number 3 says,"If u and v are the measures of complementary angles such that sin u =2/5 and tan v =(square root of 21) 21/2, lab
vodomira [7]

Answer and Explanation:

Using trig ratios, we can express the given values of sin u and tan v as shown below

\begin{gathered} \sin u=\frac{opposite\text{ of angle u}}{\text{hypotenuse}}=\frac{2}{5} \\ \tan v=\frac{opposite\text{ of angle v}}{\text{hypotenuse}}=\sqrt[]{21} \end{gathered}

So we can go ahead and label the sides of the triangle as shown below;

We can find the value of u as shown below;

\begin{gathered} \sin u=\frac{2}{5} \\ u=\sin ^{-1}(\frac{2}{5}) \\ u=23.6^{\circ} \end{gathered}

We can find v as shown below;

\begin{gathered} u+v+90=180\text{   (sum of angles in a triangle)} \\ v+23.6+90=180 \\ v=180-113.6 \\ v=66.4^{\circ} \end{gathered}

You put $1000 in a savings account which earns compound interest at a rate of 0.1% per month. If you don't make any deposits or
Andre45 [30]
Amount in compound interest = p(1 + r)^n where p is the initial deposit, r = rate and n = period.
Here, Amount after 36 months = 1000(1 + 0.1/100)^36 = 1000(1 + 0.001)^36 = 1000(1.001)^36 = 1000(1.036637) = $1,036.64

Last question of the day with 25 points.
pshichka [43]

Answer:

244 degrees

Step-by-step explanation:

Since one angle APE is 90 degrees, that means line segments AD and BE are perpendicular bisectors.

Since both segments go through the center, that means all the angles are central angles.

Since angle APE is 90 degrees, that also means that angle EPD is 90 degrees.

33k -9 = 90

33k = 99

k = 3

Since we know k we can substitute it to find angle CPD.

20 k + 4 = 20*3 + 4= 60+4= 64 degrees.

Central angles equal angles of arcs, so we can and angles APE, EPD, and DPC to find the measure of major arc CAD.

64+ 90 +90 = 244 degrees

The faces of a number cube are labeled 1 through 6. If the number cube is rolled 72 times, which is closest to the number of tim
Inessa [10]

18 times

Since there only two numbers greater than 4 (5 & 6), you subtract 2 from 6.

6 - 2 = 4

Then, you divide that from 72.

72 \div 4 = 18

So, the number of times I would expect the outcome to be greater than 4 is 18.
