Answer:
Vertex is (-5, -1)
(-3, 3) is a point on the parabola.
Step-by-step explanation:
f(x) = x² + 10x + 24
Let (h, k) be the vertex
h = -b/2a = -10/2(1) = -5
k = f(-5) = (-5)^2 + 10(-5) + 24
= 25 - 50 + 24 = -1
Vertex is (-5, -1)
Now, let x be some value different than -5, say -3
f(-3) = (-3)^2 + 10(-3) + 24
= 9 - 30 + 24 = 3
So, (-3, 3) is a point on the parabola.
p(x) * r(x) = ab^x * cd^x
p(x) * r(x) = (a*c)*(b^x*d^x)
p(x)*r(x) = ac(bd)^x
For the last step, I used the rule that (ab)^x = a^x*b^x
<h3>Final Answer: ac(bd)^x</h3>
Answer:
Step-by-step explanation:
Money left Rs. 800
Money spent = 75%
- Rs 800 = 25%
- 800 = 0.25x
- x = 800/0.25
- x = 3200
Initial amount was Rs. 3200
Answer:
26.5%
Step-by-step explanation:
i did the math, that answer should be correct, but the question is stated strange.
The correct answer is C.
this is because 452.7*10^3=452700
and 2.7*10^5=270000
452700-270000=182700
which when expressed in scientific notation is 1.827*105
