The height, h, of an object that is thrown upwards into the air can be represented as h = 0.5at2 + v0t + h0, where a represents the acceleration due to gravity (– 32 ft/s)
2), v0 represents the initial velocity, in feet per second, h0 represents the initial height of the object, in feet, and t represents time, in seconds.

Part A:
A ball thrown upwards from the top of a 64–ft high building with an initial velocity of 48
ft/s.Write an equation that could be used to determine the time, t, in seconds, for the ball to reach the ground. Assume ground level is at a height of 0 ft.

Part B:
Determine the time, t, in seconds, that takes the ball to reach the ground and explain how you determined your answer.

Answer:

GF = 16.25

Step-by-step explanation:

If G is the circumcenter of triangle ABC, AG = 6x + 1, GC = 9x – 11, and BC = 38, find GF.

Step 1

We find x

AG = GC

6x + 1 =9x - 11

Collect like terms

1 + 11 = 9x - 6x

12 = 3x

x = 12/3

x = 4

Step 2

We solve for AG

GC = 9x + 11

GC = 9(4) + 11

GC = 36 + 11

GC = 25

Step 3

Solving for GF, using Pythagoras Theorem

GF² + BG² = GC²

GF² = GC² - BG²

GF = √GC² - BG²

GF = √25² - 19²

GF = √264

GF = 16.248076809

GF = 16.25

Answer:

201.06 square feet.

Step-by-step explanation:

=> The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.

=> The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.

=> Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet

Answer:

A. 49.79 = 1.19 + 0.25t

Step-by-step explanation:

One-time entrance fee to be paid by Haley as initial fee = $1.19

Going through the fun house each time would attract an additional fee of $0.25 each time they go through the fun house.

If Haley has $49.79, the number of times (t) Haley can go through can be expressed as:

Total amount Haley has = initial fee/entrance fee + additional fee per each time Haley goes through the fun house

The equation would be:

49.79 = 1.19 + 0.25t

Step-by-step explanation:

[tex]y^{2}=5*6+5\\ y^{2}= 5*11\\\sqrt{55}[/tex]

Answer:

Step-by-step explanation:

The zero (root) of a function is any value of the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x-axis.

~~~~~~~~~

f(x) = x³ + 3x² - x - 3

f(-3) = ( - 3 )³ + 3( - 3 )² - ( - 3 ) - 3 = 0

f(-1) = ( - 1 )³ + 3( - 1 )² - ( - 1 ) - 3 = 0

f(1) = ( 1 )² + 3( 1 )² - ( 1 ) - 3 = 0

Answer:

The zeroes of the function are x = -3, x = -1, and x = 1.

Step-by-step explanation:

We are given a polynomial and asked to find the zeroes of the polynomial. Our given polynomial is:

[tex]x^3 + 3x^2 - x - 3[/tex]

The zeroes of a polynomial are the solutions or roots of the function. This is where if the line were graphed, the line would intersect the x-axis at those points (sometimes there will only be one).

This is a cubic polynomial. We can use a factoring technique referred to as grouping, which is most effective when factoring a trinomial with the only satisfaction met is: a > 1.

However, it can also be used when a > 1 is not true.

We can work with an example polynomial first and then work through solving the given polynomial.

An example polynomial would be:

[tex]10x^2 + 8x - 9 = 0[/tex]

In grouping, our main goal is to factor as quickly as possible. If you examine the polynomial, there is no common factor between 10x², 8x, or -9, so we cannot take out a GCF and need to use another factoring technique.

Since a > 1, we can instantly jump to using the grouping factoring technique.

Please note that the parent function for a quadratic is [tex]ax^2 + bx + c = 0[/tex].

To group:

Let's use grouping to solve [tex]x^3 + 3x^2 - x - 3[/tex].

Because we already have four terms, we can skip steps one through three and go straight to step four.

[tex](x^3 + 3x^2)(-x - 3)[/tex]

Now, we need to take the GCF of both parentheses sets. Let's do this with our first set of terms.

Then, we can also do this with our second set of terms.

Because our remaining terms for both sets match, we have grouped our polynomial correctly. Now, let's combine our GCFs into one term and list our common term as the second term.

[tex](x^2-1)(x+3)[/tex]

Now, we can break apart x² - 1 into more factors.

This is the difference of two squares. The formula for the difference of two squares is [tex](a^2-b^2)=(a+b)(a-b)[/tex]

Our perfect squares are every integer in the spectrum of numbers, so 1 is a perfect square. Therefore, x² becomes x and 1 becomes ±1.

Our new terms would therefore be [tex](x+1)(x-1)(x+3)[/tex].

Finally, to find zeroes of a function, x needs to equal something. Therefore, we can set our terms equal to zero and solve for x.

Term 1 (x + 1)

[tex]x + 1 = 0\\\\x + 1 - 1 = 0 - 1\\\\\boxed{x = -1}[/tex]

Term 2 (x - 1)

[tex]x - 1 = 0\\\\x - 1 + 1 = 0 + 1\\\\\boxed{x = 1}[/tex]

Term 3 (x + 3)

[tex]x + 3 = 0\\\\x + 3 - 3 = 0 - 3\\\\\boxed{x = -3}[/tex]

Therefore, our zeroes are listed above. To finalize our answer, we want to list them in increasing order, so this will be most negative to most positive. Therefore, our final answer is x = -3, -1, 1.

Answer:

A: 96 B:192 C:288

Step-by-step explanation:

3+2+1=6

Divide 576 by 6 to get 1/6, you will get 96.

so 96 is the area of the dining room.

Multiply 2 times 96, since that would be 2/6.

That would be 192.

So 192 would be the area of the kitchen.

Here's a trick: all you need to do is add 96 and 192 now (or multiply 96 by 3), because that is half of the areas, 3/6.

So 96 times 3 is 288.

The living room is 288.

To check our work, we can add 288 by 96 by 192.

We would end up with 576, which was our original number.

So 288:192:96.
