Reflection. Can anyone figure this out?

Answer:

z = -ln│5eᵗ + C│

Step-by-step explanation:

dz/dt + 5eᵗ⁺ᶻ = 0

dz/dt = -5eᵗ⁺ᶻ

dz/dt = -5eᵗeᶻ

-e⁻ᶻ dz = 5eᵗ dt

e⁻ᶻ = 5eᵗ + C

-z = ln│5eᵗ + C│

z = -ln│5eᵗ + C│

Answer:

Using the slope formula with points (0,-1) and (-4,4)

Step-by-step explanation:

Step 1: find the points, (0,-1) and (-4,4)

Step 2: Insert plot points into Slope formula: (tip: M means slope)

m(slope)= [tex]\frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]   ->   m(slope)=[tex]\frac{4-(-1)}{-4-0}[/tex]    

Step 3: Solve:

m(slope)=[tex]\frac{5}{-4}[/tex]

Answer:

Slope is [tex]\frac{5}{-4}[/tex]  

or m = [tex]\frac{5}{-4}[/tex]

OR (if your teacher wants the answer in decimal form rounded to the nearest 10th.) m = -1.3

Answer:

Step-by-step explanation:

Let the number of yards gained be positive

Let the number of yards lost be negative

Since the total that must be gained in the next four games is 10, hence the total is +10

If The Tigers lose 24 yards, gain 4 yards, and lose 10 yards in the first three rounds with x being the number of yards in the fourth round, this is expressed as;

-24 + 4 - 10 + x = 10

-20 - 10 + x = 10

-30 + x = -10

x = -10 + 30

x = 20

Hence they need 20 yards in the last round to keep possession

Answer:

2nd Graph

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

When we apply the Vertical Line Test to the 1st graph, it does not pass (x = 1). Therefore, the 1st graph is not a function.

When we apply the Vertical Line Test to the 2nd graph, it does pass. Therefore, the 2nd graph is a function.

When we apply the Vertical Line Test to the 3rd graph, it does not pass (x = 2). Therefore, the 1st graph is not a function.

When we apply the Vertical Line Test to the 4th graph, it does not pass (x = -3). Therefore, the 4th graph is not a function.

Answer:

2nd graph is correct

Answer:

5 mph

Step-by-sep explanation:

To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.

Unit rate/speed = distance travelled/time = y/x.

Speed of Driver 1/unit rate:

The graph shows 1.5 miles (y) is travelled in 2 minutes (x).

Convert the 2 minutes to hour, you will have:

[tex] \frac{2}{60} = \frac{1}{30} hr [/tex]

Speed in mph = [tex] \frac{y}{x} = \frac{1.5}{\frac{1}{30}} = 1.5*\frac{30}{1} = 45 [/tex]

Speed of Driver 1 in mph = 45 mph

Speed of Driver 2/unit rate:

The table shows 2.5 miles (y) is travelled in 3 minutes (x).

Convert the 3 minutes to hour, you will have:

[tex] \frac{3}{60} = \frac{1}{20} hr [/tex]

Speed in mph = [tex] \frac{y}{x} = \frac{2.5}{\frac{1}{20}} = 2.5*\frac{20}{1} = 50 [/tex]

Speed of Driver 2 in mph = 50 mph

Difference between the speed of the two drivers = 50 - 45 = 5 mph

KJI = KJY + YJI

Thus ;

[tex]168 =( 8x - 4) + (36x - 4)[/tex]

[tex]168 = 8x - 4 + 36x - 4[/tex]

Collect like terms

[tex]168 = 44x - 8[/tex]

Add sides 8

[tex]168 + 8 = 44x - 8 + 8[/tex]

[tex]176 = 44x[/tex]

Divide sides by 44

[tex] \frac{176}{44} = \frac{44}{44} x \\ [/tex]

[tex] \frac{16 \times 11}{4 \times 11} = x \\ [/tex]

[tex]4 = x[/tex]

[tex]x = 4[/tex]

So ;

[tex]YJI = 36x - 4[/tex]

[tex]YJI = 36(4) - 4[/tex]

[tex]YJI = 144 - 4[/tex]

[tex]YJI = 140°[/tex]

Done...

Step-by-step explanation:

Answer: 19/25.

Step-by-step explanation:

Given data:

Large marbles = 14

Small marbles = 11.

8 large marbles = green.

5 of small marbles = white.

Solution:

If 8 of large marbles are green, therefore the remaining 6 are white.

Likewise for the small marbles the remaining 6 are green marbles.

Total number of marbles = 14 + 11

= 25.

P(small or green) = P(small) + P (green) – P (Both)

= 11/25 + 14/25 – 6/11

= 19/25

Answer:

Answer is 0.7536

Step-by-step explanation:

Large Marbles = 14   Small Marbles = 11

Green LM = 8            Green SM = 6

White LM = 6             White SM = 5

QUESTION:

If a marble is randomly selected from the box, what is the probability that it is small or it is green?

Note the use of "or" and not "and".

SOLUTION:

In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!

The formula for this probability is hence

P(A or B) = P(A) + P(B) - P(A and B)

Let A = The event that the selected marble is small

     B = The event that the selected marble is green

Total number of marbles = 14 + 11 = 25

P(A or B) = 11/25  +  (8+6)/25  -  [P(A) × P(B)]

P(A or B) = 11/25  +  14/25  -  [11/25 × 14/25]

               = 0.44  +  0.56  -  0.2464   =  1 - 0.2464  = 0.7536
