Answer:
Step-by-step explanation:
first we gotta find the slope of the first line
(-4,-3),(4,1)
slope = (y2 - y1) / (x2 - x1) = (1- (-3) / (4 - (-4) = (1 + 3) / (4 + 4) = 4/8 = 1/2
so the slope is 1/2.....so we are looking for a line that is perpendicular....perpendicular lines have negative reciprocal slopes...all that means is flip the slope and change the sign....so the slope we need is :
1/2....flip it....2/1.....change the sign....-2.....we need a -2 slope
y - y1 = m(x - x1)
slope = -2
(-4,3)...x1 = -4 and y1 = 3
now sub
y - 3 = -2(x - (-4) =
y - 3 = -2(x + 4) <=====

Step-by-step explanation:
El paralelismo cuadrilátero es cuando las líneas paralelas se mantienen separadas a la misma distancia y nunca se cruzan (cruzan). Las líneas verdes marcan los lados de igual (la misma) longitud y las flechas azules marcan los lados que son líneas paralelas. Los cuadriláteros con líneas perpendiculares tienen lados que se encuentran en un ángulo recto (90 °).
Answer:
593.04 square inches leather is needed.
Step-by-step explanation:
Leather needed to sew a ball = Surface area of the ball
Surface area of the sphere = 4πr²
= 4π(6.55)²
= 539.13 inches²
Since 10% extra material is needed for the seams, amount of material required = 539.13 + (10% of 539.13)
= 593.043
= 593.04 square inches
593.04 square inches of leather will be needed.
