First problem:

cos (theta)=1

Using the inverse cosine function, you get theta = 0.

Now we find tan 0 = 0

cot(theta) = 1/tan(theta) = 1/0

Division by zero is undefined, so the answer is d. undefined

Second problem:

cos (theta)=1

Use the inverse cosine function.

theta = 0°

Answer: c. 0°

Need this to graduate. Math 3- 10 points. Find the function!

Klio2033 [76]

<h2>Hello!</h2>

The answer is:

The fourth option,

$(f-g)(x)=11x$

To solve the problem, we must remember the following property of the functions:

Subtraction of functions:

We have that,

$(f-g)(x)=f(x)-g(x)$

We are given the functions:

$f(x)=4x+3$

and

$g(x)=3-7x$

So, calculating we have:

$(f-g)(x)=f(x)-g(x)$

$(f-g)(x)=(4x+3)-(3-7x)$

$(f-g)(x)=4x+3-3+7x$

$(f-g)(x)=4x+7x+3-3=11x$

Hence, the answer is the fourth option,

$(f-g)(x)=11x$

Have a nice day!

Answer:

Step-by-step explanation:

4+9+14+...+494

d=9-4=5

\[a_{n}=a_{1}+(n-1)d\] $494=4+(n-1)5\\490=(n-1)5\\n-1=98\\n=98+1=99\\S_{n}=\frac{99}{2} (4+494)\\=99*\frac{498}{2} \\=99*249\\=24,651$
