Shen the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the other (not both). On Wednesday there were clients who did Plan A and who did Plan B. On Thursday there were clients who did Plan A and who did Plan B. Shen trained his Wednesday clients for a total of hours and his Thursday clients for a total of hours. How long does each of the workout plans last?
Answers
The length of time that it will take for each of the workout sessions would be: Plan A = 1.5 hours, and Plan B = 0.5 hours.
What would be the length of the sessions?The length of the sessions can be obtained by first obtaining drawing a system of equations for the two cases. On Wednesday, we can represent the sessions as follows:
2A + 12B = 9 hours
On Thursday, we would have
5A + 3B = 9 hours
2A + 12B = 9 Eqn 1
5A + 3B = 9 Eqn 2
Multiply equation 2 by -4
2A + 12B = 9
-20A - 12B = -36
2A - 20A = 9 -36
-18A = -27
Divide both sides by -18
A = 1.5 hours
For B, substitute A in the first equation
2(1.5) + 12B = 9
3 + 12B = 9
12B = 9 - 3
12B = 6
Divide both sides by 12
B = 0.5

Suppose that the perimeter of a rectangle is 34 feet, and the length is 7 feet more than the width. Find the width of the rectangle, in feet.
Answers
Answer:
5 feet
Step-by-step explanation:
Let's call the width of the rectangle "w". Then, the length would be "w + 7".
The perimeter of the rectangle is given as 34 feet, so we can set up an equation using the two sides of the rectangle:
2w + 2(w + 7) = 34
Expanding the second term and simplifying the equation, we get:
2w + 2w + 14 = 34
4w + 14 = 34
4w = 20
w = 5
Therefore, the width of the rectangle is 5 feet.

Step-by-step explanation:
Given
\(Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m\)
Though the question has a missing attachment, it can still be answered
Solving (a): The name of the polygon
Since we are given 5 side lengths, we can say that the polygon has 5 sides.
Such polygon is referred to as, a pentagon
Solving (b): The perimeter (in cm)
To do this, we simply add up the side lengths
\(Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m\)
\(Perimeter= 3.65m+ 2.24m+ 2.57m+ 2.24m+ 3.65m\)
\(Perimeter= 14.35m\)
Convert to cm
\(Perimeter= 14.35*100cm\)
\(Perimeter= 1435cm\)

Step-by-step explanation:
xA radioactive isotope is decaying at a rate of 20% every hour. Currently there are 15 grams of the substance.
Questions:
A. Write an equation that will represent the number of grams present after n hours
B. How much will be left after 24 hours (one day)? (Round to the nearest hundredth)
C. After how many hours will there be approximately one gram left?
Answers
B. After 24 hours, approximately 2.49 grams will be left.
C. After approximately 18.13 hours, there will be approximately one gram left.
A. To represent the number of grams present after n hours, we can use the equation:
N(n) = 15 × (1 - 0.2)^n
Where:
N(n) is the number of grams present after n hours,
15 is the initial amount of the substance in grams,
0.2 represents the decay rate of 20% per hour, and
^n represents the exponentiation operation.
B. To find out how much will be left after 24 hours, we can substitute n = 24 into the equation from part A:
N(24) = 15 × (1 - 0.2)^24
Calculating this expression, we find that approximately 2.49 grams will be left after 24 hours.
C. We need to determine the number of hours it takes until there is approximately one gram left. We can set up the equation:
1 = 15 × (1 - 0.2)^n
To solve for n, we can divide both sides of the equation by 15 and then take the logarithm (base 0.8) of both sides:
log(0.8)(1/15) = n
Using a calculator or logarithmic properties, we find that approximately 18.13 hours are required until there is approximately one gram left.
Therefore, the answers are:
B. After 24 hours, approximately 2.49 grams will be left.
C. After approximately 18.13 hours, there will be approximately one gram left.

Verify directly that F is an antiderivative of f.
Answers
F(x) is an antiderivative of f(x) because F'(x) = f(x)
What is an antiderivative?An anti-derivative is the integral of a function
To verify that F is an antiderivative of f where
F(x) = √(3x² - 4) and f(x) = 3x/√(3x² - 4)
This means that F(x) = ∫f(x)
This implies that F'(x) = f(x)
So, we verify as follows
F(x) = √(3x² - 4)
Taking the derivative with respect to x, we have that
dF(x)/dx = d√(3x² - 4)/dx
Let u = 3x² - 4
So, dF(x)/dx = d√u/dx
= d√u/du × du/dx
= 1/(2√u) × du/dx
Now,du/dx = d(3x² - 4)/dx
= 6x
So,
dF(x)/dx = 1/(2√u) × du/dx
= 1/(2√(3x² - 4)) × 6x
= 1/(√(3x² - 4)) × 3x
= 3x/(√(3x² - 4))
= f(x)
So, F(x) is an antiderivative of f(x) because F'(x) = f(x)

What is Integration ?In mathematics, an integral lends numerical values to functions to represent concepts like volume, area, and displacement that result from combining infinitesimally small amounts of data. Integration is the action of locating integrals.
According to the given information
We can find the length of the arc by
L = \(\int\limits^a_b {\sqrt{\frac{dx}{dt} ^{2}+\frac{dy}{dt} ^{2} } } \, dt\)
Find the derivative of x w.r.t to t
dx/dt = \(3t^{\frac{1}{2} }\)
Find the derivative of y w.r.t to t
dy/dt = 2
Putting the values in above equation
We get
L = \(\int\limits^a_b {\sqrt{\frac{dx}{dt} ^{2}+\frac{dy}{dt} ^{2} } } \, dt\)
L= \(\int\limits^2_0 {\sqrt{9t+4} } \, dt\)
L = \(\frac{2}{27}(9t+4)^{\frac{3}{2} }\)

Justin has 10 nickels and 5 dimes.
Step-by-step explanation:
Given that Justin has x nickels and y dimes, and he has a minimum of 15 coins worth at most $ 1 combined, to determine one possible solution the following calculation must be performed:
Nickel = 0.05
Dime = 0.10
15 x 0.05 + 0 x 0.1 = 0.75
14 x 0.05 + 1 x 0.1 = 0.80
13 x 0.05 + 2 x 0.1 = 0.85
12 x 0.05 + 3 x 0.1 = 0.90
11 x 0.05 + 4 x 0.1 = 0.95
10 x 0.05 + 5 x 0.1 = 1
So, Justin has 10 nickels and 5 dimes.

\(\qquad\displaystyle \tt \dashrightarrow \: x = 20\)
Value of x = 20°
Hey! there . Thanks for your question :)
Answer:
20° is the correct answer.Step-by-step explanation:
In this question we are given with two interior angles of the triangle that are 40° and 70° , also we are given an exterior angle that is (5x + 10)°. And we are asked to find the value of angle x.
Solution :-
For finding the value of angle x , we have to use exterior angle property of triangle which states that sum of opposite interior angles of triangle is equal to the given exterior angle. So :
Step 1: Making equation :
\( \longmapsto \: \sf{40 {}^{°} + 70 {}^{°} = (5x + 10) {}^{°} }\)
Solving :
\( \longmapsto \: \sf{110 {}{°} = (5x) {}^{°} +10 {}^{°} }\)
Step 2: Subtracting 10 on both sides :
\( \longmapsto \sf{ 110 {}^{°} - 10 {}^{°} = 5x + \cancel{10 {}^{°}} - \cancel{10 {}^{°} } }\)
We get ,
\( \longmapsto \sf{(5x ){}^{°} = 100 {}^{°} }\)
Step 3: Dividing both sides by 5 :
\( \longmapsto \dfrac{ \cancel{5}x {}^{°} }{ \cancel{5}} = \dfrac{ \: \: \: \: \cancel{ 100} {°}^{} }{ \cancel{5} }\)
On cancelling , we get :
\( \longmapsto \underline{\boxed{\red{\sf{ \bold{ x = 20 {}^{°} }}}}} \: \: \bigstar\)
Therefore , value of x is '20°'Verification :-
For verifying sum of both the interior angles is equal to given exterior angles. As we get the value of x as 20 we need to substitute it's value in place x and then L.H.S must be equal to R.H.S :
40° + 70° = 5(20°) + 10°110° = 100° + 10°110° = 110°L.H.S = R.H.STherefore , our answer is correct .

When x = 12, y =
Answers
y = a(x - 2)^2 + 5
where a is a coefficient that determines the shape and direction of the parabola.
We can find the value of a by substituting the coordinates of the given point (22, 365) into the equation:
365 = a(22 - 2)^2 + 5
Then, we can solve for a by rearranging the terms and solving for a:
360 = a(20^2)
a = 360 / (20^2)
a = 0.225
Now that we have found the value of a, we can substitute it back into the equation to get the final equation of the parabola:
y = 0.225(x - 2)^2 + 5
To find the value of y when x = 12, we can substitute 12 for x in the equation:
y = 0.225(12 - 2)^2 + 5
y = 0.225(10^2) + 5
y = 2.25 + 5
y = 7.25
Therefore, the value of y when x = 12 is 7.25.

Answers
Answer:
I am not sure if you're accustomed to using a z-score and table of probabilities or technology, so I will answer using both!
a) Since you're choosing one person from the population, you will use the mean and standard deviation from the population. z= (210.9-197.5)/8.6 = 1.56 Using a table of normal probabilities,
P(x>210.9)= 1-P(z<1.56)= 1- 0.9406=0.0594
Using technology: normalcdf(210.9, 1E99, 197.5, 8.6)=0.0596
b) Since you're calculating the population for a sample to occur, you need to get a mean of the sampling distribution and standard deviation of the sampling distribution.
Meanpop=Meansampling dist.=197.5
St. Devsampling dist.= Stdpopulation/√n = 8.6/√15 = 2.22
Using technology, P(X>196.20)= normalcdf( 196.20, 1E99, 197.5, 2.22) = 0.7209
c) You only have to worry about the sample size in a sampling distribution if you either do not know the shape of the distribution of the population or if the distribution of the population is not normally distributed. Since this population is normally distributed (as stated in the given information), then your sample size does not have to be greater than 30.

P(A/B) = P(A and B)/P(B)
Substitute the known values in the above equation, so, we have the following representation
0.2/P(B) = 0.8
