How do you determine two angles which are coterminal to the given angles ?

Julli [10]

Answer:

Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found.

How do i solve 2+49x4+x

qaws [65]

Answer:

Step by step solution :

STEP1:Equation at the end of step 1

((49 • (x4)) - (2•7x2)) + 1 = 0

STEP 2 :

Equation at the end of step2:

(72x4 - (2•7x2)) + 1 = 0

STEP3:Trying to factor by splitting the middle term

3.1 Factoring 49x4-14x2+1

The first term is, 49x4 its coefficient is 49 .

The middle term is, -14x2 its coefficient is -14 .

The last term, "the constant", is +1

Step-1 : Multiply the coefficient of the first term by the constant 49 • 1 = 49

Step-2 : Find two factors of 49 whose sum equals the coefficient of the middle term, which is -14 .

-49 + -1 = -50 -7 + -7 = -14 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and -7

49x4 - 7x2 - 7x2 - 1

Step-4 : Add up the first 2 terms, pulling out like factors :

7x2 • (7x2-1)

Add up the last 2 terms, pulling out common factors :

1 • (7x2-1)

Step-5 : Add up the four terms of step 4 :

(7x2-1) • (7x2-1)

Which is the desired factorization

Help please! Will give brainly! A rock is dropped from the top floor of a 500-foot tall building. A camera captures the distance

Anna [14]

Answer:

Step-by-step explanation:

1. No it does not as the rock will accelerate downwards (because of gravity) but we can also see that at the first second the rock fell 16 feet compared to the 2 to 3 seconds gap where it fell 80 feet (144-64).

2. All the way down to the ground. Each time gap is getting bigger and bigger (it's accelerating) and the gap between 5 and 6 s should be bigger than 4 to 5 and it is not as the rock cannot fall through the ground but only hit the ground

you may have to change the english a bit and english is not my first language

hope this will help

Assume that there are 365 days in a year, the probability that a person is born on any given day is the same for all days, and e

Artemon [7]

Answer:

Step-by-step explanation:

If each day equal chance then p = Prob that a person is borne on a particular day = 1/365

Each person is independent of the other and there are two outcomes either borne in July or not

p = prob for one person not borne in July = (365-31)/365 = 334/365

a)Hence prob that no one from n people borne in July = $(\frac{334}{365} )^n$

b) p = prob of any one borne in July or Aug = $\frac{(31+31) }{365} =\frac{62}{365}$ =0.1698

X- no of people borne in July or Aug

n =15

P(X>=2) = $15C2 (0.1698)^2*(1-0.1698)^{13} +15C3 (0.1698)^3*(1-0.1698)^{12} +...+15C15 (0.1698)^{15}$

=0.7505

Out of the choices provided the answers would be C,D, and E
She has four choices for the first brother's towel and three choices for the second brother's towel
ABC,ABD,ABE,ACD,ACE, and ADE are the possible outcomes.
If Fiona did not choose towel A for herself, there would be more outcomes.
Hope this helps!
