how do you find the area of a circle
​

Answer:

See below

Step-by-step explanation:

To find zeroes:

  0 = (-16t-4)(t-2)

      so   -16t-4 = 0      t = -1/4

         or  t-2 = 0         t = 2  

when the ball is thrown, t= 0

  put t= 0 in the equation to find the initial height

      y = ( -16t -4)(t-2)

        = ( -16(0)-4)(0-2) = (-4)(-2) = 8 ft

The rationalize of all denominators is [tex]40x^{14} y^{20} i[/tex]

We rationalize the denominator to make certain that it will become less complicated to carry out any calculation at the rational number. while we rationalize the denominator in a fraction, then we are eliminating any radical expressions inclusive of rectangular roots and dice roots from the denominator.

The distinction is that denial flat out says there may be no trouble whilst clarification is smarter, it justifies thoughts and behaviors on some different grounds in the try to convince Self and others that these minds and behaviors are not maladaptive, that they may be definitely adaptive.

The rationalize is a disavowal defense mechanism that permits an individual to address emotional conflicts, or inner or external stressors, via devising reassuring or self-serving however incorrect factors for his or her personal or others' mind, actions, or feelings, which cowl up different reasons (Perry 1990).

After simplifying the radical expression 5 √(-64)  x¹⁴  y²⁰, the result is 40 x¹⁴ y²⁰ i.

We are given the radical expression as:

5 √(-64)  x¹⁴  y²⁰

We need to simplify the radical expression and find the value of the expression.

Now, we will first simplify the term √(-64)

We know that:

√(-64) = √( - 1 × 8 × 8 )

= 8 √ -1

Using the properties of complex numbers, we get that:

√ - 1 = i

= 8 i

Putting it in the expression, we get that:

= 5 ( 8 i ) x¹⁴ y²⁰

= 40 x¹⁴ y²⁰ i

Therefore, we get that, after simplifying the radical expression 5 √(-64)  x¹⁴  y²⁰, the result is 40 x¹⁴ y²⁰ i.

q = -20

Step-by-step explanation:

The solution of the equation will be negative 20. Then the number of solutions to the equation will be one.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

7q – 20 = – 10q + 20 + 19q

Simplify the equation, then we have

7q – 20 = – 10q + 20 + 19q

– 19q + 10q + 7q = 20 + 20

– 2q = 40

q = 40 / (–2)

q = – 20

The solution of the equation will be negative 20. Then the number of solutions to the equation will be one.

The number of hours the polls open on the election day was 9 hours

From the question, we are to determine how long the polls opened on the election day

From the given information,

6,504 people vote in the advance polls for a riding prior to the election

and

A total of 10,167 people voted in that riding

Thus,

The number of people that voted on the election day = 10167 - 6504

Number of people that voted on the election day = 3663

Also, from the given information

The polling stations for the riding record an average of 407 voters per hour

Then,

Number of hours the polls open on election day = Number of people that voted on the election day ÷ Average number of voters per hour

Number of hours the polls open on election day = 3663 ÷ 407

Number of hours the polls open on election day = 9 hours

Hence, the number of hours the polls open on the election day was 9 hours

The population in the city in 2020 to the nearest 100 is 235242.65.

The population of the city was 228,000 in the year 2010.

From 2010 to 2015, the population grew by 7.7%.

The population decreases by 4.2 % from 2015 o 2020.

Initially, the population of the city is 228,000.

From 2010 to 2015,

The city's population increased by 7.7%.

7.7% of 228,000 = ( 7.7 / 100) × 228,000 = 17556

The population of the city from 2010 to 2015 = 228,000 + 17556 = 245556

From 2015 to 2020,

Now, the city's population decreases by 4.2%.

4.2% of 245556 = ( 4.2 /100) × 245556 = 10313.352.

Therefore,

The population of the city in the year 2020 = 245556 - 10313.352 = 235242.648

Therefore, the population in the year 2020 to the nearest 100 is 235242.65.

When dividing with polynomials one factor becomes the dividend and the other factor becomes the quotient. This is false.

It should be noted that a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, as well as non-negative integer exponentiation of variables

Dividing polynomials simply requires that a particular factor becomes the divisor and the other factor becomes the quotient.

The slope intercept form in math is one of the forms used to calculate the equation of a straight line, given the slope of the line and intercept it forms with the y-axis. The slope intercept form is given as, y = mx + b.

Given:

(100, 4350) and (155, 6000)

So, slope = 6000- 4350 / 155-100

slope = 1650/55

slope= 30

So, the equation is

y-6000 = 30( x- 100)

y - 6000 = 30x - 3000

y = 30x +3000

The value of y on the unit circle is y =-3/5

A circle is defined as the locus of a point such that it is equidistant from a fixed point.

The equation of a circle with center at the origin is given by x² + y² = r² where r = radius of circle

A unit circle is a circle with radius, r = 1.

So, the equation of a unit circle is x² + y² = 1

Given that the point P(-4/5, y) lies on the unit circle, and P is int he third quadrant, making y subject of the formula in the equation for unit circle, we have

y = ±√(1 - x²)

Substituting x = -4/5 into the equation, we have

y = ±√(1 - x²)

y = ±√(1 - (-4/5)²)

y = ±√(1 - 16/25)

y = ±√[(25 - 16)/25]

y = ±√[9/25]

y = ±3/5

Now, given that P is in the third quadrant, it implies that y is negative. so, y = -3/5

So, the value of y on the unit circle is y =-3/5

It follows from the fact that the rate of change, m is constant in the situation described. Hence, the equation is a linear equation.

On this note, the required equation which represents total cost, c in terms of p, m and t can be written as;

C = mt + p.

Hence, to solve the equation above for t;

Subtract p from both sides so that;
