Step-by-step explanation:

${30.5}^{2} = {x}^{2} + {19.1}^{2} \\ 930.25 = {x}^{2} + 364.81 \\ {x}^{2} = 930.25 - 364.81 \\ {x}^{2} = 565.44 \\ x = \sqrt{565.44} \\ \\ x = 23.78$

Given the function f(x)=7x^3+4x-4 Find f(5)

daser333 [38]

Here,

f(x) = 7x^3 + 4x - 4

f (5) = ?

Now,

f (5) = 7*5^3 + 4*5 - 4

= 7*125 + 20 - 4

= 875 + 20 - 4

= 895 - 4

= 891

It's a Right answer...

I hope you understand...

Help with proving the following

Galina-37 [17]

Hello and Good Morning/Afternoon

Let's take this problem step-by-step:

First step

⇒ consider the fact cotθ = 1 / (tanθ)

$\frac{1+tanx}{1+cotx} =\frac{1+tanx}{1+\frac{1}{tanx} }$

Second step

⇒ form a common denominator for the fraction in the 'denominator'

$\frac{1+tanx}{1+\frac{1}{tanx} } =\frac{1+tanx}{\frac{tanx+1}{tanx} }$

Let's flip over the fraction on the denominator

$\frac{1+tanx}{\frac{tanx+1}{tanx} } =(1+tanx) * \frac{tanx}{1+tanx} =tanx$

And there you go, you have proved the statement by following these steps!

*note, I used 'x' because the equation creator didn't have 'θ' symbol

Hope that helps!

A company issues 7% bonds with a par value of $200,000 at par on January 1. The market rate on the date of issuance was 6%. The

Step2247 [10]

Answer:

The cash paid to the bondholder on July 1 is Z = $7000

Step-by-step explanation:

From the question we are told that

The percentage bond issued by the company is $n = 7$ %

The par value of the bond is $V =$ $200,000

The market rate is $r = 6$ %

So we are told that the bonds pay interest semiannually on January 1 and July

So the cash paid to the bondholder on July 1 is mathematically evaluated as

Z = $V * \frac{7}{100} * \frac{1}{2}$

substituting value

Z = $200000 * \frac{7}{100} * \frac{1}{2}$

Z = $7000
