The possible dimension are :

400 = 1 x 400

400 = 2 x 200

400 = 4 x 100

400 = 5 x 80

400 = 8 x 50

400 = 10 x 40

400 = 16 x 25

400 = 20 x 20

400 = 1 x 400

400 = 2 x 200

400 = 4 x 100

400 = 5 x 80

400 = 8 x 50

400 = 10 x 40

400 = 16 x 25

400 = 20 x 20

Question

Find (f o g)(2) and (f+g)(2) when f(x)=1/x and g(x)=4x+9

Solution 1

I believe the answers are:

(f o g) (2)= 1/17 and (f+g) (2)= 17.5

(f o g) (2)= 1/17 and (f+g) (2)= 17.5

Question

the angle of the first hill of a roller coaster is 55 degrees. if the length of the track from the beginning of the ascent to the highest point is 98 feet, what is the height if the roller coaster when it reaches the top of the first hill?

Solution 1

The height of the ascent will be given by:

sinÂ Î¸=opposite/hypotenuse

Î¸=55Â°

opposite=h

hypotenuse=98 ft

thus the height will be:

sin 55=h/98

solving for h we get:

h=98Ã—sin55

h=80.28 ft

Thus the height is 80.28 ft

sinÂ Î¸=opposite/hypotenuse

Î¸=55Â°

opposite=h

hypotenuse=98 ft

thus the height will be:

sin 55=h/98

solving for h we get:

h=98Ã—sin55

h=80.28 ft

Thus the height is 80.28 ft

Question

Nina wants to put color tiles on a square. 3 color tiles fit across the top of the square. How many rows and columns of square will Nina need? How many color tiles will she use in all?

Solution 1

The area is a square.Â If she uses 3 tiles to fit length-wise, she will need 3 tiles to fit width-wise.

Total tiles needed = 3 x 3 = 9 tiles.

**Answer: 3 rows of 3 tiles. Total of 9 tiles needed.**

Total tiles needed = 3 x 3 = 9 tiles.
