A land surveyor places two stakes 500 ft apart and creates a perpendicular to the line that connects these two stakes. He needs
aksik [14]

Answer:

A perpendicular bisector is a perpendicular line that divides a line into two equal halves

step by step:

To apply the Perpendicular Bisector Theorem, the land surveyor will need to identify; the midpoint along the line connecting the two stakes

The reason why the surveyor needs to identify the midpoint is as follows:

According to the Perpendicular Bisector Theorem, all points on the perpendicular bisector of a line are of equal distance from the line's endpoint

In order to apply the perpendicular bisector, the surveyor would need to identify the midpoint from which the third stake can be placed 100 ft. along a perpendicular bisector drawn from the midpoint

Therefore, the surveyor needs to identify; the midpoint along the line connecting the two stakes

Someone knows how to do this?<br><br> Please, help me!
erica [24]

Answer:

a   K=2

b   A =200

c  B = ±2

Step-by-step explanation:

A = kB^2

When A =50 B=5

Substitute these values in

50 = k * 5^2

50 = k*25

Divide by 25

50/25 = k25/25

2 =k

A = 2B^2


When B = 10

A = 2*10^2

A = 2 *100

A = 200


When A =8

8 =2B^2

Divide by 2

8/2 = 2/2B^2

4 = B^2

Take the square root

±sqrt(4) = sqrt(B^2)

±2 = B

I need help with this math question
givi [52]

Answer:

a.) y = 3/(2ˣ)

b.) y = 1/(2ˣ)

c.) y = (π^π)ˣ

d.) y = (1/27)(1/√(3))ˣ

e.) y = .002908/(.119025ˣ)

f.) y = .00000004808/(.0413ˣ)

Step-by-step explanation:

Concept need to know is:

  • a negative exponent will flip the numerator with the denominator
  • a fraction as an exponent is just a root. so if the exponent is x^(1/2) then the root is 2 and x^(1/3) is a cube root
  • adding and subtracting exponent is the same thing as multiplying the same base.
  • so x^(1+2) = (x^1)(x^2)
  • and x^(1-2) = (x^1)(x^-2)
