Answer:
A is correct, x=7, AB=20
Step-by-step explanation:
All of the options say x=7 so you can just input 7 into 4x-8 to find AB
4(7)-8=AB
28-8=AB
20=AB

Recall that for all t,
cos²(t) + sin²(t) = 1
Now,
x = 5 cos(t) - 7 ⇒ (x + 7)/5 = cos(t)
y = 5 sin(t) + 9 ⇒ (y - 9)/5 = sin(t)
so that substituting into the identity above, we get
((x + 7)/5)² + ((y - 9)/5)² = 1
which we can rewrite as
(x + 7)²/25 + (y - 9)²/25 = 1
(x + 7)² + (y - 9)² = 25
and this is the equation of a circle centered at (-7, 9) with radius 5.
Answer: a = 300, b = b = 50.24
Step-by-step explanation:
The given number is not a solution of the equation i.e. the number is an inequality
<h3>How to determine the solution?</h3>
The equation is given as:
3x- 4 = 10
The number is given as:
5
This means that
x = 5
Substitute x = 5 in 3x- 4 = 10
3 * 5- 4 = 10
Evaluate the product
15- 4 = 10
Evaluate the difference
11 = 10
The above equation is not true i.e. the equation is actually an inequality
Hence, the given number is not a solution of the equation i.e. the number is an inequality
