Either table C or Table D shows a proportional relationship

Answer:

Table D

Step-by-step explanation:

1)To verify a proportional relationship. You must simply divide "y" coordinate over "x" coordinate like this: \frac{y}{x}=k. This constant K remaining the same, displays a proportional relationship between them.

Verifying C

\frac{y}{x}=\frac{1}{2}\neq\frac{3}{4}\neq \frac{5}{6}\neq\frac{7}{8}

Not Proportional

So let's check for D

\frac{y}{x}=\frac{1}{2}=\frac{3}{6}=\frac{4}{8}=\frac{5}{10}=\frac{1}{2}\Rightarrow k=\frac{1}{2}

Proportional :)

Geometrically, when there's a proportional relationship the line passes through the Origin. Check the graph for table D.

On a given dive, a platform diver’s body follows a path that can be modeled by the equation d = −4t^2 + 2t + 6, where d represen
ludmilkaskok [199]

Answer:

t = 1.5 seconds

Step-by-step explanation:

Given that d = −4t^2 + 2t + 6,

where d = distance above the water and

t = seconds.

Let assume that it's a perfect parabola

At the symmetry

t = -b/2a

Where a = -4, b = 2

t = -2/2(-4)

t = 1/4

To determine how long it will take a diver to reach the water’s surface

d = −4t^2 + 2t + 6

At water surface d =0

4t^2 - 2t - 6 = 0

Factorizing the above equation leads to

4t^2 + 4t - 6t - 6 = 0

4t(t + 1) -6(t + 1) = 0

4t - 6 =0

4t = 6

t = 6/4= 3/2 = 1.5 seconds

Since t can't be negative so we ignore the second factor.

Which step will get you closest to the solution of this equation 5×(x-2)=7
scZoUnD [109]

Answer:

Division property get you to the quick solution

Solution: 3.4

Step-by-step explanation:

5*(x - 2) = 7

Dividing both sides by 5

5*(x -2)÷5 = 7÷5

x - 2 = 1.4

Adding 2 on both sides, we

x -2 + 2 = 1.4 + 2

x = 3.4

Hope you will understand the concept.

Thank you.

Bacillus cereus is a soil-dwelling bacterium that sometimes causes food poisoning. Each cell divides to form two new cells every
Readme [11.4K]

Answer: There are 6400 bacteria that will be present after 3 hours.

Step-by-step explanation:

Since we have given that

Initial number of bacterial cells = 100

Each cell divides to form two new cells every 30 minutes.

Number of hours = 3 hrs

Number of minutes in 3 hours = 3\times 60 = 180 minutes

Number of 30 minutes in 3 hours = \dfrac{180}{30}=6

So, our equation becomes,

P(x)=ab^x\\\\P(3)=100(2)^6\\\\P(3)=6400

Hence, there are 6400 bacteria that will be present after 3 hours.
