Is y=-4+3x^2 maximum of minimum
mixer [17]

Answer:

minimum

Step-by-step explanation:

Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0

Whether the function is maximum or minimum can be determined by consideration of the sign of the coefficient a

• If a > 0 then minimum

• If a < 0 then maximum

For y = - 4 + 3x² the value of a is 3 > 0

Hence y = - 4 + 3x² is a minimum

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed
shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168  pounds

Patient's weight in kg =168\times 0.453592=76.203456  kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = 0.4 \times 76.2035\ mg = 30.4814\ mg

We know,  1 micro gram = 0.001 mg

Concentration of drug is given by,

500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

d= \frac{30.4814}{0.5} = 60.9628

Therefore, We inject 60.9628 milliliters of dosage.

CAN SOMEBODY PLEASE HELP ME?!
AleksAgata [21]

Answer:

y - 18 = -1.5(x - 12)

Step-by-step explanation:

A = (12, 18)

B=(1.25(12), 0.75(18)) = (15, 13.5)

 

Find slope:  m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5

 

Point slope form:  y - y1 = m(x - x1)

Using point A as (x1, y1)

 

y - 18 = -1.5(x - 12)

Simplify"<br>2x² + 16x + 14 / X² - 1​
Phoenix [80]

Answer:  16x+3+x214​

Step-by-step explanation:

Multiply 2 and 2 to get 4.

4+16x+x214​−1

Subtract 1 from 4 to get 3.

3+16x+x214​

To add or subtract expressions, expand them to make their denominators the same. Multiply 3+16x times x2x2​.

x2(3+16x)x2​+x214​

Since x2(3+16x)x2​ and x214​ have the same denominator, add them by adding their numerators.

x2(3+16x)x2+14​

Do the multiplications in (3+16x)x2+14.

x23x2+16x3+14​
