Answer:

4 1/12

Step-by-step explanation:

a = 5/6        b = 3 1/4 = 13/4

To add 5/6 + 13/4, we have to make the denominators the same:

20/24 + 78/24 = 98/24
To make it back to a mixed fraction:

4 2/24
4 1/12

Answer:

4\frac{1}{12}

Step-by-step explanation:

Given the following question:

a+b
a=\frac{5}{6}
b=3\frac{1}{4}
\frac{5}{6} +3\frac{1}{4}

To find the answer we have to convert the mixed number into an improper fraction, find the common denominator, and then add the numerators.

\frac{5}{6} +3\frac{1}{4}
3\frac{1}{4} =4\times3=12+1=\frac{13}{4}
\frac{5}{6} +\frac{13}{4}
\frac{5}{6} \times4=\frac{20}{24}
\frac{13}{4} \times6=\frac{78}{24}
20+78=98
\frac{98}{24} \div2=\frac{49}{12}
\frac{49}{12} =49\div12=4\frac{1}{12}
=4\frac{1}{12}

Hope this helps.

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.
HACTEHA [7]

Answer:

-\frac{1}{2}y^2-4y+1=x

Step-by-step explanation:

A parabola has a focus of F(8.5,−4) and a directrix of x=9.5.

General form of  horizontal parabola is

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

the distance between directrix and focus is the value of p

so p = 8.5 - 9.5 = -0.5

Focus is (h+p , k), given focus is (8.5, -4)

So k = -4 and h+p = 8.5

we know p = -0.5

h +p = 8.5

h - 0.5 = 8.5

so h= 9                   and k = -4

vertex is (h,k) that is (9, -4)

Now plug in the value in the general equation

(y-k)^2=4p(x-h), k= -4, h= 9 , p = -0.5

(y+4)^2=4(-0.5)(x-9)

(y+4)^2=-2(x-9)

y^2+8y+16=-2x+18

subtract 18 on both sides

y^2+8y-2=-2x

Divide whole equation by -2

-\frac{1}{2}y^2-4y+1=x
