Answer:

  ? = 55

Step-by-step explanation:

Corresponding sides of similar triangles are proportional.

  RS/BA = RQ/BC

  ? /66 = 65/78 = 5/6

  ? = 66(5/6) = 55

The missing length is 55.

In january the depth of the lake was 1086 feet. In august the depth of the lake was 597.3 feet. What is the percentage decrease
tatiyna

Answer:

The percentage decrease in the depth is 45%

Step-by-step explanation:

January, lake depth = 1086 feet

august, lake depth = 597.3 feet

The decrease in depth = 1086 - 597.3

= 488.7 feet

Percentage decrease = decrease over January lake depth multiply by 100%

% decrease = (488.7/1086)*100%

=0.45*100%

= 45%

Answer:

  10.5 ft high

  5.3 ft horizontally

Step-by-step explanation:

The equation can be written in vertex form to answer these questions.

  f(x) = -0.2(x² -10.5x) +5

  f(x) = -0.2(x² -10.5x +5.25²) +5 +0.2(5.25²)

  f(x) = -0.2(x -5.25)² +10.5125

The vertex of the travel path is (5.25, 10.5125).

The maximum height is 10.5 feet, which occurs 5.3 feet (horizontally) from the point of release.

Find the distance from point A(−14, 5) to the line −x+2y = 14.
Ad libitum [116K]

Answer:

The distance from point A to given line is: 2√5 or 4.472 units

Step-by-step explanation:

Given equation of line is:

-x+2y= 14

And the point is:

A = (x_1,y_1) = (-14,5)

The standard form of equation of line is:

Ax+By+C = 0

Converting the given equation into standard form

-x+2y-14=0

The distance of a point (x1,y1) from a line is given by the formula:

d = \frac{|Ax_1+By_1+C}{\sqrt{A^2+B^2}}

In the given details,

A = -1, B = 2, C = -14

x1 = -14, y1 = 5

Putting the values in the formula

d = \frac{|(-1)(-14)+(2)(5)-14|}{\sqrt{(-1)^2+(2)^2}}\\d = \frac{14+10-14}{\sqrt{1+4}}\\d = \frac{10}{\sqrt{5}}\\d = \frac{5*2}{\sqrt{5}}\\d = \frac{\sqrt{5}*\sqrt{5}*2}{\sqrt{5}}\\d = 2\sqrt{5}\\d = 4.472\ units

Hence,

The distance from point A to given line is: 2√5 or 4.472 units
