Answer:

the answer is C because according to the graph, the y-intercept is -6 and the slope is 3.

slope is rise over run, so find a point thats directly on a corner of the grid (i chose the y-intercept) and then count to see how many lines are between that point and the next one that's directly on the lines. (it's (1, -3)) making the slope 3/1 or 3

Answer:

e=15.8

Step-by-step explanation:

Well we use the law of cosines

e^2=11^2+6^2-2(11)(6)cos(134)

$e^{2} =121+36-132cos134\\e^2=157-132cos143\\e^2=248.694....\\e=15.8$

The owner of a 4000-gal oil truck loads the truck with gasoline and keroseno. The profit on each gallon of gasoline is 16e and o

lilavasa [31]

Answer:

There were 35 gallons of gasoline and 500 gallons of kerosene.

Step-by-step explanation:

Step 1: Write data for equation 1

Let gallons of kerosene be x

Let gallons of gasoline be y

Total capacity of truck is 4000

Step 2: Form equation 1

x + y = 4000

Step 3: Write data for equation 2

Profit of total gallons of kerosene is 0.12x

Profit of total gallons of gasoline is 16y

Total profit is $620

Step 4: Form equation 2

0.12x + 16y = 620

Step 5: Find x in terms of y from equation 1

x + y = 4000

x = 4000 - y

Step 6: Substitute value of x in equation 2

0.12x + 16y = 620

0.12 (4000 - y) + 16y = 620

480 - 12y + 16y = 620

4y = 620 - 480

y = 140/4

y = 35

Step 7: Substitute value of y in equation 1 to find x

0.12x + 16y = 620

0.12x + 16 ( 35 ) = 620

0.12x = 60

x = 500

There were 35 gallons of gasoline and 500 gallons of kerosene.

If the triangle is not right-angled, and there is not a matching pair, you will need the _____________ Rule.

nekit [7.7K]

Answer:

Cosine

Step-by-step explanation:

If the triangle is not right-angled, and there is not a matching pair, you will need the Cosine Rule..

and the formula used will be: $a^2 = b^2 + c^2 - 2 b c cos A$

In the opposite case if the triangle is not right-angled, and there is a matching pair, you will need the Sine Rule..

For the coordinates of P and M (the midpoint) are given. Find the coordinates for Q.

zhenek [66]

Given an endpoint of a segment and a midpoint, the other endpoint can be obtained by manipulation of the midpoint formula. The said formula is shown below:

Let: (a,b) = coordinates of point 1 ; (c,d) = coordinates of point 2; (e,f) = coordinates of the midpoint

Midpoint = ( (a+c)/2 , (b + d)/2 )

From the formula: (a+c)/2 = e ; (b + d)/2 = f

Since we are already given an endpoint and the midpoint, we can solve for the other endpoint using the obtained equations. This is shown below:

(a+c)/2 = e
(3 + c)/2 = 0
c = -3

(b + d)/2 = f
(11 + d)/2 = 0
d = -11

Therefore, the coordinates of the other point is Q(-3,-11)
