i need a little help with this geometry

Answer:

4

Step-by-step explanation:

cos(-π) = -1 [in radians]

3-(-1) = 4

There are many ways to answer this but, I'll try to explain it.

You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.

Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.

The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.

Hope this helps.

Answer:

3x - y = -3

Step-by-step explanation:

divide everything by 4, the greatest common factor. That's all you need to do.

Answer: y=3x+3

Step-by-step explanation:

12x -4y= -12

subtract 12x from both sides

-4y= -12x-12

Divide everything by -4 to make y positive and alone

y=3x+3

Answer:

96

Step-by-step explanation:

The ratio of the measure of sides of a triangle are 8:15:17

The perimeter is 480

8x + 15x + 17x= 480

40x= 480

x = 480/40

x = 12

Therefore the measure of the shortest side of the triangle can be calculated as follows

8x

8×12

= 96

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

[tex]h=32t - 16t^2[/tex]

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.

Answer:1,2,3,5

Step-by-step explanation:

Answer:

2=41     1=49      3=49

Step-by-step explanation:

Angle 2 = 41 because it is directly across the given angle.

Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.

41+41=82

180-82=98

98 / 2 = 49

Angles and 3 both equal 49

Answer:

2=41°(Alternate Interior angles)

1=41°(diagonal of rhombus bisects the interior angles)

3=49°(180-82/2)

Step-by-step explanation:

Answer:

42.667 mm to 42,673 mm

Step-by-step explanation:

42.67-0.003=42.667

42.67+0.003=42.673

Add and subtract the discreprency from the standard size.

Answer:

The slope is a zero slope. This means that the line is a straight, horizontal line.

Step-by-step explanation:

Use the slope formula.

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

5-5/-18-18 = 0/-36

The requried range of the radio station is given as 1256 square miles.

The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.

Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles

Thus, the requried range of the radio station is given as 1256 square miles.

#SPJ2

Answer:

14 : 12 , 21 : 18 and 28 : 24

Step-by-step explanation:

Answer:

1. 4y-12

2. c

For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.

For #2 you factor out the 3 and you get 3(5x+1)

Answer:

4y-12

Step-by-step explanation:

Multiply the outside number by the numbers in the bracket.

Example:4×y=4y Because y=1

4×3=12

2.Answer C

3(5x+1)

3×5x=15x

3×1=1

Which is equivalent to 3(5x+3)

Answer:

9/28

Step-by-step explanation:

-1/4 ÷ (-7/9)

= -1/4 x -9/7

- x - = +

So, 9/28 #

Step-by-step explanation:

Area of triangle (A1)

= 1/2 * b *h

= 1/2 * 1 * 1

= 1/2 ft

Area of rectangle (A2)

= L * b

= 3 *1

= 3 ft

Total area

= A1 + A2

= 1/2 + 3

= (1 + 6 ) / 2

= 7/2 ft²

= 3.5 ft²

Hope it will help :)

Complete question :

Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.

Millitary status _________ female ____ Male

In armed forces _________ 28 _______ 59

Millitary dependent ______ 928 ______ 781

Civilian _______________ 26393 ___27330

Answer:

Male = 0.4193

Female = 0.5087

Step-by-step explanation:

To obtain the marginal distribution of gender :

Total number of civilians (male + female)

(26393 + 27330) = 53,723

Male :

P(male) = number of male / total

P(male) = 26393 / 53,723 = 0.4912793

P(Female) = number of Female / total

P(Female) = 27330 / 53,723 = 0.5087206

Answer:

44 is 4/5 out of 55 (44/55 = 4/5)

Step-by-step explanation:

55 can be divided into fifths.

1/5 = 11 or 11/55

11 x 4 = 44
