Answer:

(-5,6)

Step-by-step explanation:

I graphed the points and found that (-5,6) would fall on the parabola.

The equation of the line is y=\frac{5}{9}(x+2)^{2}+1, if you need it.

QRST is a square. PQ = 2√ RU = 4<br> What is the length of SU? Round to the nearest tenth.
777dan777 [17]

Answer:

SU=3.5\ units

Step-by-step explanation:

step 1

In the isosceles right triangle PQT

PQ=PT ----> because is an isosceles triangle

Applying the Pythagoras Theorem

we have

PQ=PT =\sqrt{2}\ units

QT^{2}=PQ^{2} +PT^{2}

substitute the values

QT^{2}=\sqrt{2}^{2} +\sqrt{2}^{2}

QT^{2}=4

QT=2\ units

step 2

In the square QRST

RS=QT=2\ units

step 3

In the right triangle RSU

Applying the Pythagoras Theorem

RU^{2}=RS^{2} +SU^{2}

we have

RU=4\ units

RS=2\ units

substitute the values and solve for SU

4^{2}=2^{2} +SU^{2}

SU^{2}=4^{2}-2^{2}

SU^{2}=12

SU=2\sqrt{3}\ units

SU=3.5\ units

lex is saving money because she would like to purchase the new video gaming system that everyone has been talking about. After t
spin [16.1K]

Well one week she'd have 23.50$. So per week you multiply that number by the number of weeks.

I hope this is what you were looking for, the question was a bit confusing.

a line segment with points p(1 2) and q(4 3) is reflected across the line y=x. What are the new coordinates of the points of the
katen-ka-za [31]

Answer:

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)

Step-by-step explanation:

we know that

When you reflect a point across the line y= x, the x-coordinate and y-coordinate change places.

so

The rule of the reflection of a point across the line y=x is

(x,y) -----> (y,x)

we have

Points p(1,2) and q(4,3)

Applying the rule of the reflection across the line y=x

p(1,2) ------> p'(2,1)

q(4,3) -----> q'(3,4)

therefore

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)
