Given:
Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.
To find:
The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.
Solution:
If a figure is dilated by factor k with origin as center of dilation, then
Where, 0<k<1 is reduction and k>1 is enlargement.
The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:
Using this rule, we get
Therefore, the new coordinates of point S' are (8,-4).
so the missing term in the denominator is 7^(-22)
ok done. Thank to me :>
To write a line that is perpendicular you have flip the slope and change the sign so it would be -1/2, then you carry on like normal. So the answer is:
y-6= -1/2(x-9)
I am sorry if i am wrong but i am getting c or d
95% confidence interval is given by
x - 2D , and x+ 2D
For 99% confidence interval is
x - 3D , and x + 3D
x = 100000
D = 2000
Then calculate
100000 - 3•2000= 94000
and
100000 + 3•2000= 106000
Now find √D = 44.72
Then interval is
100000 - 44.72 ,. And. 100000 + 44.72
99,956 lower limit and. 100472 upper limit
Then we see that theres only one interval ,
that is between thes 2 limits
ANSWER Is OPTION C) ) ($99.996.46, $100,003.55)
