Write an equation of a parabola that opens to the left, has a vertex at the origin, and a focus at (–4, 0).
8_murik_8 [283]

Answer:

y^{2}=-16x

Step-by-step explanation:

we know that

The standard equation of a horizontal parabola is equal to  

(y-k)^{2}=4p(x-h)

where

(h,k) is the vertex

(h+p,k) is the focus

In this problem we have

(h,k)=(0,0) ----> vertex at origin

(h+p,k)=(-4,0)

so

h+p=-4

p=-4

substitute the values

(y-0)^{2}=4(-4)(x-0)

y^{2}=-16x

Find the percent cost of the total spent on each equipment $36, fees $158, transportation $59
maksim [4K]

Answer: Therefore, Option 'A' is correct.

Step-By-Step  explanation:

Since we have given that

Amount spent on equipment = $36

Amount spent on fees = $158

Amount spent on transportation = $59

Total amount spent by them is given by

36+158+59=\$253

Percent cost of equipment of the total amount is given by

\frac{36}{253}\times 100=14.2\%

Percent cost of fees of the total amount is given by

\frac{158}{253}\times 100\\\\=62.45\%

Percent cost of transportation of the total amount is given by

\frac{59}{100}\times 100\\\\=23.3\%

Hence, Percent cost of the total spent on each is

14%, 62%, 23%.

Therefore, Option 'A' is correct.
