Answer:
The annual rate of interest is 2 %
Step-by-step explanation:
Given as :
The investment amount = $ 3,500
The Interest earn on investment = $ 210
The time period = 3 years
Let The annual interest rate = R
From simple interest method :
Simple Interest =
Or, 210 × 100 = 3500 × R × 3
Or, R =
Or, R = = 2
Hence The annual rate of interest is 2 % Answer
hope this helped :)
Answer:
A. When the preimage of a triangle is a dilation of the image, the triangles are similar.
Step-by-step explanation:
If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.

The question is the thing that needs help. What does that hanging "a leading 2" mean? And rational real coefficients? Obviously if they're rational they're gonna be real, but really.
I would say "a leading 2" means the highest power of x has a coefficient to two, which is none of the above.
The last two are of degree two, which is the lowest degree. They both have integer coefficients, so are necessarily real and rational as well.
Neither has a leading 2 as far as I can tell. The last one is monic (a leading coefficient of 1). I like monic polynomials so I'd pick that one, but that doesn't make it right.
None of the above
Answer:
4x^2 + 9x + 4 = 0
Using the quadratic formula:
x = [-9 +- sqrt(81 - (-64)] / 2 * 4
x = [-9 +- sqrt (145)] / 8
So, the solution is your second answer:
negative 9 plus or minus the square root of 145 divided by 8.
