The exponential function that passes through the two points given is (a) f(x) = 4(2ˣ) and (b) g(x) = (9^(2/5)) ((1/9)^(1/5))ˣ.

1. Use the general form of an exponential function: f(x) = abˣ
2. Plug in the x and y values from the first point into the equation and solve for b.
3. Plug in the x and y values from the second point and the value of b into the equation and solve for a.
4. Substitute the values of a and b back into the general equation to get the formula for the function.

For point a:

1. f(x) = abˣ
2. 2 = ab⁻¹
3. 64 = ab⁴
4. Divide the equations to eliminate a: (64/2) = (ab⁴)/(ab⁻¹) = b⁵
5. Solve for b: b = 2
6. Substitute b back into one of the equations and solve for a: 2 = a(2)⁻¹ = a/2, a = 4
7. Substitute a and b back into the general equation: f(x) = 4(2)ˣ

For point b:

1. g(x) = abˣ
2. 9 = ab⁻³
3. 1 = ab²
4. Divide the equations to eliminate a: (1/9) = (ab²)/(ab⁻³) = b⁵
5. Solve for b: b = (1/9)^(1/5)
6. Substitute b back into one of the equations and solve for a: 9 = a((1/9)^(1/5))⁻³ = a(9^(3/5)), a = 9^(2/5)
7. Substitute a and b back into the general equation: g(x) = (9^(2/5))((1/9)^(1/5))ˣ

So the formulas for the exponential functions are:
f(x) = 4(2)ˣ
g(x) = (9^(2/5)) ((1/9)^(1/5))ˣ

Answer:

One possible way to complete the array is:

    8  |  2 0 8

       |

    ------

       |

 2 |  2 6

 5 |  5 2

 1 |  1 7

 6 |  2 0

The answer is 26, so 208 ÷ 8 = 26.

To complete the array, we start by dividing the hundreds digit (2) by 8, which gives 0 with a remainder of 2. We write the remainder (2) in the ones place of the first row. Then we bring down the tens digit (0) and add it to the remainder to get 20. We divide 20 by 8, which gives 2 with a remainder of 4. We write the remainder (4) in the tens place of the second row, and bring down the ones digit (8) to the ones place of the second row. Finally, we add the digits in the second row to get 26, which is the quotient of the division

Step-by-step explanation:

The real zeros of this function are 0 (multiplicity 4),-8 (multiplicity 2), and 2 (multiplicity 4).

The real zeros of the function occur when any of the factors is equal to zero:

x^(4) = 0, (x-2)^(4) = 0, or (x+8)^(2) = 0

To find the real zeros of the given function, we need to set the function equal to zero and solve for x:

f(x) = x^(4)(x-2)^(4)(x+8)^(2) = 0

The process to find these zeros is as follows:

1. Set f(x) = 0 and solve for x

2. Factor the polynomial and solve each factor:

f(x) = 0 => x^(4)(x-2)^(4)(x+8)^(2) = 0
           => x4 = 0
           => x = 0 (multiplicity 4)

           => (x-2)4 = 0
           => x = 2 (multiplicity 4)

           => (x+8)2 = 0
           => x = -8 (multiplicity 2)

The multiplicity of a zero is the number of times it appears as a factor in the function. In this case, the zero 0 has a multiplicity of 4, the zero 2 has a multiplicity of 4, and the zero -8 has a multiplicity of 2.

Therefore, the real zeros and their multiplicities are:
0 with a multiplicity of 4
2 with a multiplicity of 4

-8 with a multiplicity of 2

Answer: -14.9 and 2.1

Step-by-step explanation:

If you take -6.4 - 8.5 in one direction you get -14.9 .

And if you add them together (-6.4 + 8.5) you get 2.1,

those are two possible values depending on if you add or subtract the 8.5 .

Answer:

Your answer is x = 7.

Step-by-step explanation:

<HFG + <YFG = 180°

180° - <HFG = <YFG

<H + <G + <HFG = 180°

<H + <G  = 180° - <HFG

<H + <G  = <YFG

(6x + 8) + (65°)  = (3+16x)

6x + 8 + 65 = 16x + 3

Get x on one side and the other numbers on the other side.

8 + 65 - 3 = 16x - 6x

70 = 10x

x = 7

You can plug in x into the angle to solve for their angles.

Answer:

x = 7

Step-by-step explanation:

∠HFG must equal to 180° - ∠YFG. Because there are 180° in a triangle, we can subtract the known value, 65°, and be left with 115°.

From there, an equation can be formed.

115° = 6x + 8 + 180 - (3+16x)

115°= 6x + 188 - 3 - 16x

115°= 185 - 10x

-70° = -10x

a) The annual simple interest rate for this transaction is 16%.

b) Wolfgang paid $3,000 for the loan.

The annual simple interest rate is the percentage of the principal amount that is charged as interest for one year. It can be calculated using the formula I = P*R*T, where I is the interest, P is the principal amount, R is the annual interest rate, and T is the time in years.

(a) In this case, the principal amount is $2,500, the interest is $2,700 - $2,500 = $200, and the time is 180/360 = 0.5 years. We can plug these values into the formula and solve for R:

$200 = $2,500*R*0.5

$200 = $1,250*R

R = $200/$1,250

R = 0.16

The annual simple interest rate for this transaction is 16%.

(b) To find out how much Wolfgang paid for the loan, we can use the same formula and solve for P. The interest is $2,700 - $2,500 = $200, the annual interest rate is 20%, and the time is 120/360 = 0.3333 years:

$200 = P*0.20*0.3333

$200 = 0.06666*P

P = $200/0.06666

P = $3,000

Wolfgang paid $3,000 for the loan.

The image of the figure under a dilation with scale factor 3/2 is attached

From the question, we have the following parameters that can be used in our computation:

Center = (0, 0).

Point = (6, 12), (8, 12) and (8, 8)

Scale factor = 3

A dilation with center (0, 0) and scale factor k multiplies the coordinates of a point by k.

So, to find the image of the point under the dilation with scale factor 3/2, we multiply each coordinate by 3/2:

Image = [(6, 12), (8, 12) and (8, 8)] * 3/2

Jaylon and Paula should expect the pointer to land on 4 around 30 and 43 times respectively.

A probability calculated by a series of tests is known as experimental probability.

The given table is as follows:

              1    2    3    4

Jaylon:   6    8    9    7

Paula:    8     5     7   10

To determine the experimental probability of the pointer landing on 4 for Jaylon, we add up the number of times the pointer landed on 4 for Jaylon and divide by the total number of spins:

Experimental probability for Jaylon = (number of times the pointer landed on 4 for Jaylon) / (total number of spins)

= 7 / 30

Similarly,

Experimental probability for Paula:

= 10 / 30

Expected number of times the pointer will land on 4 = (experimental probability) x (total number of spins)

For Jaylon: (7 / 30) × 130 = 30.33

The coordinates of A' and B' after a dilation with a scale factor of 2 with a center point of dilation at the origin is: OA (-8, 2) and B (-2, 6)

To find the coordinates of A' and B' after a dilation with a scale factor of 2 with a center point of dilation at the origin, we can use the following formula:

A' = k * (A - O) + O

B' = k * (B - O) + O

where k is the scale factor, O is the center point of dilation, and A and B are the original points.

In this case, k = 2 and O = (0, 0). So we have:

A' = 2 * (-4, 1 - (0, 0)) + (0, 0) = (-8, 2)

B' = 2 * (-1, 3 - (0, 0)) + (0, 0) = (-2, 6)

The radius of the first circle is 14.67 cm and the radius of the second circle is 8.11 miles.

The radius of a circle can be found by using the formula s = rθ, where s is the length of the arc, r is the radius, and θ is the central angle in radians. Rearranging the formula, we can find the radius by dividing the length of the arc by the central angle: r = s/θ.

For the first part of the question, we are given an arc length of 88 cm and a central angle of 6 radians. Plugging these values into the formula, we can find the radius:

r = 88 cm / 6 radians = 14.67 cm

For the second part of the question, we are given an arc length of 17 miles and a central angle of 120°. However, we need to convert the central angle from degrees to radians before plugging it into the formula. We can do this by multiplying the angle in degrees by π/180:

120° × π/180 = 2π/3 radians

Now we can plug the values into the formula to find the radius:

r = 17 miles / (2π/3) radians = 8.11 miles

So the radius of the first circle is 14.67 cm and the radius of the second circle is 8.11 miles.

Consider the expression |x+3|5x-2|-(x+3)(4x+3)|. To rewrite this expression in the form (x+3)|ax+b|, we will need to use the distributive property and combine like terms.

First, let's distribute the (x+3) term:

|x+3|5x-2| - (x+3)(4x+3) = |5x^2 + 13x - 2| - |4x^2 + 15x + 9|

Next, let's combine like terms:

|5x^2 + 13x - 2| - |4x^2 + 15x + 9| = |x^2 - 2x - 11|

Now, we can factor the expression inside the absolute value:

|x^2 - 2x - 11| = |(x+3)(x-5)|

Finally, we can rewrite the expression in the form (x+3)|ax+b|:

|(x+3)(x-5)| = (x+3)|x-5|

Converting 4 feet and 11 inches is equivalent to 59 inches.

The metric system, which bases measurements on the metre for length and kilogramme for mass, was first used in France in 1795. Following the French Revolution, the government tasked scientists with finding a replacement for the nation's dozens of distinct conventional measurement methods. The metre was created by measuring a quadrant of the Earth's circumference that passes through Paris on its way from the North Pole to the Equator. All measurements were made using the new unit, called a metre, which was approximately thirty-nine inches in length.

We know that,

1 foot is equal to 12 inches.

Thus,

4 feet = 4 × 12 inches = 48 inches

Add the 11 inches to get the total:
