Answer:

-105.3,729,-2843.1

Step-by-step explanation:

so I ruled out addition and subtraction cause it's not decreasing or increasing regularly

so I considered division and multiplication

where I did the latter over the former

3.9/1= -39/10 and 27/-3.9=-90/13

so I used the two to form an alternating pattern

27×{-39/10}= -105.3

-105.3×{-90/13}= 729

729×{-39/10}= -2843.1

Morgarella [4.7K]

Answer:

= 4 1/6 ---------------> final answer

Step-by-step explanation:

1 2/3 cup of sugar

That is : 5/3 cups of sugar for 1 cookie recipe

So for 1 recipe ------------- 5/3 cups of sugar

hence for 2 1/2 recipe ---------------> (5/3) * (5/2)

= 25/6

= 4 1/6 ---------------> final answer

Given the function f(x) = x3 + x2 − 2x + 1, what is the resulting function when f(x) is shifted to the left 1 unit?

Mekhanik [1.2K]

The answer is B.

Explanation:

If c is a positive real number, then the graph of
f(x – c) is the graph of y = f(x) shifted to the right
c units.
Horizontal Shifts
If c is a positive real
number, then the
graph of f(x + c) is
the graph of y = f(x)
shifted to the left

Find the value of kk for which the constant function x(t)=kx(t)=k is a solution of the differential equation 5t3dxdt+2x−2=05t3dx

uranmaximum [27]

Given the differential equation

$5t^3 \frac{dx}{dt} +2x-2=0$

The solution is as follows:

$5t^3 \frac{dx}{dt} +2x-2=0 \\ \\ \Rightarrow5t^3 \frac{dx}{dt} =2-2x \\ \\ \Rightarrow \frac{5}{2-2x} dx= \frac{1}{t^3} dt \\ \\ \Rightarrow \int {\frac{5}{2-2x} } \, dx = \int {\frac{1}{t^3}} \, dt \\ \\ \Rightarrow- \frac{5}{2} \ln(2-2x)=- \frac{1}{2t^2} +A \\ \\ \Rightarrow\ln(2-2x)= \frac{1}{5t^2} +B\\ \\ \Rightarrow2-2x=Ce^{\frac{1}{5t^2}} \\ \\ \Rightarrow 2x=Ce^{\frac{1}{5t^2}}+2 \\ \\ \Rightarrow x=De^{\frac{1}{5t^2}}+1$
