Step-by-step explanation:

Boys to girls

2 : 3

Units of girls = 3

3 units = 18

In a certain Algebra 2 class of 26 students, 5 of them play basketball and 12 of them play baseball. There are 12 students who p

loris [4]

Answer: $\dfrac{7}{13}$

Step-by-step explanation:

There are only two games basketball and baseball.

Any student who plays could play basketball or baseball.

Given that there are $26$ students in total.

Given that there are $12$ students who don't play any game at all.

So,there are $26-12=14$ students who play play some baseball or basketball.

$Probability=\frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$

The required probability is $\frac{14}{26}=\frac{7}{13}$

What is the vertex of the quadratic function f(x)=(x-8)(x-2)

Mrac [35]

So firstly, foil (x-8)(x-2): $f(x)=x^2-2x-8x+16\\ f(x)=x^2-10x+16$

Next, remember that the vertex lies on the axis of symmetry, and the equation to find the axis of symmetry is $x=\frac{-b}{2a}$ (a = x^2 coefficient, b = x coefficient). Solve for the axis of symmetry as such:

$x=\frac{10}{2*1}=\frac{10}{2}=5$

So now that we know that the axis of symmetry is x = 5, we also know that's the vertex's x-coordinate (since the vertex falls on the axis of symmetry). Now plug in 5 for x in the original equation to solve for f(5):

$f(5)=5^2-10(5)+16\\ f(5)=25-50+16\\ f(5)=-9$

So putting it together, the vertex of this equation is (5,-9).

Can someone explain to me how this problem is solved? Thanks.

If the function is h(t)=-16t^2+24, where h(t) is the height of the coconut in feet, then we can figure out the initial height (in feet) based on something called initial conditions. Initially, time is 0 seconds. Plugging that number into the equation results in:
h(0)=-16(0)^2+24 = 24 feet. Therefore, the initial height of the coconut is 24 feet
