Answer:

The rewritten statements is as follows:

(a) ∀ dinosaur x, x is extinct.

(b) ∀ real number x, x is positive, negative, or zero.

(c) ∀ irrational number x, x is not an integer.

(d) ∀ logician x, x is not lazy.

(e) ∀ integer x, x^2 \ne 2,147,581,953

(f)  ∀ real number x, x^2 \ne -1

Step-by-step explanation:

As a general rule, words like "all", "every", "the", etc. are represented with ∀.

However, some sentences may be need to rephrased before such sentence can be rephrased

So, the following replacement will be made:

(a)

All \to ∀

dinosaurs \to x

(b)

Every \to ∀

real\ number \to x

(c)

First, we need to rephrase this sentence to:

<em>Every irrational number is not integer</em>

<em />

So, the replacement is:

Every \to ∀

irrational\ number \to x

(d)

First, we need to rephrase this sentence to:

<em>Every logician is lazy</em>

<em />

So, the replacement is:

Every \to ∀

lazy \to x

(e)

First, we need to rephrase this sentence to:

The integer 2,147,581,953...............

So, the replacement is:

The \to ∀

Integer \to x

(f)  

Replace:

The \to ∀

-1 \to x^2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

Given the function P(t)=5(b)^t, The initial number of fish species released was 5.

The function S(t)=152(1.045)^t, The growth rate is 4.5%

The measures of two sides of a triangle are 15 and 16. between what two numbers must the measure of the third side fall?
QveST [7]
If it is a right triangle and you given me adjacent and opposite the formula is
{r}^{2}   =  {x}^{2}  +  {y}^{2}
third side = 21.93

if its not right triangle you need the angle to solve

SOMEONE PLZZ HELP WITH THESE 2 PROBLEMS ASAP PLSSSSS!!! HELP NEEDED!! WILL MARK BRAINLYIST!!
Pavlova-9 [17]

Good morning Sir/Ma'am!

Answer:

f(r) = 40r + 26

If she can only afford 10 rolls, then the maximum number of nickels Cindy will have is:

f(10) = 40(10) + 26 = 426 nickels


Step-by-step explanation:

Given function  f(r)=40r+26, where r is the number of rolls of nickels she gets.


as it is already mentioned that she can get up to 10 rolls of nickels.


Therefore domain of function contains r ≤10,such that r is a natural number.


i.e.Domain of f(r)=all integers from 1 to 10, inclusive.


Domain of a f(x) is a set of values of x which make function f(x) well defined.
