5^2 + 8^2 = 12^2

25 + 64 = 144

89 does not equal 144

x=14/7

x=2

Answer:

0.6 ÷ 0.3 - Option 2.

0.2 × 0.9 - Option 3.

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

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

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! :)

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)

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!

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)

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!

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 -

According 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
