Answer:
1st
Vertex
we have
f(x)=x²-18x+88
let
y=x²-18x+88
comparing above equation with ax²+bx+c
we get
a=1
b=-18
c=88
now
vertex(x,y)=(-b/2a,f(-b/2a))
x=(18/2×1)=9
y=f(9)=9²-18×9+88=7
SO
VERTEX(X,Y)=(9,7)
=
Answer:
256m²
Step-by-step explanation:
A=1/2{(b+b)×h}
A=1/2{(13+19)×16}
A=1/2(32×16)
A=1/2(512)
A=256
Answer:
(A)The sample comes from a population of tires with 60,000 miles where 5% of tires are worn out.
Step-by-step explanation:
The tire manufacturer has a 60,000 mile warranty for tread life. To verify the authenticity of its claim, it picks a sample of 250 tires (out of the population of tires) that have been used for 60,000 miles.
Given the hypothesis:
: The proportion of tires that are worn out after 60,000 miles is equal to 0.05.
: The proportion of tires that are worn out after 60,000 miles is less than 0.05.
It is assumed that 5% of the tires in the sample are worn out and the hypothesis is formulated to prove or disprove this assumption.
Answer:
g(x) = x^2 -2.
Step-by-step explanation:
Vertical translations are represented by k, which in f(x) is equal to 6. Translating this down 8, we have a k value of -2.
Answer:
Step-by-step explanation:
Given
On first day bag contained 1 kernels
on second bag contained 2 kernels of corn
on third day bag contained 4 kernels of corn
on n th day bag contains
kernels of corn
thus on 26 th day bag contains
kernel
Each kernel weigh 0.07 gm
Therefore
kernels weighs 
Therefore on 26 th day
kernel weighs 23,488.1024 kg
