complete the table for values for y=x^2-x-2
Answer:
x -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2
Step-by-step explanation:
The given equation is y=x²-x-2.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
We need to find the y values of the give x values.
Given that, x = -3 -2 -1 0 1 2 3
When x = -3, y = (-3)²-(-3)-2
= 9+3-2 = 10
When x = -2, y = (-2)²-(-2)-2
= 4+2-2
= 4
When x = -1, y = (-1)²-(-1)-2
= 1+1-2
= 0
When x = 0, y = 0²-0-2
= -2
When x = 1, y = 1²-1-2
= -2
When x = 2, y = 2²-2-2
= 0
When x = 3, y = 3²-3-2
= 4
So, the complete table is
х -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2 0 4
There, the y values of the given x values in the given equation is y = 10, 4, 0, -2, -2, 0, 4.

Stephen calculated the linear regression equation to be y = -7.8x + 246.3. Using this equation, find the cost of a
room 5 city blocks away from Time Square.
1) $195
2) $207
3) $238
4) $285
What’s the answer?
Answer:
$207
Step-by-step explanation:
Given the following :
Data:
X : Distance From Times Square (city blocks)
Y: Cost of a Room (dollars) (y)
The linear regression model generated for the data :
y = -7.8x + 246.3
y = predicted variable ; - 7. 8 = slope of model ; x = predictor variable ; 246.3 = intercept
Using the model:
The cost of a Room 5 block away :
x = 5
y = -7.8(5) + 246.3
y = - 39 + 246.3
y = $207.3

Answer:
Step-by-step explanation:
The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.
Find the slope of the line through the points (3,2) and (4,5).
Answer:
The answer is 3Step-by-step explanation:

John caught 24 trout in bass while on a fishing trip. The total weight of his catch was 137 pounds. The average weight of a trout was 2.5 pounds, and the average weight of a bass was 8 pounds. How many trout and how many bears did he catch?
Answer:
trouts = 10 and bears = 14
Step-by-step explanation:
Let number of trouts and bears be x and y respectively.
This means that since he caught 24 trout and bass, we have;
x + y = 24 - - - (eq 1)
Now, average weight of trout is 2.5 pounds and average weight of bass is 8 pounds.
Thus;
2.5x + 8y = 137 - - - (eq 2)
From eq(1), let's make x the subject.
Thus;
x = 24 - y
Put 24 - y for x in eq(2)
2.5(24 - y) + 8y = 137
60 - 2.5y + 8y = 137
5.5y + 60 = 137
5.5y = 137 - 60
y = 77/5.5
y = 14
x = 24 - 14
x = 10
Thus, trouts = 10 and bears = 14

What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?
Answer:
4.53%
Step-by-step explanation:
We are told that:
From the question, we have a 6.5 % coupon
Hence = 6.5 × $10
= $65
Price of the bond one year later = $1,037.19
$1,054.47 - $1,037.19
= $17.28
Rate of Return
= ($65.00 - $17.28)/$1,054.47
47.72 ÷ 1054.47 = 0.045254962
0.045254962 × 100 =
4.5254962 %
Approximately = 4.53%

Can any kind soul help me please
Answer:
(i) we will be finding the acceleration here, in the first 20 seconds the velocity was 10
a = velocity/time
a = 10/20
a = 0.5 ms -2
(ii) difference in distance of the bus and bicycle will be given by formula of velocity
velocity of bicycle
10 * 80 = distance
800 metres
velocity of bus
for first 20 seconds( distance= velocity* time)
200 metres
from 20 seconds to 60 seconds, it will be for 40 seconds
then distance will be,
400 metres
final 20 seconds
200 metres
adding the distances of bus it will be 800 metres.
the difference in distance will be 0 metres.

2. Tina uSUally brings her children every Sunday afternoon at the children's park in their barangay. The park is 350m Iong and 200m wide complete with slides and
swings for children to play. If is surounded by a pathway of unifom width for children who loves biking and jogging. Suppose the total area of the park and the pathway is 74,464 m2.
a. How wide is the pathway of the park?
b. If you were Tina, woulad you like your children fo go biking and jogging in that park?
Answer: kindly check explanation
Step-by-step explanation:
Given the following :
Total area of parknand path way = 74,464 m2.
Dimension of park = 350m by 200m
Using the area of rectangle formula:
Area = Length * width
Area of park = 350m * 200m
Area of park = 70,000
Area of path = (74,464 - 70,000) = 4,464m2
Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m
2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path
