Solve for the length of the hypotenuse
Answer:
5000
Step-by-step explanation:
In a right triangle ,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex] = > c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
where -
c = hypotenusea & b = the other two sides of the triangleAccording to the question , let the hypotenuse of the triangle be 'c' . So ,
[tex]c = \sqrt{ {3000}^{2} + {4000}^{2} } [/tex]
[tex] = > c = \sqrt{9000000 + 16000000} [/tex]
[tex] = > c = \sqrt{25000000} = 5000[/tex]
Hence , c = 5000
Answer:
5000
Step-by-step explanation:
[tex]3000^{2}[/tex] + [tex]4000^{2}[/tex] = 25000000
[tex]\sqrt{25000000}[/tex] = 5000
Please help!! Why is sin(20) = sin(160) = -sin(200) = -sin(340)?
These relations all follow from the identity,
sin(x - y) = sin(x) cos(y) - cos(x) sin(y)
Notice that 160° = 180° - 20°, so if x = 180° and y = 20° above, we get
sin(160°) = sin(180°) cos(20°) - cos(180°) sin(20°)
We know sin(180°) = 0 and cos(180°) = -1, so we end up with
sin(160°) = sin(20°)
For the other, notice that 200° = 360° - 160°, and 340° = 360° - 20°.
Answer:
Step-by-step explanation:
sin 20 is the same as sin 60 because 180-60=20. sin 20 is the same as -sin200 because 200-180=20
sin 340 is the same as sin 20 because 360-340=20. So all four of these connect and they all equal 20. Also, they all equal .3420 (rounded)
Question 2 of 5
The side lengths of a triangle are 5, 8, and 12. Is this a right triangle?

45k+34=979 i need help
Answer:
I think its 21 because 45x21= 945+34= 979
Step-by-step explanation:
Complete the table below.
Answer:
column 1, (2 and 2)
column 2, (8 and 4)
Step-by-step explanation:
For the first one, y = 2[tex]x^{2}[/tex]. You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!

write a linear equation to model the situation. you have walked 4 miles on a trail. you continue to walk at a rate of 3 miles per hour for h hours.
Answer:
[tex]y= 4 + 3h[/tex]
Step-by-step explanation:
Step one:
Given data
We are given that the initial distance walked is 4 miles
Also, the rate/ speed with which you are currently walking is 3 miles per hour
let the time taken be hours
and let the total distance be y
Step two:
We want to write an expression for the total distance
The total distance is given as
[tex]y= 4 + 3h[/tex]

Can someone help me with this please
Answer:
Step-by-step explanation:
4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling you... that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base .. along the b side will be the same.. so solving y is just the same as A or 52°
then to solve for x we also need to use that the triangle add up to 180° on those inside angles..
180= 52+52+14x+6
maybe you can solve it from here.. but i'll do it quickly
70 = 14x
5=x
5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x x= 34°
then use that the interior of the triangle add up to 180 again
180 = 34 + 5y+3 + 4y + 8
180 = 45 +9y
135 =9y
15 = y

Graph linear equations
Answer:
y = -3x-2
Step-by-step explanation:
Well, the linear equation of a line is: y = mx + b
Where m is the slope and b is your y-intercept
So, you can just plug the numbers into the equation
m = -3 and b = - 2
y = -3x - 2
hope its correct! good luck! :)

Molly is currently one third the age of her mother. In 12 years, Molly will be half the age that her mother will be. How old is Molly's mother now?
Answer
Molly's mother is 36 years old now.
Step-by-step explanation:
Answer:
Molly's mother is 36 now.
Step-by-step explanation:
(I could go the algabraic way, but I'd prefer not to. I'd rather guess. )
If Molly would be 24 in 12 years and her mother would be 48 at that time, then Molly is 12 now. Her mother would be 36 now.
Well, that didn't take too long! I hope this helps!

Which graph does not represent a function?
Select the correct answer.
If the zeros of a quadratic function are 3 and 8, what are the factors of the function?
ΟΑ.
(X + 8) and (x - 3)
OB.
(x - 8) and (x + 3)
O C.
(X + 8) and (x + 3)
OD.
(x - 8) and (x-3)
Answer:
OD
Step-by-step explanation:
The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.
so it's (x-8) and (x-3)

FIND TWO NUMBERS WHOSE SUM IS 21 AND DIFFERENCE IS 17
11 , 10
2 ,23
19 ,2
Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2
