A tree 24 m tall casts a shadow 7 m long. Find the distance between the top of the tree and the foot of the shadow.

25 m

Step-by-step explanation:

You have to use the Pythagorean theorem to find the answer.

A² + B² = C²

Height² + Shadow length² = Distance²

Distance² = 24² + 7²

Distance² = 576 + 49

Distance² = 625.

Square root both sides which gives you 25

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
