Answer:

  • width: 7.26 ft
  • length: 8.26 ft

Step-by-step explanation:

Let w represent the width of the rectangle. Then w+1 is the length, and the area is ...

  w(w+1) = 60

  w^2 +w + 0.25 = 60.25 . . . . eliminate parentheses, complete the square

  (w +0.5)² = 60.25

  w +0.5 = √60.25

  w = -0.5 +√60.25 ≈ 7.26 . . . . . feet

  w+1 = 8.26 . . . . feet = length

The dimensions of the rectangle are 7.26 feet by 8.26 feet.

Monica has a triangular piece of fabric. The height of the triangle is 27 inches and the triangle's base is 18 inches. Monica sa
Fed [463]
Monica forgot to multiply by 1/2
The area of the fabric is 243 in.2

Explanation:
The formula for the area of a triangle is:
1/2 • base • height

Monica’s error is that she only multuplied the base and height, without multiplying 1/2 also.

The area of the fabric is 243 in.2 because:
1/2 • 18 • 27 = 243

Or you could just divide the wrong area Monica solved (486 in2) by 2. You will also get 243 in.2

tommy likes to run up and down and "up" escalator. Going up, he can cover 30 steps in 6 seconds. Going down, it takes him 15 sec
NemiM [27]

Answer:

3 steps per second.

Step-by-step explanation:

Find the Unit Rates of each going up and down:

--> 30/6 unit rate is 5 steps per second.

--> 30/15 unit rate is 2 steps per second.

Now subtract them to get the amount if the elevator wasn't moving:

--> 5-2= 3.

Please match each function formula with the corresponding transformation of the parent function y= -x^2-1
pishuonlain [190]

Answer:

The answer in the attached figure

Step-by-step explanation:

we have the parent function

y=-x^{2}-1

case 1) <u>Reflected across the x-axis</u>

we know that

The rule of the transformation is

(x,y)------> (x,-y)

so

y=-(-x^{2}-1)

y=x^{2}+1

case 2) <u>Reflected across the y-axis</u>

we know that

The rule of the transformation is

(x,y)------> (-x,y)

so

y=-(-x)^{2}-1

y=-x^{2}-1

case 3) Translated left by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x-1,y)

so

y=-(x+1)^{2}-1

case 4) Translated right by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x+1,y)

so

y=-(x-1)^{2}-1

case 5) Translated down by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y-1)

so

y=-(x)^{2}-1-1

y=-(x)^{2}-2

case 6) Translated up by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y+1)

so

y=-(x)^{2}-1+1

y=-(x)^{2}

What kind of triangle must have an altitude that is outside the triangle?
Tanya [424]

Answer:

'''For an obtuse-angled triangle, the altitude is outside the triangle. For such triangles, the base is extended and then a perpendicular is drawn from the opposite vertex to the base. For an obtuse triangle, the altitude is shown in the triangle below.'''
