A cannon ball has been catapulted through the air and follows the path created by the
function f(t) = -16t2 + 30t + 7 where f(t) is the height of the cannon ball in
meters at any given time (t) in seconds.

Answers

Answer 1

Answer:

the cannon ball's maximum height is 21 meters rounded to the nearest whole number

Step-by-step explanation:

Answer 2

The maximum height of the cannonball will be 21.06 meters when the time t = 0.9375 seconds.

What is the parabola?

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

A cannonball has been catapulted through the air and follows the path created by the function given below.

f(t) = -16t² + 30t + 7

where f(t) is the height of the cannonball in meters at any given time (t) in seconds.

Then the height of the cannonball will be given by the differentiation. Then we have

[tex]\rm \dfrac{d}{dx} f(t) = -16t^2 + 30 t + 7 \\\\\\\dfrac{d}{dx} f(t) = -32t + 30[/tex]

Then again differentiate to check whether the value is maximum or minimum.

[tex]\rm \dfrac{d^2}{dx^2} f(t) = -32t + 30\\\\\\\dfrac{d^2}{dx^2} f(t) = -32\\\\\\\dfrac{d^2}{dx^2} f(t) < 0[/tex]

Then the value of the height will be maximum for f'(t) = 0.

         f'(t) = 0

-32t + 30 = 0

             t = 30/32

             t = 0.9375

Then the maximum height will be

f(t) = -16(0.9375)² + 30(0.9375) + 7

f(t) = -14.0625 + 28.125 + 7

f(t) = 21.0625

f(t) = 21.06 meters

The area of a square in square feet is represented by z^(2)+12z+36. Find an expression for a side length of the square.

Answers

Answer:

Side is equal to [tex](z+6)[/tex] feet.

Step-by-step explanation:

A square is a four sided polygon in which all sides are equal, diagonals are equal and each angle is equal to [tex]90[/tex]°

Area of a square = side × side

Area of a square [tex]=z^2+12z+36[/tex]

Here, write [tex]12z=6z+6z[/tex]

Therefore,

Area of a square [tex]=z^2+6z+6z+36[/tex]

[tex]=z(z+6)+6(z+6)[/tex]

[tex]=(z+6)^2[/tex] square feet

So,

side × side [tex]=(z+6)^2[/tex]

This implies side is equal to [tex](z+6)[/tex] feet.

−3x − 5 = 16

−4(y − 2) = 12

Answers

Answer:

Step-by-step explanation:

First equation:  −3x − 5 = 16

 Combine the constants:

 -3x = 21

  Solve for x using division:  x = 21/(-3)   or  x = -7

Second equation:  −4(y − 2) = 12

 Reduce this by dividing both sides by -4:  y - 2 = -3

 Add 2 to both sides, to isolate y:  y = -1

Answer:

Step-by-step explanation:

Log_(32)8 = m

write is as

32^m=8

(2^5)^m = 2^3

2^5m = 2^3

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

5m = 3

divide 5 on both sides to remove it from m

m= 3/5

The value of m is [tex]\frac{3}{5}[/tex].

What is logarithm?

'Logarithm is the exponent or power to which a base must be raised to yield a given number.'

According to the given problem,

⇒ [tex]log_{32}8[/tex] = m

⇒ m = [tex]log_{32}8[/tex]

⇒ m = [tex]\frac{log 8 }{log32}[/tex]

⇒ m = [tex]\frac{log(2)^{3} }{log(2)^{5} }[/tex]

⇒ m = [tex]\frac{3log2}{5log2}[/tex]

Thirty-six members of the middle school choir, which represents 30%, participated in the regional contents. How many total students are in the choir?

Answers

Answer:

120

Step-by-step explanation:

Given data

36 members are equivalent to 30%

Let the total number of students  be x

Hence

30% of x= 36

30/100*x= 36

0.3x= 36

divide both sides by 0.3

x= 36/0.3

x= 120 students

Hence the total number of students is 120

5. What is the range of the function y = 2x – 4?

Answers

Answer:

The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.

graph is linear:

y=2x-4

solve for x=o

y=2x0-4       Eliminate 0

y=-4             solved for y

solve for y=0

0=2x-4          add 4

+4      +4

A water tank holds 944 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,180 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

Answers

Answer:

59

Step-by-step explanation:

The equation is

944 - 5x = 1180 - 9x

Notice what is being said. You start with 944 gallons and take off 5 per week

You also start with 1180 gallons and take on 9 per week.

You want to know when the two are equal. The second tank is larger, but it leaks more. That's what's going to bring about equality.

Add 9x to both sides

944 - 5x + 9x = 1180

944 + 4x = 1180                

Subtract 944 from both sides.

4x = 1180 - 944

4x = 236      

Divide by 4

x = 236/4

x = 59 weeks
