Answer:

$\boxed{\bold{66k+9}}$

Explanation:

Expand $\bold{5\left(10k+1\right): \ 50k+5}$

= $\bold{50k+5+2\left(2+8k\right)}$

Expand $\bold{2\left(2+8k\right): \ 4+16k}$

= $\bold{50k+5+4+16k}$

Simplify $\bold{50k+5+4+16k: \ 66k+9}$

= $\bold{66k+9}$

At a high school, students can choose between three art electives, four history electives, and five computer electives. Each stu

V125BC [204]

Answer:

$\frac{^3C_1\times ^4C_1}{^{12}C_2}$

Step-by-step explanation:

Given,

Art electives = 3,

History electives = 4,

Computer electives = 5,

Total number of electives = 3 + 4 + 5 = 12,

Since, if a student chooses an art elective and a history elective,

So, the total combination of choosing an art elective and a history elective = $^3C_1\times ^4C_1$

Also, the total combination of choosing any 2 subjects out of 12 subjects = $^{12}C_2$

Hence, the probability that a student chooses an art elective and a history elective = $\frac{\text{Total combination of choosing an art elective and a history}}{\text{ Total combination of choosing any 2 subjects}}$

$=\frac{^3C_1\times ^4C_1}{^{12}C_2}$

Which is the required expression.

Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.

Reika [66]

Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
