What is the scale factor, perimeter ratio, surface ratio, and the volume ratio?????????????????????????????

tamaranim1 [39]

Answer:

Scale factor = $\frac{4}{9}$

Perimeter ratio = 4 : 9

Surface area ratio = 16 : 81

Volume ratio = 64 : 729

Step-by-step explanation:

Volume ratio = $\frac{\text{volume of small prism}}{\text{Volume of large prism}}$

= $\frac{128}{1458}$

= $\frac{64}{729}$

= 64 : 729

Scale factor = $\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}$

= $\sqrt[3]{\frac{64}{729}}$

= $\frac{4}{9}$

Perimeter ratio = Scale factor

= $\frac{4}{9}$

= 4 : 9

Surface area ratio = (Scale factor)²

= $(\frac{4}{9})^{2}$

= $\frac{16}{81}$

= 16 : 81

M = 3, through (1,-1) Point-Slope Slope intercept

Lapatulllka [165]

Answer:

$\large\boxed{y+1=3(x-1)}\\\\\boxed{y=3x-4}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - a point on a line

We have

$m=3,\ (1,\ -1)\to x_1=1,\ y_1=-1$

Substitute:

$y-(-1)=3(x-1)\\\\\boxed{y+1=3(x-1)}$

Convert to the slope-intercept form

$y=mx+b$

m - slope

b - y-intercept

$y+1=3(x-1)$ use the distributive property

$y+1=3x-3$ subtract 1 from both sides

$\boxed{y=3x-4}$
