Answer:

(one thing to notice, the units of the 16 in the height equation should be ft/s^2, because this is an acceleration)

We know that:

v is the initial vertical velocity, and we know that it is 10ft/s

then:

v = 10ft/s.

s is the initial position, and we know that he starts on a platform 25ft above the pool, then if we define the pool as the 0 in the vertical axis, we have:

s = 25ft

Now we can write the height as:

h(t) = (-16ft/s^2)*t^2 + (10ft/s)*t + 25ft.

Now with this equation, we can find the time it takes for the diver to hit the pool.

Remember that we defined the pool as the 0 in the vertical axis, then when h(t) = 0ft the diver will enter in the pool.

With that, we can find the value of t = time, that it takes for the diver to enter the pool.

h(t) = 0 ft = (-16ft/s^2)*t^2 + (10ft/s)*t + 25ft.

Now we can solve this with the Bhaskara equation:

[tex]t = \frac{-10m/s +. \sqrt{(10m/s)^2 - 4*(25ft)*(-16ft/s^2)} }{-16ft/s^2*2} = \frac{-10ft/s +- 41.23ft/s}{-32ft/s^2}[/tex]

We will have two solutions:

t = ((-10 + 41.23)/-32) s = -0.96s

t = (-10 - 41.23)/-32) s = 1.6 s

The negative has no physical sense, so we can discard that option.

This means that the only correct option is 1.6 seconds, then the time that it takes for the diver to enter the pool after he jumps is 1.6 seconds.

Answer:

-2

Step-by-step explanation:

Opening bracket,

6x+15 +4=7

6x=7-19    (I took 15 and 4 to other side and thus they became negative)          

x=-12/6

x=-2

Pls mark me brainliest

Answer:

The answer is x = -2

Step-by-step explanation:

FOIL

3*2x + 3*5 + 4 = 7

6x + 15 + 4 = 7

6x + 19 = 7

Subtract 19 from both sides.

6x =  -12

Divide both by 6.

x = -2

Answer:

it is 32

Step-by-step explanation:

15 divided by 3 is 5 and if you are trying to find the second triangles sides you would subtract 5 from 12 to get 5 and 2. then you would multiply all the sides by 3 and add them together to get 32.

Answer:

a = 12

Step-by-step explanation:

Given that a is inversely proportional to b then the equation relating them is

a = [tex]\frac{k}{b}[/tex] ← k is the comstant of proportion

To find k use the condition when a = 4, b = 36, then

4 = [tex]\frac{k}{36}[/tex] ( multiply both sides by 36 )

144 = k

a = [tex]\frac{144}{b}[/tex] ← equation of proportion

When b = a , then

a = [tex]\frac{144}{a}[/tex] ( multiply both sides by a )

a² = 144 ( take square root of both sides )

a = ± [tex]\sqrt{144}[/tex] = ± 12

However a is a positive number, thus a = 12

Answer:

8208 Rs

Step-by-step explanation:

Rs: 10260

Profit 20%

10260 * 0.20 * 100% = 2052 Rs

10260 Rs - 2052 Rs = cost of product to be produced

CP: Rs 10260

Profit: 20%

Solution: 20% off 10260 is equal to (20 x 20) / 100 = 2052. So if you buy an item at $10260 with 20% discounts, you will pay $8208 and get 2052 cashback rewards

Answer:

x = 9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

44 = 2(3x − 5)

44 = (2)(3x) + (2)(−5) (Distribute)

44 = 6x + −10

44 = 6x − 10

Step 2: Flip the equation.

6x − 10 = 44

Step 3: Add 10 to both sides.

6x − 10 + 10 = 44 + 10

6x = 54

Step 4: Divide both sides by 6.

[tex]\frac{6x}{6} = \frac{54}{6}[/tex]

x = 9

Answer:

Answer: 2/3

Step-by-step explanation:

6 and 9 are divisible by 3 so if you divide the numerator and denominator by 3 you obtain the equivalent fraction 2/3.

You can also multiply the numerator and denominator by the same amount to obtain an equivalent fraction.

Answer:

1/5 pint

Step-by-step explanation:

given:

Amount of Glue needed = 9/10 pints

Amount of Glue available = 7/10 pints

Amount of extra glue needed = Amount of glue needed - Amount of Glue Available

= 9/10 - 7/10

= (9-7)/10

= 2/10   (simplify by dividing both numerator and denominator by 2)

= 1/5 pint

Answer/Step-by-step explanation:

If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.

Total income estimated in a month:

Sales: $950 per week = 950*4weeks = $3,800 per month

Services: $2,875 per month

Total estimated income per month = $(3,800 + 2,875) = $6,675

Total expenses estimated in a month:

Rent: $4,500 per month

Travel: $7.5 per day = 7.5*7days = $52.5 per week.

Assuming there are 4 weeks in a month, expenses for travel in a month will be:

$52.5*4 = $210

Merchandise: $1,650 per month

Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360

Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

Answer:

CE=108

Step-by-step explanation:

*I don't have my phone with me so I can't add a picture of what I drew*

First, draw a line. On one end, write C. On the other end, write E. In the middle of them, write D. The question states that CE=6x, so on the bottom of the line, write 6x. On top on the first half write 4x+8 (between C and D). On the other half between D and E write 28.

According the the information we have been given and the diagram we made, CD+DE=CE. Hence, (4x+8)+28=6x

(4x+8)+28=6x (subtract four from both sides)

8+28=6x-4x (combine like terms)

36=2x (divide two from both sides)

x=18

Now, substitute 18 for x in 6x (CE=6x)

CE=6(18)

CE=108

Answer:

[tex]x=\frac{1}{6}[/tex] or [tex]x=1.6667[/tex]

Step-by-step explanation:

All you have to do is divide both sides by 3. When dividing decimals it's sometimes easier to change it to a fractions like so: [tex]x=\frac{1}{2} /\frac{3}{1}[/tex] to divide fractions you multiply the reciprocal like this: [tex]x=\frac{1}{2} * \frac{1}{3}[/tex] to get [tex]x=\frac{1}{6}[/tex]

Answer:

The correct answer is D) sin(2x) = sin(x)cos(x)+sin(x)cos(x)

Step-by-step explanation:

Right answer on Edge

The step 2 will be;

⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The steps are;

Step 1; sin (2x) = sin (x + x)

Step 3; sin (2x) = 2 sin (x) cos (x)

Now,

Since, The steps of the solution are;

Step 1; sin (2x) = sin (x + x)

Step 3; sin (2x) = 2 sin (x) cos (x)

Hence, We get;

All the steps as;

⇒ sin (2x) = sin (x + x)

⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)

⇒ sin (2x) = 2 sin (x) cos (x)

Thus, The expression for step 2;

⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)
