The answer is 315 as the formula is : a+b/2•h.
Part A:
y=mx+b
621=83(7)+b
Part B:
621=83(7)+b
621=581+b
621-581=b
b=40
Insurance cost is 40$
Answer:
Step-by-step explanation:
β ∈ { 0° , 18° , 180° , 198° }

y = 2 + x^6
y - 2 = x^6
x = (y - 2)^1/6

Well, solving this integral
= 2,69279
linear; y = x – 2 is answer! pls mark me as brainliest i need only 2 more to rank up! Hope I Helped
