stacie is a resident at a medical facility you work at. You are asked to chart the amount of solid food that she consumes.For the noon meal today, she ate 1/2 of a 3 ounce serving of meatloaf, 3/4 of her 3 ounce serving of mashed potatoes, and 1/3 of her 2 ounce serving of green beans. Show in decimal form how many ounces of solid food that Stacie consumed
I've been struggling with this because of how close the numbers are together!! I would really appreciate if someone could help me❤️
Matrix MЄ R4×4, as specified below, is an orthogonal matrix - thus, it fulfills MTM = I.
M
(ELES),-
m2,1.
We know also that all the six unknowns mr,c are non-negative with the exception of
Your first task is to find the values of all the six unknowns. Think first, which of the mr,c you should find first.
Next, consider a vector v = (-6, 0, 0, 8) T. What's the length of v, i.e., |v|?
Using M as transformation matrix, map v onto w by w = Mv provide w with its numeric values.
What's the length of w, especially when comparing it to the length of v?
Finally, consider another vector p = ( 0, 0, 8, 6) T. What's the angle between v (from above) and p?
Using M as transformation matrix, map p onto q by q = Mp - provide q with its numeric values.
What's the angle between w and q, especially when comparing it to the angle between v and p?

- Compare the interest earned from #1 (where simple interest was used) to #5 (where compound interest was used). The principal, annual interest rate, and time were all the same; the only difference was that for #5, interest was compounded quarterly. Does the difference in interest earned make sense? Select one of the following statements. a. No, because more money should have been earned through simple interest than compound interest. b. Yes, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. c. No, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. d. Yes, because more money was earned when compounded quarterly. For compound interest you earn interest on interest, not just on the amount of principal.arrow_forwardCompare and contrast the simple and compound interest formulas. Which one of the following statements is correct? a. Simple interest and compound interest formulas both yield principal plus interest, so you must subtract the principal to get the amount of interest. b. Simple interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest; Compound interest formula yields only interest, which you must add to the principal to get the final amount. c. Simple interest formula yields only interest, which you must add to the principal to get the final amount; Compound interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest. d. Simple interest and compound interest formulas both yield only interest, which you must add to the principal to get the final amount.arrow_forwardSara would like to go on a vacation in 5 years and she expects her total costs to be $3000.
