The path of the ball in terms of the balanced or unbalanced forces that act on it is described by the following option;
The baseball is at rest in the pitcher's glove, meaning the forces are balanced. The forces are unbalanced during the pitcher's windup and release since the ball is moving. They then return to being balanced while the ball is traveling through the air at a constant speed. The forces become unbalanced when the ball hits the catcher's gloves and slows down. They then return to being balanced once the ball is completely at rest in the catcher's gloveHow can the path of the baseball be described?According to Newton's laws of motion, a body remains at rest or maintains a uniform motion in a straight line unless unbalanced forces are acting on it.
Therefore;
The forces are balanced when the ball is at rest in the pitcher's glove.
While the ball is made to move during the pitcher's windup and release, the forces are unbalanced.
The forces are balanced while the ball is traveling at a constant speed (uniform motion).
When the ball's speed is changed as it hits the catcher's gloves, the forces are unbalanced.
When the ball is at rest in the catcher's gloves, the forces are balanced.
The correct option is therefore the 6th option

Step-by-step explanation:
(2×8² - 2²×8)/(2×8)
before we start typing things into the calculator, we see that the fraction can be simplified :

If using the method of completing the square to solve the quadratic equation
x? + 15x + 25 = 0, which number would have to be added to "complete the
square"?
Answer:
31.25
Step-by-step explanation:
The general form of a complete square would be (x + a)^2 + b
Given an equation of X^2 + 15X + 25 = 0,
the idea is to reduce it into the form if (X + C)^2
which can be expanded into X^2 + 2XC + C^2
In this case 15 will be our 2C So our c will be 7.5.
Substituting in these numbers,
We have X^2 + 15X + (7.5)^2 = 0
However our original equation has 25 for its C^2, thus
we need to add 31.25 in order to get (7.5)^2
FYI
The final completed form will be (X + 7.5)^2 - 31.25

If f(x)=[[x] determine each of the following.
a. f(9.3)
b. f(4.8)
c. f(-7.5)
The values of the maximum integer functions:
f(9.3) = 9f(4.8) = 4f(- 7.5) = - 8How to use a maximum integer function?The statement indicates a function that uses real numbers as input and brings out the greatest integer less than or equal to the number as output:
f(9.3) = [[9.3]]
f(9.3) = 9
f(4.8) = [[4.8]]
f(4.8) = 4
f(- 7.5) = [[- 7.5]]
f(- 7.5) = - 8
Then, the results of the maximum integer function are f(9.3) = 9, f(4.8) = 4 and f(- 7.5) = - 8, respectively.

f(t)= (t-5)^2 - 9 what are the zeros of the function? Smaller T: Larger t: What is the vertex of the parabola?: (__,__)
Smaller t = 2
Larger t = 5
Step-by-step explanation:
Given:
The given function is.
Find the zeros of the function.
Solution:
Simplify the equation above equation.
Now, we first find the root of the above equation.
Use quadratic formula with .
Put a, b and c value in above equation.
For positive sign
t = 2
For negative sign
t = 5
Put t = 2 in given function.
Put t = 5 in given function.
So, the zeros of the function is t = 2 or 5
Therefore, the smaller value of t = 2 and larger value of t = 5.

A line passes through the point (12,–4) and is perpendicular to the line with the equation y = 6x + 3. What's the equation of the line?
I'm just gonna so you how I got it
Step-by-step explanation:
6x - 3y - 5 = 0 has slope 6/3 = 2. A perpendicular line will have slope -1/2 (since slopes of two perpendicular lines must have a product of -1), so its general form will be 3x + 6y - a = 0.
Now to find a. We know a point on the line, (4,10), and so we plug those coordinates in:
3*4 + 6*10 - a = 0
12 + 60 - a = 0
72 = a
3x + 6y - 72 = 0.
We can simplify this by dividing all numbers by 3, getting:
x + 2y - 24 = 0

b) Work out the value of (1.7 x 10¹) × (8.5 × 10-²)
Give your answer in standard form.
On solving the provided question we can say that ordinary number the answer is 1.495 x 10^0
What is an ordinary number?An ordinary number, also known as a standard form number or a decimal number, is a number that is written in the familiar base-10 format, with a whole number part and a fractional part separated by a decimal point.
A) 5.1 x 10¹ as an ordinary number is 51.
B) To work out the value of (1.7 x 10¹) × (8.5 x 10-²), we first need to multiply the two numbers:
(1.7 x 10¹) × (8.5 x 10-²) = 1.7 x 8.5 x 10¹ x 10-² = 14.95 x 10-1
To express the answer in standard form, we need to move the decimal point to the left so that there is only one non-zero digit to the left of it. 14.95 x 10-1 is 1.495 x 10^0. So the answer is 1.495 x 10^0

factorise x³-4x²+x+6
The binomial factors of x³- 4x²+x+6 are (x+2), (x+3), and (x-1).
Using the splitting and grouping the terms:
x³ + 4x² + x - 6
= x³ + 2x² + 2x² + x - 6 [Splitting 4x² = 2x² + 2x²]
= (x³ + 2x²) + (2x² + x - 6)
= x² (x + 2) + (2x² + 4x - 3x - 6)
= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]
= x² (x + 2) + (x + 2) (2x - 3)
= (x + 2) ( x² + 2x - 3)
= (x + 2) ( x² + 3x - x - 3)
= (x + 2) [x (x + 3) - 1 (x + 3)]
= (x + 2) (x + 3) (x - 1)

What are the new coordinates if the figure were rotated 90 degrees counterclockwise
Answer:
third option
Step-by-step explanation:
under a counterclockwise rotation of 90° about the origin
a point (x, y ) → (y, - x )
Then
A (- 1, - 2 ) → (- 2, - (- 1) ) → (- 2, 1 )
B (2, - 2 ) → (- 2, - 2 )
C (1, - 4 ) → (- 4, - 1 )
The new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)
How to determine the new coordinates rotating by 90 degrees counterclockwiseFrom the question, we have the following parameters that can be used in our computation:
The figure,
Where, we have
A = (-1, -2)
B = (2, -2)
C = (1, -4)
The rule of 90 degrees counterclockwise is
(x, y) = (-y, x)
Using the above as a guide, we have the following:
A = (2, -1)
B = (2, 2)
C = (4, 1)
Hence, the new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)

step 2. the zeros are -3, 0, 2, 5.
step 3. therefore there are 5 intervals
step 4. ( ,-3) - f(x) = "-"

What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The given function can be rewritten as,
f(x) = x²(x-5)(x+3)³(x-2)
f(x) = (x-0)² (x-5) (x+3)³ (x-2)
Now, the value of x in the given function, or the x-intercept can be found by substituting the value of the factors of function as 0.
0 = (x-0)² (x-5) (x+3)³ (x-2)
(x-0)² = 0

If θ=14∘, how far is the second baseman from second base?
Round to the nearest hundredth.
The distance to second base is approximately _________ feet.
The distance to second base is approximately 127.28 feet. Round to the nearest hundredth
How to determine the distance to second baseSince the angle is 45 degrees, the other side of the right triangle are equal, hence we have two sides of 90 ft to be used to find the hypotenuse
Using Pythagoras theorem given by the the formula
hypotenuse² = opposite² + adjacent²
plugging the values as in the problem
let x be the required distance
x² = 90² + 90²
