Find the degree of the polynomial 9x^3 y6 + 2.5xy + x^2 .

1 answer:

6 0

The degree of the polynomial is 9 ( not determined by the first number)
The degree of a polynomial is the highest exponent.
Here the highest exponent is 6 but since y is not a term on its own, you add the exponent of the term together.

What is the solution to the system of equations? Use the substitution method. {y=2x+43x−6y=3

garri49 [273]

We have that
y=2x+4--------> equation 1
3x−6y=3-------> equation 2

step 1
I substitute the value of y in equation 1 for the value of y in equation 2
so
3x−6*[2x+4]=3-------> 3x-12x-24=3
-9x=3+24
-9x=27------> 9x=-27
x=-27/9
x=-3

step 2
I substitute the value of x in equation 1 to get the value of y
y=2x+4--------> y=2*(-3)+4--------> y=-6+4
y=-2

the answer is
the solution is the point (-3,-2)
x=-3
y=-2

Evaluate the following if k=0.5, n=-3, and p=-2: K+n(p^2)

ivann1987 [24]

Answer:

-11.5

Step-by-step explanation:

$K + n( {p}^{2} ) \\ \\ plug \: K = 0.5, \: n = - 3, \: p = - 2 \\ \\ K + n( {p}^{2} ) \\ \\ = 0.5 + ( - 3) \{ {( - 2)}^{2} \} \\ \\ = 0.5 - 3 \{ 4 \} \\ \\ = 0.5 - 12 \\ \\ = - 11.5$

Someone please please help me with this !

Elanso [62]

Answer:

551.8 feet

Step-by-step explanation:

We are given

Adjacent = 1300 feet

Opposite = x

Angle = 23°

We solve using the trigonometric function Tangent

tan θ = Opposite/Adjacent

tan 23 = x/1300 feet

Cross Multiply

x = tan 23 × 1300 feet

x = 551.81726107 feet

Approximately = 551.8 feet

The Length of the building = 551.8 feet
