Equation of Circle:
Center(h,k) radius(r)
(x-h)^2 + (y-k)^2 = r^2
#14
C(0,0) r = 2
(x-0)^2 + (y-0)^2 = 2^2
x^2 + y^2 = 4
#15
C(2,0) r = 3
(x-2)^2 + (y-0)^2 = 3^2
(x-)^2 + y^2 = 9
...
Answer:
The side lengths of the image after the dilation = 13.5 cm and 20.25cm
Step-by-step explanation:
A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.
Dilation can also be referred to as scale factor
6cm × 2.25 = 13.5 cm
9 cm × 2.25 = 20.25 cm
The side lengths of the image after the dilation = 13.5 cm and 20.25cm
W>10. 80-2w>50 subtract 80 on both sides and then divide by negative two.
Answer:
-10.2n - 1
Step-by-step explanation:
−2.4n − 3 + (−7.8n + 2) =
= -2.4n - 7.8n - 3 + 2
= -10.2n - 1
Volume of rectangular prism = length * width * height
Volume of triangular prism =( length * height * base )/2
Given,
Volume of rectangular prism = 18 + volume of triangular prism
18x = 18+14x
4x=18
x= 4.5 ft
So volume of rectangular prism = 6* 4.5* 3 = 81 ft³
Volume of triangular prism = (7* 4.5 * 4) / 2 = 63 ft³
