Answer: <em>is it 4, maybe?</em>
First we find the slope between the two given points.
m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7
Now we use the slope-intercept equation of a line.
y = mx + b
We use one point as x and y, and we solve for b.
2 = -7(6) + b
2 = -42 + b
b = 44
The equation is
y = -7x + 44
Answer: f(x) = -7x + 44
So to find the answer you need to use SOHCAHTOA
Sine= Opposite/ Adjacent
Cosine= Adjacent/Hypotenuse
Tan = opposite/adjacent
angle ADC is 60 so to find the length of line ABC we would use the angle and the line DC.
We would use Tan with opposite over adjacent
Tan 60 = opp. / 5 root 3
opp. = 15
so that is the length of the entire thing, all you need to do now is find the length of the single line of BC which we can use the same equation with just Tan 30 now.
Tan 30 = opp. / 5 root 3
opp. = 5
next you need to take the entire ABC length and subtract the length of BC to get AB
15-5 = 10
so the answer would be C
Answer:
See below
Step-by-step explanation:
Part A: The expression would be (4x+5)(3x+10), or, when expanded, 12x^2+55x+50 since the area of a rectangle is length*width
Part B: The degree is 2 because it's classified as a quadratic and trinomial expression
Part C: The closure property of polynomials is that polynomials will be closed under an operation if the operation produces another polynomial. For example, since we had to multiply two binomials in Part A, the exponents of x get combined to make x^2 (because x^1*x^1=x^(1+1)=x^2)
The laws for radicals are derived directly from the laws for exponents by using the definition a m n = a m n . The laws are designed to make simplification much easier. It is important to reduce a radical to its simplest form.
