We know that
[surface area]=2*[area of the base]+[perimeter of the base]*height of prism
area of the base= area of <span>a equilateral triangle
b=3 cm
h=2.6 cm
area of the base=b*h/2-----> 3*2.6/2----> 3.9 cm</span>²
perimeter of the base=perimeter of a equilateral triangle
b=3 cm
perimeter=3*(3)-----> 9 cm
[surface area]=2*[area of the base]+[perimeter of the base]*height of prism
[surface area]=2*[3.9]+[9]*6-----> 7.8+54-----> 61.8 cm²
the answer is
61.8 cm²
Answer:
Step-by-step explanation:
given: (2,1) & (5-8)
first find the slope,
m= (Y2-Y1) / (X2-X1)
m=(-8-1)/(5-2)
m=(-9)/(3)
m=-3
we have y=-3x+b
use any point to sub in x and y
1=-3(2)+b
1+6=b
b=7 therefore, y=-3x+7 is the equation
The formula is y-y1=slope(x-x1)
so the answer is y-2 = 3/5(x-10)
Answer:
1. Not a function: The x value is repeated.
2. brainly.com/question/5008648
3. Yes, passes vertical line test.
4. Yes, y values can be repeated.
