Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada wal

Setler [38]

Answer:

The Time taken by Elena and Jade to meet up is 2.5 hours

Explanation:

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.

The function p(x) = –8x2 – 64x can be written in vertex form p(x) = a(x – h)2 + k, where a =

nydimaria [60]

Means compplete the square on one side

basically get into form $f(x)=a(x-h)^2+k$

ok, group x terms
$p(x)=(-8x^2-64x)$
factor out linear coefient (-8)
$p(x)=-8(x^2+8x)$
take 1/2 of the linear coefient and square it
8/2=4, 4^2=16
add positive and negaitve of that inside parntheaese
$p(x)=-8(x^2+8x+16-16)$
factor perfect square
$p(x)=-8((x+4)^2-16)$
expand
$p(x)=-8(x+4)^2+128$

in vertex form it is $p(x)=-8(x+4)^2+128$
