The equation used to determine height and time is y = 16x² + 96x + 10 and y = 17x + 5

What is Projectile Motion ?

A projectile is something that has only one force acting on it the entire time, which is gravity, with the exception of the beginning.There are numerous types of projectiles.A projectile is something that is launched from the position of rest.A projectile is also any object that is hurled vertically upward as long as air resistance has no effect. Additionally, a projectile is any object that is fired upward at an angle to a horizontal plane.

The height of projectile after t seconds is given,

h(t) = 1/2 gt² + v₀t + s₀

where,

v₀ ( initial velocity ) = 96 feet per second

s₀ ( initial height ) = 10 feet

g = 32 feet per second²

put the values,

h(t) = 1/2 (32)t² + 96 t + 10

h(t) = 16 t² + 96 t + 10

so, let h(t) = y and t = x

y = 16x² + 96x + 10

We know, Amy's bullet follows a linear path,

The linear equation is,

y = mx + b

where, slope (m) = 17 feet per second and,

y-intercept (b) = 5 feet

plug in the values in linear equation,

y = 17x + 5

Therefore, The equation used to determine height and time is y = 16x² + 96x + 10 and y = 17x + 5

Using the Fundamental Counting Theorem, the number of plates for each case is obtained as follows:

The Fundamental Counting Theorem is a theorem that states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the total number of outcomes is calculated by the multiplication of the factorials as presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

With the Latin letters, it is found that for the letters, there are 26 outcomes, hence:

[tex]n_1 = n_2 = n_3 = 3[/tex]

With one number, the number of outcomes for the digit is:

[tex]n_4 = 9[/tex]

(as the digit cannot be zero).

With two numbers, the number of outcomes for the digit are:

[tex]n_4 = 9, n_5 = 10[/tex]

With three numbers, the parameters are:

[tex]n_4 = 9, n_5 = 10, n_6 = 10[/tex]

Hence the total number of plates is obtained as follows:

T = 26³ x (9 + 9 x 10 + 9 x 10 x 10) = 17,558,424.

With the extra letters, each letter can assume 29 outcomes, hence the number of plates is:

T = 29³ x (9 + 9 x 10 + 9 x 10 x 10) = 24,364,611.

For the given geometric sequence the seventh term is equal to 19/81 and the 12th term is equal to "-57" the value of the 15th term is 1539.

What is a geometric sequence?

One particular sort of sequence is a geometric sequence. It is a sequence in which each term, with the exception of the first, is multiplied by a fixed integer to obtain the following term. The common ratio must be multiplied by the current term in the geometric sequence to obtain the next term, and the common ratio must be divided by the current term to obtain the previous term.

Solution Explained:

We know, a7 = 19/81, a12 = -57

So, ar^7 = 19/81 and ar^12 = -57     (r= common ratio)

Since r< a15 < 0 [the sign alternate]

Ignoring the signs,
r^12 = r^7 X r^5
57 = 19/81 X r^5

(57 X 81)/19 = r^5

243 = r^5

r = the fifth ratio of 243 = 3

therefore, r = -3

So, a15 = a12 X r^3
            =  -57 X (-3)^3
            = 1539

Hence, the value of the 15th term is 1539.

a) An equation relating the miles traveled to gallons of gas used is m = 14g.

b) With 3.7 gallons of gas, one can drive up to 51.8 miles.

An equation is a mathematical statement that makes two mathematical expressions equivalent or equal using the equation symbol (=).

Equations establish the equality of two or more values, variables, or numbers.

The total distance driven on one tank of gas = 168 miles

The quantity of gas used = 12 gallons

The number of miles per gallon of gas = 14 (168/12)

Let m = distance in miles

Let g = gallons of gas used

Equation: m = 14g

Solution:

Gallons of gas used = 3.7

m = 14g

= 14(3.7)

= 51.8 miles

Thus, based on the established equation, with 3.7 gallons of gas used, the driver can cover 51.8 miles.

By evaluating in x = 0, we can see that the function with the greater y-intercept is the first one:

y=-x+6

For any function y = f(x), we define the y-intercept as the value that y takes when we evaluate the function in x = 0.

For the first function:

y = -x + 6

The y-intercept is:

y = -0 + 6 = 6

While for the second function:

y = 2x - 3

Evaluating in 0 we get:

y = 2*0 - 3 = -3

So the y-intercept of the first function is 6, and the one of the second function is -3.
