Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
Answer:
A
Step-by-step explanation:
Division by zero is undefined, thus
has a quotient undefined because the denominator is zero
Answer:
Step-by-step Explanation:
Given:
∆UVW,
m < U = 33°
m < V = 113°
VW = u = 29 m
Required:
Area of ∆UVW
Solution:
Find side length UV using Law of Sines
U = 33°
u = VW = 29 m
W = 180 - (33+113) = 34°
w = UV = ?
Cross multiply
Divide both sides by sin(33) to make w the subject of formula
(rounded to nearest whole number)
Find the area of ∆UVW using the formula,
(to nearest tenth).
