1. Timika is a counselor at a summer camp for young children. She wants to take 20 campers on a hike and wants to

OLga [1]

Answer: N = 20C2 = 190

Therefore, Timika has 190 ways of choosing the pairs of children to lead the way

Step-by-step explanation:

Given;

Total number of children = 20

Number of children to lead the way = 2

Since all the children have equal possibilities of being selected to lead the way, and for the order is not important.

Then the number of ways to select two leaders from 20 children will be given by;

N = 20C2 = 20!/2!(20-2)! = 20!/2!18!

N = 20 × 19/2

N = 190

Therefore, Timika has 190 ways of choosing the pairs of children to lead the way

Use the discriminant to determine which graph could represent the equation. y=x^2+4x+5

lidiya [134]

ANSWER

See attachment.

EXPLANATION

The given function is

$y = {x}^{2} + 4x + 5$

When we compare this function to

$y = a{x}^{2} + bx + c$

We have a=1, b=4 and c=5

We put this inside the formula for the discriminant, which is

$D = {b}^{2} - 4ac$

$D = {4}^{2} - 4(1)(5)$

$D = 16 - 20 = - 4$

Since the discriminant is negative, the function has no x-intercepts.

The graph of this function is the one hanging in the air above the x-axis and opens upwards.
