Verify the identity sec^2(x)tan^2(x)+sec^2(x)=sec^4(x)

Mathematics
1 answer:
Natalija [7]4 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

tan²x + 1 = sec²x ⇒ tan²x = sec²x - 1

Consider the left side

sec²x × tan²x + sec²x

= sec²x(sec²x - 1) + sec²x ← distribute and simplify

= sec^{4} x - sec²x + sec²x

= sec^{4} x = right side ⇒ verified

Can anyone help me with this problem???
jasenka [17]

Note that x is the hypotenuse of a right triangle. Applying the Pyth. Thm.,


x^2 = 2^2 + 6^2, or x^2 = 4 + 36 = 40.


Thus, the hypotenuse is +sqrt(40), or 2sqrt(10).

A soccer ball has an interior diameter of 22 cm. How many cubic centimeters of air does a soccer ball
Delvig [45]

Answer:

Volume of soccer ball = 5,572.45 Cm³ (Approx)

Step-by-step explanation:

Given:

Diameter of soccer ball = 22 Cm

Radius of soccer ball = 22 Cm / 2 = 11 Cm

Find:

Volume of soccer ball = ?

Computation:

Volume\ of\ soccer\ ball = \frac{4}{3} \pi r^3\\\\ Volume\ of\ soccer\ ball = \frac{4}{3} \times\frac{22}{7} \times 11^3\\\\ Volume\ of\ soccer\ ball = 5,572.45332

Volume of soccer ball = 5,572.45 Cm³ (Approx)

Therefore, Soccer ball contain 5,572.5 Cm³ of air.

Joel needs to buy some blank DVDS and zip disks to back up a large amount of data that has been generated by an accounting firm.
wlad13 [49]

Answer:

D = 4, Z = 24

Step-by-step explanation:

6D+3Z = 96

5D+4Z = 116

multiply top by 5 and bottom by -6

top equation = 30D+15Z = 480

bottom equation = -30D-24Z = -696

Cancel 30D and -30 D

top equation  = 15Z = 480

Bottom equation = -24Z = -696

15Z - 24 Z = 480 - 696

-9Z = 216

Z = 216/9

Z = 24

Now that we have the value of Z, we can substitute it in any equation to find D

6D + 3(24) = 96

6D + 72 = 96

6D = 96 - 72

6D = 24

D = 24/6

D = 4
