Answer:
the cannon ball's maximum height is 21 meters rounded to the nearest whole number
Step-by-step explanation:
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.
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
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:
y = -x/16 +1
Step-by-step explanation:
The slope is at any point x is ...
y' = -4/x^2
so, at x=8, the slope is ...
m = -4/8^2 = -4/64 = -1/16
The point-slope form of the equation of the line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Then the line with slope -1/16 through point (8, 1/2) is ...
y - 1/2 = -1/16(x -8)
y = -1/16x +1/2 + 1/2 . . . . . eliminate parentheses, add 1/2
y = -1/16x +1 . . . . . equation of the tangent line

Mrs. Fulcher had 14 gallon of milk, and she bought 12 gallon more. Her family then drank 58 gallon of milk. How much milk does Mrs. Fulcher have left?
Answer:
Mrs. Gallon is left with -22 gallon of milk
Step-by-step explanation:

Milk left with Mrs. Fulcher = 14 + 12 -58 = -22
(vii) log32 8=m
Again please
Answer:
log_(32)8= 3/5
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
Hope this helps!
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]
⇒ m = [tex]\frac{3}{5}[/tex]
Hence, we can conclude, the value of m is [tex]\frac{3}{5}[/tex].

Median = 3500
Step-by-step explanation:
Data Set: 1850, 3500, 4200, 2310, 4260
=> Let's set this to the ascending order (least to greatest) first:
1850, 2310, 3500, 4200, 4260
=> Now as you cancel out the first value, cancel out the last one, and do this until u reach down to only one number:
So our median = 3500

Thirty-six members of the middle school choir, which represents 30%, participated in the regional contents. How many total students are in the choir?
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?
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
4=2x divide by 2
/2 /2
4/2 =x
2=x solved for x
calculate the slope
Solve for x=1
y=2x1-4
y=2-4

Calculating the slope

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?
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

The school store sells markers for $0.35 each and pencils for $0.15
each. Anthony spent $2.80 to buy a total of 12 markers and pencils. How
many markers did Anthony buy?
PLEASE HELP !
Answer:
x = 5 pens
y = 7 pencils
Step-by-step explanation:
let
x = the number of pens
y = the number of pencils
Anthony spent $2.80 to buy a total of 12 pens and pencils
0.35x + 0.15y = 2.80
x + y = 12
by solving the system of equations
0.35x + 0.15y = 2.80
x + y = 12
we find
x = 5 pens
y = 7 pencils
