Answers
Answer:
y = 40(1.5)ˣAbout 304 visitorsStep-by-step explanation:
Formula for exponential function:
y = abˣUse two points from the graph to determine the function:
(0, 40) and (1, 60)Substitute the coordinates and work out the values of a and b:
40 = ab⁰ ⇒ 40 = a60 = ab¹ ⇒ 60 = ab ⇒ 60 = 40b ⇒ b = 60/40 ⇒ b = 1.5The function is:

y is inversely proportional to V1+x.
When x=8, y = 2.
Find y when x = 15.
Please help me with this real quick!
Answers
Answer:
y = 1.5
Step-by-step explanation:
Given y is inversely proportional to [tex]\sqrt{1+x}[/tex] , then the equation relating them is
y = [tex]\frac{k}{\sqrt{1+x} }[/tex] ← k is the constant of variation
To find k use the condition when x = 8, y = 2 , then
2 = [tex]\frac{k}{\sqrt{1+8} }[/tex] = [tex]\frac{k}{\sqrt{9} }[/tex] = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
6 = k
y = [tex]\frac{6}{\sqrt{1+x} }[/tex] ← equation of variation
When x = 15, then
y = [tex]\frac{6}{\sqrt{1+15} }[/tex] = [tex]\frac{6}{\sqrt{16} }[/tex] = [tex]\frac{6}{4}[/tex] = 1.5

On a certain hot summers day 284 people use the public swimming pool the daily prices are $1.50 for children and two dollars for adults their seats for admission total of $467 how many children and how many adult swim at the public pool that day
Answers
Answer:
c = 202 children use the pool, and 284 - 202, or 82 adults.
Step-by-step explanation:
Represent the number of children by c and the number of adults by a.
There are a total of 284 people using the pool, so c + a = 284.
Admission fees are $1.50/child and $2.00/adult. $1.50c is the amount taken in through ticket sales for c children; $2.00a for adults.
Then total ticket sales are ($1.50/child)c + ($2.00/adult)a = $467.
Going back to c + a = 284, a = 284 - c, and so the above equation becomes
($1.50/child)c + ($2.00/adult)(284 - c) = $467
After simplifying this equation in c, we get:
1.50c + 568 - 2c = 467, or
101 = 0.5c. Thus, c = 202 children use the pool, and 284 - 202, or 82 adults.

Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (3, 2 ) and r = 1 , then
(x - 3)² + (y - 2)² = 1² , that is
(x - 3)² + (y - 2)² = 1 → B

Step-by-step explanation:
this is because if a=how much money deposited after t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.
tell me if this is incorrect.
Answer:
25
Step-by-step explanation:
In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.

14y-8=13 plssss helpp
Answers
14y-8=13
We add 8 on both sides to cancel it out and add it to 13.
14y-8=13
+8 +8
14y=21
Now we divide 14 on both sides to cancel it out, separate it from the y, and to divide it from 21.
14y=21
/14 /14
y=1.5

hope it helps
Answer:
Add 8 to both sides of the equation to get 14y=21
Divide both sides of the equation by 14 to get y= 1.5

Find the value of x.
Answers
Answer:
45 degrees
Step-by-step explanation:
Before we start, it is important to know that the sum of all angles of a triangle adds up to 180. Since one of the angle measure is already given to us, 90, we can subtract this from 180.
180-90=90
This tells us that the two remaining angles will add together to equal 90. In addition, it also tells us that the two remaining angles are equal. This means we can divide 90 by 2, and it leaves us that x= 45 degrees.
You can see that this is a right triangle so one of the angles equals 90°. 180-90= 90°.
Now we can see the remaining two angles add up to 2x. So if we put all our work together 2x= 45°.
Divide both sides by 2 to get x alone
And we come to that x equals 22.5.
x= 22.5°

The sum of 3 consecutive odd numbers is 183 ?
Answers
Answer:
The answer is 61.
Step-by-step explanation:
Let, the numbers are: x, (x+2), (x+4)
Now, x+x+2+x+4 = 183
3x + 6 = 183
3x = 177
x = 59
So, second number would be: (x+2) = (59+2) = 61
Answer:
Step-by-step explanation:
n+(n+2)+(n+4)=183
3n+6=183
3n=177
n=59
So the three numbers are 59, 61, and 63.

After that, do pi * r^2. This will be pi*4. You'll get 12.6.
After multiplying 12*4, 48, you add 12.6 and 48, and get 60.6
