I’m not really sure :( I think these are right tho
The answer is D. -(4x-3)(5x-2)
Answer:
x = 250°
Step-by-step explanation:
"Angle formed between a chord and tangent intersecting on a circle measure the half of the intercepted arc"
From the figure attached,
Angle between the chord and the tangent = 55°
Measure of intercepted arc (minor arc AB) = h°
Therefore, 55° =
And m(minor arc AB) + m(major arc AB) = 360°
h° + x° = 360°
110° + x° = 360°
x° = 360° - 110°°
x = 250°
Therefore, measure of the intercepted arc is 250°.
Answer:
Step-by-step explanation:
<u>1)</u>
f(x) = -6x + 3
To get the inverse of this, make x be the subject of the formula.
let f(x) = y
6x = 3 - y
x = (3 - y)/6
∴ f(x) = (3 - x)/6
Truly f and g are inverse functions.
<u>2)</u>
f(x) = -3x²+ 5
let f(x) = y
y = -3x² + 5
3x² = 5 - y
x² = (5 - y)/3
x = √[(5 - y)/3]
f(x) = √[(5 - x)/3]
Truly f and g are inverse function.
