Determine the gradient and the y-intersect point of:

maks197457 [2]

Answer:

gradient:

3x+2y=5

3(1)+2dy/dx=0

3+2dy/dx=0

2dy/dx=-3

dy/dx=-3/2.

y-intersect:

3x+2y=5

2y=5-3x

y=5-3x/2

$\qquad\qquad\huge\underline{{\sf Answer}}$

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

$\qquad \sf \dashrightarrow \: 28 : 4$

to put in simple Ratio ~

$\qquad \sf \dashrightarrow \: 7: 1$

So, the sides of the larger polygon are :

4 × 7 = 28

6 × 7 = 42

3 × 7 = 21

4 × 7 = 28

7 × 7 = 49

3 × 7 = 21

3 × 7 = 21

4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

$\qquad \sf \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28$

$\qquad \sf \dashrightarrow \:238 \: \: units$

87.6564 to DP Please help me, thanks

kirill115 [55]

<span>1. </span><span>DP , you mean decimal points?
87.6564 is already written in decimals points.
it is a combination of a whole number and a decimal points.
=> 87 is the whole number where 8 is tens and 7 is the ones.
=> 6564 is the decimal numbers where 6 next to the decimal point is tenths, 5 is hundredths, 6 is the thousandths and 4 is the ten thousandths.
When you round this number to its nearest tenths, it becomes 87.7</span>
