An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?

Answers

Step-by-step explanation:

h= 20t - 4.9t^2

when h=19.6m

19.6=20t - 4.9t^2

4.9t^2 -20t+19.6=0

solving quadratically

t= 1.64 seconds or t= 2.45 seconds

Find the value of cos 45° + sin 30° Solution: Given, cos 45° + sin 30° cos 45° + sin

30° = 1/√2 + ½ = (√2+1)/2 Question 2: Evaluate: 2 sin 60° – 4 cos 45° Solution: Given, 2 sin 60° – 4 cos 45° Since, sin 60° = √3/2 and cos 45° = 1/√2

Therefore, ⇒ 2 (√3/2) – 4 (1/√2) ⇒ √3 – 2√2 Question 3: Find Cos 45 + Cos 90. Solution: Cos 45° = 1/√2 Cos 90° = 0 Therefore, Cos 45° + cos 90° = 1/√2

For any linear function f(x) = mx + b, when does kf(x) = f(kx)?

Answers

Only when b = 0 or k = 1.

If f(x) = mx + b, then

f (kx) = m (kx) + b = mkx + b

while

k f(x) = k (mx + b) = kmx + kb

The two expression are identical only if

kb = b   ===>   kb - b = 0   ===>   b (k - 1) = 0   ===>   b = 0 or k = 1

The new dolphin tank at the city aquarium is in the shape of a rectangular prism. It is long by wide by deep. To make the tank livable for the dolphins, the aquarium workers treat the water using bags of salt. The amount of water a bag of salt can treat is known in cubic feet.
(a) Find the volume of water in the tank in cubic feet.

(b) To make the tank livable for the dolphins, a bag of salt must be added for each 19.4ft$ of water. The aquarium doesn't have any salt on hand and the salt can only be purchased in whole bags. How many bags of salt must be purchased to treat the water?
(c) If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new dolphin tank?
answer quickly

Answers

The volume of water in the tank is 35,100 cubic feet.

What is the volume of the rectangular prism?

Volume = length × width × height

We have the following parameters based on the information provided;

Length = 20 meters

Width = 13 meters

Height = 5 meters

Substitute the values into the formula to get

Volume = 20 × 13 × 5

Volume = 1300 cubic meters

Convert the cubic yard into cubic feet

1 cubic yard = 27 cubic foot

⇒ 1300 yards = x

⇒ x = 27 × 1300

⇒ x = 35,100 cubic feet

Therefore, the amount of water a bag of salt can treat is 35,100 cubic feet

9(x/3+1)>6.
A.x>-5
B.x>2

D.x>-1

Answers

Answer:

D.

Step-by-step explanation:

We are given

9(x/3 + 1) >= 6

Divide 9 on both sides

x/3 + 1 >= 2/3

Subtract 1 on both sides

x/3 >= -1/3

Multiply 3 on both sides

x >= -1

plz helppppppppppppppppppppppppppppppppppp

Answers

Hey there!

10x ÷ 8 = 18

MULTIPLY 8 to BOTH SIDES

10x ÷ 8 * 8 = 18 * 8

SIMPLIFY IT

NEW EQUATION: 10x = 144

DIVIDE 10 to BOTH SIDES

10x/10 = 144/10

CANCEL out: 10/10 because it gives you 1

KEEP: 144/10 because it helps simplify for the x-value

x = 144/10

x = 144 ÷ 2/10 ÷ 2

x = 72/5

Therefore, your answer is: x = 72/5

find the intersection of the two lines by solving the system of equations please help I will give brainliest

Answers

Answer:

(-3, -5)

Step-by-step explanation:

We can add the two equations together so the x's cancel out:

x + y = -8

-x + y = -2

2y = -10

y = -5

We can substitute y in to get x:

x - 5 = -8

x = -3

This means the intersection is (-3, -5).

A package of 6 pairs of insulated gloves costs $38.94. What is the unit price of the pairs of gloves? The unit price is $ per pair of gloves.​

Answers

Answer:

6.49

Step-by-step explanation:

6 pairs of insulated gloves cost $38.94

That means 6 x (price of one glove) = 38.94

Let's say the price of on glove = x

The equation is :

6x = 38.94

x = 38.94 ÷ 6                                   (divide all sides by 6)  

x = 6 + (2.94 ÷ 6)                             (Splitting numbers to multiples of 6)

x = 6 + 0.4 + ( 0.54 ÷ 6)                  (Splitting numbers to multiples of 6)

x = 6 + 0.4 + 0.09                           (Adding all sums)

x = 6.49

Each pair of gloves cost 6.49
