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:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
a-(9*x^2-6*x+1)=0
STEP
1
:
Equation at the end of step 1
a - ((32x2 - 6x) + 1) = 0
STEP
2
:
Equation at the end of step 2
a - 9x2 + 6x - 1 = 0
STEP

Solving a Single Variable Equation:
3.1 Solve a-9x2+6x-1 = 0
Answer:
the first one and the last three
Step-by-step explanation:
that should be it.
Hey there. Discrete data is usually date which is counted. Continuous data is data that can be measured, and can take any type of value. So for this, a) Continuous, b) Discrete c) Continuous, d) Discrete
Hopefully this should be right! :)
