The solution x = -30/7 is the value of the unknown number that satisfies the statement "eighteen more than 7 times a number is -12".

This question is incomplete, the complete question is:

Eighteen more than 7 times a number is -12, find the unknown number.

Given that, eighteen more than 7 times a number is -12.

Let's use "x" to represent the unknown number.

From the given information, we can use algebra to translate this sentence into an equation.

We start by using "7x" to represent the product of 7 times "x", and adding 18 to it:

7x + 18

Then, we set this expression equal to -12, since that's what the sentence told us the expression is equal to:

7x + 18 = -12

To solve for "x", we can first subtract 18 from both sides:

7x + 18 - 18 = -12 - 18

7x = -30

Then, we can isolate "x" by dividing both sides by 7:

7x/7 = -30/7

x = -30/7

Therefore, the value of the unknown number is x = -30/7.

a) The sum of the given series is 7 / (1 + 2z)

b) The domain of convergence is (-∞, -1/2) U (1/2, ∞).

The given series can be expressed as

7 – 14z + 28z^2 - 56z^3 + ...

This is a geometric series with first term (a) = 7 and common ratio (r) = -2z. The formula for the sum of an infinite geometric series is

sum = a / (1 - r)

Substituting the values of a and r, we get

sum = 7 / (1 + 2z)

So, the sum of the given series is 7 / (1 + 2z).

For the series to converge, the absolute value of the common ratio must be less than 1. That is,

|r| = |−2z| < 1

Simplifying this inequality, we get

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its energy of combustion is known very accurately (-26.43 kJ/g).

The calorimeter constant is -2873.5.

Determine the calorimeter constant of the calorimeter that had a temperature increase of 9.199 degrees Celsius when 3.500 g of benzoic acid was used.To determine the calorimeter constant, follow these steps:

Explanation:

1. Calculate the energy released by the benzoic acid combustion: Multiply the mass of benzoic acid by its energy of combustion.
Energy released = mass × energy of combustion
Energy released = 3.500 g × -26.43 kJ/g = -92.505 kJ

2. Convert the temperature increase to a change in energy: Multiply the temperature increase by the mass of benzoic acid.
ΔEnergy = temperature increase × mass of benzoic acid
ΔEnergy = 9.199°C × 3.500 g = 32.1965 J

3. Determine the calorimeter constant: Divide the energy released by the change in energy.
Calorimeter constant = Energy released / ΔEnergy
Calorimeter constant = -92.505 kJ / 32.1965 J

Note: We need to convert the units to be consistent, either to J or kJ.
1 kJ = 1000 J, so -92.505 kJ = -92505 J.

Calorimeter constant = -92505 J / 32.1965 J = -2873.5

The calorimeter constant is -2873.5.

We can state that for any value of x between -3 and 11, the corresponding value of h(x) will be between 1 and 25 because the function h has a domain of -3 x 11 and a range of 1 h(x) 25.

Indicates that the function h is not fixed and that its values change depending on the value of x.

Now, evaluate your options:

Option A h(-3) = -1 - This statement is false because the range of h(x) is stated to be between 1 and 25, so h(-3) cannot be less than 1.

OptionB h(13) = 18 - This statement cannot be true because h(x) is specified to have a range between -3 and 11, so h(13) is not defined.

OptionC h(2) = 16 - The statement may be accurate given that the value of h(x) for any x between -3 and 11 could range from 1 to 25, and there is no evidence to the contrary.

so, we can go ahead and pull that number in.

now we have to subtract the 3 to try and get as much as possible over on the other side to find t.

10=30t-5t^2

Step-by-step explanation:

h(t) = 3 + 30t - 5t²

the height is set to 13 meters.

since the ball will go up and then come back down again, we expect 2 points of time, when the ball is at 13 meters high. if any at all, by the way (keep that in mind for similar questions, the object might not even reach a certain height).

13 = 3 + 30t - 5t²

10 = 30t - 5t²

2 = 6t - t²

0 = -t² + 6t - 2

the general solution to a quadratic equation

ax² + bx + c = 0

is

x = (-b ±sqrt(b² - 4ac))/(2a)

in our case

x = t

a = -1

b = 6

c = -2

t = (-6 ±sqrt(6² - 4×-1×-2))/(2×-1) =

Given function: g(x) = 1 – 2x + [tex]3x^2[/tex]

To find the average rate of change of the function as x varies from 2 to 5.

Solution: We are given a function: g(x) = 1 – 2x + [tex]3x^2[/tex]

The average rate of change of the function as x varies from a to b is given by:

Average rate of change = f(b) - f(a) / b - a

Let a = 2 and b = 5

We have to find the average rate of change of g(x) as x varies from 2 to 5.

So, the average rate of change of g(x) is given by:

Average rate of change = g(5) - g(2) / 5 - 2

= [1 - 2(5) + 3([tex]5^2[/tex])] - [1 - 2(2) + 3([tex]2^2[/tex])] / 3

there are 6 red counters, 24 blue counters, and 5 green counters in the bag, based on the given information.  The given information provides us with the ratio of red to blue counters in a bag, which is 2:5. This means that for every 2 red counters in the bag, there are 5 blue counters.

Let the number of red counters in the bag be 2x, where x is a constant. Then, the number of blue counters in the bag is 5x. We are also given that there are 9 more blue counters than before, so the new number of blue counters is 5x + 9.

We know that there are 35 counters in total, so we can write an equation based on this information:

2x + 5x + 5x + 9 = 35

Simplifying this equation, we get:

12x + 9 = 35

Subtracting 9 from both sides, we get:

12x = 26

Dividing both sides by 12, we get:

x = 2.1667

Since we cannot have a fraction of a counter, we can round x up to 3.

Therefore, the number of red counters in the bag is 2x = 2(3) = 6, and the number of blue counters in the bag is 5x + 9 = 5(3) + 9 = 24.

Finally, we can find the number of green counters in the bag by subtracting the number of red and blue counters from the total number of counters:

35 - 6 - 24 = 5

So there are 5 green counters in the bag.
