Answer:

m∠WZX = 41°

Step-by-step explanation:

diagonals bisect angles and opposite angles are congruent

therefore, ∠WXY ≅ ∠WZY

∠WZY must equal [360 - 2(68)] ÷ 2 which equals 112°

If ∠WXZ = 71° then so does ∠XZY

Which means that ∠WZX must equal 112-71 which is 41°

<h3>Answer:  41 degrees</h3>

===================================================

Explanation:

Refer to the diagram below. I've marked up the figure with various angles to point out the angles we'll be working with.

  • angle XYZ = 68 in green
  • angle WXZ = 71 in red
  • angle WZX = unknown, in blue

To make things a bit simpler in terms of notation, and to match up colors with variable letters, I'm going to use the following

  • R = red angle
  • G = green angle
  • B = blue angle

Notice how the two red angles I've marked up are alternate interior angles. This works because WX is parallel to ZY. Also notice that the red and blue angles combine to form the angle WZY, which is adjacent to angle XYZ in green.

For any parallelogram, the adjacent angles always add to 180.

(angle WZY) + (angle XYZ) = 180

(blueAngle+redAngle) + (greenAngle) = 180

(B+R) + (G) = 180

(B+71) + (68) = 180

B+139 = 180

B = 180-139

B = 41

The blue angle is 41 degrees, which means angle WZX is 41 degrees

Side note: Your steps and answer to problem 11 are correct. Nice work.

Which of the functions below have period 2pi? Check all that apply. A. y = tan x B. y = sec x C. y = cot x D. y = csc x
Colt1911 [192]

Answer:

Option B and D are correct that is y=secx and  y=cscx  respectively.

Step-by-step explanation:

We have been given four functions:

CaseA:

y=tanx

\text{Period oftanx is} \pi

Hence, A is correct.

CaseB:

y=secx

\text{Period of secx is} 2\pi

Hence, B is correct.

CaseC:

y=cotx

\text{Period of cotx is} \pi

Hence, C is not correct.

CaseD:

y=cscx

\text{Period of cscx is} 2\pi

Hence, D is correct.

Ricky is taking out a personal loan for $12,000 to remodel his kitchen. He would like the lowest monthly payment possible, even
pochemuha

Answer : The correct Option is A.

Step-by-step Explanation :

To solve this we are going to use the monthly payment formula:

\text{Payment = }\frac{Rate\times Principal}{1-(1+Rate)^{-n}}}

where, Principal is the amount of the loan

            n  is the number of periods.

  • Option A. 13% interest for 36 months compounded monthly

Ricky is taking out a personal loan for $12,000 and term of the loan is 36 months ⇒ n = 36. To find the rate per period, we first need to convert the interest rate to decimal form ⇒ Rate = 0.13.

Now since the bank is charging him the interest rate for the 36 months, we just need to divide the interest rate (in decimal form) by the number of months (36) to find the rate per period

\implies\text{Rate per period = }\frac{0.13}{36}

So, putting all these values in the formula, We get monthly payment of loan A = $356.07

  • Option B : 12% interest for 60 months compounded monthly

interest rate in decimal form = 0.12

By replacing the values in formula the monthly payment of loan B is $212.44

  • Option C and Option D are obviously denied as the financial charge is not effected by the monthly payments so ricky will not be thinking about the financial charge.

Now, Monthly payments of loan B are significantly low than that of monthly payments of loan A.

So, we can conclude that the correct answer is  a. More payments with the 60 month loan will give him the lowest monthly payment.

Let me know the answer plz
Cloud [144]

Answer: Option G

a_6 = -2048

Step-by-step explanation:

The geometric series have the following form:

a_n = a_1 (r) ^ {n-1}

Where a_1 is the first term of the sequence and r is the common radius.

In this case we know that

a_1 = -2\\\\r = 4

So:

a_n = -2(4) ^ {n-1}

To find the sixth term a_6, substitute n = 6 in the equation.

a_6 = -2 (4) ^ {6-1}\\\\a_6 = -2 (4) ^ 5\\\\a_6 = -2048
