So before we can decide which graph it is, we have to find the zeros (x-intercepts) of this graph. We can do this by setting y to 0.
Firstly, factor out 3x on the right side of the equation: 
Next, use the zero product property to solve y = 0:


So we know that the zeros of this equation are (4,0) and (0,0). Looking at the four graphs, the only graph that has a line crossing those 2 points is the first graph. Therefore, the graph of this equation is the first graph.
Answer:
a) 122.5 m ; b) 10 s
Step-by-step explanation:
Just use the given equation and plug in what you know.
a)
d = 4.9t^2
d = 4.9(5^2)
d = 4.9 * 25
d = 122.5 m
b)
d = 4.9t^2
490 = 4.9t^2
100 = t^2
t = 10 s
Answer:
72 units
Step-by-step explanation:
arc length= 48π
Radius: R
48π = 2 * π * R * 120/360
R = 72
<u>Answer:</u>
The net price of the product is $1445.
<u>Solution:</u>
Given, regular price of a product is $1500 and it has a discount at the rate of 3%
We have to find the final price of the product.
We know that, <em>final product of price = regular price – discount price
</em>
Final price of product = 1500 – 3% of 1500
Final price of product 
= 1500 – 3
15 = 1500 – 45
Final price = 1455
Hence, the net price of the product is $1445.
Answer:
-6
Step-by-step explanation:
firstly arrange whole equation,
-2x+7=19
Now, Transpose 7 to RHS (right hand side)
-2x=19-7
-2x=12
Further, seperate coefficient -2 from x
and transpose it to RHS and divide them
x=12/-2
Hence, x= -6
