If ^ ABC ≈ ^ DEC, what is the value of x?

Answers

Answer 1

Answer:

D. x=1

Step-by-step explanation:

4x-1=x+2

you cancel out the 1 by adding it to both sides so then it will be 4x=x+3

then subtract x by both sides then it will be 3x=3

then simplify then it will be x=1

a plane intersects the coordinate axes at the point (2,0,0), (0,3,0) and (0.0.4) the obteined point is ax+by+cz+d, find value of d

Answers

Answer:

d = 12

Step-by-step explanation:

In intercept form, the equation of the plane is ...

x/a +y/b +z/c = 1 . . . . . for x, y, z intercepts a, b, c

You have (a, b, c) = (2, 3, 4), so the equation of the plane is ...

x/2 +y/3 +z/4 = 1

Multiplying by 12 gets rid of the fractions and puts the equation in standard form:

6a +4y +3z = 12

The value of d is 12.

Suppose that you have $1500 to spend on fencing for your rectangular yard. The fence meets with your
house on one side, so you only need to fence three sides of the rectangle. The sides touching the house
will be equal in length, call these lengths x feet. And label the length of the third side y feet. Fencing
costs $57 per foot.
a. Write a function that expresses total fence cost as a function of x and y.
b. Write a function that expresses the total area as a function of x and y.
c. Write a function that expresses the total area as a function of x only. Assume that you want to
spend as much of that $1500 as you can.
d. Graph the result of c and past below. Be sure to include where the function reaches a maximum.

Answers

The cost function of the rectangular yard is 114x + 57y = 1500

Let x represent the length of the rectangular yard and y represent the width of the rectangular yard.

Since you need to fence only 3 sides, hence:

2x + y = Perimeter

Each foot cost $57 per foot and there is $1500 to spend, hence:

2x(57) + y(57) = 1500

114x + 57y = 1500

y = (1500 - 114x) / 57

The area (A) of the rectangular yard is:

A = x * y

A = xy

A = x[(1500 - 114x) / 57)
