X - number of months ( 1, 2 or 3 );
A function is:
f ( x ) = 50 x + 200
A reasonable domain is:
x ∈ { 1, 2, 3 }
The range is:
y ∈{ $250, $300, $350 }
Answer:
third option
Step-by-step explanation:
Answer:
26° 26° 128°
77° 77° 26°
Step-by-step explanation:
So we have two scenarios here.
One of them is if the base angles are 26°.
If that's true, the other angle is 128°
The other scenario is the opposite.
This means the base angles are 77°
Answer:
None of the above, it should be $4760
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 12%/100 = 0.12 per year,
then, solving our equation
I = 3500 × 0.12 × 3 = 1260
I = $ 1,260.00
The simple interest accumulated
on a principal of $ 3,500.00
at a rate of 12% per year
for 3 years is $ 1,260.00
Answer:
Option A
Step-by-step explanation:
Here is how to approach the problem:
We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.
At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.
Now we have two choices left.
For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.
Vertext form is f(x) = a(x-h)^2 + k.
h being the x-coordinate of the vertex and k being the y-coordinate.
We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.
