Answer:

610 seeds

Step-by-step explanation:

b + 5b + 10 = x

if b = 1 pack of sunflower seeds, then b = 100
with this in mind, substitute 100 in for b

100 + 5(100) + 10 = x

solve

600 + 10 = x

610 = x

The speed of a falling object increases at a constant rate as time increases since the object was dropped. Which graph

Anastaziya [24]

Answer:

Step-by-step explanation:

As the object is falling from a fixed Distance, so Speed increases as time increases.

Both speed and time are Directly proportional to each other if distance remains constant.

S = k T

When , T=0, S=0

T=1 s, S=1 m/s

T=2 s, S= 2 m/s

\frac{dS}{dT}=k=Change in speed(Average Speed), if it is Change in Velocity then it will be equal to =a (Acceleration).

the ratio of the length of an airplane wing to its width is 6 to1 . if the length of a wing is 12.5 meters ,how wide must it be

erastova [34]

If you set up a proportion, this will make sense.

$\frac{6}{1}= \frac{12.5}{x}$

Now, Cross Multiply

6x = 12.5

x = 25/12

(Need Help ASAP (Willing to give 10 points for 1 question)

True [87]

Answer:

a) -2 and 4

b) function 2

Step-by-step explanation:

a)

rate of change is rise over run: change in y / change in x.

function 1:

- i will use first 2 pairs of data

- change in y: 5 - 3 = 2

- change in x: -2 - (-1) = -1

-rate of change = 2/-1 = -2

function 2:

- same idea, but find two points on the graph!

- (0,4) and (-1,0) for example! pick easy points

- change in y is 4. chabge in x is 1

- rate of change is 4

b)

function b has greatest rate of change. 4 > -2

A new 2006 Honda head was values at $25000. It depresides at a rate of 13% a year.

CaHeK987 [17]

Answer:

1. It's value in 2009 was $16,462.575

2. It's value in 2020 will be $3,558.

Step-by-step explanation:

The equation for the value of car after t years has the following format.

$V(t) = V(0)(1-r)^{t}$

In which V(t) is the value after t years, V(0) is the initial value and r is the ratio of depreciation.

In this problem, we have that:

$V(0) = 25000, r = 0.13$

So

$V(t) = V(0)(1-r)^{t}$

$V(t) = 25000(1-0.13)^{t}$

$V(t) = 25000(0.87)^{t}$

1. What was its value in 2009

2009 is 3 years after 2006, so this is V(3)

$V(t) = 25000(0.87)^{t}$

$V(3) = 25000(0.87)^{3}$

$V(3) = 16462.575$

It's value in 2009 was $16,462.575

2.What will be its value in 2020?

2020 is 14 years after 2006, so this is V14)

$V(t) = 25000(0.87)^{t}$

$V(14) = 25000(0.87)^{14}$

$V(14) = 3558$

It's value in 2020 will be $3,558.

In the cycle-plane, what is the y-intercept of the graph of the equation y=6 (x-0.5) (x+3)

lilavasa [31]

The y-intercept of the graph of the equation y = 6 (x - 0.5) (x + 3) will be negative 9.

<h3>What is a function?</h3>

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The parabolic equation of the function is given below.

y = 6 (x - 0.5) (x + 3)

Then the y-intercept of the graph of the equation y = 6 (x - 0.5) (x + 3) will be

We know that for the y-intercept, the value of x is zero. Then we have

y = 6 (x - 0.5) (x + 3)

y = 6 (0 - 0.5)(0 + 3)

y = 6 (-0.5)(3)

y = -9

More about the function link is given below.
