Answer:

x=13 degrees

Step-by-step explanation:

Since m is parallel to l, 119= (9x+2)

119=9x+2

Subtract 2

117=9x

Divide by 9

13=x

omg i swear PLEASE someone actually explain the answer to me, i need help & im desperate. ill give brainliest to whoever exp
Radda [10]

Answer:

Part 1: 19° C

Part 2: decay

Part 3: 11%

Don't drop out!! You'll hurt yourself if you do that! If you feel trapped/stuck, reach out for help from friends and teachers and parents. Find someone who can help you understand what you're learning and teach you. Study extra if you need to. But don't drop out.

Step-by-step explanation:

You've got the initial temperature down: the constant that the function multiplies is the initial condition/number/temperature/population/&tc. since that constant is 19, the initial temperature is 19° C.

However, this is not an exponential <em>growth</em> function. This is an exponential <em>decay</em> function. There are two ways to surmise this:

  1. The context of the problem is a soda can placed in a cooler. The temperature will <em>decrease</em>, right? This means the function is an <em>exponential decay function</em>.
  2. If the function given were an exponential <em>growth</em> function, then the number within parentheses (this is the percentage by which something changes) would be greater than 1. It isn't, and so the function is an exponential <em>decay</em> function

As for the percentage at which it is changing… erm, <em>decreasing</em>… that would be 100 times the difference of <em>1 – r</em>. Here, <em>r</em> is the number in parentheses. First, let's solve for 1 – <em>r</em>. Here, <em>r</em> is 0.89, so 1 – 0.89 = 0.11, and now we just need to multiply by 100. Why?

Percentages are a fraction of 100. For example, 89% is equal to 0.89 and the fraction \frac{89}{100}. Here, we multiply 0.11 to find the percentage of change. So we have 0.11 × 100 = 11%, and our rate of change is 11%. Thanks to breyanamyers5 who indirectly hinted at my mistake here!

I hope this is the explanation you were hoping for! Have a great day, and <em>don't give up</em>!!

Wait a second... this question was <em>3 months old</em>. Whoops. Oh well.

The function y = 4x² + 9x-2 has______at the vertex.<br><br> A:minimum<br> B:Maximum
Sveta_85 [38]

Answer:

  • A. Minimum

Step-by-step explanation:

Given function:

  • y = 4x² + 9x - 2

This is a quadratic function with <u>positive</u> leading coefficient.

It means the graph of the function opens up and therefore it has minimum value of the function at the vertex.

<u>Correct</u> answer <u>choice</u> is A

Andreas93 [3]

Answer:

$3,300

Step-by-step explanation:

The salary given falls in the third range, meaning it should get a 5.5% income tax on the $60,000.

5.5% = 0.055

0.055 * $60,000 = $3,300

Therefore, the state income tax owed on the provided salary is $3,300.
