Answer:

the question on top is right

Step-by-step explanation:

The total area of the solid figure is 90 square inches + 27sqrt(3) / 4 square inches.

To find the total area of the solid figure, we need to determine the areas of each face and then add them together.

The solid figure consists of a rectangular prism with dimensions 3" x 3" x 6" and a pyramid on top with an equilateral triangle base.

First, let's find the area of the rectangular prism. The rectangular prism has two identical square faces with side length 3" and four rectangular faces with dimensions 3" x 6". The total area of the rectangular prism can be calculated as:

Area of the square faces: 2 * (3" * 3") = 2 * 9 square inches

Area of the rectangular faces: 4 * (3" * 6") = 4 * 18 square inches

Total area of the rectangular prism: 2 * 9 + 4 * 18 = 18 + 72 = 90 square inches.

Next, let's find the area of the triangular pyramid. The base of the pyramid is an equilateral triangle with side length 3". The height of the pyramid is 3". The formula to find the area of an equilateral triangle is (sqrt(3) / 4) * (side length)^2. Plugging in the values, we have:

Area of the triangular pyramid: (sqrt(3) / 4) * (3" * 3") * 3" = (sqrt(3) / 4) * 9 * 3 = (sqrt(3) / 4) * 27 = 27sqrt(3) / 4 square inches.

Now, we can find the total area of the solid figure by adding the area of the rectangular prism and the area of the triangular pyramid:

Total area = Area of rectangular prism + Area of triangular pyramid

Total area = 90 square inches + 27sqrt(3) / 4 square inches.

Thus, the total area of the solid figure is 90 square inches + 27sqrt(3) / 4 square inches.

As given in the question,

Success of the given probability is represented by 'p'

value of the probability of the success 'p' is given by

p = 0.70

Here , x = 5

Probability for the geometric distribution is given by

P( X = x ) = p ( 1 - p )ˣ ⁻ ¹

Substitute the value to get the value of P(5) we have,

P ( X = 5) = ( 0.70 ) ( 1 - 0.70 ) ⁵⁻¹

⇒ P( 5 ) = ( 0. 70 ) ( 0.30 ) ⁴

Answer:

  b > 1

Step-by-step explanation:

You want to know the conditions on an exponential function that represents growth.

The value of 'b' in the exponential function y = a·b^x is called the "growth factor." Each time x increases by 1 unit, the value of y is multiplied by 'b'. If that product is increasing, the value of 'b' must be greater than 1.

The relation represents growth when b > 1.

An exponential function in the form \(y = ab^x\) represents growth when the base (b) is greater than 1.

In an exponential function of the form y = ab^x, the base (b) is a crucial component. The behavior of the function depends on the value of the base.

When the base (b) is greater than 1, it means that b is a positive number larger than 1. In this scenario, as the value of x increases, the value of \(b^x\) also increases exponentially. This results in the function \(y = ab^x\) exhibiting growth.

To better understand this growth behavior, let's consider an example. Suppose we have an exponential function \(y = 2^x\). As x increases from 0, the values of \(2^x\) will be as follows:

For x = 0, \(2^0\) = 1

For x = 1, \(2^1\) = 2

For x = 2, \(2^2\) = 4

For x = 3, \(2^3\) = 8

For x = 4, \(2^4\) = 16

As you can see, as x increases, the values of \(2^x\) grow exponentially. This demonstrates the growth behavior of exponential functions when the base is greater than 1.

It's important to note that when the base (b) is between 0 and 1 (exclusive), the exponential function will exhibit decay or decreasing behavior rather than growth.

In summary, an exponential function of the form \(y = ab^x\) represents growth when the base (b) is greater than 1. As x increases, the function values increase exponentially, indicating a growth pattern.

Answer:

625.5 cm^2

Step-by-step explanation:

The volume of a cone is

V = 1/3 B h

4170 = 1/3 B 20

4170 = 20/3 B

Multiply each side by 3/20

4170 *3/20 = B

625.5 = B

Hey there! I'm happy to help you!

The formula for the volume of a cone is V=1/3(πr²h). Now, to make it look ungibberishy and all numbery...

The volume of the cone is equal to the area of the base (the circle on the bottom whose area formula is pi multiplied by the radius squared) multiplied by the height and then divided by three.

In our case, though, we already have the volume. We need to undo the equation so that we can find the area of the circle base.

In our equation the last thing we do is divide by three. So, we will want to multiply by three to undo this.

4,170*3= 12510

The other step we took was multiply the base by the height, which is 20 centimeters.  To get our base, we will divide by the height instead!

12510/20= 625.5

Therefore, the area of the base of the cone is 625.5 centimeters squared.

Answer:

Answer is either A or B

Step-by-step explanation:

The answer of resulting vector "f(uv)=ue v−sin( vu)+u 3v 2" depends on the specific values of \(e^5, e^8,\) sin(-10), sin(-40), and the fractions involved, so it cannot be determined exactly without those values.

To evaluate the expression f(uv) = u\(e^v\) - sin(vu) + u/(3\(v^2\)), we'll use the given vectors u = <-2, -5> and v = <5, 8>. First, let's calculate the individual components of the expression:

u\(e^v\): Multiply each component of u by \(e^v\). ue^v = <-2\(e^5\), -5\(e^8\)>. sin(vu): Multiply each component of v by the corresponding component of u, and take the sine of the resulting vector. vu = <5*(-2), 8*(-5)> = <-10, -40>. sin(vu) = <sin(-10), sin(-40)>.

u/(32): Divide each component of u by the square of the corresponding component of v, multiplied by 3. \(v^2 = < 5^2, 8^2\)> = <25, 64>. u/(32) = <-2/(325), -5/(364)>.

Finally, we add all the calculated vectors together to obtain the final result: f(uv) = u\(e^v\) - sin(vu) + u/(3\(v^2\)) = <-2e5, -5e8> - <sin(-10), sin(-40)> + <-2/(325), -5/(364)> = <-2e^5 - sin(-10) - 2/(325), -5e^8 - sin(-40) - 5/(364)>.

The resulting vector depends on the specific values of \(e^5, e^8,\) sin(-10), sin(-40), and the fractions involved, so it cannot be determined exactly without those values. However, by substituting the known values, you can obtain the numerical evaluation of the expression f(uv).

On average, Italians spend 7.9 weeks on vacation, while Americans spend 3.9 weeks. Italians have a longer average vacation time than Americans by 4 weeks.

To find the average vacation time for Americans and Italians, we can set up a system of equations. Let's assume that the average vacation time for Americans is represented by 'A' and the average vacation time for Italians is represented by 'I'.

Given that the average time Italians spend on vacation exceeds the average American vacation time by 4 weeks, we can write the equation: I = A + 4.

The combined average vacation time for Americans and Italians is 11.8 weeks, which gives us another equation: A + I = 11.8.

We can substitute the first equation into the second equation to eliminate 'I'. By substituting A + 4 for I in the second equation, we get A + (A + 4) = 11.8.

Simplifying the equation gives us 2A + 4 = 11.8. Subtracting 4 from both sides gives 2A = 7.8. Dividing by 2, we find that A = 3.9.

Therefore, the average vacation time for Americans is 3.9 weeks. Since I = A + 4, the average vacation time for Italians is 7.9 weeks.

In conclusion, Italians spend an average of 7.9 weeks on vacation, exceeding the average American vacation time by 4 weeks. Americans, on the other hand, have an average vacation time of 3.9 weeks.

Roger will need to sleep for 8 days before he has slept the equivalent of one day. This is because 3/8 of one day is 8/24 of a day, which is the same as one day.

To calculate how many days it will take Roger to sleep the equivalent of one day, we can use fractions. First, we need to convert the fractions in the table to fractions with a common denominator. The fractions in the table have denominators of 3, 8, 8 and 6 respectively. The least common multiple of these numbers is 24, so we can convert the fractions to 24ths. We can then add the fractions to calculate how much of a day Roger spends sleeping. 3/8 of one day is 8/24 of a day, and this is the same as one day. Therefore, it will take Roger 8 days to sleep the equivalent of one day.
