Answer:
Angle measure two is equal to 75º and Angle measure one is equal to 105º
Step-by-step explanation:
I know this because angle one is alternate exterior angle with angle 7 and angle seven forms a staight line with angle 75 so to find angle 7 you have to do 180-75 and that would equal 105.
for angle two it is interior angles with angle 75 so this means that are congruent angles which means they both have the same measure
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
Answer:
ONE: x = 10
Step-by-step explanation:
3x + 6 = -1 - 3 + 4x
3x + 6 = -4 + 4x |subtract 6 from both sides
3x = -10 + 4x |subtract 4x from both sides
-x = -10 |change the signs
x = 10
Answer:
1089
Step-by-step explanation:
The original number is A0CD, We have that DC0A = 9 x A0CD.
If A =1, then D = 9 and we have:
9C01 = 9 x 10C9
In order for this expression to be true, the following must also be true:
(C x 9) + 8 must be divisible by 10, which means that C x 9 must end in a 2.
The only multiple of 9 (from 9 to 81) that ends in a 2 is 72.
72 = 9 x 8.
Therefore, C must be 8 and the original number is 1089. Multiply it by 9 to check the answer:
1089 x 9 = 9,081
Therefore, 1089 is correct.
