1-cosx/1+cosx=secx-1/secx+1
Verify the identity. I tried all identities that I could, but could not find how it worked. Can you show me how to verify with all steps?

I usually do not ask on brainly, but I've tried everything else and still got nothing.

Answer:

equally likely

Step-by-step explanation:

there are 3 numbers less than or equal to 3. divide that by every number on the cube. Then you get 0.5.

move the decimal twice and turn it into a percent 50%

50% is equally likely.

Answer:

1. The probability that she throws a multiple of 3 and flips tails is 1/6

2. The probability that Cymra draws a red marble put it back and draws a red marble again is 25/196

3.  The probability that Cole flips three tails in a row, P(3T) is 1/8

4. The number of shots Linda is expected to make if she takes 175 shots is 56

Step-by-step explanation:

1. The number of sides on the special die Li rolls = 12 sides

The numbers on the die are 1 through 12

The number of faces on the penny = 2 (heads and tails)

The number of multiples of 3 on the die = 3, 6, 9, and 12 = 4

The probability that she throws a multiple of 3, P(3) = 4/12 = 1/3

The probability that she flips tails rather than heads = 1/2

∴ The probability that she throws a multiple of 3 and flips tails = 1/3 × 1/2 = 1/6

2. The number red marbles in the bag = 5

The number green marbles in the bag = 6

The number blue marbles in the bag = 3

The total number of marbles in the bag = 5 + 6 + 3 = 14

The probability that Cymra draws a red marble put it back and draws a red marble again is given as follows;

The probability with replacement of picking two red marbles = 5/14 × 5/14 = 25/196

3. The probability that Cole flips three tails in a row P(3T) = (1/2)×(1/2)×(1/2) = 1/8

The probability that Cole flips three tails in a row, P(3T) = 1/8

4. The percentage of times Linda makes her free throws in the past 5 basketball practices = 32%

The number of shots she is expected to make if she takes 175 shots = 175 × 32/100 = 56.

Answer:

13260 square inches

Step-by-step explanation:

In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch

The formula to solve the above question is

1/2absinθ

a = 100 inches

b = 740 inches

θ = 159°

The area of the triangle =

1/2 × 100 × 740 × sin 159°

= 13259.61 square inches

Approximately = 13260 square inches

Therefore, the area of DEF = 13260 square inches

Answer:

y=16x

Step-by-step explanation:

y=(8)(2)x

--HEART IF THIS HELPED OR BRAIN ME!!--

The ordered pairs (-3, 1), (-2, 2), (-1, 4), (0, 8), (1, 16), (2, 32) and (3, 64) on the graph are plotted below.

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

The given equation is y=8×2ˣ.

Here, in table

x        -3      -2     -1      0     1      2      3

y         1        2      4     8     16   32    64

So, the ordered pairs are (-3, 1), (-2, 2), (-1, 4), (0, 8), (1, 16), (2, 32) and (3, 64)

Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is y=0.

Horizontal Asymptote: y=0

Therefore, the ordered pairs on the graph are plotted below.

#SPJ5

Answer:

d

Step-by-step explanation:

Answer and Step-by-step explanation:

Theoretically, we should expect the coin to flip 250, or very close to 250 times, and land on heads.

This is because the probability of getting heads is [tex]\frac{1}{2}[/tex], or 50%.

There is a 50% chance of landing heads or tails, so that means it would land 250 times on heads out of 500 flips of the coin.

#teamtrees #PAW (Plant And Water)

Answer:

250 times

Step-by-step explanation:

The coins has the heads or tails, with two options there is a 50% probability of landing on heads or tails.

500 x 50% = 250 times

Answer:

The equation of the line is;

y = 0.8x + 1

Step-by-step explanation:

Here, we want to get the equation of the line

The general equation of a straight line is;

y = mx + b

m

is the slope and b is the y-intercept

The y-intercept is simply the point on the y-axis where the line crosses the y-axis

we have this point at (0,1)

so we have;

y = mx + 1

to get m, we get any other point on the line and substitute its coordinates before we solve for m

we can identify the point (-2.5, -1)

substituting the coordinates

-1 = -2.5(m) + 1

-2.5m = -1-1

-2.5m = -2

m= 2/2.5

m= 0.8

so we have the equation of the line as;

y = 0.8x + 1

Answer:

S.A = 65.94

Step-by-step explanation:

S.A = [tex]\pi r^{2} + \pi rl[/tex]

3.14 x 3 x 3 = 28.26

3.14 x 3 x 4 = 37.68

37.68 + 28.26 = 65.94

Answer:

[tex]slope = \dfrac{-2}{5}[/tex]

Step-by-step explanation:

The slope of a line passing through points , [tex] (x_1,y_1) [/tex] and [tex] (x_2,y_2) [/tex] is ,

[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{-5+3}{3+2}\\\\\implies \boxed{\boxed{slope = \dfrac{-2}{5}}}[/tex]

hope it helps you.that was what I could think about.if am wrong please tell me.good day.

Answer:

d=2m

area(A)=196m

l=60m

now,

A=d(l+b-d)

196=2(60+b-2)

196=2(58+b)

196=116+2b

2b=196-116

2b=80

b=40m

Answer:

The Answer to the first would be 36 i'm on the test myself and it makes sense for the 1st to be 54

the 2'd would be 72

the 3'rd would be 36

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

We already know the slope, all we need to do is find the y-intercept.

You have to plug the coordinates into the equation, y = 0x + b

y = 0x + b

3 = 0(-4) +b

3 = 0 + b

3 = b

The equation is y = 3
