So you can set up proportion.
Here, you need to solve for C.
You can do that by multiple both sides by 360 and then you should get
Hope this helps.
Answer:
anwser -10000 n
Step-by-step explanation:
When you write URGENT the Brainly cops think you may be taking a test.
y = ax² + c thru (-1,4) and (0,8)
Substituting in the coordinates of each point for x and y gives two equations:
4 = a (-1)² + c
8 = a (0²) + c = c
From the second one we see c=8. Substituting into the first one,
4= a + 8
a = 4-8 = -4
Answer: a=-4, c=8
Check:
f(x) = -4x² + 8
f(0) = 8, good
f(-1) = -4(1) + 8 = 4, good
From the relation, d is joint proportionaly with r and t.
Thus,d = krt.
Using the first set of given, we could calculate for k.135 = k(45)(3)k = 1
Using the computed value of k.d = krtr = d/ktr = (189)/(1)(3.5) = 54 mph.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
