Answer:

#1) <u>14</u><u> </u><u>3</u><u>/</u><u>5</u>

Step-by-step explanation:

#1) 147.6 = 147+0.6 = 147+6/10

147.6 = 147+0.6 = 147+6/10gcd(6,10) = 2

147.6 = 147+0.6 = 147+6/10gcd(6,10) = 2147.6 = 147+(6/2)/(10/2) = 147+3/5 = 738/5

#2) 102 = 102/1 = 1020/10

#3) 75 3/5

75.6 = 75+0.6 = 75+6/10

75.6 = 75+0.6 = 75+6/10gcd(6,10) = 2

75.6 = 75+0.6 = 75+6/10gcd(6,10) = 275.6 = 75+(6/2)/(10/2) = 75+3/5 = 378/5

#4) 117 3/5

117.6 = 117+0.6 = 117+6/10

117.6 = 117+0.6 = 117+6/10gcd(6,10) = 2

117.6 = 117+0.6 = 117+6/10gcd(6,10) = 2117.6 = 117+(6/2)/(10/2) = 117+3/5 = 588/5

Simplify a•a²•a³ of the following

professor190 [17]

Answer:

a^6

Step-by-step explanation:

when multiplying exponents, add the exponents together. you can distribute to prove it, a^2 is a•a, a^3 is a•a•a so by bringing it together you get a•(a•a)•(a•a•a) which gets a 6 times or a^6

The solution to a system of two linear equations is (4, -3). One equation has a slope of 4. The slope of the other line is the n

astraxan [27]

Answer:

Hello,

First equation is false

Second equation is true

Step-by-step explanation:

1)

(4,-3) is a point of the line y=4x-19 since

-3=?4*4-19

-3=-3

2)

(4,-3) is not a point of the line y=1/4x-2 since

-3=? 1/4*4-2

-3=? 1-2

-3≠-1

I have written that because it is difficult for me to understand

"the negative reciprocal of the slope of the first"

the negative reciprocal of 4 should be -1/4.

Equation y=1/4x-2 is false.

Find the magnitude and direction in degrees of the vector v=6i+2 seq31

masha68 [24]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the vector

v = 6i + 2√3j

The Magnitude of a vector:

$\mathrm{Computing\:the\:Euclidean\:Length\:of\:a\:vector}:\quad \left|\left(x_1\:,\:\:\ldots \:,\:\:x_n\right)\right|=\sqrt{\sum _{i=1}^n\left|x_i\right|^2}$

$=\sqrt{6^2+\left(2\sqrt{3}\right)^2}$

$=\sqrt{36+12}$

$=\sqrt{48}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}$

$=\sqrt{3}\sqrt{2^4}$

$=4\sqrt{3}$

The Direction of a vector:

tan Ф = y/x

y=2√3

x = 6

tan Ф = y/x

= 2√3 / 6

= √3 / 3

$\theta \:=tan\:^{-1}\left(\frac{\sqrt{3}}{3}\right)$

$\:\theta \:=\frac{\pi \:}{6}=30^{\circ \:}$
