Answer:
y=-5/4x-8
Step-by-step explanation:
2=-5/4(-8)+b
2=10+b
2-10=10-10b
-8=b
8 a.m. to 1 p.m. = 5 hrs
so the temperature changed -3/5 degrees per hr for 5 hrs...
-3/5 * 5 = -15/5 = -3.....so in total, the temperature changed by 3 degrees....it went down 3 degrees
Answer:
The question should say..... How much of the sample is left in......FIVE.....weeks? At least that is what I think you want to know.
The answer is 318.13 grams.
Step-by-step explanation:
450 - 6.7% = 419.85 grams ---- End of week 1
419.85 - 6.7% = 391.72 grams ---- End of week 2
391.72 - 6.7% = 365.47 grams ---- End of week 3
365.47 - 6.7% = 340.98 grams ---- End of week 4
340.98 - 6.7% = 318.13 grams ------ End of week 5
Let's start his with some trigonometry
Cos60=x/30
X=15
Now we can use Pythagorean therom
15^2+b^2=30^2
B(y)= 25.98
