Calculate the average rate of change over the interval from x=1 to x=3
-2
6
8
12
Answer:
The average rate of change over the given interval is 12
Step-by-step explanation:
Here, we want to calculate the average rate of change over the given interval
Mathematically, we can calculate the average rate of change using the formula below;
f(b) - f(a)/b-a
The f values are same as the y values
Thus, we have it that;
a = 1 and b = 3
f(a) = -5 and f(b) = 19
The average rate of change is thus;
(19-(-5))/(3-1) = 24/2 = 12
The density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. Express this density in pounds per pint. Round your answer to the nearest hundredth.
Answer:
1.641× 10^-3 pounds/ cubic inch
Step-by-step explanation:
Density= mass / volume
Mass of the material= 9 kilograms
Volume= 7 cubic feet
Density= 9/7= 1.286 kg/ ft^3
Density= 1.286 kg/ ft^3
To Convert to pounds per inch
1 kg/ ft^3 = 0.00128 pound / cubic inch
1.286 kg/ ft^3 = X pounds/ cubic inch
X=( 1.286 × 0.00128)
= 0.0016407087 pounds/ cubic inch
= 1.641× 10^-3 pounds/ cubic inch
Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch

8 Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.
A (-4,-3)
B (-4,3)
C (4, -3)
D (3, 4)
Answer: D (3,4) trust and believe
brainlyst pls I think I spelt is wrong
Step-by-step explanation:
When a line or shape or point is rotated, it must be rotated around a point.
The image of the point is D. (3,4)
The point is given as:
[tex]\mathbf{(x,y) = (-3,-4)}[/tex]
A 180-degree rotation across the origin is represented as:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Substitute values for the coordinates of the point (x,y)
[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]
Simplify
[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]
Hence, the image of the point is D. (3,4)

Answer:
f(x)=x+2
Step-by-step explanation:
Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be 3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.

i think this is algebra
Step-by-step explanation:
The first thing you have to do is open the multiplication parenthesis to substitute V for 2
5v + 3
5 (2) + 3
Now that you have the parenthesis, you multiply and then the result that you add.
5(2) or 5x2= 10 but is better with parenthesis.
10 + 3

sooo what can we set equal
note the lines have the same lenght, therefore the arc length will also be the same, then they give us the other two lengths to make the entire circle , yay
so then just set all the arc lengths equal to 360 °
(3x+ 30) + (3x + 30 ) + 2x + 4x = 360 ( put like terms together )
12x + 60 = 360 ( subtract 60 from both sides )
12x = 300 ( divide both side by 12 )
x = 25
nice we now know X :)
