Answer:
length: 50 ydwidth: 40 ydStep-by-step explanation:
The perimeter is twice the sum of length and width. Then the sum of length and width is 90 yards. Their product is the area, so we have ...
x(90 -x) = 2000 . . . . where x is length or width
x^2 -90x +2000 = 0 . . . . rearrange to standard form
(x -40)(x -50) = 0 . . . . . . . factor
x = 40 or x = 50
The dimensions of the rectangular plot are 40 yards by 50 yards.
ABCD is a quadrilateral with AB equal and parallel to DC. prove that AD is equal and parallel to BC
Answer: see below proof
Step-by-step explanation:
Imagine a diagonal line AC
If AB = DC and AB // DC then angle BAC =
Angle ACD Alternate Interior angles theorem.
Then if AB = AD and angle BAC = angle ACD and AC = AC then triangle ABC is congruent to triangle CDA.
If triangle ABC is congruent to triangle CDA then AD = BC because congruent parts of congruent triangles are congruent.
If triangle ABC is congruent to triangle CDA then angle ACB = angle CAD because congruent parts of congruent triangles are congruent.
If angle ACB = angle CAD then AD // BC because of the alternate interior angles theorem.

Solve for x
4^x/9^x=½
Answer:
x = 0.85476
Step-by-step explanation:
4ˣ/9ˣ=½
9ˣ / 4ˣ = 2
(9/4)ˣ = 2
2.25ˣ = 2 .... aⁿ = x logₐx = n
log₂.₂₅2 = x
x = 0.85476

Answer:
n ≥ -95
Step-by-step explanation:
[tex]\frac{n}{-5}[/tex] -4 ≤ 15
[tex]\frac{n}{-5}[/tex] ≤ 19 add 4 to 15
n ≥ -95 multiple -5 to 19; sign flips when multiplying or dividing an inequality

we just need to minus 10 with 5.5 so that we can find d
A puzzle box has a height of 27 centimeters. It has a base with an area of 220 square centimeters. What is the volume, in cubic centimeters, of the puzzle box?
Answer:
5940 cm^3
Step-by-step explanation:
Step one:
given data
Height = 27 cm^3
Area= 220 cm^2
Required
the volume of the box
Step two:
the expression for volume is
V= Area* height
v= 220*27
V= 5940 cm^3

What is the slope of a line that is perpendicular to the line in the graph?
Answer:
The slope of the required line is 1
Step-by-step explanation:
The Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The graph shows a line whose slope can be calculated by selecting two points it goes through. Let's pick points (0,0) and (2,-2). Thus the slope is:
[tex]\displaystyle m=\frac{-2-0}{2-0}=-1[/tex]
The slope (m') of a line that is perpendicular to the line in the graph can be found by using the equation:
m*m'=-1
Solving for m':
[tex]m'=-\frac{1}{m}=-\frac{1}{-1}=1[/tex]
Thus the slope of the required line is 1

Step-by-step explanation:
Solve for w. -34=-6+w/4
Answer:
w=−112
Step-by-step explanation:
-34=-6+w/4
Simplify both sides of the equation.
−34=−6+ w /4
−34=−6+ 1 /4 w
−34= 1 /4 w−6
Flip the equation.
1 4/ w−6=−34
Add 6 to both sides.
1 /4 w−6+6=−34+6
1 /4 w=−28
Multiply both sides by 4.
w=−112
Answer:
w = - 112
Step-by-step explanation:
-34=-6+w/4
1. Add 6 on both sides
-34 + 6 = -6 + 6 + w/4
-28 = w/4
2. Multiply 4 on both sides since it's the opposite of dividing
-28 * 4= w/4 * 4
- 112 = w
Hope this helped!

Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.
Answer:
Solution,
f(x) = [tex]x^{3}[/tex] + 1
Put x = x - 3,
f(x - 3) = [tex](x-3)^{3}[/tex] + 1
Now,
g(x) = f(x - 3) + 1
or, g(x) =[ [tex](x-3)^{3}[/tex] +1 ] + 1
or, g(x) = [tex]x^{3} -9x^{2} + 27x - 1 + 1+1[/tex]
or, g(x) = [tex]x^{3} - 9x^{2} +27x + 1[/tex]
