Mathematics

Answer:

32.4 ft

Step-by-step explanation:

the perimeter of the half circle = ( 1/2 * 3.1 * 8) - 8 = 4.4 ft

the total perimeter = 10 + 8 +10 + 4.4 = 32.4 ft

( the right-side width of the rectangle is the diameter of the circle because it passes the origin point. Then you just need to calculate the perimeter of that half circle. Remebering to subtract the length of that diameter because it is not included in the total diameter.)

Which of the following lines are parallel to 2Y - 3X = 4?
dimulka [17.4K]

Answer:

B. Y = 6/4 X

Step-by-step explanation:

Well to find its parallel line we need to put,

2y - 3x = 4 into slope-intercept.

+3x to both sides

2y = 3x + 4

Now we divide everything by 2,

y = 3/2x + 2

So a line that is parallel to the given line will have the same slope but different y intercept, meaning we can cross out choices A and C.

To check look at the image below ↓

<em>Thus,</em>

<em>answer choice B. Y = 6/4 X is correct.</em>

<em>Hope this helps :)</em>

24 cm ,18cm ,c <br> We are looking for c
Ierofanga [76]

Step-by-step explanation:

we can find the value of c by Pythagoras theorem

according to Pythagoras theorem

h² = a² + b²

where

h = hypotenuse (i.e. longest side of a right angled triangle)

a = side

b = base

so, we have to find h or hypotenuse here

h² = (24)² + (18)²

h = 576 + 324 = 900

h² = √900 = 30

c = 30

therefore, value of c is 30.

Hope this answer helps you dear!

Iiana started to evaluate the function f(x)=2x^2-3x+7 for theinput value 2
Vitek1552 [10]

Answer:

The output for x = 2 is

\therefore f(2)=9

Step-by-step explanation:

Function:

A function is like a machine that gives an output for a given input.

A function has an independent variable which is called the input of the function.

The output for a given input is called the dependent variable.

Here. 'x' independent variable

f(x) is the function dependent variable

f(x)=2x^{2}-3x+7

So Put x = 2 in the f(x)  we get

f(2)=2(2)^{2}-3(2)+7= 2\times 4 -6 +7 = 8+1=9

The output for x = 2 is

\therefore f(2)=9
