Question 1 read explanation. Question 2 it's c= 5. Question 3 it's 5 miles. Question4 it's
Step-by-step explanation:
For question 1 it's just asking you to make a right triangle with the segment as the hypotenuse. To do that make a dot on (5,1) and draw the triangle. A hypotenuse is the longest side of a right triangle, opposite the right angle.
For question 2 you just get the units of the triangle. The hypotenuse is always c (the segment). However, it's difficult to find c by just looking at the graph. That's why you plug in the other sides a = 3 and b = 4 (doesn't matter which way) to find c. So, you plug in 3^2 + 4^2 = c^2. This will give 9 + 16 = c^2, which is 25 = c^2. We need c not c^2! That means we square 25 to get 5. c = 5!
For question 3, you use the answer from question 2 I believe, so it's 5 miles.
For question 4, it's the same as question 1 so if it helps you make a visual on paper. Draw those two dots and to make a right triangle you'll also need the point (1,1). Find the units 8^2 + 10^2 = c^2. c = 2root41.

Which represents the arithmetic means of the following sequence: . . . , 3125, ___, ___, ___, 5? *
a. 2125, 1345, 565
b. 2345, 1565, 785
c. 2455, 1675, 895
Answers
Let's start off by defining our first term as u⁰
u⁰ is unknown,u¹=3124,u² is unknown,ect..
Using the recurring formula which states;
u(n+1)=u(n)+d
u¹=u⁰+d
u⁰=u¹-d
u⁰=3125-d
Using the explicit relation, which states;
u(n)=u⁰+nd
u⁵=u⁰+5d
5=3125-d+5d
4d=-3120
d=-780
u²=u¹-780=3125-780=2345
u³=2345-780=1565
u⁴=1565-780=785
You answer is letter C
The arithmetic means of the given sequence is 2455, 1675, 895
let the first term be u(0).
and, first term u(1) = 3124
We can use the recurring formula as:
u(n+1)=u(n)+d
u(1)=u(0)+d
and, u(0)=u(1)-d
and, u(0)=3125-d
Using the explicit relation
u(n)=u(0)+nd
u(5)=u(0)+5d
5=3125-d+5d
4d=-3120
d=-780
and, u(2)=u(1)-780
u(2) = 3125-780
u(2) = 2345
and, u(3)=2345-780
u(3) =1565
and, u(4)=1565-780
u(4) = 785

Create a totally different sequence that begins 10,2, ... For your sequence, write the next four terms and an equation for t(n). Cannot be arithmetic or geometric.
Answers
Answer: see below
Step-by-step explanation:
1) 10, 2, 1.2, 1.12, 1.112, 1.1112
[tex]t_n=\dfrac{t_{n-1}}{10}+1[/tex]
t₁ = 10
t₂ = 10/10 + 1 = 2
t₃ = 2/10 + 1 = 1.2
t₄ = 1.2/10 + 1 = 1.12
t₅ = 1.12/10 + 1 = 1.112
t₆ = 1.112/10 + 1 = 1.1112
2) 10, 2, -2, -4, -5, -5.5, ...
[tex]t_n=\dfrac{t_{n-1}}{2}-3[/tex]
t₁ = 10
t₂ = 10/2 - 3 = 2
t₃ = 2/2 - 3 = -2
t₄ = -2/2 - 3 = -4
t₅ = -4/2 - 3 = -5
t₆ = -5/2 - 3 = -5.5

Hailey purchased a new car in 2000 for $29,600. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $12,000 in the year 2007, then what would be the predicted value of the car in the year 2012, to the nearest dollar?
Answers
=========================================================
Explanation:
x = number of years since the year 2000
eg: x = 1 represents the year 2001
y = value of the car in dollars
The point (x,y) = (0,29600) is on the curve and it's the y intercept. This is when Hailey bought the car with a value of $29600.
Another point on this curve is (7,12000) to indicate seven years have passed and the car is now worth $12000.
------------------------------
Since the y intercept is 29600, this is the value of 'a' in the equation
y = a*b^x
Meaning we can update it to
y = 29600*b^x
Plug in the coordinates of the other point so we can solve for b
y = 29600*b^x
12000 = 29600*b^7
12000/29600 = b^7
b^7 = 12000/29600
b^7 = 0.405405
b = (0.405405)^(1/7)
b = 0.878991 approximately
------------------------------
We found that
a = 29600b = 0.878991 approximatelySo we go from
y = a*b^x
to
y = 29600*0.878991^x
To verify this, plugging x = 0 should lead to y = 29600
Also, plugging in x = 7 should lead to y = 12000 or very close to it.
------------------------------
The last step is to plug in x = 12 to find the car's value in 2012, i.e. x = 12 years after the year 2000.
So,
y = 29600*0.878991^x
y = 29600*0.878991^12
y = 6296.58182216087
y = 6297
The predicted car's value in 2007 is about $6297
what is the density of object X if the mass is 100g with a volume of 6
Answers
Answer:
4.0 g/ml
Step-by-step explanation:
[tex] Volume_X [/tex] = water displaced by X
Water displaced by object X = Final fluid level - Original fluid level
Water displaced by object X = 90 ml - 65 ml = 25 ml
[tex] Volume_{X} = 25 ml [/tex]
Density of rock:
100 grams => 25 ml
x grams => 1 ml
Cross multiply
x*25 = 1*100
25x = 100
25x/25 = 100/25
x = 4
Density of object X = 4 g per 1 ml = 4.0 g/ml

The mean of 30 test scores was 92. The range of scores was 10.
Answers
Answer:
First option.
Step-by-step explanation:
The mean of a set of data is all the data added together divided by the total numbers in that data set. So not only do you have to add an additional 45 to the data set, but you also have to divide the total of all the test scores by the total number of test takers which is now 31.
The range of a set of data is rearranging the data set smallest to largest and then subtracting the smallest from the largest value in the data set. Since the mean is 10 it's a small chance that 45 is either smallest or the largest of the set of data. We don't know the median, or the mode of the data set, nor does the question give us the other 30 test scores so it's between the range and the mean.
The most affected with the inclusion of the additional students test score would be the first option or the "mean."
Hope this helps.
Equations
Pls give an explanation
2x + 12 = 24
I don’t understand it thank you
Answers
Answer:
2x+12=24
first you subtract 12 from both sides
2x+12=24
-12. -12
The 12-12 should cancel itself, the rest of the equation you bring down to get
2x=12 (because 24-12=12)
Now you have 2x=12.
you then divide 2x by both sides.
2x=12
/2x=/2x
The 2x/2x cancels itself out so you then solve for 12/2x.
For this you just divide 12/2 which is 6!
x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!
hope this helps! :D

A bag contains 2 red marbles, 6 blue marbles and 7 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 100oth, that both marbles drawn will be red?
Answers
Answer:
0.01 (nearest hundredth)
Step-by-step explanation:
[tex]\mathsf{probability=\dfrac{number \ of \ favorable \ outcomes}{number \ of \ total \ outcomes}}[/tex]
Total number of marbles (total outcomes) = 2 + 6 + 7 = 15
⇒ Probability of the first marble being red = [tex]\dfrac{2}{15}[/tex]
As there is no replacement, the total number marbles is now 15 and there is only 1 red marble left.
⇒ Probability of the second marble being red = [tex]\dfrac{1}{14}[/tex]
So the probability of the 1st and 2nd marble being red is:
[tex]\dfrac{2}{15}\times \dfrac{1}{14} = \dfrac{1}{105}[/tex] = 0.01 (nearest hundredth)
