Do 4.25x4 and if it equals 17 he is correct, otherwise he is incorrect
7 2 18
--- + ----- = ------ or as a decimal: 0.72
10 100 25
:))
<span>f(x)= 2x²-4x
</span><span>g(x)= 5-2x
</span> f(x)-g(x) = 2x²-4x - ( 5-2x) = 2x² - 4x-5+2x= 2x² -2x-5
f(x)-g(x) = 2x² -2x-5
f(5)-g(5) = 2*5² -2*5-5=50-10-5 =35
f(5)-g(5) = 35
This is my go at the problem.
Let x be the original price.
72/100=6/100 of x.
so,
x=72/100 ÷ 6/100= $12.00
The answer is $12.00
Hope this helps!
Answer:
d. parabola, 0°
Step-by-step explanation:
y² + 8x - 0
y² = -8x
Where x = cos t , y = sin t
Sin² t = -8 Cos t
1 - Cos² t = -8 Cos t
- Cos² t + 8 Cos t + 1 = 0
t = 2лπ ± (3 + √10) , л∈Z
Angle of rotation
