Answer:

f(1) = 2

Step-by-step explanation:

To find f(1), substitute x = 1 into f(x), that is

f(1) = 1² + 3(1) - 2 = 1 + 3 - 2 = 2

Use the position equation given below, where s represents the height of the object (in feet),
mariarad [96]

The answers to the questions are

  • The mathematical model is given as s = −16t2 + 1054
  • The height after 4.5 seconds is 730 feet
  • the time it would take to strike the ground is 8.11 seconds.

<h3>How to solve for the position of the object</h3>

The mathematical model of this problem would be written as

s = −16t2 + v0t + s0

s0 = 1054

then we would have

s = −16t2 + 1054

b. after 4.5 seconds the height is going to be

s = −16t2 + 1054

=  −16(4.5)² + 1054

= -16 * 20.25 + 1054

= 730

C. the time that it takes to strike the ground

s = −16t² + 1054

= 16t² = 1054

t² = 1054/16

= 65.88

t = √65.88

t = 8.11

Hence the time it would take to strike the ground is 8.11 seconds.

3) What is the mean value of the data?
soldi70 [24.7K]
The mean - add all the numbers (data) divided by the amount. 4+3+1+1+2+4+1 =16 16/7 = 2.28
The median - the middle number.
The mode - the most common number.

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the mi
g100num [7]
legs of the triangles

Each triangle 30-60-90 is:

         one leg: 15 ft => short diagonal = 2 * 15ft = 30ft

         other leg, x:

         tan(30) = 15 / x => x = 15 ft / tan(30) = 25.98 ft

=> long diagonal = 2 * 25.98ft = 51.96 ft

side of the rhoumbus =  hypotenuse of one triangle

side of the rhombus = √ [ (15)^2 + (25.98)^2 ] = √(900) = 30 ft

Area of the rhombus:

4 * area of one triangle = 4 [base*height/2] = 4*15*25.98/2 = 779.43 ft^2

The shortest distance accross the garden is equal to the side of the rhombus = 30 ft
