The statement which is true of the growth rate of the functions over the interval 0 ≤ x ≤ 1 is that: B. The exponential grows at the same rate as the quadratic.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity increases or decreases with respect to another quantity.
Mathematically, the rate of change can be calculated by using this formula;
[tex]Rate = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Rate = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
From the given interval and graph (see attachment), the data point for the exponential function would be as follows:
Point (x₁, x₂) = (0, 1)Point (y₁, y₂) = (1, 2)Next, we would calculate the rate of change of the exponential function over the given interval:
Rate of change = (2 - 1)/(1 - 0)
Rate of change = 1/1
Rate of change = 1.
From the given interval and graph (see attachment), the data point for the quadratic function would be as follows:
Point (x₁, x₂) = (0, 1)Point (y₁, y₂) = (0, 1)Next, we would calculate the rate of change of the quadratic function over the given interval:
Rate of change = (1 - 0)/(1 - 0)
Rate of change = 1/1
Rate of change = 1.

Find the coordinate of the image of B (4, 0) after a reflection over the y-axis.
Answers
We need to know reflection of point about axes to solve the problem. The image of B (4,0) after reflection about y-axis is (-4,0).
Reflection about an axis means finding the point on the graph that is at an equal distance from the axis on the opposite side of the reflecting surface. The reflection can be about an axis or a line or origin. When a point is reflected about the x-axis, the sign of the y-coordinate of the point changes, when a point is reflected about y-axis the sign of the x-coordinate of the point changes and when a point reflects about the origin, the sign of both the coordinates change. Here in the question we need to find the reflection of point B (4,0) about y-axis, the image of point B will be (-4,0).
Therefore the image of point B(4,0) when reflected about y-axis is (-4,0).

a/12 = 30.1/12 i am trying to find a if someone could help me please. :)
Answers
The value of a is 30.1
Divide Fraction Definition
The denominators of fractions must match in order to divide them. The numerators' quotient will be the quotient.
The phrase provided is,
a/12 = 30.1/12
We can directly cut the values if the denominator is the same. Since there is a 12 in the denominator on both the right and left sides in this case, remove 12 from both sides.
Thus, a = 30.1
Likewise, you can act in such manner,
a = (30.1 * 12) / 12
a = 30.1
Here, we take the right side of the left side denominator 12 and cancel 12.
Hence, A has a value of 30.1

Kathy has 68 coins in total. She has 5 more dimes than quarters and 5 times as many nickels than quarters. How many of each coin does she have?
Answers
Kathy has 28 dimes, 33 quarters, and 7 nickels, for a total of 68 coins which was found by solving three simultaneous equations.
What exactly are simultaneous equations?Two or more algebraic equations that share variables, such as x and y, are referred to as simultaneous equations. Because the equations are solved simultaneously, they are referred to as simultaneous equations. Each of these equations could have an infinite number of solutions.Given: Kathy possesses a total of 68 coins. She has 5 more dimes than quarters and 5 times as many nickels as quarters.
Let,
number of of coins of dimes = d
number of coins of quarters = q
number of coins of nickels = n
From the given information, we can form equations as follows:
q = 5 + d
q = 5n
d + q + n = 68
Arranging these equations,
q = 5n
d = 5n - 5
n = q/5
On solving these three equations simultaneously,
we get
d = 28
q = 33
n = 7
Therefore, Kathy has 28 dimes, 33 quarters and 7 nickels which together form 68 coins in total.

Third class 178. 528. 706
Crew class 215 698 913
Total 713 1516 2229
Which of the following interpretations are correct?
(A). If a person survived, it is more likely that the person was in the crew than any other individual class.
(b). Given that a person was in the crew, it was more likely that the person died than survived.
(c). If a person died, it is likely that the person was in the third class or crew.
Answers
Answer:
(A) correct
(B) correct
(C) correct
Step-by-step explanation:
(A) is correct
Total survived = 713
Out of the 713 passengers who survived, the number of crew members = 215, the highest. The ratio of 215/713 is higher than any other ratio. This means 30% of those who survived were crew members. The next higher group of survivors was First Class passengers with a survival rate of 202/713 ≈ 28%
(B) is correct
There were 913 crew members. Out of this, 698 died 215 survived.
So it is more likely that given a person was a crew member, the person died than survived. That comprises 698/913 or 76% of crew members who died with only 24% survival rate
(C) is correct
There were 1516 passengers who died
Out of these, 528 + 698 = 1,226 were either third class or crew members and comprised 1226/1516 or approximately 81 percent of people who died

The values of the expression after each property are as follows:

In this problem, the expression is:

After the distributive property, the expression is represented as follows:
9 x w + 9 x 5 = 9w + 45.
(the outer term 9 multiplies each of the inner terms, of w and 5, and then they are added, due to the plus sign).

how do you solve 94 divided by 33 because when I tried solving it, it didn't make sense.
Answers
it's 2.84
step by step:
Start by setting it up with the divisor 33 on the left side and the dividend 94 on the right side.
The divisor 33 goes into the first digit of the dividend 9, 0 time(s). Therefore, put 0 on top.
Multiply the divisor by the result in the previous step (33 x 0 = 0) and write that answer below the dividend.
Subtract the result in the previous step from the first digit of the dividend (9 - 0 = 9) and write the answer below.
Move down the 2nd digit of the dividend 4
The divisor 33 goes into the bottom number 94, 2 time(s). Therefore, put 2 on top.
Multiply the divisor by the result in the previous step (33 x 2 = 66) and write that answer at the bottom.
Subtract the result in the previous step from the number written above it. (94 - 66 = 28) and write the answer at the bottom.
it's a repeating decimal so make sure to add a line on top of the last to digits to represent that it is repeating.

1. Angle 8 is 86°
2. Angle 9 is 94° and
3. Angle 10 is 86°.
Given that,
There are two lines a and b, Which are parallel lines and a line that cut the parallel lines a and b is transversal t.
The interior angles are 7,8,9 and 10.
The angle 7 and 8 are consecutive angles and angle 7= 94°.
The angle 8 and 10 are alternative angles.
We have to find the angles 8,9 and 10.
We take,
The angle 7 and 8 are consecutive angles and angle 7= 94°.
Consecutive angles condition is Sum of the pair of consecutive angles is equal to 180°.
Now,
∠7+∠8=180°
94°+∠8=180°
∠8=180°-94°
∠8=86°
We got angle 8 as 86°.
Now, we take
The angle 8 and 10 are alternative angles.
Alternative angles condition is The pair of alternative angles are always equal if the two lines are parallel lines.
Now,
∠8=∠10
86°=∠10
∠10=86°
We got angle 10 as 86°.
Then we can say that the angle 7 and 9 are alternative angles.
Then,
∠7=∠9
94°=∠9
∠9=94°
We got angle 9 as 94°.
Therefore, The angle 7 is 94°, ∠8 is 86°, ∠9 is 94° and ∠10 is 86°.

f(n+1)=f(n)-2 if f(1) =10
what is f(3)
Answers
The function f(3) has a value of 6
How to evaluate the function?The definition of the function is given as
f(n + 1) = f(n) - 2
Where
f(1) = 10
We start by substituting 1 for n in the equation f(n + 1) = f(n) - 2
So, we have
f(1 + 1) = f(1) - 2
Evaluate the like terms
So, we have
f(2) = f(1) - 2
Substitute f(1) = 10 in f(2) = f(1) - 2
f(2) = 10 - 2
Evaluate the difference
f(2) = 8
We continue by substituting 2 for n in the equation f(n + 1) = f(n) - 2
So, we have
f(2 + 1) = f(2) - 2
Evaluate the like terms
So, we have
f(3) = f(2) - 2
Substitute f(2) = 8 in f(3) = f(2) - 2
f(3) = 8 - 2
Evaluate the difference
f(3) = 6
Hence, the value of f(3) is 6
