Step-by-step explanation:
Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=
base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
The functions are both increasing
the function for plan II has a greater unit rate
The function for plan I has a greater y intercept
