Answer:
XY is a tangent
Step-by-step explanation:
Given
Required
Is XY a tangent?
XY is a tangent if:
Because XY should make a right angle at point X with the circle
Where
So, we have:
This gives:
<em>Yes, XY is a tangent</em>
Answer:
x= 14/9 = 1 5/9
Step-by-step explanation:
Use the distributive property to multiply 2 by 5x−3.
2(5x−3)−4=x+4
Subtract 4 from −6 to get −10.
10x−6−4=x+4
Subtract x from both sides
10x−10=x+4
Combine 10x and −x to get 9x.
10x−10−x=4
Add 10 to both sides.
9x−10=4
Divide both sides by 9.
x= 14/9

Answer:
Solution 1: 1+1
Solution 2: 1-
Step-by-step explanation:
x^2-2=2x
x^2-2x-2=0
Use quadratic equation.
(-b+-
)/2a
(2+-
)/2
(2+-
)/2
(2+-
)/2
Solution 1: (2+2)/2=1+1
Solution 2: 1-
the picture in the attached figure
we know that
area of the triangle is equal to
in this problem
A=47 in²
b=x
h=x
so
therefore
the answer is
x=9.7 in
Answer: The speed of the motorboat is 70 miles per hour
Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.
For example, at 2 hours, the distance shown on the graph is 175 miles
Subtract: 175 -35 = 140. Then divide 140/2 = 70
At 4 hours, the distance shown is 315 miles.
Subtract: 315 - 35 = 280. Then divide 280/4 = 70
70 mph is the speed.
