Mathematics
1 answer:
DIA [1.3K]2 years ago
5 0

Answer:

Step-by-step explanation:

The discriminate part of the quadratic solution is sqrt(b^2 - 4ac). If this is  less than 0, then you get an imaginary result.

a = 2      b= 4     c = 2

sqrt(4^2 - 4 * 2 * 2)

sqrt(16 - 16) = 0

a does not give any imaginary roots.

Try D

a = 3        b= 2       c = 1

sqrt(2^2 - 4*3 * 1)

sqrt(4- 12)

sqrt(-8)

This gives you an imaginary zero because - 8 has an imaginary sqrt.

Answer:

about 15.328 yrds

two sides are 5 yrds, so 5+5= 10yrds. two sides are 8 ft, 8+8=16 ft. there are .3333 yrds in 1 foot so 16*.3333 = about 5.328yrds

10+5.328 = 15.328

An automobile engineer is redesigning a conical chamber that was originally specified to be 12 inches long with a circular base
kirill115 [55]

Answer:

the original volume is lesser than the new volume by 242.47 in³

Step-by-step explanation:

Volume of a cone is;

V = ⅓πr²h

Where;

r is radius

h is height

For the original chamber;

r = 5.7/2 = 2.85 inches

h = 12 inches

Volume of this original chamber is;

V_orig = ⅓ × π × 2.85² × 12

V_orig = 102.02 in³

In the new design, the chamber is scaled by a factor of 1.5.

Thus;

r_new = 2.85 × 1.5 = 4.275 inches

h_new = 12 × 1.5 = 18 inches

V_new = ⅓ × π × 4.275² × 18

V_new = 344.49 inch³

V_new - V_orig = 344.49 - 102.02 =

Thus, the original volume is lesser than the new volume by 242.47 in³
