Raina runs 3 miles in 25 minutes. At the same rate, how many miles would she run in 20 minutes?
Answer:
2.4miles
Step-by-step explanation:
3/25 = x/20
60/25=x=2.4miles
Set up a ratio:
3/25 = x/20
Cross multiply:
3x 20 = 25x
60 = 25x
Divide both sides by 25
X = 2.4 miles

The volume of the crayon given it's dimensions is 4,647.9 mm³
The surface area of the crayon is 2,388.9 mm².
What is the volume and surface area of the crayon?Cylinder:
r = d/2
= 8.5 mm/2
= 4.25 mm
h = 80 mm
Cone
r = d/2
= 6.5 mm/2
= 3.25 mm
h = 10 mm
Volume of a cylinder = πr²h
= 3.14 × 4.25² × 80
= 3.14 × 18.0625 × 80
= 4,537.3 mm³
Volume of a cone = 1/3πr²h
= 1/3 × 3.14 × 3.25² × 10
= 1/3 × 3.14 × 10.5625 × 10
= 331.6625/3
= 110.5541666666666
Approximately,
110.6 mm³
Volume of the crayon = Volume of a cylinder + Volume of a cone
= 4,537.3 mm³ + 110.6 mm³
= 4,647.9 mm³
Surface area of a cone = πr (r + √h² + r²)
= 3.14 × 3.25(3.25 + √10² + 3.25²)
= 3.14 × 3.25(3.25 + √100 + 10.5625)
= 3.14 × 3.25 (3.25 + √110.5625)
= 3.14 × 3.25(3.25 + 10.5)
= 3.14 × 3.25(13.75)
= 3.14 × 44.6875
= 140.3 mm²
Surface area of a cylinder = 2πrh + 2πr²
= 2×3.14×4.25×80 + 2×3.14×4.25²
= 2,135.2 + 113.4325
= 2,248.6 mm²
Surface area of the crayon = Surface area of a cone + Surface area of a cylinder
= 140.3 mm² + 2,248.6 mm²
= 2,388.9 mm²
Hence, 2,388.9 mm² and 4,647.9 mm³ is the surface area and volume of the cone.

Write the equation for an absolute value function with the following transformations:
translate left 9 units, stretch by a factor of 5, and translate down 23 units
Answer:
j(x) = 5 |x+9|-23
Step-by-step explanation:
f(x) = |x|
translate left 9 units
y = f(x + C) C > 0 moves it left
g(x) = |x+9|
translate down 23 units
y = f(x) + C C < 0 moves it down
h(x)= |x+9|-23
stretch by a factor of 5
y = Cf(x) C > 1 stretches it in the y-direction
j(x) = 5 |x+9|-23

given that f(x)=x^2-5x+6 evaluate the function
The function f(x) = x^2-5x+6 can be evaluated at any value of x by substituting the value into the function and simplifying the expression. We can also graph the function to see what it looks like.
To evaluate the function, we need to substitute a value for x and simplify the expression. We can evaluate the function f(x) = x^2-5x+6 by following these steps:
Step 1: Given that f(x)=x^2-5x+6
Step 2: Substitute a value for x into the function. Let's say x = 2. We will evaluate f(2).f(2) = 2^2 - 5(2) + 6f(2) = 4 - 10 + 6f(2) = 0Step 3: The value of the function at x = 2 is 0.
Therefore, f(2) = 0.We can evaluate the function at any value of x by following the same steps.
The key is to substitute the value for x into the function and simplify the expression. For example, if we wanted to evaluate the function at x = 1, we would follow these steps:f(1) = 1^2 - 5(1) + 6f(1) = 1 - 5 + 6f(1) = 2
Therefore, f(1) = 2.We can also graph the function to see what it looks like. The graph of f(x) = x^2-5x+6 is a parabola that opens upward. The vertex of the parabola is located at the point (2.5, -1.25).
The x-intercepts of the parabola are located at the points (2, 0) and (3, 0). The y-intercept of the parabola is located at the point (0, 6). The graph of the function is shown below:
Overall, the function f(x) = x^2-5x+6 can be evaluated at any value of x by substituting the value into the function and simplifying the expression. We can also graph the function to see what it looks like.

Use zero- through third-order Taylor series expansions to predict f(2, 7) for f(x) = cos(3x) using a base point of x_0 = 2.5. For each approximation, list the following:
a. Approximate value of f(2, 7)
b. On what order of the step size h is the truncation error?
c. Compute the true percent relative errors, epsilon_t, for each approximation.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Given:
[tex]\bold{f(x) = cos(3x)}\\\to f'(x) = - 3 sin (3x)\\\to f''(x) = - 9 cos (3x)\\\to f'''(x) = 27 sin (3x)\\[/tex]
Similarly:
[tex]\bold{f(2.5)' = cos(6.75)}\\\to f'(2.5) = - 3 sin (6.75)\\\to f''(2.5) = - 9 cos (6.75)\\\to f'''(2.5) = 27 sin (2.5)\\[/tex]
calculating the order values [tex]\longrightarrow \cos(6.75)[/tex]:
In the 1st order:
[tex]\to cos(6.75) + (x-2.5) 3 sin (6.75)[/tex]
In the 2nd order:
[tex]\to cos(6.75) + [1- \frac{(x-2.5)^2}{2}9] + (x-2.5) 3 sin (6.75)[/tex]
In the 3rd order:
