When two exponents are multiplied together the two exponents multiply.

Answer:

the answer is 0.00221184

Step-by-step explanation:

as we can see 3rd term is product of first two terms

4th term is product of third and second term

5th term is the product of fourth and third term

 the next term in the sequence which is the sixth term will be the product of fifth and fourth term

Answer:

The next term of geometric sequence is 0.025 which is the probability of dropped call.      

Step-by-step explanation:

We are given the following information in the question:

The probability of a customer experiencing a dropped call decreases formed the geometric sequence.

The geometric sequence is:

0.8, 0.4, 0.2, 0.1, 0.05

First term = a = 0.8

Common difference = r =[tex]\frac{a_{n}}{a_{n-1}} = \frac{0.4}{0.8} = \frac{1}{2}[/tex]

We have to find the next term of the geometric series to find the next probability.

Next term of sequence =

[tex]a_n = a_{n-1}\times r\\= 0.05\times \displaystyle\frac{1}{2}\\\\= 0.025[/tex]

Hence, the next term of geometric sequence is 0.025 which is the probability of dropped call.

The range always be the Y values

Answer:

1

Step-by-step explanation:

y = mx + b

y = 1/2 x - 1

y = 1/2 (4) - 1

y = 2 - 1

y = 1

When x = 4, the function y = (1/2)x - 1 evaluates to y = 1. This linear equation has a slope of 1/2 and a y-intercept of -1.

To find the value of the function y = (1/2)x - 1 when x = 4, you simply need to substitute x = 4 into the equation and solve for y:

y = (1/2)(4) - 1

y = 2 - 1

y = 1

So, when x = 4, the value of the function y is 1.

In a more general sense, this equation represents a linear function with a slope of 1/2 and a y-intercept of -1. The slope (1/2) represents the rate of change, meaning that for every unit increase in x, y increases by 1/2. The y-intercept (-1) is the value of y when x is 0.

When x = 4, as calculated above, y is 1. This means that if you were to plot this function on a coordinate plane, the point (4, 1) would lie on the graph.

Answer:

Final answer is [tex]-112\cdot\sqrt{2}a^5[/tex].

Step-by-step explanation:

Given expression is [tex](a-\sqrt{2})^8[/tex].

Now we need to find the fourth term of the given expression  [tex](a-\sqrt{2})^8[/tex]. So apply the nth term formula using binomial expansion.

exponent n=8

4th term means we use r=4-1=3

x=2, [tex]y=-\sqrt{2}[/tex]

rth term in expansion of [tex](x+y)^n[/tex] is given by formula:

[tex]\frac{n!}{\left(n-r\right)!\cdot r!}x^{\left(n-r\right)}\cdot y^r[/tex]

[tex]=\frac{8!}{\left(8-3\right)!\cdot3!}\cdot a^{\left(8-3\right)}\cdot\left(-\sqrt{2}\right)^3[/tex]

[tex]=\frac{8!}{5!\cdot3!}\cdot a^5\cdot\left(-2\sqrt{2}\right)[/tex]

[tex]=\frac{40320}{120\cdot6}\cdot a^5\cdot\left(-2\sqrt{2}\right)[/tex]

[tex]=56\cdot a^5\cdot\left(-2\sqrt{2}\right)[/tex]

[tex]=-112a^5\cdot\sqrt{2}[/tex]

Answer:

A. $4397.9

Explanation:

We are given that Kendra sold 200 shares and that the price per share was $22.1

This means that:

Total value = 200 * 22.1 = $4420

Now, we know that the broker charged 0.5% commission on the total value

This means that:

Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1

Therefore,

Kendra's return = Total value - broker's charge

Kendra's return = 4420 - 22.1 = $4397.9

Step-by-step explanation:

The volume of the conical perfume bottle is 77.38 cubic centimeters of perfume, answer D.

To calculate the volume of a conical perfume bottle, we use the formula for the volume of a cone, which is V = (1/3)
3.14r²h, where r is the radius and h is the height of the cone. Given the radius of 3.7 centimeters and a height of 5.4 centimeters, we calculate:

V = (1/3)
3.14 * (3.7 cm)² * 5.4 cm
= (1/3) * 3.14 * 13.69 cm2 * 5.4 cm
= (1/3) * 3.14 * 73.926 cm3
= 3.14 * 24.642 cm3
= 77.38 cubic centimeters

Therefore, the perfume bottle can hold approximately 77.38 cubic centimeters of perfume, which corresponds to answer choice D.

[tex]f(x)=2\sqrt x[/tex] is continuous on [0, 4] and differentiable on (0, 4), so the MVT holds. We have

[tex]f'(c)=\dfrac{f(4)-f(0)}{4-0}\implies\dfrac1{\sqrt c}=\dfrac{2\sqrt4}4=1[/tex]

[tex]\implies1=\sqrt c\implies \boxed{c=1}[/tex]

Answer:

x= 16/9

Step-by-step explanation:

[tex]f(x) = 2\sqrt{x}[/tex] is differentiable on [0,4] so the Mean Value Theorem For Integrals applies.

Average Value of the Integral:

[tex]\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx = \frac{1}{4-0} \int\limits^4_0 {2\sqrt{x} } \, dx[/tex]

After evaluating you will get  [tex]\frac{8}{3}[/tex]

Now, this is the average value so you still need to find the x-value using the original equation:

19/50 of the baseball caps in the store are blue and on sale.

Let's say there are a total of 100 baseball caps in the store. Then, 2/3 of them are blue, which is:

2/3 x 100 = 66.67 (approximately 67)

So, there are approximately 67 blue baseball caps in the store. Out of these, 4/7 are on sale, which is:

4/7 x 67 = 38 (rounded to the nearest whole number)

Therefore, there are approximately 38 blue baseball caps that are on sale in the store.

The fraction of baseball caps in the store that are blue and on sale is:

Answer:

The difference in investment between the smallest investor an largest investor is $40,000

Step-by-step explanation:

Let

x ---> the contribution of the smallest investor

y ---> the contribution of the middle investor

z ---> the contribution of the largest investor

we know that

x+y+z=140,000 -----> equation A

x/y=3/4 -----> y=(4/3)x ----> equation B

x/z=3/7 ----> z=(7/3)x ----> equation C

substitute equation B and equation C in equation A and solve for x

x+(4/3)x+(7/3)x=140,000

(14/3)x=140,000

x=140,000*3/14

x=$30,000

Find the value of y

y=(4/3)x ----> y=(4/3)(30,000)=$40,000

Answer:

B. f(-1)=6

C.  The domain of f(x) is the set {-2.-1,0,1,2,3,4,5,6}

Step-by-step explanation:

To find f(5) from the table means, the y-value that corresponds to x=5.

This value is 12.

This implies that:

f(5)=12

Also the y-value that corresponds to -1 is 6.

Hence f(-1)=6

The domain of f(x) are the set of all the x-values.

The domain is : {-2.-1,0,1,2,3,4,5,6}

The range for f(x) is the set of all the corresponding y-values.

From the table, the range is: {5,6,7,8,9,10,11,12,13}

Step-by-step Answer:

If trapezium DBCE is one-fourth of the area of the triangle ABC, that means that the area of triange ADE is (1 - 1/4) = three-fourth of ABC.

Since DE is parallel to BC, we can prove that triangles ADE and ABC are similar.

Similar triangles have corresponding sides proportional, and area is proportional to the square of the linear proportions.

From this we can conclude that

(DE/BC)^2 = 3/4

DE/BC = sqrt(3/4) = sqrt(3)/2

DE = sqrt(3)/2 * 20 = 10 sqrt(3) = 17.320508 cm (to 6 decimal places).

On the subject of similar figures/volumes, if we know the ratio of linear dimensions (such as the side of a cube) as k, then the ratio of AREA of similar squares would be k^2.

Example: A square would have a side of 8 (area=8^2=64), and a (similar) square has a side of 10 (area = 10^2= 100).  The

ratio of areas = 64/100 = (8^2/10^2) = (8/10)^2

Here 8/10 is the ratio of linear dimensions = k, and the ratio of areas is k^2 = (8/10)^2 = 64/100.

The same works for cubes (or similar volumes) where the volumes would be proportional to k^3.

Answer:

- 0.0625

Step-by-step explanation:

Again, I don't know of another way besides Calculus other than letting x = something very tiny.

When you use calculus, the answer approaches - 1/16 = - 0.0625 (I think). So we'll let x = 0.01 and see how that goes.

numerator: 1/(0.01 + 4) - 1/4

(0.24938 - 0.25) / 0.01

- 0.000623 / 0.01 = - 0.0623 which is  pretty close considering what I used for x. You could try it with 0.0001 which will get much closer.

[tex]f^{-1}(x)=\frac{x+2}{5}[/tex]

Step-by-step explanation:

To find the inverse of a function we need to interchange x and y an solve for y.

Since [tex]f(x)=y[/tex], then

[tex]f(x)=5x-2[/tex]

[tex]y=5x-2[/tex]

[tex]x=5y-2[/tex]

Add 2 to both sides

[tex]x+2=5y-2+2[/tex]

[tex]x+2=5y[/tex]

Divide both sides by 5

[tex]\frac{x+2}{5}=\frac{5y}{5}[/tex]

[tex]\frac{x+2}{5}=y[/tex]

[tex]y=\frac{x+2}{5}[/tex]

[tex]f^{-1}(x)=\frac{x+2}{5}[/tex]

We can conclude that the correct answer is B. f -1(x) = x + 2 / 5
