Can you please answer these questions clearly?

Let fix)= *+3, *20. Complete parts (a) through (d) below. The relationship between mammal body mass (M) measured in grams and resting heart rate (R) measured in beats per minute is R(M) = 1180M 4 . This relationship is to be interpreted in a statistical sense; it does not exactly predict resting heart rate. Complete parts (a) through (c) below. O c. Q (a) Professor R.'s dog Molly weighs 24 kg. Predict Molly's heart rate from the formula for R(M). The heart rate is 95 beats per minute. (Round to the nearest whole number as needed. (b) Find the range of ((x) (b) Professor R. weighs 77 kg. Predict his heart rate from the formula for R(M). The range is 2. The heart rate is 71 beats per minute. (Simplify your answer. Type your answer in interval notation.) Round to the nearest whole number as needed. (6) For which values of x is fix)= ? (@) reality, Molly's resting heart rate is about 45 beats per minute, and Professor R.'s heart rate is about 65 beats per minute. Calculate the relative error from using the heart beat formula. The formula for relative error is freal heart beat rate - predicted hea predicted heart beat rate (Smelly your answer. U were as needed.) The relative error for Molly's heart rate is Round to three decimal places as needed.) Let NX) = ..2. *20. Complete parts (a) through (c) below OA Right (C) y= X+ 1 or y axis or down Left x axis up or Oc Q Shift y = = [unit(s) reflect about the and then shift unit(s). (Type whole numbers.) (bj On the basis of the graph in (a), find the range of fix). he range is Simpify your answer. Type your answer in interval notation.) number of different languages arent languages spoken by the people ocean agua occupying that region. city: Specifically, if A is the area of a region measured in km? and D is the D =0.24042 Use the given formula to complete parts (a) and (b) below. (a) Estimate from this formula the number of languages spoken in the United States (area: 9.857 x 10 km?).
