The image is a dilation of the pre-image with a scale factor of 3.
check the picture below.
make sure your calculator is in Degree mode.
Answer:
Perimeter is 50
Area is 60
Step-by-step explanation:
To get the perimeter, you add all the lengths of the sides together.
To get the area, you do A=hb * b / 2, which is 60
Answer:
Option 1 and 2.
Step-by-step explanation:
Consider he given inequality is
Splitting the middle term we get
The related equation is
Using zero product property we get
Draw number line and mark -5 and -7 on it.
Now the three intervals are (-∞ , -7], [-7,-5] and [-5,∞).
The set of possible test points for
⇒ (-∞ , -7] → -8, -10
⇒ [-7,-5] → -6
⇒ [-5,∞) → -4, 0, 4, 6
-8,-6,-4 and -10,-6,0 satisfies the given condition.
Therefore, the correct options are 1 and 2.

Correct Question
A sector whose central angle measures 120° has an area of 12 square inches. What is the radius of the circle?
Answer:
Radius of the circle = 3.3851375013 inches
Approximately to one decimal place, radius of the circle = 3.4 inches
Step-by-step explanation:
The formula for the area of a sector is given as:
Area of a sector = θ × π/360 × r²
θ = Central angle in degrees = 120°
Area of a sector = 12 in²
12 = (120° × π)/360 × r²
r² = 12 ÷(120° × π)/360
r² = 12 ÷ 1.0471975512
r² = 11.459178217
r = √11.459178217
r = 3.3851375013 inches
Approximately to one decimal place, radius of the circle = 3.4 inches
