<h3>Answer: Choice A</h3>

Explanation:

The square root undoes the squaring operation.

Think of a square that is 1 ft by 1 ft. Its area would be 1*1 = 1 sq ft.

Now imagine you told your friend "the area is 1 sq ft" and you didn't relay the side lengths. Your friend would use the square root to find the side length is 1 ft.

I'm not sure why your teacher is using plus minus notation when that is not correct. Saying \sqrt{1} = \pm 1 is not true. The result of a square root is simply one value only. If your teacher meant \pm \sqrt{1} = \pm 1, then it would be a true statement; however, there's no need to involve negative numbers for this problem.

Find the quotient if the dividend is 2.26 · 108 and the divisor is 0.013.
Sliva [168]

Answer:

17.38*10^8

Step-by-step explanation:

Step one:

given data

The  dividend is 2.26*10^8 (i rewrote the given data, i hope it was mearnt to be so)

divisor is 0.013.

Step two:

Hence the quotient is the whole number gotten when the dividend is divided by the divisor

quotient= 2.26*10^8/0.013.

quotient= 17.38*10^8

At what point does a line with a slope of 34 and a y-intercept of -5 intersect a line with a slope of −14 and a y-intercept of 3
maw [93]
Set them into slope-intercept forms of equations then set those equations equal to each other and solve for x and y.  y = 34x - 5 and y = -14x+3.  Set those equal to each other, solve for x to get x = 1/6.  Sub in that x value to get y = 2/3.  The point where they intersect is the solution of the system; in other words, where on both lines we have the exact same (x, y) value.

Find the equation of the tangent line and normal line to the curve y=(6+4x)2 at the point (6,900). Write the equations of the li
Ksenya-84 [330]

Answer:

Equation of the tangent to the curve

y = 240x - 215994

Equation of the normal

y = (-1/240)x + 9.75 = - 0.00417x + 9.75

Step-by-step explanation:

y = (6 + 4x)² = 36 + 48x + 16x² = 16x² + 48x + 36

dy/dx = 32x + 48

At the point (6,900),

dy/dx = 32(6) + 48 = 240

Equation of the tangent at point (a,b) is

(y - b) = m(x - a)

a = 6, b = 900, m = 240

y - 6 = 240(x - 900)

In the y = mx + b form,

y - 6 = 240x - 216000

y = 240x - 215994

The slope of the normal line = -(1/slope of the tangent line) (since they're both perpenducular to each other)

Slope of the normal line = -1/240

Equation of normal

y - 6 = (-1/240)(x - 900)

y - 6 = (-x/240) + 3.75

y = (-1/240)x + 9.75

y = - 0.00417x + 9.75
