Dr. mann mixed 10.357 g of chemical a 12.062 g of chemical b and 7.506 g of chemical see to make five doses of medicine

Part a) The estimate amount of medicine is 30.0 grams

Part b) The actual amount of medicine is 29.925 g. The difference between the  estimate and the actual amount, is 0.075 g

Part c) 5.985 grams

Part d) 6 grams

Step-by-step explanation:

The complete question is

Dr. Mann mixed 10.357 g of chemical A, 12.062 g of chemical B, and 7.506 g of chemical C to make 5  doses of medicine.

a. About how much medicine did he make in grams? Estimate the amount of each chemical by  rounding to the nearest tenth of a gram before finding the sum. Show all your thinking.

b. Find the actual amount of medicine mixed by Dr. Mann. What is the difference between your  estimate and the actual amount?

c. How many grams are in one dose of medicine? Explain your strategy for solving this problem.

d. Round the weight of one dose to the nearest gram

Part a) round  to the nearest tenth of a gram first

Chemical A

10.357 g > 10.4 g

Chemical B

12.062 g > 12.1 g

Chemical C

7.506 g > 7.5 g

To find out the estimate amount of medicine sum the three values

10.4+12.1+7.1=30.0 g

therefore

The estimate amount of medicine is 30.0 grams

Part b)

The actual amount of medicine is

10.357+12.052+7.506=29.925 g

To find out the difference between your  estimate and the actual amount, subtract the actual amount from the estimate

30.0-29.925=0.075 g

Part c) To find out how many grams are in one dose of medicine, divide the actual amount of medicine by five

29.925 g/5=5.985 g

Part d) Round the weight of one dose to the nearest gram

we have

5.985 g > 6 g

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
