The United States Capitol is
located at (2, 4) on a coordinate grid. The White
House is located at (-10, 16) on the same coordinate
grid. Find two different points on a segment joining
the United States Capital and the White House such
that the ratio of the two shorter segments created by
each point is 1:3.
Answer:
The two different point on a segment joining the United States Capital and the White House such that the ratio of the shorter segments created by each is 1 : 3 are [tex]\vec C_{1} =(-1,7)[/tex] and [tex]\vec C_{2} = (-7,13)[/tex].
Step-by-step explanation:
At first we need to calculate the vector distance between [tex]A(x,y) = (2, 4)[/tex] and [tex]B(x,y) =(-10,16)[/tex] by following vectorial subtraction:
[tex]\overrightarrow{AB} = \vec B - \vec A[/tex] (Eq. 1)
Where:
[tex]\overrightarrow{AB}[/tex] - Vector distance between points A and B, dimensionless.
[tex]\vec A[/tex], [tex]\vec B[/tex] - Vector distance between each point and origin, dimensionless.
If we know that [tex]A(x,y) = (2, 4)[/tex] and [tex]B(x,y) =(-10,16)[/tex], then we have the following result:
[tex]\overrightarrow {AB} = (-10,16)-(2,4)[/tex]
[tex]\overrightarrow{AB} = (-10-2,16-4)[/tex]
[tex]\overrightarrow{AB} = (-12,12)[/tex]
Besides, we can find the location of any point inside the line segment by using the following vectorial equation:
[tex]\vec C = \vec A + r\cdot \overrightarrow{AB}[/tex] (Eq. 2)
Where:
[tex]r[/tex] - Segment factor, dimensionless.
[tex]\vec C[/tex] - Location of resulting point, dimensionless.
There are two different options for the location of resulting point: [tex]r_{1} = \frac{1}{4}[/tex] and [tex]r_{2} = \frac{3}{4}[/tex]. Now we proceed to find each option:
[tex]r_{1} = \frac{1}{4}[/tex]
[tex]\vec C_{1} = (2,4) +\frac{1}{4}\cdot (-12,12)[/tex]
[tex]\vec C_{1} = (2,4)+(-3,3)[/tex]
[tex]\vec C_{1} =(-1,7)[/tex]
[tex]r_{2} = \frac{3}{4}[/tex]
[tex]\vec C_{2} = (2,4) +\frac{3}{4}\cdot (-12,12)[/tex]
[tex]\vec C_{2} = (2,4) +(-9,9)[/tex]
[tex]\vec C_{2} = (-7,13)[/tex]
The two different point on a segment joining the United States Capital and the White House such that the ratio of the shorter segments created by each is 1 : 3 are [tex]\vec C_{1} =(-1,7)[/tex] and [tex]\vec C_{2} = (-7,13)[/tex].

What is the measure of angle q°?
70°
110°
90°
180°
Answer:
sorry but where are the angles
The value of q in the quadrilateral 70°
Given that a quadrilateral we need to find the value of q,
Since we can see that the opposite angles are equal so the quadrilateral can be a parallelogram,
Therefore, we get, q and 110° is consecutive angles and the consecutive angles in a parallelogram are supplementary angles,
So,
110° + q° = 180°
Solve for q,
q° = 180° - 110°
Simplification
q° = 70°
Hence the value of q is 70.

Answer:
26. 1/2
27. 1/4
28. 25
29. 20
Answer:
26) 50% or 1/2 27) 25% or 1/4 28) 25 times 29) 20 times
Step-by-step explanation:
26) A is divided in half of the pie graph, where B and C make up the other half, but you are only concerned about A, so it is half of 100%. 100% / 2 = 50%
27) B and C make up the other half of the pie chart. B is half of the half, so that means (1/2) / 2 or (1/2)*(1/2) which equals 1/4. 1/4 times 100 = 25%.
28) From question 26, you are expected to land on A 50% of the time. So 50% of 50 times is equal to 25 times. 50% of something is equal to 1/2 of something, so you divide 50/2 or multiply 50 * (1/2)
29) From question 27 B and C make up the other half of the pie chart. If B is 1/2 of 1/2, so is C, meaning that you have an equal chance of landing C as you have a chance of landing on B - 25% or 1/4. If you spin 300 times, you calculate 25% or 1/4 of 300. To do that you either multiply 300* (1/4) or do 300 / 4.

A field goal kicker lines up to kick a 44 yard (40m) field goal. He kicks it with an initial velocity of 22m/s at an angle of 55∘. The field goal posts are 3 meters high.Does he make the field goal?What is the ball's velocity and direction of motion just as it reaches the field goal post
Answer:
The ball makes the field goal.
The magnitude of the velocity of the ball is approximately 18.166 meters per second.
The direction of motion is -45.999º or 314.001º.
Step-by-step explanation:
According to the statement of the problem, we notice that ball experiments a parabolic motion, which is a combination of horizontal motion at constant velocity and vertical uniform accelerated motion, whose equations of motion are described below:
[tex]x = x_{o}+v_{o}\cdot t\cdot \cos \theta[/tex] (Eq. 1)
[tex]y = y_{o} + v_{o}\cdot t \cdot \sin \theta +\frac{1}{2}\cdot g\cdot t^{2}[/tex] (Eq. 2)
Where:
[tex]x_{o}[/tex], [tex]y_{o}[/tex] - Coordinates of the initial position of the ball, measured in meters.
[tex]x[/tex], [tex]y[/tex] - Coordinates of the final position of the ball, measured in meters.
[tex]\theta[/tex] - Angle of elevation, measured in sexagesimal degrees.
[tex]v_{o}[/tex] - Initial speed of the ball, measured in meters per square second.
[tex]t[/tex] - Time, measured in seconds.
If we know that [tex]x_{o} = 0\,m[/tex], [tex]y_{o} = 0\,m[/tex], [tex]v_{o} = 22\,\frac{m}{s}[/tex], [tex]\theta = 55^{\circ}[/tex], [tex]g = -9.807\,\frac{m}{s}[/tex] and [tex]x = 40\,m[/tex], the following system of equations is constructed:
[tex]40 = 12.618\cdot t[/tex] (Eq. 1b)
[tex]y = 18.021\cdot t -4.904\cdot t^{2}[/tex] (Eq. 2b)
From (Eq. 1b):
[tex]t = 3.170\,s[/tex]
And from (Eq. 2b):
[tex]y = 7.847\,m[/tex]
Therefore, the ball makes the field goal.
In addition, we can calculate the components of the velocity of the ball when it reaches the field goal post by means of these kinematic equations:
[tex]v_{x} = v_{o}\cdot \cos \theta[/tex] (Eq. 3)
[tex]v_{y} = v_{o}\cdot \cos \theta + g\cdot t[/tex] (Eq. 4)
Where:
[tex]v_{x}[/tex] - Final horizontal velocity, measured in meters per second.
[tex]v_{y}[/tex] - Final vertical velocity, measured in meters per second.
If we know that [tex]v_{o} = 22\,\frac{m}{s}[/tex], [tex]\theta = 55^{\circ}[/tex], [tex]g = -9.807\,\frac{m}{s}[/tex] and [tex]t = 3.170\,s[/tex], then the values of the velocity components are:
[tex]v_{x} = \left(22\,\frac{m}{s} \right)\cdot \cos 55^{\circ}[/tex]
[tex]v_{x} = 12.619\,\frac{m}{s}[/tex]
[tex]v_{y} = \left(22\,\frac{m}{s} \right)\cdot \sin 55^{\circ} +\left(-9.807\,\frac{m}{s^{2}} \right)\cdot (3.170\,s)[/tex]
[tex]v_{y} = -13.067\,\frac{m}{s}[/tex]
The magnitude of the final velocity of the ball is determined by Pythagorean Theorem:
[tex]v =\sqrt{v_{x}^{2}+v_{y}^{2}}[/tex] (Eq. 5)
Where [tex]v[/tex] is the magnitude of the final velocity of the ball.
If we know that [tex]v_{x} = 12.619\,\frac{m}{s}[/tex] and [tex]v_{y} = -13.067\,\frac{m}{s}[/tex], then:
[tex]v = \sqrt{\left(12.619\,\frac{m}{s} \right)^{2}+\left(-13.067\,\frac{m}{s}\right)^{2} }[/tex]
[tex]v \approx 18.166\,\frac{m}{s}[/tex]
The magnitude of the velocity of the ball is approximately 18.166 meters per second.
The direction of the final velocity is given by this trigonometrical relation:
[tex]\theta = \tan^{-1}\left(\frac{v_{y}}{v_{x}} \right)[/tex] (Eq. 6)
Where [tex]\theta[/tex] is the angle of the final velocity, measured in sexagesimal degrees.
If we know that [tex]v_{x} = 12.619\,\frac{m}{s}[/tex] and [tex]v_{y} = -13.067\,\frac{m}{s}[/tex], the direction of the ball is:
[tex]\theta = \tan^{-1}\left(\frac{-13.067\,\frac{m}{s} }{12.619\,\frac{m}{s} } \right)[/tex]
[tex]\theta = -45.999^{\circ} = 314.001^{\circ}[/tex]
The direction of motion is -45.999º or 314.001º.

The wavelength of violet light is 4.0 x 10^−7 m. The wavelength of red light is 6.5 x 10^−7 m. How much longer is the wavelength of red than violet?
A 2.5 × 10^–7 m
B 1.05 × 10^–7 m
C 2.5 × 10^–6 m
D 1.05 × 10^–6 m
Answer:
A 2.5 × 10^–7 m
Step-by-step explanation:
Given
wavelength of violet light = 4.0 x 10^−7 m.
The wavelength of red light = 6.5 x 10^−7 m
To find the how much longer is wavelength of red light than violet light we have to find difference of wavelength of red and violet light
Difference in wavelength of red light and violet light =
wavelength of red light -wavelength of violet light
= 6.5 x 10^−7 m - 4.0 x 10^−7 m
Difference in wavelength of red light and violet light = (6.5 - 4.0)*10^−7 m
Difference in wavelength of red light and violet light =2.5 x 10^−7 m
Thus,
wavelength of red light is 2.5 x 10^−7 m longer than wavelength of violet light

Mary and her family ordered a large pizza for dinner. Half of the pizza is plain and half of the
pizza has pepperoni. Mary loves pepperoni so she ate 1/5 of the full pizza (all of which had pepperoni). How much of the remaining full pizza has pepperoni?
Answer:
1.5/5 or 1 1/2/5
B: 3/10
Step-by-step explanation:
2.5/5 is the whole part of pizza with pepperoni. So 1/5 subtracted from 2/5/5 is 1.5 The remaining part of the pizza with pepperoni is 1.5/5!
1.5/5 is 0.3
3/10=0.3!
A survey of 100 people found that 35 people exercise in the morning,45 people exercise in the afternoon,and 20 people exercise at night. Tara claims that 35:55,45:80,and 20:65 are possible ratios from this date. Jim claims that 35:100,45:100,and 20:100 are possible ratios from this date. Who is correct? Explain
Answer:
Jim is correct
Step-by-step explanation:
A survey of 100 people found that 35 people exercise in the morning,45 people exercise in the afternoon,and 20 people exercise at night.
People who exercise in the morning = 35
= 35/100 = 7/20
Hence, the ratio is 35:100
People who exercise in the afternoon = 45 = 45/100 = 9/20
the ratio is 45:100
People who exercise at night = 20
= 20/100 = 1/5
= The ratio is 20:100
The possible ratios from this date are : 35:100,45:100,and 20:100

Can someone help me with the equation below??
Answer:
The answer is number two o x< -2 or x > 5
Answer:
x<-2 or x>5 (the second choice)
Step-by-step explanation:
This is an "or" inequality. Both of the circles on the number line are open, so the signs we will use are going to be either < or >.
The shaded line on the left means x is less than -2 (x<-2). The shaded line on the right means x is greater than 5 (x>5).
If we write this as an "or" inequality, it will be...
x<-2 or x>5
In case you didn't know, if this was an "and" inequality, the shaded lines would intercept. But in this case, the shaded parts went opposite ways, so this is most likely an "or" inequality.
