Which angles below are complementary?
tigry1 [53]

9514 1404 393

Answer:

  ∠KXN and ∠QXT

Step-by-step explanation:

The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.

Here, we'll refer to angle aXb as "ab".

  NP = 95 -35 = 60

  PQ = 35 -20 = 15  . . .  not complementary to NP

__

  KN = 165 -95 = 70

  QT = 20 -0 = 20  . . .  complementary to KN   ⇒ your answer

__

  JK = 180 -165 = 15

  PQ = 35 -20 = 15  . . . not complementary to JK

__

  JK = 15

  NK = KN = 70  . . .  not complementary to JK

An initial of the $100 is now valuated at $150. The annual interest rate is 5%, compounded continuously. The equation 100e^0.05=
tangare [24]

Answer:

8 years approximately

The problem (I'm assuming is):

Solve 100e^{0.05t}=150.

I put a t in the problem where I suspected it in went.

Step-by-step explanation:

100e^{0.05t}=150

Divide both sides by 100:

e^{0.05t}=\frac{150}{100}

e^{0.05t}=1.5

Rewrite in logarithm form.

\ln(1.5)=0.05t

Divide both sides by 0.05:

\frac{\ln(1.5)}{0.05}=t

Put left hand side into calculator:

8.109 \approx t

t \approx 8.109

So about 8 years if I wrote down the equation correctly.
