If ab = c - d, which of the following is an expression for d in terms of a, b, and c?
horsena [70]
ANSWER

d =  - ab + c


EXPLANATION


The given expression is

ab = c - d

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.


This means that, we need to isolate d on one side of the equation while all other terms are on the other side.



We subtract from both sides of the equation to obtain,


ab - c = - d



We now divide through by -1, to get,



- ab  +  c = d


Or


d = - ab  +  c

A person x inches tall has a pulse rate of y beats per​ minute, as given approximately by yequals600 x Superscript negative 1 di
tankabanditka [31]

Answer:

a) 5.13beats/min

b) 2.82 beats/min

Step-by-step explanation:

Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75

If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;

y = 600(39)^-1/3

y = {600(1/39)}/3

y = 600/39×3

y = 600/117

y ≈ 5.13beats/min

The instantaneous rate for a 39 inches tall person is 5.13 beats per min

b) For a 71inches tall person, the beat rate will be expressed as;

y = 600(71)^-1/3

y = {600(1/71)}/3

y = 600/71×3

y = 600/213

y ≈ 2.82 beats per minute

The instantaneous rate for a 71 inches tall person is 2.82 beats per min

30 yd wide and 50 yd long find the length of the diagonal
Troyanec [42]
It's the same as finding the hypothenuse of a right triangle. Let c be the hypothenuse.

30 squared+ 50 squared= c squared.

900+ 2500= c squared
3400= c squared

Then find the square root of 3400 and that will equal c.

So, depending in what form the teacher was the answer. The answer will be square root of 3400 ft squared or 58.3 ft squared.
