What is the slope of a line that passes through the pair of points (1,7) and (10,1)?
sammy [17]

Answer:

-2/3.



Step-by-step explanation:

To find the slope of a line given two points, you should use the formula, Slope=y2-y1/x2-x1.In this exercise is given the coordinates of two points and it is asked to find the slope of the line which intercepts both points, which are (1,7) and (10,1). To find the slope, you should substitute the given coordinates into the previous mention formula. Slope=y2-y1/x2-x1Slope=(7-1)/(1-10)Slope=-6/9Slope=-2/3The slope of the line that passes through the points.

Use 3.14 for PI( π ) <br><br> Diameter: 5 ft <br> Formula: A= πr2
Liula [17]

Answer:

\boxed {\boxed {\sf 19.625 \ ft^2}}

Step-by-step explanation:

The area of a circle is found using this formula:

a= \pi r^2

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

  • r=d/2
  • r= 5 ft/2
  • r= 2.5 ft

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

a= (3.14)* (2.5 \ ft)^2

Solve the exponent.

  • (2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

a= (3.14)*(6.25 \ ft^2)

Multiply.

a=19.625 \ ft^2

The area of the circle is <u>19.625 square feet.</u>

To measure a stone face carved on the side of a​ mountain, two sightings 750 feet from the base of the mountain are taken. if th
Sergeeva-Olga [200]

Answer: 57.8512 feet (approx)

Step-by-step explanation:

Let h be the height of the stone face.

The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°

⇒ The distance of the base of the stone face from the base of the mountain = 750\times tan 33^{\circ}=750\times 0.64940759319=487.055694898

The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,

Therefore,

The distance of the top of the stone face from the base of the mountain  = (h + 487.055694898) feet

By the trigonometry,

\frac{h + 487.055694898}{750}=tan36^{\circ}

h + 487.055694898=0.726542528\times 750

h =544.906896004-487.055694898=57.8512011059\approx 57.8512

Therefore, the height of the stone face is 57.8512 feet (approx).
