i = 1/2mr^2 solve for m
Answers
Answer:
m=2i/r^2Step-by-step explanation:
Given
i = 1/2mr^2Solving for m
i = 1/2mr^2 ⇒ Multiply both sides by 22i=mr^2 ⇒ Divide both sides by r^2m=2i/r^2Solve for b.
r = (b-5)m
Answers
Answer:
b=5m+r/m
Step-by-step explanation:
Let's solve for b.
r=(b−5)(m)
Step 1: Flip the equation.
bm−5m=r
Step 2: Add 5m to both sides.
bm−5m+5m=r+5m
bm=5m+r
Step 3: Divide both sides by m.
bm/m=5m+r/m
b=5m+r/m
Answer:
b=5m+r/m
Answer:
See Explanation
Step-by-step explanation:
[tex]r = (b - 5)m \\ \\ \frac{r}{m} = b - 5 \\ \\ \frac{r}{m} + 5 = b \\ \\ \frac{r + 5m}{m} = b \\ \\ \huge \red{ \boxed{b = \frac{r + 5m}{m} }}[/tex]

Maria is putting up a shelf on a wall in her closet. The figure below shows triangle ABC, which
represents a bracket that will be used to support the shelf. What is the length of the wall? *
Answers
Anwer:
14 cm
Step-by-step explanation:
Let's apply the Phytagorean Theorem [tex]a^{2}+b^{2}=c^{2}[/tex]
Since we only have one side and the hypotenuse:
[tex]a^{2}+24^{2}=28^{2}\\a^{2}+576=784\\a^{2}=784-576\\a^{2}= 208\\[/tex]
[tex]a=\sqrt{208}\\a= 14.42\\a= 14 cm[/tex]
The length of the wall is approximately 14.4 units.
What is Pythagoras' theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Maria is putting up a shelf on a wall in her closet.
The figure below shows triangle ABC, which represents a bracket that will be used to support the shelf.
AC = 24, BC = 28 = hypotenuse, AB = wall
Using the Pythagorean theorem, we can solve for the length of AB (the wall):
AB² = BC² - AC²
AB² = 28² - 24²
AB² = 784 - 576
AB² = 208
AB = sqrt(208)
AB ≈ 14.4
Therefore, the length of the wall is approximately 14.4 units.

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Find points on the graph.
Point (1, 1)
Point (-1, -3)
Step 2: Find slope m
Substitute: [tex]m=\frac{-3-1}{-1-1}[/tex]Subtract: [tex]m=\frac{-4}{-2}[/tex]Divide: [tex]m=2[/tex]Step 3: Find y-intercept b
Given: (0, -1) as y-intercept
Step 4: Write linear equation
y = 2x - 1
The equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
The slope-intercept form of a linear equation is given by y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Among the options provided, the equation y = 2x - 1 is already in the slope-intercept form. In this equation, the slope is 2, which means that for every unit increase in x, y increases by 2. The y-intercept is -1, indicating that the line intersects the y-axis at the point (0, -1).
The equations y = -2x - 1, y = 1/2x - 1, and y = 1/2x + 1 are not in slope-intercept form. In the equation y = -2x - 1, the slope is -2 and the y-intercept is -1. In the equation y = 1/2x - 1, the slope is 1/2 and the y-intercept is -1. Lastly, in the equation y = 1/2x + 1, the slope is 1/2 and the y-intercept is 1.
Therefore, the equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
