What is the Quadratic Formula for y = x2 + 4x – 5

=================================================

Explanation:

Use a marker to highlight the first three digits on the left. That would be the 7, 0 and 0.

The digit just to the right of that second "0" is the digit "9". Since this 9 is larger than 5, we'll bump the 7.00 up to 7.01

The 0 in 7.01 is significant because it's between two nonzero values. So we have three sig figs here.

The dimensions for the width and height of the fish tank will be 4 feet and 2 feet .

Dimension is the measurable extent of a particular kind, such as length, breadth, depth, or height.

According to the given problem,

let , b = is the width of the fish tank

h = is the height of the fish tank given that , hold at least 35 cubic feet of water .

so ,

4×b×h ≥ 35

⇒ h ≥ 35/4b

now , surface area of the fish tank

⇒ 4b + 2× 4h + 2× bh

now substitute the value of h

here

⇒ ≥ 4b +70/b + 35/2

⇒ ≥ 40(70)^1/2 + 35/2 (if and only if b= (70)^1/2 / 2 , the equal sign holds )

therefore ,

= (70)^1/2 / 2 b ≈ 4.18 so b is 4 . when b = 4 ,

h = 35 / 4 × 4 = 2.1875 round off h = 2

so , the minimum surface area of fish tank is

⇒ 4×4+ 2× 4×2 + 2× 4×2⇒ 48

hence , the height and the width of the fish tank is 2 and 4 .

Step-by-step explanation:

Exterior angles thm:

5x - 10 + 3x + 14 = 100

8x + 4 = 100

8x = 104

x = 13

Answer:

t° = 11° s°= 71°

Step-by-step explanation:

79° + t° =90° (Given)

t°= 90° - 79°

t°= 11°

s°+79°+11°+19° =180° (angles on an str line)

s° = 180° - 109°

s° = 71°

Answer:

29.32

Step-by-step explanation:

We are given the diameter on the bottom, so we can find the radius. Since a radius is half the diameter, the radius is 2mi. The formula for the volume of a cone is:

1/3 * pi * r^2 * h

We can substitute:

1/3 * pi * 2^2 * 7

29.32153

This rounds to about 29.32

Answer:

V = 117.23

Step-by-step explanation:

V = (1/3) pi x r^2 x h

Input.

V = (1/3) 3.14 x 4^2 x 7

V = (1/3) 3.14 x 16 x 7

V = (1/3) 3.14 x 112

V = (1/3) 351.68

V = 117.23

Note: Please disregard my answer as I used the incorrect radius. I needed to find the correct radius instead of using the diameter as it was.

Answer:

Top right figure (the trapezoid)

Step-by-step explanation:

Line symmetry means that if you draw a line that cuts the figure, and reflect the figure across that line, the figure does not change.

Now, if we use vertical lines, a figure will have a line symmetry if it is exactly the same in the left as it is in the right.

And we can see that none of the figures meets this condition.

If instead, we use horizontal lines, then the figure must be equal above and below.

Particularly the "L" and the "t" can be discarded.

Also, the bottom right image can be discarded, as the bottom is clearly different than the top.

But the top right figure (the trapezoid) is exactly the same in the bottom as in the top, so if we reflect that image across a horizontal line that cuts it in two halves, the figure will not change, so that is the figure that has line symmetry,

Answer:

1.95

Step-by-step explanation:

area = (1/2 ×1 ×1 )×3 = 1.5 ( for sides)

area = ( 1/2 ×1 ×0.9) = 0.45 for base

area =1.5+0.45 = 1.95

Answer:

x = 9

Step-by-step explanation:

2x + 15 = 33

2x = 33 - 15

2x = 18

x = 18/2 = 9

Answer:

x=9

Step-by-step explanation:

2x+15=33

Subtract 15 from each side

2x+15-15=33-15

2x=18

Divide by 2

2x/2 = 18/2

x = 9

Answer:

£40

Step-by-step explanation:

3+5=8

160÷8= 20

20× 5=100

20×3=60

100-60=40

Answer:

£40

Step-by-step explanation:

160 shared between 3:5

3 + 5 = 8 (parts)

160 ÷ 8 = 20

20 = 1 part

Sue has 3 parts; (20 x 3) = £60

Oliver has 5 parts; (20 x 5) = £100

Work out how much more oliver get conpared to sue

oliver has £100, sue has £60

£100 - £60 = £40

oliver has £40 compared to sue

P=2l+2w

l+w equals half of the perimeter

220/2=110

the ratio of the length to the width is 7:3

7x+3x=110

10x=110

x=11

7*11=77 for the length

3*11=33 for the width

A=l*w

A=77*33

A=2541 square inches for the area

maybe you are getting the formula mixed up ?!?!
