You would need 3 pails of plaster, specifically about 2 pails and a fifth of another but you cant buy a fraction of a pail, so 3 pails are needed.

Select all the expressions equivalent to: (4^5)⋅4^3 Group of answer choice 2^14 4^12 2^16 16^8 4^8 16^4

kumpel [21]

Answer:

Choices given as $2^{16}, 4^8$ and $16^4$ are correct.

Step-by-step explanation:

Given expression is,

$(4^5)(4^3)$

By applying law of exponents in the given expression,

$(4^5)(4^3)=4^{5+3}$

$=4^8$

$(4^5)(4^3)=(2^2)^5(2^2)^3$

$=(2^{2\times 5})(2^{2\times 3})$

$=2^{10}\times 2^6$

$=2^{16}$

$=(2^4)^4$

$=(16)^4$

Therefore, choices given as $2^{16}, 4^8$ and $16^4$ are correct.

Write an equation in slope-intercept form for the line.<br><br> slope = 0, y-intercept = 3

Anit [1.1K]

Answer: y = 0x+3 or y = 3

The slope is 0 and the y intercept is 3. So m = 0 and b = 3.

Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.

This graphs out a horizontal line that passes through the two points (0,3) and (1,3).

Consider the following argument:

mariarad [96]

Answer:

$r \Rightarrow p\\ q \Rightarrow p\\ r \vee p\\ (r \vee q) \Rightarrow \neg r\\ s$

Step-by-step explanation:

$r \Rightarrow p \equiv (\neg r \vee p)$ , p is false.

$q \Rightarrow p \equiv (\neg q \vee p)$ , p is false.

$(r \vee q)$ , r and q are falses.

$(r \vee q) \Rightarrow \neg r \equiv (\neg (r \vee q) \vee \neg r)$ . this sentence is true.

s
