Answer:

136 m^2

Step-by-step explanation:

Surface area is the area of all the sides added together.

Front = triangle = <u>b * h</u>  = <u>6 * 4</u> = 12                   12

                               2           2

Back = triangle = <u>b * h</u>  = <u>6 * 4</u> = 12                   12

                               2           2

Right = Rectangle = l * w = 7 * 5 = 35              35

Left = Rectangle = l * w = 7 * 5 = 35                35

Bottom = = Rectangle = l * w = 7 * 6 = 42     <u>  42</u>

                                                                        136 m^2

Answer:

surface area = 136 m^2

Step-by-step explanation:

The prism has 5 faces.

Faces 1 and 2: The front and back faces are two congruent triangles with base 6 m and height 4 m.

Face 3: The bottom face is a rectangle with length 7 m and width 6 m.

Faces 4 and 5: The left and right inclined faces are two congruent rectangles with length 7 m and width 5 m.

area = area of faces 1 and 2 + area of face 3 + area of faces 4 and 5

area of triangle = bh/2

area of rectangle = LW

area = 2 * 6 m * 4 m / 2 + 7 m * 6 m + 2 * 7 m * 5 m

area = 24 m^2 + 42 m^2 + 70 m^2

area = 136 m^2

Answer: surface area = 136 m^2

What is the range of the function y= 2sinx​
Nana76 [90]
<h2>Hello!</h2>

The answer is: [-2,2]

<h2>Why?</h2>

The range of a function shows where the function can exist in the y-axis.

To know the range of the function, we have to isolate x,

So

y=2sinx\\\frac{y}{2}=sinx\\ Sin^{-1}(\frac{y}{2}) = x

The only possible values that y can take go from -2 to 2. Taking values out of these values will give as result a non-real number.

Therefore,

The range of  the function is [-2,2]

15 points for someone who can answer &amp; explain this to me thanks
iris [78.8K]

Answer:

see explanation

Step-by-step explanation:

Given

\frac{9}{a^2+9a+20} , \frac{7a}{a^2+11a+28}

Factor the denominators of both fractions

\frac{9}{(a+4)(a+5)} , \frac{7a}{(a+4)(a+7)}

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

\frac{9(a+7)}{(a+4)(a+5)(a+7)} , \frac{7a(a+5)}{(a+4)(a+5)(a+7)} , then

\frac{9a+63}{(a+4)(a+5)(a+7)} , \frac{7a^2+35a}{(a+4)(a+5)(a+7)}
