The answers are :

a) The derivative of this function at the point (3,256) is -96.

b) The speed at which the supply bundle is falling is negative.

What is derivative ?

Derivative is the slope of the graph of function or the slope of the tangent line at a point.

A function is given which is h(t) = 400 - 16t².

Here , h(t) gives the height of the supply bundle in feet , t seconds after it is dropped from a height of 400 feet.

a)

We have to find out the derivative of the given function at a point (3,256).

h'(t) = [tex]\frac{d}{dt}[/tex] (400 - 16t²)

h'(t) = 0 - 2 × 16 × t

h'(t) = -32 t

This function at (3,256) so , value of t is 3.

h'(t) = -32 × 3

h'(t) = -96

b)

Speed = -32 t

So , the speed at which the supply bundle is falling is negative. With increase in value of t it will keep decreasing.

Therefore , the answers are :

a) The derivative of this function at the point (3,256) is -96.

b) The speed at which the supply bundle is falling is negative.

Answer:

First Game: 65 points

Second Game : 65 points

Third Game : 59 points

Step-by-step explanation:

Average = sum of values/number of values

The number of values = 3, an d average = 63

63 = x/3

63 * 3 = x

189 = x

Now 189 is the sum of points over two games.

Their first two games are worth the same, so lets call that s +s = 2s

Their 3rd game is worth 6 less points than s, so s-6

let's add up all the terms:

2s + (s - 6) = 3s - 6

Solve:

3s - 6 = 189

3s = 195

s = 65

The first two games are worth 65, and the third game is worth 65 - 6 = 59.

-Chetan K

Answer:65, 65 and 59

Step-by-step explanation:

If represented by x and y, (2x+y)/3=63

So 2x+y=189

So if x=y+6

Put the value of x into the equation

2x + y = 189

2(y + 6) + y = 189

2y + 12 + y = 189

3y = 189 - 12

3y = 177

y = 177/3

y = 59

Therefore, x = y + 6 = 59 + 6 = 65

Answer:

14

Step-by-step explanation:

$46 in total

Hats: $2.75 * 4 bags = $11

Napkins: $3.50 * 2 packs = $7

11 + 7 = 18

$46 - $18 = $28

$2.00 / 28 = 14

If cups and plates were $2.00, that means it would take 14 sets to fill the remaining $28.

Let the unknown angle be x

[tex] \sin(x) = \frac{o}{h} \\ \sin(x) = \frac{34}{41} \\ \sin(x) = 0.8292 \\ x = \sin ^{ - 1} 0.8292 \\ x = 56.02 \degree[/tex]

Answer:

y = - 8x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 8 , then

y = - 8x + c ← is the partial equation

To find c substitute (9, - 73 ) into the partial equation

- 73 = - 72 + c ⇒ c = - 73 + 72 = - 1

y = - 8x - 1 ← equation of line

Answer:

Step-by-step explanation:

The point will be 2 on the x-axis and 5 on the y axis.

Answer:

I feel the question is incomplete but there's another formula (which we can only use if the points are the intercepts on the x and y axis)

x/a + y/b = 1( a= intercept on x axis ; b = intercept on y axis )

x/2 + y /5 = 1

multipy both sides by 10

5x + 2y = 10

2y = 10- 5x

divide both sides by 2

y = 5 - 5/2x

y = -5/2 + 5(the equation of the line if the two points are the intercepts on the both axis

The first five terms of a geometric sequence are 5, 10, 20, 40, 80.

A geometric sequence is also known as Geometric Progression (GP) is a non-zero numerical series whereby each term succeeding the very first is determined by multiplying the preceding one by a fixed, non-zero value designated as the common ratio.  

It can be expressed by using the formula:

[tex]\mathbf{a_n = ar^{n-1}}[/tex]

where;

Given that;

∴

The second term of the sequence is:

[tex]\mathbf{a_2 = 5 \times 2^{2-1}}[/tex]

[tex]\mathbf{a_2 = 5 \times 2^{1}}[/tex]

[tex]\mathbf{a_2 = 10}[/tex]

The third term of the sequence is:

[tex]\mathbf{a_3 = 5 \times 2^{3-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{2}}[/tex]

[tex]\mathbf{a_2 = 20}[/tex]

The fourth term of the sequence is:

[tex]\mathbf{a_4 = 5 \times 2^{4-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{3}}[/tex]

[tex]\mathbf{a_4 = 40}[/tex]

The fifth term of the sequence is:

[tex]\mathbf{a_5 = 5 \times 2^{5-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{4}}[/tex]

Answer:

Step-by-step explanation:

To find out the sales tax rate, we divide the sales tax by the cost of the item. This will give us what percent of the cost of the item the sales tax is equal to.

So, 20.4 divided by 340 = 0.06

To convert to percent, we multiply 0.06 by 100=6. Therefore, the sales tax rate is 6%.

Check:

340 times 0.06 (the sales tax rate) is 20.4 (the sales tax).
