Answer:
h(3)=20
Step-by-step explanation:
h(3)=h(3-2)*h(3-1)=h(1)*h(2)=-10*-2=20
Answer:
20
Step-by-step explanation:
h(1) = -10
h(2) = -2
h(n) = h(n-2) * h(n-1)
Let n=3
h(3) = h(3-2) * h(3-1)
= h(1) * h(2)
= -10 * -2
= 20

Answer:
-25 feet
Step-by-step explanation:
We know that the change in altitude for the air balloon is -1500 feet, all within a span of 60 minutes, which then we are asked what is the rate of change.
To find the rate of change, we have to be able to divide a number by both sides that will not give us a decimal or very odd number. To avoid getting a decimal, divide both sides by 60.
-1500/60 = -25
60/60 = 1
So the rate of change would be -25 feet

Step-by-step explanation:
one-half of the people at a game wore hats. two-thirds of those people also wore gloves. one-fourth of those people wearing gloves and hats also wore scarves. 25 of the people had hats and scarves but no gloves. One hundred people had only scarves. If there were 1824 people, how many had scarves
Please give answer as soon as possible
Final Answer: 277 people had scarves.
Step-by-step explanation:
1/2 people wore hats2/3 people wore also wore gloves.1/4 people wore scarves.25 people had hats and scarves. (no gloves)100 people have only scarves.1824 people total1824 / 2 = 912 (Divide by 2 to get the people wearing hats)
912 / 3 = 304 (subtract 304 to get 2/3)
912-304 = 608
608/4 = 152. (people who wore gloves, hats, and scarves.)
152+100+25= 277

Which expression is equivalent to _?
Answer:
2^-1
Step-by-step explanation:
2^2 *2 / 2^4
We know that 2^2 * 2 = 2^2 *2^1
a^b*a*c = a^(b+c) so 2^2*2*1 = 2^(2+1)+ 2^3
2^3 / 2^4
We know that a^b / a^c = a^(b-c)
2^3 /2^4 = 2^(3-4) =2^-1
The equivalent of the given expression 2² × (2/2⁴) when simplified is; 2⁻¹
How to simplify exponents?We are given the exponents expression;
2² × (2/2⁴)
Let us first multiply out the numerator to get;
2² × 2 = 2³
Thus, our overall expression is;
2³/2⁴
According to laws of exponents;
a^(b)/a^(c) = a^(b-c)
Thus;
2³/2⁴ = 2³⁻⁴
⇒ 2⁻¹

What evidence supports a conservation law?
Carbon dioxide becomes glucose and oxygen during photosynthesis.
Hydrogen is made from the breakdown of carbon dioxide during photosynthesis.
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Glucose and oxygen become carbon dioxide and water during photosynthesis.
Answer:
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Step-by-step explanation:
Three forms of energy come into play in the functioning of an ecosystem:
* the electromagnetic radiation of short-wavelength (light),
* the electromagnetic radiation of long-wavelength (infrared: heat),
* chemical energy (in the form of organic molecules: sugars, etc.).
The conversion of light energy into chemical energy takes place in plants: it's photosynthesis.
Answer:
Carbon dioxide react with water and becomes glucose and oxygen during photosynthesis.
Step-by-step explanation:
6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, form glucose and oxygen.( during photosynthesis carbon dioxide and H2O in presence of sunlight and chlorophyll form glucose and oxygen)

Answer: 45 units
Step-by-step explanation:
Find the coordinates of R and S
R = -25
S = 20
Then just subtract them to find the distance between them.
20 - (-25) = 45.
Answer:
45
Step-by-step explanation:
First, find out the specific locations of R and S: for R, it is-25, and for S, it is 20 (use the tick marks on the x-axis).
Next, to find out the distance between R and S, be sure to add the absolute value, rather than the actual numbers.
So, ∣R∣ + ∣S∣ = 25 + 20 = 45

A map is drawn to a scale of 1 : 20 000.
The actual area of the grassland is 2.5 hectares. Calculate the area on the map, giving your answer in square centimetres. ( 1 hectare = 10 000 m² )
pls help thank you:>
Answer:
0.625 cm²Step-by-step explanation:
Scale factor:
k = 1/20000When applied to the area consider k² as a scale factor.
The actual area:
2.5 hectares = 25000 m² = 25000*100² cm² = 250000000 cm²The area on the map:
250000000 * (1/20000)² = 0.625 cm²what are two different ways to solve 257+438
Answer:
Two ways to solve is to just do column addition or split 200+50+7 and add it to 400+30+8 first add 200+400 = 600, 50+30=80, 7+8 = 15. Add 600+80+15= 695.

Determine the rule for the number pattern and use it to find the missing values.
Which of the following statements are true about the pattern above?
Select all that are true.
3,7,15 , , , ,....
The 10th term in the pattern will be 30.
Each term in the pattern will be a multiple of 3.
Each term in the pattern will be prime.
Each term in the pattern will be odd.
9514 1404 393
Answer:
Each term in the pattern will be odd.
Step-by-step explanation:
The first differences are ...
7 -3 = 4
15 -7 = 8
These differ by 4, and the second is double the first.
These relationships between the first differences give rise to two possible sequences: a) an exponential sequence; b) a quadratic sequence. We can use a graphing calculator to find the coefficients of each of the patterns.
Exponential Sequence
a[n] = 2·2^n -1
The sequence is 3, 7, 15, 31, 63, 127, 255, 511, 1023, 2047.
The 10th term is 2047.
Quadratic Sequence
a[n] = 2n^2 -2n +3
The sequence is 3, 7, 15, 27, 43, 63, 87, 115, 147, 183.
The 10th term is 183.
__
Based on the above, the only thing we can say about these sequences is that they are all odd numbers.
Clearly, the 10th term is not 30. 7 is not a multiple of 3, so that observation fails immediately. 15 is not prime, so that observation also fails immediately.
_____
Additional comment
The differences of first differences are called "second differences". The differences of those are "third differences". and so on. If you keep taking differences of a sequence described by a polynomial, the n-th differences being constant means the sequence is described by an n-th degree polynomial.
Here, if we assume the 2nd differences are constant at 4, then the sequence is described by a 2nd-degree polynomial. (Similarly, constant first-differences are described by a 1st-degree polynomial--a linear function.)
If sequential levels of differences are all exponential sequences, then the sequence itself is an exponential sequence. As here, it may have a vertical offset. The base of the exponential will be the common ratio of the differences. (Here, the first differences have a ratio of 8/4 = 2, so the sequence could be exponential with a base of 2.)

5 (88)
8 (63)

Answer:
I think the answer is 21
Step-by-step explanation:
The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.
Answer:
21
Step-by-step explanation:
14 : w = 26 : 39
w = 14 * 39 : 26

Divide the number of contestants by 4 and when there is 120 contestants there is 30 winners
Step-by-step explanation:
Looking back at past sequences we can see that when we had 8 contestants we had 2 winners 8/4=2 and we also saw 16/4=4 so that was the formula now we just had to do it on 120 contestants and now we get 30 winners....Hope this helps! :)
Answer:
Step-by-step explanation:
The ratio of contestants to winners is 4 : 1 so to find the number of winners you must divide by 4, so you must divide 120 by 4, which is 30.
