I need help with arithmetic and geometric sequences

Mathematics
1 answer:
Drupady [299]3 years ago
7 0

So basically an arithmetic sequence has a common difference, a number which is either added or subtracted at a constant rate (only that number). A geometric sequence is the ratio between two numbers, meaning they are either multiplied or divided by the same number. The sequence would be neither if it follows none of these patterns. So by this logic:

14. Arithmetic, 15. Geometric, 16. Neither, 17. Geometric

A square patio has an area of 135 square feet. How long is each side of the patio to the nearest tenth?
Kryger [21]
11.6 because the square root of 135 is 11.61885.... and when you check it is approximately 135 because 11.6 *11.6 = 134.56, which can be rounded to 135

Factor completely 5ab(x + 6) − 4(x + 6).
konstantin123 [22]
It seems like you've begun to apply the grouping method.

Because the two binomials in the parentheses are the same, we can rewrite this as

(5ab-4)(x+6)

(x+6) cannot be further factored. (5ab-4) cannot be further factored either.

Final answer: (5ab-4)(x+6)

Pls help this is probably super easy but not for me
san4es73 [151]

Answer:

A.    29 feet

Step-by-step explanation:

Use cos to find the hypotenuse

cos  = adj/hp

0.64 = 20/hyp

hyp = 20/0.64

hyp = 31.25

---------------------------

Use Pythagorean Theorem to find the height of tree above eyes

a² + b² = c²

a² + 20² = 31.25²

a² = 31.25² - 20²

a² = 576.5625

a = 24  (to the nearest foot)

-------------------------------

Finally add in the eye height

h = 24 + 5

h = 29 feet

Solve the system of equations. y = -6x + 9 y = -3x + 3
abruzzese [7]

- 6x + 9 =  - 3x + 3 \\ 3x = 6 \\ x = 2

Substitute x = 2 into y = - 6x + 9
y =  - 6(2) + 9  \\ y =  - 12 + 9 \\ y =  - 3

Answer : x = 2, y = - 3

Hope this helps. - M
