Answer:
x = 60°
Step-by-step explanation:
The measure of x is one- half the difference of the measures of the intercepted arcs.
The minor arc = 120°, hence
The major arc = 360° - 120° - 240°, so
x = 0.5(240 - 120) = 0.5 × 120° = 60°
Answer:
a) The minimum y-value of f(x) is -3
d) The minimum y-value of g(x) is -3
Step-by-step explanation:
Given in the question that,
f(x) = 3
-3
g(x) = 7x² - 3
<h3>A)</h3>
At large negative exponents, the value approaches to zero
y = 
y = 
y = 
<h3>B)</h3>
Minimum y-value of g(x) will be when x = 0
y = 7x² - 3
y = 7(0) - 3
y = -3
Answer:
y = (x + 8)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term )² to x² + 16x
y = x² + 2(8)x + 64 - 64 + 70
= (x + 8)² + 6 ← in vertex form
Answer: 24 sq. ft
Step-by-step explanation: 20 x 36 - (36 - 20 / 2 ) x (20 - 14 )= 24 sq. ft
