Answer:
y = (x - 7)² - 9
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k ) are the coordinates of the vertex and a is a multiplier
given
y = x² - 14x + 40
to obtain vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 14x
y = x² + 2(- 7)x + 49 - 49 + 40
= (x - 7)² - 49 + 40
= (x - 7)² - 9 ← in vertex form
Answer:
3/2
Step-by-step explanation:
3(2)^-1 --> 2^-1 = 1/2 --> 3(1/2) --> 3/2
59,425 sq mi
When you want to round to the units place, you look at the digit in the number that is in the place to the right of that: the tenths place. Here, that digit is 7, which is more than 4. Because that digit is more than 4, 1 is added to the units place and all the digits to the right of that are dropped.
This gives you 59,424 +1 = 59,425.
If the tenths digit were 4 or less, no change would be made to values in the units place or to the left of that. The tenths digit and digits to the right would be dropped.
... 59,424.3 ⇒ 59,424 . . . . . for example

Answer:
∠ ACD = 70°
Step-by-step explanation:
The angle on the circle subtended by arc AB is half the angle at the centre subtended on the same arc, that is
∠ ACD = ∠ AOB = × 140° = 70°
