Answer:Set \displaystyle f\left(x\right)=0f(x)=0.

Step-by-step explanation:

Set \displaystyle f\left(x\right)=0f(x)=0.

If the polynomial function is not given in factored form:

Factor out any common monomial factors.

Factor any factorable binomials or trinomials.

Set each factor equal to zero and solve to find the \displaystyle x\text{-}x- intercepts.

A right-angled triangle has shorter side lengths exactly c^2-b^2 and 2bc units respectively, where b and c are positive real num

yKpoI14uk [10]

Answer: hypotenuse = $c^{2} + b^{2}$

Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side ( $s_{1},s_{2}$ ) of the right triangle, .i.e.:

$h^{2} = s_{1}^{2} + s_{2}^{2}$

In this question:

$s_{1}$ = $c^{2}-b^{2}$

$s_{2} =$ 2bc

Substituing and taking square root to find hypotenuse:

$h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}$

Calculating:

$h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}$

$h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}$

$c^{4}+b^{4}+2b^{2}c^{2}$ = $(c^{2}+b^{2})^{2}$ , then:

$h=\sqrt{(c^{2}+b^{2})^{2}}$

$h=(c^{2}+b^{2})$

Hypotenuse for the right-angled triangle is $h=(c^{2}+b^{2})$ units

In London. I pint of milk costs 58p.

joja [24]

Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.

In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :

Cost of 1 pint of Milk in London :

1 pint = 0.58 pounds

The equivalent value of 1 pint of Milk in terms of Euro in London will be :

1 pound = 1.17 euro

0.58 pound = x

Cross multiply :

x = 1.17 × 0.58

x = 0.6786 euro

x = 0.68 euro

Hence, 1 pint of Milk cost 0.68 euro in London

Cost of 1 pint of Milk in Paris :

1 Litre = 1.76 pint

Hence,

1.76 pint = 1.05 euro

1 pint = c

1.76c = 1.05

c = 1.05 / 1.76

c = 0.597 euro

Hence, cost of 1 pint of Milk cost 0.60 euro in Paris

Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

Find each function value.

EleoNora [17]

Answer:

see below

Step-by-step explanation:

g(x) = 3 − x^2

(a)g(30) = 3 - 30^2 = 3 - 900 = -897

(b)g(3)= 3- 3^2 = 3-9 = -6

(c)g(−1) = 3 - (-1)^2 = 3 - 1 = 2

(d)g(0.5) = 3 - (.5)^2 = 3 - .25 = 2.75
