Answer:
1/4 ft
Step-by-step explanation:
Area is equal to length times width
A = lw
1/2 = 2*w
Divide each side by 2
1/2 ÷2 = 2w/2
1/4 = w
We factor the equation to get:
-(x-25)^2+361
In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.
B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.
Answer:
C. 0.60
Step-by-step explanation:
We need to find out a couple things first:
- How many students are from Westville?
- How many students did not attend the game that are from Westville?
We need to find specifically Westville, because we don't want to accidentally pick someone from North Beach who attended.
So let's look:
- Total from Westville: 150
- Total who did not attend from Westville: 90
Now in order to find a probability, we need to divide the smaller number from the biggest number. Let's do that:
90/150 = 0.6
And for this question, we specifically have to round to two decimal places. In order to do this, we just write the extra 0 at the end:
0.6 = 0.60
Look at that, 0.60 is one of our answers! :D
Answer:
3:2 i believe
Step-by-step explanation:
9:6
divide by 3
3:2
Answer:
A
Step-by-step explanation:
given
16x² + 4 = 0 ( subtract 4 from both sides )
16x² = - 4 ( divide both sides by 16 )
x² = 
= - 
[ take the square root of both sides ]
x = ± 
= ± 
i ( 
= i )
