Step-by-step explanation:

The height that the golf ball travels from its starting point to the point where it begins to fall toward the ground can be calculated using the zeros of the equations. Option A is correct.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, a golfer hits a ball off a tee. The height of the golf ball in the coordinate plane is represented by a quadratic function, with the origin being the golf ball's initial position.

The equations give the relation of height, time, and velocity in terms of the quadratic equation is,

h = -t² + vt + s,

Since s is the height in feet and v is the initial velocity in feet/second, one may determine the ball's maximum height.

After solving the equation and finding the values of zeroes gives the maximum height.

Thus, the height that the golf ball travels from its starting point to the point where it begins to fall toward the ground can be calculated using the zeros of the equations. Option A is correct.

Step-by-step explanation:

Damon drank 2/3 liter of water Monday before going jogging. He drank 3/7 liter of water after his jog. How much water did Damon drink altogether?

Volume of water Damon drank before jogging = 2/3 liters

Volume of water Damon drank after jogging = 3/7 liters

Total volume of water Damon drank altogether = 2/3 liters + 3/7 liters

= 2/3 + 3/7

= 14+9/21

= 23/21

= 1 2/21

Total volume of water Damon drank altogether = 1 2/21 liters

Step-by-step explanation:

If  [tex]f(x) = \frac{1}{2x^2} - \frac{1}{4x +3}[/tex],  then the value of  [tex]f(8)[/tex] is  [tex]f(8) = \frac{-93}{4480}[/tex].

A quadratic equation is an algebraic equation in the variable of the second degree. The quadratic equation is in the form of [tex]ax^{2} + bx + c = 0[/tex], where [tex]a,b,c[/tex]  are the real numbers.

We have

[tex]f(x) = \frac{1}{2x^2} - \frac{1}{4x +3}[/tex]

According to Quadratic Equation,

[tex]f(x)=ax^{2} +bx+c[/tex]

And we have,

[tex]f(x) = \frac{1}{2x^2} - \frac{1}{4x +3}[/tex]

So,

[tex]f(8) = \frac{1}{2x^2} - \frac{1}{4x +3}[/tex]

i.e. putting [tex]x=8[/tex],

[tex]f(8) = \frac{1}{2(8)^2} - \frac{1}{4*8 +3}[/tex]

[tex]f(8) = \frac{1}{128} - \frac{1}{35}[/tex]

Solving the above part,

[tex]f(8) = \frac{ 35-128 }{ 128*35 }[/tex]

[tex]f(8) = \frac{-93}{4480}[/tex]

Hence, we can say that value of  [tex]f(8) = \frac{-93}{4480}[/tex] .

Answer:

179:321

Step-by-step explanation:

If Sn is the sum of the first n term of a sequence, the ratio will be expressed as:

Sn/S'n = 5n+4/9n+6

The sum of nth term of a sequence is expressed as

Sn = n/2[2a+(n-1)d]

The expression becomes

{n/2[2a+(n-1)d]}/{n/2[2a+(n-1)d']} = 5n+4/9n+4

Open the bracket

a+(n-1/2)d/a+(n-1/2)d' = 5n+4/9n+4

Since the 18th tern is expressed as

T18 = a+(18-1)d

T18 = a+17d

The expression becomes

T18/T'18 = a+(n-1/2)d/a+(n-1/2)d'

a+17d/a'+17d' = a+(n-1/2)d/a+(n-1/2)d'

Compare and contrast to get n

On comparing both sides of the equation

17 = n-1/2

n-1 = 17×2

n-1 = 34

n = 34+1

n = 35

If the nth term is 5n+4

18th term will be 5(35)+4 = 179

If the nth term is 9n+6

18th term will be 9(35)+6= 321

Hence the ratio of their 18th term will be 179:321

Answer:

Acording to my brain the answer is (-2,-1) In other Words The correct answer is Option B

Step-by-step explanation:

God Bless :)

The ordered pair that needs to be removed in order for the mapping to represent a function is either: (-2, -1) or (2, -2).

The term "function" refers to a relationship between a set of inputs and outputs. Just one output is connected to each input in a function, which connects inputs in that manner. Every function has a domain, co-domain, and range.

To represent a function, each input (x-value) must be associated with only one output (y-value). Therefore, in order for the mapping to represent a function, we need to remove any ordered pairs that violate this rule.

Looking at the options given, we can see that only one option has a repeated x-value:

O (-2, -1) and 0 (2, -2)

Both of these ordered pairs have the same x-value (either -2 or 2), but different y-values. This means that they violate the rule that each input must be associated with only one output.

Therefore, the ordered pair that needs to be removed in order for the mapping to represent a function is either:

O (-2, -1)

or

0 (2, -2)

We need to remove one of these ordered pairs to make the mapping a function.
