Answer:
noooo i clicked on one before nd it was a guys dickk dont trust it girll
Step-by-step explanation:
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
24% decrease
550 - 420 = 130
130/550 = 24%
Answer:
76
Step-by-step explanation:
PQRS is a Rhombus.
Property of Rhombus : -
All sides are equal.
So,
PQ = QR = RN = NP
RN = 5x + 16
QR = 9x - 32
QR = RN
5x + 16 = 9x - 32
9x - 32 = 5x + 16
9x - 5x = 16 + 32
4x = 48
x = 48 / 4
x = 12
Substitute x = 12 in RN,
RN = 5x + 16
= 5 ( 12 ) + 16
= 60 + 16
RN = 76
Since,
PQ = QR = RN = NP
Therefore,
PQ = 76
102
the angles are alternate so they add up to 180
180-78=102
hope this helps :)
if you need me to explain more just let me know :)
