Y = a(x + 2)(x - 3) : equation of the parabola in factored form 10 = a(5 + 2)(5 - 2) : (5 , 10) is a point on the graph of the parabola and therefore satisfies the equation of the parabola. a = 5/7: solve the above equation for a.
Answer:
Value of x is, 8
Step-by-step explanation:
Given: 
,.....[1]
To find the value of x:
Using exponent rules:
Taking square both sides in [1] we have;
Simplify:
or
Multiply both sides by 
we get;
Simplify:
or
Simplify:
x = 8
Therefore, the value of x is, 8
Answer:
rate of change
Step-by-step explanation:
Answer:
first one
relationship between base and perpendicular is
given by tan angle
tan x=P/h
remember perpendicular is opposite side of taken angle
tan x=13/8
<x=tàn-¹(13/8)=58.39°
for second one
relationship between base and hypotenuse is given by cos angle
cos G=b/h
cos G=24/32
<G=cos-¹(24/32)=41.4 is your answer
1760 divided by 0.07 = the cost
So the answer is 25142 (rounded)
