Which ordered pair is a solution of the equation? 7x– 5 = 4y

If g(x) = 725, which of the following is true?

kotykmax [81]

Answer:

B and D

Step-by-step explanation:

The g(x) = 725 makes no sense to me....

however g(x) = -2x/(x-3) can be solved by plugging x = value into function

a) g(x) = -2x/(x-3)

g(0) = -2(0)/(0-3) = -3

= 0/-3 = 0 ≠ -3 FALSE

b) g(x) = -2x/(x-3) = 1

g(1) = -2(1)/(1-3) = 1

= -2 / -2 = 1 equals 1 TRUE

c) g(x) = -2x/(x-3)

g(2) = -2(2)/(2-3) < g(4) = -2(4)/(4-3)

= -4 / -1 < -8 / 1

= 4 is greater than - 8 FALSE

d) g(x) = -2x/(x-3) both values were already calcuated

g(1) = -2(1)/(1-3) = 1 < g(2) = -2(2)/(2-3) = 4

1 < 4 TRUE

2. How much water could my well hold if the depth of the well is 30ft and the diameter of the well is 24ft?

Ann [662]

Answer:

$V=4,320\pi\ ft^{3}$ or $V=13,564.8\ ft^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder (the well) is equal to

$V=\pi r^{2} h$

where

$r=24/2=12\ ft$ ----> the radius is half the diameter

$h=30\ ft$

substitute

$V=\pi (12)^{2}(30)$

$V=4,320\pi\ ft^{3}$

assume

$\pi =3.14$

$V=4,320(3.14)=13,564.8\ ft^{3}$

A running circuit is in the shape of a triangle with lengths of 6km, 6.5km and 7km. What are the sizes of the angles (in minutes

Rudik [331]

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ . The measures of the internal angles of the triangle given in the question are A = $52.6^{o}$ , B = $59.4^{o}$ , and C = $68^{o}$ .

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ .

Considering the given question, let the sides of the triangle be: a = 6 km, b = 6.5 km, and c = 7 km.

Apply the Cosine rule to have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2ab Cos C
