For this case we have the following sequence:
 0.8
 3.2
 12.8
 51.2
 This sequence can be written as:
 0.8 = 0.2 * 4 = 0.2 * 4 ^ 1
 3.2 = 0.2 * 16 = 0.2 * 4 ^ 2
 12.8 = 0.2 * 64 = 0.2 * 4 ^ 3
 51.2 = 0.2 * 256 = 0.2 * 4 ^ 4
 Therefore, we have that the generic expression for this case is:
 an = 0.2 * 4 ^ n
 Then, the next number is then:
 a5 = 0.2 * 4 ^ 5 = 0.2 * 1024 = 204.8
 answer
 the next number in the pattern is 204.8

We need to attach a support wire to Glendale's flagpole, which is 24 feet high. The
antoniya [11.8K]

Step-by-step explanation:

this creates a right-angled triangle.

the right angle (90°) being the angle between flag pole and ground.

the angle ground-wire is 50°.

because we know that the sum of all angles in a triangle is always 180°, we know then that the angle flagpole-wire is

180 - 90 - 50 = 40°

so, we have the situation to know 1 side and all angles.

to get the other sides we use best the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and related angles are always opposite of each other.

in our case now we have

24/sin(50) = wire/sin(90) = wire/1 = wire = 31.32977494... ft

so, the rounded answer is that the wire must be

31.3 ft long

Given cos t = 1/2 tan 0 find sin (t) and sec (t)
777dan777 [17]

Answer:

Sin(t) =  \frac{\sqrt{3} }{2} } and sec(t) =2

Step-by-step explanation:

The secant function is the reciprocal function of the cosine function. Therefore, given that sec(t) = \frac{1}{cos(t)} then, if  cos(t) = \frac{1}{2} then  sec(t) =2.

On the other hand, if cos (t) = 1/2 ⇒ t = ±\frac{\pi}{3}

Then, the sin(\frac{\pi}{3}) = \frac{\sqrt{3} }{2} }

Need help on this question please
Natasha_Volkova [10]

Hello!


This question is an example of function composition.


Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).


f(x - 1) = 3(x - 1) - 5

f(x - 1) = 3x - 3 - 5

f(x - 1) = 3x - 8


Therefore, the answer is choice D, f(x - 1) = 3x - 8.
