CAN ANYONE PLZZZ HELP ME? I WILL MARK THE FIRST AND THE RIGHT ANSWER THE BRAINLIST!!!

Answer:

No

Step-by-step explanation: No, because each input is not compared to exactly one output. The ordered pair that would need to be removed is (5,7) or (5,8). This works because it means that one of the inputs got taken away and can go to exactly one output.

The distance travelled by John in 13 hours is 819 miles.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The total distance covered in 8 hours is 504 miles.

Then in one hour, distance covered is given as below,

⇒ Number of miles ÷ Number of hours

⇒ 504 ÷ 8 = 63

Then, the distance covered in 13 hours is given as,

⇒ Unit distance in 1 hour × Number of hours

⇒ 63 × 13 = 819

Hence, the miles travelled in 1 hour is given as 819 miles.

Given:

The distance s​ (in feet) of the ball from the ground after t seconds is

[tex]s=64t-16t^2[/tex]

To find:

(a) At what time t will the ball strike the​ ground?

(b) For what time t is the ball more than 48 feet above the​ ground?

Solution:

(a)

We have,

[tex]s=64t-16t^2[/tex]

Substitute s=0, to find the time t when the ball strike the​ ground.

[tex]0=64t-16t^2[/tex]

[tex]0=16t(4-t)[/tex]

Using zero product property, we get

[tex]16t=0\Rightarrow t=0[/tex]

[tex]4-t=0\Rightarrow t=4[/tex]

Therefore, the ball strike the​ ground in initial condition (t = 0) and after 4 seconds (t = 4).

(b)

Now, s > 48, to find the time t when the ball will be more than 48 feet above the​ ground.

[tex]64t-16t^2\geq 48[/tex]

[tex]0> 16t^2-64t+48[/tex]

Divide both sides by 16.

[tex]0> t^2-4t+3[/tex]

[tex]0> t^2-t-3t+3[/tex]

[tex]0> t(t-1)-3(t-1)[/tex]

[tex]0>(t-1)(t-3)[/tex]

Related equation is [tex](t-1)(t-3)=0[/tex]. Zeroes are t=1,3. These two number divide the number line is three parts. (-∞,1),(1,3),(3,∞)

[tex]0>(t-1)(t-3)[/tex] inequality is true for only (1,3).

It is only possible when t lies in the interval (1,3).

Therefore, the ball will be more than 48 feet above the​ ground between 1 and 3 seconds.

When x= ([tex]10\frac{1}{3}[/tex]) the value of y is 93.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

when x= 2/3, y=6.

Using constant proportionality

y = kx

k= y/x

k = 6 / (2/3)

k = 6 x 3/2

k = 9

Now, k= y/x

9 = y/ ([tex]10\frac{1}{3}[/tex])

9 = y / (31/ 3)

y = 9 x 31/3

y = 93

Hence, the value of y is 93.

Answer:

81

Step-by-step explanation:

here,

(a+b)=15 -------(1)

(a-b)=12 -------(2)

Equating the equation (1) and (2)

a + b = 15

a - b = 12

(b gets cancelled having opposite signs)

or, 2a = 27

or, a = 27÷2

a = 13.5

then, putting value of a in equation (1)

a+b=15

or, 13.5 + b=15

or, b=15-13.5

b=1.5

lastly,

4ab = 4×13.5×1.5

= 81

Answer:

20 feet

Step-by-step explanation:

We can use scale factors to represent the lengths. Since the flagpole's base is 4 times the tree's height, we can also say that the flagpole's height is 4 times the tree's height. Since the tree's height is 5 feet, the flagpole's height is 4 x 5, which is 20.
