You can count from 34-28 and the numbers you counted (the numbers in between 34-28) is your answer.
Answer:
A generic exponential function can be written as:
f(x) = A*e^(b*x)
Where A and b are real numbers, that we need to find.
We know that the points (3, 6) and (7, 18) are solutions to the equation, then we have that:
A*e^(b*3) = 6
A*e^(b*7) = 18
This is a system of equations, to solve this we can take the quotient between the two equations, so we remove the variable A.
(A*e^(b*7))/(A*e^(b*3)) = 18/6
e^(b*7)/e^(b*3) = 3
e^(b*7 - b*3) = 3
e^(4*b) = 3
Now we can apply the Ln(x) to both sides, because:
Ln(e^y) = y
then:
Ln(e^(4*b)) = Ln(3)
4*b = Ln(3)
b = Ln(3)/4
Then we have:
f(x) = A*e^(Ln(3)/4*x)
And we can use one of the equations to find the value of A. for example:
6 = A*e^(Ln(3)/4*3)
6/e^(Ln(3)/4*3) = 2.632
Then the exponential function is:
f(x) = 2.632*e^(Ln(3)/4*x)
Then we have that:
f(20) = 2.632*e^(Ln(3)/4*20) = 639.576
Rounding to the next integer, we have:
f(20) = 640
Answer:
I believe the correct answer is, 100°.
Step-by-step explanation:
If I am correct, and this is a verticle angle, then <em>x </em>should be equal to 100°, as verticle angles are congruent.

Answer:
first = 65
second = 325
Third = 165
Step-by-step explanation:
Let the first number = x
first: x
second: 5x
Third = x + 100
first + second + third = 555
x + 5x + x + 100 = 555 Combine
7x + 100 = 555 Subtract 100 from both sides
7x + 100 - 100 = 555 - 100
7x = 455 Divide by 7
7x/7 = 455/7
x = 65
Answer:
<h2>9/28</h2>
Step-by-step explanation:
<em><u>2 3/7 - 1 1/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:</u></em>
<em><u>L.C.D = 28</u></em>
<em><u>L.C.D = 2821 - 12/28</u></em>
<em><u>L.C.D = 2821 - 12/28= 9/28</u></em>
<u>It won't be a mixed number because the denominator is bigger than the numerator.</u>
