Sin ( theta ) = opposite / hypotenuse
sin ( 37° ) = 13 / x
Answer:
60 ft²
Step-by-step explanation:
The reason being that you take the height of 8 and multiply it by the width of 15. 8×15=120 Then since a triangle is half of a square you would halve it. 120÷2=60 Which would then give you your answer.
Answer:
.....................................................
The multiplier you would use to find the new value would be 0.4.
The reason for this is that 100%-60% =40%. This is the part of the value it will keep. 40% is the same as 0.4.
This decimal represents the part of the original price that is it still worth.
The multiplier is 0.4 because that it what you would multiply $80 by to find the new value.
Using the numbers in the given equation:
a =-2, b = 6 and c = -5
The vertex form is written as : a(x+d)^2 + e
we need to find d and e:
d = b/2a = 6/2(-2) = -3/2
e = c-b^2/4a = -5 - 6^2/4(-2) = -1/2
Now substitute the letters for their values in the vertex form formula above:
-2(x-3/2)^2 -1/2
The vertex is (3/2, -1/2)
2. The formula begins with a negative number ( -2) so the Parabola opens downwards.
3. To find the intercept replace x with 0 and solve for y:
the intercept is (0,-5)
