So what we want to know is how long is the car that is 6% shorter then the other car. We can look at it this way: the shorter car is 94% the lenght of the longer car. Lets call the length of the shorter car x, then we have the equation: 94% * 3.9m=x. Or, (94/100)*3.9=x. Now we solve for x and get: x= 3.666m. So the shorter car is 3.666 m long.
Answer:
X intercepts are points where a function intersects or cuts through the x axis where y=0.
Step-by-step explanation:
In the function given which is f(x) =x^2 +4x + 3 we see that this is a parabola of which when the graph is drawn it has a U shape so when finding x intercepts of this function it is those points on the function where the graph cuts the x axis and at those two points f(x)= 0, so here Mathieu had made a mistake of factorizing and equating the x intercepts for this function.
For finding the X intercepts let f(x) = 0
therefore 0= x^2 + 4x + 3 now we solve for x
0= (x+1)(x+3)
(x+1)= 0 or (x+3)=0
therefore x=-1 or x=-3
now if you substitute these values onto the function they give f(x)= 0,
f(-1) = (-1)^2 + 4(-1) + 3 = 0
f(-3) = (-3)^2 + $(-3) + 3 =0
now let us look at Mathieus answer which is x+1 = x+3 yes these x values do give the same y value but they are not equal because if you can actually solve this further you would not get a defined answer. Both these are factors of the function but are not actually equal as the function would not be able to be drawn if this was the case.
Answer:
Exact Form: x = 5 + sqaureroot 11/2
Decimal Form: x = 4.15
It would be C.
For example, say 1 person comes. This would be x=1. Plugging this in gives you,
y=0.5 + 1.3
This shows that C is true since x is always going to be multiplied by 0.5.
1.3 would be the base amount of time it takes to arrange since if it the y-intercept.
Volume=heiht times area of base
base=circle
area of circle=pir^2
volume=hpir^2
diameter=2r
diametr/2=r
diameter=8.5
find radius
r=8.5/2
r=4.25
h=11.5
subsitute
v=11.5 times pi times 4.25^2
v=11.5 times pi times 18.0625
v=pi times 207.71875
round to hundreth
v=207.72pi in^3
volue=207.72pi in^3
if you want to aprox pi to 3.14 and solve for that then
v=207.72 times 3.14
v=652.24
so
v=207.72pi in^3 or
v=652.24 in^3 aprox (both aer eequatal)
