Answer:
is this further maths?
Step-by-step explanation:
Could you explain what the question means into an equation?
Answer:
24.08
Step-by-step explanation:
We use the Pythagorean theorem and we get (16)^2 + (18)^2 = (x)^2
256 + 324 = x^2
x^2 = 580
x is about 24.08.
C = 8 x pi
C = 8 x 3.14
C = 25.12
Answer:
m ∠ 1 = 60°
Step-by-step explanation:
When 2 lines are parallel and are crossed by another line known as transversal line the angles in matching corner is known as corresponding angles . In this case when the two lines are parallel, corresponding angles are equal. This means angle 60 ° is the same as the angle on the second line which is opposite to the ∠1 .
Angle on a straight line = 180°
so the angle that runs on that second parallel line is 180° . The angle on the other left side = 180 - 60 = 120°.
The total angle on a straight line of that transversal line = 180° The angle 1 can be gotten when you subtract 120 ° from 180° = 60°.
Therefore,
m ∠ 1 = 60°
Or
You can just say 60° is an alternate exterior angle to m∠1 .
F(x)=2x²+18x+16
1) we have to calculate the first derived.
f´(x)=4x+18
2) Now, we equalize the first derived to "0" and find out the value of "x"
4x+18=0
4x=-18
x=-18/4=-4.5
3)we calculate the second derived
f´´(x)=4>0 ⇒we have a minimum at x=-4.5
4) Now we calculate the value of "y".
f(-4.5)=2(-4.5)²+18(-4.5)+16=40.5-81+16=-24.5
Therefore; Exist a minimum at (-4.5 , -24.5)
