Answer:

∠5

Step-by-step explanation:

Complementary angles are angles that:

sum to 90°
make a right angle

Given this information, angles 2, 3, and 4 are already right angles. That leaves angle 5 and angle 1 to be complementary with each other, as they form a right angle.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Eunice lives in indiana, which has a sales tax of 7%. She just bought a couch whose full price was $1200 but she got 20% off bc

Tcecarenko [31]

Answer:

Total amount paid by Eunice=$1,044

Step-by-step explanation:

Step 1: Determine full price of couch

Full price of couch=$1200

Step 2: Determine tax

Tax=tax rate×full price

where;

tax rate=7%

full price=$1200

replacing;

Tax=(7/100)×1,200=$84

Tax=$84

Step 3: Calculate the sale price

Sale price=Full price-20% discount

where;

Full price=$1,200

discount=(20/100)×1,200=$240

replacing;

Sale price=(1,200-240)=960

Sale price=$960

Step 4: Total amount paid by Eunice

Total amount paid by Eunice=Sale price+tax

where;

Sale price=$960

tax=$84

replacing;

Total amount paid by Eunice=(960+84)=$1,044

Total amount paid by Eunice=$1,044

In your lab, a substance's temperature has been observed to follow the function T(x) = (x − 4)3 + 6. The turning point of the gr

Montano1993 [528]

Yo sup??

To find the turning point we have to differentiate the given function.

T(x)=(x-4)3+6

T'(x)=3

Therefore the turning point is at 3

Hope this helps.

What is the domain of the relation y = arccscx?

Stella [2.4K]

Answer:

$y=arc\csc x$

Step-by-step explanation:

The given function is $y=arc\csc x$ .

The domain refers to all values of x for which this function is defined.

Recall that: the domain of $y=arc \sin (x)$ is $-1\le x\le1$

And we know $y=arc\csc x$ is the reciprocal of $y=arc \sin (x)$ .

Therefore the complement of the domain of $y=arc \sin (x)$ which is $(-\infty,-1]\cup [1,+\infty)$ is the domain of $y=arc\csc x$
