Answer:
the equation of the axis of symmetry is 
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form:
, being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form:
, is given by:

which in our case becomes:

Then, the equation of the axis of symmetry for this parabola is:

Round to 4,800 because 2 &It;5.
Answer/Step-by-sep explanation:
1. Given:
∆NMK ≅ ∆TRP




a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP
b. The side that is congruent to
is
. Thus:
≅ 
c. Since
≅
, therefore:

(substitution)
Add 1 to both sides


Divide both sides by 3


2. a. Slope of LK = 
Slope of LM = 
b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):






✍️Length of LM is the distance between L(-7, 4) and (-2, 1):





(nearest tenth)
∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.
Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.
Answer:
quarts
12 days
Step-by-step explanation:
Given that:
Amount of water leaked in 4 days = 3 quarts
To find:
Number of quarts leaked in 1 week?
Number of days taken for the leakage of 9 quarts of water?
Solution:
We can simply use unitary method or the ratio to find the answers of the questions asked in the statement.
As per question statement:
Amount of water leaked in 4 days = 3 quarts
Dividing by 4 on both sides:
Amount of water leaked in 1 day =
quarts
Multiplying by 7 on both sides:
Amount of water leaked in 7 days =
quarts
Number of days taken for the leakage of 3 quarts = 4 days
Multiplying by 3 on both sides:
Number of days taken for the leakage of 3
3 = 9 quarts = 4
3 = <em>12 days</em>
Answer:
D
Step-by-step explanation:
Stan works for 28 hours and gets paid $12 for each hour, so the amount of money he gets in total is $12*28 = $336.
