Answer:

πr

Step-by-step explanation:

We know the perimeter of the circle is 2πr , half the perimeter will be equal to ,

=> 2πr/2

=> πr

<h3><u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is</u><u> </u><u>πr </u><u>.</u></h3>

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Step-by-step explanation: .

The graphs of functions f(x) and g(x) = f(x) + k are shown below. Graph of line f of x going through ordered pairs 0, 1 and 2, 6
mash [69]
The cut point with the y axis for both graphs occurs when x = 0
 We have then:
 For f (x):
 The cut point with the y axis is:
 f (0) = 1&#10;
 For g (x):
 The cut point with the y axis is:
 g (0) = -1&#10;
 Therefore, the value of k is given by the vertical displacement of the graph k units.
 We have then:
 g (0) = f (0) + k&#10;
 From here, let's clear k:
 k = g (0) - f (0)&#10;&#10;k = - 1- 1&#10;&#10;k = -2
 Answer:
 
The value of k is -2

Graph time...........
user100 [1]

Answer:

The third graph is the graph of the given function

Step-by-step explanation:

A simple technique that can be used to identify the graph that matches the given function is; determination of the x and y-intercepts. In this case, determining the y-intercept and then using elimination will suffice in matching the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). The third graph is the graph of the given function.

What is the surface area of this triangular pyramid the height is 4 the base and width is 4 and the bottom back line is 4 and th
valentinak56 [21]

Answer:

37 yd²

Step-by-step explanation:

The computation of the surface area of this triangular pyramid is shown below:

The surface area of this triangular pyramid  is

But before that

Lateral area = 3(1 ÷ 2) × base × height

= (3 ÷ 2)(4 yd)(5 yd)

= 30 yd²

Now

base area = 1 ÷ 2 × base × height

= 1 ÷ 2(4 yd)(3.5 yd)

= 7 yd²

Now the total surface area is  

surface area = lateral area + base area

= 30 yd² + 7 yd²

= 37 yd²

Question 13 (1 point),
Firlakuza [10]

13: Since f(1)=10, the sequence must start with 10. We have only one sequence starting with 10, and indeed it verifies f(n+1)=f(n)-2, i.e. the next term is 2 less than the previous one.

14: If y varies directly with x, then there is a constant of variation k such that

\dfrac{y}{x}=k \iff y=kx

In your case, F varies directly with m, with a constant of variation of 32.2, so we have

F=32.2m
