Answer:
x
=
5 and (
5
,
−
9
)
Explanation:
The equation of a parabola in vertex form is.
2
2
y
=
a
(
x
−
h
)
2
+
k
2
2
Where (
h
,
k
) are the coordinates of the vertex and a is a multiplier
f
(
x
)
=
(
x
−
5
)
2
−
9 is in this form
with (
h
,
k
)
=
(
5
,
−
9
)
⇒
vertex =
(
5
,
−
9
)
the axis of symmetry passes through the vertex is vertical with equation
x
=
5
← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}
Since you can only multiply the 2 and 4 together, you get 8x^2.
Answer:
do you need to simplify or solve for x?
Step-by-step explanation:
The answer is 17/5. First you multiply 5*3=15 then you add 2 which your answer is 17/5.
Answer:
Step-by-step explanation:
Given that a simple random sample of 40 ten-gram portions of the food item is obtained and results in a sample mean of x overbarequals2.5 insect fragments per ten-gram portion.
a) By central limit theorem for samples randomly drawn with large sample sizes (atleast 30) the sample mean follows a normal distribution irrespective of the original distribution it belonged to.
b) Mean of X bar = Sample mean = 5
Std error of x bar = s/sqrt n =
c) P( x bar >5.8) = P(Z>)
=0.4930
