Answer:

The length of the river on a map is 9.6\ cm

Step-by-step explanation:

we know that

The scale of the map is 1:5,000,000

That means

1 cm on a map is 5,000,000 cm on the actual

or

1 cm on a map is 50 km cm on the actual

so

using proportion

\frac{1}{50}\frac{cm}{km}=\frac{x}{480}\frac{cm}{km}\\ \\x=480/50\\ \\x=9.6\ cm

Which correctly describes the roots of the following cubic equation x^3-5x^2+3x+9=0? A. Three real roots, each with a different
77julia77 [94]

Answer:

The correct option is C.

Step-by-step explanation:

The given cubic equation is

x^3-5x^2+3x+9=0

According to the rational root theorem 1 and -1 are possible rational roots of all polynomial.

At x=-1, the value of function 0. Therefore (x+1) is the factor of polynomial and -1 is a real root.

Use synthetic division to find the remaining polynomial.

(x+1)(x^2-6x+9)=0

(x+1)(x^2-2(3)x+3^2)=0

Using (a-b)^2=a^2-2ab+b^2

(x+1)(x-3)^2)=0

USe zero product property and equate each factor equal to 0.

x=-1,x=3,x=3

Therefore the equation have three real roots out of which the value of two roots are same.

Option C is correct.

How many minutes he does arm routine and abdominal routine
AlekseyPX
Let x be the amount of time it takes to perform an arm routine and y be the amount of time it takes to perform an abdominal routine.  We see:

4x+y=70
4x+2y=100

Subtracting the second equation from the first gives y=30.  Substituting gives 4x+30=70, so 4x=40 and x=10.

Thus, an arm routine takes ten minutes and an abdominal routine takes thirty minutes.
