If (6 to the 0 power ) to x power = 1, what are the possible values of x? Explain answer
The value of x can be any real number because raising 1 to any exponent will always result in 1.
The question needs us to solve for x in the equation [tex](6 to the 0 power)^x[/tex]= 1. We know that any non-zero number raised to the 0 power is 1 (e.g.,[tex]10^0[/tex] = 1). Thus, 6 to the 0 power is 1 regardless of the value of 6. From this, we have[tex]1^x[/tex], which is still 1 for any value of x because 1 raised to any power is always 1. Hence, the equation remains true for any real number value of x.

Answer:
g(f(x)) = x
Step-by-step explanation:
You are given f(x) = -4x - 1 and g(x) = [tex]\frac{x+1}{-4}[/tex]. Keep in mind that f(x) or g(x) is the same as a y = equation, but two separate equations.
You are trying to find g(f(x)), which means that you will use f(x) and substitute this value into the x value in the equation of g(x).
It will look like: g(-4x - 1) = [tex]\frac{x+1}{-4}[/tex]
[tex]\frac{(-4x-1)+1}{-4}[/tex]
Now evaluate the expression to solve the problem. Start by combining like terms.
[tex]\frac{(-4x)}{-4}[/tex]
You are left with -4x/-4. We can simplify this even further by dividing both sides of the fraction by -4/-4. The -4's cancel out and become 1's, so you are left with:
[tex]x[/tex]
Answer:
Step-by-step explanation:
g(f(x)) means that wherever you see an x in g(x) you put f(x) in it's place. Read that sentence a couple of times until it makes sense.
g(x) = (x + 1)/-4
g(f(x)) = (f(x) + 1) / - 4 Now wherever you see f(x), put in -4x - 1
g(f(x)) = [(-4x - 1) + 1] / - 4 Remove ( )
g(f(x)) = [-4x - 1 + 1 ] / - 4
g(f(x)) = [-4x] / - 4 Do the division
g(f(x)) = x

You invest 23,400 annual interest rate of 4% compounded annually for seven years what is the balance of the account at the end of that time
Answer: 30792.80
=====================================
Work Shown:
We deposit P = 23400 dollars for t = 7 years, which is compounded n = 1 times per year at an interest rate of r = 4% = 0.04 (we'll use the decimal form of the interest rate)
So this means...
A = P*(1+r/n)^(n*t)
A = 23400*(1+0.04/1)^(1*7)
A = 23400*(1+0.04)^(7)
A = 23400*(1.04)^(7)
A = 23400*1.31593177923584

The formula for converting Celsius temperatures to Fahrenheit temperatures is a linear equation. Water freezes at 0 °C, or 32 °F, and it boils at 100 °C, or 212 °F. Find the slope and y-intercept for a graph that gives degrees Celsius on the horizontal axis and degrees Fahrenheit on the vertical axis. Then write an equation in slope-intercept form that converts degrees Celsius into degrees Fahrenheit.
The equation for converting a Celsius temperature into a Fahrenheit one is given by the linear equation F = 1.8C + 32. The slope of this equation is 1.8 and the y-intercept is 32.
Explanation:
The subject of this question is Mathematics, specifically the study of linear equations. To find the slope and the y-intercept of the equation that transforms a Celsius temperature into a Fahrenheit one, we can use the two points you provided: (0, 32) and (100, 212). The slope can be calculated as follow: (212 - 32) ÷ (100 - 0) = 180 ÷ 100 = 1.8. The y-intercept is the Fahrenheit temperature when the Celsius temperature is zero, so it's 32. Therefore, the equation you are looking for in slope-intercept form is: F = 1.8C + 32, where F is the temperature in Fahrenheit and C is the temperature in Celsius.

What are the zeros of the polynomial function f(x)=x^3+2x^2-24x?
Immediately, we can factor an x out of each term to simplify the polynomial.
x(x^2 + 2x - 24)
In doing this, we know the first zero will be x = 0.
Using the AC method, we can find the next two zeros.
x(x - 4)(x + 6)
The zeros, or x-intercepts of the polynomial, are 0, 4, and -6.The zeros of the polynomial function f(x) = x^3 + 2x^2 -24x are x = -6, 0, and 4.
Explanation:The question requires finding the zeros of the polynomial function f(x) = x^3 + 2x^2 -24x. The zeros of this function can be found by setting the function equal to zero and solving for x. So, we have 0 = x^3 + 2x^2 - 24x. All terms have an 'x', so we can factor out 'x' to give: 0 = x (x^2 + 2x - 24). The quadratic formula (which is used for expressions of the form ax^2 + bx + c = 0) to solve x^2 + 2x - 24 = 0, we get x = -6 and x = 4. Therefore, the zeros of the function are x = -6, 0, and 4.

A scientist builds a Mars rover that can travel 4.9 centimeters per second on flat ground. If the rover continues at the same rate, how many centimeters will it travel in 15 1/2 seconds?
Answer:
The rover would travel 75.95 centimeters in 15 1/2 seconds.
Step-by-step explanation:
Simply multiply 4.9 by 15 1/2.
Hope it helps!
Answer:
75.95 cm
Step-by-step explanation:
We know that distance = rate times time
d =rt
We know the rate = 4.9 cm/s
and time = 15 1/2 s = 15.5 s
Substituting these into d=rt
d = (4.9 cm/s) * 15.5 s = 75.95 cm
In the first week students at RSM solved 25 percent of their monthly quota of problems. In the second week, they solved 110 percent of the number of problems solved in the first week. In the third week they solved 60 percent of the number of problems they had solved in the first two weeks and, in the fourth week, they solved the remaining 320 problems. How many problems did students solve in the four-week month?
Answer:
The number of problems solved = 2000
Step-by-step explanation:
Let us assume the monthly quota of problems be x
number of problem solved in first week = 25 % of x =[tex]0.25x[/tex]
number of problems solved in 2nd week = 110% of (problems solved in 1st week)
= [tex]1.10 (0.25x)[/tex]
=[tex]0.275x[/tex]
number of problem solved 3rd week= 60% of ( problems solved in 1st and 2nd week)
= [tex]0.60(0.25x+0.275x)[/tex]
=[tex]0.60(0.525x)[/tex]
=[tex]0.315x[/tex]
number of problem solved in 4th week = [tex]320[/tex]
now we have
number of problems solved in ll 4 weeks = x
[tex]0.25x +0.275x+0.315x+320=x[/tex]
[tex]0.84x+320=x[/tex]
[tex]320=x-0.84x[/tex]
[tex]320=0.16 x[/tex]
[tex]x=\frac{320}{0.16}[/tex]
[tex]x=2000[/tex]
Hence the number of problems solved = 2000
Final answer:
In the third week they solved 60% of the number of problems they had solved in the first two weeks and, in the fourth week, they solved the remaining 320 problems. The total number of problems solved in the four-week month is 492.
Explanation:
To solve this problem, we need to find the number of problems solved in each week and then add them together to get the total number of problems solved in the four-week month.
In the first week, the students solved 25% of their monthly quota of problems. Let's say their monthly quota is 'x'. So, they solved 0.25x problems in the first week.
In the second week, they solved 110% of the number of problems solved in the first week. That means they solved 1.1 * 0.25x = 0.275x problems in the second week.
In the third week, they solved 60% of the number of problems they had solved in the first two weeks. So, they solved 0.6 * (0.25x + 0.275x) = 0.345x problems in the third week.
In the fourth week, they solved the remaining 320 problems. This means the total number of problems solved in the first three weeks is 0.345x, and we can set up the following equation to find x: 0.345x + 320 = x.
Solving this equation, we get x = 491.429. Since we can't have a fractional number of problems, we can round x up to 492. Therefore, the students solved a total of 492 problems in the four-week month.

what is the simplified version of 4b-7-3b+9
Answer: b+2
Step-by-step explanation:
4b-7-3b+9
b+2
Simplifying:
3b + -9 + -8b = 11
Reorder the terms:
-9 + 3b + -8b = 11
Combine like terms: 3b + -8b = -5b

Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + -5b = 11 + 9
Combine like terms: -9 + 9 = 0
0 + -5b = 11 + 9
-5b = 11 + 9
Combine like terms: 11 + 9 = 20
-5b = 20
Divide each side by '-5'.
b = -4
Simplifying
Answer: b = -4

Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
To determine how many days are equal to 42 hours, you divide 42 by 24 which results in 1.75. Therefore, 42 hours is equivalent to 1 and 3/4 days.
Explanation:In this mathematics problem, we are asked to convert 42 hours into a measurement of days. To begin with, we know that 1 day equals 24 hours. Therefore, to convert 42 hours into days we will divide 42 by 24.
The result of this division is 1.75. In terms of a day fraction, this value represents 1 and 3/4 days. As such, we can say that 42 hours is equivalent to 1 and 3/4 days.

The bank charged Travis a $20 fee because his balance dropped below $0. He knows that he currently had an outstanding charge for $7.85 that he had not recorded yet. How much money will Travis have to deposit into his account so that the outstanding charge does not create another bank fee
Final answer:
Travis must deposit $27.85 to cover the $7.85 outstanding charge and the previous $20 overdraft fee, to avoid further overdraft fees and bring his account balance back to at least $0.
Explanation:
Travis needs to not only cover the outstanding charge to avoid further overdraft fees but also bring his account balance back to at least $0. If Travis currently has an outstanding charge of $7.85, and overdraft fees are typically $35 or higher, it's clear that merely covering the charge won't be enough; he must also compensate for any negative balance incurred from previous overdraft fees.
Assuming the $20 fee has already been applied to his account and his balance is now at -$20 (not considering any other transactions that have taken place), Travis would need to deposit enough money to cover both the fee and the outstanding charge. Therefore, he would need to deposit a total of $20 (to bring his balance to $0) plus the $7.85 outstanding charge, which sums up to $27.85. By depositing this amount, Travis would avoid a second overdraft fee and any additional monetary penalties.
It is worth noting that financial literacy is essential to manage personal finances effectively and avoid potential overdraft situations which could lead to a cycle of fees and negative balances.
In a certain year, brand A of heart-rate watch cost $39.99 and brand B cost $59.99. A nonprofit community health organization purchased 34 heart-rate watches for use at a wellness center. If the organization spent $1619.66 for the watches, how many of each type did they purchase?
Answer:
Brand A = 21 heart-rate watches.
Brand B = 13 heart-rate watches.
Step-by-step explanation:
Let A be the number of Brand A heart watches and B be the number of Brand B heart watches.
We have been given that a nonprofit community health organization purchased 34 heart-rate watches for use at a wellness center.
We can represent this information in an equation as:
[tex]A+B=34...(1)[/tex]
We have been given that in a certain year, brand A of heart-rate watch cost $39.99 and brand B cost $59.99 and the organization spent $1619.66 for the watches.
We can represent this information in an equation as:
[tex]39.99*A+59.99*B=1619.66...(2)[/tex]
We will use substitution method to solve our system of equations.
From equation (1) we will get,
[tex]A=34-B[/tex]
Substituting [tex]A=34-B[/tex] in equation(2) we will get,
[tex]39.99*(34-B)+59.99*B=1619.66[/tex]
[tex]1359.66-39.99*B+59.99*B=1619.66[/tex]
[tex]-39.99*B+59.99*B=1619.66-1359.66[/tex]
[tex]20*B=260[/tex]
[tex]B=\frac{260}{20}[/tex]
[tex]B=13[/tex]
Therefore, the organisation purchased 13 heart-rate watches of brand B.
Now let us substitute B=13 in equation (1).
[tex]A+13=34[/tex]
[tex]A+13-13=34-13[/tex]
[tex]A=21[/tex]
Therefore, the organisation purchased 21 heart-rate watches of brand A.
