The value of a calculated by Noemi is not correct as the correct value is

     a = -1/45

We know that the general form of the quadratic equation is given as

                        y = ax² + bx + c

where, a and b are coefficients of the variable x and c is the constant term.

Now according to the question the path of the golf ball is parabola whose coordinates will be

       (0,0) = origin where it starts

       (60,80) = vertex or the maximum point

       (120,0) = end point

Now putting the value of (x,y) in the above formula to find the value of a,b and c

when (x,y) = (0,0)

       0 = a0² + b0 +c

       c = 0

when (x,y) = (60,80)

      80 = a60² + b60 +c

       80 = 3600a + 60b + 0        (1)

when (x,y) = (120,0)

      0 = a120² + b120 +c

      0 = 14400a + 120b + 0      

       120b = -14400a

          b = -120a

Putting the value of a in equation (1) we get

    80 = 3600a + 60(-120a)

    80 = 3600a - 7200a

    80 = -3600a

     a = - 1/45

 ⇒ b = 8/3

Hence the equation will be         y = -1/45x² + 8/3x

and the value of a calculated by Noemi is not correct as the correct value is a = -1/45

Writing 2,000 words will take about 50 minutes for the average writer typing on a keyboard and 1.7 hours for handwriting.

Answer:

5 hours. the response has to be 20 characters long.

Answer:    14 min

Step-by-step explanation:

After 14 minutes more the scene will have the same amounts rendered if the computer is rendering two scenes.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A computer is rendering two scenes. The computer has already rendered 540 thousand pixels (kpx) of a kitchen scene and renders another 90kpx each.

Let after t minutes the scene will have the same amounts rendered.

The linear equation in one variable can be framed as:

540 + 90t = 960 + 60t

After solving the above linear equation in one variable:

90t - 60t = 960 - 540

30t = 420

t = 14 minutes

Thus, after 14 minutes more the scene will have the same amounts rendered if the computer is rendering two scenes.

⇒ [tex]3^{(-2x)+2} = 3^4[/tex]

⇒ -2x + 2 = 4

⇒ -2x = 2

⇒ x = 2/(-2)

⇒ x = -1

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

Jack spent first a total of AED 1282.04 and when he bought the box it cost AED 205.96

To solve this problem we must perform the following algebraic operations with the given information

Information about the problem:

Calculating the total cost Jack spend before bought the box:

Total cost = (No. drill bits*cost of drill bits) +  (No. washers  *cost of washers ) +  (No. hammers *cost of hammers)

Total cost = (8 drill bits * AED 11.22/ drill bits) + (10 washers * AED 10.11 / washers) + (2 hammers * AED 545.59 / hammers)

Total cost = AED 89.76 + AED 101.1 + AED 1091.18

Total cost = AED 1282.04

Calculating the box cost:

Balance = Paid - (Total cost + box cost)

Balance = Paid - Total cost - box cost

box cost = Paid - Total cost - Balance

box cost = AED 1500 - AED 1282.04 - AED 12

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given equation is :

y = x/2 + 1

Now, computing the value of y corresponding to values of x by substituting values in above equation :

when x = -10 :

y = x/2 + 1

y = -10/2 + 1

The value of the x means hypotenuse according to the Pythagoras is 12.8.

According to the statement

We have to find that the value of the x.

So, For this purpose, we know that the

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse

From the given information:

The perpendicular length is 12.

And The base is a 4.5

And we have to find that the hypotenuse value.

Then

According to the theorem

Perpendicular^2 + base^2 = Hypotenuse^2

And substitute the value then

12^2 + 4.5^2 = Hypotenuse^2

144 + 20.25 = Hypotenuse^2

Then

Hypotenuse^2 = 144 + 20.25

Hypotenuse^2 = 164.25

Hypotenuse = 12.8.

39.16 approx. is the value of x in  [tex]e^{\frac{x}{4} -8}[/tex] = 6 solved by using natural logarithm

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.

The power to which e would need to be raised in order to equal x is the natural logarithm of x.

For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.

Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

We have been asked to find x in [tex]e^{\frac{x}{4} -8}[/tex] = 6 using natural logarithm

⇒  [tex]e^{\frac{x}{4} -8}[/tex] = 6

⇒ [tex]\frac{x}{4} - 8[/tex] = ㏑6

Step-by-step explanation:

If f(x) = 2x + 1 and g(x) = x² + 2x + 1, find g(f(x)).

You are asked to find g of f of x.

This means your x value for the equation g(x) is f(x), hence g(f(x)).

g(2x+1)=(2x+1)^2 + 2(2x+1) +1

g(2x+1) = 4x^2 + 4x + 1 +4x + 2 + 1

Combine like terms.

g(2x+1) = 4x^2 + 8x + 4

g(f(x)) = 4x^2 + 8x + 4

For eg: 13.58 ~ 13.6

Solving the given equation log 8(2x - 1) = 1/3

We are given a logarithmic expression: log 8(2x - 1) = 1/3
