The correct answer is the 3rd option.
The component form of a vector is to write in the form (x, y) the x and y component of a vector.
Since the vector starts at (0, 0) and ends at (5, -8) We can rest the start point to the end point to get the components of the vector:
The component for is:
The magnitude of a vector is its' module, we calculate it by:
Where x and y are the components of the vector. In this case:
The whole answer is:
Which is option 3.
Answer:
4
Step-by-step explanation:
So your equation is 1.6(x-y)/2
Since x=10, and y=5, we need to substitute the amounts in to the equation.
so...
1.6(10 -5)/2
Using PEMDAS, parenthesis comes first. So solve what 's in the parenthesis (10 - 5).
So..
1.6(5)/2
Next, multiply 1.6 by 5.
1.6 x 5 = 8.
So you are left with the equation
8/2
and 8 divided by 2 is...
4!
Answer:
-40 °F = -40 °C
Step-by-step explanation:
(1) F = 1.8 C + 32
If the Fahrenheit and Celsius temperatures are the same, then
(2) F = C Substitute (2) into (1)
C = 1.8C + 32 Subtract 1.8 C from each side
C – 1.8 C = 32 Combine like terms
-0.8C = 32 Divide each side by -0.8
C = -32/0.8
(3) C = -40 Substitute (3) into (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
So, -40 °F = -40 °C
The thermometer below shows that -40 °F = -40 °C.
X = # of posters, y = total cost
y = 2x + 250
y = 1000
1000 = 2x + 250
1000 - 250 = 2x
750 = 2x
750/2 = x
375 = x....so 375 posters can be printed
==========================
y = total cost, x = # of miles
y = 3x + 3
y = 117
117 = 3x + 3
117 - 3 = 3x
114 = 3x
114/3 = x
38 = x.....so the car was towed 38 miles
If there are no horses, there will be no horses divided evenly into each of the three stables.
Hopefully this helps :)
