Which expression is equivalent to the given expression 4ln x + ln3 - ln x

Answer:

£263 = €299.82

€299.82 = $374.775

Answer:

374.78

Step-by-step explanation:

Essentially it would be 374.77 but it requires 2 decimal places so you have to round up to 78 and that's the answer hope it helps!

Answer: The unit rate for calories per cup = 96 calories

There are 288 calories in cups of the cereal.

Step-by-step explanation:

Given: Calories in [tex]\dfrac34[/tex]of cup =  72

Unit rate of calories per cup =  [tex]\dfrac{72}{\dfrac34}=\dfrac{72\times4}{3}[/tex]

= 96

The unit rate for calories per cup = 96

Calories in 3 cups = 3 x (unit rate for calories)

= 3 x (96)

= 288 calories

Hence, there are 288 calories in cups of the cereal.

Answer:

He will have 2.92 pounds of dog food left.

Step-by-step explanation: Subtract 2.83 from 5.75 and you will get this answer.. hope this helped:)!!

Answer:

2.92 pounds

Step-by-step explanation:

We are finding out how much we have left, so we're subtracting, so our equation is:

5.75 - 2.83 = 2.92

So, Julio will have 2.92 pounds of dog food left

Answer:

[tex]f(x) = x^{2} - 1[/tex]

Step-by-step explanation:

The definition of even function is: [tex]f(x) = f(-x)[/tex]

I am going to assume the  second option is [tex]f(x) = x^{2} - 1[/tex] and the answer.

[tex]f(x) = x^{2} - 1\\f(-x) = (-x)^{2} - 1 = x^{2}-1[/tex]

Answer:

Kindly check explanation

Step-by-step explanation:

Organizations like NASA who explore space and planets often have to deal with measurement of very long distances such as the one stated above. The Major challenge with the distance written in the format expressed above is the difficulty to read, state or use in mathematical calculations as it is too explicit. A more effective method is to express this distance in standard format and more suitable long distant units such as miles.

For instance;

880,000,000,000,000,000,000,000 kilometers could be expressed as in standard form as ;

8.8 * 10^23 km

Answer:

Area is 50 meters squared

Step-by-step explanation:

So you know that length = 10 meters and width is half of the length.

You need to make an equation to solve for width, 'W', using length, 'L'

W = L / 2

Now just plug in length

W = 10 /2 = 5

Since you know length and width now, you can solve for area

Area = W * L

Area = 5 * 10

Area = 50

Answer:

x =6    y = 5

Step-by-step explanation:

3y = 15

3/3     15/3

y= 5

-2x + 6(5) = 18

-2x + 30 = 18

        -30    -30

-2x = -12

-2/-2    -12/-2

x = 6

Answer:

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Step-by-step explanation:

a) Geometrically speaking, the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval by definition of secant line:

[tex]r = \frac{y(b) -y(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds of the interval.

[tex]y(a)[/tex], [tex]y(b)[/tex] - Function exaluated at lower and upper bounds of the interval.

If we know that [tex]y = 3\cdot x^{2}[/tex], [tex]a = 3[/tex] and [tex]b = 6[/tex], then the average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval is:

[tex]r = \frac{3\cdot (6)^{2}-3\cdot (3)^{2}}{6-3}[/tex]

[tex]r = 27[/tex]

The average rate of change of [tex]y[/tex] with respect to [tex]x[/tex] over the interval [tex][3,6][/tex] is 27.

b) The instantaneous rate of change can be determined by the following definition:

[tex]y' = \lim_{h \to 0}\frac{y(x+h)-y(x)}{h}[/tex] (2)

Where:

[tex]h[/tex] - Change rate.

[tex]y(x)[/tex], [tex]y(x+h)[/tex] - Function evaluated at [tex]x[/tex] and [tex]x+h[/tex].

If we know that [tex]x = 3[/tex] and [tex]y = 3\cdot x^{2}[/tex], then the instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] is:

[tex]y' = \lim_{h \to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{(x+h)^{2}-x^{2}}{h}[/tex]

[tex]y' = 3\cdot \lim_{h \to 0} \frac{2\cdot h\cdot x +h^{2}}{h}[/tex]

[tex]y' = 6\cdot \lim_{h \to 0} x +3\cdot \lim_{h \to 0} h[/tex]

[tex]y' = 6\cdot x[/tex]

[tex]y' = 6\cdot (3)[/tex]

[tex]y' = 18[/tex]

The instantaneous rate of change of [tex]y[/tex] with respect to [tex]x[/tex] at the value [tex]x = 3[/tex] is 18.

Answer:

56.25 pound of the coffee that costs $5 per pound is needed

18.75 pound of the coffee that costs $9 per pound is needed

Step-by-step explanation:

Let the number of pounds be x and y respectively

The total pounds is 75;

So;

x + y. = 75 •••••••(i)

Total cost of first type

9 * x = $9x

Total cost of second type;

5 * y= $5y

75 pound at $6 per pound; total cost of this is;

6 * 75 = $450

Thus;

9x + 5y = 450 ••••••••(ii)

From i, x = 75-y

Put this into ii

9(75-y) + 5y = 450

675 -9y + 5y = 450

4y = 675-450

4y = 225

y = 225/4

y = 56.25

x = 75 - y from i

x = 75-56.25

x = $18.75

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = [tex]2\pi r[/tex] , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. [tex]2\pi r=2.5[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\pi}[/tex]

[tex]\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m[/tex]

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters
