What is the degree of -8mn^2

20 points!!!

Inga [223]

Answer:

82

Step-by-step explanation:

We are given that a graph which shows the number of beads used for varying cord lengths.

The graph

$y=2.52x+1.61$

We have to find the number of beads that she can used for cord length 32 in.

Substitute the value x=32

Then, we get

$y=2.52(32)+1.61=82.25$

After round to unit place then, we get

y=82

Hence, the best estimate she can used for number of beads =82

Determine the fraction of total interest owed using the rule of 78. After the six month of a 12 month loan, the numerator is: {(

Dima020 [189]

Answer:

The fraction of total interest owed is $\frac{57}{78}$

The value of it to the nearest tenth is 73.1%

Step-by-step explanation:

Let us solve it using the rule of 78

∵ The loan = 12 month

∵ The numerator is after 6 month

- Substitute n by 1 in each bracket

∴ The numerator = {(1 + 11) + (1 + 10) + (1 + 9) + (1 + 8) + (1 + 7) + (1 + 6)}

∴ The numerator = {12 + 11 + 10 + 9 + 8 + 7}

∴ The numerator = {57}

∴ The numerator of the fraction is 57

∵ The denominator = {(n) + (n + 1) + (n + 2) + .......... + (n + 11)}

- substitute n by 1 in each bracket

∴ The denominator = {1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}

∴ The denominator = {78}

∴ The denominator of the fraction is 78

The fraction of total interest owed is $\frac{57}{78}$

Now find the value of the fraction

∵ The fraction = $\frac{57}{78}$

∴ Its value = 0.7307692308 × 100%

∴ Its value = 73.07692308%

- Round it to the nearest tenth

∴ Its value = 73.1%

The value of it to the nearest tenth is 73.1%

I forgot to do slopes

Minchanka [31]

To find the slope of the line, use the rise over run formula:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Take any two points from the line and plug them into the formula.

(0,0) and (10, 5)

$\frac{5 - 0}{10 - 0} = \frac{5}{10} = 0.5$

The slope of the line is 0.5.

Using the form y = mx, the following equation will be your answer:

$y = 0.5x$
