suppose that two people standing 3 miles apart both see the burst from a firework display.after a period of time ,the first pers

Marrrta [24]

The fireworks display occur at 550.331 ft

The generic equation for a hyperbola provided by: is the best method for solving the problem in this instance.

$\frac{y^{2} }{b^{2} } - \frac{x^{2} }{a^{2} } = 1$ -

We presume that the y-axis is where the hyperbola's longer axis lies.

In this instance, the sound traveled a total of 1100 meters, and the value of a can be calculated as follows:

2a = 1100

a = 550ft

Given that the two people are 3 miles apart, we can calculate the value of c in feet as follows:

1 mile = 5280 feet

∴ 3 miles = 15840 ft = c

And this is how we may determine what b is worth:

$b^{2} = c^{2} - a^{2}$

$b^{2} = 15840^{2} - 550^{2}$

$b^{2} = 250603100$

Our equation is thus given by:

$\frac{y^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1$

And for this case we want to find the value of x when y = 3ft=15840ft and solving for x we get,

$\frac{15840^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1$

$\frac{15840^{2} }{250603100 } - 1 = \frac{x^{2} }{550^{2} }$

$1.001- 1 = \frac{x^{2} }{550^{2} }$

$0.001 = \frac{x^{2} }{550^{2} }$

$302865.145= {x^{2}$

x = 550.331 ft.

The fireworks display occur at 550.331 ft.

Please guys help me please

Answer:

$C' = (2,8)$

$A' = (4,4)$

$T' =(10,10)$

Step-by-step explanation:

Given

$k =2$

$C =(1,4)$

$A = (2,2)$

$T =(5,5)$

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

$New = Old * k$

So:

$C' = (1,4) * 2 = (2,8)$

$A' = (2,2) * 2 = (4,4)$

$T' = (5,5) * 2 = (10,10)$

Solving (b): The graph of the original image

Elmer has a collection of 300 fossils. Of these, 21 percent are fossilized snail shells.

chubhunter [2.5K]

In order to figure out the number of fossilized snail shell, multiply 21% by 300. first change 21% into a decimal, in order to do that, move the percent symbol two spaces to the left, and replace the "%" symbol to a decimal. 0.21 X 300= 63
so 21% of 300 is 63
