A grocery store is selling peaches for $0.98 per pound. Is this a function or Not function
Answer:
This is a function. Use y=mx+b equation
Step-by-step explanation:
To find the x and y values, simply plug in 0.98 to m. For every pound of peaches, you pay $0.98. The equation would be y=0.98x, where x is the number of pounds of peaches and y is the total cost.

Your bike has a wheel diameter of 29 inches. You are traveling and your wheels are rotating at 148 revolutions per minute. What is the bicycle speed in miles per hour. (Round your answer to the nearest 1000th)
Answer:
12.77 miles per hour
Step-by-step explanation:
Step 1
Convert the diameter from inches to feet
Your bike has a wheel diameter of 29 inches.
1 inch = 0.0833 feet
29 inches =
29 × 0.0833 feet
= 2.41667 feet
Step 2
Circumference of the tire = πD
= π × 2.41667 feet
= 7.5921927182 feet
Step 3
The number feet traveled per hour is
148 revolutions per minute × 7.5921927182 feet
= 1123.6445223 feet per minute
60 minutes = 1 hour
Hence,
1123.6445223 × 60 =
67418.671337 feet per hour.
Converting from Feet per hour to Miles per hours
1 mile = 5280 feet
= 67418.671337 feet per hour/5280 feet
= 12.768687753 miles per hour
Approximately = 12.769 miles per hour

The table and the graph show the relationship between the edge length, x, of a cube and its surface area, y. Is the relation a function?
Also weirdgamergirl7 if your watching this, ty for the answers <3
Answer:
Yes, the relationship between x and y is a non-linear function.
Step-by-step explanation:
Given the table
Edge Length, x Surface Area, y
1 6
2 24
3 54
4 96
The table values clearly represent a function, because each input value has one and only one output value. i.e. there is no repetition of x values.Also from the table values and the graph, it is clear that the function is not a linear function, because the graph is not a straight line. Also, In a cubic function, the highest power over the x variable(s) is 3. So, it is not a linear function.Hence, we conclude that Yes, the relationship between x and y is a non-linear function.
Therefore, the 'last option' is correct.
Answer:
no it is non- linear

Question:
Identify the function that reflects f(x) = 14x3 − 7x2 + 6 across the y-axis and shifts it 6 units up.
Answer:
h(x) = 14x3 + 7x2 + 12
h(x) = −14x3 − 7x2 + 12
h(x) = −14x3 − 7x2
h(x) = 14x3 − 7x2
Answer: there's no answer, the correct answer is f(x) = -14x3 + 7x2
Step-by-step explanation:
1. f(x) = 14x3 − 7x2 + 6
2. reflection over y-axis : f(x) = -14x3 + 7x2 - 6
3. shift 6 units up : f(x) = -14x3 + 7x2 - 6 + 6
4. f(x) = -14x3 + 7x2
The correct function after reflection across the y-axis and shifts it 6 units up is,
⇒ h (x) = - 14x³ - 7x² + 12
What is Function?A relation between a set of inputs having one output each is called a function.
We have to given that;
The function is,
⇒ f (x) = 14x³ - 7x² + 6
Now, After reflection across the y-axis we get;
⇒ f (x) = f (- x)
⇒ f (-x) = 14 (-x)³ - 7 (-x)² + 6
⇒ f (-x) = - 14x³ - 7x² + 6
And, After shifts it 6 units up, we get;
⇒ f (x) = f (x) + 6
Hence, We get the value of function is,
⇒ h (x) = - 14x³ - 7x² + 6 + 6
⇒ h (x) = - 14x³ - 7x² + 12

The diameter of a circle is 16 meters. What is the angle measure of an arc 6 meters long?
Answer:
42.99° or approx 43°
Step-by-step explanation:
Diameter of circle d = 16 m
Lenght of arc l= 6 m
Let the angle measure of the arc be [tex] \theta [/tex]
By length of arc formula of a circle.
[tex]l = \frac{ \theta}{360 \degree} \times\pi d \\ \\ 6 = \frac{ \theta}{360 \degree} \times 3.14 \times \: 16 \\ \\ \theta = \frac{6 \times 360 \degree}{3.14 \times 16} \\ \\ \theta = \frac{2160\degree}{50.24} \\ \\ \theta = 42.9936306 \degree \\ \\ \theta = 42.99 \degree \approx \: 43 \degree[/tex]

Make & the subject of the
Formula
6x ta=5(x+t)
What is the answer please
Answer:
x = 5t - a
Step-by-step explanation:
The problem deals with making a variable the subject of the formula in the expression.
Given expression:
6x + a = 5(x + t)
We are to make x the subject of the formula in the expression
Solution:
6x + a = 5(x+t)
On the right hand side, expand the parentheses and distribute the term outside;
6x + a = 5x + 5t
Bring the term desired to be the subject to one side by adding (-5x) to both sides;
6x + (-5x) + a = 5x + (-5x) + 5t
x + a = 5t
Now add (-a) to both sides
x + a + (-a) = 5t + (-a)
x = 5t - a

What is the length of the radius of a circle with center (10, -14) that is tangent to the line
x=13?
Answer:
length of radius of a circle = 3
Step-by-step explanation:
a tangent line touches the circle at one point
if the tangent line is at x=13 (vertical line) and the center of the circle is
(x,y) = (10,-14) with its center x at 10; then take the difference to find the radius;
x(tangent line) - x(center of circle) = radius of circle
length of radius of a circle = 13-10 = 3
you can also graph the circle and draw the tangent line to find the radius
The length of the radius of a circle as described in the question is; 14.32
The center of the circle is at; (10, -14)
The line that is tangent to the circle is; x = 13.
The coordinate of a point on the line is therefore; (13, 0)
The length of the radius of the circle can.be obtained from Pythagoras theorem as;
(Radius)² = (13-10)² + (-14-0)²(Radius)² = (3)² + (-14)²(Radius)² = 9 + 196Radius = √205Radius = 14.32Read more:

If 2 (3t - 10) + t = 40 + 4t, what is the value of 3t?
Answer:
3t = 60
Step-by-step explanation:
2(3t - 10) = 40 + 3t
6t - 20 = 40 + 3t
3t - 20 = 40
3t = 60
If you need to simplify that then the answer would be t = 20.
