Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 3)

Point (1, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{5-3}{1-0}$
[Slope] Subtract: $\displaystyle m=\frac{2}{1}$
[Slope] Divide: $\displaystyle m=2$

Which of the following is a polynomial A.x^2+2 B.(x^8-2)/(x^-2+3) C. 7x^7-2x^-4+3 D.x^x-1

EastWind [94]

A. x²+2 - a polynomial
B.(x⁸-2)/(x⁻²+3) rational function
C. 7x⁷-2x⁻⁴+3 (It has negative value of exponent, so it cannot be a polynomial.)
D.x^x-1 (x is an exponent it cannot be a polynomial)

Find the perimeter and round your answer to the nearest tenths. Can anyone help me with this? I cannot find any videos or exampl

Answer:

22.8

Step-by-step explanation:

the rectangular has :

the length CD =√[(3+3)²+(0-5)²]

= √(36+25) = √61 = 7.8

the width BC =√[(5-3)²+(3-0)²]

=√(4+9 =√13 = 3.6

so, the perimeter = 2(7.8 + 3.6)

= 2× 11.4 = 22.8
