Find the value of x and thank for answer
lakkis [162]
The value for x is 102 degrees

First we can find the second value in the triangle by subtracting 141 from 180. This works because when added together these two angles come together to from a line (180 degrees) because this value is now known (39 degrees) we can subtract both from 180:

180-39-39= x = 102

Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4
lapo4ka [179]

Try this option:

1) if V(0;0) and x= -4, then common view of the required equiation is:

(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;

2) if the V(0;0), then h=k=0 and the required equiation is:

y²=4px;

3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:

y²= -16x

answer: y²= -16x

Vsevolod [243]

Answer:

The result is

\frac{5}{2}

Or

2.5

Step-by-step explanation:

We want to simplify

\frac{5}{8}  \times 4

We know that 4 goes into 8 twice.

This implies that:

\frac{5}{8}  \times 4 =  \frac{5}{2}

We can convert the result into decimals as follows:

\frac{5}{2}  =  \frac{25}{10}  = 2.5
