A quantity with an initial value of 980 decays exponentially at a rate of 0.3% every 6 decades. What is the value of the quantity after 49 decades, to the nearest
hundredth?

Answers

Answer:

956.73

Step-by-step explanation:

0.3% = 0.003

1-0.003 = 0.997

49/6 = 8 r1 (use 8 because decay is not continuous)

0.997^8 = 0.97625...

0.97625... x 980 ≈ 956.73

Anyone help me solve for y.

Answers

Answer:

y = - 4

Step-by-step explanation:

Given

y = 2x + ( - 2) , that is

y = 2x - 2 ← substitute x = - 1

y = 2(- 1) - 2 = - 2 - 2 = - 4

This is confirmed by the point (- 1, - 4 ) on the graph

X = -1
So if you Plug that in to your problem it is shown as y=2(-1)+-2.
2•-1 is -2 and when added to -2 you answer is -4.
Y=-4

Compare the functions shown below: g(x) f(x) = −3x + 2 cosine function with y intercept at 0, negative 3 h(x) = 4 sin(2x + π) + 3 Using complete sentences, explain which function has the greatest y-intercept.

Answers

Answer:

3 h(x) = 4 sin(2x + π) + 3

Step-by-step explanation:

The function h(x) has a greater y-intercept

How to compare the functions?

The functions are given as:

f(x) = -3x + 2 h(x) = 4 sin(2x + π) + 3

Set x to 0,to calculate the y-intercepts

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

h(0) = 4 sin(2(0) + π) + 3 = 3

From the above computation, we have:

f(0) = 2

h(0)= 3

By comparison, we have:

h(0) > f(0)

This means that the function h(x) has a greater y-intercept

Ohh !! I’ll help you. I think your suppose to find the area of the rectangle prism? I suppose?
To find the rectangular prism, you’ll have to use this formula : LWH
L= length
W=width
H=height
Multiply those together and you will get your answer.

According to the line of best fit, if a batter struck out about 80 times, about how many hours did the batter practice?

Answers

Answer:

The batter practice for 4 hours

Step-by-step explanation:

Here, we want to use the line of best fit for an estimation

What we will do here is to identify the point 80 strikecuts on the y-axis

After getting this, we trace this right wards toward the line of best fit

Upon getting this, we trace down to the x-axis to get the number of hours indicative of the strikecuts

By doing this, we can see that the number of hours is simply 4 hours

Answers

Answer:

4(3)+0.95=X

Step-by-step explanation:

Answer:

A sixth-grade student bought three cans of tennis balls for $4 each.

The sales tax for each can was $0.95.

To Find :

The total amount the student spent.

Solution :

Price of each can including taxes :

p = $( 4 + 0.95 )

p = $4.95

So, price of 3 such cans including tax is :

P = p×3

P = $( 4.95×3 )

P = $14.85

Therefore, total amount spend by the student is $14.85 .

A .Write an equation for the trend line in slope -intercept form .

Answers

Given:

The graph of a trend line.

To find:

The equation of the trend line is slope intercept form.

Solution:

From the given graph it is clear that the equation of the trend line is passes through the points (0,25) and (5,50).

Slope of the line is:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{50-25}{5-0}[/tex]

[tex]m=\dfrac{25}{5}[/tex]

[tex]m=5[/tex]

The line passes through the point (0,25). So, the y-intercept of the line is 25.

Slope intercept form of a line is:

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

The slope intercept from of the line is:

[tex]y=(5)x+(25)[/tex]

[tex]y=5x+25[/tex]

Therefore, the equation for the trend line in slope -intercept form is [tex]y=5x+25[/tex].
