Amalia is scuba diving at a position 24.25 feet below sea level.she descends 0.5 foot each minute for 25 minutes what is Amalias
vlada-n [284]
We can represent her initial position as -24.25, since it says she is 24.25 feet below sea level.
If she descends -.5 feet per minute, all we have to do is multiply -.5 by 25, and add it to her initial position to get the answer.
-.5*25=-12.5
-24.25+-12.5=-36.5
Her current position is -36.5
Hope this helps!

PLEASE HELP! DUE TONIGHT! The table of ordered pairs shows a the coordinates of the two points on the graph of a line.
erastova [34]
You would graph the two lines. Then use  Y=mX+b
10=5/4(4)+b  5/4 is the slope or distance between the two lines.
solve for b 
10=5+b
-5
5=b 
Y=5/4X+5 would be your answer

A triangle has vertices at A(-2,3), B(2,-2), and C(-2,-2). What is the area of the triangle?
Softa [21]

Answer:

The area of the given triangle ABC is 10 units.

Step-by-step explanation:

we have the area of the triangle when points are given is given by the relation

Area of triangle=

\frac{1}{2} {x1 \times (y2 - y3) + x2 \times (y3 - y1) + x3 \times (y1 - y2)}

and hence putting the Value

triangle = 1/2*( -2*(-2+2)+2*(-2-3)+(-2)*(3+2))

= 1/2*(0+2*(-5)+(-2)*5)

= 1/2*(-10-10)

= 1/2*(-20)

= (-10) units

Since area of the triangle is always positive, we neglect the minus sign and take 10 units as its area.

(x+1)^2 . (x^2+1) = 0
Maurinko [17]

Answer:

x^4+2x^3+2x^2+2x+1

Step-by-step explanation:

Given that,

(x+1)^2 . (x^2+1) = 0

We know that, (a+b)^2=a^2+b^2+2ab

So,

(x+1)^2=x^2+1+2x

So,

(x+1)^2 . (x^2+1) = (x^2+1+2x)(x^2+1)\\\\=x^2\times x^2+x^2+2x^3+x^2+1+2x\\\\=x^4+2x^3+2x^2+2x+1

So, the value of the given expression is equal tox^4+2x^3+2x^2+2x+1
