280 divided by 7 equals 40 and forty times 12 equals 480 so the answer is 480
ANSWER
The vertex of the graph of

is

EXPLANATION
The vertex form of a parabola is given by

where

is the vertex of the parabola.
The function given to us is

This is already in the vertex form.
When we compare this to the general vertex form, we have,


and

Therefore the vertex of the parabola is

Hence the correct answer is option A.
Answer:
Perimeter of the polygon p = 24
Step-by-step explanation:
Step(i):-
Given the vertices of a polygon are
P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)
The distance of PQ

The distance of QR

The distance of RS

The distance of PS

<u><em>Step(ii):-</em></u>
Perimeter of the polygon
= sum of all sides of polygon
p = a+ b+ c+ d
p = 5+7+5+7
p = 24
<u><em>Final answer:-</em></u>
Perimeter of the polygon p = 24
Answer:
5
Step-by-step explanation:
Because -5 is a negative number and the opposite of negative is positive and 5 is positive.
Answer:
a). -5.7 meters or 5.7 meters below sea level
b). When we combine the two depths we sum them since they are an increment in the same direction and we sum them from the seal level, our first reference point.
Step-by-step explanation:
a). Final depth=Initial depth+deeper increment=(-1.5)+(-4.2)=-5.7
Initial depth=-1.5 represented by a negative number since she is below sea level, meaning her reference point(point 0) is the sea level. The more she moves below the sea level the deeper she goes and the more her depth becomes negative
Deeper increment=-4.1, she further moves deeper from her initial depth(-1.5) by a value of -4.1. In order to find her final depth, we have to sum all the depths she covered from her first reference point which is the see level.
The expression is;
Final depth=Initial depth+deeper increment=(-1.5)+(-4.2)=-5.7 meters
Her final depth=-5.7 meters
b). When we combine the two depths we sum them since they are an increment in the same direction and we sum them from the seal level, our first reference point.
