Answer:

area: 27

Step-by-step explanation:

Sides: a = 10.296 b = 14.213 c = 6

The calculation of the triangle progress in two phases. The first phase is such that we try to calculate all three sides of the triangle from the input parameters. The first phase is different for the different triangles query entered. The second phase is the calculation of other characteristics of the triangle, such as angles, area, perimeter, heights, the center of gravity, circle radii, etc. Some input data also results in two to three correct triangle solutions (e.g., if the specified triangle area and two sides - typically resulting in both acute and obtuse) triangle).

which of the following is q point slope equation of a line that passes through the point (5,2)and (-1,-6)

Salsk061 [2.6K]

Answer:y - y1 = m(x + x1)

m = (y2 - y1)/(x2 - x1) = (-6 - 2)/(-1 - 5) = -8/(-6) = 4/3

y - 2 = 4/3(x - 5) is a possible answer

y + 6 = 4/3(x + 1) is also a possible answer

What is the diameter of a circular field whose area is 616cm^2<br><br>

Oksana_A [137]

Answer:

Step-by-step explanation:

$d=2\sqrt{\frac{A}{\pi}} =2\sqrt{\frac{616}{\pi} }$ ≈ $28.00563cm$

rounding 28.00563 to 28.

So hence, your answer is 28cm

The quadratic equation -6=x^2+4x-1 in Standard form . What is the value of c in his new equation

Vitek1552 [10]

Answer:

c = 5

Step-by-step explanation:

A quadratic equation in standard form is

ax² + bx + c = 0 : a ≠ 0

Given

- 6 = x² + 4x - 1 ( add 6 to both sides )

0 = x² + 4x + 5 ← in standard form

with c = 5

A board is cut so that its length is changed from 8 feet to 6.5 feet. What is the percent of change in length? Round your answer

Schach [20]

it went from 8 to 6.5, namely 8 - 6.5 = 1.5.

if we take the 8 to be the 100%, what is 1.5 off of it in percentage?

$\bf \begin{array}{ccll}amount&\%\\\cline{1-2}8&100\\1.5&x\end{array}\implies \cfrac{8}{1.5}=\cfrac{100}{x}\implies x=\cfrac{1.5\cdot 100}{8}\implies x=18.75$

well, we can round that up to 18.8%, however since it's a subtraction from the board, we can say is -18.8%, a negative percent, because is a percent that was taken out of it.
