Answer:you need to multiply it by 4.
Step-by-step explanation:
If the number is multiplied by 4 it square root is effectively doubled.
Example: if you take the square root of 64, its 8.
to double the square root, you multiply 64 by 4---> 256.
And the square root of 256, is 16, double that of the square root of 64.

solve the inequality 9(x/3+1) > 6
Answers
Step-by-step explanation:
On solving the inequality, we get the solution inequality as -
x > -1.
What is a Inequality? What is equation modelling? What is a mathematical equation and expression?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.
Given is the inequality -
9(x/3 + 1) > 6
The given inequality is -
9(x/3 + 1) > 6
(x/3 + 1) > (6/9)
(x/3 + 1) > 2/3
x/3 + 1 - 1 > 2/3 - 1
x/3 > (2 - 3)/3
x/3 > -1/3
x > -1
Therefore, on solving the inequality, we get the solution inequality as -
x > -1.

A Fahrenheit thermometer shows that the temperature is 15 degrees below zero. Enter the integer that represents the temperature in degrees Fahrenheit.
Answers
Answer:
The integer that represents 15 degrees below 0 is -15°F.
Step-by-step explanation:
This is because the phrase "15 degrees below 0" is obviously not an integer meaning that the corresponding integer to this phrase would be -15.
The thermometer shows - 15°F the temperature is 15 degrees below zero.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit.
Given, A Fahrenheit thermometer shows that the temperature is 15 degrees below zero.
So, If we assume the thermometer as a number line it is 15 units left to the origin.
∴ (0 - 15)°F.
= - 15°F.

Solve for x: 2x^5/3-22=464 a) x = 28 b) x = 27 c) x = ±27 d) x = ±28
Answers
Answer:
x = 27Step-by-step explanation:
Given the expression [tex]{2x^{\frac{5}{3} }-22 = 464[/tex], we are to find the value of x in the expression. This is as shown below;
[tex]{2x^{\frac{5}{3} }-22 = 464[/tex]
add 22 to both sides
[tex]{2x^{\frac{5}{3} }-22 = 464+22\\\\[/tex]
[tex]{2x^{5/3} =486[/tex]
divide both sides by 2
[tex]\frac{2x^{5/3}}{2} =\frac{486}{2}\\ x^{5/3} = 243[/tex]
raise both sides to the power of 3/5
[tex](x^{5/3})^{3/5} = (243)^{3/5}\\x = (\sqrt[5]{243}) ^3\\x = 3^3\\x = 27[/tex]

A nurse is preparing to administer dopamine 2 mcg/kg/min by continuous IV infusion for a client who weighs 110 lb. Available is dopamine
400 mg in 250 mL of D5W. The nurse should set the IV pump to deliver how many ml/hr administer? (Round the answer to the nearest
tenth.)
Answers
Answer:
3.7ml/hr
Step-by-step explanation:
From the question
A nurse is preparing to administer dopamine 2 mcg/kg/min by continuous IV infusion
Step 1
The patient weighs 110lb(pounds
Convert the patients weight to kilogram
1 lb = 0.454kg
110lb =
Cross Multiply
110lb × 0.454kg
= 49.94kg
The patient weight = 49.94kg
Step 2
The dosage to to be administered by the nurse = 2 mcg/kg/min
If 1 kg = to be administered 2mcg/min
49.94 kg =
(49.94kg × 2mcg/min)/1
= 99.88mcg/min
Therefore, for the patient's body weight, the patient's dosage = 99.88mcg/min
Step 3
Available dopamine is 400mg in 250ml
We have to convert this to mcg
Hence,
1 mg = 1000mcg
400mg =
Cross Multiply
= 400mg × 1000mcg
= 400000mcg
Hence, the available dopamine is administer in 250ml/400000mcg
Part 3
Since 60 minutes is 1 hour
The nurse should set the IV pump to deliver how many ml/hr
(99.88mcg/min × 250ml × 60mins)/ 400000mcg
= 3.7455ml/hr
Approximately to the nearest tenth = 3.7ml/hr
1200-5(3x+30)=600 show the steps to solve this problem
Answers
Answer:
x=+30
Step-by-step explanation:
1200-5(3x+30)=600
We move all terms to the left:
1200-5(3x+30)-(600)=0
We add all the numbers together, and all the variables
-5(3x+30)+600=0
We multiply parentheses
-15x-150+600=0
We add all the numbers together, and all the variables
-15x+450=0
We move all terms containing x to the left, all other terms to the right
-15x=-450
x=-450/-15
x=+30
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 30}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{1200 - 5(3x + 30) = 600}[/tex]
Distribute 5 through the parentheses
[tex] \dashrightarrow{ \sf{1200 - 15x - 150 = 600}}[/tex]
Subtract the numbers: 150 from 1200
[tex] \dashrightarrow{ \sf{ - 15x + 1050 = 600}}[/tex]
Move 1050 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{ - 15x = 600 - 1050}}[/tex]
Subtract 1050 from 600
[tex] \dashrightarrow{ \sf{ - 15x = 450}}[/tex]
Divide both sides of the equation by -15
[tex] \dashrightarrow{ \sf{ \frac{ - 15x}{ - 15} = \frac{ - 450}{ - 15} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = 30}}[/tex]

f(x) = (2x + 1)(x - 2)(x + 3)
Answers
Answer:
f(3) = 42.
Y-intercept is (0, -6).
X-intercepts are (-0.5, 0), ( 2, 0) and (-3, 0).
Step-by-step explanation:
f(3) = (2(3) + 1)(3 - 2)(3 + 3)
= 7 * 1 * 6
= 42.
The y intercept occurs when x = 0:
y-intercept = (2(0) + 1)(0 - 2)(0 + 3)
= 1 *-2*3
= -6.
Calculate the x-intercepts:
(2x + 1)(x - 2)(x + 3) = 0 so
(2x + 1) = 0 or (x - 2) = 0 or (x + 3) = 0
So x = -0.5, 2 or -3.
