The time taken by the ball to reach the ground is 0.067 seconds

Given,

The initial velocity of the ball (speed) = 35 feet/second

The height of the ball (distance), h = -16t² + 35t + 6

We have to find the time, (t in seconds) taken by the ball to reach the ground.

Speed = distance/time

So, Time = distance/speed

Here,

Time = (-16t² + 35t + 6) / 35

We have to solve the equation first.

-16t² + 35t + 6 = 0 is in quadratic form. So, we can solve this by using quadratic formula.

Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

Here,

a = -16, b = 35, c = 6

Now,

[tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

= [tex]\frac{-35(+-)\sqrt{35^{2}-4(-16)(6) } }{2(-16)}[/tex]

= [tex]\frac{-35(+-)\sqrt{1225 +384} }{-32}[/tex]

= (-35±√1609) / -32

= (-35±40.11) / -32

Now,

Solve for:

(-35 + 40.11) / -32 = 5.11/-32 = -0.15

Solve for

(-35 - 40.11) / -32 = -75.11 / -32 = 2.35

Lets take the height as 2.35 feet.

Now,

Time = distance/speed

Time = 2.35/35 = 0.067

Therefore, the time taken by the ball to reach the ground is 0.067 seconds.

y = -x + 6

Hence, the slope of the equation by comparison with; y = mx + c is; -1.

Therefore, the slope of the required equation is same as the two lines are said to be parallel.

Ultimately, the required equation from point-slope form of an equation is;

Answer:

• score with two questions wrong = 18

• score with x questions wrong = (20 - x)

Step-by-step explanation:

The question is divided into two parts.

The first part asks us to calculate the marks that would be scored out of 20 if someone got 2 questions wrong. To do this we simply have to subtract 2 from 20 to get the score:

score = 20 - 2

         = 18

Therefore, Yasmin's score would be 18.

The second part asks us to calculate the marks that would be scored if someone got x questions wrong instead. As we did in the first part, we have to take away x from 20 in order to get the score:

score = 20 - x,

where x can be any whole number.

Therefore, Yasmin's score would be (20-x).

using the normal distribution, the warranty period of motor last at 6.24 years.

According to given question , the average life of motor = 10 years and standard deviations = 2 years .

let X be the time period in which the warranty period of motor last . X ~ N( μ, σ²) where u is mean and s is standard deviations. X ~ N( 10, 2²) ⁼ N(μ, σ²)

it is given that only 3% number of motors are replaced and 3% = 0.03

Using normal distribution , P( X≤ x)= P(( X - μ )/ σ ≤ (x- μ)/σ ) = P ( Z ≤ (x- μ ) / σ ) =0.03

Z = (X- μ) / σ => X = Z (σ) + μ

p (Z ≤ -1.88) = 0.03 so, Z-value is - 1.88..

put all the value of variables in above formula we get , -1.88 ( 2) + 10 = X => X = - 3.76 + 10

=> X = 6.24

Thus , the motor's warranty period lasted about 6.24 years.

Shelley's cup of tea is cooling down at the rate of 1.2 degree per minute.

According to the question,

We have the following information:

Shelley's cup cooled down 12 degrees in 10 minutes.

In order to find the rate of cooling down of the cup of tea, we will divide the degrees of the cooling by the total number of minutes.

So, we have the following expression:

Rate of cooling down of Shelley's cup = Total degrees the cup cooled down/total time taken

Rate of cooling down of Shelley's cup = 12/10

Rate of cooling down of Shelley's cup = 1.2 degree per minute

Hence, the rate of cooling down of Shelley's cup is 1.2 degree per minute.

The second law is the Law of Syllogism. It states that If p → r and q → r, then p → r is true.

It is to be noted that the Law of Detachment is the most often employed deductive reasoning theory.

Equations:

Recall the identities:

Now find a and b, then find their product.

Answer:

a = - 1

Step-by-step explanation:

given the zeros of a parabola x = a and x = b , then the factors are

(x - a) and (x - b) , then the equation is

y = a(x - a)(x - b) ← a is a multiplier

here the zeros are x = - 3 and x = 3 , then factors are

(x - (- 3) ) and (x - 3) , that is (x + 3) and (x - 3) and the equation is

y = a(x - 3)(x + 3)

to find a substitute any other point on the curve into the equation

using (0, 9 ) , then

9 = a(0 - 3)(0 + 3) = a(- 3)(3) = - 9a ( divide both sides by - 9 )

Answer:

  2a.  ((500x +200)x +600)x

  2b.  $1350.68

  3.  -1

Step-by-step explanation:

2. You want to know the balance in an account at the end of 3 years with deposits at the beginning of successive years being $500, $200, and $600, and with deposits having an annual growth factor of x. You want (a) an expression for the balance in terms of x, and (b) the balance when x=1+2%.

3. You want the value of p(-2) for p(x) = 5x³ +8x² -3x + 1.

$500 is deposited at the beginning of the first year. The problem statement tells us that this has been multiplied by growth factor x by the end of the year, so the balance at that point is 500x.

At the beginning of the second year, $200 is added to the account, and the entire amount is multiplied by the growth factor for the year. That makes the balance at the end of the second year be ...

  (500x +200)x

Then $600 is added, and again the account grows by a factor of x. At the end of the third year, the balance is ...

  balance = ((500x +200)x +600)x

The growth factor is given as x = 1 +r. When r = 2%, this becomes x = 1.02. Then the balance at the end of year 3 is ...

  ((500·1.02 +200)·1.02 +600)·1.02 = 1350.68

The amount in the account at the end of three years is $1350.68.

__

The value of p(x) = 5x³ +8x² -3x +1 for x=-2 is found by substituting -2 where x is found. Evaluation can be easier by rewriting the polynomial to Horner form:

  p(x) = ((5x +8)x -3)x +1

  p(-2) = ((5(-2) +8)(-2) -3)(-2) +1 = ((-2)(-2) -3)(-2) +1 = (1)(-2) +1 = -1

The value of the function for x=-2 is -1.

Additional comment

You will note that the expression in problem 2 is also written in Horner form. If it were expanded, it would be 500x³ +200x² +600x. Evaluation takes fewer steps when Horner form is used.
