since \to :  x \sqrt[y]{ {n}^{z} }  = x( {n}^{ \frac{z}{y} } ) \\ then \: lets \: solve \: both \: values \: separately \to :  \\ \underline{ \boxed{solution \: to \:  \boxed{a}}} \\  120 \sqrt[3]{ {n}^{a} }  = 3 \sqrt{n} (40 \sqrt[6]{n} ) \\ 120 \sqrt[3]{ {n}^{a} }  = 3 \sqrt{n}  \times 40 \sqrt[6]{n} \\ 120 \sqrt[3]{ {n}^{a} }  = 120 (\sqrt{n} \times \sqrt[6]{n} ) \\ \sqrt[3]{ {n}^{a} }  = (\sqrt{n} \times \sqrt[6]{n} ) \\  {n}^{ \frac{a}{3} }  = {n}^{ \frac{1}{2} } \times {n}^{ \frac{1}{6} } \\ \frac{a}{3}  =  \frac{1}{2}   +   \frac{1}{6}  \\  \frac{a}{3}  =  \frac{4}{6}  \\ 6a = 12 \\ a =  \frac{12}{6}  =  2 \\ \underline{ \boxed{a  = 2 \:}}  \\  \\ \: \underline{ \boxed{solution \: to \:  \boxed{b}}} \\  27 \sqrt[4]{ {n}^{b} }  = 3 \sqrt{n} (9 \sqrt[4]{n} ) \\ 27 \sqrt[4]{ {n}^{b} }   = 3 \sqrt{n}  \times 9 \sqrt[4]{n} \\ 27 \sqrt[4]{ {n}^{b} }  = 27 (\sqrt{n} \times \sqrt[4]{n} ) \\ \sqrt[4]{ {n}^{b} }  = (\sqrt{n} \times \sqrt[4]{n} ) \\  {n}^{ \frac{b}{4} }  = {n}^{ \frac{1}{2} } \times {n}^{ \frac{1}{4} } \\ \frac{b}{4}  =  \frac{1}{2}   +   \frac{1}{4}  \\  \frac{b}{4}  =  \frac{3}{4}  \\ 4b = 12 \\ b =  \frac{12}{4}  =  3 \\ \underline{ \boxed{b  = 3 \:}}  \\ hence \to :  \\  \underline{ \underline{\boxed{a  = 2 \:}} \underline{ \boxed{b  = 3 \:}}}

What is the y-intercept of the equation of the line that is perpendicular to the line y =
Luda [366]

Answer:

y intercept =10

line y=-x+10

Step-by-step explanation:

Let y=mx+b is the required line.

<u>Slope of perpendicular lines :</u> If m_{1} and m_{2} be slope of two perpendicular lines. Them m_{1}\times m_{2}=-1

y=mx+b is perpendicular to y=x+10

the slope of y=x+10  is =1

m\times 1=-1\\m=-1

Hence eqn is y=-x+b

This equation passes through (15,-5)

-5=-15+b\\b=-5+15\\b=10

so the line is y=-x+10

<u>y-intercept :</u>

Substitute x=10

y=0+10\\y=10

Can someone help plsssss !!!!

The area of the circle is 3.14 square millimeters

<h3>Calculating Area</h3>

From the question, we are to the area of the circle

The area of a circle can be determined by using the formula,

A = πr²

Where A is the area of the circle

and r is the radius of the circle

From the given information,

r = 1 mm

and π = 3.14

Putting the parameters into the equation, we get

A = 3.14 × 1²

A = 3.14 × 1

A = 3.14 mm²

Hence, the area of the circle is 3.14 square millimeters

If<br>A = i +3j -2K and B=4i-2j+4k<br>Find (2A+B).(A-2B)​
Marizza181 [45]

GIVEN :

a = 1/√10 ( 3i + k) and

b = 1/7 ( 2i + 3j - 6k)

TO FIND :

( 2a- b) . [ ( a x b ) x ( a + 2b)]

SOLUTION :

◆Going with the equation given,

( 2a - b) . [ ( a x b ) x ( a + 2b)]

= (2a - b) [( a×b×a) + 2(a×b)×b]

◆BAC - CAB RULE,

A×B×C = B( A.B ) - C(A.B )

= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]

Solving further

= (2a - b )(b - 2a)

= -4a.a -b.b

=-5.

Answer:

( 2 - b) . [ ( a x b ) x ( a + 2b)] = -5
