Answer:
Area of the trapezium = 30
Step-by-step explanation:
a = 14
b = 4
h= 5
Area of trapezium = ( a + b) h = (14+4) 5
= x 18 x 5 = 6 x 5 <em> [I solved </em><em> and 18]</em>
= 30!
We will evaluate Martin's work step by step:
Step 1:
f (x) = sinA,
where
A = arctan x
and
x = tanA
step 1 it's OK
Step 2:
tanA = opp / adj = x / 1
step 2 it's OK
Step 3:
hypotenuse = square root of 1 ^ 2-x ^ 2 = square root of 1-x ^ 2
step 3 it's NOT OK
The correct form in this case is:
hypotenuse = square root of 1 ^ 2 + x ^ 2 = square root of 1 + x ^ 2
Answer:
Martin did make his first mistake in Step 3.
Answer:
The answer is 1
Step-by-step explanation:
Formula for finding the slope:
Take y2 and y1 from (4,<u>4</u>) (1,<u>1</u>)
Take x2 and x1 from (<u>4</u>,4) (<u>1</u>,1)
This is how the answer is 1
Hope it helps :)
