Identify growth or decay then describe its rate (r=%) Y=e^-0.3t

1 answer:

7 0

Y=e^-0.3t would better be written as y<span>=e^(-0.3t), because you want to emphasize that the exponent of "e" is -0.3t. Enclose the expon. within ( ), ps.

Since the expo is neg, this is expo. decay, and the rate is 0.3 per time period.

For example, if y is = to .5 right now, the next value, after 1 time period, will be
.5(.3) = .15.</span>

!!!Quick!!! Barbara can walk 3200 meters in 24 minutes. How far can she walk in 3 minutes? (In Meters)

suter [353]

Answer:

400 meters

Step-by-step explanation:

First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).

Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.

Hope this helps you out and have a wonderful day (✿◡w◡)

A plank 6m long leans against a vertical wall so that the foot of the plank is 4m away from the wall. A lizard climbs 2m up the

Lynna [10]

Answer: $\dfrac{8}{3}\ m$

Step-by-step explanation:

Given

Length of the plank is $6\ m$

Foot of the flank is $4\ m$ away from the wall

Lizard climbs 2 m up the wall

from the figure, the two triangles are similar

$\therefore \dfrac{2}{6}=\dfrac{x}{4}\\\\\Rightarrow x=4\times \dfrac{2}{6}\\\\\Rightarrow x=\dfrac{4}{3}\ m$

So, the distance from the wall is

$\Rightarrow 4-x\\\\\Rightarrow 4-\dfrac{4}{3}\\\\\Rightarrow \dfrac{8}{3}\ m$

A television and a DVD player cost a total of 1296. The cost of the television is two times the cost of the DVD player. find the

seraphim [82]

You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.

marissa [1.9K]

Answer:

About 108 times

Step-by-step explanation:

Given:

An average soccer player travels 7 miles during a game

A typical field is 104 meters long.

To find:

How many times did the average soccer play travel the length of the field?

Solution:

An average soccer player travels during the game = 7 miles

First convert 7 miles into meters, 1 mile = 1609.34 meter

7 mile = 1609.34 \times 7 = 11265.41 m

Length of field = 104 meters

To find number of times average soccer player travel the length of the field, we will divide an average soccer player travels during the game by Length of field

11265.41 m $\div$ 104 = 108.32

Therefore, about 108 times average soccer player travel the length of the field
