Answer:

is that a question

Step-by-step explanation:

1. The missing number is 17.

2. The missing number is 7.

3. The missing number is 5.

4. The missing numbers are 4 and 5.

1. For the expression x^2 + x + ?, we can find the missing numbers by comparing it to the factored form (x+1)(x+17). By expanding the factored form, we get x^2 + 18x + 17. Therefore, the missing number is 17.

2. For the expression x^2 + 9x + 14, we can find the missing numbers by comparing it to the factored form (x+2)(x+?). By expanding the factored form, we get x^2 + 2x + ?x + 2?. We need to find two numbers that multiply to 14 and add up to 9. The numbers that satisfy these conditions are 2 and 7. Therefore, the missing number is 7.

3. For the expression x^2 - 7x + 10, we can find the missing numbers by comparing it to the factored form (x-2)(x-?). By expanding the factored form, we get x^2 - 2x - ?x + 2?. We need to find two numbers that multiply to 10 and add up to -7. The numbers that satisfy these conditions are -2 and -5. Therefore, the missing number is 5.

4. For the expression x^2 - 9x + 20, we can find the missing numbers by comparing it to the factored form (x-?)(x-?). By expanding the factored form, we get x^2 - ?x - ?x + ?. We need to find two numbers that multiply to 20 and add up to -9. The numbers that satisfy these conditions are -4 and -5. Therefore, the missing numbers are 4 and 5.

Step-by-step explanation:

Dominique should have paid $30

ex: 7.5 x 4.00= 30

Answer:

The third answer: -7/8

Step-by-step explanation:

Having the numerator negative makes the entire fraction negative. If both the numerator and the denominator are negative it means that the fraction is positive. So -7/8 is equal to - 7/8.

Answer:

Roses = x = 100

Carnations = y = 110

Lilies = z = 120

Step-by-step explanation:

Roses = $4.50

Carnations = $3.00

lilies = $2.50

Total flowers ordered = 330

Total cost = $1,080

Let

Roses = x

Carnations = y

Lilies = z

x + y + z = 330

4.50x + 3y + 2.50z = 1080

There are 20

more lilies than roses

z = x + 20

Substitute z = x + 20 into the equations

x + y + (x + 20) = 330

4.50x + 3y + 2.50(x + 20) = 1080

x + y + x + 20 = 330

4.50x + 3y + 2.50x + 50 = 1080

2x + y = 330 - 20

7x + 3y = 1080 - 50

2x + y = 310 (1)

7x + 3y = 1030 (2)

Multiply (1) by 3

6x + 3y = 930 (3)

7x + 3y = 1030 (2)

Subtract (3) from (2)

7x - 6x = 1030 - 930

x = 100

Substitute x = 100 into (1)

2x + y = 310

2(100)+ y = 310

200 + y = 310

y = 310 - 200

= 110

y = 110

Substitute the value of x and y into

x + y + z = 330

100 + 110 + z = 330

210 + z = 330

z = 330 - 210

= 120

z = 120

Roses = x = 100

Carnations = y = 110

Lilies = z = 120

Step-by-step explanation:

Hey there!

Given;

Vat%= 13%

Price after 13% vat = Rs. 2034

Price without vat = x

Then,

Price with vat= price with out vat + vat% of price with vat.

[tex]2034 = x + \frac{13}{100} \timesx [/tex]

[tex]2034 = \frac{100x + 13x}{100} [/tex]

[tex]2034 \times 100 = 113x[/tex]

[tex]x = \frac{2034 \times 100}{113} [/tex]

x = Rs.1800.

Therefore, the price without vat is Rs.1800.

The decomposition of Ni3 produces nitrogen gas and iodine. How many grams of the reactant would be required to react completely to give 1.18 g of iodine?To begin with, write the balanced equation for the decomposition of Ni3:2Ni3(s) → 3I2(s) + N2(g)

From the balanced equation above, the stoichiometric ratio between Ni3 and I2 is 2:3 that is, for every 2 moles of Ni3 decomposed, 3 moles of I2 is produced.To find the mass of Ni3 that would produce 1.18 g of I2, we need to find the number of moles of I2 produced first.The molar mass of I2 = 253.8 g/molNumber of moles of I2 produced = Mass / Molar mass = 1.18 / 253.8 = 0.004645 molFrom the stoichiometry, 2 moles of Ni3 produce 3 moles of I2, which can be written as:2 mol Ni3 → 3 mol I2

The number of moles of Ni3 that would produce 0.004645 mol of I2 can be obtained using the ratio:2 mol Ni3 / 3 mol I2 = 0.6666667 mol Ni3The mass of Ni3 required to produce 1.18 g of I2 can be obtained by multiplying the number of moles of Ni3 obtained above by the molar mass of Ni3:Mass = moles x molar mass = 0.6666667 x 100.7= 67.11 gTherefore, 67.11 g of Ni3 would be required to react completely to give 1.18 g of iodine.

Answer:

each number is the answer

Step-by-step explanation:

When calculating the impedance of a series R-L circuit, the total impedance is equal to the complex sum of the total series resistance and total series reactance. Therefore, the correct option is (c) impedance is equal to the complex sum of the total series resistance and total series reactance.

A series R-L circuit contains resistance and inductance components connected in series across an AC source. The voltage across both the resistance and the inductor is the same in a series R-L circuit. It is the total current through the circuit that is in phase with the resistor's voltage and 90° out of phase with the inductor's voltage. The inductive reactance is denoted by XL, which is a function of the inductor's value and the frequency of the AC supply.In an R-L circuit, there are two types of impedances: total impedance and phase angle. The total impedance Z is equal to the complex sum of the circuit's resistance and reactance. It is measured in ohms (Ω).Resistance is equal to the sum of resistances in series, and series reactance is equal to the sum of reactances in series.

The value of Matina's account in four years, considering the $2,000 deposits at the beginning of each year and a 5% annual interest rate, would be approximately $8,620.25.

To calculate the value of Matina's account in four years, we can use the formula for the future value of an ordinary annuity.

The formula is:

[tex]FV = P \times [(1 + r)^n - 1] / r[/tex]

Where:

FV is the future value of the annuity

P is the periodic payment or deposit amount

r is the interest rate per period

n is the number of periods.

P = $2,000 (deposit amount)

r = 5% = 0.05 (annual interest rate)

n = 4 (number of years)

Plugging in the values into the formula:

[tex]FV = $2,000 \times[(1 + 0.05)^4 - 1] / 0.05.[/tex]

Simplifying the expression:

[tex]FV = $2,000 \times [1.05^4 - 1] / 0.05[/tex]

Calculating the exponential term:

[tex]1.05^4\approx 1.21550625[/tex]

Plugging in the calculated value:

[tex]FV = $2,000 \times (1.21550625 - 1) / 0.05[/tex]

[tex]FV ≈ $2,000 \times 0.21550625 / 0.05[/tex]

FV ≈ $8,620.25

The length of the altitude is 9 units.

To solve this problem, we can use the geometric relationship in a right triangle between the lengths of the altitude, the hypotenuse, and the segments it divides.

Let the length of the altitude be 'h'. According to the problem, the altitude divides the hypotenuse into segments of lengths 6 and 9. Let's denote the lengths of these segments as 'x' and 'y', respectively.

Using the properties of similar triangles, we can set up the following proportion:

h / x = y / (x + y)

Cross-multiplying the proportion:

h(x + y) = xy

Expanding:

hx + hy = xy

Rearranging the equation:

hx - xy = -hy

Factoring out 'h':

h(x - y) = -hy

Dividing both sides by (x - y):

h = -y

From the given information, we know that the lengths of the segments are 6 and 9. So, we substitute x = 6 and y = 9 into the equation:

h = -(9)

h = -9

The length of the altitude is 9 units.

Undamped forced oscillation and Beats Phenomenon Undamped forced oscillation:In an undamped forced oscillation, the amplitude of oscillation can become very large if the driving force is close to the natural frequency of the oscillator. Such oscillations are observed, for example, in the vibrations of a guitar string when it is plucked.

The energy input from the plucking causes the string to vibrate at its natural frequency.Beats phenomenon:Beats are the oscillations that result when two sound waves of slightly different frequencies interfere with one another. They are the result of the difference between the frequencies of the two waves. Beats are commonly observed in music and are a fundamental concept in sound and acoustics.

Now, let's find the solution of the given initial value problem:The given equation is x''+33.64x=4cos(6t) with x(0)=0 and x'(0)=0.To solve this, first, we need to find the homogeneous solution, xh(t) by solving the auxiliary equation as:r²+33.64=0r = ±√(-33.64) = ±5.8jAs the roots are imaginary, the general solution for the homogeneous equation is:xh(t) = c1cos(5.8t) + c2sin(5.8t)where c1 and c2 are constants.
