Find the coordinates of the vertex of the following parabola algebraically. Write your
answer as an (x, y) point.
y = 4x + 56x + 192

Answers

Answer:

 The vertex of the parabola   = (-7 , -4)  

Step-by-step explanation:

Step(i):-

Given that the parabola  y = 4 x² + 56 x +192

                                 y = 4 (x² + 14 x + 48 )

                                 y = 4 ( x² + 2 ×  7 (x) + 49-1)

                                 y = 4 ( x² + 2 ×  7 (x) + 49)- 4

we apply the formula

(a +b)² = a² + 2ab + b²

                                y = 4 ( x + 7 )² - 4

Step(ii):-

The general form of the parabola in algebraically

                              y = a ( x-h)² +k

The equation

                          y = 4 ( x + 7 )² - 4

                          y = 4 ( x-(-7))² - 4

  The vertex of the parabola (h,k) = (-7 , -4)  

Final answer:-

The vertex of the parabola  = (-7 , -4)

A ball is dropped from the top of a building that is 250 feet tall. The
height h of the ball in feet after t seconds is modeled by the function h =
- 16t2 + 250. How long will it take for the ball to reach a height of 75
feet? Round to the nearest tenth.

Answers

hi

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

  t² = -175 /-16

 t² = 175/16

Here there si two solutions :  t = [tex]\sqrt{175/16}[/tex]   and  t =  - [tex]\sqrt{175/16}[/tex]

However, as time cannot rewind,  we will  keep only positive solution

So t = [tex]\sqrt{175/16}[/tex]

   

in seconds  it will be  :  3.3 seconds

Answers

Answer:

Step-by-step explanation:

this is about the volume of each size of candle.  so the area of the circle , times the height of the candle is the amount of wax needed or it's volume.  

area of a circle is  = [tex]\pi[/tex][tex]r^{2}[/tex]

then the big candle is [tex]\pi[/tex][tex]2^{2}[/tex] = 12.56637

times 10 for it's height = 125.6637

so that's the big candles volume

then make 20 of those = 2513.27

a small candle is [tex]\pi[/tex][tex]1.5^{2}[/tex] = 7.068583471

and it's 6 cm tall so times 6 = 42.41150082

Now divide the small candle volume into the 20 big ones to see how many small ones can be made

2513.27 /  42.41150082 = 59.259

so just a bit over 59 small candles can be made from 20 big candles

Take 75 / 15. Then in that many times, they will meet again. The answer is 75/15 = 5, so at 7:15 AM , they will meet again. Think of this like Chemistry. There is a restricting reactant and a non restrictive reactant. If you have 200 slices of bread, and 150 slices of cheese, the bread could only support 100 sandwiches. You'd have 50 slices of cheese left over. So the bread is the restrictive, or, in this case, 75, and the cheese is the non-restrictive number, or, 15. Hope this helps :)

Write an explicit formula for an, the n^th term of the sequence 22, 20, 18, ....

Answers

Answer:

 [tex]a_n=a+(n-1)d[/tex]

Step-by-step explanation:

The given sequence is 22, 20, 18, ...

We need to find the explicit formula for an.

First term is 22

Second term = 20

Third term = 18

We can write the formula as :

[tex]a_n=a+(n-1)d[/tex]

Where

a is 22

d is common difference = 20-22 = -2

Forth term will be :

[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]

Hence, the formula is [tex]a_n=a+(n-1)d[/tex].
