Answer:

Option A

Step-by-step explanation:

Straight lines DE and XY are parallel lines and a transverse is intersecting these lines at two distinct points.

As evident from the figure ∠Y and angle having the measure of 94° are alternate interior angles.

Since alternate interior angles are always equal, so ∠y = 94°

Option A is the answer.

Which is the graph of the given function?

Schach [20]

ANSWER

The correct choice is A.

EXPLANATION

The given cosine function is:

$f(t) = 2 \cos( - 4t)$

This function has an amplitude of 2.

Hence it must have range,

-2≤f(t)≤2

It has a period of

$\frac{\pi}{2}$

Hence the function must complete one cycle on the interval,

[0,½π],

[½π,π],

etc.

The negative sign shows a reflection in the y-axis but since the cosine function is even, the function retraces itself.

The correct choice is A

In properties of logarithms, what is log2 25?

spayn [35]

$log_a(b)=c$ $log_a(b)=c$ translates to

$a^c=b$ $a^c=b$
let's say it equals y

$log_2(25)=y$ $log_2(25)=y$
trsnaltes to
$2^y=25$ $2^y=25$
doesn't help us
we can also translate it to
$log_2(5^2)$ $log_2(5^2)$ or $2log_2(5)$ $log_2(5^2)$
