Answer:

Step-by-step explanation:

So consider the following:

let's say that we only have the 3 people, the kid, the mother and father.

So you have this equation: 2*1*1

then you add in the 4 other people so you have the final equation:

4*3*2*1*2*1*1 which equals 48.

Hope this answer helped.

. Write the following exponential expressions as equivalent radical expressions. <br> a. 2^(1 /2)

Andrei [34K]

Answer:

So $2^{\frac{1}{2}}$ will be equivalent to $\sqrt{2}$ in radical form

Step-by-step explanation:

We have given expression $2^{\frac{1}{2}}$

We have to write this in radical form

We know that if any fraction is in exponential form then if we write this in radical form then in radical form the exponent come inverse of its number

So $2^{\frac{1}{2}}$ can be written in radical form as $\sqrt{2}$

So $2^{\frac{1}{2}}$ will be equivalent to $\sqrt{2}$ in radical form

Find the coordinates of the points of intersection of the graphs with coordinate axes: y=− 1/4 x+2

bearhunter [10]

Answer:

Step-by-step explanation:

Here, you can use a simple formula.

To find the point of intersection you just put x=0 or y=0.

Because, if a graph intersects x-axis, then at this point y=0

Similarly, if a graph intersects y-axis, then at this point x=0

So, for our given line.

y=-1/4 x +2

when , x=0 , y=-1/4 (0)+2=2

So, the graph intersects y-axis at y=2

when , y=0 ,

then 0=-1/4 x+2

or, 1/4 x=2

or, x=8 [multiplying by 4]

So, the graph intersects x-axis at x=8

Please help (the question is in the attached image)

Answer:

a.the length of midsegment of an equilateral triangle with side lengths of 12.5 cm.=12.5/2=6.25cm

sinceUT is the perpendicular bisector of line segment AB, where T is on AB, find the length of AT given AT = 3x + 6 and TB = 42 - x.

than AT=BT

3x+6=42-x

3x+x=42-6

x=36/4=9

AT=3×9+6=27+6=33

since angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

EH=GH

5y+10=28-y

6y=28-10

y=18/6=3
