Please help ٩(๑òωó๑)۶​

Answer:

Height of the cliff = 13.66 m

Step-by-step explanation:

Let the height of the cliff is 'x' m and distance between the base of the cliff and the boat is 'y' m.

From right triangle AOC,

tan 30° = \frac{\text{Opposite triangle}}{\text{Adjacent side}}

\frac{1}{\sqrt{3}}=\frac{x}{y}

y = x\sqrt{3} ------(1)

From right angle triangle BOC,

tan 45° = \frac{x}{y-10}

1=\frac{x}{y-10}

x = y - 10

y = x + 10 -------(2)

From equations (1) and (2),

x\sqrt{3}=x+10

x(\sqrt{3}-1)=10

x=\frac{10}{\sqrt{3}-1 }

x = 13.66 m

Therefore, height of the cliff is 13.66 m.

The line is parallel to y= 2x + 1 and passes through point (-2,-1).
inessss [21]

Answer:

y = 2x + 3

Step-by-step explanation:

To find the equation of a line, you need 2 things:

1) gradient/slope

2) 1 set of x and y coordinates

To find the slope:

If 2 lines are parallel, they have exactly the same gradient.

So, this line will have a slope of 2 as well (the slope of a line is the coefficient of x in the equation).

To find the equation of the line:

<u>Start with this generic equation:</u>

y - y1 = m (x-x1)

<u>We know that:</u>

(x1, y1) -> (-2, -1) and m= 2

<u>So, we can substitute for the equation:</u>

y- (-1) = 2 (x -(-2))

<u>Simplify, by expanding the brackets:</u>

y + 1= 2 (x+2)

y + 1 = 2x + 4

<u>Rearrange for y:</u>

y = 2x + 3

To double check:

1) The coefficient of x is the slope, we have 2x and the slop is 2, so that's correct

2) Sub in x= -2, and you should get y=-1

y = -4 + 3 = -1, so that's correct too

Hope that helped : )

Answer:

(D) 59 MPH

Step-by-step explanation:

To do this, we simply must look at what the table is giving us. From the top left corner, we can see that they are supplying us with the mileage between each of the cities given. Since we're going from Dallas to Lubbock, find Dallas on the y-axis and go left until you see Lubbock.

The distance between Dallas and Lubbock is <u>351 miles</u>. Now, we have to take our given information, our desired travel time of <u>6 hours</u>, and divide from the miles to get our speed:

mph=miles/hours\\mph=(351)/(6)\\mph=58.5

Then, we round up to the nearest whole number to get our answer of 59 miles per hour.
