I’m not entirely sure how to answer this without a word problem, but from what I see, all you have to do is multiply the two numbers.
12 x 43= 516
5 x 88 = 440
8x 63= 504
7 x 28= 196
Usually, when you see a number followed by another number in parentheses, like here, that means to multiply.

Which of the following are identities? Check all that apply

Natasha2012 [34]

Answer:

A, C

Step-by-step explanation:

Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.

Examining

A) True

$\frac{1-tan^{2}x}{2tanx} =\frac{1}{tan2x} \\ \frac{1-tan^{2}x}{2tanx} =\frac{1}{\frac{2tanx}{1-tan^{2}x}}\\ tan2x=\frac{1-tan^{2}x}{2tanx}$

Double angle $tan2\alpha =\frac{1 -tan^{2}\alpha }{2tan\alpha}$

B) False,

No further development towards a Trig Identity

C) True

Double Angle Sine Formula $sin2\alpha =2sin\alpha *cos\alpha$

$sin(8x)=2sin(4x)cos(4x)\\2sin(4x)cos(4x)=2sin(4x)cos(4x)$

D) False No further development towards a Trig Identity

$[sin(x)-cos(x)]^{2} =1+sin(2x)\\ sin^{2} (x)-2sin(x)cos(x)+cos^{2}x=1+2sinxcosx\\ \\sin^{2} (x)+cos^{2}x=1+4sin(x)cos(x)$

132 in

Step-by-step explanation:

Take the total radius = 18+3 = 21= R (say)
Simply use the formula for the circumference i.e. 2*pi*R
2*22/7*21= 132

Lucas is making accessories for the soccer team. He uses 883.68 inches of fabric on headbands for 46 players and 2 coaches. He a

zimovet [89]

The total fabric used for headband and wristband of a player was: 27.84 inches

Step-by-step explanation:

The question will be solved step by step.

So,

Total ribbon used for headbands = 883.68 inches

Total number of people for whom headbands were made = 46 players + 2 coaches = 48 inches

so the headband for one person will use fabric: $\frac{883.68}{48}\\= 18.41\ inches$

Then

Total fabric used for wristbands = 433.78 inches

Total players = 46

$Fabri\ for\ one\ player's\ wristband = \frac{433.78}{46}\\=9.43\ inches$

Total fabric for one player = 18.41 + 9.43 = 27.84 inches

Hence,

The total fabric used for headband and wristband of a player was: 27.84 inches
