Answer:
the point lies at (1.7, 3.6) in the first quadrant.
Step-by-step explanation:
The formula for a circle with centre (h,k) and radius (r) can be expressed as :
(x-h)² + (y-k)² = r²
Now for the expression of the circle with radius 3 and center (0,1), we have:
(x - 0)² + (y - 1)² = 3²
x² + (y-1)² = 9
replacing y = 1.5x + 1 in the above equation, we have:
x² + (( 1.5x + 1 ) - 1 )² = 9
x² + ( 1.5x +1 - 1)² = 9
x² + (1.5x)² = 9
x² + 2.25x² = 9
3.25x² = 9
x² = 9/3.25

![x= \sqrt{{9} \times {\dfrac{4}{13}}}](https://tex.z-dn.net/?f=x%3D%20%5Csqrt%7B%7B9%7D%20%5Ctimes%20%7B%5Cdfrac%7B4%7D%7B13%7D%7D%7D)

x = 1.7 in the positive x - axis
Recall that:
y = 1.5x + 1
y = 1.5 (1.7) +1
y = 2.55 +1
y = 3.55
y = 3.6
Therefore, the point lies at (1.7, 3.6) in the first quadrant.
Answer:
divide 150 by 12 ( because there are 12 inches in one foot) and your answer would be 12.5 feet.

Answer:
negative number
Step-by-step explanation:
negative numbers are the opposite of real numbers . for example
-5 -4 -3 -2 -1 0 1 2 3 4 5
The length of rectangle is 44 yards and width of rectangle is 20 yards
<em><u>Solution:</u></em>
Let the length of rectangle be "a"
Let the width of rectangle be "b"
<em><u>Rectangle has a length that is 4 more than twice the width</u></em>
Length = 4 + 2(width)
Length = 4 + 2b
The perimeter is 128 yards
<em><u>The perimeter of rectangle is given by:</u></em>
Perimeter = 2(length + width)
128 = 2(4 + 2b + b)
128 = 2(4 + 3b)
Divide both sides by 2
64 = 4 + 3b
3b = 60
b = 20
<em><u>Substitute b = 20 in length</u></em>
Length = 4 + 2(20)
Length = 4 + 40 = 44
Thus length of rectangle is 44 yards and width of rectangle is 20 yards
