The ladder with a length of 20 feet makes 19.4° with the ground.

Length of the ladder = 20 feet

Distance of base of the ladder from the wall = 5 feet

<h3>What is the Cosine of an angle?</h3>

The cosine of an angle is the ratio of the adjacent side(to that angle) to the hypotenuse of the right triangle.

Suppose the ladder makes 0 from the ground.

So, Cos0=\frac{5}{20}

Cos0=\frac{1}{4}

0=Cos^{-1}(\frac{1}{4})

0=Cos^{-1}0.3

0=19.4°

Thus, the ladder makes 19.4° with the ground.

Use Pythagorean theorem
a2 + b2 = c2
x2 + 5^2 = 20^2
x^2 + 25 = 400
x^2 = 375
x = 19.4 feet

Suppose f(n) = 100n and g(n) = n 2 . Compute f(n)/g(n) for n = 1, 10, 100, 1000, and 10, 000.
umka2103 [35]

Answer:

f(1)/g(1) =100

f(10)/g(10) =10

f(100)/g(100) =1

f(1,000)/g(1,000) =0.1

f(10,000)/g(10,000) =0.01

Step-by-step explanation:

Applying the values of n=1, 10, 100, 1,000, and 10,000. To the function f(n)/g(n) yields:

f(n) = 100n\\g(n) = n^2\\\\\frac{f(n)}{g(n)} =\frac{100n}{n^2}=\frac{100}{n}\\\\\frac{f(1)}{g(1)} =\frac{100}{1}=100\\\\\frac{f(10)}{g(10)} =\frac{100}{10}=10\\\\\frac{f(100)}{g(1)} =\frac{100}{100}=1\\\\\frac{f(1000)}{g(1000)} =\frac{100}{1000}=0.1\\\\\frac{f(10000)}{g(10000)} =\frac{100}{10000}=0.01\\

What is 76.78 rounded to the nearest whole number?
mars1129 [50]

Lets look at the number. 76.78. In each of the different place holders the number is higher than 5. Lets do some examples. 74 rounded to the nearest whole number is going to be 70. 76 rounded to the whole number will be 80. The .78 in your question also contributes. 


Answer: 80

80 not the nearest whole number the nearest whole number is the nex number up or down rounded so u would take .78 thats higher than .50 so u would round up so when u round up u go to 77 u don round 76 up to 80 u only round only .78 up to make 76 77
