What is the distance between A and B? Round your answer to the nearest tenth.

1 answer:

7 0

Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(-1,5)....x1 = -1 and y1 = 5
(4,1)...x2 = 4 and y2 = 1
now we sub and solve
d = sqrt ((4 - (-1)^2 + (1 - 5)^2)
d = sqrt ((5^2 + (-4^2))
d = sqrt (25 + 16)
d = sqrt 41
d = 6.4 <=== ur distance

The number of rows in an auditorium can be represented by the function f(x) = 80x. the number of seats in each row can be repres

Dominik [7]

Applying multiplication of functions, the total number of seats in the auditorium is given by:

h(x) = 80x² + 560x.

<h3>How polynomial functions are multiplied?</h3>

They are multiplied applying the distributive property, that is, all the terms are multiplied and then the common terms are added.

In this problem, the functions are given as follows:

f(x) = 80x.

g(x) = x + 7.

Then the multiplication is:

h(x) = f(x)g(x) = 80x(x + 7) = 80x² + 560x.

Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

ladessa [460]

Answer:

B. $1.83\text{ m}^2$

Step-by-step explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

$\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}\times \text{Weight (kg)}}{3600}}$

Substitute the values:

$\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}\times 80\text{(kg)}}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{\frac{12,000}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{3.3333333}$

$\text{Body surface area}( m^2)=1.825741$

$\text{Body surface area}( m^2)=1.83$

Therefore, the body surface area of the person would be 1.83 square meters.
