slope = - 1

Step-by-step explanation:

calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = A (0, 2 ) and (x₂, y₂ ) = B (2, 0 )

m = \(\frac{0-2}{2-0}\)  = \(\frac{-2}{2}\) = - 1

The perimeter of one of those six squares formed is 24 inches.

The rectangle measures 12 inches by 18 inches.

The rectangle is cut into six identical square by making three cut.

Therefore, let's find the area of the rectangle:

The square formed are 6 in numbers. Therefore,

6l² = 216

l² = 216 / 6

l = √36

l = 6 inches

The length of each square formed is 6 inches.

Answer: 795

Step-by-step explanation:

75 + (210 x 3) + (30 x 3) = 795

Ok, so the question is based on geometric progression. Remember, the formula for calculating the nth-term of a geometric progression is: \(a*r^{n-1}\). The a in the expression stands for the 1st term of the sequence, and r is the common ratio of the elements of the sequence. Now let's take a look at the problem.

"A ping pong ball has a 75% rebound ration". We can infer that our common ratio, r, is 75% which is 0.75.

"When you drop it from a height of k feet...", this means the first height you drop it from, a.k.a, the first term.

Now going back to the expression, the nth-term = \(a*r^{n-1}\), we can substitute our common ration, 0.75 with r, and our 1st term, k, with a. This becomes: \(k * 0.75^{n-1}\). This becomes our expression.

a. The highest height achieved by the ball after six bounces. Our nth-term here is 6, so let's use our expression to find the 6th term. \(n_{6} = 235 * 0.75^{6-1} = 235*0.75^{5} = 235*0.2373 = 55.7655ft\)

b. The total distance travelled by the ball when it strikes the ground for the 12th time. This involves the use of the sum of elements in the geometric progression. The formula for that is \(\frac{a(1 - r^{n})}{1-r}\), provided that r is less than 1, which it is in this case, since 0.75 is less than one. Our nth-term here is 12, so we substitute.

\(\frac{235(1-0.75^{12})}{(1-0.75)} = 910.2242ft\)

Proportional and linear functions are very similar. The only difference is the addition of the “​b​” constant to the linear function. A proportional relationship is just a linear relationship where ​B​ = 0, or where the line passes through the origin (0, 0).

Answer:

Step-by-step explanation:

π as a value is \(\frac{22}{7}\). Expresssing \(\frac{22}{7}\) as decimal will give;

π = \(\frac{22}{7}\) = 3.142857 142857 142857 1...

It can be seen that the values after the decimal point goes indefinitely by continually imputing the value 142857 based on the segregation. Therefore an expansion to 5dp is the only approximate value for π since the remaining values are mere repetition.

Converting to 5 decimal places means having just 5 values after the decimal point as shown;

\(\pi = \frac{22}{7} = 3.14286\)

The last value is rounded up to 6 because the succeeding value is 7(which is more than 5). In this case 1 will be added to the fifth place value in the figure rounding it up to 6.

The true statements about the polynomial function graphed are:

Its leading coefficient is positive.

It has an odd degree.

None of the zeroes have even multiplicity.

From the given options, the true statements about the polynomial function graphed are:

Its leading coefficient is positive.

It has an odd degree.

None of the zeroes have even multiplicity.

Let's analyze each statement:

Its leading coefficient is positive:

The leading coefficient of a polynomial is the coefficient of the term with the highest degree.

From the graph, if the polynomial is going upwards on the right side, it indicates that the leading coefficient is positive.

It has an odd degree: The degree of a polynomial is the highest power of the variable in the polynomial expression.

If the graph has an odd number of "turns" or "bumps," it indicates that the polynomial has an odd degree.

None of the zeroes have even multiplicity:

The multiplicity of a zero refers to the number of times it appears as a factor in the polynomial.

In the given graph, if there are no repeated x-intercepts or no points where the graph touches and stays on the x-axis, it implies that none of the zeroes have even multiplicity.

The other statements (its leading coefficient is negative, it has an even degree, it has exactly two real zeroes, it has exactly three real zeroes, and none of the zeroes have odd multiplicity) cannot be determined based solely on the information given.

Therefore, the true statements about the polynomial function graphed are:

Its leading coefficient is positive.

It has an odd degree.

None of the zeroes have even multiplicity.

Step-by-step explanation:

You want to know the 15% down payment, the mortgage amount, the value of 1 point, and the total interest cost for a 6.5% 30 year loan on a $210,000 home.

The answer choices all have the down payment as $31,500 and the loan value as $178,500. A "point" is one percent of the loan value (not the home value), so ...

  1 point = 0.01 × $178,500 = $1785 . . . . . . eliminates choices A and C

The difference between choices B and D is in the value of the interest paid. Your experience with 30-year loans in this interest rate range tells you that the interest paid is between 1 and 2 times the loan value. That is, the chice $227,667 is more likely correct than the choice $406,167.

Comparing these two numbers, we see they differ by 178,500, which is the value of the loan. That is, we can guess that 406,167 is the total amount repaid, not just the interest.

Answer choice B is the only one that makes sense.

If you like, you can work the problem.

  down payment = 15% × $210,000 = $31,500

  loan amount = $210,000 -31,500 = $178,500

  one point = 0.01 × $178,500 = $1785

The monthly payment is found using the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

  A = 178500(0.065/12)/(1 -(1 +0.065/12)^(-12·30)) ≈ 1128.24

The monthly payment amount is about $1128.

So, the total repaid is 360 payments of $1128.24, or $406,167.

The interest paid is this amount less the principal:

  interest paid = $406,167 -178,500 = $227,667

The equation of line containing vertices (8,4) is y = 4.

Y = mx+b, where m is the slope and b is the y-intercept, is the formula for the slope-intercept form (the point where the line crosses the y-axis). Using y=mx+b to graph a line is typically simple. The standard form and the point-slope form are other formats for linear equations.

Equation of line in slope - intercept form is

y = mx + c

where m= slope

c = y - intercept

As it is given that equation of line is horizontal,

this implies

x = 0

y = m (0) + c

y = c

Now, the given coordinates are (8,4)

Slope of the equation equals 0 As the line is horizontal.

⇒ y = 0 (8) + 4

⇒ y = 4

Example 2: x = 3.2

Example 3: x = 23.5

Example 4: x = 9.3

From the question we are to determine the value of the missing sides in the given triangles

We can determine the value of the missing sides by using SOH CAH TOA

Example 1

Angle = 42°

Opposite side = x

Hypotenuse = 25

Thus,

sin (42°) = x / 25

x = 25 × sin (42°)

x = 16.7

Example 2

Angle = 75°

Opposite side = 12

Adjacent side = x

Thus,

tan (75°) = 12 / x

x = 12 / tan (75°)

x = 3.2

Example 3

Angle = 36°

Hypotenuse side = x

Adjacent side = 19

Thus,

cos (36°) = 19 / x

x = 19 / cos (36°)

x = 23.5

Example 4

Angle = 53°

Opposite side = x

Adjacent side = 7

Thus,

tan (53°) = x / 7

x = 7 × tan (53°)

x = 9.3

Hence,

The missing sides are 16.7, 3.2, 23.5 and 9.3
