4m² – 3m6 – 5m4<br> What is the degree of the polynomial?
Papessa [141]

Answer:

Degree of the polymonial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.

Step-by-step explanation:

I think the equation is 4m² – 3m^{6}- 5m^{4}

Therefore, degree of the polynomial is the sum of the powers of the variables,

2 + 6 + 4 = 12

Hope this helps!

Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 mile
nordsb [41]

Answer:

1153.5 miles (first answer choice)

Step-by-step explanation:

'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise').  Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:

d = √(1000² + 575²) = 1153.5 miles (first answer choice)

Distance Formula D=√(x2-x1)² + (y2 - y₁) ² a. 8.149 b. 8.84 c. 9.438 d.12.369 ​
lakkis [162]

Answer:

d

Step-by-step explanation:

using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )

d = \sqrt{10-(-2))^2+(1-4)^2}

   = \sqrt{(10+2)^2+(-3)^2}

  = \sqrt{12^2+9}

  = \sqrt{144+9}

  = \sqrt{153}

  ≈ 12.369
