a) The gradient of a line perpendicular to AB is -2.
b) equation of line is y=-2x+6
<h3>What is gradient?</h3>The gradient is the measure of the steepness of a straight line.
a)The gradient of line is
=(-2-2)/(7+1)
=-4/8
=-1/2
So, gradient of a line perpendicular to AB is -2
b)The coordinates of mid point (3, 0)
m = -2
So,
0= -6+ b
b= 6
So, equation of line is y=-2x+6

EXPLANATION
We use the Altitude Theorem to determine the value of h.
According to the Altitude Theorem, the height, h is equal to the geometric mean of the two segment created by the leg of the altitude on the hypotenuse.
This implies that:
That's,
to the nearest tenth.
Answer:
Step-by-step explanation:
The model for an exponencial function is:
'c' is the value of the asymptote, so we have c = 3.
To find the value of 'a', let's use the point (0,5):
Now, to find the value of 'b', let's use the point (1, 7):
So our function is:
Let's check if the point (-1, 4) is inside our function:
