notsponge [240]

Answer:

fourth option

Step-by-step explanation:

Using the trigonometric identity

cos²x + sin²x = 1

Divide all terms by cos²x

$\frac{cos^2x}{cos^2x}$ + $\frac{sin^2x}{cos^2x}$ = $\frac{1}{cos^2x}$ which gives

Planet X has a mass of 8.46 x 1022 kg. Planet Y has a mass of 5,028,000,000,000,000,000,000,000 kilograms. How many times the ma

kramer

Answer:

59.4 times greater to the nearest tenth.

Step-by-step explanation:

5,028,000,000,000,000,000,000,000

= 5.028 * 10^24

So the required ratio = 5.028 * 10^24 / 8.46 * 10^22

= 0.594326 * 10^2

= 5.94326 * 10

= 59.4326.

Consider the proof.

fiasKO [112]

Answer:

Correct choice is B

Step-by-step explanation:

In step 4 were proved that $\triangle ABC\sim\triangle DEC.$

By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,

$\dfrac{AC}{DC}=\dfrac{BC}{EC}.$
