Step-by-step explanation:
Multiply each term of (x² + 2x - 1) by x and multiply each term of (x² + 2x - 1) by 3
Area of parallelogram = bh
= (x² + 2x - 1)(x + 3)
= (x² + 2x - 1)*x + (x² + 2x - 1)*3
=x²*x + 2x*x - 1*x + x²*3 +2x*3 - 1*3
= x³ + 2x² - x + 3x² + 6x - 3
= x³ + 2x² + 3x² -x + 6x - 3
= x³ + 5x² + 5x - 3

Step-by-step explanation
Im not sure if its correct
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = √156
b = 12.48
b= 12 ( If needed to round to the nearest whole number)
a^2 + 15^2 = 20^2
a^2 + 225 = 400
a^2 = √175
a = 13.22
a = 13 ( If needed to round to nearest whole number)

A show pony weighs at least 900 pounds. After a recent weigh in, the owner of a show pony amended the diet of his pony, increasing the animal's caloric intake, with the hope that the pony would gain weight to be shown in a few months. The data shown in the table and scatter plot below represents the pony's additional daily caloric intake and recorded weight gain (in pounds) of the show pony over the last ten weeks.
Additional Daily Calories Consumed Weight Gained
(in pounds)
1,500 3
1,575 7
1,650 3
1,725 4
1,800 8
1,875 9
1,950 13
2,025 7
2,100 17
2,175 15
Part A: Use the data shown in the table and scatter plot to create an approximate equation for the line of best fit.
Part B: In complete sentences, describe the show pony's weight gain in terms of the units used in the data.
Part C: According to the equation for the best fit line for the data, approximately how much weight would you expect the pony to gain in a week if its additional daily caloric intake for that week is 2,300 calories?
An approximate equation for the line of best fit is y-hat = 0.018x - 24.5111.
How to explain the equation?A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where
y-hat is the predicted value for the recorded weight gain (in pounds)
x is the additional daily caloric intake.
b) The pony's additional calorie intake increases, the weight gain also increases in pounds
c) Set x equal to 2300 and solve for y-hat:
y-hat = 0.018x - 24.5111
y-hat = 0.018(2300) - 24.5111
y-hat = 41.4 - 24.5111
y-hat = 16.8889
Therefore, the predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.

Step-by-step explanation:
The question is incomplete, as the required lengths are not given.
I will use the following data set to answer the question.
[tex]Dataset: 35, 51, 39, 42, 68, 62, 32, 59[/tex]

[tex]Range = 68 - 32[/tex]
[tex]Range = 36[/tex]
Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval
[tex]Class= Range/10[/tex]
[tex]Class = 36/10[/tex]

Answer: See below
Step-by-step explanation:
1) 1/2 x 3.14 x 35^2
1/2 x 3.14 x 1225
1/2 x 3846.5
A = 1923.25 yd^2
2) (3.14)r^2
(3.14) (35)^2
3846.50 yd^2
3) P = d + (3.14)r^2
P = 70 + (3.14) (35)
P = 70 + 109.90
P = 179.90 yd
4) P = 2( l + w)
P = 2 (70 + 100)
P = 2 (170)
P = 340
Perimeter of the square minus the perimeter of the circle.
340 - 179.90 = 160.10 yd

Answer:
Dave and Anna:
1. Income highlight:
combined take home pay of $900/week
Total income: 4(900) - because 4 weeks in most months = $3600
-----------------------------
2. Expense highlights:
bi-weekly mortgage of $675
property taxes of $1800
Car expenses $160
Car insurance: $128
House insurance: $35
Saving for kids: $200
-------------
Expense calculations:
Mortgage bi-weekly = 675 x 2 = $1350/month
Property taxes = 1800/12 months/year = 150/month
everything else is already monthly
1350 + 150 + 160 + 128 + 35 + 200 = 2,023
---------------------------------------
income - expenses
$3600 - 2023 = $1,577 surplus

The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B. The set out outputs is {7, 2, 6, -6|, which is in Option B.
Two fair, six-sided dice are rolled. What is the probability that the resulting total is even or greater than 10?
Answer:
Step-by-step explanation:
Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.
The probability that the resulting total is even or greater than 10 is 7/12.
Given that, two fair, six-sided dice are rolled.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here, sample space of two dice is
S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6), (2,1),(2,2),(2,3),(2,4),(2,5),(2,6), (3,1),(3,2),(3,3),(3,4),(3,5),(3,6), (4,1),(4,2),(4,3),(4,4),(4,5),(4,6), (5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}
Number of favorable outcomes = 18
Total number of outcomes = 36
Probability of getting the total is even = 18/36
= 1/2
Number of favorable outcomes = 3
Probability of getting the total is greater than 10 = 3/36
= 1/12
So, probability is 1/2 + 1/12
= 6/12 + 1/12
= 7/12
Therefore, the probability that the resulting total is even or greater than 10 is 7/12.

Jason has saved 41% of what he needs to buy a 73$ skateboard . Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Answer:
No, Jason did not solve correctly
Step-by-step explanation:
Jason has saved 41% of what he needs to buy a 73$ skateboard.
Jason found out 50% of 70 is the same things as 70 divided by .50= 140. So he has more than enough to purchase the skateboard. Did he solve correctly
Let compare both statements
50% of 70 = 70 ÷ 0.5 (140)
50% × 70 = 140
50/100 × 70 = 140

You are in your backyard with your pets. In one area, you count 108 legs. You count 41
animals. You have a combination of bunnies and chickens. How many of each type of animal do
you have?
Write a system of equations (make sure to define your variables first!), and then solve
this problem. Then, solve in a different way.
Answer:
Bunnies= 13 Chickens=28
Step-by-step explanation:
Let's put
x = bunnies------4 legs
y = chickens-----2 legs
x + y = 41----------------x= 41-y
4x+ 2y = 108
replace in 2nd equation
4(41 - y) + 2y = 108
164 - 4y + 2y = 108
2y = 56
y = 56/2= 28
x = 41 - 28= 13

3. When should points of intersection be included within the feasible region of a system of nonlinear inequalities
and why
Answer:
Points of intersection should be included within the feasible region (the solution set) of a system of nonlinear inequalities when the boundary lines that create the point are solid. A dashed line indicates that the points are not included in the solution set. Therefore, if one boundary line is dashed and one is solid, the point of intersection will not be included within the feasible region.
Step-by-step explanation:
Points of intersection should be included within the feasible region of nonlinear inequalities when the boundary lines that create the point are solid.
What is Inequality?This is defined as an expression in which the sides are not equal to each other.
The presence of boundary lines which have dashed and solid ones, the point of intersection will not be included within the feasible region.
