Answer:
x = 4√2
Step-by-step explanation:
<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>
To solve, we will follow the steps below:
using Pythagoras theorem
opposite² + adjacent² = hypotenuse²
14² + y² = 18²
196 + y² = 324
subtract 196 from both-side of the equation
196 -196 + y² = 324-196
y² =128
Take the square root of both-side
√y² = √128
y =√128
y = √64×2
y =√64×√2
y = 8√2
x = half of y
x = y/2
x = 8√2 ÷ 2
x = 4√2
Answer:
Step-by-step explanation:
Given
Required
Values of x that make it true
First: solve the inequality.
Collect Like Terms
Multiply both sides by -1
--- The inequality changes when multiplied by a negative value
So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)
Hence, the set is:
Let's do process of elimination
a) 2 is part of the set and 2 is not greater than 2. NO
b) 5 and 10 in the set are divisible by 5. NO
c) 2,4,6,8,10 are even but the rest are odd ( BUT note the word "or"). the rest are less than 12. YES
d) 0 and 1 are the only numbers that are neither prime nor composite (they're not even part of the set). NO
e) the square root of 9 is 3 so the maximum number is 9 (but what happened to 10?) NO
Answer: 15.2
Step-by-step explanation:
(14)^2 + (6)^2 = c^2
196 + 36 = c^2
232 = c^2
Square root both sides
15.231546 = c
15.2 ≈ c
