Answer:

They didn't give the needed amount of evidence but let's just say it's 1/2 in width, it would then be 1/2x5/2=1 1/4 then multiply that by 27/5x1 1/4 to get 6.75! There fore the volume of the shape is 6 3/4 units other wise known as 6.75 units! Hope this helped! :D

What is the Turing point of f(x)=x^2-2x+8

netineya [11]

Method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)

method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7

Answer:

Answer:

For converging lens

object distance u = - 2.0cm

Focal length f = 5.0cm

From lens formula

Size of image = size of object x Magnification

= 2 x .10 = 2.0cm

For diverging lens

object distance u = 140 - 120 = 20 cm

focal length f = -30 cm

frac{1}{v}+\frac{1}{20}=-\frac{1}{30}

v = -12 cm

m = 12/20 = 0.6

size of final image = .6 x 30 = 18 cm

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year

SashulF [63]

Answer:

640 foxes

Step-by-step explanation:

The actual formula is $y = 40 * 4^{x}$

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

$y = 40 * 4^{x}$

$y = 40 * 4^{2}$

$y = 40 * 16$

$y = 640$

Finally, we can see that there should be 640 foxes after 26 years.

Enya is building a storage cupboard in the shape of a rectangular prism. The rectangular prism has a square base with side lengt

Gnesinka [82]

The amount of paint required to paint the whole cupboard is:

$2\times2.5^2+4\times(2.5\times3.5)
\\=47.5 ft^2$

The amount of paint required to paint all but the bottom surface is:

$2.5^2 + 4(2.5\times3.5)
\\= 41.25 ft^2$

So the difference in paint required is 6.25 square feet worth of paint.
