Answer:

x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}

Step-by-step explanation:

            x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}

x + 3 / x^{4} - 2x^{3}-21x^{2} -10x +22

         -(x^{4} + 3x^{3})

                 -5x^{3} -21x^{2} -10x +22

                 -(-5x^{3} -15x^{2})

                              -6x^{2} -10x +22

                            -(-6x^{2} -18x)

                                            8x +22

                                          -(8x + 24)

                                              \frac{-2}{x + 3}

A population analysist is using the formula Pn = 25.8(1.0219)h to predict the population for Ghana, a country in Africa. What do
Neko [114]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the formula :

Pn = 25.8(1.0219)^h to predict the population of Ghana ;

The equation given is in the form of an exponential function:

The general form of an exponential distribution :

y = ab^x

a = Initial value ; b = constant multiplier or growth or Decay factor

Comparing :

The number in parenthesis = 1.0219 = b

b = Decay or growth factor :

Since b > 1 ; then We have a growth factor;

b = 1 + rate

1.0219 = 1 + rate

Rate = 1.0219 - 1

Rate = 0.0219

Hence, the population is growing at a rate of about (0.0219)*100% = 2.19%

4x+1 ,3x find the value of x
In-s [12.5K]
I'm assuming that you meant 4x+1=3x?

Subtracting 4x, we get 1=-x.  Multiplying by -1, we get x=-1 as the solution.

Need an explanation and answer for -25/28 ÷ (5/4)
lyudmila [28]

Answer:

-5/7

When you divide fractions, you flip the second fraction, then multiply.

So it becomes -25/28 x 4/5.

This equals -100/140 which reduces to -5/7.
