Corrected question;
! The regression equation y = 3.648 • 1.182^x approximates the cost to go on a safari, y, given the number of years since it opened in 2005, x. Which is the best estimate for the cost of a vehicle to drive through the safari in 2011?
Step-by-step explanation:
Given;
The regression equation
y = 3.648 • 1.182^x
Where;
x = number of years since it opened in 2005
y = the cost to go on a safari
For this case;
x at 2011 = 2011 - 2005
x = 6 years
Substituting into the regression equation;
y = 3.648 × 1.182^(6)
y = 9.948547753694156132352
y = $9.95
Answer:
it is right triangle so we have trigonometric ratio: tan(54)=3/x and from that we have x=3/tan(54)
Answer:
b.
Step-by-step explanation:
We are given that
Length of equilateral triangle=a=18 in
Base of oblique pyramid is an equilateral triangle.
We have to find the height of the triangular base of the pyramid
Height of the triangular base of the pyramid,h=
We know that each angle of equilateral triangle =60 degree

Substitute the values
Height of triangular base of the pyramid,h=
in
Using the value of

Height of triangular base of the pyramid,h=
