If the tangent of an acute angle is 1/4, what is the cosine of that angle?
ozzi

Answer:

0.97

Step-by-step explanation:

It is known that the tangent of an angle is given by the quotient between its sine and its cosine.

tan(x)=\frac{sin(x)}{cos(x)} =\frac{1}{4} \\\frac{1}{4}cos(x)=sin(x)\\

Applying the following property:

sin^2(x) +cos^2(x) = 1\\(\frac{1}{4}cos(x))^2 +cos^2(x) = 1\\\\\frac{17}{16}cos^2(x) = 1 \\cos(x)=0.97

The cosine of that angle is 0.97.

Rodrigo applied for a $14,000 loan at an interest rate of 5.4% for 6 years. Use the monthly payment formula to complete the stat
EastWind [94]

Answer:

A= $19354.71

At the end of 6 years

Step-by-step explanation:

$14,000 loan at an interest rate of 5.4% for 6 years.

Amount to be paid at the end of the six years is

A= p(1+r/n)^(nt)

P= $14000

r= 0.054

t = 6

n = 6*12 = 72

A= 14000(1+0.054/72)^(72*6)

A= 14000(1+ 0.00075)^(432)

A= 14000(1.00075)^(432)

A= 14000(1.38247941)

A= 19354.71

A= $19354.71

Michael went to a park that was 3 3/5 miles away. It took him 4/5 of an hour to get there. What was Michael's speed?
AnnyKZ [126]

Answer:

Where d is the distance traveled, r is the rate, and t is the time. ... It took Markus half an hour to drive home from work. ... 17. Markus lives 17 miles from work. ... What was his average speed in kilometers per hour? ... per hour, we divide by 60 to find out how many hours it took. t = 20 minutes / 60 minutes per hour. = 1/3 hours.

Kathy bicycles 8km/h faster than Dennis. In my he same time it takes Dennis to bicycle 36 km, Kathy can bicycle 60 km. How fast
Sergeeva-Olga [200]

Dennis = 12 km'h

Kathy = 20 km/h

Step-by-step explanation:

  • Lets first establish  that time is the same for both Kathy and Dennis and we can therefore assign is the value of <em>t</em>
  • Kathy is cycling 8km/h faster than Dennis. Therefore if Dennis is doing <em>x </em>km/h Kathy is doing (<em>x</em>+8)km/h
  • If it takes Kathy<em> t </em>time to cycle for 60 km at (<em>x</em>+8)km/h, we can derive the time <em>t </em>as;

(<em>x</em>+8)* <em>t </em>= 60

<em>t</em> = 60/(<em>x</em>+8)

  • We can now use this time to establsish how fast Dennis is cycling. Dennis, using a speed of <em>x</em> km/h takes the same time (60/(<em>x</em>+8)) to cycle for 36 km. Therefore;

<em>x</em> * 60/(x+8) = 36

= 60x/(x+8) = 36

36 (x + 8) = 60x

36x + 288 = 60x

288 = 60x – 36x

288 = 24x

12 =<em> x </em>

Dennis is cycling at 12 km/h

Kathy is doing x + 8

= 12 + 8 = 20 km/h
