When t=2+√110/4, the ball will be 50 feet  height above the ocean.

Height is the measurement of someone or something from the top to toe or the base to head.height always refers to something is mesured either its high or low.

As per the given question

Because h=-16t^2+64t+96

So when h = 50

It means -16t^2+64t+96 =50

-16t^2+64+46=0

8t^2-32t-23=0

{∆=b^2-4ac,x= -b+√∆/2a}

So, ∆=(-32)^-4×8×(-23)=1760>0

So t =2- √110/4 <0

Thus tha answer is t = 2+√110/4

The equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

What is a linear equation in one variable?

The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For the first case:

If 2 movies are streamed, the cost is $14 per month

So the cost = number of movies * cost per movie

            y = 2*x

           14 = 2x

For the second case:

If 6 movies are streamed, the cost is $20 per month

So the cost = number of movies * cost per movie

            y = 6*x

           20 = 6x

Hence the equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

Answer:SLOPE

Step-by-step explanation:M in a equation is slope

Answer: y = 1/12x

Step-by-step explanation:

(24, 2)

(12, 1)

find slope (y2 - y1) / (x2 - x1)

2 - 1 / 24 - 12

1 / 12

find y intercept

y = mx + b

1 = 1/12(12) + b

1 = 1 + b

b = 0

y = 1/12x + 0

y = 1/12x

Both have a domain of [tex][0, \infty)[/tex] which in other words, is the set of nonnegative real numbers. I recommend using a graphing calculator to verify both of these functions have the same domain.

The graph for the linear equation y = -2x + 5 is plotted and shown in the image attached below.

If we are given an equation of a line that is expressed in slope-intercept form as y = mx + b, it means that the graph will have a slope = rise / run = the value of m, while it would cut across the y-axis at b, that is the y-intercept.

Given the equation in slope-intercept form as y = -2x + 5, it means that the graph will have a slope that has a ratio of the rise to the run as -2, while the line will intercept the y-axis at y = 5.

Therefore, the graph in the image attached below shows the equation, y = -2x + 5.

The exact value of the logarithmic expression 12 · ㏒₃ [z⁷ / (y⁵ · t²)] is equivalent by logarithm properties to -711 / 5.

In this question we must determine the exact value of a logarithmic expression by means of logarithm properties, which are described below:

Logarithm of a product

㏒ (a · b) = ㏒ a + ㏒ b

Logarithm of a division

㏒ (a / b) = ㏒ a - ㏒ b

Logarithm of a power

㏒ aⁿ = n · ㏒ a

Now we proceed to determine the exact value of the expression:

12 · ㏒₃ [z⁷ / (y⁵ · t²)]

12 · [㏒₃ z⁷ - ㏒₃ (y⁵ · t²)]

12 · (㏒₃ z⁷ - ㏒₃ y⁵ - ㏒₃ t²)

The two solutions for the system of equations:

y = x^2+ 5x - 3

y - x = 2

Are:

(-5, -7) and (1, -1)

Here we have the following system of equations:

y = x^2+ 5x - 3

y - x = 2

We can replace the first equation into the second one to get:

(x^2+ 5x - 3) - x = 2

x^2 + 4x - 3 = 2

x^2 + 4x - 3 - 2 = 0

x^2 + 4x - 5  = 0

Using the quadratic formula, we will get the solutions:

[tex]x = \frac{-4 \pm \sqrt{4^2 - 4*1*-5} }{2} \\\\x = \frac{-4 \pm 6}{2}[/tex]

The two solutions are:

x = (-4 - 6)/2 = -5

x = (-4 + 6)/2 = 1

To find the values of y, we can evaluate the linear equation:

when x = -5

y - (-5) = -2

y + 5 = -2

y = -2 - 5 = -7

So one solution is (-5, -7)

when x = 1

y - 1 = -2

y = -2 + 1 = -1

The other solution is (1, -1)

The line parallel to the given line 2x+2y=-12 is also -1.

Define slope.

Slope of a line refers to the measure of the steepness and the direction of a line.

Illustrate y= m x+ c.

y = mx + c refers to an equation of a line having a gradient of m and a y-intercept of c. This equation is often referred to as the slope-intercept form of the equation of a line.

We know that,

The general equation of a line is y=m x+ c,

where m = slope and b = y-intercept, c is a constant

Now, the equation of the given line is,

2x+2y=-12

⇒x + y=-6

Now expressing the equation in the form of y=m x+ c

So, y=-6-x

Further, on rearranging we get y= (-1) x-6

                                                   y = mx + c

So, according to the equation,on comparing we get

m=-1 and c=-6

On comparing, the slope of the given line is -1.

Since, 'The slopes of two parallel line is always equal'.

Thus, the line parallel to the given line is also -1.

The decibel level of the noise from a motorcycle with intensity 10⁻² watts per square inch (W/in²) is equal to 50 dB.

In Science, sound intensity can be defined as a measure of the power of a sound wave per unit area. This ultimately implies that, sound intensity is a quantity that is typically be used for measuring the energy of sound and its unit of measurement is Watts per square meter (W/m²) or .

Mathematically, sound intensity level or decibel level can be calculated by using this formula:

[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]

Note: The reference value of sound intensity is equal to 1.0 × 10⁻¹² watts per square inch (W/in²).

Since the intensity of the noise from this motorcycle is 10⁻² W/in², the decibel level (in dB) would be calculated as follows:

Decibel level, β = 10 × log(10⁻²/10⁻¹²)

Decibel level, β = 10 × log(10¹⁰)

Decibel level, β = 10 × 10

S.I = P(1 + rt)

Substituting the values into the simple interest formula

S.I = 1000(1 + 0.07 * t)

However, we are to calculate the time it takes to double the money

2000 = 1000(1 + 0.07 * t)

The probability that a student chosen at random studies physics and chemistry or both is  35/41 = 0.85

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes.

The system of linear equations have no solution

The system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.

In the problem, given the system of linear equations are

y = 4/5x - 3 ...eq(i)

y = 4/5x + 1 ...eq(ii)

a) Since there are two unknown variables(x, y) the number of solutions expected is 2.

b)

From equation (i)

y = 4/5x - 3

Put eq(i) into equ(ii)

4/5x - 3 = 4/5x + 1

0 = 4

There's no solution for x and y

In the calculation, there's no solution for both x and y because the variables in both equation are equal to one another and hence cancel out.
