Answer:

x = .23

x = 1.43

Step-by-step explanation:

1. The root of a polynomial is when the y-value equals 0. So set the equation euqal to 0:

[tex]3x^{2} -5x+1=0[/tex]

2. Solve with the quadratic formula and you get:

[tex]\frac{5+\sqrt{13} }{6}[/tex] and [tex]\frac{5-\sqrt{13} }{6}[/tex] which is x = .23 and x = 1.43.

Answer: $12.38

Step-by-step explanation:

Property taxes are charged on vehicles and Franklin has an SUV. He will therefore be charged property taxes on the SUV.

The SUV is valued at $1.

The yearly property tax is $12.38 per $1.

Franklin's property tax will therefore be $12.38 because the SUV is worth $1.

Answer:  1/16

In decimal form, this is equivalent to 0.0625

=====================================================

Explanation:

Each of the four sections are of equal area, so that means the probability of landing on any given color is 1/4.

The probability of landing on green first is 1/4, then followed by red is another 1/4. We multiply these fractions. This is valid because each event of spinning the spinner is independent of one another. None of the spins affect any others.

We then get (1/4)*(1/4) = (1*1)/(4*4) = 1/16

The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required event / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Assuming that each section of the spinner has an equal chance of being landed on, the probability of landing on the green on the first spin is 1/4.

Since each spin is independent of the others, the probability of landing on red on the second spin is also 1/4.

To find the probability of both events happening, we multiply the probabilities of each event:

P(green and red) = P(green) × P(red) = 1/4 × 1/4 = 1/16

Therefore,

The probability of Diamond landing on the green on her first spin and then red on her second spin is 1/16.

Answer:

I don’t see any graphs. Try copying android pasting images.

Step-by-step explanation:

A x function should not have two y values for the same x value. Therefore, option C is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

In the graph C we can see for x value 1 there are two y-values 2 and 3.

For the x value 2 there are two y-values 2 and 3.

Because an x function should not have two y values for the same x value.

Therefore, option C is the correct answer.

Answer:

1ft≤h≤25ft

Step-by-step explanation:

The area of a rectangle is expressed as;

Area = Length * height

A = Lh

If the area of a rectangle is at most 400 square centimeter, this is expressed as;

A ≤400

≤ means at most i.e it can not be greater than 400

Lh ≤ 400

Given L = 16

16h ≤ 400

h ≤ 400/16

h ≤ 25

Hence the possible values of the height are with the range 1ft≤h≤25ft since the dimension can not be negative

Answer:

The height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.

Step-by-step explanation:

We know that the function

y = f(x)

where y is a function of x.

Here:

Given the function of the height of the ball as a function of time is modeled by the equation

h(t) = -16t² + 90t + 5

As the height of the ball depends upon the time as the height of the ball is a function of time.

Thus, the height (h) of the ball is termed as the dependent variable and the time (t) is called the independent variable.

Answer:

Step-by-step explanation:

[tex]d=vt-\frac{at^2}{2} \\ \\ a=\frac{2(d-vt)}{t^2} \\ \\ a=\frac{2(500-300(20)}{20^2} \\ \\ a=-27.5 \frac{m}{s^2}[/tex]

The acceleration of the tram is 1 m/s^2.

To find the acceleration of the tram, we can use the following equation:

acceleration (a) = (change in velocity) / (time taken)

First, let's convert the initial velocity to m/s:

Initial velocity = 300 m/minute

To convert to m/s, we need to divide by 60 (since there are 60 seconds in a minute):

Initial velocity = 300 m/minute ÷ 60 seconds/minute = 5 m/s

Now, let's find the final velocity. The tram travels a distance of 0.5 km in 20 seconds.

Distance traveled = 0.5 km = 500 m (since 1 km = 1000 m)

Time taken = 20 seconds

Now, we can find the final velocity (v) using the formula:

v = (change in distance) / (time taken)

v = 500 m / 20 seconds = 25 m/s

Next, we can find the change in velocity:

change in velocity = final velocity - initial velocity

change in velocity = 25 m/s - 5 m/s = 20 m/s

Finally, we can calculate the acceleration:

acceleration (a) = (change in velocity) / (time taken)

acceleration (a) = 20 m/s / 20 seconds = 1 m/s^2

So, the acceleration of the tram is 1 m/s^2.

Answer: $‭13,925‬

Step-by-step explanation:

Tommy makes $200,000 per year.

He then has to pay taxes of 10% for Federal Income Tax, 4.2% for Social Security Tax, 1.75% for Medicare Tax, and 0.5% for Local Taxes.

His total taxes are therefore:

= 10% + 4.2% + 1.75% + 0.5%

= 16.45%

Taxes in dollars are:

= Monthly salary * taxes

= (200,000/12 months) * 16.45%

= $2,741.67

Monthly take home pay:

= Monthly salary - monthly tax

= 200,000 / 12 months - 2,741.67

= 16,666.67 - 2,741.67

= $‭13,925‬
