To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, mea

Vikki [24]

Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
$tan\:26^{\circ} =\frac{AE}{120}$
So,
$AE=120\:tan\:26^{\circ}$
$AE=58.53\:$

Therefore, the overall height of the pole is
$AB=58.53+8=66.53\:feet$

The height of the pole is 66.53 feet.

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (

Alenkinab [10]

Answer:

$Width = 20\ in$

$Area = 400\ in^2$

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

$Height = 31\ in + 9\ in$

$Height = 40\ in$

The width which is half the height is:

$Width = \frac{1}{2} * Height$

$Width = \frac{1}{2} * 40\ in$

$Width = 20\ in$

The area is:

$Area = \frac{Height * Width}{2}$

$Area = \frac{40\ in * 20\ in}{2}$

$Area = 40\ in * 10\ in$

$Area = 400\ in^2$

The equation of the line of best fit of a scatter plot is y = 12x + 7. What is the slope of the equation? −12 −7 12 7

BabaBlast [244]

Well,

Slope-intercept form is given as follows:
y = mx + b

In this equation, "m" is the slope, and "b" is the y-intercept.

y = 12x + 7

We can clearly see that the 12 in the equation is the "m" in the general slope-intercept form.

Therefore, the slope of the equation is 12.
