Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

harina [27]

The equation of line is:

$y=-\frac{1}{2}x+6$

Further explanation:

Given

y = 2x + 2

Comparing it with standard form:

y=mx+b

Let m1 be the slope of given line

$m_1=2$

We know that product of slopes of two perpendicular lines is -1

Let m2 be the slope of second line

$m_1.m_2=-1\\2*m_2= -1\\m_2 = -\frac{1}{2}$

Putting the value of m2 in standard form

$y=-\frac{1}{2}x+b$

To find the value of b, putting (6,3) in equation

$3=-\frac{1}{2}(6)+b\\3=-3+b\\3+3=b\\b=6$

Putting the values of b and m, we get

$y=-\frac{1}{2}x+6$

The equation of line is:

$y=-\frac{1}{2}x+6$

The function h(t) = -16t- + 96t + 6 represents an object

AveGali [126]

Answer:

3 seconds

Step-by-step explanation:

Maximum height=150

150=-16t^2+96t+6

-16t^2+96t-144=0

-16(t^2-6t+9)=0

-16(t-3)^2=0

t=3 seconds
