Mathematics
1 answer:
Citrus2011 [14]3 years ago
3 0

Answer:

x^2 -10x - 15 = 0

(don't know how far you want me to go)

Step-by-step explanation:

(x - 5)^2 = 40

(expand the brackets)

(x - 5)(x - 5) = 40

x^2 -5x -5x + 25 = 40

x^2 -10x + 25 = 40

x^2 -10x - 15 = 0

If the altitude is √7, find the volume. 36√7 cu. units 18√7 cu. units 12√7 cu. units
rosijanka [135]

Answer:

Volume = 12\sqrt{7} cubic units

Step-by-step explanation:

Volume of the square pyramid is given as ⅓*area of base*height of pyramid.

Where,

Area of base = 6*6 = 36

Height of pyramid = altitude = \sqrt{7} units

Plug the values into the formula to find volume.

Volume = \frac{1}{3}*36*\sqrt{7}

Volume = 12*\sqrt{7}

Volume = 12\sqrt{7} cubic units

HELP PLZZ ASAP !! a. The value of x is 6 , what is the value of y?
erastovalidia [21]

Answer:

a). y = 4.5

b) Scale factor = \frac{3}{4}

Step-by-step explanation:

a). Since, polygon Q is the scaled copy of polygon P

    Both the figures will be similar.

    Therefore, their corresponding sides will be proportional.

    \frac{x}{y} =\frac{4}{3}

    If x = 6,

    \frac{6}{y} =\frac{4}{3}

    y = \frac{3\times 6}{4}

    y = 4.5

b). Since, polygon Q is the scaled copy of polygon P,

    Polygon Q will be the image of preimage polygon P.

    Scale factor = \frac{\text{Length of a side of the image}}{\text{Length of a side of the preimage}}

                         = \frac{3}{4}
