Slope of the line will be -3/2
Answer: C
Step-by-step explanation:
x = 2
- 6
x + 6 = 2
((x+6)/2 = )^2
(x+6/2)^2 = y+2
y = (x+6/2)^2 -2
y= 1/4x^2 +3x +7
Answer:
1) a = 1.6 2) f = 0.53
Step-by-step explanation:
1) 6a = 10 2) 48 = 90f
6a/6 = 10/6 90f/90 = 48/90
a = 1.6 f = 0.53
sorry i could only do the first two, i think those are right
Answer:
please mark me as brainlist please
Step-by-step explanation:
we know, ∠BGA = 90
In right angled triangle BGA
AB = 12 cm (diameter of circle)
⇒ (AB)2 = (AG)2 + (BG)2
⇒ 122 = 82 + (BG)2
⇒ BG = 4√5
In right angled triangle BCG
Let CG be x cm.
⇒ (BC)2 = (CG)2 + (BG)2
⇒ (BC)2 = x2 + (4√5)2 ----(1)
As we know,
⇒ (BC)2 = CG × CA ----(2)
From equation (1) and equation (2)
⇒ x2 + (4√5)2 = x × (x + 8)
⇒ x2 + (4√5)2 = x2 + 8x
⇒ 8x = 80
⇒ x = 10 cm
From equation (2)
⇒ (BC)2 = CG × CA
⇒ (BC)2 = 10 × 18 = 180
⇒ BC = √180 = 6√5
6 × 5 = 30
