Answer:
3 seconds
Step-by-step explanation:
Given the height modelled by the function
h(t) = -16t² + 16t + 96
The hit the water at h(t) = 0
0 = -16t² + 16t + 96
Divide through b y -16
0 = t² - t - 6
t² - t - 6 = 0
t² - 3t+2t - 6 = 0
t(t-3)+2(t-3) = 0
t+ 2 = 0 and t - 3 = 0
t = -2 secs and t = 3secs
Since t can't be negative, hence;
t = 3 secs
hence it will take 3 seconds until Devon hit the water

what is the slope and equation of a line perpendicular to the x-axis passing through point (-4 3)
Answer:
the slope of the line is undefined, and the equation is x = -4
Step-by-step explanation:
The slope of a vertical line is undefined .
What is slope with example?
The slope-intercept form of an equation is used to represent each time the equation of a line is stated as y = mx + b. M represents the line's slope. Additionally, b is the b in the y-intercepting point (0, b). For instance, the y-intercept is at (0, 7) and the slope is 3 in the equation y = 3x - 7.given ,
the point ( -4 , 3 )
x = -4 , y = 3
A line perpendicular to the x-axis is generally described by the equation x=a, where an is a real number. It is also known as a vertical line.
This line equation is x= -4 because you are seeking for a vertical line that goes through the point (x, y)=(-4 , 3) in your diagram.
in this question we are finding equation of line which is perpendicular to x - axis .
but for the equation of line we need to slope , that is not given in this question .
The slope of a vertical line is undefined .

A ball is thrown from a point 6 metres above the ground. The graph shows the height of the bake above the ground in metres. Estimate the speed of the ball in m/s after 1 second. You must show working.
Answer:
1.38
Step-by-step explanation:
1.7-0.4=1.8
1.8/1.3=1.38
On graph place point at (1,8) and draw a triangle
The speed of the ball is 2 m/s.
What is Speed?
The speed of the object is calculated as,
Speed = Distance / Time
Given that;
A ball is thrown from a point 6 meters above the ground.
The graph shows the height of the bake above the ground in meters.
Now,
Draw the line perpendicular to both the x - axis and y - axis for 0 to 1 second.
So, we get;
Value of y - coordinate = 2 m
Value of x - coordinate = 1 m
Thus, Speed of the ball = Distance / Time
= 2 / 1
= 2 m/s
So, The speed of the ball is 2 m/s.

The figure below is a regular octagon with a side length of 8 inches.
8 inches
To the nearest square inch, what is the area of the figure?
309
118
64
49
Answer:
309in²
Step-by-step explanation:
Area of an octagon is expressed as;
A=2(1+√2)a²
a is the side length of the octagon
Given
a = 8
Substitute into the formula
A = 2(1+√2)(8)²
A = 2(1+√2)(64)
Expand
A = 2(64+64√2)
A = 128+128√2
A = 128+128(1.414)
A = 128+181.01
A = 309in²
Hence the area of the octagon is 309in²

Find the independent variable and dependent and write an equation (gr 9 hw) 1) To fix a car, Fix-it Auto charges a base fee of $20 plus $40 per hour. 2) The cost of a banquet at Jean's Banquet Hall is $450 for the rental of the hall and $15 per guest. 3) An author earns a royalty of $1.25 for each book sold. 4) Marie has $500 in her bank account. Each week she plans to deposit $20.
Answer:
Step-by-step explanation:
Using the regression equation :
y = mx + c
y = dependent variable ; x = independent variable ; m = slope ; c = intercept
1.) base fee = $20 ; hourly charge = $40
Hourly charge = independent
Total charge = dependent
Total charge = 40x + 20
x = Number of hours
2.) rental fee = $450; charge per guest = $15
Total rental fee = dependent
Independent = $15 = charge per guest
Number of guest = x
Total fee = 15x + 450
3.)
Royalty earned = dependent variable
Cost per book = $1.25 = independent
Royalty earned = $1.25 * number of books
4.)
Amount deposited per week = $20 = independent variable
Amount in account = dependent variable
y = 500 + 20x
x = number of weeks

Answer:
64
Step-by-step explanation:
Answer:
A = 25x^2 + 30x + 9
Step-by-step explanation:
A = (5x+3) * (5x+3) or A = (5x+3)^2
A = 5x*5x + 5x*3 + 5x*3 + 3*3
A = 25x^2 + 15x + 15x + 9
A = 25x^2 + 30x + 9

can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4

A recipe for 24 cookies calls for 4 tablespoons of sugar. If you make 40 cookies and use 5 tablespoons, will the cookies taste the same? Explain
Answer:
Step-by-step explanation:
No, because they wouldn't contain the same amount of sugar per cookie
for the first recipe - 24 cookies with 6 tablespoons
thats 6/24 so 0.25 tablespoons of sugar per cookie
for the second recipe - 36 cookies with 10 tablespoons
thats 10/36 so 0.276 tablespoons per cookie
the cookies in the second recipe would be slightly sweeter than the cookies in the first
