Answer:

The correct answer is A) x^6y^8

Step-by-step explanation:

The easiest way to find this is to first square the second term.

(-x^2y^3)^2 = (x^4y^6)

Now we multiply that by the first parenthesis.

(x^2y^2)(x^4y^6) = x^6y^8

my son had his 18 months visit to the doctor last week.the nurse took several measurement while we were there.his length(height)
nikitadnepr [17]

18 months ……33inches, weight 25.5 pounds

When he was born = 9 months…20 inches, weight 8, 4 pounds

Every 9 months his height growth is 33-20 = 13 inches, his weight is 25.5-8.4=17.1 pounds 

<span>Pounds.  This means, for every 9 months, his growth is 13 inches and his weight is 17.1 pounds. For example we can determine his growth in 3 years.</span>

<span>3 years = 36 months, 36= 9*4, his height will be 4*13 inches= 52 inches, his weight will be 4*17.1 = 68.4 pounds </span>

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21
Mice21 [21]

Answer:

(-4,-13) and (4,3) the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

f(x)=2x-5

g(x)=x^2+2x-21

For a common point of these functions,

f(x)=g(x)

2x-5=x^2+2x-21

-5=x^2-21

0=x^2-16

x^2=16

x=-4,4

For x=-4,

f(-4)=g(-4)=2(-4)-5

                       =-13

For x=4,

f(4)=g(4)=2(4)-5

                  =3

Therefore, (-4,-13) and (4,3) the intersection points.

Explain in words how you would evaluate the expression 5.1 + q ÷ 3.4 for q = 28.9
statuscvo [17]
You would plug in twenty eight point nine to the q. So it would be five point one plus twenty eight point nine divided by three point four, which equals thirteen point six.
