Answer:

z = 30.45 feet

Step-by-step explanation:

The volume (V) of a triangular prism is calculated as

V = area of triangular end (A) × length

Here V = 913.5 and length = 15, thus

A × 15 = 913.5 ( divide both sides by 15 )

A = 60.9 ft²

The area of the triangle = $\frac{1}{2}$ bh ( b is the base and h the height ), thus

$\frac{1}{2}$ × 4 × z = 60.9

2z = 60.9 ( divide both sides by 2 )

z = 30.45

Identify the holes, vertical asymptotes, and horizontal asymptotes of the following.

Andrews [41]

Answer:

Horizontal asymptote: y = 0

Vertical asymptote: x = 3

Step-by-step explanation:

The vertical asymptote in this graph would be when x = 3 because it would make the denominator 0, which would make the equation undefined.

There will not be any holes in the graph, because there won't be any point undefined in the function except for when x = 3, but that's a vertical asymptote.

Now, for the horizontal asymptote, we see what value y approaches as x approaches plus and minus infinity. Since x is in the denominator, y will approach 0 when it's plus or minus infinity.

Horizontal asymptote: y = 0

Vertical asymptote: x = 3

What is the slope of a line that passes through the origin and the point (-2,1)?

Mazyrski [523]

Answer:

The slope would be -1/2.

Step-by-step explanation:

Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),

= ( 4, -2 ),

Now, the slope of the line passes through the origin and the point ( 4, -2) is,
