What are exponential expressions?

Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied.

The exponential expression is given in the question, as follows:

[tex]p^\frac{11}{5}[/tex]

We have to determine the equivalent expression to the given expression.

As per option (C), we have

⇒ ⁵√p¹¹

The above expression also can be written as:

⇒ [tex](p^{11})^\frac{1}{5}[/tex]

⇒ [tex](p^{11})^{\times}{(\frac{1}{5})}[/tex]

⇒ [tex]p^\frac{11}{5}[/tex]

Hence, we can conclude that the expression ⁵√p¹¹ is equivalent to the given expression.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The position of Allien in the coordinate plane is (0,5), the coordinate of the rocket is (5,0). The slope between the two  is,

Slope, m = (0 - 5)/(5 - 0) = -5/5 = -1

The equation of the line can be written as,

y = -1x + C

substitute any one of the point in the equation,

0 = -1(5) + C

0 = -5 + C

C = 5

Hence, the equation of the line is Y=-x+5. Thus, the correct option is C.

Which trigonometric functions have the same maximum value?

y = arcsinx and y = arctanx
y = arctanx and y = arcsecx
y = arccosx and y = arcsecx

Answers

Answer:

D.  y = arccosx and y = arcsecx

Step-by-step explanation:

Answer:

The trigonometric function which have the same maximum value is:

y = arcsinx and y = cos x

Concept:

What are Inverse trigonometric functions?

Inverse trigonometric functions are represented as arcsinx, arccosx, arcsecx, and so on.

The trigonometric functions that are used to calculate an angle from any of the angle's trigonometric ratios are called inverse functions.

The formula which is used to in inverse  trigonometric equations are:

arcsinx = -arcsinx

arccosx = pi-arccosx

arctanx = -arctanx

arcsecx = pi - arcsecx

Solution:

The maximum values we obtain from the following equations are:

arcsinx = -1 to 1

arccosx = -1 to 1

arctanx = -pi/2 to pi/2

arcsecx = ∞

So the trigonometric functions which have the same maximum value is arcsinx and arccosx.

Sally wants to start a small business. She plans to sell snack packs by re-packing cookies and coffee sachets. Cookies come in packs of 10, while 3-in-1 coffee sachets come in packs of 12.
What is the smallest number of packs for each item should Sally buy if she wants to have packs with 1 cookie and 1 coffee sachet?

Answers

Answer: She needs 6 packs of cookies and  5 packs of coffee sachets.

Step-by-step explanation:

Cookies: come in packs of 10

Coffee sachets: come in packs of 12.

Sally wants to sell them in groups of 1 cookie and 1 coffee sachet, then we need to find a common multiple of 10 and 12. (the smallest one in this case).

To find the smallest common multiple, first let's find the largest common factor between 10 and 12.

If we write the numbers as a product of prime numbers, we have:

10 = 2*5

12 = 2*3*3

The only common factor is 2.

Then the smallest common multiple between 10 and 12 is equal to the product of 10 and 12 divided by the largest common factor between them, in this case is 2.

M = 10*12/6 = 60

Now to find the number of packages of each thing that she must buy, we need to divide 60 by the number of elements in each pack.

Cookies: 10 per pack

60/10 = 6

She needs 6 packs of cookies

Coffe: 12 per pack

60/12= 5

She needs 5 packs of coffee sachets.
