8 0

Answer:

A

Step-by-step explanation:

x2 = -98

x =+-√-98

x = +-√49 • 2 • -1

x = +-7√2 • -1

x = +-7i√2

(Note: i = √-1 and i^2 = -1, so you can interchange the values)

Which one of the following would prove that two triangles are congruenta
White raven [17]

Answer:

Corroponding side lengths are equal

Step-by-step explanation:

Two triangles may have the same areas, but the sides might be different or in different spots than each other. The same goes for perimeter, therefore it doesn't mean that they are congruent. If two triangles had the same angle measures, it could still have any size side lengths. When corrosponding side lengths are equal, they have the same angles as well, so they are only congruent in this example.

Hope this helps :)

Given that cosθ=7/25 , what is sinθ ?
OLga [1]

Answer:

sin  θ = 24/25.

Step-by-step explanation:

Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.

So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)

= sqrt 576

= 24 .

Therefore sin  θ = 24/25.

Find $ \left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3} $.
vitfil [10]

Question:- Find

\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}

Answer:-

\left(\frac{5}{12}\right)^{4}\left(\frac{12}{15}\right)^{3}

Taking power inside the bracket

\frac{5^{4} }{ {12}^{4} }  \times  \frac{ {12}^{3} }{ {15}^{3} }

\frac{ {5}^{4} }{ {12}^{4 - 3} }  \times  \frac{1}{ {(5 \times 3)}^{3} }  \\  \frac{ {5}^{4} }{12}  \times  \frac{1}{ {5}^{ 3 } \times  {3}^{3}  }  \\  \frac{ {5}^{4 - 3} }{12 \times  {3}^{3} }  \\  \frac{5}{4 \times 3 \times  {3}^{3} }  \\  \frac{5}{4 \times  {3}^{4} }  =  \frac{5}{4\times81 }  \\  Answer-> \frac{5}{324}

Power\:Form-> \frac{ 5 }{12 \times {3}^{3} }
