The range of the function is {0.16, 0.4, 1, 2.5, 6.25}. With an increase in the value of the domain, the range of the function is increasing.
What is a function?
A function from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.
The given function is
f(x) = 2.5^x.
Given domain is {-2, -1, 0, 1, 2}.
Now putting x = -2, -1, 0, 1, 2 in the function f(x) = 2.5^x.
When x = -2:
f(-2) = 2.5^(-2)
f(-2) = 0.16.
When x = -1:
f(-1) = 2.5^(-1)
f(-1) = 0.4
When x = 0:
f(0) = 2.5^(0)
f(0) = 1.
When x = 1:
f(1) = 2.5^(1)
f(1) = 2.5
When x = 2:
f(2) = 2.5^(2)
f(2) = 6.25
The range of the function is {0.16, 0.4, 1, 2.5, 6.25}
The values of the range increase with the increase of domain.

What is the value of y in the equation y − 7 = 21? (4 points)
Question 1 options:
1) 7
2) 17
3) 21
4) 28
Answer:
4
Step-by-step explanation:
y-7=21
+7 +7
y=21+7
y=28
Answer:
4) 28
Step-by-step explanation:
Isolate the y
add 7 to both sides
y - 7 = 21
y - 7 (+7) = 21 (+7)
y = 21 + 7
y = 28
28 is your answer

4+(3.7-x)=1.72
Answer:
x = 5.98
Explanation:
1. 4+(3.7−)=1.72
2. 4+(−+3.7)=1.72
3. 4−+3.7=1.72
4. 7.7−=1.72
5. −+7.7=1.72
6. −+7.7−7.7=1.72−7.7
7. −=−5.98
Then simplify to x =5.98
Find the missing side length. Round to the nearest tenth.
Can someone PLEASE HELP!!
Answer:
the answer is 17.0 or just 17
Step-by-step explanation:
you have to use the pythagorean theorem, a^2 + b^2 = c^2
a = 11 and b = 13
11^2 + 13^2 = c^2
121 + 169 = c^2
290 = c^2
square root each side, so you have to find the square root of 290 which is 17.0293864
round it to the nearest tenth which is 17.0 but you can just write 17
hope this helps you understand it and answer it :)
Answer:
[tex]\boxed {\boxed {\sf c \approx 17.0}}[/tex]
Step-by-step explanation:
This is a right triangle because of the small square in the corner. Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
In this triangle, 11 and 13 are the legs because they make up the right angle. The missing side is the hypotenuse because it is opposite the right angle.
[tex]a=11\\b= 13[/tex]
[tex](11)^2+(13)^2=c^2[/tex]
Solve the exponents.
11²= 11*11=12113²= 13*13=169[tex]121+169=c^2[/tex]
Add.
[tex]289=c^2[/tex]
We are trying to solve for c, so we must isolate the variable. It is being squared. The inverse of a square is the square root, so take the square root of both sides.
[tex]\sqrt {289}= \sqrt {c^2}[/tex]
[tex]17.0293864=c[/tex]
Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 0 in the tenth place.
[tex]17.0 \approx c[/tex]
The missing side is approximately 17.0
is this a function? why or why not ?
The 59th and 4th team of an Ap are - 61 and 64 respectively. Show that the common differences is - 2.5 and 23rd term is 16.5
Answer:
See answers below
Step-by-step explanation:
T59 = a+58d = -61
T4 = a+3d = 64.
Subtract
58d-3d = -61-64
-55d = -125
d =125/55
d = 25/11
Get a;
From 2
a+3d = 64
a+3(25/11) = 64
a = 64-75/11
a = 704-75/11
a = 629/11
T23 = a+22d
T23 = 629/11+22(25/11)
T23 = 1179/11

Since 5 stickers are in every sheet depending on the number of sheets you get and times it with 5 you get the number of stickers Tara bought.
A random sample of 663 teens who said they did not typically eat fast food reported an average daily calorie intake of 2258, with standard deviation 1519. A random sample of 413 teens who said they did typically eat fast food reported an average daily calorie intake of 2637, with standard deviation 1138. The two populations are moderately positively skewed. Based on the above description, which of the following conditions are met for conducting a hypothesis test for the equality of two means?
a. Both samples are random
b. Samples are independent of one another
c. Both samples are normal enough given the sample size
d. Two population means need to be the same
Answer:
Option B
Step-by-step explanation:
The sample populations are independent of each other and hence for comparing of mean of two population it is very essential that the two populations independent of each other.
Now here one population set consist of only people who eat fast food and the other set of population consists of people who do not eat fast food.

5>3x+8
subtracting eight from both sides we get
-3>3x
dividing by three on both sides we get
-1>x
or x<-1

Which number is composite?
A. 36
B. 2
C. 19
D. 23
Answer:
A. 36
Step-by-step explanation:
A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 36 can be evenly divided by 1, 2, 3, 4, 6, 9, 12, 18 and 36, with no remainder. Since 36 cannot be divided by just 1 and 36, it is a composite number.

given that the 11th term of arithmetic progression is 43 that the first term is 3 find the 4th term
Answer: 15
Step-by-step explanation:
The 11th term of arithmetic progression is 43. We can use this to get the common difference which will be:
a + (n - 1)d = 43
where,
a = first term = 3
n = nth term = 11
d = common difference = unknown
Therefore, a + (n - 1)d = 43
3 + (11 - 1)d = 43
3 + 10d = 43
10d = 43 - 3
10d = 40
d = 40/10
d = 4
Common difference = 4
Therefore, 4th term will be:
= a + (n - 1)d
= a + (4-1)d
= a + 3d
= 3 + 3(4)
= 3 + 12
= 15
The 4th term is 15
