Which sentence can represent the inequality 2.4 (6.2 minus x) greater-than negative 4.5?

-BARSIC- [3]

Answer: Choice B

Two and four tenths multiplied by the difference of six and two tenths and a number is more than negative four and five tenths.

======================================================

Explanation:

2.4 = 2 + 0.4

2.4 = 2 and 4/10

2.4 = 2 and 4 tenths

2.4 = two and four tenths

-------------------

Through similar reasoning,

6.2 = six and two tenths

And also,

-4.5 = negative four and five tenths

---------------------

Notice how 6.2 - x translates into "difference of six and two tenths and a number"

We then multiply that by 2.4, aka two and four tenths.

So that's how we get the phrasing "Two and four tenths multiplied by the difference of six and two tenths and a number"

All of this is greater than -4.5 aka negative four and five tenths.

This points us to Choice B as the final answer.

A quadratic function is given. f(x) = 1 + x − 7 x2 (a) Use a graphing device to find the maximum or minimum value of the quadrat

Virty [35]

Answer:

a) $P (x,y) \approx (0.1,1.05)$ , b) $P(x,y) = (0.07,1.04)$ .

Step-by-step explanation:

a) The graphic is enclosed to the problem. By visual inspection, an absolute maximum is found.

$P (x,y) \approx (0.1,1.05)$

b) The exact method consists in the application of the First and Second Derivative Tests. First and second derivatives are, respectively:

$f'(x) = 1 - 14\cdot x$

$f''(x) = -14$

The First Derivative Test consists in equalizing the first derivative to zero and solving the expression:

$1 - 14\cdot x = 0$

$x = 0.07$

According to the second derivative, the critical point leads to a maximum. The remaining component is determined by evaluation the polynomial:

$y = 1 +0.07-7\cdot (0.07)^{2}$

$y = 1.04$

The exact solution is $P(x,y) = (0.07,1.04)$ , indicating that graphic solution leads to a good approximation.

104 pounds requires 156 milligrams of medicine what is the weight of a patient who requires 207 milligrams of medicine

Lubov Fominskaja [6]

Answer:

138 pounds

Step-by-step explanation:

Let the required weight of the patient be x pounds.

We have that,

156 milligrams of medicine is required for a patient weighing 104 pounds.

Then, 207 milligrams of medicine will be required for a patient having weight as shown below,

Weight of the patient = $\frac{104 \times 207}{156}$

i.e. x = $\frac{21528}{156}$

i.e. x = $138$

Hence, the patient needing 207 milligrams of medicine will have the weight 138 pounds.
