Step-by-step explanation:

double negative is a plus sign

13--9=22

Answer 2

Answer: 22

Step-by-step explanation:

Here, we need to know the concept of changing signs. Under any circumstances, if there is a "-" sign outside of parenthesis, the signs inside need to be the opposite. If you are still not very clear, I can provide some examples below:

1-(+1) ⇒ there is a "-" sign, so we need to convert the sign inside "+" to "-" ⇒ 1-1 ⇒ 02-(-1) ⇒ there is a "-" sign, so we need to convert the sign inside "-" to "+" ⇒ 2+1 ⇒ 3

-------------------------------------------------------

Given

13 - (-9)

⇒There is a "-" sign outside

⇒We need to convert the sign inside "-" to "+"

⇒13+9

⇒22

Hope this helps!! :)

Find the area of the regular polygon. Round your answer to the nearest whole number of square units.​

Answers

Answer:

total area = 39.6 square units

Step-by-step explanation:

determine the inside angle

360 / 5 = 72°

half of the triangle = 36°

given:

adj = 3.3

Ф = 36°

length of the opp of a small triangle is = adj. tan Ф

opp = 3.3 * tan 36 = 2.4

area of a triangle = 1/2 b * h   x  2 tringles

area =( 1/2 * 2.4 * 3.3  ) * 2

area = 7.92  multiplied by 5 equal shapes

total area = 7.92 * 5

total area = 39.6 square units

hope this helps

mark me as a brill please

good luck

The total area of the regular polygon should be considered as the 39.6 square units.

Calculation of the total area of the regular polygon:

But before that following things should be calculated

first determine the inside angle i.e.

[tex]= 360 / 5[/tex]

= 72°

Now

half of the triangle = 36°

Since

adj = 3.3

Ф = 36°

So,

opp =[tex]3.3 * tan 36[/tex] = 2.4

Now

area of a triangle =[tex]1/2 b * h * 2[/tex]

[tex]=( 1/2 * 2.4 * 3.3 ) * 2\\\\= 7.92 * 5[/tex]

= 39.6 square units

hence, The total area of the regular polygon should be considered as the 39.6 square units.

Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.

Answers

Answer:

100.48 cm³

Step-by-step explanation:

Volume of a cone, V = 1/3 * pi * r² * h

Radius, r = 4 cm ; h = 6cm

V = 1/3 * 3.14 * 4² * 6

V = 1/3 * 3.14 * 16 * 6

V = 3.14 * 16 * 2

V = 3.14 * 32

V = 100.48 cm³

Hence, the volume of the cone is 100.48 cm³

The angle between the ramp and the horizontal is 11.54 degrees

Step-by-step explanation:

Here, we want to get the angle between the ramp and the horizontal

What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle

Now, the angle we want to calculate is the angle that faces the measure 2 m

The given measure of 10 m will represent the hypotenuse of the right triangle

The trigonometric ratio that links the hypotenuse and the opposite is the sine

The sine is the ratio of the opposite to the hypotenuse

Thus, we have it that;

sin theta = opp/hyp

sin theta = 2/10

sin theta = 0.2

theta = sin^-1 0.2

theta = 11.54

Leon makes a rectangular logo for his skateboarding club. He cuts from fabric two copies of the trapizoid shown and joins them to form a rectangle. What is the area of the rectangular logo leon makes

Answers

Answer:

Area of the rectangular logo is 56cm²

Step-by-step explanation:

If we look at the picture the 2 trapezoids make a rectangle.

The length of the rectangle = 9+5= 14 cm  and the breadth = 4 cm

Area of the rectangle = Length * breadth

A= 14*4= 56cm²

Area of the rectangular logo is 56cm²

Area of the trapezoid = 28 cm²

Area of the trapezoid = 1/2height( base1+ base2)

                              = 1/2 (4) ( 5+9)

                               = 2(14)= 28 cm²

Area of 2 trapezoids = 28 cm²+28 cm²=  56 cm²

Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) is a rhombus

Answers

Answer:

The quadrilateral is a rhombus

Step-by-step explanation:

Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) Is a rhombus

A rhombus is a quadrilateral with all its sides equal to each other.

We prove this using the formula

√(x2 - x1)² + (y2 - y1)²

When given vertices (x1, y1) and (x2, y2)

For sides PL

P(-2, 3) L( 2, 6)

√(2 - (-2))² + (6 - 3)²

= √4² + 3²

= √16 + 9

= √25

= 5 units

For sides LU

L( 2, 6) U (7,6)

√(7 - 2)² + (6 - 6)²

= √5²

= √25

= 5 units

For side US

L( 2, 6) U (7,6)

= √(7 - 2)² + (6 - 6)²

= √5² + 0²

= √25

= 5 units

P(-2, 3), S(3, 3)

= √(3 - (-2))² + (3 - 3)²

= √5² + 0²

= √25

= 5 units

From the above calculation,

PL = LU = US = PS = 5 units

Hence, the above quadrilateral is a rhombus

Write an equation of the line that passes through point P and is parallel to the line with the given equation: P(2,5) Y-1=4x​

Answers

Given:

The equation of a line is:

[tex]y-1=4x[/tex]

A line parallel to the above line passes through the point P(2,5).

To find:

The equation of the parallel line.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]         ...(i)

Where, m is the slope and b is the y-intercept.

The given equation is:

[tex]y-1=4x[/tex]

It can be rewritten as

[tex]y=4x+1[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=4[/tex]

It means the slope of the given line is 4.

We know that the slopes of two perpendicular lines are equal. So, the slope of the required parallel line is also 4.

The parallel line passes through the point P(2,5) with slope 4, thus the equation of the parallel line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-5=4(x-2)[/tex]

[tex]y-5=4x-8[/tex]

[tex]y=4x-8+5[/tex]

[tex]y=4x-3[/tex]

Therefore, the equation of the required parallel line is [tex]y=4x-3[/tex].

The function g(x) is a translation of f(x) = (x + 3)2 – 10. The axis of symmetry of g(x) is 5 units to the right of f(x) . Which function could be g(x)?

g(x) = (x – 2)2 + k
g(x) = (x + 8)2 + k
g(x) = (x – h)2 – 5
g(x) = (x – h)2 – 15

Answers

Answer:

a.

g(x) = (x – 2)2 + k  

Step-by-step explanation:

The function that could be g(x) is (a) g(x) = (x - 2)^2 + k

How to determine the function?

The function f(x) is given as:

f(x) = (x + 3)^2 - 10

The axis of symmetry of g(x) is 5 units to the right of f(x).

This means that:

g(x) = f(x - 5)

So, we have:

f(x - 5) = (x - 5+ 3)^2 + k

Evaluate the difference

f(x - 5) = (x - 2)^2 + k

Substitute g(x) = f(x - 5)

g(x) = (x - 2)^2 + k

Hence, the function that could be g(x) is (a) g(x) = (x - 2)^2 + k
