For moving object the force acting on the object varies directly with the object acceleration when a force of 36 in acts on a certain object the acceleration of the object is 6 m/s squared if the force is changed to 24 in what will be the acceleration of the object
Answer:
4m/s²
Step-by-step explanation:
Given that:
Force F is directly proportional to acceleration a
F α a
F = ka
Where k is the constant of proportionality
36 = 6k
Solve for K
36 = 6k
k = 36/6
k = 6
If force = 24 ; acceleration =
24 = ka
k = 6
24 = 6a
a = 24/6
a = 4m/s²
To make an international call, there is a flat fee of $3.15 plus $0.05 for every minute that you talk. If you were charged $5.10 for making an international call, for how many minutes did you talk?
Answer:
39 minutes
Step-by-step explanation:
I used a calculator
Answer:
39 minutes
Step-by-step explanation:
a = 0.05m + 3.15 where a=the total charged, m=the amount of minutes
5.10 = 0.05m + 3.15
1.95 = 0.05m
1.95/0.05 = m
m = 39 minutes
Which sequence of transformations will map figure H onto figure H′?Two congruent hexagons are shown on a coordinate plane; hexagon H quadrant one with vertices at 2 comma 2, 2 comma 6, 6 comma 7, 8 comma 6, 8 comma 2, and 6 comma 1; hexagon H prime with vertices at 2 comma negative 8, 2 comma negative 4, 4 comma negative 3, 8 comma negative 4, 8 comma negative 8, and 4 comma negative 9. Rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across x = −6 Rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6 Rotation of 180° about the origin, translation of (x − 10, y + 2), and reflection across y = −6 Rotation of 180° about the origin, translation of (x − 10, y + 2), and reflection across x = −6
Answer:
Rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6
Step-by-step explanation:
The sequence of transformations that will map figure H onto figure H' is the rotation of 180° about the origin, translation of (x + 10, y − 2), and reflection across y = −6.
Given :
Points of Hexagon H -- (2,2), (2,6), (6,7), (8,6), (8,2), (6,1)
Points of Hexagon H' -- (2,-8), (2,-4), (4,-3), (8,-4), (8,-8), (4,-9)
The following steps can be used to transform the hexagon H into hexagon H':
Step 1 - Translate the hexagon in the positive x-axis direction by a factor of 10.
Step 2 - Translate the graph obtained in the above step by factor 2 in the downward direction.
Step 3 - Now, rotate the graph obtained in the above step 180 degrees about the origin.
Step 4 - Then take the reflection of the graph obtained in the above step about y = -6. The resulting graph shows the graph of Hexagon H'.
Therefore, the correct option is B).

Find the y-intercept of the following function:
[tex]2x - 4y = 9[/tex]
Hi there!
[tex]\large\boxed{0, -\frac{9}{4} }[/tex]
2x - 4y = 9
Begin by isolating the y variable by moving 2x to the right-hand side of the equation. (Subtract 2x from both sides):
2x - 2x - 4y = 9 - 2x
-4y = 9 - 2x
Further isolate by dividing both sides by -4:
-4y / (-4) = (9 - 2x) / (-4)
y = -9/4 - 2x/(-4)
Simplify further:
y = -9/4 + 1/2x
y = 1/2x - 9/4
The "b" value is the y-intercept, therefore:
x = 0 at y = -9/4
Answer:
[tex]\huge\boxed{(0, \frac{-9}{4} )}[/tex]
Step-by-step explanation:
2x - 4y = 9
To find the y-intercept, set the x value in the equation to 0.
Rewrite
2(0) - 4y = 9
Simplify
-4y = 9
Multiply both sides of the equation by -1
4y = 9
Divide both sides of the equation by 4
y = -9/4
y = -4.5
Now that we know the y intercept, we can find the coordinate.
(x, y)
Substitute
(0, [tex]\frac{-9}{4}[/tex])

THE LENGTH AND THE BREADTH OF A RECTANGULAR PARK ARE IN THE RATIO 5 : 2. IF ITS PERIMETER IS 168m, FIND ITS LENGTH AND BREADTH.
(STEP BY STEP PLZ) (HOPE U ENJOY IT)
Answer:
Length = 60m, breadth = 24m
Step-by-step explanation:
Let the length of the park be 5x and the breadth 2x.
5x+5x+2x+2x = 168
14x = 168
x = 168 ÷ 14
x = 12
Length (5x) = 12 × 5
= 60
Breadth (2x) = 12 × 2
= 24
Answer:
Length = 60m, breadth = 24m

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the function be f ( x ) = A
Now , Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero
So , the function which represents the graph will be
f ( x ) = 1 / ( x - 2 )² be equation (1)
And , the graph of the function is given below
