Answer:

The correct options are 1 and 3.

Step-by-step explanation:

Let,

p: A shape is a triangle.

q: A shape has four sides.

It is given that the shape is a rectangle. It means q is true and p is false.

1. p ∨ q is true if and only if p is true, or q is true.

Here q is true, therefore this option is correct.

2. p ∧ q is true if and only if p is true and q is true.

Here p is false, therefore this option is incorrect.

3. p → q is true if and only if the p is false or q is true.

Here p is false and q is true, therefore this option is correct.

4. q → p is true if and only if the q is false or p is true.

Here p is false and q is true, therefore this option is incorrect.

Therefore the correct options are 1 and 3.

Veseljchak [2.6K]

Answer:

The remnant of an estate that the grantor holds after he's granted a life estate to another person if the estate will return to the grantor, is called D) Reversion

Step-by-step explanation:

The correct answer is D) Reversion because, according to the Real Estate definitions, reversionary interest refers to future interest that reverts to a grantor, reversionary right refers to the return of the rights of the possession and quiet enjoyment to the lessor at the expiration of a lease and remainder estate refers to the remnant of an estate that has been conveyed to take effect and be enjoyed after the termination of a prior estate.

It's a question from real and complex numbers which I can't solve. so someone PLZ HeLp

Semmy [17]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , $(a^m)^{n}$ = $a^{mn}$

Simplifying the product of the first 2 terms

$\frac{a^{p^2+pq} }{a^{pq+q^2} }$ × $\frac{a^{q^2+qr} }{a^{qr+r^2} }$

= $a^{p^2-q^2}$ × $a^{q^2-r^2}$

= $a^{p^2-r^2}$

Simplifying the third term

5( $(a^p+r)^{p-r}$

= 5 $a^{(p+r)(p-r)}$ = 5 $a^{(p^2-r^2)}$

Performing the division, that is

$\frac{a^{(p^2-r^2)} }{5a^{(p^2-r^2)} }$ ← cancel $a^{(p^2-r^2)}$ on numerator/ denominator leaves

= $\frac{1}{5}$

Solve for the equation. The. Divide by 4 on both sides. And whatever you get for the slope. Write the opposite which will give you the perpendicular slope. For example: 1/4x is perpendicular to -4x
