Answer:
1.
Step-by-step explanation:
The thing is, x^0 is always 1. So even if you simplify, it will still be 1.

Answer:
Answer is A(-3/4, 1/4), B(1,3/4), C(1/2,3/4) D(1/4,1)
Step-by-step explanation:
From the attached diagram, the coordinates are:
A(-3,1), B(4,-3), C(2,3), D(1,4)
The image is gotten by dividing the coordinates by the scale factor 4 to get the above answer
Given

We have to set the restraint

because a square root is non-negative, and thus it can't equal a negative number. With this in mind, we can square both sides:

The solutions to this equation are 7 and -2. Recalling that we can only accept solutions greater than or equal to -1, 7 is a feasible solution, while -2 is extraneous.
Similarly, we have

So, we have to impose

Squaring both sides, we have

The solutions to this equation are 5 and 10. Since we only accept solutions greater than or equal to 7, 10 is a feasible solution, while 5 is extraneous.
Answer:

Step-by-step explanation:
step 1
Find the length side PQ
we know that
The area of rectangle PQRS is given by


so

substitute the value of QR

solve for PQ

step 2
Find the length side AB
we know that
The perimeter of rectangle ABCD is given by

we have

substitute

solve for AB

Answer:
C = π(6)
C = 6π
C = 18.84
Step-by-step explanation:
The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. The information given is the diameter so use C = πd by substituting d = 6.
C = π(6)
C = 6π
C = 18.84
