Which lengths would form a right triangle?
O 9, 12, and 14
O 24,7, and 26
o 21, 16, and 12
O 30, 24, and 18
Answer:
O 30, 24, and 18
Step-by-step explanation:
18^2+24^2=30^2
324+576=900
Final answer:
Using the Pythagorean theorem, only the set of lengths 24, 7, and 26 satisfy the condition for a right triangle, as 24² + 7² equals 26².
Explanation:
The question seeks to determine which set of lengths can form a right triangle. When assessing whether a given set of three lengths can form a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse). The formula for the Pythagorean theorem is a² + b² = c², where a and b are the lengths of the legs, and c is the length of the hypotenuse.
We will check each set of given lengths:
For lengths 9, 12, and 14: 9² + 12² = 81 + 144 = 225, which is not equal to 14² (196), so this is not a right triangle.For lengths 24, 7, and 26: 24² + 7² = 576 + 49 = 625, which is equal to 26² (625), so this set of lengths can form a right triangle.For lengths 21, 16, and 12: 21² + 16² = 441 + 256 = 697, which is not equal to 12² (144), so this is not a right triangle.For lengths 30, 24, and 18: 30² + 24² = 900 + 576 = 1476, which is not equal to 18² (324), so this is not a right triangle.Therefore, the lengths that would form a right triangle are 24, 7, and 26.
FGH is a right triangle. True or False?
Your mouse pointer is covering the number at the hypotenuse, but I assume that it is 10.
We can test to see if the triangle is a right angled triangle by using Pythagoras' Theorem. This is because the Pythagorean Theorem only works with right angled triangles.
The theorem is:
[tex]a^{2} + b^{2} = c^{2}[/tex]
where:
a = length of one leg of the triangle
b = length of the other leg of the triangle
c = the length of the hypotenuse.
If triangle FGH is a right triangle then:
[tex]\sqrt{51}^ {2} + 7 ^{2} = 10^{2}[/tex]
[tex]\sqrt{51} ^{2}[/tex] is just 51
[tex]7^{2}[/tex] is 49
and [tex]10^{2}[/tex] is 100
if we add up 51 and 49 we get 100. And of course, 100 = 100,
Since the theorem works, then the FGH is a right triangle

Decide whether each of the following statements is true. If false, demonstrate why.
a. 6!= 6.5!
b. 4! + 2! = 6!
C. 6!/3!=2!
Answer:
a is the only true one if you meant 6 times 5!
Step-by-step explanation:
Before we being
n!=n*(n-1)*(n-2)*...(3)(2)(1)
Example: 5!=5(4)(3)(2)(1) and 10!=10(9)(8)(7)(6)(5)(4)(3)(2)(1)
Yes that operation is multiplication.
a) Does 6!=6*5!
Let's see
6!=6*5*4*3*2*1
5!=5*4*3*2*1
So 6*5!=6(5*4*3*2*1)=6*5*4*3*2*1=6!
So true!
b) Does 4!+2!=6! ?
4!=4(3)(2)(1)
2!=2(1)
6!=6(5)(4)(3)(2)(1)
Does
4(3)(2)(1)+2(1)=6(5)(4)(3)(2)(1)
24 +2 =720
26=720 (this is not true)
So 4!+2! is not 6!
c) Does 6!/3!=2! ?
6!=6(5)(4)(3)(2)(1)
3!=3(2)(1)
If you divide 6! by 3!, then the factors 3 and 2 and 1 cancel and you are left with 6(5)(4).
So the question becomes is 6(5)(4)=2!
2!=2(1)=2
6(5)(4)=2?
No way! That is saying 120=2 which is not true.
The evaluations of the statements are: (a) false because non-integer factorials are not defined, (b) false because the sum of 4! and 2! does not equal 6!, and (c) false because 6! divided by 3! is 120, not 2!.
Explanation:Let's evaluate each statement one by one.
a. 6!= 6.5!This statement is false. The factorial function is defined for non-negative integers. Since there is no definition for non-integer factorial such as 6.5!, this comparison is invalid. A correct statement may involve only integer factorials.
b. 4! + 2! = 6!This statement is also false. To show this, let's calculate each factorial:
4! = 4 x 3 x 2 x 1 = 242! = 2 x 1 = 26! = 6 x 5 x 4 x 3 x 2 x 1 = 720Adding 4! and 2! gives 24 + 2 = 26, which is not equal to 6! (720). This statement could be corrected by finding two factorials that add up to another factorial, if such a pair exists.
c. 6!/3!=2!This statement is false. By calculating the factorials, we have:
6! = 7203! = 6Therefore, 6!/3! is equal to 720/6, which simplifies to 120, not 2 (which is the value of 2!). The correct statement is 6!/3! = 120.

the pie?
A)225cm
B)30cm
C)15cm
D)112.5
[tex]\large\boxed{\text{C}).\,15\,\text{cm}}[/tex]
Step-by-step explanation:In this question, we're trying to find what the radius of the circular pie is.
In this question, we know that the area of the pie is 706.5 cm²
We can use the area to find our radius.
We would use the formula [tex]r=\sqrt\frac{A}{\pi}[/tex] to find the radius.
R= radius
A = Area
Your equation should look like this:
[tex]r=\sqrt\frac{706.5}{\pi}[/tex]
Now, you will solve.
[tex]r=\sqrt\frac{706.5}{\pi}\\\\\text{You can make it simpler by turning}\, \pi\,\text{into} 3.14\\\\r=\sqrt\frac{706.5}{3.14}\\\\\text{Divide 706.5 by 3.14}\\\\r=\sqrt225\\\\\text{Now, get the square root of 225}\\\\r=15[/tex]
When you're done solving, you should get 15.
This means that the radius of the pie is 15 cm.
I hope this helped you out.Good luck on your academics.Have a fantastic day!Final answer:
To find the radius of the pie given its area of 706.5 cm², we use the formula A = πr² and solve for r, yielding an approximate radius of 15 cm. This corresponds to option C) on the given list.
Explanation:
To find the radius of the pie given its area, we can use the area formula for a circle: A = πr². Since the area of the pie is given as 706.5 cm², we can rearrange the formula to solve for the radius (r).
The rearranged formula to solve for the radius is: r = √(A/π).
Substituting the given area, we have:
r = √(706.5 cm²/π)
r = √(706.5/3.14159265359)
r ≈ √(225)
r ≈ 15 cm
Therefore, the radius of the pie is approximately 15 cm, making option C) the correct answer.
what’s the measure of the missing angles?
Answer:
Angle 1 equals 90 degrees. Angle 2 equals 38 degrees.
Step-by-step explanation:
Angle 1 is at the cross of two perpendicular lines, making it 90 degrees. Angle 2 can be found by making the two equal side lengths and the middle line into one triangle. This means that two of the angles are 52 degrees. This leaves 76 degrees to be split in the triangle. The middle line cuts the angle in half, making it 38 degrees
A ship at sea, the Gladstone, spots two other ships, the Norman and the Voyager, and measures the angle between them to be 48°. The distance between the Gladstone and the Norman is 4590 yards. The Norman measures an angle of 55° between the Gladstone and the Voyager. To the nearest yard, what is the distance between the Norman and the Voyager?
Answer:
=3501 yards.
Step-by-step explanation:
The three ships form a triangle. From the Voyager the angle between the Norman and the Gladstone=180-(55+48)=77°
Let the position of the Voyager be V that of Norman be N and that of the Gladstone be G
Then, the distance between Norman and voyager is g
g/sin G=v/ Sin V
4590/Sin 77=g/Sin 48
g=(4590 Sin 48)/Sin 77
=3500.8 yards
The distance between the Norman and the voyager= 3501 yards.

-2y+x=2y-8 what is the y-int and x-int?
Answer:
x-intercept (-8,0)
y-intercept (0,2)
Step-by-step explanation:
To find the x-intercept, you set y equal to 0.
Like this:
-2(0)+x=2(0)-8
0 +x=0 -8
x= -8
So the x-intercept is (-8,0).
To find the y-intercept, you set x equal to 0.
Like this:
-2y+0=2y-8
-2y =2y-8
Subtract 2y on both sides
-4y=-8
Divide both sides by -4
y=2
So the y-intercept is (0,2)
What is the volume of the composite figure with the dimensions shown in the 3 views? (Round to the nearest tenth)
Answer:
278.9 units^3 to the nearest tenth.
Step-by-step explanation:
This is a cylinder on the bottom . resting on the cylinder is a prism.
Volume of the cylinder = π r^2 h where r = 1/2 * 7 = 3.5 and h = 6.
V = π * 3.5^2 * 6 = 230.907 units^3.
Volume of the prism = l*w*h
= 4*4*3 = 48 units^3.
Volume of the composite figure = 230.907 + 48
= 278.9.

What is an equation?
It is a relationship between two variables and having a equal to sign in between.
How to draw a graph?Firstly we need to find the points of the respective equations.
y=[tex]x^{2} +9x+18[/tex]
y=[tex]x^{2}[/tex]+6x+3x+18
y=x(x+6)+3(x+6)
y=(x+3)(x+6)
Put this equal to 0 and we get x=-3 and x=-6
y=[tex]x^{2} -2x+4[/tex]
It is a wrong equation.
y=(x-3)(x-6)
put this equal to 0 we get x=3 and x=6
Now we have to check in the graph whether points (-3,0)(-6,0) satisfies or (3,0)(6,0)
We can easily see that (-3,0)(-6,0) satisfies the graph.
Hence the correct equation is y=x2+9x+18

Which graph shows the piecewise function given below?
The graph that represents the given piecewise function is the one on the right. Therefore the correct answer is option b.
The piecewise function f(x) is defined as follows:
f(x) = -x if x ≤ 3
f(x) = 2 if x > 3
To graph this piecewise function, you would draw two separate segments:
For x values less than or equal to 3, you would graph the line y = -x, which has a negative slope and goes through the point (3, -3). This line represents the function f(x) = -x for x ≤ 3.
For x values greater than 3, you would graph the horizontal line y = 2. This line represents the function f(x) = 2 for x > 3.
The transition from the first segment to the second occurs at x = 3. At this point, you would typically draw an open circle to indicate that the function is defined separately for x ≤ 3 and x > 3.
The graph will consist of a line sloping downward to the left (y = -x) for x ≤ 3 and a horizontal line at y = 2 for x > 3.
Therefore, the correct answer is option b.

To multiply the given expressions, use the distributive property and combine like terms. The final result is 20x⁴ - 39x³ + 26x² - 6x.
Explanation:To multiply the expression (5x²-6x+2) (4x²-3x), we can use the distributive property. Multiply the first term in the first binomial (5x²) by each term in the second binomial (4x², -3x), and then multiply the second term in the first binomial (-6x) by each term in the second binomial. Finally, multiply the third term in the first binomial (2) by each term in the second binomial. Combine like terms and simplify as needed to get the final result.
Applying this process, we get:
5x² × 4x² = 20x⁴
5x² × -3x = -15x³
-6x × 4x² = -24x³
-6x × -3x = 18x²
2 × 4x² = 8x²
2 × -3x = -6x
Combining all the terms, we have:
20x⁴ - 15x³ - 24x³ + 18x² + 8x² - 6x

2, 2, 1, 4, 4, 2, 3, 0, 0, 4, 1, 0, 4, 0, 2
Now, we could count how many of each numbers there are.
0 = 4 (Most)
1 = 2
2 = 4 (Most)
3 = 1
4 = 4 (Most)
When you're done counting the numbers, you would notice that 0, 2, and 4 have the highest number of occurrence in the data set.
This means that the modes of the data set are 0, 2, and 4
