Answer:

X = 33.05

Step-by-step explanation:

\sin(x)  =   \frac{6}{11}   \\ x = 33.05

Answer:

x = 33 ( rounded to the nearest whole )

x = 33.1 ( rounded to the nearest tenth )

x = 33.06 ( rounded to the nearest hundredth )

Step-by-step explanation:

We can solve for x using trigonometry

Remember these are the "common" trig ratios

Sin = Opposite over Hypotenuse

Cos = Adjacent over Hypotenuse

Tan = Opposite over Adjacent

For angle "x" we are given it's opposite side length (6) and the hypotenuse (11)

When working with the opposite side length and hypotenuse we use trig ratio Sine.

Recall that sin = opposite over hypotenuse

Thus, sin(x)=\frac{6}{11}

We then want to isolate "x"

To do so we need to get rid of the "sin"

We can do this by multiplying each side by the inverse of sin ( sin ) ^-1

sin(x)*sin^-^1=x\\sin^-^1(\frac{6}{11}) =33.05573115

we're left with x = 33.05573115

Question 1 :<br><br> what means to make a fraction as simple as possible? we also call it reducing.
Diano4ka-milaya [45]
This means making the fraction reduced to its lowest term
example= 
make the fraction 18xz/4z simpler
the z cancels each other making it remaining 18x/4
2 can go in x as in 18
=9x/2
so the simpler form of the fraction 18xz/4z
=9x/2

If you had to pick a number 1-4 what would be the luckiest?
earnstyle [38]

I always feel drawn to the number 2 for some reason because it is in the middle between 2 and four and usually when given an option to pick a number I never pick a number that they say. Personally I just feel drawn to pick the number 2 its a nice even number and perhaps could be lucky :)

You find an interest rate of 10% compounded quarterly. Calculate how much more money you would have in your pocket if you had us
Elena-2011 [213]

Answer:

see the explanation

Step-by-step explanation:

we know that    

step 1

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

r=10\%=10/100=0.10\\n=4  

substitute in the formula above

A=P(1+\frac{0.10}{4})^{4t}  

A=P(1.025)^{4t}  

Applying property of exponents

A=P[(1.025)^{4}]^{t}  

A=P(1.1038)^{t}  

step 2

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

r=10\%=10/100=0.10  

substitute in the formula above

A=P(e)^{0.10t}  

Applying property of exponents

A=P[(e)^{0.10}]^{t}  

A=P(1.1052)^{t}  

step 3

Compare the final amount

P(1.1052)^{t} > P(1.1038)^{t}

therefore

Find the difference

P(1.1052)^{t} - P(1.1038)^{t} ----> Additional amount of money you would have in your pocket if you had used a continuously compounded account with the same interest rate and the same principal.

Need help solving. Prefer you show each step in solving.
pashok25 [27]

Answer: 25

Step-by-step explanation:

To solve for UC, you can subtract the length of CN from UN.

UN=40

CN=15

40-15=25
