Hello,

Part A:

f(2)=4*2²=16
f(1)=4*2^1=8
2-1=1
(f(2)-f(1))/(2-1)=(16-8)/1=8 ; r_1=8

f(3)=4*2^3=32
f(4)=4*2^4=64
(f(4)-f(3))/(4-3)=(64-32)/1=32 ; r_2=32

Part B:
r_2=32=4*8=4*r_1

Explainations:

(4*2^2-4*2^1)/(2-1)=4*2^1(2-1)=4*2
(4*2^4-4*2^3)/(4-3)=4*2^3*(2-1)=4*8=(4*2)*4

Select the correct answer.
iogann1982 [59]

Answer:

B. 1

Step-by-step explanation:

The 40° angle and the fixed side lengths of 10 cm and 8 cm uniquely determine the locations of Points A and B.

Thus, you can construct only one triangle using these measurements.

Jin needs 0.8 gram of carbon for an experiment. She needs 4.15 times as much water. Jins says that she needs less than 4.15 gram
natima [27]

Answer:

That is a correct statement.

Step-by-step explanation:

This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.

What is the area in square units of the shaded region
sergey [27]

Answer:

The answer to your question is the letter D. 19.5 u²

Step-by-step explanation:

Process

1.- Calculate the Area of the rectangle ABCD

Area of a rectangle = base x height

                                 = (4 + 5) x 3

                                 = 9 x 3

                                 = 27 u²

2.- Calculate the area of the large triangle

Area of a triangle = base x height/2

-Substitution

Area of a triangle = (4 + 5) x 3/2

-Simplification

Area of a triangle = 9 x 3/2

-Result

Area of a triangle = 13.5 u²

3.- Calculate the area of the small triangle

Area of the triangle = 4 x 3/2

Area of the triangle = 6 u²

4.- Sum up the area of the triangles

Shaded area = 13.5 + 6 = 19.5 u²
