Step-by-step explanation:

For observers right at the north pole and the south pole, there are only two seasons – an almost six-month long winter night followed by an almost six-month long summer day!

I believe the answer is winter since seasons are reversed at the poles and it’s summer while the South faces the sun so reverse and it would be winter

What is the equation of the circle that has a center at (-3, 1) and a radius of 5? A) (x + 3)2 + (y - 1)2 = 5 B) (x - 3)2 + (y +

Gnoma [55]

Answer:

Step-by-step explanation:

The vertex form of the equation of a circle is $(x-h)^2 + (y-k)^2 = r^2$ where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes $(x--3)^2 + (y-1)^2 = 5^2$ . This simplifies to $(x+3)^2 + (y-1)^2 = 25$ . The solution is C.

please solve the question and show your work find the missing number in 34x =0 show how u got your answer and write full explana

Anastaziya [24]

34x=0
So we need to isolate x. Since 34 is multiplied by x, we need to isolate x by moving 34 over the equal sign. Whenever you move something over the equal sign, the opposite is done. For 34, instead of being multiplied, it will be divided.
34x=0
X=0/34
Then you solve for x
X=0
Hope this helps!

A company wishes to manufacture a box with a volume of 36 cubic feet that is open on top and is twice as long as it is wide. Fin

Nimfa-mama [501]

Answer:

Width is 3 ft

length is 6 ft

Step-by-step explanation:

Let x = the width

Let 2x = the length

Let h = the height

We know that volume is given v = l×b×h

so we have v = volume $= x*2x*h$

$2x^2*h = 36$

$h = \frac{18}{x^2}$

surface area include 2 ends + 1 bottom and 2 sides excluding top

$S.A. = 2(x*h) + 1(2x*x) + 2(2x*h)$

$S.A. = 2xh + 2x^2 + 4xh$

we have calculate $h = = \frac{18}{x^2}$

$S.A = 2x^2 + 6x \frac{18}{x^2}$

$S.A = 2x^2 + \frac{108}{x}$

By graphing above equation we can calculate the value of x

Minimum S.A when x is 3 is the width so

2(3) = 6 is the length

$h = \frac{18}{3^2} = 2$

21. 0.25x - 1.25 - 3x + 2 = -2.75x + 0.75
22. 15/100= 0.15. 0.15•64,000= 9,600. The answer is D.
23. 1,200-300= 9,000. 1,200+300= 15,000. 9,000/15,000= 3/5. 3/5= 0.6. 60% of the building is aboveground.
24. The patterson seems to be the y=18x and when you plug 7 in to the equation, you get 126, not 128, so D is the answer.
