So the change of rate of x is -1/3 .

The Derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.

Given that object is decreasing at constant rate of 2 units per second so we have [tex]y = 2x^2 + 1[/tex]

[tex]\frac{dy}{dt} = 4x \frac{dx}{dt}[/tex]

given dy/dt = -2

when x = 3/2

-2 = 4(3/2) dx/dt

-2 = 6 dx/dt

dx/dt = -2/6

         = -1/3

Hence the change of rate of x is -1/3 .

The response to this question is that p has a value of 8, or the cube root of 8. i.e. p=∛8.

An integer y such that y³ = x is known as the cube root of a number x in mathematics. All nonzero complex numbers have three different complex cube roots, while all nonzero real numbers have exactly one real cube root and two complex conjugate cube roots. When we multiply a factor three times to obtain a number, we have obtained the cube root of that factor. Three cube root of, ending cubic root is the sign for the cube root. In contrast to cubing an integer, finding its cube root is a mathematical operation.

According to the equation, p³=8

We can clearly see that the power of p is 3.

Now by taking cube root on both the sides, we can see that the value of p is

∛p³=∛8

⇒p=∛8

The Percent Change in the number of cupcakes is 60%

The given parameters are:

Initial number of cupcakes = 70

Final number of cupcakes = 112

The Percent Change in the number of cupcakes:

Percent = (Final number of cupcakes - Initial number of cupcakes)/Initial number of cupcakes  * 100%

This gives

Percent = (112 - 70)/70 * 100%

Evaluate the quotient

So, we have

Percent = 0.6 * 100%

Evaluate the product

So, we have

Percent = 60%

Hence, the Percent Change in the number of cupcakes is 60%

Total 790 number of handshakes occur within the group.

According to the given question.

Total number of people = 50

Number of people who know each other = 30

Number of people who know no one = 20

Since, 20 people doesn't knw each any one, so they will shake hands.

So, the total number of hand shakes by these 20 people

= 20(20 -1)/2

= 10(19)

= 190

Also, we have to consider  that other 30 people will also shake hands with these 20 people.

So, the total number of hanshakes by these 30 and 20 people = 30 × 20 = 600

Therefore, the total number of handshakes occur within the group

= 600 + 190

= 790

Hence, total 790 number of handshakes occur within the group.

Step-by-step explanation:

the slope-intercept form :

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

but we have the slope and a point.

so, we can start with the point-slope form and then transform it :

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is the given point.

so, we have

y - 3 = 4(x - -4) = 4(x + 4) = 4x + 16

y = 4x + 19

and that's it.

The identify each representation's associated average rate of change. The average rate of change for the functions r, q, p is 5, 5, 7/3 over the range [0.3].

Given that,

We have to find over the range [0, 3], calculate each function's average rate of change. The identify each representation's associated average rate of change.

The equation for f(x) average's rate of change across [a,b] is

m=[tex]\frac{f(b)-f(a)}{b-a}[/tex]

The function provided is

r(x)=x²+2x-5

r(0)=(0)²+2(0)-5=-5

r(3)=(3)²+2(3)-5=9+6-5=15-5=10

Now,

m₁=[tex]\frac{r(3)-r(0)}{3-0}[/tex]

m₁=[tex]\frac{10+5}{3}[/tex]

m₁=15/3

m₁=5

It is clear from the graph that q(0)=2 and q(1)=3.

Now,

m₂=[tex]\frac{q(1)-q(0)}{1-0}[/tex]

m₂=[tex]\frac{3+2}{1}[/tex]

m₂=5/1

m₂=5

It is evident from the above table that s(0)=-2 and s(3)=5.

Now,

m₃=[tex]\frac{s(3)-s(0)}{3-0}[/tex]

m₃=[tex]\frac{5+2}{3}[/tex]

m₃=7/3

If Y depends on X then the regression line is Y on X.

Y is dependent variable and X is independent variable. If X depends on Y, then regression line is X on Y and X is dependent variable and Y is independent variable. The regression equation Y on X is Y = a + bx, is used to estimate value of Y when X is known.

Answer:

4,545.45 crates

Step-by-step explanation:

.11x = 500

Divide both sides by .11

x = 4,545.45

The number of crates she picked algebraically is 4545.

Let us consider the variable "c" to represent the number of crates Brianna picked.

We know that she receives 11 cents per crate.

1 crate = $0.11 (11 cents)

Her total earnings from picking "c" crates can be expressed as:

Earnings = 0.11c

Now, we know her total piecework earnings for last week were $500. So, we can set up an equation:

Total Earnings = $500

0.11c = $500

To find the number of crates Brianna picked, we need to solve for "c":

c = $500 / 0.11

c = 4545.45...

c = 4545 crates

So, algebraically, Brianna picked approximately 4545 crates last week.
