Solve for y,if 3+3y=1–13y

Answers

Answer 1

Step 1: Simplify both sides of the equation.

3+3y=1−13y−9

3+3y=1+−13y+−9

3y+3=(−13y)+(1+−9)(Combine Like Terms)

3y+3=−13y+−8

3y+3=−13y−8

Step 2: Add 13y to both sides.

3y+3+13y=−13y−8+13y

16y+3=−8

Step 3: Subtract 3 from both sides.

16y+3−3=−8−3

16y=−11

Step 4: Divide both sides by 16.

16y

16=−11/16

y=−11/16

Answer:

y=−11/16

COS(α+β); SINα=- 1/3, α IN QUADRANT IV, TANβ=7/3, β IN QUADRANT III

PLEASE, I HAVE BEEN TRYING TO FIND THE ANSWER FOR 3 HOURS, AND I HAVE SPENT LIKE 1000 POINTS

Answers

Recall the angle sum identity for cosine,

cos(α + β) = cos(α) cos(β) - sin(α) sin(β)

Then given sin(α) = -1/3, we have

cos(α + β) = cos(α) cos(β) + 1/3 sin(β)

α is in quadrant IV, so 3π/2 < α < 2π, and so sin(α) is negative and cos(α) is positive. Then from the Pythagorean identity, we get

sin²(α) + cos²(α) = 1

⇒   cos(α) = √(1 - sin²(α)) = 2√2/3

β is in quadrant III, so π < β < 3π/2, so both sin(β) and cos(β) are negative. If we multiply both sides of the previous identity by 1/cos²(α) and replace α with β, we get

sin²(β)/cos²(β) + cos²(β)/cos²(β) = 1/cos²(β)

⇒   tan²(β) + 1 = 1/cos²(β)

⇒   1/cos(β) = -√(tan²(β) + 1) = -√58/3

⇒   cos(β) = -3/√58

Also recall that by definition,

tan(β) = sin(β)/cos(β)

⇒   sin(β) = tan(β) cos(β) = 7/3 • (-3/√58) = -7/√58

Putting everything together, we find that

cos(α + β) = 2√2/3 • (-3/√58) + 1/3 • (-7/√58) = -(6√2 + 7)/(3√58)

or more clearly,

[tex]\cos(\alpha + \beta) = -\dfrac{6\sqrt2 + 7}{3\sqrt{58}}[/tex]

What are the roots of the equation 4x^2+24x+45=0 in simplest a+bi form?

Answers

Answer:

X=(-1.5, 7.5)

Step-by-step explanation:

Simplifying

4x2 + -24x + -45 = 0

Reorder the terms:

-45 + -24x + 4x2 = 0

Solving

-45 + -24x + 4x2 = 0

Solving for variable 'x'.

Factor a trinomial.

(-3 + -2x)(15 + -2x) = 0

 

Set the factor '(-3 + -2x)' equal to zero and attempt to solve:

Simplifying

-3 + -2x = 0

Solving

-3 + -2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + -2x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + -2x = 0 + 3

-2x = 0 + 3

Combine like terms: 0 + 3 = 3

-2x = 3

Divide each side by '-2'.

x = -1.5

Simplifying

x = -1.5  

Set the factor '(15 + -2x)' equal to zero and attempt to solve:

Simplifying

15 + -2x = 0

Solving

15 + -2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + -2x = 0 + -15

Combine like terms: 15 + -15 = 0

0 + -2x = 0 + -15

-2x = 0 + -15

Combine like terms: 0 + -15 = -15

-2x = -15

Divide each side by '-2'.

x = 7.5

Simplifying

x = 7.5

Solution

x = {-1.5, 7.5}

y=3x+1

Step-by-step explanation:

The question is asking for an equation in slope-intercept form. This is y=mx+b, where m is slope and b is y-intercept. The slope is the change is y over the change in x. The y value changes 3 and the x value changes 1. So, the slope is 3/1 or just 3. The y-intercept is the value where the line intersects with the y-axis. Additionally, the y-intercept will have an x-value of 0. On the table, you can see that y=1 when x=0. Thus, the y-intercept is 1. Put the two values into the equation and you get y=3x+1.

Adult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score
of a man 72.4 inches tall. (to 2 decimal places)

Answers

Answer:  1.21

Work Shown:

z = (x - mu)/sigma

z = (72.4 - 69.0)/(2.8)

z = (3.4)/(2.8)

z = 1.2142857 .... which is approximate

z = 1.21

Z-score of a man who is 72.4 inches tall is 0.45.

Understanding the concept of the z-score helps us gauge how far a value is from the mean in terms of standard deviations.

A z-score, denoted as , measures the deviation of a data point from the mean in terms of standard deviations. It's calculated using the formula:

= ( - ) /

Where:

- is the value we want to find the z-score for (72.4 inches in this case).

- is the mean of the dataset (69.0 inches).

- is the standard deviation of the dataset (2.8 inches).

Plugging in the values:

= (72.4 - 69.0) / 2.8 = 1.25 / 2.8 ≈ 0.446

Rounded to two decimal places, the z-score is approximately 0.45.

This means that a man who is 72.4 inches tall is roughly 0.45 standard deviations above the mean height of adult men.

In other words, his height is a bit taller than the average height by about 0.45 times the standard deviation.

This positive value indicates that the man's height is above the mean. If the z-score were negative, it would mean the height is below the mean. By using z-scores, we can compare data points from different distributions and understand how unusual or typical a particular value is within its dataset.

Z-scores help us quantify the relative position of a data point, providing a standardized way to interpret its significance in the context of the dataset's characteristics.

In summary, the z-score of a man who is 72.4 inches tall is approximately 0.45, indicating that his height is slightly above the average height of adult men.

Explanation

As for this specific question algebra is something I do in my head and skip many steps for however if you want to proof my answer it would be this.

-0.25-16*.25=-0.25-4

-0.25-4=-0.25-4

-4.25=-4.25

For the function  f(x) = -x-4 the value of f(4) is -8.

The given function is f(x) = -x-4.

We need to find the value of f(4).

To find this we have to replace the x value with 4.

Substitute x=4 in the function:

f(4)=-4-4

f(4)=-8

Hence, the value of f(4) is -8.

Express 2x2 + 16x +11 in the form a (x + b)2 + c, where a, b and c are
numbers.
What are the values of a, b and c?

Answers

Step-by-step explanation:

I assume the original expression is

2x² + 16x + 11

we need to get this into the form of a(x + b)² + c

let's do the generic multiplication and compare the result to the given expression :

a(x² + 2bx + b²) + c = ax² + 2abx + ab² + c

when we compare this with the original equation, we only need to look at terms with the same variable exponents.

2x² is the only term with "x²".

and ax² is the only term with "x²" in the generic form.

so ?

2x² = ax²

=>

a = 2

16x is the only term with "x" (exponent 1).

2abx is the only term with "x" in the generic form.

16x = 2abx

8x = abx = 2bx

4x = bx

=>

b = 4

11 is the only pure number (constant).

ab² + c is the only constant term in the genetic form.

11 = ab² + c = 2×4² + c = 2×16 + c = 32 + c

-21 = c

so, the solution is

2(x + 4)² - 21

We arrived at the hospital, and then a doctor examined her right away. He wanted to know if she may have had a heart attack, so he ran an EKG exam which checks for heart problems. Then the doctor left the room, and we both waited for the test results. I scooted closer to Mom on the hospital bed and leaned my head against her shoulder. "When do you think the doctor will come back?" I asked. My stomach gurgled. Mom chuckled. "Jennifer, are you asking because you're concerned about me or because you're famished? I think your stomach is growling loud enough to page the doctor over the loudspeaker." I laughed. "I'm concerned about you." Then, in a more serious tone, I added, "You're the only family I have. Does your chest still hurt?" "A little bit, but I'm not so scared anymore." I sighed with relief. The doctor, carrying a clipboard, walked into the room. "Mrs. Harper, I have the results from your EKG," he declared with a smile. "You did not have a heart attack." "That's good news," Mom said. "What do I have, then?" "Well, I'd like to ask you a few questions so that we can determine what's going on," the doctor said gently. "Do you have a headache? Do you have pain in your extremities?" Mom shrugged her shoulders. "My head hurts a little bit, but I think that's because I haven't had my morning coffee yet. My hands and feet are fine." "Do you have any pain anywhere else?" the doctor asked. "No, sir," Mom replied. "Do you have heart disease or diabetes in your family history?" the doctor continued. "No," Mom said. The doctor looked at his clipboard and, deep in thought, scratched his mustache. "Do you exercise regularly? How much water do you usually drink?" Mom chuckled nervously and answered, "I don't have time to exercise." "She doesn't drink water," I told the doctor. "She drinks coffee." The doctor stopped scratching his mustache, and he glared at Mom. "How much coffee do you drink per day?" "Oh, just three thermoses full," Mom replied, gesturing with her hands that her thermos was about a foot tall. "At least," I added. The doctor rolled his eyes and exhaled. "That's not good," he said. "Drinking more caffeine than water is never good. Mrs. Harper, I believe you simply have costochondritis. That's inflammation of the chest wall. It's temporary, and you can relieve the pain with ibuprofen. You'll also want to start drinking plenty of water instead of coffee." Mom blushed with embarrassment. "You mean that I just had the biggest scare of my life because I've been drinking too much coffee?" "I believe so, yes," the doctor replied with a grin. "However, if your pain persists, please come back in, and we can do further tests. But for now, we'll unhook you from that machine and send you home, all right?" Mom looked at her watch. "Wow.
