A(7, −3), B(9, 7) (a) Find the distance d(A, B) between A and B. (Round your answer to two decimal places.) d(A, B) =

insens350 [35]

Answer:

≈ 10.20

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(7, - 3) and (x₂, y₂ ) = B(9, 7)

d = $\sqrt{(9-7)^2+(7+3)^2}$

= $\sqrt{2^2+10^2}$

= $\sqrt{4+100}$ = $\sqrt{104}$ ≈ 10.20 ( to 2 dec. places )

Which equation can be simplified to find the inverse of y = x2 - 7?

Solnce55 [7]

Answer:

The inverse is

$y = \pm \sqrt{ {x}^{2} - 7 }$

Step-by-step explanation:

The options are not provided.

However, I will show you how to find the inverse of

$y = {x}^{2} - 7$

We interchange x and y to get,

$x = {y}^{2} - 7$

We solve for y,

${y}^{2} = x + 7$

$y = \pm \sqrt{x + 7}$

PLEASE BE QUICK: I'm terrible at math, but my god someone help, this is my last try on this assignment, and trust me all the poi

For prisms, use the formula: 2B + Ph

B = base of figure, here it is the trapezoid.
The area of the trapezoid is (3+6)*4/2 = 18

P = perimeter of the base, which is 3+4+5+6 = 18
h = height, here it is 5.

Thus the answer is:
2*18 + 18*5 = 36 + 90 = 126 cm^2
