Answer:
the linear function gives us the points
(0,3)
(4,0)
(8,-3)
find the equation
hm
find slope
(y2-y1)/(x2-x1)
for (0,3) and (4,0)
slope=(0-3)/(4-0)=-3/4
y=-3/4x+b
given
(0,3)
y=-3/4x+3
so sub -3/4x+3 for y in other equation
(-3/4x+3)^2+x^2=4
expand
9/2x^2-9/2x+9+x^2=4
11/2x^2-9/2x+9=4
times 2 both sides
11x^2-9x+18=8
minus 8 both sides
11x^2-9x+10=0
factor
or use quadratic formula
for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
2a
−b+/−
b
2
−4ac
11x^2-9x+10=0
x=\frac{-(-9)+/- \sqrt{(-9)^2-4(11)(10)} }{2(11)}
2(11)
−(−9)+/−
(−9)
2
−4(11)(10)
x=\frac{9+/- \sqrt{81-440} }{22}
22
9+/−
81−440
x=\frac{9+/- \sqrt{-359} }{22}
22
9+/−
−359
we see we have no real roots
there are no intersection points

Answer:
Step-by-step explanation:
Here we have the length of the hypotenuse (16) and that of the vertical leg (11). The cosine function inputs this data:
adjacent side 11
sin x = ----------------------- = ---------------- = 0.6875
hypotenuse 16
We find x using the arccos function: arccos 0.6875 = 0.81 radians or
46.57 degrees
Answer:
27x^5 + 30x^4
Step-by-step explanation:
Multiply 3x^3 out of (9x^2 + 10x)
Step 1. Multiply 3x^3 x 9x^2
Answer: 27x^5
Step 2. Multiply 3x^3 x 10x
Answer: 30x^4
“Add these two products together”
27x^5 + 30x^4
Hope this helps!
