Answer: 7

Step-by-step explanation:

Given : The recommended daily allowance for vitamin c is 60 mg per day .

Then, for one whole week , the recommended allowance for vitamin c will be :-

$7\times60=420\text{ mg}$

Also, there are 70 mg of vitamin C per 100 g orange.

1 g = 1000 ml

The proportion of Vitamin C in 100 g = $\dfrac{70}{100000}=0.0007$

1 oz =28.3495 grams

Then, $3\ oz= 3\times28.3495=85.0485 \text{ gm}=85048.5\ mg$

Then, amount of vitamin C in 85048.5 mg = $0.0007\times85048.5=59.53395\approx59.53\ mg$

Then, the number of oranges have to eat each week to meet this requirement= $\dfrac{420}{59.53}\approx7$

Hence, about 7 oranges you would have to eat each week to meet this requirement.

I need step by step instructions on how to get the y-intercept: -210 for f(x)=x^3-18x^2+107x-210.

Mrrafil [7]

Y=f(X)
At y-intercept, X=0
f(X)= 0^3-18(0)^3+107(0)-210
= -210
