Answer:
(i) In triangle RTO and QSR
Given,
⇒∠RTO=∠OSR=90
o
(QS⊥PR and RT⊥PQ)
⇒QS=RT
⇒QR=RO ....Hypotenuse
∴△RTQ≅△QSR ....RHS criterion
(ii) By using part(1) of a solution, we get
∠TQR=∠SRQ ....By C.P.C.T
⇒∠PQR=∠PRQ
Step-by-step explanation:
Answer:
x=21
Step-by-step explanation:
Answer: 61.1
Step-by-step explanation: The answer would be 61.1 because .062 is greater than .05, which means that it rounds up.
Answer:
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex ad a is a multiplier
Here (h, k ) = (8, - 1 ) , then
y = a(x - 8)² - 1
To find a substitute (0, - 17 ) into the equation
- 17 = a(0 - 8)² - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
= a , that is
a = -
y = - (x - 8)² - 1 ← equation of parabola
