Answer:
-2
Step-by-step explanation:
7 +7= 14. 14 + -2 = 12
Answer:
L' = 26cm
W' = 39cm
Step-by-step explanation:
a) Given the dimension of the shape;
length L = 10cm
Width W = 15cm
After dilating by a scale factor os 2.6
New length L' = 2.6(10) = 26cm
New width = W' = 2.6(15) = 39cm
Hence the length of each sides of the dilated image are 26cm and 39cm
b) The new image will be similar to the given image but of with the resulting length gotten in (a).
Dy/dx= tanx, can be answered directly using the derivatives of trigonometric functions but this is how the answer is derived
=(sinx/cosx) basic trigonometric function
= [cosx cox+sinxsinx]/cos^2x
=[cos^2x+sin^2x]/cos^2x
cos^2+sin^2x = 1 ; fundamental trigonometric identities
= 1/cos^2x; reciprocal relations
= sec^2x+C
The answer is letter B.sec^2x+C
