Answer:

Step-by-step explanation:

If it was like....[tex]\frac{a^{5}}{a^{3}}[/tex]

then you subtract 5 minus 3 to be left with a^2 on the numerator

That would be how you would take it away.

Answer:

His daily dosage is 199.6 mg divided in four doses of 49.9 mg. The Nurse needs to draw 2.495 mL from a medicine that comes in 100mg/5mL.

Step-by-step explanation:

To calculate the daily dose we first need to find the mass of the Patient in kg. To do that we need to divide his weigh in lbs by 2.205.

[tex]weigh = \frac{22}{2.205} = 9.98 \text{ kg}[/tex]

Since he needs to take 20 mg of drug per kg of body in a day, we need to multiply his weigh by this dosage:

[tex]\text{daily dosage} = 9.98*20 = 199.6 \text{ mg}[/tex]

Each individual dose must be [tex]\frac{1}{4}[/tex] of his daily dose, so:

[tex]\text{each dose} = \frac{199.6}{4} = 49.9 \text{ mg}[/tex]

Since the medicine comes in 100mg /5 mL, the nurse needs:

[tex]\text{volume of dose} = \frac{49.9}{100}*5 = 2.495 \text{ mL}[/tex]

Answer:

[tex]128[/tex]

[tex]2 {}^{4} \times ( \frac{1}{2 {}^{2} } ) \times 2 {}^{5} = 128 \\2 {}^{9} \times ( \frac{1}{2 {}^{2} } ) \\ 512 \times ( \frac{1}{4} ) \\ \frac{512}{4} \\ 128[/tex]

The simplified value of the given exponential expression is  [tex]\frac{1}{2^{2} }[/tex].

"Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor."

The given expression is:

[tex](2^{4})(2^{3})/(2^{5})(2^{4} )\\= 2^{4+3}/2^{5+4}\\= 2^{7}/2^{9} \\= 2^{7-9}\\= 2^{-2} \\= \frac{1}{2^{2}}[/tex]

Answer:

b.             x = -y2 + 2y + 5

Step-by-step explanation:

Eliminate answers a and d because neither has a negative sign (the negative sign is the reason the graph opens to the left).

Check out answer b.  Suppose y = 1.  Then x = -(1)^2 + 2(1) + 5 = 6.  

This point (6, 1) satisfies equation b and corresponds to the right-most point on the graph.

Answer:

[tex]y=\frac{9}{2}\cos \left(\frac{4}{3}x+\frac{2\pi }{3}\right)+\frac{1}{2}\\\\Or\\\\y=4.5\cos \left(1.33x+0.67\pi \right)+0.5[/tex]

Answer:

V = 3591.4 cm³

Step-by-step explanation:

Volume of Sphere = [tex]\frac{4}{3} \pi r^3[/tex]

Where r = 9.5 cm

V = [tex]\frac{4}{3} (3.14)(9.5)^3[/tex]

V = [tex]\frac{4}{3} (3.14)(857.4)[/tex]

V = [tex]\frac{10774}{3}[/tex]

V = 3591.4 cm³

Answer:

[tex]3591.4{cm}^{3} [/tex]

Step-by-step explanation:

[tex]v = \frac{4}{3} \pi {r}^{ 3} \\ = \frac{4}{3} \times \pi \times 9.5 \times 9.5 \times 9.5 \\ = 3591.4 \\ [/tex]

Answer:

3√2

Step-by-step explanation:

Pythagoras says s²+s²=6²

so

2s² = 36

s = √18 = √9·2 = √3²·2 = 3√2

Answer:

C

Step-by-step explanation:

The diagonal splits the square into 2 right triangles with hypotenuse 6

Using Pythagoras' identity in one of the right triangles.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

s² + s² = 6²

2s² = 36 ( divide both sides by 2 )

s² = 18 ( take the square root of both sides )

s = [tex]\sqrt{18}[/tex] = [tex]\sqrt{9(2)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex] → C

Step-by-step explanation:

We have the product of two expressions. The product is equal to 0 if and only if one of the factors is equal to 0.

Therefore

[tex](i)\\(x+3)(x-4)=0\iff x+3=0\ \vee\ x-4=0\\\\\boxed{x=-3\ \vee\ x=4}\\\\(ii)\\(2x-3)(x-1)=0\iff2x-3=0\ \vee\ x-1=0\\\\\boxed{x=1.5\ \vee\ x=1}[/tex]

Answer:

y = √(x - 4)

Step-by-step explanation:

To find the inverse, simply swap x and y in your equation, then solve for in terms of y. Keep in mind that this isn't the true inverse of y = x² + 4 because y = √(x - 4) has a restricted domain.

Answer:

B. y = √(x - 4)

Answer:

-7x-1

Step-by-step explanation:

6-(9x+7)+2x

-(9x+7): -9x-7

= 6-9x-7+2x

6-9x-7+2x=-7x-1

-7x-1

Answer:

-7x - 1

Step-by-step explanation:

Well to start off we have to multiply because of the - symbol at the start of the parenthesis.

So - * 9x is -9x and - * 7 is -7 so our equation looks like this now [tex]6-9x-7+2x=[/tex].

Now we have to combine like terms so 6 + -7 is -1 and -9x + 2x is -7x.

So now our equation looks like this [tex]-7x-1=[/tex].

So that is simplifued all the way.

Answer:

3.21%

Step-by-step explanation:

The panel is measured to be 16.25 in by 8.13 in.

The actual plan shows that the panel is supposed to have an area of [tex]128$ in^2[/tex].

We are to determine the percentage error in the area of the panel.

[tex]\text{Percentage Error}=\dfrac{\text{Wrong Value-Actual Value}}{\text{Actual Value}} \times 100[/tex]

Wrong Area of the Panel = 16.25 X 8.13 =[tex]132.1125$ in^2[/tex]

Actual Area = [tex]128$ in^2[/tex].

[tex]\text{Percentage Error}=\dfrac{132.1125-128}{128} \times 100\\=\dfrac{4.1125}{128} \times 100\\=3.21\%[/tex]

The percentage error in the area of the panel is 3.21%.

Answer:

n is equal to 17 if you want you can plug the number to both equation and try to see if both are equal if they are equal that means you did it right

Answer:

n = 17

Step-by-step explanation:

The opposite angles of a Parallelogram are equal.

So,

4n-2 = 2n+32

4n-2n = 32+2

2n = 34

Dividing both sides by 2

n = 17
