Answer:

m = 3/2, y intercept = 3

Step-by-step explanation:

The y intercept is where it crosses the y axis. It crosses at 3

The slope is found by using two points on the line

(-2,0) and (0,3)

m= (y2-y1)/(x2-x1)

= (3-0)/(0- -2)

= 3 / +2

=3/2

Answer:

Step-by-step explanation:

1). Vertical intercept of the graph = Point at which the graph intersects the y-axis.

Therefore, vertical intercept is y = 1000.

In this situation vertical intercept means the initial dose of the drug taken = 1000 mg.

2). From the graph attached, point (x, y) represents,

x = Time 't' or duration

y = concentration of the drug after time 't'

Point (0, 1000) represents concentration = 1000 mg of the drug after t = 0 hour

Similarly, (1, 750) represents concentration = 750 mg after t = 1 hour

Therefore, fraction of drug remained = $\frac{750}{1000}$

= $\frac{3}{4}$

3). Let the equation, representing the concentration of the drug and time is,

$y=a(b)^t$

Here, a = Initial amount of the drug (at t = 0 hours)

= 1000 mg

At (t = 1 hours), concentration of the drug = 750 mg

$y=1000(b)^t$

$750=1000(b)^1$

$b=\frac{750}{1000}$

$b=\frac{3}{4}$

Therefore, equation will be,

$y=1000(\frac{3}{4})^t$

24% of 289 estimated using<br> a rate per 100

zaharov [31]

Answer:

The answer would be 40!

Step-by-step explanation:

Estimating ~ rounding

I would round 24% (20%), and 289 (300).

using the formula:

$is/of \\$ = %/100,

I'm looking for "IS"

I multiply 20 (just 20, no percent) by 200 = 4000.

Then I divide by 100 to get the "IS".

That's how I got my answer!

Hope this helps!

Gabe is planning on riding the roller coaster 25 times. If he has already ridden 36% of his 25 times, how many times has Gabe al

AVprozaik [17]

If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.
BRANLIEST? :)

yan [13]

Answer:

Step-by-step explanation:

With the initial statement, when the trees become very old, they stop flowering, it would be expected that only trees that has stopped flowering are to be considered because they are assumed to be old trees.

But with the additional information, we had to choose trees that were

no more than 240 cm tall, the choice of trees now is only those who are not more than 240 cm tall. This implies that the choice of trees to be considered now may be old or young, once they meet the required height.
