Drag each value to the correct location on the equation. Each value can be used more than once, but not all values will be used. A jet is flying at 350 miles/hour in still air. It is traveling in the direction of 210°, where 90° represents North. Find the component form of vector r, which represents the jet's motion. -303.11 -175 350 -320.72 210 150 240 r = <__ cos __ , __ sin __> = <__ , __>
Answer:
-303.11 -175
Step-by-step explanation:
The jet has a speed of magnitude 350 miles/hour and travelling in a direction of 210°. Hence the jet can be represented with |r| = 350, θ = 210°.
The component form of the vector has both the x component (horizontal component) and the y component (vertical component) Therefore:
The horizontal component = [tex]r_x=|r|cos\theta=350*cos(210^o)= -303.11[/tex]
The vertical component = [tex]r_y=|r|sin\theta=350*sin(210^o)= -175[/tex]

Step-by-step explanation:
The sum of three consecutive odd integers is-219. What is the first number in the set?
Answer:
-75
Step-by-step explanation:
Let us consider the first odd number to be 'x'.
Thus:
1st odd number: x2nd odd number: x+23rd odd number: x+3According to the question, the sum of these three consecutive ODD numbers should be equal to -219
So,
x + x + 2 + x + 4 = -219
3x + 6 = -219
3x = -225
x = -75

Answer:
AB = 2
Step-by-step explanation:
Using the secant- secant theorem, that is
PA × PB = PD × PC , substitute values
10(10 + AB) = 8(8 + 7)
100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )
10AB = 20 ( divide both sides by 10 )
AB = 2
A restaurant menu shows the price for 2 chicken wings is $2.30 and the price for 6 chicken wings is $6.90. The function below gives the price, y, for x wing
y - 2.30 = 1.15(x - 2)
If this function is graphed in the coordinate plane, what is the y-intercept?
Answer:
y - intercept = 0 [(0,0)]
Step-by-step explanation:
Given the equation y - 2.30 = 1.15(x-2), the y-intercept is when x is 0.
So to find your answer, just substitute in 0 for x, and solve for y:
y - 2.30 = 1.15(x - 2) →
x = 0
y - 2.30 = 1.15(0 - 2) →
y - 2.30 = 1.15(-2)
y - 2.30 = -2.30 →
+2.30 +2.30
y = 0

9514 1404 393
Answer:
see attached
Step-by-step explanation:
Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change) and "rise" (vertical change) between the marked points.
In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.
The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.
If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
There are 15 clowns in a circus. Each clown has to act either happy or sad. Twelve of the clowns have red noses. Each of the seven happy clowns has a red nose. Five of the sad clowns have red noses. How many clowns have to act sad and do not have a red nose?
Answer:
3
Step-by-step explanation:
Each of the seven happy clowns has a red nose.This means there are (15-7) 8 sad clowns.
Five of the sad clowns have red noses.This means out of 8 sad clowns, 5 have red noses. So the clowns that have to act sad and have red noses are (8-5) 3.

Jaida has $200 to spend on flowers for a school celebration. She decides that the only flowers that she wants to buy are roses and carnations. Roses cost $1.45 each and carnations cost $0.65 each. Jaida buys enough roses so that each of the 75 people attending the event can take home at least one rose. Write an inequality to represent the cost constraint.
Answer:
[tex]1.45x+0.65y\leq 200[/tex]
Here, [tex]x[/tex] denotes the number of roses used for a school celebration and [tex]y[/tex] denotes the number of carnations used for a school celebration.
Step-by-step explanation:
Let [tex]x[/tex] denotes the number of roses used for a school celebration and [tex]y[/tex] denotes the number of carnations used for a school celebration.
Cost of 1 rose = $1.45
Cost of [tex]x[/tex] roses = [tex]\$1.45x[/tex]
Cost of 1 carnation = $0.65
Cost of [tex]y[/tex] roses = [tex]\$0.65y[/tex]
Total cost spend on flowers = [tex]1.45x+0.65y[/tex]
Total amount with Jaida = $200
So,
the inequality to represent the cost constraint is [tex]1.45x+0.65y\leq 200[/tex]

This equation can be written as :-
= 6 + 4x = x + 15
= 4x+6=x+15
= 4x + 6 − x = x + 15 − x
= 3x + 6 = 15
= 3x + 6 − 6 = 15 − 6
= 3x = 9
= 3 x 3 = 9
= x = 9 ÷ 3
= x = 3
Using this , let us solve the equation :-
= 6 + 4 × 3 = 3 + 15
= 6 + 12 = 3 + 15
= 18 = 18
Therefore , 6 + 4x = x + 15 = 18 ( x = 3 ) .

If its right plz give me Brainliest :)
Answer:
√64 = 8
Step-by-step explanation:
The Square root of 64 is 8
Square of ( +/-8) is 64. Since the negative numbers inside square root results in an imaginary number, so the square root must be positive and hence +8 is a square root of 64. The Answer is 8.
What is the simplest radical form of the square root of 64?
The "simplest radical form" of √64 is √26 if we define "simplest form" as a radical of a prime to an integer power.

Answer:
10.75
Step-by-step explanation:
The cost of an adult ticket is £6 more than that of a child ticket, so will be shown by c+6.
Now, we are told that the cost of four child tickets and two adult tickets is £40.50, so we can put this in an equation and solve for c:
(c+6)+(c+6)+c+c+c+c=40.50
6c+12=40.50
6c=28.50
c=4.75
so, a childs ticket is 4.75
now to find the cost of an adult ticket you add 6,
4.75 + 6
= 10.75

What is the slope-intercept form of equation of the line with a slope of 3 and y-intercept at origin?
Answer:
y=3x
Step-by-step explanation:
Equation is y=mx+b
Slope is 3/1 or 3x.
Y-intercept is at the origin or (0,0), so you take the y-coordinate.
Plug them into the equation.
y=3x+0 or y=3x
Write an equation for the line that passes through the given point and is parallel to the
graph of the given equation. Write your final equation in slope-intercept form.

The equation y = -3x + 5 represents a ____ function. The -3 represents the ____ of the line. This means that the slope is _____ . The 5 in the equation represents the ____ of the line. This is where the graph crosses the ____ axis.
Answer:
Step-by-step explanation:
The equation y = -3x + 5 represents a linear function. The -3 represents the slope of the line. This means that the slope is -3 . The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y-axis.
Compare the original equation with the standard form to get all the values.
[tex]y=-3x+5\\y=mx+c[/tex]
If we compare m= -3 and c=+5 where m is the slope/gradient and c is the y-intercept.
The equation y = -3x + 5 represents a Linear function. The -3 represents the slope of the line. This means that the slope is -3. The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y axis.
What is meant by linear function?A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation. So the way to describe linear functions is that for any given change in x, the change in y will always be the same value.Therefore,
Compare the original equation with the standard form to get all the values.
y = -3x + 5
y = mx +c
If we compare m = -3 and c = 5 where m is the slope/gradient and c is the y-intercept.
