Answer:
Step-by-step explanation:
we know that
The quadratic function of the figure has a vertex at (2,-5) and the y-intercept is the point (0,3)
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
we have
substitute
with the y-intercept find out the value of a
For x=0,y=3
The equation is
Looking at the graph, the solution is the shaded area below the quadratic equation
so
the value of y must be less than or equal to the quadratic function
Answer:
176 cm
Step-by-step explanation:
45 degrees is what fraction of the circle
45/360 = 1/8
So multiply the arc length by 8 to get the circumference of the entire circle
22* 8 =176 cm
Answer:
Uhh, I think the answer is <em>b</em>?
Step-by-step explanation:
if you look at the area <em>d</em>, it's kind of the same as 18 mm but it isn't. It's a few inches off the same inch as 18 mm, so it MIGHT be <em>b</em>.
(I MIGHT BE WRONG, IF I AM, I AM SORRY. I'M NOT THAT SMART, SO EXPECT SOME WRONG ANSWERS OR NOT.)
Answer:
3x - 3 = 20
Step-by-step explanation:
Times is a word that represents multiplication. A number can be represented by x.
3x - 3 = 20
Solving this:
3x - 3 = 20 1. Add 3 on both sides
3x = 23 2. Divide by 3 on both sides
x = 7 2/3
