Answer:
27
Step-by-step explanation:
If you 9 times 3 u get 27
Range of is [4,∞).
<u>Step-by-step explanation:</u>
Here we have , function , We need to find range of this function . Let's find out:
In the function , Let's focus on : It's a perfect square whose value will be always positive and greater then equal to zero i.e.
⇒ , So minimum value of is 0 at x=-3 . ∴
⇒
⇒
⇒
Minimum value of is 4 , And maximum value of can be ∞ as value of x can be increased . Therefore , Range of is [4,∞).

i believe this is correct.
Answer:
Step-by-step explanation:
Start
<F = <Q Given
<GPF = <RPQ Vertically opposite angles
<FGP = <QRP A triangle has 180 degrees. 2 equal angles means the third pair must be equal
Triangle GPF ~ Triangle RPQ AAA
end
I don't see any way to make these triangles similar except by stating the statement and why it is so. There really are no yes / no choices. If you get another answer, choose it.
20
JL/LE = 90/27 Given
KL /LD = 90/27 Given
<JLK = <DLK Vertically opposite
Are the ratios equal Yes Then is the angle included Yes
Then the triangles are similar.
Are the ratios not equal No then the triangles cannot be similar
Is the angle not included Then similarity cannot be proved.
ΔJLK ≈ ΔDLK Equal Ratios and included angle === similarity
Answer:
8
Explanation:
cotx – 11 = -9
To solve algebraically, try to get cotx alone.
First, add 11 to both sides:
cotx – 11
+ 11 = -9
+ 11cotx = 2
Now divide by
on both sides, which is the same as multiplying the other side by 4:
cotx ÷
= 2 ÷
cotx = 8
