-5(7x-9)-6=144 what is the answer.
Answer: x= -3
Step-by-step explanation:
Answer:
x=-3
Step-by-step explanation:
First you must start by multiplying the parentheses by -5. Once you do that, your equation comes out to -35x+45-6=144. Then you must combine like terms which comes out to -35x+39=144. After that you must get x by itself, so to do that subtract 39 from 144 which comes out to 105. Then you must do the opposite of multiplication and divide 105 by -35 which comes out to x=-3. Hope this helps

If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B? 1.The range of set A is greater than the range of set B. 2. Sets A and B are both evenly spaced sets.
Step-by-step explanation:
(1) The range of set A is greater than the range of set B.
This statement gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10
Clearly, Former one has higher range but lower standard deviation.
(2) Sets A and B are both evenly spaced sets.
Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.
For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or, we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.
Solve the initial value problem: y(x) = dy dx || -0.8 cos(y)' y(0) = K|4
The solution of the given initial value problem is x + ln|K/4 + 0.8sin(K/4)|
The given initial value problem is:y(x) = dy/dx - 0.8cos(y).....(1)y(0) = K/4
We are to find the solution of this initial value problem.
Step 1: Separating the variables:Separating the variables in equation (1), we get:dy / (y + 0.8cos(y)) = dx.....(2)
Step 2: Integrating both sides:Integrating both sides of equation (2), we get:∫ dy / (y + 0.8cos(y)) = ∫ dxOr, ln|y + 0.8sin(y)| = x + c_1 , where c_1 is the constant of integration.
Step 3: Applying initial condition:Given that y(0) = K/4, we have:ln|K/4 + 0.8sin(K/4)| = 0 + c_1Or, c_1 = ln|K/4 + 0.8sin(K/4)|
The solution of the given initial value problem is:ln|y + 0.8sin(y)| = x + ln|K/4 + 0.8sin(K/4)|

TRUE / FALSE. when the block is in equilibrium, each spring is stretched an additional ∆x. then the block is set into oscillation with amplitude a; when it passes through its equilibrium point it has a speed v.
The statement is true.
When the block is in equilibrium, each spring is stretched an additional ∆x. This implies that the forces from the two springs are balanced, and the block is not experiencing any net force in the equilibrium position.
When the block is set into oscillation with amplitude a, it will pass through its equilibrium point during the oscillation. At the equilibrium point, the displacement of the block is zero, and it changes direction. At this point, the block has its maximum speed v, as it is accelerating towards the equilibrium position.
The speed of the block decreases as it moves away from the equilibrium position, reaches zero at the maximum displacement (amplitude), and then starts accelerating towards the equilibrium point again. Therefore, when the block passes through its equilibrium point, it has its maximum speed v.

Where the above are given,
10. The nurse should give 2.45ml of the liquid medication.
11. The nurse can give 24ml of meperidine in 24 hours.
12. The patient should take 42 tablets of the antibiotic.
13. The IV rate is 100ml/hr at 1500gtt/min with a 15gtt/ml drip factor.
14. Each dose of codeine contains 15000mg.
15. The patient should be given 2.67oz (approximately) of the cough syrup.
What is the explanation for the above ?10. To determine how much of the liquid should be given, we can set up a proportion
1g/3.5ml = 700mg/x
Cross-multiplying,
1g * x = 700mg * 3.5ml
x = (700mg * 3.5ml) / 1g
x = 2450mg*ml/g
Therefore, the amount of liquid to be given is 2.45ml.
11. The order states meperidine 75mg IM every 6 hours PRN pain, and the pharmacy sends a vial that contains 25mg/2ml. To calculate how many ml can be given in 24 hours, we need to consider the frequency and duration.
In 24 hours, there are 24/6 = 4 doses to be given. Each dose contains 75mg of meperidine.
To find the volume (ml) of each dose, we can set up a proportion -
25mg/2ml = 75mg/x
25mg * x = 75mg * 2ml
x = (75mg * 2ml) / 25mg
x = 6ml
12. To calculate the number of tablets the patient should take, we need to consider the dosage and the duration.
Each tablet contains 250mg of the antibiotic.
To find the number of tablets for the total dosage, we can set up a proportion -
250mg/1 tab = 0.75g/x
250mg * x = 0.75g * 1 tab
x = (0.75g * 1 tab) / 250mg
x = 0.003 tab
Since we cannot take a fraction of a tablet, the patient should take 1 tablet every 4 hours for 7 days, resulting in a total of 1 * 6 * 7
= 42 tablets.
13. To determine the IV rate, we need to calculate the number of drops per minute.
The formula to calculate the IV rate in drops per minute (gtt/min) is -
IV rate (ml/hr) = Total volume (ml) / Total time (hr)
IV rate (gtt/min) = IV rate (ml/hr) * Drop factor (gtt/ml)
IV rate (ml/hr) = 1000ml / 10hr = 100ml/hr
IV rate (gtt/min) = 100ml/hr * 15gtt/ml =
1500gtt/min
Therefore, the IV rate is 100ml/hr at 1500gtt/min.
14. To determine the amount of milligrams of codeine in each dose, we need to convert grams to milligrams.
1 gram (g) = 1000 milligrams (mg)
15 grams (gr) = 15 * 1000mg = 15000mg
Therefore, each dose contains 15000mg of codeine.
15. To calculate how much cough syrup should be given in ml's, we can set up a proportion -
225mg/1oz = x ml/600mg
225mg * x = 1oz * 600mg
x = (1oz * 600mg) / 225mg
x = 2.67oz
Therefore, 2.67oz of cough syrup should be given in ml's.

The laundry has been sorted into dark clothes and light clothes. The number of dark clothes is three more than twice the number of light clothes. The laundry is 60% dark clothes. Choose the equation that best represents this scenario. x over quantity 2x plus 3 equals 40 over 60 x over quantity 2x plus 3 equals 60 over 40 x over quantity 2x plus 3 equals 40 over 100 x over quantity 2x plus 3 equals 60 over 100
Answer:
x over quantity 2x plus 3 equals 40 over 60
Step-by-step explanation:
Let light clothes=x
Number of dark clothes = 2x + 3,
Dark clothes are 60% of total clothes
Light clothes=100%-60%
=40%
Light clothes / dark clothes = percentage of light clothes / percentage of dark clothes
x / 2x+3 = 40 / 60
x over quantity 2x plus 3 equals 40 over 60
Expression for this situation will be \(\frac{x}{2x+3}=\frac{60}{40}\).
Let the number of dark cloths = y
And the number of light cloths = x
"The number of dark cloths is three more than twice the number of light cloths".
Therefore, equation will be,
y = 2x + 3 ----- (1)
"The laundry is 60% dark cloths"
Equation for this statement will be,
y = \(\frac{60}{100}(x+y)\)
y = 0.6x + 0.6y
y - 0.6y = 0.6x
0.4y = 0.6x
\(\frac{y}{60}=\frac{x}{40}\)
Now substitute the value of y from equation (1),
\(\frac{2x+3}{40}=\frac{x}{60}\)
\(\frac{2x+3}{x}=\frac{40}{60}\)
\(\frac{x}{2x+3}=\frac{60}{40}\)
Therefore, expression for this situation will be \(\frac{x}{2x+3}=\frac{60}{40}\).

What is volume?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected. The space occupied inside an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity. An object's volume is the amount of space it occupies. Cubic meters are used to measure large quantities (m3). Cubic centimeters (cm3) or cubic millimeters are used to measure smaller quantities (mm3).
Here,
V=x²h
128=x²h
h=128/x²
A=x²+4xh
=x²+4x(128/x²)
=x²+512/x
A'=2x-512/x²
A'=(2x³-512)/x²
A'=0
2x³=512
x³=256

An office is planning to divide a common area into a social area and a quiet area. The quiet area takes up one-third of the space. The architect draws this plan at a scale of 1 ft.: 4 cm. What is the area of the social area on the plan?
Answer:
Let's call the total area of the common space "A". Since the quiet area takes up one-third of the space, its area is A/3.
The scale of the plan is 1 ft.: 4 cm, which means that one foot on the plan represents 4 cm in real life. So, the area of the social area on the plan is 4 times smaller than the actual area of the social space.
Therefore, the actual area of the social space is (A - A/3) = 2A/3. And the area of the social area on the plan is (2A/3) / 4.
Area of the social area on the plan is (2A/3) / 4.

B. f x
(x,y)=−3ye −3x
C. f x
(x,y)=−3ye −3xy
D. f x
(x,y)=−3(x+y)e −3xy
The value of f_x(x,y) is -3ye^{-3xy}(B)
The function is f(x,y) = e ^{-3xy}.
Let us find f_x(x,y) which is the partial derivative of the function with respect to x. For that, let us differentiate the function f(x,y) with respect to x taking y as constant.
This is because the given function is in terms of two variables x and y. We can differentiate one variable at a time and treat the other variable as constant.
Hence we will differentiate the function in terms of x and treat y as a constant.
f(x,y) = e^{-3xy}
∴ f_x(x,y) = \frac{\partial }{\partial x}
f(x,y)f_x(x,y) = \frac{\partial }{\partial x} e^{-3xy}
Now let us differentiate the above expression which is a single variable function using the chain rule of differentiation. The chain rule of differentiation states that if f(g(x)) is a composite function of x, then the derivative of f(g(x)) is given by
f'(g(x)) * g'(x)
We have f(x) = e^{x} and
g(x) = -3xy
∴ f'(g(x)) = e^{g(x)} and g
'(x) = \frac{\partial }{\partial x}(-3xy)
= -3y
We can use the chain rule to differentiate f(g(x)) as follows:
f_x(x,y) = e^{-3xy} * \frac{\partial }{\partial x}(-3xy)f_x(x,y)
= -3y * e^{-3xy}
Hence the value of f_x(x,y) is -3ye^{-3xy}.Hence the correct option is B.

5 hours after noon, darmian is 17 miles closer to the stadium than paisley
Step-by-step explanation:
At noon, Damian is 383 miles away from the stadium and paisley is 315 miles away from the stadium.
Now, we are told that damians speed is 59 mph while paisley's speed is 42 mph.
At t hours after noon, their distance covered will be;
Damian; D = 59t
Paisley; P = 42t
This is because distance = speed × time
Now, 5 hours after noon, their respective distance covered will be;
D(5) = 59 × 5 = 295 miles
P(5) = 42 × 5 = 210 miles
This means that;
distance of Damian from the stadium is; 383 - 295 = 88 miles
Distance of paisley from the stadium is;
315 - 210 = 105 miles
Difference in their distances to the stadium = 105 - 88 = 17 miles
Thus, 5 hours after noon, darmian is 17 miles closer to the stadium than paisley
