Solution:
In order to find ,we need to plugin input=2 i.e. the value of in the function and find the output by evaluating.
Plugging in in the given function.
Evaluating.
∴ (Answer)
Step-by-step explanation:
well,
(y - 7)² = (y - 7)(y - 7)
remember how to multiply 2 expressions ?
you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).
so, when we do the multiplication, we get
(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =
= y² - 14y + 49
and that is clearly different to y² - 49
FYI
y² - 49 is the result of
(y - 7)(y + 7)
because
y×y + 7×y - 7×y + (-7)(7) = y² - 49
70℅ = 14
100 = X
70X = 1400
X = 1400/70
X = 20
20 Euros is the full price
The probability of drawing the initial Jack is 4 out of 52 as there are 4 Jacks in deck of 52 cards. Since you are not replacing the Jack the Deck now has 51 cards and 3 Jacks making that 3 out of 51
Answer:
B. The maximum occurs at the function's x-intercept.
Step-by-step explanation:
Given table:
From inspection of the table, we can see that:
- and
This indicates <u>symmetry</u>.
The line of symmetry is the mid-point between the two x-values.
Therefore, the <u>line of symmetry</u> is x = -4
The vertex (minima/maxima) is on the line of symmetry, therefore the vertex is at (-4, 0). As the function decreases as x → 0, the vertex is a <u>maximum</u>.
As the y-value of the vertex is 0, the maximum occurs at the function's <u>x-intercept</u>.
