If JK = 7 and JL = 12, what is JM?
Without additional context or details about how JK, JL, and JM are related, it's impossible to accurately calculate or deduce the value of JM. Further clarification or more information about the scenario or the mathematical or geometric principles involved is needed for a precise answer.
Explanation:The question provided does not seem to present enough context or connection to standard mathematical operations or geometric principles that would enable a straightforward calculation or deduction of the value of JM. Without additional information about the relationship between JK, JL, and JM (such as whether they are sides of a triangle, or represent values in a given mathematical formula), or without a clear mathematical or geometric context, it's impossible to accurately determine the value of JM.
Generally, in mathematics, when calculating distances or values based on given lengths, one needs to apply specific formulas or theorems (such as the Pythagorean theorem in the context of right-angled triangles, or vector addition in the context of physics problems). Unfortunately, the given data lacks the necessary context to apply such principles.
For a precise and accurate answer, I recommend clarifying the problem's context or providing more details about the scenario in which JK, JL, and JM are related.
-Final answer:
To find JM in a triangle with known side lengths JK = 7 and JL = 12, we use the Triangle Inequality Theorem to determine that JM must be less than 19.
Explanation:
To find JM, we can use the fact that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side (Triangle Inequality Theorem).
JK + JL > JM
7 + 12 > JM
19 > JM
Therefore, JM must be less than 19 but more than the absolute difference of JK and JL, so JM < 19.

A line that includes the points (10,g) and (9,4) has a slope of 2. What is the value of g?
g=
Answer:
g = 6
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 2
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (10, g) and (x₂, y₂ ) = (9, 4)
m = [tex]\frac{4-g}{9-10}[/tex] = [tex]\frac{4-g}{-1}[/tex] = 2 ( multiply both sides by - 1 )
4 - g = - 2 ( subtract 4 from both sides )
- g = - 6 ( multiply both sides by - 1 )
g = 6

need help asap! due tomorrow and it’s late!
Answer:
8.8
Step-by-step explanation:
if you use the sin, cos, and tan method. 20 is the h, x is the a and the blank side is the o. if you take way the side without the o you have the a and h which means you have cosine. If you did the equation as cos64=x/20 Then multiply both sides by 20 to get the X by it so you will have 20 COS 64 and once you want a play that together you have 8.8 equals X.
What is the equation of a line that passes through the points (-3, 4) and (2, 8)?
Answer:
y= 4/5x +2/5
Step-by-step explanation:
When finding slope, use the format y-y1/x-x1. Plug in your coordinates to get this: 8-4/2--3. 8-4 equals 4, and 2--3 equals 5. So, your slope would be 4/5. Next, make your equation like this: y=4/5x+b. Next, plug in one of your ordered pairs into the equation. It doesn't matter which one you use. I'm going to use the second pair, so it would look like this: 8=4/5(2)+b. Multiply 4/5 by 2 to get 8/5. This is what you should have: 2=8/5+b. Subtract 8/5 from both sides to get your y-intercept of 2/5. Go back to your original equation and plug in 2/5 to b. This is your final equation: y= 4/5x +2/5. Hope this helped!
PLEASE HELP, WILL MARK BRAINLIEST!! The diagram shows the dimensions of a deck. A student finds the area by adding 16 ft2 + 48 ft2. Is the student correct? Explain your reasoning.
Answer:
The student is wrong, the total area = 16 ft² + 20 ft²
Step-by-step explanation:
The figure can be consists of :
1) A square of side length of 4 ft
2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)
So,
The area of the square = 4 * 4 = 16 ft²
The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²
So ,the total area = 16 + 20 = 36 ft²
So,
The student is distracted.
he have found the area of total rectangle of length of 8 ft and width of 6 ft instead of the area of the trapezoid.
So, the student is wrong
h(x)=square root of x-10
what is the domain of h?
The domain of the function h(x) = √(x-10) is all real numbers x that are greater than or equal to 10, because we cannot take the square root of a negative number under the real number system.
Explanation:In mathematics, the domain of a function is the set of all the possible input values (usually denoted as x) that would lead to a real and defined output. As for the function h(x)=√(x-10), we have a square root operation involved. We know that under the real number system, we cannot take the square root of a negative number.
Hence, for the function h(x)=√(x-10) to be real and defined, (x-10) must be greater than or equal to 0. That is, x-10 ≥ 0. Solving for x, we get x ≥ 10.
Therefore, the domain of the function h(x) = √(x-10) is x≥10. That is, h(x) is defined for all real numbers x that are greater than or equal to 10.

9. Rama is using a hand glider to fly directly from the top of one cliff onto another cliff below. The glider is guided by a cable. The cliffs are 740 feet apart and the first cliff is 280 feet taller than the second cliff. How long is the cable between the cliffs?
Answer:
791.2 ft
Step-by-step explanation:
The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.
[tex]H=\sqrt {x^{2}+y^{2}}[/tex]
where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then
[tex]H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft[/tex]
Answer:
791.2 ft to the nearest tenth.
Step-by-step explanation:
From the diagram,we assume :
AD to be the height of the first cliff
BC to be the height of the second cliff
DC to be the length of the cable between the top of the two cliff.
AD=740 ft.
DE= 280 ft.
Using Pythagorean Theorem, we obtain.;
[tex] {DE}^{2}+ {CE}^{2} = {DC}^{2} [/tex]
By substitution we obtain
[tex] {280}^{2} + {740}^{2} = [/tex]
[tex] \implies78400 + 547600 = {DC}^{2} [/tex]
[tex]\implies626000= {DC}^{2} [/tex]
Taking positive square root.
[tex]\implies DC = \sqrt{626000} [/tex]
[tex] \implies DC =791.202 ft[/tex]
Determine the solution for x^2+36>12x
Answer:
x^2+36 or x2 + 36 = 0
Step-by-step explanation:
Answer:
x> 6 twice
Step-by-step explanation:
x^2+36>12x
x² + 36 > 12x
Collect like terms
x² - 12x + 36 > 0
Solve quadratically using factorisation method by finding two factors of 36 that when added gives -12, the coefficient of x.
Factors = -6 and -6 which both add up to -12
Rewrite equation
x² - 6x - 6x +36> 0
Factorise by taking out the common factor
x ( x - 6) -6( x - 6) > 0
(x -6)(x - 6) > 0
x - 6 > 0 or x -6 > 0
Add 6 to both sides
x -6+6> 0+6 or x-6+6>0+6
x > 6 or x> 6
x> 6 twice

Find the area of the ring-the shaded region
The area of the (ring) - the shaded region is 75.36 in²
Solution:
The value of π = 3.14
Radius of the inner circle = 5 in
Area of the inner circle = πr²
= π × 5²
Area of the inner circle = 25π
Radius of the outer circle = (5 + 2) = 7 in
Area of the outer circle = πr²
= π × 7²
Area of the outer circle = 49π
Area of the shaded ring = Area of the outer circle – Area of the inner circle
= 49π – 25π
= 24π
= 24 × 3.14
= 75.36 in²
The area of the (ring) - the shaded region is 75.36 in².
