A man is parasailing on a lake. The rope he is holding is 150 feet long and he is 45 feet above the water. What is the horizontal distance between the man and the boat? Round your answer to the nearest tenth.
Answers
9514 1404 393
Answer:
143.1 ft
Step-by-step explanation:
Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.
150² = 45² + d²
d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet
The horizontal distance between the man and the boat is about 143.1 feet.
The line 1 has equation 5x + 6y + 30 = 0. Given

(i) the coordinates of the point where l crosses the
x-axis,
(ii) the coordinates of the point of intersection
of l with the line x = 2,
(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answers
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0
5x+6(0)+30=0
5x=-30
x=-6
hence the point is (-6,0)
ii)5(2)+6y+30=0
10+6y+30=0
6y=-40
y=-20/3
hence the point of intersection is (2,-20/3)
iii) y+1=-5/6(x-3)
6y+6=-5x+15
6y+5x=9
iv) y+1=0(x-3)
y=-1

A bicycle tire makes 40 full revolutions while traveling where Scott is standing to where Steve is standing. If a tire has a diameter of 20 inches what is the approximate distance between where Steve is standing?
Answers
Answer:
2513.27 inches
Step-by-step explanation:
Given that:
Diameter = 20 inches
Number of revolutions = 40
For a complete revolution :
Distance traveled = Circumference = 2πr
2 * π * 20/2 = 62.831853 inches
Distance per revolution * number of revolutions
62.831853 * 40
= 2513.2741 inches
= 2513.27 inches

Cual es el volumen del concreto que necesitamos para construir cuatro columnas circulares si el diámetro de cada una es de 50 cms y la altura y la altura son 3,5(la respuesta en ms)
Answers
Answer:
27488.92 cm³
Step-by-step explanation:
El volumen de concentre para columna circular = área de superficie del círculo × altura de la columna.
= πr² × h
Dado que:
diámetro = 50 cm
height = d/2 = 50 cm / 2 = 25 cm
= 3.5 cm
Entonces:
El volumen de concentre para columna circular = πr² × h
El volumen de concentre para columna circular = π(25)² × 3.5
El volumen de concentre para columna circular = 6872.23 cm³
Para cuatro columnas circulares; el volumen será: = 4 × 6872.23 cm³
= 27488.92 cm³
f(x)=x2 + 4x -6
f(x) can be written in the form (x + m)?+n.
Find the value of m and the value of n.
Answers
Answer:
m = 2 and n = -10
Step-by-step explanation:
The given function is f(x) = x² + 4·x - 6
The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation
We have;
f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4
f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10
f(x) = (x + 2)² - 10
By comparison with (x + m)² + n, we have;
m = 2, and n = -10
