Farfalla kites owns 3 factories around the globe. In one year, the original factory can make 600 kites, and each of the other fa

statuscvo [17]

Farfalla produces 2,400 kites every year.

The number of factories Farfalla owns around the globe = 3;

The number of kites produced by original factory every year = 600;

The number of kites produced by each of other 2 factories every year = 900;

Then the total kites produced by both other factories will be = 2 × 900 = 1800;

Now, the number of kites Farfalla produces every year is = 600 + 1800 = 2400;

The vector v=(7,1) lies entirely in quadrant 1. Give possible coordinates for the initial point and terminal point of the vector

slamgirl [31]

Answer:

A possible initial point is (1,4) and a possible terminal point is (8,5)

Step-by-step explanation:

The given vector is $\vec{v}=(7,1)$ .

We can rewrite this vector as:

$\vec{v}=\binom{7}{1}$

The x-components is 7 and the y-component is 1.

We can choose initial point (a,b) and terminal point (c,d) in the first quadrant such that $c-a=7$ and $d-b=1$

If a=1, and b= 4, then:

$c-1=7$ and $d-4=1$

This implies that:

$c=7+1=8$ and $d=1+4=5$

Therefore a possible initial point is (1,4) and a possible terminal point is (8,5)

Which expression is equivalent to (4^5/4 4^1/4/4^1/2) ^1/2

Lilit [14]

The expression is equivalent to 2 , Option C is the correct answer.

<h3>What is an Expression ?</h3>

An expression is a mathematical statement consisting of variables , constants and mathematical operators.

The expression given in the question is

$\rm( {\dfrac{4^{5/4} * 4^{1/4}}{4^{1/2}}})^{1/2}$

By exponent rule

$\rm a^m * a^n = a^{m+n}\\\\a^m \div a^n = a^{m-n}$

Here so ,

$\rm 4^{(\dfrac{5}{4} +\dfrac{1}{4} -\dfrac{1}{2})^{1/2}$

$\rm 4^{(\dfrac{6}{4} -\dfrac{1}{2})^{1/2}\\\\ \\\\\\\\\\\\\\\\\\\\\\\\\\\\$

$4^{(\dfrac{6-2}{4} )^{1/2}\\$

$4^{1/2}\\\\(2^2)^{1/2}\\\\2$

Therefore the expression is equivalent to 2 , Option C is the correct answer.
