Answer:

m = - 4/5

Step-by-step explanation:

y=mx+B

this is when you subtract 4x from both sides.

5y=-4x+2

now divide by each term and simplify

y=-4x/5 + 2/5

rewrite the slope-intercept form

y=-4/5 X + 2/5

(the X isn't apart of the 4 now its apart of the 4/5)

So since in y+mx+b (M being the slope)

in y=-4/5x+2/5 The (M or slope) is -4/5

So your answer is -4/5

(I just took the test)

Chase consumes an energy drink that contains caffeine. After consuming the energy drink, the amount of caffeine in Chase's body

PIT_PIT [208]

Answer:

(a) The 5-hour decay factor is 0.5042.

(b) The 1-hour decay factor is 0.8720.

Step-by-step explanation:

The amount of caffeine in Chase's body decreases exponentially.

The 10-hour decay factor for the number of mg of caffeine is 0.2542.

The 1-hour decay factor is:

$1-hour\ decay\ factor=(0.2542)^{1/10}=0.8720$

(a)

Compute the 5-hour decay factor as follows:

$5-hour\ decay\ factor=(0.8720)^{5}\\=0.504176\\\approx0.5042$

Thus, the 5-hour decay factor is 0.5042.

(b)

The 1-hour decay factor is:

$1-hour\ decay\ factor=(0.2542)^{1/10}=0.8720$

Thus, the 1-hour decay factor is 0.8720.

(c)

The equation to compute the amount of caffeine in Chase's body is:

A = Initial amount × (0.8720)ⁿ

It is provided that initially Chase had 171 mg of caffeine, 1.39 hours after consuming the drink.

Compute the amount of caffeine in Chase's body 2.39 hours after consuming the drink as follows:

$A = Initial\ amount \times (0.8720)^{2.39} \\=[Initial\ amount \times (0.8720)^{1.39}] \times(0.8720)\\=171\times 0.8720\\=149.112$

Thus, the amount of caffeine in Chase's body 2.39 hours after consuming the drink is 149.112 mg.

Please help! Find the missing

Veronika [31]

Answer:

x = 13

Step-by-step explanation:

Here, we want to get the missing side

from what we have, the triangle is a right angled triangle

In this kind of triangle, the Pythagoras’ theorem works

The square of the side facing the right angle ( marked x here) is equal to the sum of the squares of the two other sides

We have this as;

x^2 = 5^2 + 12^2

x^2 = 25 + 144

x^2 = 169

x = √169

x = 13

COULD SOMEONE WRITE FORMAT THEN WRITE EQUIVALENT FRACTION AND MIXED NUMBER 11.09 21.06 0.06 0.50 6.15 AND 7.41

Igoryamba

I think you mean write in word format so yea

11.09
"Eleven and 9 hundredths"
To convert decimals to fractions first put the decimal over 1, multiply by ten for every number after the decimal point and simplify.

(11.09/1)(10)(10) *Because there are 2 numbers after the . 0 and 9*

1109/100
This will be the most simplified you can get it!
As a mixed number:
11 9/100

Follow these steps for the rest!

21.06
"twenty one and six thousandths"
1053/50
21 3/50

0.06
"six thousandths" or
"zero and six thousandths"
3/50

0.50
"fifty thousandths" or "five tenths" since 0.50=0.5
1/2

6.15
"six and fifteen thousandths"
123/20
6 3/20

7.41
"seven and fourty one thousandths"
741/100
7 41/100
