D. 1mm/10cm is the correct answer choice.
Answer:
n = -1
Step-by-step explanation:
n^2 + 5n + 1 = 3n
N^2 +2n +1 = 0 (subtract 3n from both sides)
(n+1)(n+1) = 0 (factor
n+1 =0; n= -1
n+1 = 0 ; n=-1
Answer:
200 in3
Step-by-step explanation:
To find the volume of a rectangular prism you multiply each dimension to each other. 8*2 is 16, and 16*12.5 is 200. This means the volume is 200 in3.
Hope this helps :)
Answer:
Step-by-step explanation:Let's solve your equation step-by-step.
(4564644)(4434688)=124x2
Step 1: Simplify both sides of the equation.
20242771971072=124x2
Step 2: Subtract 124x^2 from both sides.
20242771971072−124x2=124x2−124x2
−124x2+20242771971072=0
Step 3: Subtract 20242771971072 from both sides.
−124x2+20242771971072−20242771971072=0−20242771971072
−124x2=−20242771971072
Step 4: Divide both sides by -124.
−124x2
−124
=
−20242771971072
−124

Answer : Focus (4,4) , directrix x=10
Given equation is
The given equation is in the form of
Where vertex is (h,k)
h = 7 and k = 4 so vertex is (7,4)
4p = -12 so p = -3
Focus is (h+p, k)
h=7, k=4 and p = -3
focus is (7-3, 4) that is (4,4)
now we find directrix
Directrix x= h-p
So x= 7-(-3)= 10
Focus (4,4) , directrix x=10
