Answer:
False
Step-by-step explanation:
Because a translation can increase or decrease both the x and the y.
O = 7*180 = 1260 degrres
sin O = 0
A right angle = 90 degrees
A round angle = 360 degrees
1. 3 x 90 = 270 degrees
2. 4 x 90 = 360 degrees
3. 1 1/2 x 90 = 135 degrees
4. 2 1/3 x 90 = 210 degrees
5. 2/9 x 360 = 80 degrees
6. 3 3/8 x 360 = 1,215 degrees
Answer:
(0, - 3 ) and (- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 4x² + 6x - 3 → (1)
y = 2x - 3 → (2)
Substitute y = 4x² + 6x - 3 into (2)
4x² + 6x - 3 = 2x - 3 ( subtract 2x - 3 from both sides )
4x² + 4x = 0 ← factor out 4x from each term
4x(x + 1) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 0 : y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )
x = - 1 : y = 2(- 1) - 3 = - 2 - 3 = - 5 ⇒ (- 1, - 5 )
The formula for circumference is
or
. We have a diameter for the semicircle, so let's use the diameter formula.
which is either
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
