Answer:

C. $(5x^3-7)(2x^2+1)$

Step-by-step explanation:

Given expression is,

$10x^5+5x^3-14x^2-7$

$=10x^5-14x^2 + 5x^3 - 7$ (By the commutative property)

$=2x^2(5x^3-7)+5x^3-7$ (Taking $2x^3$ common from first two terms )

$=(5x^3-7)(2x^2+1)$ (Taking $5x^3-7$ common from both terms)

$\implies 10x^5+5x^3-14x^2-7=(5x^3-7)(2x^2+1)$

Hence, Option C is correct

The temperature in degrees Celsius can be expressed by the function C(f)=59(f−32) where f is the temperature in degrees Fahrenhe

Vlad [161]

C(f) = 5/9(f - 32).....f = 39

C(39) = 5/9(39 - 32)
C(39) = 5/9(7)
C(39) = 35/9
C(39) = 3 8/9......rounds to 4

Flying against the jetstream, a jet travels 4960 miles in 8 hours. Flying with the jetstream, the same jet travels 2940 miles in

oksian1 [2.3K]

Answer:

Velocity of jet in still air is 800mph hour and velocity of wind is 180mph

Step-by-step explanation:

Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.

#Jet's velocity against jet-stream is:

$v_i=\frac{4960}{8}\\\\=620\ mph$

#Jet's velocity with jet-stream:

$v_{ii}=\frac{2940}{3}\\\\=980\ mph$

#The velocity against jet-stream is x-y and with jet-stream is x+y:

$x-y=620\\\\x+y=980\\\\\#add \ the \ two \ equations\ to \ eliminate \ y\\\\2x=1600\\\\x=800\\\\y=980-800=180$

Hence,velocity of jet in still air is 800 mph hour and velocity of wind is 180 mph.
