What is the slope of the line?

Answers

Answer:

2/3

Step-by-step explanation:

Step 1

(1,2) (4,4)

First we are going to pick two point on the line.

Step 2

(y2-y1) / (x2-x1)

(4-2) / (4-1)

in the first set we label x as x1 and y as y1, then we do the same with the other set but with x turning into x2 and y turning into y2. We then plug them into the equation.

Step  3

(2)/(3)

or

2/3

Now we solve what is in the parentheses (4-2) is 2, and (4-1) is 3. We then take away the parentheses and have 2/3. keep 2/3 as a fraction, do not change it to a decimal.

The answer would be 2/3

You work as a lab assistant. Each morning you are responsible for grouping the correct number of test tubes for each experiment that will be conducted that day. Today 40 test tubes will be used for 12 experiments. The first two experiments will require 4 test tubes each. Six of the experiments will require 3 test tubes each, and 2 of the experiments will require 2 test tubes each. Each of the two remaining experiments will use exactly the same number of test tubes.


Which calculation is appropriate to perform first when determining the number of test tubes that will be used for each of the two remaining experiments?

A) 10/2

B) 40 − 30

C) 40 − 12

D) 2(4) + 6(3) + 2(2)

Answers

Answer:  D

Step-by-step explanation:

In total 40 test tubes are required for 12 experiments.

The first two experiments will require 4 test tubes for each.

Hence, there will be a requirement of  = 8 test tubes.

Six experiments require 3 test tubes each.

Hence, these 6 experiments will take  18 test tubes.

Other 2 experiments will take 2 test tubes.

Here,  = 4 test tubes will be required.

Till now a total of (8 + 18 + 4) = 30 test tubes have been used.

The remaining number of test tubes is (40 - 30) = 10.

The remaining experiments require  test tubes.

The first calculation to perform is 2(4) + 6(3) - 2(2).

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.


0 ≤ y ≤ 80, −0.6875

0 ≤ y ≤ 80, −1.45

0 ≤ x ≤ 55, −1.45

0 ≤ x ≤ 55, −0.6875

Answers

Answer: the answer is C
Hope It Helps

The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.

What is the range and domain of a function?

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

The domain of a function is the set of input values that the function defines.

The function goes from x = 0 to x = 55 thus  0 ≤ x ≤ 55 will be the domain.

The average slope for (0,80) and (55,0)

⇒ (0 - 80)/(55 - 0) = -1.45

Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

Find the value of x in the triangle below.

Answers

Answer:

x = 50°

Step-by-step explanation:

Sum of Angles in a Triangle: 180°

All angles in a triangle must add up to 180°.

Step 1: Set up equation

x + 70° + 60° = 180°

Step 2: Solve for x

Combine like terms: x + 130° = 180°Subtract 130 on both sides: x = 50°

Answer:

50°

Step-by-step explanation:

Step 1:

x + 70° + 60° = 180°       Sum of a Δ

Step 2:

x + 130° = 180°         Combine Like Terms

Step 3:

x = 180° - 130°       Subtract 130° on both sides

Answer:

x = 50°
