Answer:

I hope it helps it was the best I can do.

Step-by-step explanation:

-x12 + x7 = 0

Factorization:

−x7(x − 1)(x4 + x3 + x2 + x + 1) = 0

Solutions based on Jenkins–Traub algorithm:

x1 = … = x7 = 0

x8 = 1

x9 = −0.809017 − 0.587785i

x10 = −0.809017 + 0.587785i

x11 = 0.309017 − 0.951057i

x12 = 0.309017 + 0.951057i

What is the area of triangle HGF? Round your answer to the nearest tenth of a square centimeter. Recall that you need to round u

denpristay [2]

Answer:

9.8

Step-by-step explanation:

The formula for the area of a triangle is a=bh/2, where a is area, b, is the base, and h is the height. If we substitute the values in the question in the equation, we get:

a=(6.5*3)/2

a=19.5/2

a=9.75

a≈9.8

Two trains left the station traveling in opposite directions. The distance Train A traveled is modeled by the function d(t)=81t

stira [4]

Answer:

Option A - The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Step-by-step explanation:

Given : The distance Train A traveled is modeled by the function $d(t)=81t$

where d represents distance in miles and t represents time in hours.

To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?

Solution :

Distance traveled by Train A in 1 hour is

$d(t)=81t$

$d(t)=81(1)=81$

Distance traveled by Train B in 1 hour is

$d(t)=81t$

$d(t)=81(1)=81$

or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour

Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Hence, Option A is correct.
