Answer:
[tex]2\sqrt{5}[/tex]
Step-by-step explanation:
You can use the Pythagorean Theorem, which is [tex]a^{2}+ b^{2}= c^{2}[/tex]. So the the distance from -9 to -5 is 4 and the distance from 8 to 6 is 2.
So [tex]4^{2} +2^{2} =c^{2}[/tex]. Which equals [tex]20=c^{2}[/tex].
Then you square root [tex]c^{2}[/tex] to make it c, then you do that to the other side. So you have [tex]\sqrt{20}=c[/tex].
Which equals [tex]2\sqrt{5}[/tex].
Or you can use the Distance Formula, which is [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex].
The [tex]x_{1}[/tex] is -5 and the [tex]x_{2}[/tex] is -9. The [tex]y_{1}[/tex] is 6 and the [tex]y_{2}[/tex] is 8. When you plug that in you get [tex]\sqrt{(-9--5)^{2} +(8-6))^{2} }[/tex]. When you simplify that you get [tex]\sqrt{20}[/tex].
Which equals [tex]2\sqrt{5}[/tex].
What is the solution to the equation below? Round your answer to two
decimal places.
log₂ x = 2.5
The solution of the logarithmic equation is approximately 5.66 .
The logarithm is a simpler way to write a exponential equation.
The exponential equation nˣ = b is written as logₙ b = x ( read as logarithm of b to the base of n is equal to x).
The various properties of logarithm are:
log x+ log y= log x ylog x - log y= log(x/y)log xⁿ=n log xThe given equation is :
log₂ x = 2.5
This equation is of the form logₐ b=n
We know that from the properties of logarithm logₐ b=n is equivalent to aⁿ=b.
So the given equation can be written as
[tex]x=2^{2.5}[/tex]
Solving we get
x=5.6568....
or, x≈5.66
Therefore the logarithm equation has a solution for x where the value of x is approximately 5.66.

How to calculate the value?The information illustrates that the project manager is calculating work forecasts and he manager's team completed 4/5 of a job in 16 days.
Therefore, the amount that was done each day will be:
= 4/5 ÷ 16
= 4/5 × 1/16

last year 30 people went on a family trip to universal this is 5 times as many people that went the year before. how many people went the uear before?
Answer:
6 people
Step-by-step explanation:
To figure this out, let's set up an equation.
We know 30 people went last year to Universal, and that this is 5 times as many people as who went the year before
So to figure out how many went the year before, we divide 30 by 5
30/5 = 6
So 6 people went to Universal the year before.

Given the following composite figure, d = 7.5 cm and w = 15.1 cm.
What is the area of the figure?
Answer:
157.41
Step-by-step explanation:
It can be identified that, given the figure, there is a rectangle and 2 semicircles.
Let's find the area of the rectangle first: A=L*w
Plugging in the given values => A=7.5*15.1 which equals 113.25.
Now the area for the semicircles: 1/2(3.14*r^2)
First, we need to find the radius. To find the radius, you just have to divide the diameter by 2. So, 7.5/2=3.75.
We can plug square the radius which is 3.75 and plug it into the formula: 1/2(3.14*3.75^2)=>22.078125.
22.078125 is the area of only one semicircle so we need to multiply it by 2 because we have two semicircles. So, we get 44.15625.
Finally, we can add them all up to find the total area of the figure: 113.25+44.15625=157.40625.
Rounding to the nearest hundredth=>157.41

According to data from the CDC, about 37.1% of adults (individuals 18 years of age or older) in the United States and 57.9% of children (individuals between 6 months and 17 years of age) in the United States received a flu vaccine during the 2017-2018 flu season.
a) Consider a random sample of 50 adults.
i. Calculate the probability that exactly 20 adults received a flu vaccine.
Using the binomial distribution, there is a 0.1094 = 10.94% probability that exactly 20 adults received a flu vaccine.
For each adult, there are only two possible outcomes, either they received the vaccine or they did not. The probability of an adult receiving the vaccine is independent of any other adult, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.For this problem, we have that:
There is a random sample of 50 adults, hence n = 50.37.1% of adults received the flu vaccine, hence p = 0.371.The probability that exactly 20 adults received a flu vaccine is P(X = 20), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 20) = C_{50,20}.(0.371)^{20}.(0.629)^{30} = 0.1094[/tex]
0.1094 = 10.94% probability that exactly 20 adults received a flu vaccine.

6X0.39 x 10^9
Put in scientific notation and explain how it works.
Answer:
3.9 x [tex]10^{8}[/tex]
Step-by-step explanation:
0.39 is not in scientific notation. For a number to be in scientific notation the first factor has to be 1 or greater, but less then 10. 0.39 is less than one.
First we must write 0.39 in scientific notation. We need to move the decimal so that the number is greater than 1, but less than ten. If we move the decimal one place to the right, we get 3.9. The standard number is smaller than 3.9. How much smaller? [tex]10^{-1}[/tex] smaller.
0.39 in scientific notation would be 3.9 x [tex]10^{-1}[/tex]. We cannot forget the [tex]10^{9}[/tex], so our number looks like this now:
3.9 x [tex]10^{-1}[/tex] x [tex]10^{9}[/tex] The product of powers principle tells us that if we have powers with the same bases, we can add the exponents.
3.9 x [tex]10^{-1+9}[/tex]

following a recipe to make punch for a party. The rect cakks for 2 cups of juice for every 3 cups o
f seltzer. If I have 12 cups of seltzer, how many cups of juice do I need?
You need 8 cups of juice for 12 cups of seltzer.
Representing the first statement in ratio form. So, number of cups of juice: number of cups of seltzer = 2:3. Similarly, for second statement, let the number of cups of juice be x.
Forming the equation with ratio on both sides -
2:3 = x:12
Writing the mentioned equation as fraction to solve for the value of x
x = (2 × 12)/3
Performing multiplication in numerator to find the value of x
x = 24/3
Dividing the numerator and denominator by 3 to find the value of x
x = 8
Therefore, 8 cups of juice is needed for 12 cups of seltzer.

Beth is making a beanbag seat in the shape of a cube. Each side of the seat is 2 feet long. Beth needs to find the volume of the seat so that she can buy the correct amount of bean. Beans are sold in bags that hold 2 cubic feet of beans. How many bags should Beth buy?
With the help of the volume of cube it is concluded that Beth should buy 4 bags of beans.
What Is Volume of Cube?The volume of a cube is the total three-dimensional space that it occupy. A cube's volume is expressed as cubic units. The SI unit of volume is the cubic meter [tex](m^3)[/tex], which is the volume occupied by a cube with each side measuring 1 m.
The first thing to do in this case is to find the volume of the cube, which will be given by:
