Answer:
(-1 , 7)
Step-by-step explanation:
Read the symbol ∩ as the word "AND"
x-2 < 5 AND x+7 > 6
x< 5+2 AND x > 6-7
x < 7 AND x > -1
All the numbers greater than -1 AND less than 7
Interval (-1 , 7)
Answer:
∠ D = 35°
Step-by-step explanation:
∠ D is formed by a tangent and a secant and is one half the difference of the measure of the intercepted arcs, that is
∠ D = 0.5( arc EH - arc GE )
= 0.5(95 - 25)° = 0.5 × 70° = 35°
Question 1: Rocket #1
Question 2: Rocket #3, the hight was 65 meters, 4 seconds
Question 3: Rockets #2 & #3
Question 4: Rocket #1 was launched from 5 meters, Rocket #2 was launched from 20 meters, Rocket #3 was launched from 10 meters
Question 5: Rockets #2 & #3, the height was 45 meters in 1 second
Question #6: Rockets #2 & #3
I can’t see part B of question #6 because your peardeck notification is covering it up. I hope I was helpful!

Answer:
13 +
or
22.43398... (depends on how you round it)
Step-by-step explanation:
1. The question stated that the radius of the circle O is 5, so the length of AO and CO is 5.
2. Since line AB and line CB are both tangent to the circle, they have the same length. CB is 8, so AB will also be 8.
--> Both triangle AOB and COB share one side, and the other side (radius) has the same length, so the third side must be the same length
3. Tangent means having a 90-degree angle with the radius. We know that the triangle AOB is a right triangle since the angle OAB is 90 degrees.
We can use the Pythagorean theorem to find side OB. OB^2 = AO^2 + AB^2.
--> OB^2 = 25 + 64
--> OB^2 = 89
--> OB =
Now that we know the lengths of all three sides, we can add them up.
--> 5 + 8 +
--> 13 +
or
--> 22.43398113....
