tail: 4.5x5/2=11.25, 4.5x3/2=6.75, 11.25+6.75=18
top fin: 3x2.25/2=3.375, 3x0.75/2=1.125, 3.375+1.125=4.5
bottom fin: 1x1/2= 0.5, 1x0.5/2=0.25, 0.5+0.25=0.75
nose: 4.5x2=9
between tail and body: 2.5x2=5
corners on body: 1.5x0.5/2x4=1.5
top and bottom on body: 0.5x5x2=5
body: 1.5x2+5=8, 2x2=4, 4x8=32
total: 18+4.5+0.75+9+5+1.5+5+32=75.75
total area of khianna's fish is 75.75 cm.
hope this helps
Hi
f(x) = g(x) if -x²+3x-2 - ( -x+1) = 0
-x² +3x-2 +x-1 = 0
-x² +4x -3 = 0
To solve, tou have to use the general method of resolution of a quadratic fonction.
To determine if it's has a solution in R, let's calculate Δ
Δ = (4)² - 4 * (1) *(-3)
Δ = 16 +12
Δ= 28
as Δ≥ 0 so the function allow two solution within R
so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2
S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2
S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2
S1 = -2 +√7 S2 = -2 -√7
So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7
If it was a 75% discount, then u r actually paying 25%
so....25% of the original price is $ 11
0.25x = 11
x = 11 / 0.25
x = 44 <=== the original price
Answer:
About 48%
Step-by-step explanation:
divide 30% by 62% and that would be approximately 0.48 or 48%
And what’s the question?????
