__________________________________________________________ The surface area of the triangular prism is (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh
For this question,
you know that the perimeter of the base is 6+10+8 which is 24.
and the length of the prism is 22,
so (22x24) + Base Area which is (6x8)/2-> 24x2
(22x24)+(24x2)= 528 + 48 = 576
so your answer is 576

Answers
The values of x and y are 7 and 12 respectively
Solving simultaneous equationsFrom the question, we are to determine the values of x and y
From the given information,
Line AB and Line CD bisect each other at point E
Then, we can conclude that
AE = BE
and
CE = DE
From the given information,
AE = 3x - 10y + 123
BE = -2x - 7y + 122
CE = 9x + 10y - 171
DE = 3x + 20y - 249
Then, we can write that
3x - 10y + 123 = -2x - 7y + 122
Simplifying
3x +2x -10y + 7y = 122 -123
5x -3y = -1 ----------- (1)
Also,
9x + 10y - 171 = 3x + 20y - 249
Simplifying
9x -3x +10y -20y = -249 + 171
6x -10y = -78 --------- (2)
Now, solve equations (1) and (2) simultaneously
5x -3y = -1 ----------- (1)
6x -10y = -78 --------- (2)
Multiply equation (1) by 10 and equation (2) by 3
10 × ( 5x -3y = -1
3 × ( 6x -10y = -78
50x -30y = -10 ----------- (3)
18x -30y = -234--------- (4)
Then, subtracting equation (4) from equation (3), we get
50x -18x -30y-(-30y) = -10-(-234)
32x -30y + 30y = -10 + 234
32x = 224
∴ x = 224/32
x = 7
Put the value of x into equation (1), to find y
5x -3y = -1
5(7) -3y = -1
35 -3y = -1
35 + 1 = 3y
36 = 3y
∴ y = 36/3
y = 12
Hence, the values of x and y are 7 and 12 respectively

Answers
Answer:
P =2(x+ y) [tex]ft[/tex].
A =xy [tex]ft^{2}[/tex]
Step-by-step explanation:
perimeter of rectangle (P)= 2(L+B
Area of rectangle (A) = L×B
Given,
width = 'x'
length = y = x+20
therefore using above formula
P = 2(x+20 + x) = 2(2x+20)
A = (x+20)(x)
cost of land per square foot = $12
cost of land per linear foot = $8
total cost of land = $10560
now,
P×8 + A×12 = 10560
2(2x+20)×8 + (x+20)(x)×12 = 10560
32x + 320 + 12x²+ 240x = 10560
12x² + 272x = 10240
12x² + 272x - 10240 = 0
solving this quadratic equation using Discriminant method
x = [-b ±√(b² - 4ac)]/2
where b is the coefficient of x
a is the coefficient of x²
and c is the constant term
by replacing values in the above formula
x = 19.5 , x = -42.24
as the area cannot be negative therefore -42.24 is neglected

Does this graph represent a proportional relationship? Explain.
On a coordinate plane, a curved line has 2 curves.
Answers
Answer:
No, This graph does not show a proportional relationship. The graph of a proportional relationship is a straight line that passes through the origin.
Step-by-step explanation:
If the graph of a relationship is a line or a ray passes through the origin, then it is proportional. If it is a line or ray that does not pass through the origin, then it is not proportional.
So, it's clear that if a graph has to be proportional then the relationship between the variables should be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
Given relationship is not proportional because they do not have a constant ratio nor does it pass through the origin. If the data on the graph shows a curved line, it is not constant and is not proportional.

If inspection department wants to estimate the mean amount with 95% confidence level with standard deviation 0.05 then it needed a sample size of 97.
Given 95% confidence level, standard deviation=0.05.
We know that margin of error is the range of values below and above the sample statistic in a confidence interval.
We assume that the values follow normal distribution. Normal distribution is a probability that is symmetric about the mean showing the data near the mean are more frequent in occurence than data far from mean.
We know that margin of error for a confidence interval is given by:
Me=[tex]z/2* ST/\sqrt{N}[/tex]
α=1-0.95=0.05
α/2=0.025
z with α/2=1.96 (using normal distribution table)
Solving for n using formula of margin of error.
[tex]n=(z/2ST/Me)^{2}[/tex]
n=[tex](1.96*0.05)^{2} /(0.01)^{2}[/tex]
=96.4
By rounding off we will get 97.

Answers
An equation that models the height of the ball as a function of time t is; h(t) = -16t² + 40t + 3. The maximum height that the ball will reach is 28 ft
How to Solve the Vertical velocity model?We are given the equation for the vertical velocity model as;
h = -16t² + vt + s
Where;
v = velocity
s = starting height
h = ending height
t = time
A) From the question, we have;
v = 40 ft/s
s = 3 ft
Thus, the equation is;
h = -16t² + 40t + 3
B) To find the time that the ball reaches its maximum height, we will equate the height equation to zero and find the roots. Thus;
-16t² + 40t + 3 = 0
Using an online quadratic equation calculator gives;
t = 2.573 s
C) The maximum height that the ball will reach is;
h'(t) = -32t + 40
At h'(t) = 0;
-32t + 40 = 0
32t = 40
Thus;
t = 1.25 s
Max height = -16(1.25)² + 40(1.25) + 3
Max height = 28 ft
D) The height of the ball after 2 seconds is;
h(2) = -16(2)² + 40(2) + 3
h(2) = 19 ft
E) Time for the ball to hit the ground is;

Given:
y = 1.6 when x = 0.5Substitute the given values into the found equation and solve for k:

Each ticket costs 32 dollars, so the debt for one ticket is -$32. The tour company adds a 15-dollar fee for the entire order.
