Answer:

45 cm²

Step-by-step explanation:

Area of the two triangles:

A = 1/2*b*h

A = 1/2*3*4

A = 1/2*12

A = 6
Area of the two rectangles:

A = bh
A = 4*3
A = 12
Area of square:
A = bh
A = 3*3

A = 9
Now add these numbers together to get total area:

6 + 6 + 12 + 12 + 9 = 45

Work Shown:

mu = 27989 = population mean

sigma = 3250 = population standard deviation

z = (x-mu)/sigma

z*sigma = x-mu

x = z*sigma + mu

x = 0.34*3250 + 27989

x = 29,094

The salary of $29,094 corresponds to the z score of 0.34.

This indicates the salary $29,094 is exactly 0.34 standard deviation units above the mean.

Answer:

I think the answer is 1.78

Step-by-step explanation:

The diameter of the sphere will be equal to 4.59 feet.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

Given that:-

The area of the sphere will be = 20 / 2 = 10 square feet

The diameter of the sphere will be calculated as:-

Area = 4 π r  

10  =  4 π r

r  =  10 / (  4 π )

r  =   0.79 feet

D = 2r = 2 x 0.79 = 1.59 feet

Therefore the diameter of the sphere will be equal to 4.59 feet.

The altitude of the plane is 8 miles

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

we know that in the right triangle ABC

tan function is ratio of opposite side and adjacent side

tan(72°)=h/x

h=xtan(72°) ....... equation 1

In the right triangle ABD

tan(55°)=h/(x+3)

h=(x+3)tan(55°) ..... equation 2

From equation 1 and 2

xtan(72°)=(x+3)tan(55°)

xtan(72°)-xtan(55°)=3tan(55°)

x[tan(72°)-tan(55°)]=3tan(55°)

x=3tan(55°)/[tan(72°)-tan(55°)]

We have to find the value of h

h=xtan(72°)

h=[3tan(55°)*tan(72°)]/[tan(72°)-tan(55°)]

h=8 miles

Hence, the height is 8 miles of the plane.

#SPJ7

Answer:

y = -[tex]\frac{5}{6}[/tex]x + 9

Step-by-step explanation:

0.5x + 0.6y = 5.4

0.6y = -0.5x + 5.4

Multiply 10 on all sides.

6y = -5x + 54

Divide 6 on all sides.

y = -[tex]\frac{5}{6}[/tex]x + 9

Answer:

85

Step-by-step explanation:

The sum of the angles inside a triangle is 180 degrees.

A circle is 360 degrees, making half of it be 180 as well.

Since there are 121 degrees already marked, subtract it from 180 and you will get 59 degrees.

36 + 59 = 95

180 - 95 = 85 degrees.

Answer:

x = 85

Step-by-step explanation:

angles of a triangle = 180 degrees (all angles must equal 180)

if you minus 121 from 180, it will give the interior angle which is 59 degrees

therefore 59 + 36 + x  = 180

to find x plus 59 and 36 = 95 degrees

180 - 95 = 85

x = 85 degrees

Answer: Choice D) x can be anything but 13

========================================================

Explanation:

The domain of [tex](f \circ g)(x) = f(g(x))[/tex] is the same as the domain of g(x)

The domain for g(x) is [tex]\{x|x \ne 13\}[/tex] saying we can plug in any number we want as long as it's not 13. This is to avoid dividing by zero. The same domain applies for the composite function because

[tex]f(x) = x+7\\\\\\f(g(x)) = g(x)+7\\\\\\f(g(x)) = \frac{1}{x-13}+7\\\\\\(f \circ g)(x) = \frac{1}{x-13}+7\\\\\\[/tex]

and we can see that we still need to kick out x = 13 from the domain to avoid the division by zero issue.

Can you redo it's a little too much

Answer:

Bro thats a lot of questions

Step-by-step explanation:

I am guessing you meant y=-2(x-4)^3+1 from x^3

From the parent cubic function x^3,

a(x-k)^3+h is its transformation and it would be vertical stretch by a, followed by a horizontal translation by k and vertical translation by h

Your equation follows the same format it has a negative sign at the front before the ( ) which means a reflection over the x axis at the beginning

SO your graph is a

1.reflection over the x axis

2.followed by a vertical stretch by 2

3.followed by a horizonal translation to the right 4

4.followed by a vertical translation up 1

from x^3
