Answer:

Region A: includes all elements that are part of p, but not part of q.

Region B: includes elements that are part of p AND part of q at the same time.

Region C: includes all elements that are part of q, but not part of p.

For example, ensemble p might represent all friends of yours who got a burger at Mc Donald's. Ensemble q might represent those who got fries at Mc Donald's. Some of them will have gotten only a burger (A), some have bought only fries (C), and some will have bought both (B).

Answer:

The area represented by p v q or p ∪ q.

Step-by-step explanation:

The diagram represents two statements: p and q.

Here,

A represents the region in which only p is true.

B represents the region in which both p and q are true.

C represents the region in which only q is true.

The combine region of A, B, and C represents the region in which either p is true or q is true.

Therefore the region of A, B, and C is the union of p and q. It can be represented as p v q or p ∪ q.

X = 5 -3 x is not quadratic what is the reason

OleMash [197]

Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x

+7x−8=0, b. (x+2)2=49(x+2)

=49, c. 5x2−x−7=05x

−x−7=0, d. x2+4x=−1x

+4x=−1.

Solve for c 6/15=2/c

saul85 [17]

$\frac{6}{15}$ = $\frac{2}{c}$ Multiply both sides by 15
6 = $\frac{30}{c}$ Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5

Dave has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly. How much money w

ioda

Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.

Step-by-step explanation:

The given is,

Investment = $ 8000

No. of years = 15 years

Interest rate, i = 3.1 %

( compounded monthly )

Step:1

For for calculating future value with compound interest monthly,

$A = P (1 +\frac{r}{n})^{nt}$ .................(1)

Where,

A = Future amount

P = Initial investment

r = Rate of interest

n = Number of compounding in a year

t = Time period

Step:2

From given values,

P = $8000

r = 3.1%

t = 15 years

n = 12 ( for monthly)

Equation (1) becomes,

$A = 8000( 1+\frac{0.031}{12} )^{(12)(15)}$

$= 8000 (1+0.002583)^{180}$

$= 8000(1.002583)^{180}$

$= 8000(1.591059)$

$=12728.48$

A = $ 12728.48

Result:

Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.

If h(x) is the inverse of f(x), what is the value of h(f(x))?<br> OO<br> 0 1<br> f(x)

kozerog [31]

Answer:

Step-by-step explanation:

h(f(x) = x.

For example the inverse of f(x) = 2x is g(x) = x/2

f((gx)) 2 (x/2)

= 2x / 2

= x.

If (a, -5) is a solution to the equation 3a = -2B - 7, what is a?

Andrew [12]

I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1
