it becomes,

[tex]30x=20(x+2)\\\\30x=20x+40\\\\30x-20x=40\\\\10x=40\\\\x=\dfrac{40}{10}\\\\x=4\ mph[/tex]

Hence, the speed of her walking is 4 mph and the speed of her jogging is 6 mph.

Answer:

7.6m/s

Step-by-step explanation:

Find the time the Olympian swam

Speed=distance/time ⇒⇒Time=distance/speed

Distance=200m , speed= 1.8m/s   t= 200/1.8 = 111.11 seconds

Find the speed of the Olympic runner

Distance=200m  time = 21.3 sec  

s=200/21.3 = 9.4 m/s

Difference in speed= 9.4-1.8= 7.6m/s

Answer:

7.6 m/s faster

Step-by-step explanation:

Speed of swimmer = 1.8 meters per second

The distance covered by runner = 200

Time of runner = 21.3 sec

We have to find the speed of the runner first so that we can compare with the speed of swimmer.

Speed = Distance/Time

=> 200/21.3

=> 9.4 m/s

So we have to find the difference between both speeds

Difference = 9.4 - 1.8

=> 7.6 m/s

So the runner was 7.6 m/s faster..

Answer:

$5,000

Step-by-step explanation:

Create a proportion:

100(550)/11

5,000= x

You have to form a proportion: [tex]\frac{part}{whole}[/tex]

Meals are only 11% for the vacation budget. This means that meals would go over 100% like this:

[tex]\frac{11}{100}[/tex]

You also know that you have $550 for meal (your part) but you want to know what your total vacation budget is(your whole)[tex]\frac{x}{550}[/tex] (x), so you would set it up like this

Now you sent them equal to solve for x:

[tex]\frac{11}{100} = [tex]\frac{550}{x}[/tex]

cross multiply:

11x = 55,000

x = 5,000

This means that your total vacation budget is $5,000

Step-by-step explanation:

The center of the circle is (0, -2). The dark-filled circle is the center and lies 2 units below the origin on the y-axis.

On the other hand, the radius of the circle is 3 units. If we count from the dark-filled circle, we have 3 complete squares to the left, to the right.

Now the standard equation of a circle with center (a, b) and radius r units is given by the formula;

Answer:

total resistance is 54.54 ohms

Step-by-step explanation:

In parallel circuits, current can take various paths so the resistance are not added simply like that in series circuit, instead the reciprocal of total resistance in parallel circuit is calculated by adding the reciprocals of all the resistors connected parallel in circuit.

Given:

Resistor r1= 100

resistor r2 = 200

resistor r3= 300

The three resistors are connected in parallel  so the total resistance will be calculated by:

1/R= 1/r1 +1/r2 +1/r3

Putting the values of r1, r2, r3 in above we get

1/R= 1/100 + 1/200 +1/300

  = 0.01 + 0.005 + 0.0033

  = 0.0183

Taking reciprocal of both sides:

R=54.54

Hence total resistance is 54.54 ohms!

Final answer:

The total resistance of three resistors rated at 100 Ω, 200 Ω, and 300 Ω connected in parallel is approximately 54.64 Ω. This is calculated using the reciprocal formula for parallel resistances.

Explanation:

When you have a circuit with resistors connected in parallel, the total (or equivalent) resistance of the circuit is found by using the reciprocal formula:

Rtotal = 1/(1/R1 + 1/R2 + 1/R3)

For the given resistors of 100 Ω, 200 Ω, and 300 Ω in parallel, you calculate the total resistance like this:

Rtotal = 1/(1/100 Ω + 1/200 Ω + 1/300 Ω)
= 1/(0.01 Ω-1 + 0.005 Ω-1 + 0.0033 Ω-1)
= 1/(0.0183 Ω-1)
= 54.64 Ω

The total resistance of the circuit would therefore be approximately 54.64 Ω.

We have

So, in your case, we have

Answer:

Option D. 1/64

Step-by-step explanation:

We have to simplify the following expression

[tex]4^{-\frac{11}{3} }[/tex] ÷ [tex]4^{-\frac{2}{3} }[/tex]

= [tex]\frac{4^{-\frac{11}{3} } }{4^{-\frac{2}{3} } }[/tex]

= [tex][4^{-\frac{11}{3}}[/tex] × [tex]4^{\frac{2}{3}}][/tex] [since [tex]\frac{1}{A-1}[/tex]=a]

= [tex]4^{(-\frac{11}{3}+\frac{2}{3})}[/tex] [since [tex]a^{b}[/tex] × [tex]a^{c}[/tex] = [tex]a^{(b+c)}[/tex]]

= [tex]4^{-\frac{9}{3}}[/tex]

= [tex]4^{-3}[/tex]

= [tex]\frac{1}{4^{3} }[/tex]  [[tex]a^{-1}=\frac{1}{a}[/tex]]

= [tex]\frac{1}{64}[/tex]

Option D. 1/64 is the answer.
