Answer:
y=0.5+sqrt(17)
Step-by-step explanation:
Let y=sqrt{4+sqrt{4+...+sqrt(4)}
y=sqrt(4+y). (Since it's an infinite series)
y^2=4+y, y=0.5-sqrt(17) or 0.5+sqrt(17). We will omit the negative since root values are positive.
Two friends went to get ice cream sundaes. They each chose a flavor of ice cream from a list of vanilla and chocolate and toppings from a list of hot fudge, strawberries, sprinkles, peanuts, and whipped cream. Use the sets below describing their choices and find B'.
Let A = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}
Let B = {vanilla, hot fudge, sprinkles, whipped cream}
Let C = {chocolate, hot fudge, peanuts, whipped cream}
The complement of set B denoted by B' is are {chocolate, strawberries, peanuts}
What is a Venn Diagram?A Venn diagram is a diagrammatic illustration showing the various components of a set in a diagram. The venn diagram for each set is usually enclosed in a circle and those circle(s) are inscribed in a rectangle known as the Universal Set.
A complement of a set is a set that is not from the Universal Set.
Let's assume that we use the initials of each word to represent them in a Venn diagram. Then;
Universal Set (U) = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream} Let A = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}Let B = {vanilla, hot fudge, sprinkles, whipped cream}Let C = {chocolate, hot fudge, peanuts, whipped cream}The complement of Set B denoted at B' = {chocolate, strawberries, peanuts}

The Science Club arranged a trip to Smithsonian. Only 2/3 of the members were able to attend, which left one seat empty on the 25-passenger bus. How many members does the Science Club have?
Answer:
36 members
Step-by-step explanation:
Let x = the number of science club members
There are 24 people on the bus (1 seat empty on the 25 seat bus)
2/3 of the club attended and that equals 24 people on the bus
2/3x = 24
Multiply each side by 3/2
3/2 * 2/3x = 24 * 3/2
x = 36
IBM issued 30-year bonds with an annual simple interest rate of 6.22%. Find the semiannual interest payment on a$5,000 bond.
9514 1404 393
Answer:
$155.50
Step-by-step explanation:
The interest is given by the formula ...
I = Prt
where P is the principal earning interest at annual rate r for t years. The interest period here is 1/2 year.
I = $5000×0.0622×1/2 = $155.50
The semiannual interest payment is $155.50 on this bond.
What is 7/9 divided by1/3
Answer:
2.33333333333
Step-by-step explanation:
7/9 divided by 1/3 = 2.33333333333
Answer:
2 1/3
Step-by-step explanation:
When dividing fractions, you need to convert the problem to multiplication by taking the reciprocal of the second fraction. 7/9 divided by 1/3 therefore becomes 7/9 * 3. 7 * 3 = 21 and this value is over 9, so you currently have 21/9, but wait: we can simplify this.
21/9 can be simplified to 7/3, which can be simplified further to 2 1/3.

The feet of the average adult woman are 24.6 cm long, and foot lengths are normally distributed. If 16% of adult women have feet that are shorter than 22 cm, approximately what percent of adult women have feet longer than 27.2 cm?
Answer:
Approximately 16% of adult women have feet longer than 27.2 cm.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The feet of the average adult woman are 24.6 cm long
This means that [tex]\mu = 24.6[/tex]
16% of adult women have feet that are shorter than 22 cm
This means that when [tex]X = 22[/tex], Z has a p-value of 0.16, so when [tex]X = 22, Z = -1[/tex]. We use this to find [tex]\sigma[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1 = \frac{22 - 24.6}{\sigma}[/tex]
[tex]-\sigma = -2.6[/tex]
[tex]\sigma = 2.6[/tex]
Approximately what percent of adult women have feet longer than 27.2 cm?
The proportion is 1 subtracted by the p-value of Z when X = 27.2. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{27.2 - 24.6}{2.6}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a p-value of 0.84.
1 - 0.84 = 0.16
0.16*100% = 16%.
Approximately 16% of adult women have feet longer than 27.2 cm.

On her summer abroad in France, Jane bought a pair of shoes for 54.82 euros. The store owner only had francs to give her as change. She gave him 55 euros. How much did he give her back in francs
Answer:
0.19
Step-by-step explanation:
Jane bought a shoe for 54.82 euros
She gave the store owner 55 euros
= 55-54.82
= 0.18 euros to franc
= 0.18× 1.08222
= 0.19 franc
A ball is dropped from 248 feet above
the ground level and after the second
bounce it rises to the height of 62 feet.
If the height to which the ball rises
after each bounce is always the same
fraction of the height reached on its
previous bounce, what is this
fraction?
Let us say
The Height from which the ball was first dropped as H0 = 248 feet
The Height reached by the ball after second bounce is H1
The Height reached by the ball after second bounce is H2 = 62 feet
Given , Height the ball reaches after bounce is a fraction of the height the ball reached in the previous bounce
The Height reached by the ball after second bounce = H2 = X of H1
==> 62 = X * H1 ...................Equation 1
The Height reached by the ball after first bounce = H1 = X of H0
==> H1 = X * 248 ...................Equation 2
Substituting value of H1 from Equation 2 to Equation 1
62 = X * H1 = X * X * 248
X^2 = 62/248 = 31/124 = 1/4
X = 1/2
Answer is A. 1/2

If the cost, C, for manufacturing x units of a certain product is given by c=x^2-5x+65, find the number of units manufactured at a cost of 13,865.
9514 1404 393
Answer:
120
Step-by-step explanation:
I find it pretty easy to obtain the solution by graphing ...
c(x) -13865 = 0
The positive value of x that makes this so is x = 120.
120 units will have a cost of 13,865 to manufacture.
__
If you like to solve this algebraically, you can probably do it most easily by completing the square.
x^2 -5x = -65 +13865
x^2 -5x +6.25 = 13806.25 . . . . . add the square of (-5/2)
(x -2.5)² = 13806.25
x -2.5 = √13806.25 = 117.5 . . . . only the positive square root is interesting
x = 117.5 +2.5 = 120

Corinne solved the equation below:
5x = 95
5x − 5 = 95 − 5
x = 90
Is Corinne's solution correct? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
Answer:
The solution is incorrect
Step-by-step explanation:
5x = 95
We need to do the opposite
We are multiplying x by 5 so we need to divide by 5
5x/5 = 95/5
x = 19
Corinne's solution is incorrect.
The mistake occurred when she subtracted 5 from both sides of the equation.
We have,
To solve the equation correctly, we need to isolate the variable x. Here are the correct steps:
Starting with the equation:
5x = 95
To isolate x, we divide both sides of the equation by 5:
(5x) / 5 = 95 / 5
x = 19
Thus,
The correct solution to the equation is x = 19.

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 mm
9514 1404 393
Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
Additional comment
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
