Complete Question:

The expression 16t² represents the distance in feet an object falls after t seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?

Answer:

H(2) = 842 feet

Step-by-step explanation:

Let the height be H.

Given the following data;

H(t) = 16t²

Height, H = 906 feet

Time, t = 2 seconds

To find the time, t at 2 seconds, we would use the following formula;

H(t) = H - 16t²

H(2) = 906 - 16(2)²

H(2) = 906 - 16*4

H(2) = 906 - 64

H(2) = 842 feet

Therefore, the height in feet of the object 2 seconds after it is dropped is 842.

Answer:

You will need 7 vans and 4 buses

Step-by-step explanation:

7 vans would take care of 35

4 buses would take care of 140 kids

and it uses a total of 11 vehicles

Hope this helps  

Answer:

Vans = 7

Buses = 4

Step-by-step explanation:

x = vans

y = buses

x + y = 11                           (1)

5x + 35y = 175                 Divide this equation by 5

x + 7y = 35                       (2)  

============

                                        Subtract (1) from (2)

x + 7y = 35

x +  y =   11

     6y = 24                      Divide by 6

     6y/6 =24/6

       y = 4

===========

x + y = 11

x + 4 = 11

x = 11 - 4

x = 7

Now Let's check it

x is the number of vans which holds 5 students each

7 * 5 = 35

y is the number of buses which holds 35 students each

4 * 35 =140

Total number of students = 35 + 140 = 175

So it checks.

Answer:

g(f(x)) = x² - 3x + 4

Step-by-step explanation:

Substitute x = f(x) into g(x) , that is

g(x² - 3x + 2)

= x² - 3x + 2 + 2

= x² - 3x + 4

Step-by-step explanation:

a. Belle as she only missed 50 questions where as Aurora missed 78. (500-450) and (650-572)

b. Belle scored 90% (450/500=0.9)

Answer:

a. Belle scored better, by scoring 2% more than Aurora.

b. She scored 90%

Step-by-step explanation:

Make your denominator out of a 100

So you will divide by 6,5

572÷6,5/650÷65

= 88/100

=88%

And divide the other by 5

450÷5/500÷5

=90/100

=90%

Answer:

[tex]c(t) =-18t +212[/tex]

Step-by-step explanation:

Given

[tex](t_1,c_1) = (4,140)[/tex]

[tex](t_2,c_2) = (9,50)[/tex]

Required

Determine the equation

First, we calculate the slope (m)

[tex]m = \frac{c_2 - c_1}{t_2 - t_1}[/tex]

[tex]m = \frac{50 - 140}{9-4}[/tex]

[tex]m = \frac{-90}{5}[/tex]

[tex]m = -18[/tex]

The equation is then calculated as:

[tex]c =m(t - t_1) + c_1[/tex]

[tex]c =-18*(t - 4) + 140[/tex]

[tex]c =-18t +72 + 140[/tex]

[tex]c =-18t +212[/tex]

Hence, the function is:

[tex]c(t) =-18t +212[/tex]

Answer:

y = 6x

Explaination:

slope intercept form is just y=mx+b, and since the slope is 6, you plug 6 into m, and then the y-intercept is 0, so you can drop it out of the equation

Answer: Question 1 is 3/4

Question 2 is the line intersecting at -9 in the y axis and the slope is 4 so the other point would go at (1,-5)

Step-by-step explanation:

Answer:

140.6 feet

Step-by-step explanation:

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.

Step 1

We have to find Angle M

Sum of angles in a triangle = 180°

M + N + O = 180°

M = 180° - ( N + O)

M = 180° - ( 90° + 62°)

M = 28°

Step 2

We find the length of MN

We solve using Sine rule

MN/sin O = NO/sin M

MN/sin 90 = 66/sin 28

Cross Multiply

MN = sin 90 × 66/sin 28

MN = 140.58 feet

Approximately = 140.6 feet
