Describe how you labled the bar model and wrote a number sentence to solve exercise 2

mafiozo [28]

Answer:

31

Step-by-step explanation:

In the above problem it is given that

No of Bees in the hive = 14

Number of bees in the garden = 17

In order to solve it

First of all I wrote 14 in the first box which represents the number of bees in the hive.

Secondly, I wrote 17 in the second box which represents the number of bees in the garden.

Now, in order to calculate the total number of bees i added the number in both boxes

Total Number of bees = 14 + 17

Total Number of bees = 31

So our total number of bees are 31

A) Show that the equation 20-x^3-7x^2=0 can be rearranged to give x=20/x^2 - 7

AVprozaik [17]

Answer:

Step-by-step explanation:

$20-x^3-7x^2=0$

a)

Add $x^3$ to both sides of the equation: $20-7x^2=x^3$
Divide both sides by $x^2$ : $\frac{20}{x^2} -\frac{7x^2}{x^2} =\frac{x^3}{x^2}$ ⇒ $\frac{20}{x^2} -7 =x$

b)

$x_1=\frac{20}{(x_0)^2} -7$

⇒ $x_1=\frac{20}{(-9)^2} -7$

⇒ $x_1=-\frac{547}{81}$

$x_2=\frac{20}{(x_1)^2} -7$

⇒ $x_2=\frac{20}{(-\frac{547}{81})^2} -7$

⇒ $x_2=-6.561443673...$

$x_3=\frac{20}{(x_2)^2} -7$

⇒ $x_3=\frac{20}{(-6.561443673...)^2} -7$

⇒ $x_3=-6.535451368...$

c) approximation to the location of one of the roots of the equation. Each iteration gives a slightly more accurate value of a root $x$ .

Danny solved the inequality - 8x > 56 and got x>-7. Is this correct and if not, what mistake did Danny

aniked [119]

Answer:

Danny did not reverse the symbol.

Hence, the correct answer is: $x$

Step-by-step explanation:

Given the inequality

$- 8x > 56$

We know that when we multiply both sides by -1, the 'inequality' gets reverse.

i.e.

$\left(-8x\right)\left(-1\right)$

$8x$

Divide both sides by 8

$\frac{8x}{8}$

$x$

Therefore, Danny did not reverse the symbol.

Hence, the correct answer is: $x$
