Answer: x = -2 and x = -3

Step-by-step explanation:

y = x^2 + 5x + 6 *FACTOR*

(x+2) (x+3) = 0

x + 2 = 0

  -2     -2

x = -2

x + 3 = 0

    -3   -3

x = -3

What type of angle is
mash [69]

Answer:

I'm really sorry I can't tell you the answer because you have to measure the angle by yourself using a protractor. But I gave you information about types of angles if you got the degree of angles ( e.g 90 degrees). Hope it helped.

Step-by-step explanation:

acute angle-an angle between 0 and 90 degrees  

right angle-an 90 degree angle  

obtuse angle-an angle between 90 and 180 degrees  

straight angle-a 180 degree angle

tamaranim1 [39]
<h3><u>Answer</u>:- </h3>

\longrightarrow \sf 75+ 30(h-1)

<h3><u>Solution:-</u></h3>

<u>Given </u><u>that </u><u>:</u><u>-</u>

  • job last for h hours
  • Cost of job lasting more than 1 hour = $30
  • Cost for the first hour = $75

\leadstoRemaining hours for which the job will last after first hour= (h-1)

<u>Therefore</u>,

Cost for subsequent hours = 30×(h-1)

= 30(h-1)

Total Cost for job = Cost for 1st hour + Cost for subsequent hours

\quad\quad\quad\quad\quad\quad\quad\quad\boxed{\sf{= 75+30(h-1)}}

Answer:

a) yes

b) 2560

Step-by-step explanation:

An exponential function has a common ratio between points uniformly spaced. Here, the data points are 10 years apart.

The ratio of the first two values is 4000/5000 = 0.8.

The ratio of the next two values is 3200/4000 = 0.8.

These ratios are the same, so the data is consistent with an exponential function.

The common ratio can be used to predict the next value. The next value is predicted to be ...

  3200 × 0.8 = 2560

Can you help me to solve this problem
storchak [24]

Answer:

I want to show you how to do this as well, the formula you are working with is a^2+b^2=c^2

Step-by-step explanation:

1.) 8^2+b^2=12^2

64+b^2=144

subtract 64 from both sides

b^2=80

take the square root of 80 and you get

b= 8.9

if you need more help on this let me know, I am going to list the other answers now because to do it all and show work on here is a lot of typing, all of which I will do if you do not understand the first example. Also the c value can ONLY BE THE HYPOTENUSE VALUE. The hypotenuse is the longest side of the triangle. For example, 12 would be the C value on number one and in number two it would be 15.

2.) 14.5

3.) 10.3

4.) 18.8

5.) 8

6.) 15
