Determine the value of impulse from this graph of momentum vs time
Answer:
try 12 Newton seconds
Step-by-step explanation:
I think it's going to be 12 because if you find the slope of the first line you get 1 Newton and the slope of the second line is -1 Newton's. so that means there is a change of -2 newtons. so if you multiply -2 Newton's by the 6 seconds you -12 Newton seconds. let me know if this is correct as it's been a while since I've done this type of stuff.
Answer:
The value of impulse is 9 N-s.
Step-by-step explanation:
The momentum vs time graph shows the impulse
Impulse :
Impulse is the product of force and time.
In mathematical terms,
[tex]I= F\Delta t[/tex]
Where, F = force
t = time
According to graph,
Impulse[tex]I = F\cdot t[/tex]=total area
[tex]I=\dfrac{1}{2}\times3\times6[/tex]
[tex]I=9\ N-s[/tex]
Hence, The value of impulse is 9 N-s.

The point-slope form of a lone has a slope of -w and passes through point (-5,2) is shown below.
y+2=-2(x-5)
What is the equation in slope intercept form?
Answer:
y = -2x + 8Step-by-step explanation:
The point-slope form of an equationo f a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
We have
[tex]y+2=-2(x-5)\\\\y-(-2)=-2(x-5)[/tex]
Therefore we have
the slope: m = -2
the point: (5, -2) not (-5, 2)!!!
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
Convert:
[tex]y+2=-2(x-5)[/tex] use the distributive property a(b + c) = ab + ac
[tex]y+2=-2x+10[/tex] subtract 2 from both sides
[tex]y=-2x+8[/tex]

The option B is correct. A rhombus and a rectangle always have opposite sides with equal length in common. This is a defining property of all parallelograms.
In geometry, both a rhombus and a rectangle are types of parallelograms. To determine what characteristics they have in common, we must identify their properties. A rhombus has all sides of equal length, but its angles are not necessarily right angles. In contrast, a rectangle has all angles as right angles, but its sides are not necessarily of equal length. Therefore, the characteristic that both a rhombus and a rectangle always have in common is:
Opposite sides with equal length (Option B)This means that in both a rhombus and a rectangle, the opposite sides are parallel and equal in length, which is a defining property of all parallelograms.
A cat and a dog have a race. The cat’s strides are 30% shorter than the dog’s but it makes 30% more strides than the dog. Which of them will win the race?
Let [tex]x[/tex] be the length of a cat's stride, and [tex]y[/tex] their stride per time unit ratio.
So, in a time unit, the cat will cover a distance of [tex]xy[/tex]
Dogs strides are 30% longer, do a dog's stride is
[tex]\dfrac{130}{100}x = \dfrac{13x}{10}[/tex]
But its stride per time unit is 30% less:
[tex]\dfrac{70}{100}y = \dfrac{7y}{10}[/tex]
So, in a unit of time, the dog will cover a distance of
[tex]\dfrac{13x}{10}\dfrac{7y}{10} = \dfrac{91}{100}xy[/tex]
So, in the same amount of time, the dog covers 91% of the distance of the cat.

what relation describes the graph?
Answer:
C
Step-by-step explanation:
They are written in (x,y) coordinates. so (0,2 1/2) is the dot on the y axis located at 2 1/2 and is directly on the line as x is 0 and y is 2 1/2.
(-1/2,0) coordinate will be on the left of the origin (the centre of the graph a.k.a 0,0) as the x is negative. the y is 0 so it will be on the x axis.
Just remember, if x is negative then the dot moves to the left, if it is positive then to the right. If y is positive then it will move upwards. If it is negative then it will move downwards. Therefore, the x coordinate controls right and left, the y coordinate controls up and down. If it is 0 then it will not move and just stay on that axis.

Answer:
Basically it means to do Keep, Change, Flip. that's a better way to remember "reciprocal". keep the 5, change the ÷ to a × and flip the fraction 2/9 to a 9/2.
After doing that, you'll get the the first answer. 5/1 × 9/2 = 45/2
Answer: First option.
Step-by-step explanation:
When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.
To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.
Then, the reciprocal of the fraction [tex]\frac{2}{9}[/tex] is:
[tex]\frac{9}{2}[/tex]
Therefore, you can find the quotient of [tex]3[/tex]÷[tex]\frac{2}{9}[/tex] by multiplying [tex]\frac{5}{1}[/tex] by [tex]\frac{9}{2}[/tex]:
[tex]5[/tex]÷[tex]\frac{2}{9}=\frac{5}{1}*\frac{9}{2}=\frac{45}{2}[/tex]

Step-by-step explanation:
( 9 x 10²) (2 x [tex]10^{10}[/tex] )
= (9)(2) x [tex]10^{10+2}[/tex]
=18 x [tex]10^{12}[/tex]
= 1.8 x [tex]10^{13}[/tex]
Answer:
(9x10^2)(2x10^10)
= 1.9 x 10^13 (In scientific notation)
Step-by-step explanation:
Expression to be simplified is given as:
(9x10^2)(2x10^10)
= 9x10^2x2x10^10
= 9x2x10^2x10^10
The base here in the expression is same so the power will add up:
= 18 x 10^(2+10)
= 1.8 x 10^12
Using Scientific notation on the expression, we know that the decimal point must after the first digit so that the number let us say x is such that x > 0 and x < 10. To move decimal one place back, we will multiply it with 10^1:
18 x 10^12
= 1.8 x 10 x 10^12
= 1.8 x 10^(1+12)
= 1.8 x 10^13
write the standard equation of a circle that is tangent to the x-axis with the center located at (2,4)
Answer:
Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0
Final answer:
The standard equation of a circle tangent to the x-axis with center (2,4) is (x - 2)² + (y - 4)² = 16.
Explanation:
To write the standard equation of a circle that is tangent to the x-axis with the center located at (2,4), we must recognize that the distance from the center of the circle to the x-axis is equal to the radius of the circle. Since the center is at (2,4), the distance to the x-axis (which is y=0) is 4 units; thus, the radius of the circle is 4.
The standard form of the equation of a circle with center (h,k) and radius r is (x - h)² + (y - k)² = r². Substituting the given center (2,4) and the radius 4 into this formula, we get:
(x - 2)² + (y - 4)² = 4²
Simplifying the radius squared term, we obtain the final equation:
(x - 2)² + (y - 4)² = 16

[tex] \sqrt{ \frac{3}{64} } [/tex]
Answer:
[tex]\sqrt{\frac{3}{64} }[/tex] in simplified form is [tex]\frac{\sqrt{3}}{8}[/tex]
Step-by-step explanation:
We need to solve the expression
[tex]\sqrt{\frac{3}{64} }[/tex]
We know that [tex]\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}[/tex]
and 64 = 8*8
Solving we get
[tex]=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}[/tex]
So [tex]\sqrt{\frac{3}{64} }[/tex] in simplified form is [tex]\frac{\sqrt{3}}{8}[/tex]
To simplify the given radical expression √3/64, first express the fraction as a power of a fraction. Apply the power rule of radicals and simplify the expression.
Explanation:To simplify the given radical expression √3/64, we first express the fraction under the radical sign as a power of a fraction. 3/64 can be written as 3/(26). Next, we can apply the power rule of radicals, which states that √(a/b) = √a/√b. Applying this rule, we can rewrite the radical expression as √3/(26). Finally, we can simplify the expression by evaluating the square root of 3 and 26. The simplified expression is √3/23 or 3/(23).

Which expression gives you the distance between the points (5,1)and(9,-6)
Answer:
[tex]D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]
Step-by-step explanation:
Here we are supposed to find the distance between the two coordinates in a plane. The coordinates given to us are
(5,1) and (9,-6)
We can find the distance using distance formula. The distance formula is given as
[tex]D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]
Where
[tex](x_{2},y_{2}) ; (x_{1},y_{1})[/tex]
are the two coordinates
Hence
[tex]x_{2} = 9 ; y_{2}= -6\\x_{1}=5; y_{1}=1[/tex]
Substituting these values in the distance formula we get
[tex]D=\sqrt{(9-5)^{2} +(-6-1)^{2}}\\D=\sqrt{(4)^{2} +(-7)^{2}}\\D=\sqrt{16+49}\\D=\sqrt{65}\\[/tex]
Hence the Distance is [tex]D=\sqrt{65}\\[/tex]
If 3p-q=6 and 2p+3q=4 find q
Answer:
It is -24/11
Step-by-step explanation:
This is a system of equations. Using substitution should give the answer.
Taking the first equation, q = 3p - 6. Plug this into the second equation.
2p + 3(3p - 6) = 4. Distributing gives 2p+ 9p - 18 = 4. Subtract 4 from both sides to give: 11p - 14 = 0. p = 14/11
Plug this back into the first equation.
42/11 - q = 6
q = 42/11 - 6, which equals -24/11
Hope this helps!
Answer:
Correct Answer: Option A
Explanation
3p - q = 6 ........ 1
2p + 3q = 4 ....... 2
Multiply eqn 1 by 3
9p - 3q = 18 ........ 3
2p - 3q = 4 ......... 2
Add eqn3 and eqn2
11p = 22 => p = 22/11 = 2
Substitute for p =2 in eqn1
3p - q = 6
3x2 - q = 6 => 6 - q = 6 => -q = 6 - 6

B y= -5/8x+ 16
C y= -15/2x- 49
D y= -15/2x+ 71
Answer:
A
Step-by-step explanation:
Recall the general equation for a straight line is
y = mx + b
where m is the gradient and b is the y-intercept
given 2 points whose coordinates are (x1, y1) and (x2, y2), m can be found with the following formula:
m = [tex]\frac{y1-y2}{x1-x2}[/tex]
in this case, x1 = -8, y1 = 11, x2 = 4, y2=7/2
applying these values to the formula for m will give
m = -(5/8)
We can see immediately that the only 2 possible answers are A or B.
If we substitute this back into the general equation, we get:
y = -(5/8)x + b
In order to find the value for b, we substitute any one of the 2 given points back into this equation. Lets choose (-8,11)
11 = -(5/8) (-8) + b
11 = -(5/8) (-8) + b
11 = 5 + b
b = 6
hence A is the answer.
