Answer:

L_s=7.85\ m

Step-by-step explanation:

<u>Length Of Semicircles </u>

The length of a circle or radius r is

L=2\pi r

A semicircle has half this length:

L_s=\pi r

The radius of the flowerbed is 2.5 m, thus the length of the edging material needed to border the lawn design is

L_s=\pi (2.5)=(3.14)(2.5)=7.85\ m

\boxed{L_s=7.85\ m}

Which equation represents a line parallel to the line shown on the graph? On a coordinate plane, a line goes through (0, 8) and
dezoksy [38]

Answer:

  • B) y = negative 4 x + three

Step-by-step explanation:

<u>Find the slope of the line that goes through (0, 8) and (2, 0):</u>

  • m = (y₂ - y₁)/(x₂ - x₁)
  • m = (0 - 8) / (2 - 0) = -8/2 = -4

Parallel lines have equal slopes.

<u>Looking at the choices we see only one of them has the slope of  -4:</u>

  • y = -4x + 3

F(x)=3/x+2-√x-3 f(19)=​
77julia77 [94]

Answer:

  • - 27/7

Step-by-step explanation:

Given

  • f(x)=3/(x+2) - √(x-3)

To find

  • f(19)

Solution

  • f(19) =​ 3/(19 + 2) - √(19 - 3) = 3/21 - √16 = 1/7 - 4 = - 27/7

A baby bird jumps from a tree branch and flutters to the ground. The function "f" models the bird's height (in meters) above the
AURORKA [14]

The answer to this question will depend on the function f itself. Basically you will find the height in meters above the ground of the bird when it jumped when the time t=0s. This is substsitute every t in the function for a value of zero and that way you will get the bird's height at the time it jumped. If you were given a graph for this function, you can find the y-intercept of the graph and that will be the answer as well. The question could be written like this:

A baby bird jumps from a tree branch and flutters to the ground. The function "f(t)-4.9t^{2}+25" models the bird's height (in meters) above the ground as a function of time (in seconds) after jumping. What is bird's height above the ground when it jumped.

Answer:

25m

Step-by-step explanation:

Once your function is given, you can substitute t=0 since 0s is the time measured at the moment the bird jumped. So our function will be:

f(0)=-4.9(0)^2+25

f(0)=25m

So the height of the bird above the ground when it jumped is 25m in this particular function.

Solve by any method <br> y= -7x+10<br> y= -3x+6
AnnyKZ [126]
Y=1
To get it, you use the method of substitution. So you swtich the top y by the equation of the bottom=-3x+6=-7x+10. You first add 7x to each side=4x+6=10 then you minus 6 from each side=4x=4 which is 1
