Answer:
D=(-infinity, +infinity)
R=(-infinity, 4]
Step-by-step explanation:
I think that 2 is an exponent so you function is f(x)=-3(x-5)^2+4
So if this is the case this is a parabola open down when a vertex of (5,4).
Visualize or draw a rough picture of that because that is all you need to answer this question.
The domain for a parabola function is always all real numbers (do notice I said parabola function).
The range for this parabola is (-infinity, 4] since open down and the highest point has y value 4.
If it didn't have that piece cut out on the bottom, it would be a rectangle that's 9cm wide and 5cm high. Its area would be 9x5= 45 cm².
But that piece is cut out of the bottom. The cut-out piece is 3cm wide and 3cm high, so its area is 3x3= 9 cm².
9 cm² have been cut out of the 45 cm² of the complete big rectangle. So the remaining area of the figure is 45 - 9 =<em> 36 cm²</em> .
No, your answer are wrong (I assume that the question asks to simplify the roots). You can only remove (their square is placed in from of the root and multiplied by it) the numbers from the root that are squares, the lest must stay, like this:

no roots are among the factors, nothing can be removed

nothing can be removed

nothing can be removed


nothing can be removed

nothing can be removed

nothing can be removed

nothing can be removed


nothing can be removed


(47 is prime) nothing can be removed
Answer:
13
Step-by-step explanation:
use this using the FOIL Method. 5⋅5+5(2√3)−2√3⋅5−2√3(2√3)Simplify
hope this helps
AC = 30 mm (millimeters)
CF = 20 mm (millimeters)
EG = 0.1 m (meters)
The last question only had one “m” so I’m assuming it’s meters
