A ball is thrown in the air from a platform that is 64 feet above ground level with an initial vertical velocity of 32 feet per second. The height of the ball, in feet, can be represented by the function shown where t is the time, in seconds, since the ball was thrown.

h(t) = -16t2 + 32t + 64

Which of the following equations shows the function rewritten in the form that would be best used to identify the maximum height of the ball?

A.
h(t) = -16(t – 1)2 + 80

B.
h(t) = -16(t – 2)2 + 128

C.
h(t) = -16(t – 2)2 + 112

D.
h(t) = -16(t – 1)2 + 96

Answer:

  3) ? = 21

  4) ? = 6

Step-by-step explanation:

3) The given ratio is ...

  A : B = 2 : 7

You want to find ? such that ...

  2 : 7 = 6 : ?

The ratio is equivalent when both numbers are multiplied by the same value.

From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.

__

4) For this one, you need to recognize that the given number corresponds to B.

  A : B = 2 : 3

  2 : 3 = ? : 9

Again, you know that 3×3 = 9, so 3×2 = ? = 6.

Answer:

1. m = 1

2. m = 0

Step-by-step explanation:

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

m = slope

To know the slope you need only 2 points of the line.

1.-

[tex]m = \frac{4 - ( - 1)}{2 - ( - 3)} \\ m = \frac{4 + 1}{2 + 3} \\ m = \frac{5}{5} \\ m = 1[/tex]

2.-

[tex]m = \frac{3 - 3}{2 - 0} \\ m = \frac{0}{2} \\ m = 0[/tex]

Answer:

Step-by-step explanation:

a.  the question can be factored as (x-5)(x-1) so the 2 x intercepts are 5 and 1

b. yes the function has a line of symmetry every parabola does and it is at  when x is 3

x. the function has a minimum value because the equation has x^2  which is 1x^2 1 is a positive meaning that the function opens upward which means it has a minimum value

Answer:

A)

(1, 0) and (5, 0)

B)

Yes.

The equation is x = 3.

C)

Yes.

In this case, we have a minimum.

Step-by-step explanation:

We are given the function:

[tex]f(x)=x^2-6x+5[/tex]

Since the highest degree is two, we can immediately determine this to be a quadratic.

A)

The x-intercepts of a function are whenever the function equates to 0. Hence:

[tex]0=x^2-6x+5[/tex]

We can factor:

[tex](x-1)(x-5)=0[/tex]

Zero Product Property:

[tex]x-1=0\text{ or } x-5=0[/tex]

Solving yields:

[tex]x=1 \text{ and } x=5[/tex]

So, our x-intercepts are at (1, 0) and (5, 0).

B)

Since this is a quadratic, it indeed has a line of symmetry.

Recall that the line of symmetry for a quadratic equivalent to the x-coordinate of the vertex.

In the given function, a = 1, b = -6, and c= 5.

Hence, the x-coordinate of the vertex is:

[tex]\displaystyle x=-\frac{b}{2a}=-\frac{(-6)}{2(1)}=\frac{6}{2}=3[/tex]

So, the line of symmetry is x = 3.

C)

Every parabola has a minimum/maximum value.

This depends on the sign of the leading coefficient.

If the leading coefficient is positive, then we have a minimum since our parabola will be curving upwards.

And if the leading coefficient is negative, then we have a maximum since our parabola will be curving downwards.

Since our leading coefficient here is 1, hence positive, we have a minimum value.

Answer:

nth term is;

0.5n-0.5

Step-by-step explanation:

As we can see, the first term is 0

The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5

Formula for nth term of an arithmetic sequence is;

a + (n-1)d

So we have

0 + (n-1) 0.5

= 0.5n-0.5

Answer:

the present age of the old ship is 8 years

The present age of the new ship is 4 years

Step-by-step explanation:

Let the age of the older ship be x

Let the age of newer ship be y

If the sum of ages of two ship 12years old, then;

x + y = 12 .... 1

Two years ago;

Older ship age = x - 2

New ship age = y - 2

If two years ago, the age of the older ship was three times the age of the newer ship, then;

x - 2 = 3(y-2)

x-2 = 3y - 6

x = 3y - 4 ....2

Substitute equation 2 into 1;

From 1; x+ y = 12

3y-4+y = 12

4y = 12 + 4

4y = 16

y = 4

Since x+y = 12

x = 12-y

x= 12-4

x = 8

Hence the present age of the old ship is 8 years

The present age of the new ship is 4 years

Answer: 5,120

Step-by-step explanation:

Your equation is:

v(t) = 320 • 4^t

You are trying to find v(2) so:

t = 2

Plug in 2 for t:

v(2) = 320 • 4²

Solve:

v(2) = 5,120 views

Answer:

30 cubic yards

Step-by-step explanation:

You will multiply 13 by two because there is two sides of 13ft

13 x 2 = 26

Then do the same thing with 31, so 31 multiply by 2

31 x 2 = 62

After that add 62 and 26

62+26=88

Then divide 88 by 3

88÷3=29.9

after that you will round 29.9 by the nearest 10 which is 30

Answer:

264/8 = 33

33 X 4 = 132

$132

The amount fruit seller collects would be equal to $132

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  fruit seller has 264 oranges packed in bags, with 8 oranges in each bag. She sells each bag of oranges for $4.

264/8 = 33

Now for 33 bag of oranges are;

33 X 4 = 132

He fruit seller collects $132

Answer:

C. 6√55

Step-by-step explanation:

The triangle given is an isosceles triangle that is divided into two equal parts by a segment.

Thus, we can apply pythagorean theorem to find x.

x = 2 × √(24² - 9²)

x = 2 × √495

x = 2 × √(9 × 55)

x = 2 × 3√55

x = 6√55
