Answer:

A) (1.2)^{2} = 1.44

B)2^ 3+17-(3\times 4) = 13

C)\frac{(9)^2}{(3)^3} = 3

Step-by-step explanation:

Here, the given expressions are:

A) (1.2)^{2}

Solving this, we get

(1.2)^{2}  = 1.2  \times 1.2 = 1.44

⇒(1.2)^{2}  = 1.44

B) 2^ 3+17-(3\times 4)

Now, solving this, we get

2^ 3+17-(3\times 4) = (2 \times 2 \times2) + (17 -12)\\=8 + 5 = 13

⇒2^ 3+17-(3\times 4) = 13

C) \frac{(9)^2}{(3)^3}

Simplifying this, we get

\frac{(9)^2}{(3)^3} = \frac{(9\times9)}{(3 \times 3\times3)}  = 3

⇒ \frac{(9)^2}{(3)^3} = 3

The equation of line QR is x + 2y = 2. What is the equation of a line perpendicular to line QR in slope-intercept form that cont
Elza [17]

Answer:

y = 2x-4

Step-by-step explanation:

x + 2y = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

First find the slope of the line

2y = -x+2

Divide by 2

y = -1/2x +1

The slope of this line is -1/2

We want a line that is perpendicular, which is the negative reciprocal

-1 /(-1/2) = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the line

6 = 2(5)+b

6 = 10+b

6-10 =b

-4=b

y = 2x-4

What is the y-intercept of the equation of the line that is perpendicular to the line y =
igor_vitrenko [27]

Answer:

y=-5/3x+20

Step-by-step explanation:

Let the equation of the required line be represented as \[y=mx+c\]

This line is perpendicular to the line \[y=\frac{3}{5}x+10\]

\[=>m*\frac{3}{5}=-1\]

\[=>m=\frac{-5}{3}\]

So the equation of the required line becomes \[y=\frac{-5}{3}x+c\]

This line passes through the point (15.-5)

\[-5=\frac{-5}{3}*15+c\]

\[=>c=20\]

So the equation of the required line is \[y=\frac{-5}{3}x+20\]

Among the given options, option 4 is the correct one.
