define
W= width <span>playhouse real=3.5
H= height </span>playhouse real
x=width playhouse model
y=height playhouse model
therefore
H/W=y/x------------------>H=y*W/x------------>H=3.5*y/x
The answer is 3.5*y/x to find the height H
Answer (3+6)(3x-4) sorry bad photo and hand writing
Answer: x=6.7016 I hope this will help
Step-by-step explanation: STEP 1.
Isolate the square root on the left hand side
Radical already isolated
√5x-1 = x-1
STEP 2.
Eliminate the radical on the left hand side
Raise both sides to the second power
(√5x-1)2 = (x-1)2
After squaring
5x-1 = x2-2x+1STEP
Step 3.
Solve the quadratic equation
Rearranged equation
x2 - 7x + 2 = 0
This equation has two real roots:
x1 = ( 7 + sqrt( 41) ) / 2 = 6.7016
x2 = ( 7 - sqrt( 41) ) / 2 = 0.2984STEP
Step 4.
Check that the first solution is correct
Original equation
√5x-1 = x-1
Plug in 6.7016 for x
√5•( 6.7016) -1 = ( 6.7016) -1
Simplify
√32.508 = 5.702
Solution checks !!
Solution is:
x = 6.7016 STEP
Step 5.
Check that the second solution is correct
Original equation
√5x-1 = x-1
Plug in 0.2984 for x
√5•( 0.2984) -1 = ( 0.2984) -1
Simplify
√0.492 = -0.702
Solution does not check
0.702 ≠ -0.702
The <em>correct answers</em> are:
#1: 44°; #2: 74°
Explanation:
#1) Since ∠O = 136°, the intercepted arc is also 136°. This means the other arc is 360-136=224°. The measure of an angle formed by two tangents is half of the difference of the intercepted arcs; this is 1/2(224-136) = 1/2(88) = 44°.
#2) Point Q is tangent to the circle, and forms a 90° angle with the radius at that point. Point P = 16°. The three angles together form a triangle, which has a sum of 180°. This means the missing angle is equal to 180-(90+16) = 180-106 = 74°.
