Answer:

Additional information required is

<DBA = 90°

Step-by-step explanation:

<DBA + <DBC = 180° [Linear pair]

=> <DBA = 180° - <DBC

=> <DBA = 180 - 90

=> <DBA = 90

Hence, both the angles <DBA = <DBC = 90°

As we know that when a perpendicular bisector bisects a straight line both the angles should be,

180° ÷ 2 = 90°

And above conditions also prove that

<DBA = <DBC = 90°

Hence, DE is a perpendicular bisector of AC

Elenna [48]

Eg. d stands for the number of dimes, n stands for the number of nickels
a dime worth 10 cents, 1 nickel worth 5 cents

The equation for "There are 10 coins in a jar" is
d + n = 10

The equation for "The coins are worth a total of 70 cents" is
10d + 5n = 70

If u(x)= x^5-x^4+x^2 and v(x)= -x^2, which expression is equivalent to (u/v)(x)? Ox^3-x^2 O -x^3+x^2 O-x^3+x^2-1 Ox^3-x^2+1

djverab [1.8K]

Answer:

C. -x^3 + x^2 - 1

Step-by-step explanation:

Given

u(x) = x^5 - x^4 + x^2 and v(x) = -x^2

(u/v)(x) =

(x^5 - x^4 + x^2) /(- x^2) =
- (x^3 - x^2 + 1) =
-x^3 + x^2 - 1

Correct option is C
