In which quadrant does the ordered pair (5, -6) lie?

guajiro [1.7K]

The coordinate (5,-6) lies in the fourth coordinate, because the first is x positive y positive, the second is x negative and y positive, the third is x negative and y negative, and the fourth is x positive y negative. This is x positive y negative, so it is in the fourth quadrant.

Solve the problem.

In-s [12.5K]

Answer:

16.9%

Step-by-step explanation:

Let's find the answer by using the following formula:

final people=(initial people)+((initial people)*(percent increase)) which can be written as:

percent increase=((final people)-(initial people))/(initial people) so:

percent increase=(83-71)/71=0.169=16.9%

In conclusion, the percent increase is 16.9%.

The main show tank has a radius of 60 feet and forms a quarter-sphere. what is the volume of the quarter-sphere shaped tank? rou

schepotkina [342]

By definition, the volume of a quarter of a sphere is given by:
$V = (1/4) * (4/3) * (\pi) * (r ^ 3)
$
Where,
r: sphere radius
Substituting values we have:
$V = (1/4) * (4/3) * (3.14) * (60 ^ 3)
$
Making the corresponding calculation we have:
$V = 226080 feet ^ 3$
Answer:
The volume of the quarter-sphere shaped tank is:
$V = 226080 feet ^ 3$

Question 10 The hypotenuse of a right triangle is I m longer than the longer leg. The other leg is 7 m shorter than the longer l

bonufazy [111]

Answer:

5, 12, 13

Step-by-step explanation:

let x be the longer leg then x + 1 is the hypotenuse and x - 7 the shorter leg

Using Pythagoras' identity in the right triangle

x² + (x - 7)² = (x + 1)² ← expand using FOIL

x² + x² - 14x + 49 = x² + 2x + 1

2x² - 14x + 49 = x² + 2x + 1 ( subtract x² + 2x + 1 from both sides )

x² - 16x + 48 = 0 ← in standard form

(x - 4)(x - 12) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 12 = 0 ⇒ x = 12

x = 4 , then x - 7 = 4 - 7 = - 3 ← not possible

x = 12, then x - 7 = 12 - 7 = 5 and x + 1 = 12 + 1 = 13

The lengths of the 3 sides are

longer leg = 12 m , shorter leg = 5 m and hypotenuse = 13 m
