Answer:
7. Height = 21 in
8. Height = 13 cm or 130 mm
Step-by-step explanation:
7.
½ × 5 × height = 52.5
height = 21 in
8.
23 mm ÷ 10 = 2.3 cm
½ × 2.3 × height = 14.95
height = 13
Answer: f(x)=125g+50
Explanation: He is charging $125 for each gold piece so you would multiply “g” and 125.
You would add 50 as a one time fee so you add 50.
Answer:
(- 3, - 13 ) and (8, 1 )
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
Both equations are in vertex form
(8)
y = 5(x + 3)² - 13
with vertex = (h, k) = (- 3, - 13 )
(9)
y = (x - 8)² + 1
with vertex = (h, k) = (8, 1 )
