Find the total surface area of the triangular pyramid. Each of the faces (sides) has an area of 50.5 square inches.

1 answer:

5 0

By definition we have:
A triangular pyramid (also called tetrahedron) is a polyhedron whose surface is formed by a base that is a triangle and triangular lateral faces that converge in a vertex that is called apex (or apex of the pyramid).
It will be composed, therefore, by 4 faces, the triangular base and three lateral triangles that converge at the vertex.

Thus, the surface area is:
As = 4 * (50.5) = 202 in ^ 2
Answer:
The total surface area of the triangular pyramid is:
202 in ^ 2

What is the slope of a line that is perpendicular to the lien whose equation is 2y=3x-1

bixtya [17]

Answer:

-2/3

Step-by-step explanation:

We are to find the slope of a line which is perpendicular of a line with an equation $2y=3x-1$ .

We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.

So writing the given equation of a line in the slope intercept form:

$2y=3x-1$ ---> $y=\frac{3}{2} x-\frac{1}{2}$

Here the slope of this line is $\frac{3}{2}$ so the slope of a line which is perpendicular to the given line will be $-\frac{2}{3}$ .

60f=86 and I need to divide 60 from both sides but I don’t know how

White raven [17]

Answer:

f = 43/40 or 1 13/30

Step-by-step explanation:

60f=86

Divide each side by 60

60f/60=86/60

f = 86/60

Divide the top and bottom by 2

f = 43/30 or as a mixed number 1 13/30

Answer:

${x}^{2} - 4x = 7 {x}^{2} + 8x \\ {x}^{2} - 7 {x}^{2} = 8x + 4x \\ - 6 {x}^{2} = 12x \\ - 6x = 12 \\ x = \frac{12}{ - 6} = - 2 \\ x = - 2 \\ thank \: you$

Change the quadratic to vertex form. p(x)=2x² – 16x +7

irina1246 [14]

Answer:

Vertex form:

p(x)= 2(x - 4)^2 - 25

Step-by-step explanation:

p(x)=2x² – 16x +7

a = 2, b = -16 and c = 7

x = -b/2a

= -(-16)/2(2)

= 16/4

= 4

Plug x = 4 into the equation to find y

y = 2(4)² – 16(4) +7

y = 32 - 64 + 7

y = -25

Vertex (4, -25)

So Vertex form: y =a(x - h)^2 + k where h = 4 and k = -25

p(x) = 2(x - 4)^2 - 25
