FrozenT [24]

Answer:

\frac{25}{4}

Step-by-step explanation:

a + b = \frac{1}{2} + 2 = 2 \frac{1}{2} = \frac{5}{2}, thus

(a + b)² = (\frac{5}{2} )² = \frac{5}{2} × \frac{5}{2} = \frac{5(5)}{2(2)} = \frac{25}{4}

Identify the focus and directrix of the parabola whose equation is (y-4)^2 = -12(x-7)
sertanlavr [38]

Answer : Focus (4,4)  , directrix x=10

Given equation is

(y-4)^2 = -12(x-7)

The given equation is in the form of

(y-k)^2 = 4p(x-h)

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

52 Bananas, 25% increase. What's the new amount?
vredina [299]
If there were 52 bananas and a percent of 25 was added 
Therefore we divide 25 by 100 which is 0.25 then multiply it by 52 which is 13 
then add 13 to 52 which is 65 so it was increased to 65 bananas
