Answer:
a) XY , XVY
b) 248°
c) UV , UY
d) 6√5 = 13.42
Step-by-step explanation:
a) The minor arc is XY
The major arc is XVY
b) ∵ The measure of the minor arc is 112°
∵ The measure of the circle is 360°
∴ The measure of the rest arc = 360 - 112 = 248°
c) UV is the tangent to the circle
UY is the secant to the circle
d) ∵ UV is a tangent to the circle at V
∵ UY is a secant to the circle
∴ (UV)² = (UX) × (UY)
∵ UX = 9 and XY = 11 ⇒ ∴ UY = 11 + 9 = 20
∴ (UV)² = 9 × 20 = 180
∴ UV = √180 = 6√5 = 13.42

Answer: 640
Step-by-step explanation:
if 256 is 40%, then 64 is 10%, making 640 100%
<h3><u>d^3 - 4bd^2 + 16b^2d - 64d^3 is the expanded binomial.</u></h3>
The binomial theorem involves Pascal's triangle, and essentially gives you the coefficients for the formula you're going to use to expand it.
In this case, the coefficients will be 1, 3, 3, and 1.
We can set up our formula like this:
(a + (-b)) = a^3 + a^2b + ab^2 + b^3
Now we can just plug in our values:
(d + (-4b))^3 = d^3 + d^2(-4b) + d(-4b)^2 + (-4b)^3
Now, we can simplify the equation.
(d + (-4b))^3 = d^3 - 4bd^2 + 16b^2d - 64d^3
