Brandon throws a ball across a field. The ball's height, in feet, is modeled by the function ƒ(t) = –1∕2t2 + 2t + 6, where t represents time in seconds. How long does it take the ball to hit the ground? Question 4 options: A) 2 seconds B) 4 seconds C) 8 seconds D) 6 seconds

Answers

Answer 1

Answer:

D. 6 seconds.

Step-by-step explanation:

When the ball hits the ground f(t) = 0 , so:

-1/2t^2 + 2t + 6 = 0

Take out the -1/2:

-1/2(t^2 - 4t - 12) = 0

-1/2(t - 6)(t + 2) = 0

t = -2 , 6.  We ignore the negative zero.

So the answer is 6 seconds.

Answer 2

Answer:

6 seconds is right!

If h(x) = -2x+5/4, find h(x) = 3/4

Answers

Answer:

x = 1/4

Step-by-step explanation:

We are given the function as h(x) = - 2x + 5/4. If we have to determine h(x) = 3/4 given this function, let's substitute this value into our function and solve for 'x.' This will be our solution -

3/4 = - 2x + 5/4,

If we subtract 5/4 from either side : - 2x = - 1/2

Now divide either side by - 2 : x = 1/4

Therefore our solution is x = 1/4

Answer:

[tex]x=\frac{1}{4}[/tex]

Step-by-step explanation:

So we have the function:

[tex]h(x)=-2x+\frac{5}{4}[/tex]

And we want to find h(x)=3/4.

So, we want to find the value of x such that h(x) equates to 3/4.

So, substitute 3/4 for h(x):

[tex]\frac{3}{4}=-2x+\frac{5}{4}[/tex]

First, subtract both sides by 5/4. The right will cancel.

[tex]\frac{3}{4}-\frac{5}{4}=-2x+\frac{5}{4}-\frac{5}{4}[/tex]

Subtract on the left:

[tex]-\frac{2}{4}=-2x[/tex]

Reduce on the left:

[tex]-\frac{1}{2}=-2x[/tex]

Now, multiply both sides by -1/2. The right will again cancel:

[tex]-\frac{1}{2}(-\frac{1}{2})=-\frac{1}{2}(-2x)[/tex]

Multiply on the left:

[tex]x=\frac{1}{4}[/tex]

So, for h(x) to be 3/4, the value of x is 1/4.

And we're done!

Step-by-step explanation:

So we have the equation:

[tex]\frac{2(x+4)}{3}-8=32[/tex]

First, add 8 to both sides. The left cancels:

[tex]\frac{2(x+4)}{3}=40[/tex]

Multiply both sides by 3. The left cancels:

3w – 15
Factoring out the GCF

Answers

factors of 3: 1,3
factors of 15: 1,3,5,15
GCF: 3
3(w-5)

The factored form of 3w - 15, after factoring out the Greatest Common Factor, is 3(w - 5).

To factor out the greatest common factor (GCF) from the expression 3w - 15, we first need to determine the GCF of the two terms.

In this case, the GCF of 3w and 15 is 3. Both terms are divisible by 3.

To factor out the GCF, we divide each term by the GCF:

3w/3 - 15/3

Simplifying further, we have:

w - 5

Therefore, the factored form of 3w - 15, after factoring out the GCF, is 3(w - 5).

Factoring out the GCF is a process that involves identifying the highest common factor of all the terms in an expression and dividing each term by that factor. This helps simplify the expression and can make it easier to work with or further factorize if needed.

In this case, the GCF was 3, so we divided both terms by 3 to factor it out, resulting in the simplified expression w - 5.

Soccer ball specifications require a diameter of 8.65 inches with an allowable margin of error of 0.05 inch.
Use this information to complete these statements.

The equation that can be used to find d, the diameter of a new soccer ball, is
| ____ | = ____
The minimum possible diameter of a soccer ball is ____,
and the maximum possible diameter is ____

Answers

Answer:

Equation for new diameter: |d' - 8.65| ≤ 0.05

Minimum possible diameter = 8.60 inches

Maximum possible diameter = 8.70 inches

Step-by-step explanation:

We are told that:

Ball specifications require a diameter (d) = 8.65 inches.

Allowable margin of error = 0.05 inch

Now, since we have a value for the allowable margin of error, it means that the absolute value equation to determine the possible value or the new diameter (d') would be;

|d' - 8.65| ≤ 0.05

Minimum possible diameter = 8.65 - 0.05 = 8.60 inches

Maximum possible diameter = 8.65 + 0.05 = 8.70 inches

Suppose we flip a fair coin n times. We say that the sequence is balanced when there are equal number of heads and tails. For example, if we flip the coin 10 times and the results are HT HHT HT T HH, then this sequence balanced 2 times, i.e. at position 2 and position 8 (after the second and eighth flips). In terms of n, what is the expected number of times the sequence is balanced within n flips?

Answers

Answer:

Step-by-step explanation:

Given:

fair coin is flipped n times

sequence is balanced when there are equal number of heads and tails

To find:

In terms of n, what is the expected number of times the sequence is balanced within n flips

Solution:

Let C(n,r) be the binomial co-efficient. The sample space has [tex]2^{n}[/tex]

Suppose that n is even because there are equal number of heads and tails and the number of heads and tails is not equal when n is odd.

As the result can be either head or tail so the probability of getting head is 1/2. So the number of these sequences with n/2 head is C(n,n/2) since we choose n/2 out of n to be assigned heads.

As every string sequence is equal chance of occurring so the probability is

C(n,n/2) / [tex]2^{n}[/tex]
