How do I do numbers 12 to 14?

NARA [144]

Answer:

12. 1 second, 35 ft; 2 seconds, 32 ft

13. (t, y) = (1.4 seconds, 37.6 feet)

14. 37.6 ft; the vertex is the highest point

Step-by-step explanation:

12. You have properly answered question 12.

After 1 second, the height is 35 feet; after 2 seconds, it is 32 feet.

13. My method of choice is to plot the graph on a graphing calculator and let it show me the coordinates of the vertex when I highlight that point. (See attached.) The vertex is ...

(t, y) = (1.4, 37.6)

14. The graph is a graph of height when the object is launched with a vertical velocity of 45 ft/s. So, the maximum of the graph will correspond to the maximum height of the object. The vertex is that maximum point, and its y-coordinate is that maximum height.

The maximum height is 37.6 feet.

Suppose you and a friend each choose at random an integer between 1 and 8, inclusive. For example, some possibilities are (3,7),

Bezzdna [24]

Answer and explanation:

Given : Suppose you and a friend each choose at random an integer between 1 and 8, inclusive.

The sample space is

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (1,7) (1,8)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (2,7) (2,8)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (3,7) (3,8)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (4,7) (4,8)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (5,7) (5,8)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6) (6,7) (6,8)

(7,1) (7,2) (7,3) (7,4) (7,5) (7,6) (7,7) (7,8)

(8,1) (8,2) (8,3) (8,4) (8,5) (8,6) (8,7) (8,8)

Total number of outcome = 64

To find : The following probabilities ?

Solution :

The probability is given by,

$\text{Probability}=\frac{\text{Favorable outcome }}{\text{Total outcome}}$

a) p(you pick 5 and your friend picks 8)

The favorable outcome is (5,8)= 1

$\text{Probability}=\frac{1}{64}$

b) p(sum of the two numbers picked is < 4)

The favorable outcome is (1,1), (1,2), (2,1)= 3

$\text{Probability}=\frac{3}{64}$

c) p(both numbers match)

The favorable outcome is (1,1), (2,2), (3,3), (4,4), (5,5), (6,6), (7,7), (8,8) = 8

$\text{Probability}=\frac{8}{64}$

$\text{Probability}=\frac{1}{8}$

During one term Rachel took 2 mathematics test her mean score was 75 she scored 12 points more on the first test then the second

MaRussiya [10]

Answer: she scored 69 points on the second test.

Step-by-step explanation:

Let x represent the number of points that she scored in the first test.

Let y represent the number of points that she scored in the second test.

If her mean score was 75, it means that

(x + y)/2 = 75

x + y = 75 × 2

x + y = 150- - - - - - - - - 1

If she scored 12 points more on the first test than the second test, it means that

x = y + 12

Substituting x = y + 12 into equation 1, it becomes

y + 12 + y = 150

2y + 12 = 150

2y = 150 - 12

2y = 138

y = 138/2

y = 69

Can some explain steps

Mashutka [201]

Answer:

r = 3.

Step-by-step explanation:

16 = 10 + √(3r + 27)

√(3r + 27) = 6

Square both sides:

3r + 27 = 36

3r = 36 - 27 = 9

r = 3.

Check the result:

Left side of the equation = 16

Right side = 10 + √(9 + 27)

= 10 + √36 = 16
