Step-by-step explanation:
Answer:
1.03x
Step-by-step explanation:
1 year b would be the inital investment added with interest
i believe this is the equation
b = x + r(x)= (1 + r)x
and since it says 3% each year we know its 0.03 (r)
and when you solve it out you get that answer
Convert to vertex form
or easier
for y=ax²+bx+c
the x value of the vertex is

and the y value is found by subsituting the x value in for x
so
y=1x²+4x+11
a=1
b=4
the x value of the vertex is

the y value is found by subsituting -2 for x
y=(-2)²+4(-2)+11
y=4-8+11
y=7
the vertex is (-2,7)
Answer:
27.7 cm
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side in a right triangle to the hypotenuse. Here, that means ...
cos(30°) = y/(32 cm)
y = cos(30°)·(32 cm) ≈ 0.866·(32 cm)
y ≈ 27.7 cm
