Answer:
x ≈ 4.2 (nearest tenth)
Step-by-step explanation:
The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).
An isosceles triangle comprises two right triangles, each with:
- base = 2 units
- height = 3.7 units
- hypotenuse = x units
Therefore, to find x use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ a² + b² = c²
⇒ 2² + 3.7² = x²
⇒ x² = 17.69
⇒ x = √(17.69)
⇒ x = 4.2 (nearest tenth)
Answer:
<h3>y - 3 = 2(x+1)</h3>
Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)
