The first one is supplementary
Answer:
Dilate circle A by a scale factor of 4.
Step-by-step explanation:
Dilating circle A by 4 would be the same as multiplying its radius of 6 by 4, which would make it 24.
The radius of circle B is 24.
Rotating it wouldn't change anything (it's a circle), and I don't think reflecting and translating show circle similarity
Answer:
B -⅓
Step-by-step explanation:
sinx = -3/5
Adjacent² = 5² - 3² = 16
Adjacent = 4
tan(x) = -3/4
-¾ = 2tan(½x)/[1 - tan²(½x)]
-3 + 3tan²(½x) = 8tan(½x)
3tan²(½x) - 8tan(½x) - 3 = 0
tan(½x) = 3, -⅓
Answer:
x = - 4, x = 6
Step-by-step explanation:
To find the x- intercepts let y = 0 , that is
- 3(x + 4)(x - 6) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 6 = 0 ⇒ x = 6
