It tells you that over these intervals the balloon is going at a constant speed.
Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k
Find k using the point (-8,-4)
y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k
equation of direct variation is y=1/2k
Answer:
a. 6, b. 99, c. 63
Step-by-step explanation:
A) The function s(t) is in the vertex form. The standard vertex form is a(x-h)+k where the vertex is (h,k). The vertex is the highest (or lowest in some cases) point of the graph, so if we use s(t) to get the vertex we get that h=6 and k=99. This means that for a student to get a perfect score they need to study 6 hours
B) We can just take the k value from the first question because that's the highest value for s(t), so the highest score will be 99
C) For this one just plug in 0 for time, so -(0-6)^2+99. This equals -(-6)^2+99, which equals 99-36 =63
Asheville had about 20 more inches of rain and it rained for about 40 more days than Wichita
subtract both rainfall and days for Wichita from the same quantities in Asheville
47.71 - 28.61 = 19.1 , about 20 inches
124 - 85 = 39, about 40
both quantities rounded to the nearest 10
Answer:
It's probably a^6
Step-by-step explanation:
a^2 * a^4
a^2+4
a^6
