Solve four square root of two plus five square root of four and explain whether the answer is rational or irrational. The answer

Rina8888 [55]

Answer:

A.The answer four square root of two plus ten is irrational because the sum of a rational number and irrational number is an irrational number.

Step-by-step explanation:

Given the question as 4√2 + 5√4 the sum is

4√2 + 5*√4

4√2 + 5*2

4√2 + 10

Putting an irrational number in decimal form, it goes on forever without repeating.

4*√2 +10 = 4× 1.41421356237 +10

If Gina leaves now and drives at 66km/h she will reach Alton just in time for her appointment on the other hand if she has lunch

Stolb23 [73]

Answer:

165km

Step-by-step explanation:

If Gina leaves now and drives at 66km/h she will reach Alton just in time for her appointment

Now:

Distance=Speed X Time

D=66 X t=66t.....(I)

If she leaves in 40 minutes,and she must get there at the same time, her new drive time will be:

t hours - 40 minutes

=(t-40/60)hours=( t-2/3) hours

Her Distance this time

D=90(t-2/3)=90t-60.....(ii)

Since the distance to Alton does not change, we equate (I) and (ii)

66t=90t-60

60=90t-66t

60=24t

t=2.5 hours

From equation (I)

Distance=66t=66X2.5=165km

Distance to Alton is 165km.

The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis

pantera1 [17]

Answer:

Step-by-step explanation:

<u>Reflection across the x-axis</u>

Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.

We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:

P'(3,-7) Q'(7,6) R'(-8,-7).

The new triangle has vertices P'Q'R'.
