C.66%,62%,58%
D67%,67%,67%
E.63%,65%,67%
F.67%,72%,77%
Final answer:
The correct sets of values for the fourth, fifth, and sixth visits' exercise intensity, according to the described F.I.T.T. pattern of increase after consistent intensity, would be options B (66%, 69%, 72%) and E (63%, 65%, 67%).
Explanation:
The student's question regarding the recommended exercise intensity for the aerobic program is a matter related to health and physical education. Specifically, it involves understanding how to apply the F.I.T.T. principle to plan an aerobic workout regimen. The program described outlines a pattern of consistent intensity, followed by a gradual increase and then a decrease in intensity. When looking for the set of values that could represent the intensity of exercises during the fourth, fifth, and sixth visits, we should look for a pattern that indicates an increase in intensity from the prior three consistent visits.
Given the following options, the correct pattern would be one that shows an increase over three visits:
B. 66%, 69%, 72% - This shows a consistent increase in intensity.
E. 63%, 65%, 67% - This also shows a consistent increase in intensity.
Options A, C, D, and F do not fit the pattern of increasing and then decreasing as described in the student's question. Therefore, the correct set of values for the intensity of exercises on the fourth, fifth, and sixth visits are B and E.
Determine if direct variation x-2y=0
Answer:
x-2y=0 is a direct variation
Step-by-step explanation:
Direct variation is of the form
y= kx
Can we get the equation in that form
x-2y =0
Add 2y to each side
x-2y+2y =0_2y
x=2y
Divide each side by 2
x/2 = 2y/2
1/2x =y
Flip the sides
y = 1/2x
This is of the form y= kx where k = 1/2
x-2y=0 is a direct variation

Answer:
[tex]x = 4.45 \\ y=6[/tex]
Step-by-step explanation:
For part a, we'll be needing to find the vertex.
Convert [tex]y=-x^2+4x+2[/tex] into vertex form by factoring and completing the square.
We'll get...
[tex]y=-(x-2)^2+6[/tex]
So the vertex is [tex](2,6)[/tex]
And therefore, the maximum height will be 6.
Now we can find the zeros to find how far it'll be.
Use the quadratic formula.
[tex]x=\frac{-b±\sqrt{b^2-4ac}}{2a}[/tex]
[tex]a=-1 \\ b=4 \\ c = 2[/tex]
Plug them in.
[tex]x=\frac{-4±\sqrt{(4^2)-4(-1)(2)} }{2(-1)}[/tex]
[tex]x=\frac{-4±\sqrt{16--8}}{-2} \\ \\ x=\frac{-4±\sqrt{24}}{-2} \\ \\ x = 4.45, -0.45[/tex]

Find the unknown side length, x.
√65 = x; using the Pythagorean Theorem, 25 [hypotenuse₁] - 9 [short leg₁] = 16 [long leg₁]. Take the square root of 16 to get 4 [reflexive line where the two triangles meet]. Then, you deal with the larger triangle. You have 16 [short leg₂] + 49 [long leg₂] = 65 [hypotenuse₂]. Finally, take the square root of 65, so long it stays √65. There is no perfect square to find that will simplify that 65 inside that radical.
Answer:
B. √65Step-by-step explanation:
Use the Pythagorean theorem for both triangles.
Let y be the common side of the triangles. Therefore:
y² + 3² = 5²
y² + 9 = 25 subtract 9 from both sides
y² = 16
x² = 7² + y²
x² = 49 + 16
x² = 65 ⇒ x = √65
How many triangles can be drawn with one 90° angle ,a 70° angle, and an included side measuring 3 inches?explain
Answer:
1
Step-by-step explanation:
once we know 2 of the angles we can find a third. once we have all 3 angles we only need one side length to tell us how big it is.
Bonus question: How many triangles can be drawn with one 3 inch side ,a 4 inch side, and a 20ºangle?
Only one triangle is formed with an angle 90° , angle 70° and included side with 3 inches.
What is a triangle?
A triangle is a three sided polygon, which has three vertices.
Given that;
Measure of two angles are angle 90° and angle 70°.
Length of side = 3 inches.
Now, Measure of two angles are angle 90° and angle 70°.
Since, Sum of all angles of an triangle are 180°.
Let third angle = x
So, 90° + 70° + x = 180°
160 + x = 180
x = 20°
Thus, We can formed only one triangle.

if f(x)=x/2-3 and g(x)=3x^2+x-6, find (f+g)(x)
The answer is:
[tex]f(x)+g(x)=3x^{2} +\frac{3x}{2}-9[/tex]
Why?We are working with function addition, to add or subtract two o more functions, we need to follow the following form:
[tex](f+g)=f(x)+g(x)[/tex]
To simplify the expression, we need to work with the like terms, like terms are the terms that share the same variable and the same coefficient, for example:
[tex]x+3x+x^{2}=x^{2} +4x[/tex]
We were able to add only the first two terms since the third term does not share the exponent with the other two.
We are given the functions:
[tex]f(x)=\frac{x}{2}-3\\\\g(x)=3x^{2}+x-6[/tex]
So, solving, we have:
[tex]f(x)+g(x)=(\frac{x}{2} -3)+(3x^{2} +x-6)\\\\f(x)+g(x)=3x^{2}+\frac{x}{2}+x-3-6\\\\f(x)+g(x)=3x^{2}+\frac{x+2x}{2}-9\\\\f(x)+g(x)=3x^{2} +\frac{3x}{2}-9[/tex]
Hence, the answer is:
[tex]f(x)+g(x)=3x^{2} +\frac{3x}{2}-9[/tex]
Have a nice day!
To find (f+g)(x), we need to add the two functions f(x) and g(x). Let's do this step by step:
Given functions:
f(x) = x/2 - 3
g(x) = 3x^2 + x - 6
(f+g)(x) means the sum of f(x) and g(x), so we add the two functions together:
(f+g)(x) = f(x) + g(x)
= (x/2 - 3) + (3x^2 + x - 6)
Now, we combine like terms:
(f+g)(x) = 3x^2 + x/2 + x - 3 - 6
There is a common term x/2 and x, which we can combine by finding a common denominator. The common denominator is 2, so we convert x to 2x/2:
(f+g)(x) = 3x^2 + 2x/2 + x/2 - 3 - 6
= 3x^2 + (2x + x)/2 - 3 - 6
= 3x^2 + 3x/2 - 3 - 6
Now we add or subtract the constants:
(f+g)(x) = 3x^2 + 3x/2 - 9
So, the function (f+g)(x) is equal to:
(f+g)(x) = 3x^2 + 3x/2 - 9
And that is the final expression for the sum of f(x) and g(x).

Answer:
The mother's ironing is the main symbol of the story because it reflects on her hopes for Emily. As the mother irons she discusses Emily's life. Through her narration, readers can understand that the mother wanted a smooth life for Emily. But struggles like poverty, unexpected illness, and other negative experiences prevented a normal life for Emily. The iron indicates that the mother wanted to fix Emily. Her sentiments also can be interpreted as regrets that the mother could not help Emily overcome life trials. The ironing can therefore be seen by the readers like the heaviness of a mother's duties towards a child. The continuous action of ironing shows the mother's efforts to address Emily's problems in doing daily tasks. The mother cannot help but reflect upon the reasons Emily developed into a special child. Most importantly, the iron represents that the mother still believes Emily can become a confident person. With the mother's support, Emily may have hope.

Final answer:
The probability of drawing a red marble and then a blue marble from a bag containing a mix of marbles is 5/48, calculated by multiplying the probabilities of each individual event occurring in sequence.
Explanation:
The question asks for the probability of drawing a red and then a blue marble from a bag containing 5 red, 6 white, and 5 blue marbles. We begin by calculating the probability of drawing a red marble, which is 5/16 (since there are 5 red marbles out of a total of 16). After drawing a red marble, we do not replace it, so there are now 15 marbles left. The probability of drawing a blue marble next is 5/15 or 1/3, since there are 5 blue marbles left.
To find the combined probability of two independent events, we multiply their individual probabilities. Therefore, the probability of drawing a red then a blue marble without replacement is 5/16 * 1/3, which simplifies to 5/48. So, P(red and blue) is 5/48.
What is the wavelength for radio waves with frequency 3x10^9
The wavelength of radio waves with a frequency of 3x10^9 Hz can be calculated using the equation c = λf. By substituting the given values and solving for λ, we find that the wavelength is approximately 10 cm.
Explanation:To find the wavelength of radio waves with frequency 3x10^9, first, we need to understand that wave speed, wavelength, and frequency are interconnected. This relation can be written as c = λf, where 'c' is the speed of light, 'λ' is the wavelength and 'f' is the frequency. Given the speed of light, c, is approximately 3.00x10^8 m/s, and the frequency, f, is 3x10^9 Hz, we can substitute these values into the equation and solve for λ (wavelength). This will give us λ = c / f = 3.00x10^8 m/s / 3x10^9 Hz = 0.1 m or 10 cm.
Therefore, the wavelength of the radio waves with a frequency of 3x10^9 Hz is 10 cm.

To find the wavelength of radio waves with a frequency of 3x10⁹ Hz, use the equation c = fλ, where c is the speed of light (3.00x10^8 m/s). The wavelength is calculated to be 0.1 meters.
Explanation:The question is asking us to calculate the wavelength of radio waves with a given frequency. The formula that connects the speed of light (c), frequency (f), and wavelength (λ) is c = fλ, where c is the speed of light in a vacuum, which is approximately 3.00 × 108 m/s.
To find the wavelength for radio waves with a frequency of 3 × 10⁹ Hz, we can rearrange the formula to λ = c/f. Thus:
λ = (3.00 × 10⁸ m/s) / (3 × 10⁹ Hz)
= 0.1 meters

What is the probability of an event?The probability of an event is the fractional value determining how likely is that event to take place. If the event is denoted by A, the number of outcomes favoring the event A is n and the total number of outcomes is S, then the probability of the event A is given as:
P(A) = n/S.
What are the odds of a given event?When a given event suppose A, has a Probability of occurring = P(A) and Probability of not happening = 1 - P(A).
When we calculate the odds in favor of event A, the value is given by the ratio, P(A):(1 - P(A)).
When we calculate the odds against the event A, the value is given by the ratio, (1 - P(A)):P(A).
How do we solve the given question?We are informed that a bag contains eleven red marbles, seven blue marbles, nine green marbles, and thirteen yellow marbles.
Let the event of selecting a red marble from the bag be R.
Number of outcomes favoring R = 11 (number of red marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event R is P(R) = 11/40
1 - P(R) = 1 - 11/40 = 29/40
Let the event of selecting a blue marble from the bag be B.
Number of outcomes favoring B = 7 (number of blue marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event B is P(B) = 7/40
1 - P(B) = 1 - 7/40 = 33/40
Let the event of selecting a green marble from the bag be G.
Number of outcomes favoring G = 9 (number of green marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event G is P(G) = 9/40
1 - P(G) = 1 - 9/40 = 31/40
Let the event of selecting a yellow marble from the bag be Y.
Number of outcomes favoring Y = 13 (number of yellow marbles)
Total number of outcomes = 40 (number of marbles in the bag)
∴ The probability of the event Y is P(Y) = 13/40
1 - P(y) = 1 - 13/40 = 27/40
Now, we analyze all the options, to check for the ones which are not true.
a. The theoretical probability of selecting a red marble from the bag is 27.5%.
The probability of selecting a red marble P(R) = 11/40 =11/40 * 100% = 27.5%, which is the same we are looking for.
∴ The statement is true.
b. The odds of selecting a yellow marble from the bag are 13 to 27.
The odds of selecting a yellow marble (odds in favor) = P(Y)/(1 - P(Y)) = 13/27 or 13 to 27, which is the value we are looking for.
∴ The statement is true.
c. The theoretical probability of selecting a blue or green marble from the bag is 2/3.
The probability of selecting a blue or green marble from the bag = P(B) + P(G) = 7/40 + 9/40 = 16/40 = 2/5, which is not the value we are looking for.
∴ The statement is not true.
d. The odds of selecting a red or blue marble are 9/11.
The probability of selecting a red or blue marble from the bag
P(R+B) = P(R) + P(B) = 11/40 + 7/40 = 18/40 = 9/20.
1 - P(R+B) = 1 - 9/20 = 11/20
∴ Odds of selecting a red or blue marble (odds in favor)
= P(R+B)/(1 - P(R+B)) = (9/20)/(11/20) = 9/11, which is the value we are looking for.
∴ The statement is true.
So, among the given statements, c. The theoretical probability of selecting a blue or green marble from the bag is 2/3. which is not true.

Please help me with geometry.
Answer:
m<6 = 50
Step-by-step explanation: Just trust me
Answer:
50 degrees
Step-by-step explanation:
When two parallel lines are cut by a transversal, same side interior angles are supplementary.
In the figure, parallel lines AB and CD are cut by the tranversal shown forming 8 angles. Angles 3 and 6 are same side interior angles, so they are supplementary. That means that their measures have a sum of 180 degrees.
m<3 + m<6 = 180
130 + m<6 = 180
m<6 = 180 - 130
m<6 = 50

If you dropped a vertical line from P to the x-axis to make a right triangle, what is the length of the hypotenuse, r?
Answer:
13
Step-by-step explanation:
First drop the line.
How many units is it from Point r to the x axis?
12.
How many units is it from Point r to the y axis?
5.
Now we can use the Pythagorean Theorem.
[tex]12^2+5^2=c^2 \\ \\ 144+25=c^2 \\ \\ c^2=169 \\ \\ c=13[/tex]
The calculated length of the hypotenuse r has a value of 13 units
How to determine the length of the hypotenuseFrom the question, we have the following parameters that can be used in our computation:
The point P
Where, we have
P = (-5, 12)
This means that
(x, y) = (-5, 12)
The length of the hypotenuse r is calculated as
r = √[x² + y²]
Substitute the known values into the equation
r = √[(-5)² + 12²]
r = √169
When evaluated, we have
r = 13
Hence, the length of the hypotenuse is 13 units

AB and BC form a right angle at point B. if A= (-3, -1) and B = (4, 4), what is the equation of BC
Answer:
With fractions: [tex]y=-\frac{7}{5} x+\frac{48}{5}[/tex]
With decimals: [tex]y=-1.4x+9.6[/tex]
Step-by-step explanation:
First we are finding the slope of line AB using the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where
[tex]m[/tex] is the slope
[tex](x_1,y_1)[/tex] are the coordinates of the first point
[tex](x_2,y_2)[/tex] are the coordinates of the second point
The first point is A= (-3, -1) and the second one is B = (4, 4), so [tex]x_1=-3[/tex], [tex]y_1=-1[/tex], [tex]x_2=4[/tex] and [tex]y_2=4[/tex].
Replacing values
[tex]m=\frac{4-(-1)}{4-(-3)}[/tex]
[tex]m=\frac{4+1}{4+3}[/tex]
[tex]m=\frac{5}{7}[/tex]
Now, since AB and BC form a right angle, BC is perpendicular to AB. The slope of a perpendicular line is the negative reciprocal of the other line; in other words, the slope of BC is the negative reciprocal of the slope of AB. To find the negative reciprocal of the slope of AB we just need to multiply its slope by -1 and invert the fraction:
[tex]m_{AB}=\frac{5}{7}[/tex]
[tex]m_{BC}=-\frac{7}{5}[/tex]
Finally, to complete the equation of BC, we are using the point-slope formula:
[tex]y-y_1=m(x-x_1)[/tex]
where
[tex]m[/tex] is the slope
[tex](x_1,y_1)[/tex] are the coordinates of the point
We know that [tex]m_{BC}=-\frac{7}{5}[/tex], so [tex]m=-\frac{7}{5}[/tex]. Since the line passes throughout point B = (4, 4), [tex]x_1=4[/tex] and [tex]y_1=4[/tex].
Replacing values
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-4=-\frac{7}{5} (x-4)[/tex]
[tex]y-4=-\frac{7}{5} x+\frac{28}{5}[/tex]
[tex]y=-\frac{7}{5} x+\frac{28}{5}+4[/tex]
[tex]y=-\frac{7}{5} x+\frac{48}{5}[/tex]
[tex]y=-1.4x+9.6[/tex]
