Function f(x) represents the population of bacteria x hours after 9 a.m. What does F(2)-F(1) represent?​

Answers

Answer 1

Answer:

f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM

Step-by-step explanation:

Here x is the number of hours after 9AM

f(2) means the count of bacteria after 2 hours of 9AM i.e. at 11AM

f(1) means the count of bacteria after 1 hour of 9AM i.e. at 10 AM

f(2) - f(1) will give us the difference between the count of bacteria between 11 AM and 10 AM

Hence,

f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM

y varies directly with x. y is 84 when x is 16. What is the constant of proportionality? (Write answer as improper fraction...Remember to reduce!)

Answers

Answer: 5 1/4

Step-by-step explanation:

We use the formula for direct proportion to solve the question since we are informed that y varies directly with x and that y is 84 when x is 16.

The formula will be:

y = kx

where,

y = 84

x = 16

We then slot the values into the formula

y = kx

84 = 16k

k = 84/16

k = 5 1/4

The constant of proportionality is 5 1/4

8. Which of the following is the 43rd term of the arithmetic sequence 3,0-3, ...?
A-117
B 120
C. -123
D. -126​

Answers

Answer:

C

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = a₂ - a₁ = 0 - 3 = - 3 , thus

a₄₃ = 3 + (42 × - 3) = 3 - 126 = - 123 → C

Answer:

C. -123.

Step-by-step explanation:

nth term = a1 + d(n - 1)

43rd term = 3 +  -3(43-1)

= 3 - 126

= -123.

Hope this helps: When we have 17 parts out of 100 (or part to whole ratio 17 : 100), we have 17%. The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.

what is the mass of an object that weighs 7 kg and 50 N?

Answers

Answer:

7kg

Step-by-step explanation:

mass: amount of matter in a substance,

SI Unit: kg

It has nothing to do with N (weight) in this case so take the kg value as the mass

Answer:

0.71 kg

Step-by-step explanation:

a common equation in physics is w = mg

we can rearrange this to m = w/g

g is the acceleration of gravity: 9.81 m/s^2

w is the weight of the given equation of the object: 7 kg

so m = 7 kg ÷ 9.81 m/s^2

this gives us: m = 0.71 kg

310= -6.2f
I’m just struggling on this question;—;

Answers

Answer:

Step-by-step explanation:

sup. so what you're going to do is divide -6.2 on both sides to get f by itself

310/-6.2= -6.2f/-6.2

f=-50

Answer:

-50.

Step-by-step explanation:

310 = -6.2f

To solve for f we divide both sides of the equation by -6.2

310 / -6.2 = -6.2f / -6.2

f = -310/-6.2 = -50.
