1.The population of the world is approximately 6200 million people. It is increasing by approximately 93 million people each yea

STALIN [3.7K]

The fraction can simplify down to $\frac{93}{6200}$ convert it to a fraction and the yearly increase is 1.5%

2. Well on average there are 365 days in a year. Dividing 93 million by 365 will get your increase per day.
There are 24 hours in a day, so that figure is further divided by 24.
There are also 60 minutes in an hour therefore furthermore divided by 60.
= 176 therefore true

Suppose that a water fountain produces a stream of water that follows the shape of a parabola. Assigning the origin of a coordin

irina1246 [14]

Vertex = (6, 5)
axis of symmetry is line x = 6
A third point in the parabola is (12, 0)

equation using the vertex is y = -a(x - 6)^2 + 5 = -a(x^2 - 12x + 36) + 5 = -ax^2 + 12ax - 36a + 5
since the parabola passes through point (0, 0)
i.e. -36a + 5 = 0
a = 5/36 = 0.139

Therefore, the equation is y = -0.139x^2 + 12(0.139)x = -0.139x^2 + 1.667x

Solve for T <br> Please Need Help

lara [203]

Answer:

$T = \frac{6b+4}{R}$

Step-by-step explanation:

$B=\frac{RT-4}{6}$

$6B=RT-4$ (times 6 on both sides)

$6B+4=RT$ (add 4 to both sides)

$\frac{6B+4}{R} = T$ (divide R on both sides)

thus

$T = \frac{6b+4}{R}$
