m∠6 = 130°
Step-by-step explanation:
Answer:
y = 2x^2 +1
Step-by-step explanation:
This is a parabola so it is in the form
y = a( x-h) ^2 + k
where ( h,k) is the vertex which is at ( 0,1)
y = a (x - 0)^2 + 1
y = ax^2 +1
Pick another point on the graph to determine a
(1,3)
3 = a(1)^2 +1
Subtract 1 from each side
3-1 = a(1)
2 =a
y = 2x^2 +1
Answer:
Step-by-step explanation:
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
see the attached figure to better understand the problem
so
∠DEF=∠ECD+∠CDE
substitute the given values
solve for x
Combine like terms
Group terms
Find the measure of angle CDE
substitute the value of x
60 seconds are in each minute. To find the number of seconds in 35 minutes, you multiply 60 (seconds) by 35 (minutes.) The answer is 2,100 seconds.
