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.

Number equivalent to 15/12 is 1.25 .

Given,

15 divided 12

Using division property,

The rules for division are:

(1) positive × or ÷ positive = positive

(2) positive × or ÷ negative = negative

(3) negative × or ÷ negative = positive

Rule for long division method,

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

Therefore,

divide, multiply, subtract, bring down and repeat or find the remainder.

Here the required value is of :

15/12

=5/4

= 1.25

Hence the answer is 1.25

Answer:

-23

Step-by-step explanation:

Substitute the value of the variable into the expression and simplify.

Answer:

Area of rectangular field = 12750 square yards

Width = 150 feet

<< Find the length of the field in yards. >>

Your conversion factor: 3 feet = 1 yard

Width = 150 feet = 150/3 = 50 yards

Therefore,

Area = 12750 = L(50)

where

L = length of field = 12750/50

L = 255 yards

<< What is the length of the field in feet? >>

L = 255 yards * 3 feet/yard

L = 765 feet

< .What is the area of the field in square feet? >>

Since there are 3 feet in 1 yard, then there are 9 sq ft in 1 sq yard. Therefore,12750 sq yards * 9 sq feet/sq yd = 114,750 sq feet

3x² = 21

x² = 7

x = 2.65

Answer:

x = ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Given

3x² + 7 = 28 ( subtract 7 from both sides )

3x² = 21 ( divide both sides by 3 )

x² = 7 ( take the square root of both sides )

x = ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

You figure out if 476 is closer to 480 or 470 and in this case it is closer to 480, thus that is the answer. Same thing goes for the hundredes place just focusing your attention in the tens or hundreds place.   - Hope this helps :)

Answer: -9 = a(1 - 3)² + 3

Step-by-step explanation:

Vertex Form Equation:

y = a(x - h)² + k

vertex: (h, k) which means

h = 3

k = 3

because your vertex is (3, 3).

Your point is (1, -9) which is (x, y).

This means

x = 1

y = -9

Now, plug everything into your Vertex Form Equation:

-9 = a(1 - 3)² + 3

That’s your equation and final answer, but of course, if you need to, you can solve for a if you need to.

If a is positive, the parabola opens up. If a is negative, the parabola opens down.
