Answer:
The answer is d
Step-by-step explanation:
I graphed it
-b/2a to get the vertex
3x^2-12+9
-(-12)/(2)(3)=2
plug in 2 to the function
12-24+9=-3 which is the y value on the graph
(2,-3) is the vertex
Answer:
6.9
Step-by-step explanation:
Use the Pythagorean theorem :
a^2 + b^2 = c^2
so,
11^2 + b^2 = 13^2
121 + b^2 = 169
b^2= 48
b = 6.928
Round to the tenth : 6.9
Answer:
the answer is ≊20.4 I think not 100% sure
Step-by-step explanation:
if right please mark this answer brainliest
122 <---answer
Reason:
The decimal is closer to 122 than 123.
Formula for geometric sequence is aₓ = arⁿ⁻1
a₅=4(3)⁵⁻¹
a₅=4(3)⁴
a₅=4(81)
a₅=324
