What is the base of the exponent in the function f(x)=3(8√3) 2x when the function is written using only rational numbers and is in simplest form?

The answer of the given question based on the graph and the function the answer are,

a) Demi's speed is decreasing over time.

b) Demi's speed decreases  from approximately 8.5 miles per hour to 5 miles per hour and  Demi's speed decreases from approximately 6 miles per hour to 3 miles per hour.

Speed is measure of how fast object is moving, or  rate at which it covers  certain distance over time. Mathematically, speed is calculated as distance traveled divided by time it takes to travel that distance.

a. When the function is decreasing, Demi's speed is decreasing over time. This means that she is running more slowly as time goes on. On the graph, this will be shown as a downward slope or a negative slope. The steeper the slope, the faster her speed is decreasing.

b. From the graph, we can see that the function is decreasing in two intervals. The first interval is from 0 to 5 minutes, where Demi's speed decreases from approximately 8.5 miles per hour to 5 miles per hour. The second interval is from 10 to 15 minutes, where Demi's speed decreases from approximately 6 miles per hour to 3 miles per hour.

Roderick earns an interest of $30 per year for every $500 deposited in his savings account. This means that the interest rate per $500 deposit is:Interest rate per $500 = $30/$500 = 0.06 or 6%To calculate the interest earned on Roderick's savings account, we first need to determine how many $500 deposits he has. We can do this by dividing his total savings by $500:Number of $500 deposits = $1,250/$500 = 2.5

Answer:

Step-by-step explanation:

To find the LCM of the given expressions, we need to factor each expression completely and then find the product of the highest powers of all the factors.

ax² - (a² + ab)x + a²b can be factored as:

ax² - (a² + ab)x + a²b = a(x - b)(x - a)

bx² - (b² + bc)x + b²c can be factored as:

bx² - (b² + bc)x + b²c = b(x - c)(x - b)

cx² - (c² + ac)x + c²a can be factored as:

cx² - (c² + ac)x + c²a = c(x - a)(x - c)

Now, the LCM is the product of the highest powers of all the factors.

The highest power of a is a², the highest power of b is b², and the highest power of c is c². So, the LCM is:

LCM = a²b²c²(x - a)(x - b)(x - c)

Therefore, the LCM of ax² - (a² + ab)x + a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x + c²a is a²b²c²(x - a)(x - b)(x - c).

Answer:

Step-by-step explanation:

To calculate this, we need to use the formula for future value of an annuity:

FV = PMT x ((1+i)^n - 1)/i

Where:

PMT = the periodic payment (or deposit)

i = the interest rate per period

n = the number of periods

In this case, there are three deposits:

- R3,600 deposited one year ago

- R5,000 deposited today

- R7,500 to be deposited next year

We can calculate the future value of each of these deposits separately, and then add them together to get the total future value:

Future value of R3,600 deposited one year ago:

n = 4 (4 years until the equipment purchase)

i = 7% per year

PMT = R3,600

FV = R3,600 x ((1+0.07)^4 - 1)/0.07 = R4,661.07

Future value of R5,000 deposited today:

n = 3 (3 years until the equipment purchase)

i = 7% per year

PMT = R5,000

FV = R5,000 x ((1+0.07)^3 - 1)/0.07 = R6,885.02

Future value of R7,500 to be deposited next year:

n = 2 (2 years until the equipment purchase)

i = 7% per year

PMT = R7,500

FV = R7,500 x ((1+0.07)^2 - 1)/0.07 = R8,733.63

Total future value = R4,661.07 + R6,885.02 + R8,733.63 = R20,279.72

Therefore, there will be R20,279.72 available when the family is ready to buy the equipment, assuming a 7% rate of return on the investment.

Step-by-step explanation:

You want to know which set of equations could be combined in such a way as to result in the equation 3x = 18.

To obtain a term of 3x, the second equation must be subtracted from the first. That will result in 3x +2y = 18, not the equation of interest.

A term of 3x can be obtained by adding twice the first equation to the second:

  2(x +y) +(x -2y) = 2(4) +(10)

  3x = 18 . . . . . as required

A term of 3x can be obtained by subtracting the second equation from the first. That will result in 3x +2y = 18, not the equation of interest.

These equations are dependent. The second is the opposite of the first. They have an infinite number of solutions, not the single solution of the system of equations of interest.

A number pyramid puzzle is a type of mathematical puzzle where a pyramid-shaped grid of numbers is given, with some of the numbers missing.

Check the attached image for labeling. Since each number is the product of the two numbers directly beneath it. We can say:

m = -4 * 0.5 = -2

k = 0.5 * 1/8 = 1/16

x * (-1/8) = 8

x = 8/(-1/8)

x = -64  

y = x * 1/8

y = -64 * 1/8

y = -8

j = m * k

j =  -2 * 1/16 = -1/8

p = -48 * m

p = -48 * (-2) = 96

n = y * 8

n = -8 * 8 = -64

t = p * j

t = 96 * (-1/8) = -12

w = -1/2 * n

w = -1/2 * (-64) = 32

c = t * 1/16

c = -12 * 1/16 = -3/4

u = 1/16 * w

u = 1/16 * 32 = 2

The calculated value of the force of the resistance is 15.62 N

We can use Newton's Second Law of Motion to solve this problem. The formula is:

F = m*a

where F is the net force, m is the mass of the object, and a is the acceleration.

In this case, the brick is falling through water, so there are two forces acting on it:

The net force is the difference between these two forces:

F_net = F_gravity - F_resistance

The weight of the object is:

F_gravity = m*g

So, we have

F_gravity = 2 kg * 9.81 m/s^2 = 19.62 N

Now we can use the formula for net force to find the force of water resistance:

F_net = F_gravity - F_resistance

F_resistance = F_gravity - F_net

F_resistance = 19.62 N - m*a

This gives

F_resistance = 19.62 N - 2 kg * 2 m/s^2 = 15.62 N

Therefore, the force of water resistance is 15.62 N.

Answer:

To find all values of x for which f(x) = 26, we can set up the equation:

8x + 15/x = 26

Multiplying both sides by x, we get:

8x^2 + 15 = 26x

Bringing all the terms to one side, we get:

8x^2 - 26x + 15 = 0

We can factor this quadratic equation using the factoring method or by using the quadratic formula. Here, we will use the factoring method:

8x^2 - 26x + 15 = 0

(4x - 3)(2x - 5) = 0

Setting each factor equal to zero and solving for x, we get:

4x - 3 = 0 OR 2x - 5 = 0

4x = 3 OR 2x = 5

x = 3/4 OR x = 5/2

Therefore, the values of x for which f(x) = 26 are x = 3/4 or x = 5/2.

There is a significant linear correlation (r=0.80) between the heights of winning candidates and runners-up in recent US presidential elections.

Using the data from the table, here are the steps to determine the correlation coefficient and test for a linear correlation:

Calculate the correlation coefficient (r) using the formula: r = (nΣXY - ΣXΣY) / sqrt[(nΣX² - (ΣX)²)(nΣY² - (ΣY)²)], where n is the sample size, X and Y are the two variables (heights of candidates who won and runners-up), Σ denotes the sum of the values, and sqrt is the square root function.

Using a spreadsheet, we get r = 0.80.

Using the formula: df = n - 2.

The sample size (n) is 10, so df = 10 - 2 = 8.

Find the critical values of r using a table or calculator based on the degrees of freedom and the desired level of significance (0.05).

For a two-tailed test with df = 8 and α = 0.05, the critical values are ±0.632.

Since |0.80| > 0.632, we can conclude that there is a significant linear correlation between the heights of winning candidates and runners-up.

Therefore, the correlation coefficient is 0.80, and the critical values are ±0.632. There is a significant linear correlation between the heights of winning candidates and runners-up in recent presidential elections.

Answer: sorry I can't see it.

Step-by-step explanation:

We have shown that ΔABC ~ ΔDBE because the corresponding angles are congruent and the corresponding sides are proportional.

The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well.

We must demonstrate that the respective angles of the two triangles are congruent and the corresponding sides are proportionate in order to demonstrate that ABC DBE.

To begin with, we can relate the sides of the two triangles using the following equation AB BE = CB BD. Let x, y, and z all be equal to AB. Next, we have:

x · BE = y · z (substituting the given values)

y/x = BE/BD (dividing both sides by BD and then by x)

Now, we can utilise the knowledge that a triangle's angles sum to 180 degrees to get the length of ABC:

ACB - 180° = ABC (from the given triangle ABC)

ABC = 180 degrees - BDE (corresponding angles)

The measure of BDE can then be determined using the connection between the sides that we discovered earlier:

y/x = BE/BD (from above)

BE/DE = y/(x+z) (substituting z = BD)

BDE is equal to tan(y/(x+z)) Inverse tangent is used.

Now, we can use the fact that a triangle's angles sum to 180 degrees to determine the size of the DBE:

DBE = 180°, BDE, and BED

DBE is equal to 180 - tan(y/(x+z)) - ∠BED (substituting the angle measure we just found) (substituting the angle measure we just found)

DBE is equal to 180° - tan(y/(x+z)) - tan(y/z) (using inverse tangent again)

tan(z(y+x)/(xz-yz)) = DBE (using the tangent of the sum formula)

In order to demonstrate that the sides of the two triangles are proportional, we can once more use the relationship between the sides:

BE/BD = AB/CB (from the given equation and simplification)

Y/x = AB/CB (from the relationship between the sides)

As a result, we have demonstrated that ABC DBE since the associated angles and sides are congruent and proportionate, respectively.
