Answer:
4
Step-by-step explanation:
Translation means just move the object. It's not Dilation (2) not Reflection (1) not rotation (3)
so the answer is 4
To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=
, so to convert -40° to radians, we are going to multiply -40° by the conversion factor
; that way we can cancel degrees and express our answer in radians:
(-40°)
We can conclude that the correct answer is:

Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (2, 1), thus
y = a(x - 2)² + 1
To find a substitute (1, 0) into the equation
0 = a(1 - 2)² + 1
0 = a + 1 ( subtract 1 from both sides )
a = - 1
Hence
y = - (x - 2)² + 1 or
y = 1 - (x - 2)² → A
Answer: 1/8
Step-by-step explanation:
Hypotenuse = √97
One leg = 4
By Pythagoras theorem, second leg² = (√97)² - 4²
= 97 - 16 = 81
So second leg = 9
Area of triangle = 4 x 9 / 2 = 18 sq inch
One sq foot = 144 sq inch
So required fraction = 18/144 = 1/8
