45.3 x 2.34 3.7 x 0.26 0.4 x 0.9 12.98 x 13 0.05 x 1.2

Sedbober [7]

Answer:

I don't know exactly what you're looking for so here

45.3 x 2.34 = 106.002

3.7 x 0.26 = 0.962

0.4 x 0.9 = 0.36

12.98 x 13 = 168.74

0.05 x 1.2 = 0.06

45.3 x 2.34 x 3.7 x 0.26 x 0.4 x 0.9 x 12.98 x 13 x 0.05 x 1.2 = 371.672926612

Sin(cos^-1 x) how to solve?

tatiyna

Answer:

$sin(cos^{-1}x)=\sqrt{1-x^2}$

Step-by-step explanation:

let us assume

$cos^{-1} x=\theta\\x=cos\theta\\$

now

$sin(cos^{-1}x)$ can be written as $sin\theta$

we know $sin^2\theta+cos^2\theta=1$

so $sin^2\theta=1-cos^2\theta$

$sin\theta=\sqrt{1-cos^2\theta}$

now from above equation we can say that

$sin\theta=\sqrt{1-x^2}$

$sin(cos^{-1}x)=\sqrt{1-x^2}$

Answer:

I think rhombus.

Step-by-step explanation:

Because a rhombus has all sides equal but no right angles. Squares and Rectangle both have right angles. And trapezoids have all different sides.
