Given b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C. What is the area of the triangle? Round to the nearest hundredth.

Answers

Answer 1

Answer:

1.73 units

Step-by-step explanation:

The area of a triangle with sides a, b, c and angles A, B, C is given as

Area = 1/2 bc sin A

Given that b=4, c=1, A=120° for a triangle with sides a, b, c and angles A, B, C then the area

= 1/2 * 4 * 1 * sin 120

= 2 sin 120

= 2 * √3/2

= √3

= 1.732

To the nearest hundredth = 1.73

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)

m = [tex]\frac{4-8}{6-2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1

the correct answer is -1

The basketball game lasted 1 hour and 40 minutes. If the game started at 7:30 p.m., what time did it end?

(Answer:_:__)​

Answers

Answer:

9:10pm

Step-by-step explanation:

the game ended at 9:10pm

Answer:

21:10 (24-hour clock) or 9:10 ( 12-hour clock)

Step-by-step explanation:

Two ways it can be solved:

Starting time: 7:30

Game lasted- 1 hour and 40 minutes

Ending time-?

7:30 is converted to 24 hrs timing clock:

hr  I min

   7   :  30 pm

+ 12  :  00

___________

=  19  :  30

Then, hr  I min

        19  :   30

    +   1    :   40

______________

=       20  :   70

    +    1   : - 60

______________

=       21   :  10

So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).

or you can just add up :

  hr  I min

   7  : 30pm

+ 1   :  40

________

=  8 :  70

 + 1  : - 60

_________

=  9  : 10 pm

Write the equation for a radical function that has been flipped left and shifted down 1.

Answers

Answer:

[tex]g(x)=\sqrt{-x}-1[/tex]

Step-by-step explanation:

Let's use the parent function [tex]f(x)=\sqrt{x}[/tex] as an example

Because we are flipping the radical function left, this means [tex]f(x)=\sqrt{-x}[/tex]

Because we are shifting down 1 unit vertically, we have [tex]g(x)=\sqrt{-x}-1[/tex]

Therefore, the final function is [tex]g(x)=\sqrt{-x}-1[/tex]

There were 80 runners to start a race. In the first half of the race, 1/5 of them dropped out. In the second half of the race, 5/8 of the remaining runners dropped out. How many runners finished the race

Answers

Answer:

24

Step-by-step explanation:

Initially, there were 80 runners in the race. After the first half, 1/5 of them dropped out (given). Therefore, 4/5*80=64 runners remain. In the second half, 5/8 of these 64 runners drop out, meaning 3/8*64=24 runners finished the race.

Find the area of each semicircle. Round to the nearest tenth. Use 3.14 for Pi. 1. Diameter = 9.4 mm 2. Radius = 3 1/2 ft 3. Radius =8 in

Answers

Answer:

34.68 mm^2

19.23 ft^2

100.48 in^2

Step-by-step explanation:

Area of a circle = 0.5 x nr^2

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

0.5 x (9.4/2)^2 x 3.14 = 34.68

0.5 x (3.5)^2 x 3.14 = 19.23 ft^2

0.5 x (8)^2 x 3.14 = 100.48 in^2
