4.) x > the quantity 4 times b plus 9 all over negative 3

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial [tex]-3x^4+2x^3-x^2+6[/tex] through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial [tex]-3x^4+2x^3-x^2+6[/tex] .

[tex](x+1)(-3x^3)=-3x^4-3x^3[/tex]

We subtract this from the original [tex]-3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6[/tex].

This leaves [tex]5x^3-x^2+6[/tex]. We repeat the step above.

[tex](x+1)(5x^2)=5x^3+5x^2[/tex].

We subtract this from [tex]5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6[/tex]. We repeat the step above.

[tex](x+1)(-6x)=-6x^2-6x[/tex].

We subtract this from [tex]-6x^2-(-6x^2)+0x-(-6x)+6=6x+6[/tex]. We repeat the step above.

[tex](x+1)(6)=-6x+1[/tex].

We subtract this from [tex]6x-(6x)+6-(6)=0[/tex]. There is no remainder. This means (x+1) is a factor.

Answer:

Price $0.75 per ounce of confetti

Step-by-step explanation:

Given the statement: Yuki bought a pound of confetti for $12.

⇒[tex]1 pound = \$ 12[/tex]                 ......[1]

Also, it is given that there are 16 ounces in 1 pound.

⇒ 16 ounces = 1 pound                       .....[2]

To calculate the price, in dollars per ounce of confetti.

From [1] and [2] we have;

[tex]16 ounces = \$12[/tex]

then;

1 ounces =  [tex]\frac{12}{16} = \frac{3}{4} = \$0.75[/tex]

Therefore, the price, in dollars per ounce of confetti is, $0.75  per ounce.

Answer: [tex]\bold{\dfrac{8}{13}}[/tex]

Step-by-step explanation:

Red   or    Face   -  duplicates (both red & face)

[tex]\dfrac{26}{52}[/tex]     +       [tex]\dfrac{12}{52}[/tex]      -     [tex]\dfrac{6}{52}[/tex]

= [tex]\dfrac{32}{52}[/tex]

= [tex]\dfrac{8}{13}[/tex]   simplified

Final answer:

The probability of selecting a red or face card from a standard deck of cards is 8/13. This outcome is more likely than selecting a heart suit face card specifically, which has a probability of 3/52.

Explanation:

The problem can be solved by understanding that the deck has 26 red cards (hearts and diamonds) and 12 face cards (jacks, queens, and kings), with 6 face cards being red. The total number of unique choices that are either red cards or face cards is the number of red cards plus the number of black face cards. This avoids double-counting red face cards.

There are 26 red cards, but we need to exclude the 6 red face cards already counted, and add the 6 black face cards (from clubs and spades), giving us 26 + 6 = 32 unique cards that are either red or face cards. The probability, P, is then 32/52, which simplifies to 8/13.

To compare, the probability of drawing specifically a heart suit face card is 3/52 as there are only 3 face cards (jack, queen, and king) in the heart suit. Comparing probabilities, 8/13 is greater than 3/52, so it is more likely to draw a red or face card than a heart suit face card.

80/100 = 80% by definition of what "percent" means, which is "per 100" or "for every 100"

So 16/20 = 80% meaning 80% of the tomato is water

Note on a calculator, 16/20 = 0.80 which converts to 80% if you move the decimal point 2 spots to the right.

Answer: 2500 meters²

Step-by-step explanation:

Perimeter: 200 = 4w  

             ⇒    50 = w

Area = w²

        = (50)²

        = 2500

The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The perimeter of the rectangle = 2( length + Width)

                                             200 = 2( length + Width)

                                         100 - w = L

The area of the rectangle = length × Width

                                            = w(100 - w)

                                            = (-w)²+ 100w

So,  (-w)²+ 100w where, a = -1 and b = 100

w = -100/2(-1)

w = 50

The area of the rectangle = (-w)²+ 100w

                                            = (-50)²+ 100(50)

                                           = 2500

Thus, The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.

Answer:

The correct answer is 86.

Step-by-step explanation:

Because 82 is only one standard deviation below the mean, then to find the mean, only add 82 + 4 = 86

The mean score for the test is 86.

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

We are given that;

Score=82

Number of tests=4

Now,

We can substitute σ=4 and xi​=82 into the formula. We also know that there is only one data point that satisfies this condition, so we can use N=1.

[tex]\mu = \frac{\sum_{i=1}^{N}(x_i - \mu)^2}{N\sigma^2} + \mu[/tex]

We get:

μ=(82−μ)^2/4^2 ​+μ

Simplifying and solving for μ, we get:

μ=86

Because to know the answer we have to divide 75 by 12 which is 6.25

Answer:  Since 1/3 can't be turned into a decimal, change .5 into 1/2. In order to subtract, the fractions need a common denominator. The least common denominator is 6. So 1/3 turns into 2/6, and 1/2 turns into 3/6. Now you need to take 9 3/6 minus 6 2/6. The answer is 3 1/6 gallons of water.

Step-by-step explanation:

Final answer:

To find the remaining water in Tank A after pouring out 6 1/3 gallons, subtract 6.333 from the tank's total capacity of 9.5 gallons, which leaves 3.167 gallons remaining in the tank.

Explanation:

The question involves determining the remaining quantity of water in a tank after a certain volume has been removed, which is a basic subtraction problem in mathematics. To solve it, subtract the volume of water that was poured out from the total capacity of the tank.

Tank A capacity: 9.5 gallons

Volume of water poured out: 6 1/3 gallons

To perform the subtraction, we first need to convert 1/3 of a gallon into a decimal. A third of a gallon is approximately 0.333 gallons. Adding this to 6 gallons gives us 6.333 gallons.

Now, subtract the volume poured out from the tank's capacity:

9.5 gallons (capacity) - 6.333 gallons (poured out) = 3.167 gallons (remaining in the tank)

Therefore, 3.167 gallons of water are left in the tank.

Explanation:

The medians of a triangle meet up at the centroid in such a way that they cut each other at a ratio of 2:1, meaning that one part of the median is twice as long as the other. In this case, MO is two times longer than OP, so,

OP = 2*MO

1. The slope of the line is 3.

2. The direct variation equation is y = 3x

3. The equation in slope-intercept form is:y = 4

4. The equation in slope-intercept form is y = 2/3x + 1.

5. The equation = −2/3 − 1

6. The equation of the parallel line is y = 5x - 11.

1. Slope of the line:

The slope (m) of the line passing through (-1, 2) and (0, 5) can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

m = (5 - 2) / (0 - (-1))

m = 3 / 1

m = 3

Therefore, the slope of the line is 3.

2. Direct variation equation:

Since y varies directly with x, we can write their relationship as y = kx, where k is the constant of proportionality. We can find k using the given information:

y = 15 when x = 5

15 = k * 5

k = 3

Therefore, the direct variation equation is y = 3x

When x = 9, y = 3 * 9 = 27.

3. Equation in slope-intercept form: First, calculate the slope using the same formula as in question 1:

m = (4 - 4) / (1 - (-3))

m = 0 / 4

m = 0

Since the slope is 0, the line is horizontal. The equation in slope-intercept form is:

y = 4 (constant y-intercept because it passes through (1, 4))

4. Equation in slope-intercept form using point-slope form:

The point-slope form equation is:

y - y1 = m(x - x1)

Plug in the given values:

y - (-1) = 2/3(x - (-3))

y + 1 = 2/3(x + 3)

3y + 3 = 2x + 6

3y = 2x + 3 (subtract 3 from both sides)

y = 2/3x + 1 (divide both sides by 3)

Therefore, the equation in slope-intercept form is y = 2/3x + 1.

5. Writing the equation in standard form:

The equation = −2/3 − 1 is already in standard form (ax + by = c), where a = -2/3, b = 0, and c = -1.

6. Equation of the parallel line:

Since the parallel line has the same slope (5) as the given line, its equation will be of the form y = 5x + b. To find b, plug the point (2, -1) into this equation:

-1 = 5(2) + b

-1 = 10 + b

b = -11

Therefore, the equation of the parallel line is y = 5x - 11.

Answer:

m<Q = 92 degrees

Step-by-step explanation:

Opposite angles of a quadrilateral inscribed in a circle are supplementary.

Angles O and Q are opposite angles, so they are supplementary, so their measures add up to 180 degrees.

m<O + m<Q = 180

2x + 2x + 4 = 180

4x + 4 = 180

4x = 176

x = 44

m<Q = 2x + 4 = 2(44) + 4 = 92

Answer:

Q =92

Step-by-step explanation:

Since the quadrilateral is inscribed in a circle, the opposite angles add to 180 degrees.

<O + <Q = 180

2x+ 2x+4 = 180

4x+4 =180

Subtract 4 from each side

4x= 180-4

4x= 176

Divide by 4

x = 44

Q = 2x+4

Q = 2(44)+4

Q = 88+4

Q = 92

Answer:

c (0,-4)

Step-by-step explanation:

-5x+y = -4

4x - 4y =16

Solve the first equation for y since we are using substitution.

-5x+y = -4

Add 5x to each side

-5x+5x+y = -4+5x

y = 5x-4

Substitute this equation y = 5x-4 into the second equation.

4x -4(5x-4) = 16

Distribute the -4

4x - 4(5x) -4(-4) = 16

4x-20x +16 = 16

Combine like terms

-16x +16 =16

Subtract 16 from each side

-16x+16-16 = 16-16

-16x =0

Divide by -16

x=0

But we still need to find y

y = 5x-4

y = 5(0) -4

y = -4

The subject of the question involves recursion, or constructing a sequence of numbers in a specific way. In Marta's case, her salary can be calculated using a recursive formula that builds upon her previous salary. This formula relies on the concept of numerical patterns and can be represented as follows: f(n) = f(n-1) + 2700; where f(n) is Marta's salary after n years and f(n-1) is her salary the previous year.

At the start, Marta's salary is 24,900, which serves as the base case for our recursive function. Therefore, her income increases by $2700 each year. To get Marta's salary in 4 years, we would use the recursive formula: f(4) = f(3) + 2700 = f(2) + 2700 + 2700 = f(1) + 2700 + 2700 + 2700 = f(0) + 2700 + 2700 + 2700 + 2700 = 24,900 + 4*2700 = 35,500.

 Multiply each side by y

y sin 60 = 5 sqrt(2)

Divide each side by sin 60

y sin 60/ sin 60 = 5 sqrt(2)/ sin 60

y = 5 sqrt(2) / sin 60

y = 5 sqrt(2) / sqrt(3) /2)

y   = 10 sqrt(2)/ sqrt(3)

You cannot leave a sqrt in the denominator

 y=   10 sqrt(2)/ sqrt(3) * sqrt(3)/sqrt(3)

   y= 10 sqrt(6)/3

tan 60 = oppositve/ adjacent

tan 60 = 5 sqrt(2)/ x

Multiply each side by x

x tan 60 = 5 sqrt(2)

Divide by tan 60

x = 5 sqrt(2)/tan 60

x =5 sqrt(2)/sqrt(3)

You cannot leave a sqrt in the denominator

x = 5 sqrt(2)/sqrt(3) * sqrt(3)/sqrt(3)
