The reduction was 1/5.

Because you are given the reduced values, multiply the reduced value by the inverrse of the factor:

Inverse of 1/5 = 5

Height = 3 x5 = 15

Base = 5 x 5 = 25

The base is 25

The oblique pyramid has a square base with an edge length of 5 cm. The height of the pyramid is 7 cm. What is the volume of the
ExtremeBDS [4]
The answer is <span>58 cm3
</span>
The volume of the pyramid with square base is:
V = s² * h / 3
s - the edge length, s = 5 cm
h - height, h = 7 cm

V = 5² * 7 / 3
V = 25 * 7 / 3
V = 58 cm³

3t - 7 = 5t, then 6t= ?
netineya [11]

Answer:

  1. t = -5/2
  2. -21

Step-by-step explanation:

3t - 7 = 5t

~Subtract 3t to both sides

-7 = 2t

~Divide 2 to both sides

-7/2 = t

~Find 6t with what we found for t

6(-7/2)

-21

Best of Luck!

Write an equation for a parabola with a focus of (1,-2) and a directrix of y=6
FinnZ [79.3K]

Answer:

y = - \frac{1}{16}(x - 1)² + 2

Step-by-step explanation:

Any point (x, y) on the parabola is equidistant from the focus and the directrix.

Using the distance formula

\sqrt{(x-1)^2+(y+2)^2^} = | y - 6 |

Square both sides

(x - 1)² + (y + 2)² = (y - 6)² ( expand the factors in y )

(x - 1)² + y² + 4y + 4 = y² - 12y + 36 ( subtract y² - 12y from both sides )

(x - 1)² + 16y + 4 = 36 ( subtract 4 from both sides )

(x - 1)² + 16y = 32 ← subtract (x - 1)² from both sides )

16y = - (x - 1)² + 32 ( divide all terms by 16 )

y = - \frac{1}{16} (x - 1)² + 2
