Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20

Gio ran 5 miles yesterday. This distance is 80% of the distance he planned to run.
How far did he plan to run? *
Answer:
Gio planned to 6 miles.
Step-by-step explanation:
this is because 5 - 80% = 1
which means he wanted to run 1 more mile
which also means that he planned to run 6 miles
A frog is sitting exactly in the middle of a board that is five feet long. Every ten seconds he jumps one foot to the left or one foot to the right, at random. You want to use simulation to estimate the probability that he jumps off the board in sixty seconds or less. (For example, if he jumps LLRLRL, he is still on the board, on the left-most square. If he jumps LLRLL, he has jumped off the board in fifty seconds.)
Required:
Describe how you would use the digits of a random number table to carry out this simulation.
Answer:
Since the Frog makes a Jump every 10 seconds
( using the digits on a random number table )
It will take 7 jumps with 2 jumps in reverse direction i.e. either left or right for the frog to be off the board in 60 seconds it will take 3 jumps in similar direction as well to get the frog off the board also 5 jumps with 1 jump in the opposite direction is what it will take to get the frog off the board as well within the time frame of 60 secondsStep-by-step explanation:
A frog sitting exactly in the middle of a board which is 5ft long : frog is 2.5 ft from the edge of the board
every 10 seconds the frog jumps ; L or R
If he jumps ; LLRLRL ( still on Board on the left-most square )
if he jumps ; LLRLL ( He is off the Board in fifty seconds )
Since the Frog makes a Jump every 10 seconds
( using the digits on a random number table )
It will take 7 jumps with 2 jumps in reverse direction i.e. either left or right for the frog to be off the board in 60 seconds it will take 3 jumps in similar direction as well to get the frog off the board also 5 jumps with 1 jump in the opposite direction is what it will take to get the frog off the board as well within the time frame of 60 secondsJoe wants to fence a rectangular pen for his goats. The length of the pen should be at least 60
ft, and the distance around should be no more than 260 ft. Which system of inequalities and
graph represent the possible dimensions of the pen?
Answer:
y>60
2*x+2*x<260
it's the only one that works
Step-by-step explanation:
The system of inequalities is x ≥ 60 and 2x + 2y ≤ 260.
The graph is given below.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Length of the rectangular pen = x
Width of the rectangular pen = y
Now,
x ≥ 60 _____(1)
Perimeter = 260
2 (x + y) ≤ 260
2x + 2y ≤ 260 _____(2)
The graph of (1) and (2) are given below.
Thus,
The system of inequalities is x ≥ 60 and 2x + 2y ≤ 260.
The graph is given below.

What is the area of the triangle?
Answer:
15/2
Step-by-step explanation:
Hello,
the area of a triangle is b*h/2
we can set BC as the base because AC is harder to calculate.
Then we draw an imaginary height.
There's no way to really explain, but the height would be 5 here, since 3 - -2 = 5
The base is 3
3*5/2 = 15/2

Find the area of the isosceles triangle formed by points of intersection of the parabolas y=-x2+9 and y=2x2+3 and the origin.
Answer:
10
Step-by-step explanation:
*I’m assuming that you meant y = 2x^2-3 because that is what my RSM problem was and it was exactly the same problem other than that.* First you want to find the points of intersection of the two parabolas. You can choose to graph them or do any other method. Anyways, the points of intersection are: (2,5) and (-2,5). You now want to add (0,0). So obviously (2,5) to (-2,5) is the base and it is 4 units. The height is 0 to 5 which is 5 units. Do (4*5)/2 and you get 10. Hope this helped you with your RSM and let me know if I assumed correctly.

no
Step-by-step explanation:
that is because syrus's age only increases instead of 2 each year, so their ages wont stay in propotion for another year. samira will be 7 and syrus will be 13.

The sum of my three digits is 13. My first digit
is 2 and my last digit is a multiple of 5. What
number am I?
Answer:
Step-by-step explanation:
Comment
The sum of the digits is 13.
The first digit is 2
The last digit is 0 or 5
Can it be zero?
2 + _ + 0 = 13
2 + 0 _ x = 13 Subtract 2 from both sides
2 - 2 + 0 + x = 13 - 2 Combine
x = 11
No there is no such thing as a digit is value is 11. So the last digit is 5
2 + __ + 5 = 13
7 + x = 13 Subtract 7 from both sides
7-7 + x = 13 - 7 Combine
x = 6
The middle number is 6

1,000+1,000= so 0 + 0 is 0 then 0 again then 1+1= 2 so 2,000
Answer:
Yes 1,000 + 1,000 = 2,000
Step-by-step explanation:
Because 1 + 1=2, 10 +10 =20, 100 + 100 = 200. So 1000 + 1000 = 2000
Also 0 + 0 = 0

Don and Ana are driving to their vacation destination. Upon entering the freeway they began driving at a constant rate of 60 miles an hour. Don noticed that 3 hours into the trip they were 650 miles from the destination.
How far from their destination will they be 3.7 hours since entering the freeway?
How far from their destination were they 2.3 hours since entering the freeway?
To solve the problem we must know about Speed, distance, and Time.
What are Speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Speed = 60 miles an hour
Don noticed that 3 hours into the trip they were 650 miles from the destination.
Distance traveled by them in 3 hoursWe know that Don and Ana are traveling at a constant speed and they are traveling for 3 hours.
[tex]\rm Distance= \rm speed \times Time[/tex]
[tex]\rm Distance = 60 \times 3 = 180\rm\ miles[/tex]
Thus, Distance traveled by them in 3 hours is 180 miles.
Total Distance from their destinationWe know that Don and Ana are traveling on the freeway for the past 3 hours and they are still 650 miles away, therefore,
Total Distance from their destination
= Distance traveled by them in 3 hours + 650 miles
= 180 miles + 650 miles
= 830 miles
Thus, the distance traveled by then is 830 miles.
A.) Distance between them and destination after 3.7 hours since entering the freeway,
Distance traveled by them = speed x 3.7
= 60 x 3.7 = 222 miles
Distance between them and the destination= Total Distance from their destination - Distance traveled by them
= 830 miles - 222 miles
= 608 miles
Thus, they are 608 miles far from their destination.
B.) Distance between them and destination after 2.3 hours since entering the freeway,
Distance traveled by them = speed x 2.3
= 60 x 2.3 = 138 miles
Distance between them and the destination= Total Distance from their destination - Distance traveled by them
= 830 miles - 138 miles
= 692 miles
Thus, they are 692 miles far from their destination.

find sinx given cos2x=5/9
Answer:
sinx = √2/3
Step-by-step explanation:
cos2x = 1-2sin²x
5/9 = 1-2sin²x
2sin²x =1-5/9
2sin²x = 4/9
sin²x = (4/9)/2
sin²x = (4/9)*(1/2)
sin²x = 2/9
sinx = √2/3
