(0, 1)
(1, 64)
(3, 16)
(8, 0.5)
The ordered pairs lie on the graph of the exponential function is (3, 16).
What is Exponential Function?The formula f(x) = [tex]a^x[/tex]defines an exponential function, where x is the input variable as an exponent. The exponential curve is determined by the exponential function and the value of x.
We have,
f(x) = 180 (0.5[tex])^x[/tex]
Now, for x = 0,
So, f(x) = 128(0.5[tex])^0[/tex]
= 128(1)
= 128
Now, for x = 1,
f(x) = 128(0.5[tex])^1[/tex]
= 128(0.5)
= 256
Now, for x = 3,
f(x) = 128(0.5[tex])^3[/tex]
= 128(1/8)
= 16
So, the correct ordered pair is (3, 16).

An airplane flies 3/4 of a mile in 1/8 of a minute what is the airplane speed in miles per minute
Answer:
Step-by-step explanation:
Use proportions to figure this out. On the top you'll have miles and on the bottom you'll have minutes. I am going to change 3/4 to .75 and 1/8 to .125:
[tex]\frac{miles}{minute}:\frac{.75}{.125}[/tex]
We want to know how many miles per 1 minute that is. So we have the unknown on top in a new ratio, with 1 on the bottom:
[tex]\frac{miles}{minute}:\frac{.75}{.125}=\frac{x}{1}[/tex]
This second ratio is allowing us to calculate what the decimal ratio is in miles per 1 minute. Cross multiply to get
.125x = .75 so
x = 6 miles
That tells us that the decimal ratio is equivalent to 6 miles per minute
Kevin, while calculating his tax adjustments, notes that he can make adjustments of $3,435 for contributions to his retirement plan, $3,393 for business losses, and $1,128 for business expenses. If Kevin’s gross income is $45,942, what is his adjusted gross income?
a. $53,898
b. $40,242
c. $41,421
d. $37,986
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Amount of Kevin's gross income = $45942
Amount he contribute to his retirement plan = $3435
Amount he lost in business losses = $3393
Amount he incurred in business expenses = $1128
So, His adjusted gross income will be
[tex]45942-(3435+3393+1128)\\\\=45942-(7956)\\\\=\$37986[/tex]
Hence, his adjusted gross income is $37,986.
Hence, Option 'D' is correct.

Stephan' sculpture is 7/12 foot tall. He attaches it to a base that is 1/3 foot tall. How tall, in feet, is the sculpture with the base?
Final answer:
To find the total height of Stephan's sculpture with the base, we add the heights represented by fractions with a common denominator to get an overall height of 11/12 feet.
Explanation:
To determine the overall height of Stephan's sculpture with the base, we simply need to add the height of the sculpture to the height of the base. The sculpture is 7/12 foot tall and the base is 1/3 foot tall. To add these two fractions together, we need to find a common denominator, which is 12 in this case. So, we convert 1/3 foot into 4/12 foot. Now we can add the two fractions:
7/12 + 4/12 = 11/12 feet
Therefore, the combined height of the sculpture and the base is 11/12 feet.

Talia took the bus from her home to the bank and then walked back to her home along the same route. The bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. To determine the time, x, that it took Talia to walk home, she used the equation 40(0.9 – x) = 5x.
Talia took approximately 0.8 hours, or 48 minutes, to walk home.
Explanation:To determine the time it took Talia to walk home, we can solve the equation
40(0.9 – x) = 5x.

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in standard form.
7, -11, and 2 + 6i
f(x) = x4 - 53x2 + 468x - 3080
f(x) = x4 - 9x3 - 42x2 + 234x - 3080
f(x) = x4 - 117x2 + 468x - 3080
f(x) = x4 - 9x3 + 42x2 - 234x + 3080
The polynomial function of minimum degree with real coefficients that has the zeros 7, -11, and 2 + 6i is obtained by also including the conjugate zero 2 - 6i and multiplying the corresponding factors. The proper polynomial is found after multiplying these factors and simplifying, but the given options do not match the correct polynomial. There may be an error in the given options.
Explanation:To write a polynomial function of minimum degree with real coefficients given the zeros 7, -11, and 2 + 6i, we must remember that complex zeros in polynomials with real coefficients always come in conjugate pairs. Therefore, the conjugate of 2 + 6i, which is 2 - 6i, must also be a zero of the polynomial.
First, we write a factor for each zero: (x - 7), (x + 11), (x - (2 + 6i)), and (x - (2 - 6i)). Multiplying these factors together will give us the required polynomial:
(x - 7)(x + 11)((x - 2) - 6i)((x - 2) + 6i)After multiplying and simplifying these factors, and combining like terms, the polynomial function in standard form with these zeros and with real coefficients is:
f(x) = x´ - 9x³ + 42x² - 154x + 3080
However, none of the given options match the correct polynomial derived from the provided zeros. It's possible there was a mistake in the multiplication or combining like terms, or there is an error in the options provided.

Find the value of y in the sequence 2, 8, 3y +5,...
1. If the sequence was arithmetic
2. If the sequence was geometric
In an arithmetic sequence, the common difference is constant. In a geometric sequence, the terms are obtained by multiplying the previous term by a constant ratio. In this case, the value of y in the sequence is 3 for an arithmetic sequence and 9 for a geometric sequence.
Explanation:In an arithmetic sequence, the difference between consecutive terms is constant. To find the value of y in the sequence 2, 8, 3y + 5, we observe that the common difference is 8 - 2 = 6. Therefore, we can set up the equation 8 - 2 = 3y + 5 - 8 to solve for y. Simplifying, we get 6 = 3y - 3. Solving for y, we have y = 3.
In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio. To find the value of y in the sequence 2, 8, 3y + 5, we need to determine the common ratio. We can see that the ratio between 8 and 2 is 8/2 = 4. Therefore, we can set up the equation 8/2 = (3y + 5)/8 to solve for y. Simplifying, we get 4 = (3y + 5)/8. Multiplying both sides by 8, we have 32 = 3y + 5. Solving for y, we get y = 9.

Let f(x) = 8x3 - 28x + 61 and g(x) = 2x + 5. Find f(x) / g(x)
The result of the division is:
[tex]\[\boxed{4x^2 - 10x + 11 + \frac{6}{2x + 5}}\][/tex]
To find [tex]\( \frac{f(x)}{g(x)} \)[/tex] where [tex]\( f(x) = 8x^3 - 28x + 61 \)[/tex] and [tex]\( g(x) = 2x + 5 \)[/tex], we need to perform polynomial division.
Polynomial Division
1. Divide the leading term of the dividend by the leading term of the divisor:
[tex]\[ \frac{8x^3}{2x} = 4x^2 \][/tex]
2. Multiply the entire divisor by this result and subtract from the dividend:
[tex]\[ 8x^3 - 28x + 61 - (4x^2 \cdot (2x + 5)) = 8x^3 - 28x + 61 - (8x^3 + 20x^2) \][/tex]
Simplifying, we get:
[tex]\[ -20x^2 - 28x + 61 \][/tex]
3. Repeat the process with the new polynomial:
[tex]\[ \frac{-20x^2}{2x} = -10x \][/tex]
4. Multiply the entire divisor by this result and subtract:
[tex]\[ -20x^2 - 28x + 61 - (-10x \cdot (2x + 5)) = -20x^2 - 28x + 61 - (-20x^2 - 50x) \][/tex]
Simplifying, we get:
[tex]\[ 22x + 61 \][/tex]
5. Repeat the process again:
[tex]\[ \frac{22x}{2x} = 11 \][/tex]
6. Multiply the entire divisor by this result and subtract:
[tex]\[ 22x + 61 - (11 \cdot (2x + 5)) = 22x + 61 - (22x + 55) \][/tex]
Simplifying, we get:
[tex]\[ 6 \][/tex]
Putting it all together, we have:
[tex]\[\frac{f(x)}{g(x)} = 4x^2 - 10x + 11 + \frac{6}{2x+5}\][/tex]
So, the result of the division is:
[tex]\[\boxed{4x^2 - 10x + 11 + \frac{6}{2x + 5}}\][/tex]
