Answer:

14.2°

Step-by-step explanation:

We solve this using the Cosine rule formula

​From the question we have

Side a = 5

Side b = 11

Side c = ?

We are given Angle C = 120°

Hence,

c² = a² + b²− 2ab cos(C)

Hence,

c² = 5² + 11² - 2(5 × 11) × cos (120°)

c =√[ 5² + 11² - 110 × cos (120°)]

c = 14.18 °

Approximately to the nearest tenth

c = 14.2°

Answer:

10). Proportional

11). Not proportional

Step-by-step explanation:

10) Let the relation between time (t) and heart beats (b) is proportional,

    h ∝ t

    h = kt

    here, k = proportionality constant

    Since, the graph of the equation is passing through a point a (4, 6),

    6 = 4k

    k = [tex]\frac{6}{4}[/tex]

    k = 1.5

    So the equation will be,

    h = 1.5t

   Since, all the points (6, 9), (10, 15)and (12, 18) follow the same relation represented by the equation, relationship is proportional.

11). Let the relationship shown by the table is proportional,

   y ∝ x

   y = kx [Here, k = proportionality constant]

   k = [tex]\frac{y}{x}[/tex]

   This constant should be same for all points given in the table.

   For (4, 25),

   k = [tex]\frac{25}{4}[/tex]

   For (0, 5),

   k = [tex]\frac{5}{0}[/tex]

   This shows 'k' is not same for all points.

   Therefore, relationship between x and y is not proportional.

Answer:

time = 1secs

Max height = 25metres

Step-by-step explanation:

Let the equation that models the height of the ball be expressed as;

h(t) = −16t^2 + 32t + 9

t is the time in seconds

The velocity of the ball at its maximum height is zero i.e dh/dt = 0

dh/dt = -32t + 32

0 = -32t + 32

32t = 32

t = 32/32

t = 1 seconds

The ball will reach its maximum height after 1 seconds.

Get the maximum height reached. Substitute t = 1 into the modeled function;

h(t) = −16t^2 + 32t + 9

h(1) = −16(1)^2 + 32(1) + 9

h(1) = −16 + 32 + 9  

h(1)= 16+9

h(1) = 25

Hence the maximum height reached is 25metres

The budget is $100, and you have already bought 15 podcasts from spotify, $5 each. I came up with this equation:

[tex]15 * 5 = 75[/tex]

You have already spent $75 from the budget so you have to subtract them:

[tex]100 - 75 = 25[/tex]

You can only spend $25 from the budget, and since each Itunes cost $2, i came up with this equation:

[tex]25/2= 12.5[/tex]

You can buy 12 podcasts from Itunes, and be left with .50 cents

Thank you! btw can you give me brainly :3

Answer:

a) [tex]\boxed{\boxed{\sf p = 18 }}[/tex]

b) [tex]\boxed{\boxed{\sf t = 3 }}[/tex]

c) [tex]\boxed{\boxed{\sf p = 6 / by /5 }}[/tex]

Explanation -

a) 2/3 p + 10 = r

Value of r = 22 (given)

2/3 p + 10 = 22

2/3 p = 22- 10

2/3 p = 12

p = 12 × 3 /2

p = 6 × 3

p=18

b) (-17) + 5k = t

value of k = 4 (given)

(-17) +5 (4) = t

(-17) + 20 = t

3 = t

c) 0 = 5p - 3b

b= 2 (given)

0 = 5p - 3(2)

0 = 5p - 6

6 = 5p

6/5 = p

Answer:

isosceles

Step-by-step explanation:

Step-by-step explanation:

Given A( 1 , -2)=( x1, y1)

B( x2 , y2)

Mid point of AB, M ( -2 , 1)

Now we have the formula for the mid point that is

Mid point of AB = [ (x1 + x2)/ 2 , ( y1 + y2) /2]

Or, ( -2 , 1 ) = [ ( 1 + x2) / 2 , ( -2 + y2) / 2]

Now equating with the corresponding elements we get,

-2 = ( 1 + x2) / 2

-4 = 1 + x2

x2 = -4 - 1

x2 = -5

Also

1 =( -2 + y2) / 2

2 = -2 + y2

y2 = 2+2

y2 = 4

Therefore the coordinates of B are ( -5 , 4)

Answer:

Washing Machine 1 $480 × .5030 = $241.44

$480 - $241 = $238.56

So Wahsing Machine #1 was $480 and was marked down by .5030% which takes off $241.44 which brings us to the total to $238.56

Washington Machine #2

$480 × .30% = $144 × .20% = $28.80

So Washing Machine 2 was $480 and was marked down by .30% which took off $144 and was marked down by an additional .20% which took off an additional $28.80 which brings the Grand Total of $307.20.

Joanne should buy the first Washing Machine rather than the second Washing Machine because the first Washing Machine is $68.64 cheaper than the second Washing Machine.
