Answer:
- 3 and x² + 2x - 3
Step-by-step explanation:
(a)
To evaluate g(1) substitute x = 1 into g(x)
g(1) = 1² - 4 = 1 - 4 = - 3
(b)
Substitute x = x + 1 into g(x)
g(x + 1) = (x + 1)² - 4 ← expand parenthesis using FOI
= x² + 2x + 1 - 4 ← collect like terms
= x² + 2x - 3
The equation has exactly 1 real solution.
You can find this by solving it.
8 - 4x = 0 ----> add 4x to both sides
8 = 4x ----> divide both sides by 4
2 = x
You can see there is only 1 and therefore it has one solution.
Answer
Circumference of the track used = 194.68 yards = 194.7 yards to 1 decimal place.
Explanation
The circumference of a circle is given as
Circumference = πD
where
π = pi = 3.14
D = Diameter = 62 yards
Circumference = πD
Circumference = 3.14 × 62 = 194.68 yards = 194.7 yards
Hope this Helps!!!
Answer:
-125/27
Step-by-step explanation:
(-3/5)^-3= 1÷(-3/5)³
=1÷(-3³/5³)
=1÷(-27/125)
=1×(125/-27)
=-125/27
