Marina86 [1]3 years ago
7 0

<u>Given</u>:

The arc length for the given sector is 7π

The central angle for the given sector is θ

The radius of the circle is r.

We need to determine the formula for r in terms of θ

<u>Formula for r:</u>

The formula for r in terms of θ can be determined using the arc length formula,

S=r \theta

Substituting the values, we have;

7 \pi =r \theta

Dividing both sides by θ, we get;

\frac{7 \pi}{\theta}=r

Thus, the formula for r in terms of θ is \frac{7 \pi}{\theta}

A _______ conveys the notion of "or." We use the symbol logical or ∨ to represent a _______.
Aloiza [94]

Answer:

v and or.

Step-by-step explanation:

A ∨conveys the notion of "or". We use the symbol logical ∨ to represent a disjunction.

The "or" in logical lenguage indicates that one thing can happen but another thing also can happen, that is what we call a disjunction. The symbol to represent it is ∨.

The "and" in logical lenguage indicates that a situation is true only if all the statements are true. In other words we see all the statements as needs, not as options, that is called a conjunction. The symbol to represent it is ^.

Hence using Compound interest formula

A = P( 1 + r/n)^not

Inputting values

A = 5000( 1 + 0.08/9) ^ 9*1

A = 5, 414.52

Christine went shopping and bought each of her eighteight nephews a​ gift, either a video costing​ $14.95 or a CD costing​ $16.8
pogonyaev
So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8

so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6

Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2

Christine bought 2 video games and 6 CDs. 14.95(2)+16.88(6)=131.18
