Solve the math problem

For the conditional statement, we have that:

The conditional statement has the following format:

p -> q.

For this problem, we have that the events are given as follows:

Hence p -> q is a true statement, as the set of whole numbers are the naturals plus the 0.

The inverse is given by:

~p -> ~q.

In which ~ represents the negation symbol.

Hence:

If a number is not a natural number, then the number is also not a whole number.

This statement has a false truth value, as the number 0 is whole but not natural.

The converse is given by:

q -> p.

Hence:

If a number is a whole number, then it is also a natural number.

This statement has a false truth value, as the number 0 is whole but not natural.

The contra-positive is given by:

~q -> ~p.

Hence:

If a number is not a whole number, then it is also not a natural number.

This statement has a true truth value, as all natural numbers are whole numbers.

The bi-conditional is given by:

p <-> q

In which <-> represents the term if, and only if.

Hence:

A number is a natural number if, and only if, it is also a whole number.

This statement has a true truth value, as all natural numbers are whole numbers.

a light is suspended at a height h above the floor. the illumination, i, at a point p is inversely proportional to the square of the distance, r, from the point p to the light and directly proportional to the cosine of the angle theta , I = k cos x / r² can be used to find the illumination at point p.

Light must be at the height of 7.07 for maximum illumination.

I = k cos x / r²

r² = h² + 10²

cos θ = h / [tex]\sqrt{h^{2} +10^{2} }[/tex]

then

I =  [tex]k \frac{h}{(h^{2} + 100)^{2/3}}[/tex]

on differentiating, we get,

[tex]\frac{dI}{dh} = k\frac{h^{2} + 100^{3/2 - 3h^{2}(h^{2} + 100 )^{1/2} } }{(h^{2} +100)^{3} }[/tex]

[tex]= k\frac{100 - 2h^{2} }{(h^{2} + 100)^{5/2} } \\\frac{dI}{dh} = 0\\ It gives that \\h = \sqrt{50} = 7.07\\on differentiating again,\\\frac{d^{2} I}{dh^{2} } = k \frac{(6h^{3} - 900h )}{(h^{2} + 100)^{7/2} }[/tex]

for h = 7.07,

[tex]\frac{dI^{2} }{dh^{2} } = -10267.6[/tex]

So , we can conclude that the light must be at the height of 7.07 for maximum illumination.

Step-by-step explanation:

The algebraic expression that models the situation when Jenny had $105, but she is spending $13 per week is 105 - 13w.

Let the number of weeks be represented by x

Therefore, since Jenny had $105, but she is spending $13 per week, the appropriate expression will be:

= 105 - (13 × w)

= 105 - 13w

The expression is 105 - 13w.

When two forces of equal strength act in the same direction within the same plane, with the counterforce in the centre, this is known as a parallel force system.

A see-saw is an illustration of this. The fulcrum in the middle provides the counterforce to keep the seesaw in a neutral position while the children apply the two forces at the ends. The significant vertical forces on an aeroplane while it is in flight is another illustration (see image at right).

Answer:

4x + 3y = 6

A = 4

B = 3

C = 6

Step-by-step explanation:

A line have a function:

y = ax + b

Because the line has a slope of - 4/3

=> a = - 4/3

=> y = - 4/3 x + b

Because the line go through point (6; - 6)

=> - 6 = - 4/3 .6 + b

=> b - 8 = - 6

=> b = 2

=> The function of the line

y = - 4/3 x + 6

=> 3y = - 4x + 6

=> 4x + 3y = 6

The temperature in degrees celcius in which bacteria cannot survive is greater than 3.66

This is a way of representing a variable with another

Given the inequality below;

Substitute C = 120oF

q/5(120) + 32  ≥ 120

24q + 32 ≥ 120

24q  ≥ 120 - 32

24q  ≥ 88

The remainder theorem conclude given that F(-5)=17

When, x= -5

x+5=0

So, F(-5) = 17

According to the remainder theorem, the result of dividing p(x) by (x - a) is p. (a). According to the factor theorem, (x - a) can only be a factor of p(x) if f(a) = 0. It is used to locate the rest. A linear polynomial's status as a factor of the input polynomial is determined using this method.

The remainder theorem is used to calculate the remainder when a polynomial is split by a linear polynomial. We are aware that long division of polynomials can be used to find the remainder after dividing one polynomial by another. The remainder can instead be discovered using the remainder theorem.

The zeroes of the polynomial functions are listed below:

Polynomials are algebraic constructions whose form is summarized by the following sum:

p(x) = ∑ cₙ · xⁿ, for n ∈ {0, 1, ..., m}

An alternative form to describe polynomials is using products of binomials of the form (x - r), where r is a root (zero) of the polynomial. The root of the polynomial is a value such that the result of the expression is equal to zero.

Then, we proceed to find the zeros of each polynomial function:

1) f(x) = 2 · x · (3 - x) · (x + 1). Roots: 2, 3, - 1.

2) f(x) = 2 · (x - 3) · (x + 2)² · (x - 1). Roots: 3, - 2 (multiplicity 2), 1

According to the question, to calculate break-even quantity with the given data. And the data is in dollars which is as follows:

Fixed cost (f(c)) = [tex]$1400[/tex] per week;

Variable cost (v(c)) = [tex]$2[/tex] per unit

Revenue = [tex]$6[/tex] per unit

Let us consider the break-even quantity to be ‘a’.

As per break-even point formula: Total costs = Total Revenue

And Total costs = Fixed cost + variable cost ;

      Total Revenue = (price per unit)(quantity sold)

Using above formulas, the above expression can be re-written as:

Fixed cost + variable cost = (price per unit)(quantity sold)

[tex]($1400)+($2a) = ($6a)[/tex]

[tex]4a = 1400[/tex]

[tex]a = 350[/tex]

Therefore, the break-even quantity is [tex]350[/tex] units.

Standard deviation =5

z-score = -0.6

We know z-score = (x-mean)/ Standard deviation

Substitute the values
