Solve the equation. Graph the solution(s) if possible.<br><br> ∣x−3∣+4=9
Mazyrski [523]

Answer:

x=8

x=-2

Step-by-step explanation:

∣x−3∣+4=9

= ∣x−3∣=5

<u>Positive term: (x-3)</u>

  (x-3) = 5

Rearrange and Add up

  x = 8

<u>Negative term: -(x-3)</u>

Multiply

     -x+3 = 5  

Rearrange and Add up

     -x = 2  

Multiply both sides by (-1)

     x = -2

The radius of a circle is 3 miles. What is the length of a 90° arc?
stealth61 [152]

Answer:

The length of the arc is 4.6375 miles

Step-by-step explanation:

Firstly, find the perimeter of the circle by doing 2*pi*r, you'll get about 18.55 miles.

2*pi*r ---> 2*pi*3 ---> 6*pi ---> ≈ 18.55 miles

Next, plug in x/360, where 360 is the total arc of a circle, and x is the arc you need.

x/360 ---> 90/360 ---> = 0.25

Lastly multiply the two numbers.

18.55 * 0.25 ---> 4.6375 miles is your answer.

A single little brown bat can eat up to 1,000 mosquitoes in a single hour. Express in scientific notation how many mosquitoes a
Nastasia [14]
Our final answer must represent "number of mosquitos."  This verifies that the correct calculation would be

1000 mosquitos              10.5 hours
-----------------------  x   --------------------
         1 hour                           1

Multiply this out.  Note that "hours" will cancel.

Whats your result?

Supposing that your result looked like   xxxxx times 10^0,

you'd convert this into scientific notation by moving the decimal place four units to the left (obtaining x.xxx) and then increasing the exponent of 10 from zero to four (obtaining 10^4).

Then your answer would have the form x.xxx times 10^4 (mosquitos)

Given sin b = .88 find angle b in radians
vazorg [7]

first convert 0.88 to degrees

 so arcsin(0.88) = 61.642 degrees

 Arcsin on a calculator is sin^-1

then to convert to radians divide degrees by 180 and multiply that by PI

so (61.642/180) x PI = 1.076 radians

Find the area. simplify your answer.
PolarNik [594]

Answer:

The area is:

2 {x}^{2}

Step-by-step explanation:

Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.

Therefore:

a = 2x (x) = 2 {x}^{2}
