Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
= 41.85714286 miles/hr
Answer: E. Convenience
Step-by-step explanation:
- A convenience sampling is a method of sampling whose structure is based on accessibility to the researcher .
Given : An internet site asks its members to call in their opinion regarding their web searching habits.
Here the internet site is working according to its accessibility .
Hence, this is a type of convenience sampling .
Hello,
Vertices are on a line parallele at ox (y=-3)
The hyperbola is horizontal.
Equation is (x-h)²/a²- (y-k)²/b²=1
Center =middle of the vertices=((-2+6)/2,-3)=(2,-3)
(h+a,k) = (6,-3)
(h-a,k)=(-2,-3)
==>k=-3 and 2h=4 ==>h=2
==>a=6-h=6-2=4 (semi-transverse axis)
Foci: (h+c,k) ,(h-c,k)
h=2 ==>c=8-2=6
c²=a²+b²==>b²=36-4²=20
Equation is:
Answer:
As x decreases without bound, f(x) increases without bound
As x increases without bound, f(x) approaches 0
Step-by-step explanation:
As x gets more and more negative f(x) gets bigger and bigger
f(x) = (7/10) ^ x but x is negative so flip it and then x is a larger number
(10/7) ^ large number so it will get larger
as → -∞ f(x) →∞
As x gets more and more positive f(x) gets smaller and smaller
f(x) = (7/10) ^ x closer and closer to 0. The denominator gets larger faster than the numerator = 1 / large number
as → ∞ f(x) →0
