Answer:

The common difference d in the given sequence is -17

Step-by-step explanation:

We need to find the common difference d of the following sequence 9 -8 -25 -42 -59

We have a₁ = 9

and a₂ = -8

The formula used is: $a_n=a_1+(n-1)d$

By putting values we can find the value of d

We have n=2, a₂ = -8, a₁ = 9 and we need to find d

$a_n=a_1+(n-1)d\\a_2=a_1+(2-1)d\\-8=9+d\\d=-8-9\\d=-17$

So, the common difference d in the given sequence is -17

The length and width of a rectangle are 19.2 cm and 12.4cm respectively. Find the angle between a diagonal and the shorter side

Daniel [21]

Answer:

57.1°

Step-by-step explanation:

The sides of the rectangle are adjacent and opposite the angle, so the measure is ...

α = arctan(opposite/adjacent) = arctan(19.2/12.4) ≈ 57.1°

The angle between the diagonal and the short side is about 57.1°.

Line A passes through the coordinate points (-2/5,0) and (0,1). Which of the following lines will line A never intersect?

expeople1 [14]

Answer:

Option B

Step-by-step explanation:

Only lines which are parallel to the line which connects the given two points will neve r intersect,

parallel line has same slope

the slope of the line which connects the given two points is, 5/2

and the line is option B also has the same slope, so those two lines will never intersect each other.

A designer wants to make a circular fountain inside a square of grass as shown at the right. What is a rule for the area A of th

Dennis_Churaev [7]

Answer:

$A=4r^{2}-r^{2}\pi$

Step-by-step explanation:

1. To calculate the area of the grass you must substract the area of the square and the area of the circle.

2. The area of the square is:

$A1=L^2$

Where $L$ is one side of the square.

3. You have that:

$L=2r$

4. Therefore:

$A1=(2r)^{2} =4r^{2}$

5. The area of the circle is:

$A2=r^{2}\pi$

6. The are of the grass is:

$A=4r^{2}-r^{2}\pi$
