-2x^2+3x+5

What do the zeros of the expression represent?

A.
the initial height from which the shot was thrown
B.
the time it takes for the shot to reach the ground

Answer:

The zero of the equation represents the maximum height attained by the shot put.

Step-by-step explanation:

William is competing in the shot put event at a track meet. The quadratic expression that models the vertical height of the shot from the ground is

H = -2x^{2}+3x+5

We can find the zeroes of these two equations.

For that put H = 0.

-2x^{2}+3x+5 = 0

(-2x + 5)(x + 1) = 0

x= -1 or x = 2.5

x= -1 is neglected as it is not practical.

x = 2.5 is the maximum height attained by the shot put.

The zero of the equation represents the maximum height attained by the shot put.

The sum of three numbers is 8. The first number minus the second plus the third is 4. The first minus the third is 2 more than t
Natalija [7]
The numbers are 3+2+3=8 , the first number minus the second and the third is 4 then you get 3-2+3=4
So your overall anwser is 3+2+3=8

8x/3 - 2x/4 =-13 how do you solve
timama [110]

Answer:

-6

Step-by-step explanation:

8x/3 - 2x/4 = -13

find the L.C.M

<u>32x - 6x </u>  = -13

   12

<u>26x </u>  = -13

 12

cross multiply

26x = -156

divide both sides by 26

26x/26 = -156/26

x = -6

What is the answer for this?​
pantera1 [17]

Answer:

The general formula for nth term of given sequence is:

G_n = 54 . (\frac{1}{3})^{n-1}

Step-by-step explanation:

Given sequence is:

54,18,6.....

In order to write the general formula of a sequence, first of all the common ratio has to be found. Common ratio is the ratio between consecutive terms of a geometric sequence.

Here\\a_1 = 54\\a_2 = 18\\a_3 = 6\\And\\r = \frac{a_2}{a_1} = \frac{18}{54} = \frac{1}{3} \\r = \frac{a_3}{a_2} = \frac{6}{18} = \frac{1}{3}

The general formula is:

G_n = A_1 (r)^{n-1}

Putting the values of a1 and r

G_n = 54 . (\frac{1}{3})^{n-1}

Hence,

The general formula for nth term of given sequence is:

G_n = 54 . (\frac{1}{3})^{n-1}
