If 5 and 12 are the two smallest values in a Pythagorean triple, what is the largest value, c, in the triple?
=============================================
Work Shown:
a^2 + b^2 = c^2
c = sqrt( a^2 + b^2 )
c = sqrt( 5^2 + 12^2 )
c = sqrt( 25 + 144 )
c = sqrt( 169 )
c = 13

The perimeter is 5+12+13 = 30 units and the area is base*height/2 = 5*12/2 = 60/2 = 30 square units. In this triangle type, the area and perimeter are the same value (different units though of course). This concept and particular triangle is discussed in the video titled "Superhero triangles" from Numberphile (timestamp around 1:23 of the video).
The graph of a function is shown.
What is the maximum value of the function?
Answer:
3
Step-by-step explanation:
The maximum value of the function is 3.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The maximum value of a function is the highest output value that the function can attain over its entire domain.
Now,
From the graph,
The y-values are called the output.
The y-value is from -∞ to 3 and 3 to -∞.
This means,
The range of the function is -∞ to 3 and 3 to -∞.
Now,
The highest output is 3.
Thus,
The maximum value of the function is 3.

teresa repartee un chocolate entre sus hermanos. ella le dio 1/3 a miguel y 1/4 a diego. que parte de chocolate repartido teresa?
Answer:
5/12
Step-by-step explanation:
Deje que el chocolate total se represente como 1
La cantidad de tarta de chocolate que le llega a Teresa es:
1 - (1/3 + 1/4)
Mínimo común denominador = 12
1 - (4 + 3/12)
1 - 7/12
= 5/12
La cantidad o fracción de la tarta de chocolate que le queda a Teresa es 5/12
which of these relations are functions
Answer:
The fourth and fifth options.
Step-by-step explanation:
Now, there are two key points to this question that are essential - first, in a relation that is a function, for every input, there is only one single output. For instance, in the first option, we can see that when x=2, y=11 and 15. Hence, it is ruled out. The same goes for the third option; of the coordinates, it is clear that certain values overlap, and in the final option, when x= -4, y= -2 and -5.
In the fifth option, however, the input (x) leads to only one output value (y) each. Therefore, it is a function.
Secondly, the vertical line test is a visual way to determine if a curve is a graph of a function or not. The best way to do this is to either visualise a vertical straight line, or get a ruler of some sort, and drag it across the graph. If at any time, the vertical line touches more than one point, it is not a function.
If the coordinates in the second option are joined, we can see that two of them have the same x-coordinate - thus, the line would touch two points, and it is not a function.
In the fourth option, on the other hand, the vertical line only touches one point throughout the entire graph - therefore, it is a function.

Finding the next terms of an arithmetic sequence with integers The first three terms of an arithmetic sequence are as follows. 10, 13, 16 Find the next two terms of this sequence. help
Answer:
19, 22
Step-by-step explanation:
Because this is an arithmetic sequence, we know there is a constant difference between each value.
To find that difference, lets take two consecutive values, (10 and 13) and subtract them.
13 - 10 = 3
We see the same number if we used
16 - 13 = 3
So the pattern here, is each number + 3.
16 + 3 = 19
19 + 3 = 22
22 + 3 = 25

You need to design a rectangle with a perimeter of 11 cm. The length must be 2.8 cm. What is the width of the rectangle? (You might want to draw a picture.)
a) Let w = the width of the rectangle. Write the equation you would use to solve this problem.
Step-by-step explanation:
p = 2×( l+w)
p = 2×l + 2×w
=> 2×w = p - 2×l
w = (p - 2×l) / 2
w = (11 - (2×2.8))/2
= (11- 5.6)/2
= 5.4 /2
= 2.7 cm

A reporter announces that there is an 80% chance of a thunderstorm tomorrow, and if the thunderstorm materializes, there is a 14% chance that it will produce a tornado.What is the probability that there will be a tornado tomorrow? What is the probability that there is a storm, but does not produce a tornado?
Answer & Step-by-step explanation:
We will only get a tornado if there is already a thunderstorm materializing
0.80 * 0.14 = 0.112
Probability of a tornado = 11.2%
There is a 100 - 14 = 86% chance of a tornado not being produced.
0.80 * 0.86 = 0.688
Probability of a storm and no tornado = 68.8%

Hi there!
So we are given that:-
tan theta = 7/24 and is on the third Quadrant.In the third Quadrant or Quadrant III, sine and cosine both are negative, which makes tangent positive.
Since we want to find the value of cos theta. cos must be less than 0 or in negative.
To find cos theta, we can either use the trigonometric identity or Pythagorean Theorem. Here, I will demonstrate two ways to find cos.
Using the Identity
[tex] \large \displaystyle{ {tan}^{2} \theta + 1 = {sec}^{2} \theta}[/tex]
Substitute tan theta = 7/24 in.
[tex] \large \displaystyle{ {( \frac{7}{24}) }^{2} + 1 = {sec}^{2} \theta }[/tex]
Evaluate.
[tex] \large \displaystyle{ \frac{49}{576} + 1 = {sec}^{2} \theta} \\ \large \displaystyle{ \frac{625}{576} = {sec}^{2} \theta}[/tex]
Reminder -:
[tex] \large \displaystyle{ sec \theta = \frac{1}{cos \theta} }[/tex]
Hence,
[tex] \large \displaystyle{ \frac{576}{625} = {cos}^{2} \theta} \\ \large \displaystyle{ \sqrt{ \frac{576}{625} } = cos \theta} \\ \large \displaystyle{ \frac{24}{25} = cos \theta}[/tex]
Because in QIII, cos<0. Hence,
[tex] \large \displaystyle \boxed{ \blue{cos \theta = - \frac{24}{25} }}[/tex]
Using the Pythagorean Theorem
[tex] \large \displaystyle{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]
Define c as our hypotenuse while a or b can be adjacent or opposite.
Because tan theta = opposite/adjacent. Therefore:-
[tex] \large \displaystyle{ {7}^{2} + {24}^{2} = {c}^{2} } \\ \large \displaystyle{49 + 576 = {c}^{2} } \\ \large \displaystyle{625 = {c}^{2} } \\ \large \displaystyle{25 = c}[/tex]
Thus, the hypotenuse side is 25. Using the cosine ratio:-
[tex] \large \displaystyle{cos \theta = \frac{adjacent}{hypotenuse}} [/tex]
Therefore:-
[tex] \large \displaystyle{cos \theta = \frac{24}{25} }[/tex]
Because cos<0 in Q3.
[tex] \large \displaystyle \boxed{ \red{cos \theta = - \frac{24}{25} }}[/tex]
Hence, the value of cos theta is -24/25.

At a gas station during a road trip, Gerard has $32.00 to spend on fuel and windshield washer fluid for his car. Fuel costs $2.75 per gallon, and each bottle of windshield washer fluid costs $3.00. The car's average fuel efficiency is 38 miles per gallon. If Gerard must fill his car with enough fuel to drive 250 miles, what is the maximum number of bottles of windshield washer fluid Gerard can buy? (Note: all prices include taxes.)
Answer:
Step-by-step explanation:
Total amount with Gerald = $32
Cost of fuel per gallon = $2.75
Cost of each bottle of windshield = $3
38 miles per gallon. If Gerard must fill his car with enough fuel to drive 250 miles,
Total gallons of fuel = 250 miles / 38 miles
= 6.5789473684210 gallons
Total cost of fuel = Total gallons of fuel × cost per gallon
= 6.5789473684210 × $2.75
= $18.1
Amount left for windshield = Total amount with Gerald - Total cost of fuel
= $32 - $18.1
= $13.9
what is the maximum number of bottles of windshield washer fluid Gerard can buy?
= Amount left for windshield / Cost of each bottle of windshield
= $13.9 / $3
= 4.6333333333333 bottles
Maximum number of bottles =
4 bottles

(b) he equation of the akis of symmetry of the curve
Pls help me
Answer:
hodrvyeieiwb was the only one to win a lot
Answer:
the roots are x= -4 and x=6
the equation of the axis of symmetry is x^2-2x-24
Step-by-step explanation:
to find the roots you go to the area where the graph is touching the x axis because y is 0 on the x axis
to find the equation use the values of the x intercepts which are -4 and 6
(x+4)(x-6)
solve this into an equation by multiplying everything in the first brackets by every thing in the second the answer you are likely to come up with is x^2-2x-24

Use trigonometric identities to solve each equation within the given domain.
–sin2(x) = cos(2x) from [–π, π]. PLEASE SHOW WORK!!!
It looks like the equation is
-sin²(x) = cos(2x)
Recall the half-angle identity for sine:
sin²(x) = (1 - cos(2x))/2
Then the equation can be written as
-(1 - cos(2x))/2 = cos(2x)
Solve for cos(2x):
-1/2 + 1/2 cos(2x) = cos(2x)
-1/2 = 1/2 cos(2x)
cos(2x) = -1
On the unit circle, cos(y) = -1 when y = arccos(-1) = π. Since cosine has a period of 2π, more generally we have cos(y) = -1 for y = π + 2nπ where n is any integer. Then
2x = π + 2nπ
x = π/2 + nπ
In the interval [-π, π], you get two solutions x = -π/2 and x = π/2.

Answer: See image and explanation below
Step-by-step explanation:
The problem gives us 6 points to draw into the sketch.
The first and second point gives the domain and range of the sketch. The last 4 points tell us the coordinates.
Let's do the first two points. This tells us that the sketch should not go further (-3,0) and (3,0) of the x-axis, and should not go further (0,0) and (0,4) of the y-axis.
For the last 4 points, we can convert them to coordinates and graph them. The points would be (-2,3), (1,2), (-3,0), (3,0), and (0,4).
After we draw the 5 points listed above onto the graph, we can connect the points.
In the image I attached, the lines are straight, but when you draw it out, you should make your lines more curved.

that it is not orange or red?
PLZ HELP!!!!!
Explanation:
The probability of picking red is 0.13
The probability of picking orange is 0.20
The probability of picking either of these is 0.13+0.20 = 0.33
So the probability of picking neither of them is 1 - 0.33 = 0.67
There's a 67% of this happening.
Answer:
0.34
Step-by-step explanation:
because the probability of red is 20 and the probability of orange is 14 20 + 14 is 34.
The height, h, in metres, of a rocket t seconds after it is launched is approximately modelled by the quadratic relation h = 80t - 16t2. To the nearest second, how long is the rocket in the air?
Answer: 5 s
Step-by-step explanation:
Given
Height of the rocket can be modelled as [tex]h=80-16t^2[/tex]
Rocket will land on earth when it's height becomes 0
[tex]\Rightarrow 80t-16t^2=0\\\Rightarrow t(80-16t)=0\\\\\Rightarrow t=0\ \text{or}\ t=\dfrac{80}{16}=5\ s[/tex]
Neglecting 0 value
Thus, rocket remains in air for 5 s.

A A theatre show lasts 162 minutes. How many hours long is 162 minutes? Show any remaining minutes as a decimal.
Answer:
2. 42 hrs
Step-by-step explanation:
we know that there are 60 minutes in one hour.
60 mins = 1 hour
162 mins = 162/ 60
[tex] \frac{162}{60} = \frac{120 + 42}{60} \\ = \frac{120}{60} + \frac{42}{60} \\ = 2 hrs+ \frac{42}{60} hrs[/tex]
42/ 60 hourse would mean 42 mins ( multiply the fractions with 60)
= 42 mins
therefore,
2hrs 42 mins
= 2. 42 hrs.
