The answer is x=1. Just did the assignment
The equation is a complex exponentiation problem that can be solved by simplifying and rearranging the equation. By plugging in the given potential solutions, it can be determined that x = -1 is the correct answer.
Explanation:This equation is an exponential equation. You can start solving by simplifying the bases, as both bases are actually the 2, but to different powers (512 = 2^9 and 1/64 = 2^-6). The equation can be rewritten as (2^9)^x - 2 = (2^-18)x - 512. Simplifying this gives 2^(9x) - 2 = 2^(-18x) - 512. From the options given (x = -1, 0, or 1), we can plug these into the simplified equation to see which one gives a valid solution. Plugging these values in reveals that x = –1 is the valid solution to the equation. None of the other choices work out correctly.

w is partly constant and partly varies inversely as the square of t. when w=24, t=4 and when w=18, t=2.
i. determine the law connecting w and t
ii. find t when w = 46
To find the law connecting w and t, we establish w as partly constant and partly inverse to t squared. Using given values, we find constants k and c and then solve for t when w is 46.
The problem states that w is partly constant and partly varies inversely as the square of t. Given two sets of values for w and t, we can establish the relationship between them. Since the variation is inverse with respect to the square of t, we can write the relationship as:
w = k / t2 + c
where k is a constant of variation and c is the constant part of w. To find these constants, we use the given data points (24, 4) and (18, 2). Substituting these into the equation, we get two simultaneous equations:
24 = k / 42 + c18 = k / 22 + cSolving these will give us the values of k and c, which then allows us to find t when w = 46.
To solve for t when w = 46, we plug this value into our established equation and solve for t. We'll end up with a quadratic equation in terms of t that we need to solve to find the time t.
The time t (in minutes) for a small plane to climb to an altitude of h feet is given by t = 50 log10 (18000/(18000-h)) where 18000 feet is the plane's absolute ceiling. a. Determine the domain of the function appropriate for the context of the problem. b. Graph the function and identify any asymptotes. c. As the plane approaches its absolute ceiling, what can be said about the time required to further increase its altitude. d. Find the amount of time it will take for the plane to climb to an altitude of 4000 feet.
The domain of the function is restricted to the altitude of the plane, and the plane cannot exceed its absolute ceiling. The graph of the function will have a vertical asymptote at the absolute ceiling. As the plane approaches its absolute ceiling, the time required to further increase its altitude increases significantly. To find the time it will take for the plane to climb to a specific altitude, substitute the altitude into the equation and solve for time.
Explanation:a. The domain of the function is determined by the restrictions given in the problem. In this case, the domain represents the altitude of the plane. Since the plane's absolute ceiling is 18,000 feet, the altitude cannot exceed 18,000 feet. Therefore, the domain is 0 ≤ h ≤ 18,000.
b. To graph the function, we can plot points by substituting different values of h into the function and calculating the corresponding values of t. This will result in a smooth curve. Asymptotes occur when the function approaches certain values of h or t. In this case, the function has a vertical asymptote at h = 18,000, because the plane cannot climb beyond its absolute ceiling.
c. As the plane approaches its absolute ceiling of 18,000 feet, the time required to further increase its altitude increases significantly. This is because the logarithmic function in the equation has a slower growth rate as h approaches its limit.
d. To find the time it will take for the plane to climb to an altitude of 4000 feet, we can substitute h = 4000 into the equation t = 50 log10 (18000/(18000-h)) and solve for t.
find the inverse of the function and then determine whether the inverse is a function.

Evaluate 390mm to 13cm as a ratio in its lowest terms
To evaluate the ratio of 390mm to 13cm, we convert 13cm to 130mm and then simplify the ratio of 390mm to 130mm to its lowest terms, which is 3 : 1.
To evaluate the ratio of 390mm to 13cm, we first need to express these measurements in the same unit. Converting centimeters to millimeters is simple: there are 10 millimeters in 1 centimeter.
Therefore, 13cm is equivalent to 130mm. Now, we can write the ratio as 390mm : 130mm. To simplify this ratio to its lowest terms, we divide both numbers by the greatest common divisor, which is 130 in this case. The simplified ratio is therefore 3 : 1.
The generalized description is as follows: quantity (in old units) imes conversion factor = quantity (in new units). One must remember to simplify the ratio by dividing both the numerator and the denominator by their greatest common divisor, finalizing the answer without the '1' in the denominator when it's the only figure present.
A radio station gives away $15 to every 15th caller, $25 to every 25th caller, and free concert tickets to every 100th caller. When will the station first give away all three prizes to one caller? PLEASE HELP.
Answer:
The station first give away all three prizes to 300th caller.
Step-by-step explanation:
A radio station gives away $15 to every 15th caller, $25 to every 25th caller, and free concert tickets to every 100th caller.
To get the answer we need to calculate L.C.M. of 15, 25, 100.
15 = 3 x 5
25 = 5 x 5
100 = 2 x 2 x 5 x 5
LCM is = 2 x 2 x 3 x 5 x 5 = 300.
Hence, the station first give away all three prizes to 300th caller.

Kevin has had a checking account for a month. As he reconciles his account, Kevin notices that the dates on his check register do not match the dates on his account statement. He immediately calls the bank to find out what the problem is. What is the bank's likely response to Kevin?
A- "you obviously made a mistake and you should be careful"
B-"sorry we entered the wrong dates but thanks for telling us, we will fix it immediately"
C-"theres a serious problem with your account, please bring us all your records and info so we can check it"
D-"The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when its written"
The bank's likely response to Kevin's concern would be that checks are recorded on the date they are cashed, not on the date they are written, which explains the mismatch in dates Kevin observed. Balancing one's checkbook regularly is important for managing personal finances.
When Kevin has noticed that the dates on his check register do not match the dates on his account statement and contacts the bank, the bank's likely response will be "The date that the check is written is usually a few days before it is cashed. We record when it was cashed and you record when it's written." This is a common situation in personal finance and is related to the cash basis of accounting that most individuals use to manage their finances. The difference in dates arises because checks are processed and cleared by the bank on the date they are cashed, not on the date they are written. It's important for individuals to balance their checkbooks regularly to manage money, keep track of cash flow, and avoid overdraft fees.

Find all numbers such that a third of a number increased by half that number is at least 3 less than that same number.
Answer:
All the numbers are less than and equal to 18.
Step-by-step explanation:
To find : All numbers such that a third of a number increased by half that number is at least 3 less than that same number ?
Solution :
Let the number be 'x',
A third of a number is [tex]\frac{x}{3}[/tex]
Half that number is [tex]\frac{x}{2}[/tex]
3 less than that same number is [tex]x-3[/tex]
A third of a number increased by half that number is at least 3 less than that same number is written as,
[tex]\frac{x}{3}+\frac{x}{2}\geq x-3[/tex]
[tex]\frac{2x+3x}{6}\geq x-3[/tex]
[tex]\frac{5x}{6}\geq x-3[/tex]
[tex]5x\geq 6x-18[/tex]
[tex]5x-6x\geq -18[/tex]
[tex]-x\geq -18[/tex]
[tex]x\leq 18[/tex]
Therefore, all the numbers are less than and equal to 18.
The set of numbers such that a third of a number increased by half that number is at least 3 less than that same number are given as; x <= 18.
According to the question;
Let the numbers in question be represented as x.
In essence;
[tex] \frac{x}{3} + \frac{x}{2 } \geqslant x - 3[/tex]
[tex] \frac{5x}{6} \geqslant x - 3[/tex]
5x >= 6x - 18-x >= -18x <= 18Therefore, the set of numbers such that a third of a number increased by half that number is at least 3 less than that same number are given as; x <= 18.

How can x-2/3=5/6 be solved for x in one step?
x - 2/3 = 5/6
the only step needed is to add 2/3 to 5/6
2/3 + 5/6 = 1 1/2
x = 1 1/2
Answer:
the value of x is [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
we need to solve value of x for expression [tex]x-\frac{2}{3}=\frac{5}{6}[/tex]
[tex]x-\frac{2}{3}=\frac{5}{6}[/tex]
Add both the sides by [tex]\frac{2}{3}[/tex]
[tex]x-\frac{2}{3}+\frac{2}{3}=\frac{5}{6}+\frac{2}{3}[/tex]
take L.C.M both the side and simplify
[tex]x=\frac{3}{2}[/tex]
Hence, the value of x is [tex]\frac{3}{2}[/tex]
