What value, written as a decimal, should lena use as the common ratio? 1.0 1.5 2.5 2.0
mariarad [96]

The Lena has no common ratio for the sequence 1.0 1.5 2.5 2.0

According to the question,

1.0  1.5  2.5  2.0

a = 1.0

r = 1.5/1 = 1.5

r = 2.5/1.5 = 1.6667

r = 2/2.5 = 0.8

common ratio is different, so given sequence is not geometric sequence.

Hence,  the Lena has no common ratio for the sequence 1.0 1.5 2.5 2.0.

If sin(2x + 7)degrees =cos(4x-7)degrees, what is the value of x?
nikklg [1K]

Answer:

x = 15

Step-by-step explanation:

cosx = sin(\frac{\pi}{2} - x)

sin x = sin y = > x = sin^{-1}(sin y) = y => x = y

sin(2x + 7)^{\circ} = cos(4x - 7)^{\circ}\\\\sin(2x + 7)^{\circ} = sin(\frac{\pi}{2} - (4x - 7))\\\\(2x + 7) = (\frac{\pi}{2}- (4x -7))\\\\2x + 7 = \frac{\pi}{2} - 4x + 7\\\\6x = \frac{\pi}{2}\\\\x = \frac{\pi}{12}

x = 15

Need answer asap and thank you
frozen [14]

Answer:

31 feet

Step-by-step explanation:

Find x by using the tangent function. Tangent is the opposite over the adjacent.

tan 52 = \frac{40}{x}\\x(tan52) = 40\\x=\frac{40}{tan 52} \\x= 31.25

The distance rounded was 31 feet.
