Part A: If (7^2)^x = 1, what is the value of x? Explain your answer. (10 points)

Alex777 [14]

Answers:Part A: The value of x is 0.Part B: X can be any real number.
In Part A, you have to first evaluate 7^2. This is 49. Now, write the equation 49^x = 1. We know that if you raise any number to 0, then the answer is 1.
In Part B, you have to first evaluate 7^0, that is 1. Now, we have the equation 1^x = 1. In this case, 1 raised to any exponent is still only 1. Imagine 1^17, this would be 1 times itself 17 times or just 1.
Therefore any number will work in Part B.

Adam wishes to have $20 comma 000 available in 18 years to purchase a new car for his son as a gift for his high school graduat

wel

Adam should invest $15516 after 18 years.

<u>Explanation:</u>

Given:

Amount(18) = $20000

Rate of Interest, r = 1.41%

Time, t = 18 years

n = 365 (compounded daily)

General equation of amount that is compounded daily:

$A(t) = A_0(1 + \frac{r}{n} )^n^t$

Solving for A₀:

$A_0 = \frac{A(t)}{(1+\frac{r}{n} )^n^t}$

Substituting the values:

$A_0 = \frac{20000}{(1 + \frac{0.0141}{365})^3^6^5^X^1^8 } \\\\A_0 = \frac{20000}{1.289}\\ \\A_0 = 15516$

Therefore, Adam should invest $15516 after 18 years.

I need help with this question! Thank you! :))<br> (question info below)

Stolb23 [73]

Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]

To find the equation's y-intercepts, you can rearrange the variables, and isolate/get y by itself

#1

cx + ay = b Subtract cx on both sides

ay = b - cx Divide a on both sides

$y=\frac{b}{a}-\frac{c}{a}x$ (0, $\frac{b}{a}$ ) is your answer

Do the same for the rest, and you should get:

#2 (0, $\frac{a}{b}$ )

#3 (0, $\frac{c}{b}$ )

#4 (0, $\frac{c}{a}$ )
