For question number 5

The area of the circular pateo is 50.24 square yards.

Remember that for a circle of radius R, the area is given by the formula:

A = pi*R²

Where pi = 3.14

Here we know that the patio is circular, and it has a diameter of 4 yards, then the radius is:

R = 4yd/2

R = 2 yd

Replacing that in the area formula we will get:

A = 3.14*(2yd)²

A = 50.24 yd²

The rate at which the temperature of the compound rose was 5¹/₄ degrees per hour.

To find the rate at which the temperature of the compound rose, we need to divide the change in temperature by the time interval during which the change occurred.

The temperature rose 3¹/₂ degrees every 2/3 of an hour. To write this as a fraction, we can first convert 3¹/₂ to an improper fraction:

3¹/₂= 7/2

Now, we can write the rate of change as a fraction:

Rate of change = (7/2) / (2/3)

To divide by a fraction, we can multiply by its reciprocal:

Rate of change = (7/2) x (3/2)

Simplifying, we get:

Rate of change = 21/4

Therefore, the rate at which the temperature of the compound rose was 5¹/₄ degrees per hour.

Answer:

Step-by-step explanation:

The correct statement regarding whether the graph represents a function is given as follows:

No, it is not a function.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

In the graph, we have that at x = 0 = y-axis, the function has three numeric values, which is a case of vertically aligned points, hence the graph does not represent a function.

Answer:

Step-by-step explanation:

You want the number of day passes sold for $61 and weekend passes sold for $110 if 257 more day passes were sold, and sales totaled $307745.

Let w represent the number of weekend passes sold. Then w+257 is the number of day passes sold. The total revenue is ...

  61(w+257) +110(w) = 307745

Simplifying the equation, we have ...

  171w +15677 = 307745

Step-by-step explanation:We can solve this quadratic equation in cos(θ) by using the substitution u = cos(θ):

5u^2 - 8u + 2 = 0

We can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 5, b = -8, and c = 2. Substituting these values, we get:

u = (8 ± sqrt(64 - 40)) / 10

u = (8 ± 2sqrt(6)) / 10

John should mark the bike at $390 to offer a 10% discount and still make a 30% profit on the price he paid for.

If John wants to make a 30% profit on the price he paid for the bike, he needs to sell it for:

$270 + 30% of $270 = $270 + $81 = $351

To offer a 10% discount on the marked price, he needs to calculate the price that includes the discount. Let's call this price "x".

90% of the marked price "x" is the same as the price he wants to sell the bike for ($351):

0.9x = $351

x = $390

Answer:

n = -5

Step-by-step explanation:

We know that when two lines are perpendicular, the slopes of the two lines are negative reciprocals as

[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the line we're usually not given, and m1 is the slope of the line we're given

Thus, we know that m2 must equal -1/2 from the formula since m1 is 2:

[tex]m_{2}=-\frac{1}{2}[/tex]

Of course, -1/2 is already simplified so m2 is the slope of the line passing through (8, n) and (2, -2)

To find n, we must use our knowledge of the slope formula that gives us the slope, m:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one point on the line and x2 and y2 are another point on the line:

If we allow (8, n) to be our x1 and y1 point and allow (2, -2) to be our x1 and y2 point and -1/2 to be our m, we can now solve for m by plugging everything into the slope formula and solving for n (aka y1 in the formula:

[tex]-1/2=\frac{-2-n}{2-8}\\ \\-1/2=\frac{-2-n}{-6}\\ \\3=-2-n\\\\5=-n\\\\-5=n[/tex]

We can even check that we get -1/2 when we plug in -5 into the slope formula:

[tex]-1/2=(-2-(-5))/(2-8)\\-1/2=(-2+5)/(-6)\\-1/2=3/-6\\-1/2=-1/2[/tex]

The value of SV, given that point J is the centroid, would be A. 9.

Seeing as we have point J as the centroid for triangle SZU, we can then tell that JV would be:

JV = 1 / 3 x SV

Knowing this, we can make SV the subject of the formula to become:

(JV = 1 / 3 x SV ) / 1 / 3

3 x JV = SV

SV = 3 JV

SV would then be:

SV = 3 x JV

SV = 3 x 3

SV = 9

The Height of the given rectangular prism is:  (x + 1) - 4/(x³ + 3x² + 8)

In algebra, polynomial long division is defined as an algorithm used in dividing a polynomial by another particular polynomial of the same or even lower degree, which is a generalized version of the common arithmetic technique called long division. It can be done easily by hand, because it separates a supposedly complex division problem into smaller ones.

We are given:

Volume of a rectangular prism =  (x⁴ + 4x³ + 3x² + 8x + 4), and the area of its base is (x³ + 3x² + 8)

Thus, height is:

                   x + 1

x³ + 3x² + 8|x⁴ + 4x³ + 3x² + 8x + 4

                -  x⁴ + 3x³ + 0   + 8x

Density is calculated by dividing the mass of an object by its volume. In this case, the density of the foam cube is 62 g / 125 cubic inches = 0.496 g/cubic inch.

So, the volume of the foam cube is 125 cubic inches and its density is 0.496 g/cubic inch.

Answer: The total sum of all monthly payments required to pay off this loan is $410,932.

To calculate this, we need to first find the amount of the loan that is not covered by the deposit. The deposit is 20% of $300,000, or $60,000, so the remaining amount of the loan is $300,000 - $60,000 = $240,000.

Next, we need to calculate the monthly payment on the loan. We can use the formula for a fixed-payment loan to do this:

Payment = (Loan amount x Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Number of months))

The monthly interest rate is the annual interest rate divided by 12, or 0.0394 / 12 = 0.003283.

The number of months is the number of years times 12, or 30 x 12 = 360.

Plugging these values into the formula gives:

Payment = ($247,249 x 0.003283) / (1 - (1 + 0.003283)^(-360)) = $1,151.80

Finally, we can find the total sum of all monthly payments by multiplying the monthly payment by the number of months:

Total payments = $1,151.80 x 360 = $410,932 (rounded to the nearest whole number).

Step-by-step explanation:

The two expressions "8m+4-3m" and "3+ m+2m+1+2m​" are equivalent because they simplify to the same-value.

To determine if the two expressions are equivalent, we can simplify each expression and then compare them.

Simplifying the first -expression,

We have,

⇒ 8m + 4 - 3m can be simplified by combining like terms;

⇒ 8m - 3m + 4 = 5m + 4

Next, Simplifying the second-expression,

we have,

⇒ 3 + m + 2m + 1 + 2m can also be simplified by combining like-terms:

⇒ (1 + 3) + (m + 2m + 2m) = 4 + 5m

So we have:

(i) 8m + 4 - 3m = 5m + 4

(ii) 3 + m + 2m + 1 + 2m = 4 + 5m

Since both simplified expressions are equal to "5m + 4", we can conclude that the two original expressions are equivalent.

An equation to represent A, the area in square feet, as a function of w, the width in feet is A = 120W -2W²

Here, we have,

According to the question, the school uses 120 feet of fencing material to enclose three sides of the play area. This means there are 3 sides.

Substitute into the perimeter of the rectangle will give:

120 = L + 2W

Area = LW

We know that the area of a rectangle is l × w

When w =10, length = 120 - 20 = 100, area = 100 x 10 = 1000

When w = 20, length = 120 - 40 = 80,  area =  80 x 20  = 1600

When w = 40, length = 120 - 80 = 40.  area = 40 x 40 = 1600.

So, the completed table will be

Width            Length          Area

10                    100              1000

20                    80              1600

40                    40              1600  

w                  120 - 2w        (120 - 2w) w

In order to maximize the area with the given fencing, from the equation written above, then w = 30 feet and l = 60

On substituting, we have;

A = LW = (120 - 2W) W

L = 120 - 2W,

On simplification, we have

A = 120W -2W²

18. The end behavior of the graph of f(x) = x³ + 2x² - 5x + 1 is as follows: as x approaches negative infinity, the function f(x) approaches negative infinity, and as x approaches positive infinity, the function f(x) approaches positive infinity. This is because the leading term of the polynomial is x³, which has a positive coefficient, so the graph of the function will have a "smile" shape, with the ends of the graph pointing upwards.

19. The end behavior of the graph of g(x) = -2x³ - 8x² + 18x + 72 is as follows: as x approaches negative infinity, the function g(x) approaches negative infinity, and as x approaches positive infinity, the function g(x) approaches negative infinity.

7)   θ = 60°

We can see a right triangle where we want to find the value of θ, we know the hypotenuse and the opposite cathetus, then we can use the trigonometric relation:

sin(θ) = (opp cath)/hyp

Replacing what we know:

sin(θ) = 6/12 = 1/2

The formula for p(x) is p(x) = -0.1(x - 5)²(x + 3).

In Mathematics and Geometry, the graph of a polynomial function touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.

Also, the graph has a zero of multiplicity 2 at x = 5 and zero of multiplicity 1 at x = -3;

x = 5 ⇒ x - 5 = 0.
