the measurement of an inscribed angle is half of the measure of the intercepted arc.
the inscribed angle is 110 degrees, so we multiply 110 by 2.
110*2 = 220 degrees
The measure of the intercepted arc is 220 degrees
220° is the measure of the intercepted arc

Find the exact length of the curve. y = 3 + 2x3/2, 0 ≤ x ≤ 1
The exact length of the curve [tex]\(y = 3 + 2x^\frac{3}{2}\)[/tex] over the interval [tex]\(0 \leq x \leq 1\)[/tex] is [tex]\(\frac{2}{27} (10\sqrt{10} - 1)\)[/tex].
To find the exact length of the curve [tex]\(y = 3 + 2x^\frac{3}{2}\)[/tex] over the interval [tex]\(0 \leq x \leq 1\)[/tex], we can use the formula for arc length of a curve:
[tex]\[ L = \int_{a}^{b} \sqrt{1 + \left(\frac{dy}{dx}\right)^2} dx \][/tex]
where a and b are the lower and upper bounds of the interval, respectively.
First, we need to find [tex]\(\frac{dy}{dx}\)[/tex], which represents the derivative of y with respect to x:
[tex]\[ \frac{dy}{dx} = \frac{d}{dx}(3 + 2x^\frac{3}{2}) = 0 + 3x^\frac{1}{2} = 3\sqrt{x} \][/tex]
Next, we substitute this derivative into the formula for arc length:
[tex]\[ L = \int_{0}^{1} \sqrt{1 + (3\sqrt{x})^2} dx = \int_{0}^{1} \sqrt{1 + 9x} dx \][/tex]
Now, we need to integrate [tex]\(\sqrt{1 + 9x}\)[/tex]L with respect to \(x\). We can do this by making a substitution. Let u = 1 + 9x, then du = 9dx and \(dx = \frac{du}{9}\). Substituting these into the integral, we get:
[tex]\[ L = \frac{1}{9} \int_{1}^{10} \sqrt{u} du \][/tex]
Now, we can integrate [tex]\(\sqrt{u}\)[/tex]:
[tex]\[ L = \frac{1}{9} \left[\frac{2}{3}u^\frac{3}{2}\right]_{1}^{10} = \frac{2}{27} \left[10^\frac{3}{2} - 1^\frac{3}{2}\right] \][/tex]
[tex]\[ L = \frac{2}{27} (10^\frac{3}{2} - 1) \][/tex]
[tex]\[ L = \frac{2}{27} (10\sqrt{10} - 1) \][/tex]
So, the exact length of the curve [tex]\(y = 3 + 2x^\frac{3}{2}\)[/tex] over the interval [tex]\(0 \leq x \leq 1\)[/tex] is [tex]\( \frac{2}{27} (10\sqrt{10} - 1) \)[/tex].
f(x) = 16x4 – 81 = 0 Select all of the zeroes of the function.
3/2
-3/2
3/2i
-3/2i
Here we want to find all the zeros of the function f(x) = 16*x^4 - 81.
The zeros are:
x = 3/2x = -3/2x = (3/2)*ix = (-3/2)*iFirst, for a given function f(x), we define the zeros as the values of x such that:
f(x) = 0.
Then we must solve:
f(x) = 16*x^4 - 81 = 0
Solving this for x leads to:
16*x^4 = 81
x^4 = 81/16
x^2 = ±√(81/16) = 9/4
x = ±√±(9/4) = ±3/2 and ±(3/2)*i
So there are 4 zeros, and these are:
x = 3/2x = -3/2x = (3/2)*ix = (-3/2)*iWhere the two complex zeros come from evaluating the second square root on -9/4.

Answer-
The first graph represents [tex]f(x)=2(3)^x[/tex]
Solution-
The given function is,
[tex]f(x)=2(3)^x[/tex]
Putting x = 1,
[tex]f(x)=2(3)^1=2(3)=6[/tex]
So, the point (x, f(x)) i.e (1, 6) must satisfy or lie on the curve of the function.

Write the standard form of the line that contains a y-intercept of -3 and passes through the point (3, 0). Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
The equation of the line in standard form that has a y-intercept of -3 and passes through the point (3, 0) is y = x - 3.
Explanation:The standard form of a line can be found using the formula y = mx +b, where 'm' is the slope and 'b' is the y-intercept. The y-intercept in this problem is -3, but we need to find the slope to complete the standard form of the line. Since our line passes through the point (3,0) and (0,-3), the slope, m, can be found by using the formula (y2-y1)/(x2-x1), which gives us a slope of 1. So the equation of our line in standard form is y = x - 3.

A. 5 5/64
B. 5 1/4
C. 5 5/16
D. 5 5/6
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
[tex]S_n=\sum^{\infty}_{n=1}4(\dfrac{1}{4})^{n-1}[/tex]
We need to find the value of S₄.
So, it means sum of 4 terms.
Here it form a geometric series:

r = [tex]\dfrac{1}{4}[/tex] = Common ratio
And sum of n terms whose ratio is less than 1 is given by
[tex]S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_4=\dfrac{4(1-\dfrac{1}{4}^{4})}{1-\dfrac{1}{4}}\\\\S_4=\dfrac{4(1-0.25^4)}{1-0.25}\\\\S_4=\dfrac{4(1-0.0039)}{0.75}\\\\S_4=5.3125\\\\S_4=5\dfrac{5}{16}[/tex]

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate of 2.5% per year and is compounded monthly, how long does it take you to earn $3,000 without depositing any additional funds?
(I know it's 119.954 years, but I have no idea how to get that)
Answer:
It take 119.954 years to earn $ 3000 without depositing any additional funds.
Step-by-step explanation:
Given:
Principal Amount, P = $ 150
Amount, A = $ 3000
Rate of interest, R = 2.5% compounded monthly.
To find: Time, T
We use formula of Compound interest formula,
[tex]A=P(1+\frac{R}{100})^n[/tex]
Where, n is no time interest applied.
Since, It is compounded monthly.
R = 2.5/12 %
n = 12T
[tex]3000=150(1+\frac{\frac{2.5}{12}}{100})^{12T}[/tex]
[tex]\frac{3000}{150}=(1+\frac{2.5}{1200})^{12T}[/tex]
[tex]20=(1+\frac{2.5}{1200})^{12T}[/tex]
Taking log on both sides, we get
[tex]log\,20=log\,(1+\frac{2.5}{1200})^{12T}[/tex]
[tex]1.30103=12T\times\,log\,(1.002083)[/tex]
[tex]T=\frac{1.30103}{12\times\,log\,(1.002083)}[/tex]
[tex]T=119.954[/tex]
Therefore, It take 119.954 years to earn $ 3000 without depositing any additional funds

What are the solutions of 4x4 – 4x2 = 8?
Final answer:
To find the solutions of the equation 4x^4 - 4x^2 = 8, we can rearrange the equation and solve the resulting quadratic equation. The solutions are x = ±√2.
Explanation:
To find the solutions of the equation 4x^4 - 4x^2 = 8, we can rearrange the equation to get 4x^4 - 4x^2 - 8 = 0. This is a quadratic equation in terms of x^2. We can solve this quadratic equation by factoring or by using the quadratic formula.
Factoring the equation, we get (2x^2 - 4)(2x^2 + 2) = 0. Setting each factor equal to zero, we have 2x^2 - 4 = 0 and 2x^2 + 2 = 0.
Solving each equation separately, we get x^2 = 2 and x^2 = -1. Taking the square root of both sides, we get x = ±√2 and x = ±i. Therefore, the solutions of the original equation are x = ±√2.

The sum of two numbers is 49 . the smaller number is 17 less than the larger number. what are the numbers?
Final answer:
To solve the student's algebra problem, we defined variables, set up an equation based on the given conditions, and then solved for the larger number. Ultimately, we found the two numbers to be 33 and 16.
Explanation:
The student asked a problem that involves finding two numbers given that their sum is 49 and the smaller number is 17 less than the larger number. To solve this problem, we will use algebra.
Let the larger number be x and the smaller number be x - 17. According to the problem, the sum of these two numbers is 49:
x + (x - 17) = 49
Combine like terms: 2x - 17 = 49
Add 17 to both sides: 2x = 66
Divide by 2: x = 33
Since the larger number is 33, the smaller number is 33 - 17, which is 16.
Therefore, the two numbers are 33 and 16.
