The sum of three consecutive numbers is 72 what is the smallest of the numbers
Answer:
23
Step-by-step explanation:
Suppose,
the first number = x
the second number = x+1
the third number = x+1+1 = x+2
Question wise,
x+x+1+x+2 = 72
3x+3 = 72
3x = 72-3 = 69
x = 69/3 = 23
so the numbers are,
23,(23+1)=24 and (23+2)=25

Answer:
[tex]T_n=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]
Step-by-step explanation:
nth term of an A.P. is given by the explicit formula,
[tex]T_n=a+(n-1)d[/tex]
Here, 'a' = First term
n = number of term
d = common difference
For an A.P. given as,
[tex]\text{log}_a(54),\text{log}_a(18),\text{log}_a(6),....[/tex]
First term 'a' of the given A.P. = [tex]\text{log}_a(54),[/tex]
Common difference 'd' = [tex]T_2-T_1[/tex]
= [tex]\text{log}_a(18)-\text{log}_a(54)[/tex]
= [tex]\text{log}_a(\frac{18}{54})[/tex]
= [tex]\text{log}_a(\frac{1}{3})[/tex]
= [tex]-\text{log}_a(3)[/tex]
[tex]T_n=\text{log}_a(54)+(n-1)[-\text{log}_a(3)][/tex]
[tex]=\text{log}_a(54)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3\times 2)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)+\text{log}_a(3)[/tex]
[tex]=4\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)[/tex]
[tex]=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]

Which statement describes the graph of function g?
f(x) = 2x
g(x) = 2x + 3
The graph of g is 3 units to the left of the graph of f.
The graph of g is 3 units below the graph of f.
The graph of g is 3 units above the graph of f.
The graph of g is 3 units to the right of the graph of f.
9514 1404 393
Answer:
The graph of g is 3 units above the graph of f.
Step-by-step explanation:
Adding 3 to each y-value shifts the graph up 3 units.
__
In the case of the straight line given here, it also has the appearance of shifting the graph left. The left-shift, however, is not 3 units. The amount of apparent horizontal shift will depend on the slope of the original line.

If x and y are positive integers is x - y always positive explain
Note that x and y are nonzero integers. It means that x and y will always have same sign (both are either positive or negative, since they are nonzero). Hence, xy term is always positive.
Answer:
No, if y happens to be a larger integer than x, then the result will be negative.
Step-by-step explanation:
For example, lets say that x=4 and y=9, so x-y = 4-9 = -5.
But if we were to reverse it and make x=9 and y=4, then x-y = 9-4 = 5.
Suppose that a new employee starts working at $7.72 per hour and receives a 4% raise each year. After time t, in years, his hourly wage is given by the equation y=$7.72(1.04)t. Find the amount of time after which he will be earning $10.00 per hour.
Answer:
6.5978 years
Step-by-step explanation:
y=7.72(1.04)^t
10=7.72(1.04)^t
1.04^t=1.2953367875647668
log 1.04^t=log 1.2953367875647668

It has the same slope and the same y-intercept.
It has the same slope and a different y-intercept.
It has the same y-intercept and a different slope.
It has a different slope and a different y-intercept
Answer:
The correct option is;
It has the same slope and a different y-intercept
Step-by-step explanation:
The data on the table can be presented as follows;
x [tex]{}[/tex] y
-2/3 [tex]{}[/tex] -3/4
-1/6 [tex]{}[/tex] -9/16
1/3 [tex]{}[/tex] -3/8
5/6 [tex]{}[/tex] -3/16
The rate of change of the function, m = (-3/16 - (-3/4))/(5/6 - (-2/3)) = 3/8
The equation of the line given by the data points in point and slope form is given as follows;
y - (-3/16) = 3/8×(x - 5/6)
y = 3·x/8 - 5/16 - 3/16 = 3·x/8 - 1/2
y = 3·x/8 - 1/2
The y intercept is given at when x = 0, therefore, at the y-intercept, y = 3 × 0/8 - 1/2 = -1/2
The y-intercept is (0, -1/2)
The x-intercept occurs at y = 0, therefore, at the x-intercept, we have;
0 = 3·x/8 - 1/2
∴ 3·x/8 = 1/2
x = 4/3
Therefore, the x-intercept is 4/3 and the coordinates of the x-intercept is (4/3, 0)
Given that the x-intercept is different, the y-intercept of the two lines with the same slope are also different
The correct option is therefore that it has the same slope and a different y-intercept;

what is the area of a shaded region in the quarter circle
radius 12
Answer:
I guess that the shaded area is a quarter of a circle of radius 12 units.
Is easy to know that the area, will be equal to the quotient between the area of a circle of radius 12, and 4
We know that the area of a circle of radius R is:
A = pi*R^2
in this case, R = 12
pi = 3.14
Then:
A = 3.14*12^2 = 452.16
And a fourth of that is:
A/4 = (452.16)/4 = 113.04
The area of the shaded region is 113.04 square units

write a function G whose graph represents the indicated transformation of the graph f
[tex]f(x) = \frac{2}{3} {x}^{2} + 2[/tex]
vertical stretch by a factor of 3
Answer:
[tex]G(x) = 2x^2+6[/tex].
Step-by-step explanation:
The given function is
[tex]f(x) = \frac 2 3 x^2 +2[/tex]
On vertical stretch by a factor of 3, the new function G(x) is
G(x) = 3 f(x)
So, [tex]G(x) = 3 \times ( \frac 2 3 x^2 +2)= 2x^2+6[/tex]
Hence, the required function is [tex]G(x) = 2x^2+6[/tex].
the mean of a,b,c,and d is 9 and the mean of a,b,c,d,e and f is 12. find the mean of e and f
Answer:
mean of e + f = 18
Step-by-step explanation:
(a + b + c + d)/4 = 9 Multiply by 4
a + b + c + d = 9 * 4 = 36
(a + b + c + d + e + f ) / 6 = 12
but a + b + c + d = 36
(36 + e + f)/6 = 12 Multiply by 6
36 + e + f = 72 Subtract 36 from both sides
e + f = 36 Divide by 2 to find the mean.
(e + f)/2 = 36/2
mean of e + f = 18

Im confusion? Could someone help me out.
Answer:
20cm
Step-by-step explanation:
for the triangle:
Perimeter = 30cm
a + a + a = 30
3a = 30
hence a = 10cm
For the rectangle:
Perimeter = 30cm
a + a + b + b = 30
but a = 10cm
10 + 10 + b + b = 30
20 + 2b = 30
2b = 10
hence b = 5cm
Perimeter of square = b + b + b + b
= 5 + 5 + 5 + 5 = 20cm

A school lunch contains 12 cheese sticks. Seventy-five students buy the lunch. What is the total number of cheese sticks served?
Answer:
900 cheese sticks served (thats a lot of cheese)
Step-by-step explanation:
You can multiply to find how much in total
12*75
you’d get 900
Total number of cheese sticks served in 75 school lunches is 900.
Given that a school lunch contains 12 cheese sticks and 75 students buy the lunch,
we have to find the total number of cheese sticks served.
To find the solution,
We can use a simple multiplication formula that says,
The total number of cheese sticks served equals the number of cheese sticks in one lunch multiplied by the number of lunches served.
Therefore,
we can write,
⇒Total number of cheese sticks served = Number of cheese sticks in one lunch x Number of lunches served
As there are 75 students who buy the lunch,
We can find the number of lunches served by dividing the total number of students by the number of students in one lunch.
Since one lunch contains 12 cheese sticks, we can write,
⇒ Number of lunches served = Total number of students / Number of students in one lunch
⇒ Number of lunches served = 75 / 1
⇒ Number of lunches served = 75
Now that we know the number of lunches served,
we can use the multiplication formula to find the total number of cheese sticks served,
⇒ Total number of cheese sticks served = Number of cheese sticks in one lunch x Number of lunches served
⇒ Total number of cheese sticks served = 12 x 75
⇒ Total number of cheese sticks served = 900
Therefore,
The total number of cheese sticks served in 75 school lunches is 900.

The equation modeling the population growth of a small town is P(t)=30000(1.02)^t, where P represents the population, and t represents the years from now. What is the approximate population change that occurs between 2 years from now and 10 years from now.
Answer:
5358
Step-by-step explanation:
The equation modeling the population growth of a small town is given as:
P(t)=30000(1.02)^t
When t = 2
P(2) = 30000(1.02)^2
P(2) = 31212
When t = 10
P(10) = 30000(1.02)^10
P(10) = 36569.8326
The approximate population change that occurs between 2 years from now and 10 years from now is calculated as:
= P(10) - P(2)
= 36569.83259984272 − 31212
= 5357.8325998
