☆ The relation between x and y is <u>y</u><u> </u><u>=</u><u> </u><u>a</u><u> </u><u>cos</u><u> </u><u>x°</u><u> </u><u>+</u><u>b</u><u> </u>

Taking 1st condition from the table .

→ x = 0 and y = 9

→ y = a + cos 0° + b

→ 9 = a + cos 0° + b

☆ We know that cos 0° = 1

→ 9 = a(1) + b

<h3>→ a + b = 9. equation 1st </h3>

Now taking other condition

→ x = 90° and y = 1

→ y = a cos 90° + b

→ 1 = a cos 90° + b

☆ We know that cos 90° is 0

→ 1 = a(0) + b

<h3>→ 1 = b </h3>

<u>Putt</u><u>ing</u><u> the</u><u> </u><u>val</u><u>ue</u><u> of</u><u> </u><u>b</u><u> </u><u>in</u><u> </u><u>equation</u><u> </u><u>1</u><u>s</u><u>t</u><u> </u><u>.</u><u> </u>

→ 9 = a + 1

→ <u>a</u><u> </u><u>=</u><u> </u><u>8</u><u> </u><u>.</u><u> </u>

<u>Now</u><u> </u><u>taki</u><u>ng</u><u> the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>acc</u><u>ording</u><u> to</u><u> the</u><u> </u><u>ques</u><u>tion</u><u> </u><u>.</u>

☆ x = 45 °

→ y = 8 ( cos 45°) + 1

☆ We know that cos 45° is 1/√2

→ y = 8(1/√2) + 1

→ 8 = 4×√2×√2

<h3>y = 4√2 +1 </h3>

So the answer is <u>4</u><u>√</u><u>2</u><u>+</u><u>1</u><u> </u>

Suppose you pay $1.00 to roll a fair die with the understanding you will get $3.00 back rolling a 4 or a 2, and nothing otherwis
Evgesh-ka [11]
On the presumption that it is a cubic die, on average you will not gain nor lose any money. Out of the six faces, 1/3 of them are a 5 or a 2. So 1/3 of the time, you will gain 3$, but will lose 1$ from the initial payment. 1/3 of 3$ is 1$, so on average, you will gain 1$, while losing 1$.
Another way of looking at it is to take the possible out comes, and add the gains/loses, and you will come up with 0$.

What is the answer i'll give brainly
egoroff_w [7]

Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

4(-2)=4*\frac{-c-11}{4}

Cancel multiplied terms that are in the denominator

4(-2)=-c-11

Multiply the numbers

-8=-c-11

Add 11 to both sides of the equation

-8+11=-c-11+11

Simplify

3=-c

Divide both sides of the equation by the same term

\frac{3}{-1}=\frac{-c}{-1}

Simplify

c=-3
