This is obviously a decreasing sequence. Thus, the common ratio is the fraction 1/4, not the integer 4. Eliminate C and D. Next, at n=1, the value of the 1st term is 16, which is actually 16(1/4)^(1-1) = 16(1) = 16. Thus, B is correct.
Answer:
Option (D) is correct
Step-by-step explanation:
A circle has (a , b ) are the coordinates of the centre and .
Given.
A circle is centered at (2,-5) and has radius 3
Let and and
The standard form of the circle is.
------(1)
Put a, b and r value in equation 1.
So. the standard form of equation is.
Answer:
- Trapezoid with the area 16.5 unit²
Step-by-step explanation:
Plotted the given points to find out the figure is trapezoid.
<u>Area formula for trapezoid:</u>
<u>The length of the bases:</u>
- b₁ = DE = 3 - (-1) = 4
- b₂ = FG = 4 - (-3) = 7
<u>h is the horizontal distance between the bases:</u>
<u>The area is:</u>
- A = 1/2(4 + 7)(3) = 16.5 unit²
Not equivalent to any of the given expressions.
Step-by-step explanation:
Hence, is not equivalent to any of the given expressions.
Answer:
C
Step-by-step explanation:
The best way to solve this is to transfer -217 to the other side. So add 217 to both sides
0 ≤ 7 + 217 - 28v Combine
0 ≤ 224 - 28v Now add 28v to both sides
28v ≤ 224 Divide by 28
28v/28≤224/28
v ≤ 8
You should have 2 questions on your mind.
- Why go to all the trouble of putting things on the opposite sides?
- What is the answer
1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.
2. The is v is less than or equal to 8. That's C
