Answer:

$\sqrt[2]{225} =15$ , $\sqrt[2]{961} =31$ , $\sqrt[2]{3969} =69$ , $\sqrt[2]{10404} =102$

Step-by-step explanation:

$\sqrt[2]{225} =\sqrt{15*15}=15$

$\sqrt[2]{961}=\sqrt{31*31} =31$

$\sqrt[2]{3969} =\sqrt{69*69} =69$

$\sqrt[2]{10404} =\sqrt{102*102}=102$

Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antid

Kisachek [45]

Answer:

$35x - \frac{9x^2}{2} + C$

Step-by-step explanation:

The antiderivative of the function is the same as the integral. To find the integral or antiderivative, reverse the process of differentiation method. Currently the function has degree 1. Through integration we increase the degree of each term by 1 and divide by the degree.

Thus 35 - 9x becomes $35x - \frac{9x^2}{2} + C$ . We add a constant C for any possible constant that was eliminated during differentiation.

tangare [24]

Answer:

14.285714285714 %

Step-by-step explanation:

suppose the weekly payment is of x dollars

Then

Previous payment : $(x/40) per hour

New payment : $(x/35) per hour

Then

The percentage increase in the hourly rate of pay is :

$=\frac{\frac{x}{35} -\frac{x}{40} }{\frac{x}{40} } \times100$

$=\frac{\frac{5x}{1400} }{\frac{x}{40} } \times100$

$=\frac{5x}{1400} \times \frac{40}{x} \times100$

$=\frac{200}{1400} \times100$

$=\frac{1}{7} \times100$

$=14.285714285714$

Adam borrowed $5,600 from the bank. The bank charges 4.2% simple interest each year.

Igoryamba

Answer:

$235.2

Step-by-step explanation:

Given data

Principal= $5,600

Rate= 4.2%

Time= 1 year

The expression for the simple interest is given as

SI= PRT/100

substitute

SI= 5600*4.2*1/100

SI= 23520/100

SI=$235.2

Hence after 1 year he will pay $235.2

Find the product of √3 and 5√3 in simplest form. Also, determine whether the

pshichka [43]

The product of √3 and 5√3 in its simplest form is 15.

<h3>What is a rational number?</h3>

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

To determine the product of √3 and 5√3

So, (√3 )(5√3)

⇒ 5 (√3 )(√3 )

⇒ 5(3)

⇒ 15

The result is rational because 15, can be expressed as a ratio of two integers can be 15/1 of two integers, a numerator 15, and denominator 1 ( which is a non-zero).

Thus, the result is rational.
