Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b​

Answers

Answer:

h = √72 in.

Step-by-step explanation:

Height of the cone using pythagorean theorem, a² + b² = c², where:

a = h

b = ½(6) = 3 in.

c = 9 in.

Plug in the values

h² + 3² = 9²

h² + 9 = 81

h² + 9 - 9 = 81 - 9

h² = 72

h = √72

Answers

I think it is A it has to be x<1 but i am not totally sure

Answer:

For x<1, answer would be A.

Step-by-step explanation:

Since the less than sign doesn't have a line under it "making it less than or equal to" the dot on the graph is not shaded, and if you simply read the inequality, x is less than 1, so it goes in the direction less than 1.

C. Find the equation that is parallel to y = 12x-2 and crosses the point (6,2)

Answers

Answer:

The equation of line a is y=(1/2)x−1, and it passes through point (6,2).

       line b is: y = -2x + c and we use point (-6,2) to find b.

      2 = -2(-6) + c

     14 = c

The equation for line b is: y = -2x + 14

The y-intercept (which is the point where x=0) is the point (0,14.)        So, y=14

Step-by-step explanation:

hope this helps       :)
