Lily threw a ball. The balls equation that demonstrated its height and velocity is:

SIZIF [17.4K]

The initial height of the ball is the y-intercept of the function

The initial height she threw the ball from is 35

<h3>How to determine the initial height</h3>

The function is given as:

$h(x) = -16x^2 + 3x +35$

Set x = 0.

So, we have:

$h(0) = -16 * 0^2 + 3*0 +35$

Evaluate the exponent

$h(0) = -16 * 0 + 3 * 0 + 35$

Evaluate the products

$h(0) = 0 + 0 + 35$

Evaluate the sum

$h(0)= 35$

Hence, the initial height she threw the ball from is 35

A box contains 6 wooden, straight sticks of the following lengths (in inches): 2, 3, 5, 7, 11, and 13. Three sticks are drawn at

Vikentia [17]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

given,

straight stick of length = 2, 3, 5, 7, 11, and 13.

For a triangle to form third side of the sum of the two side of the triangle should be greater than third.

so the possibility of triangle formed

5,11,13

7,11,13

3,11,13

7,5,11

5,3,7

ways of drawing 3 wooden sticks

⁶C₃ = $\dfrac{6!}{3!\times 3!}$ = 20

so the probability = $\dfrac{5}{20}$

= $\dfrac{1}{4}$

Three sets have 5, 10, 15 elements, respectively. How many elements can their union and intersection have?

Degger [83]

Answer:

$Union = 15$

Step-by-step explanation:

Given

$n(A) = 5; n(B) = 10; n(C) = 15$

Solving (a): Possible union elements

This is the represented by element with the largest number of the sets

i.e.

$Union = 15$

Solving (b): Possible intersection elements

This is the represented by element with the least number of the sets

i.e.

$Intersection = 5$
