Answer:
The answer is 7
Step-by-step explanation:
25 times 25=625
24 time 24=576
625-576=7
And the square root of 49 is 7.
If you pick only positive numbers, the absolute value will have no effect, and the original set and the set of the absolute value will be exactly the same:
is still
Y = -(1/2)(x-2)² +8
Re write it in standard form:
(y-8) = -1/2(x-2)² ↔ (y-k) = a(x-h)²
This parabola open downward (a = -1/2 <0), with a maximum shown in vertex
The vertex is (h , k) → Vertex(2 , 8)
focus(h, k +c )
a = 1/4c → -1/2 = 1/4c → c = -1/2, hence focus(2, 8-1/2) →focus(2,15/2)
Latus rectum: y-value = 15/2
Replace in the equation y with 15/2→→15/2 = -1/2(x-2)² + 8
Or -1/2(x-2)² +8 -15/2 = 0
Solving this quadratic equation gives x' = 3 and x" = 2, then
Latus rectum = 5
Answer:115 miles/hour
Step-by-step explanation: one mile equals to 5280 feet, so 607200 divided into 5280 is 115 and as your timing don’t change you can convert only the distance
