The answer to your question is 6.54
X% of y
x%=x/100
'of' means multiply
x% of y=x/100 times y so
48% of 8=48/100 times 8=384/100=3.84
3% of 119=3/100 times 119=357/100=3.57
26% of 280=26/100 times 280=7280/100=72.8
1. To find the vertex of a parabolla whose equation is written in the standard form, you must apply the following proccedure:
2. You have:
y=-0.18x²+4.4x-12
a=-0.18
b=4.4
3. You must apply the following formula:
<span>
x=-b/2a
x=-4.4/2(-0.18)
x=-4.4/-0.36
x=12.22
4. When you susbtitute x=12.22 into the equation </span>y=-0.18x²+4.4x-12, you obtain:
y=-0.18x²+4.4x-12
y=-0.18(12.22)²<span>+4.4(12.22)-12
</span> y=14.88 feet
5. The answer is: The maximum height of the tunnel is <span>14.88 feet</span>
Answer:
X1 = 3
X2 = -4
Step-by-step explanation:
Slope/m=3-(-7)/-3-2=10/-5=-2
slope/m=-2
y=-2x+b
b= 3=-2*-3+b
b=-3
