Answer:

39.28cm^2

Step-by-step explanation:

area of the circle = 3.142 × radius^2

= 3.142 × 5^2

= 78.55cm^2

area of the semi circle = 1/2 × 78.55

= 39.28cm^2

Identify the maximum or minimum value and the domain and range of the graph of the function y = 2(x – 3)2 – 4.
NISA [10]
We are given the equation y = 2(x – 3)^2 – 4 and is asked for the domain and range of the following function. In this case, there is no radical sign so the domain includes all real numbers. The range has a minimum value of -4 since the squaring makes the value on the first term positive. Hence the answer is A.

What is the slope of the line whose equation is 2x−4y=10 ?
Olenka [21]

solve for y

2x−4y=10  

-2x       -2x      subtract -2x from both sides

-4y = -2x +10

-4            -4    Divide both sides by -4 (coefficient on y)

y = -2/-4x  + 10/-4

y = 1/2x - 5/2


the slope is the number on the x (coefficient)

and its 1/2

What is the area? Please explain steps so I can attempt to understand
yarga [219]

Answer:

12 \sqrt{2}

Step-by-step explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x= \sqrt{288}  = 12 \sqrt{2}

or :

you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = a\sqrt{2}

cm

so ;

a \sqrt{2}  = 24

a= 12 \sqrt{2}

hope this helps ^-^
