Finding surface area
To find the surface area of a prism, use the formula SA=2B+ph, where SA stands for surface area, B stands for area of the base of the prism, p stands for the perimeter of the base, and h stands for the height of the prism. Since this is a triangular prism, substitute the area formula of a triangle for B.
Answer:
y = (1/3)x + 7
y = (1/3)x - 15
These are two examples out of an unlimited number of possibilities.
Step-by-step explanation:
The slope of this given line is -3. Any new line perpendicular to this one is the negative reciprocal of -3: 1/3.
The slope-intercept form is y = mx + b. Here m = 1/3, so the revised form is
y = (1/3)x + b.
Two straight lines perpendicular to the given line are easily found by selecting two different values for b:
y = (1/3)x + 7
y = (1/3)x - 15
Answer:
k(-7) = -27
Step-by-step explanation:
K(n) = 4x + 1
find k(-7)
so we have 4(-7 ) +1
-28 +1
Therefore, k(-7) = -27
Answer:
x=7/10
Step-by-step explanation:
2/5=4/10
11/10=x+4/10
11/10-4/10=x
7/10=x
