Hey there!

=> y= 16x^2 + 64 +5

Let's obtain a formula for x

=> y= 16x^2 + 64 +5

=> y=16x^2+69

=> y - 69 = 16x^2

=> y - 69/16 = x^2

=> y - 4.3125 = x^2

=> x = √y - 4.3125

=> x = y - 2.08

Answer:

  about 14 months

Step-by-step explanation:

Questions regarding loan payments, values, interest amounts, number of payments, and so on, are conveniently answered by the financial formulas available in many apps, calculators, and spreadsheets. Here, we want to solve for the number of payments.

__

The time-value-of-money app on a TI-84 calculator tells us the number of monthly payments is 13.98. It will take about 14 months to pay off the credit card balance.

__

Alternate solutions

You can also use a graphing calculator to find the time value needed in the amortization formula that corresponds to a monthly payment amount of $300 on a loan of $3850 at 13.99% interest compounded 12 times per year. This is shown in the second attachment.

The algebraic solution is a little messy, and involves logarithms, but you can solve it that way, too.

  A = P(r/n)/(1 -(1 +r/n)^(-nt))

gives the monthly payment A on a loan of principal P at annual rate r compounded n times per year for t years. We want to find the value of nt for P=3850, A=300, r=0.1399, n=12.

Putting in the numbers, we get ...

  300 = 3850(0.1399/12)/(1 -(1 +0.1399/12)^(-nt))

  (1.011658333...)^(-nt) = 0.8503847222... . . . . isolate nt term

  nt = -log(0.8503857222...)/log(1.011658333...) ≈ 13.982213...

The third angle measures 50° and all sides have different lengths.

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled.

The sum of angles in a triangle is 180 degrees.

A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:

x + 100 + 30 = 180° (sum of angles in a triangle)

x = 50°

Also, all sides have different lengths since all the angles are different.

The third angle measures 50°.

The third angle measures 50°.

4x-40+104 = 180

4x+144 = 180

subtract 144 from both sides

4x = 36

divide both sides by 4

The missing value in the given perfect square trinomial is 20. (option 2)

A perfect square trinomial is a trinomial that can be written as the square of a binomial.

Given that, Tia wrote a perfect square trinomial on the board, but a value is missing.

The trinomial is =

4x²+?+25

When comparing with (a+b)² = a²+b²+2ab

We get,

a² = 4x²

a = 2x

b² = 25

b = 5

We are asked to find, 2ab,

Therefore,

2ab = 2×2x×5

= 20x

Hence, the missing value in the given perfect square trinomial is 20.

Answer: 412.5cm cubed

Step-by-step explanation:

Volume of a prism: area of base ( in this case it’s the triangle) times the height

First: half x 90 x 120 = 165

Then times the height

So, 164 x 2.5 = 412.5

The volume of the given pyramid will be 1.35m³.

Design or construction with a base that is a polygon and sides that are three or more triangles that come together at the top.

A pyramid is a 3D shape where 3 triangle comes and meet in such a way that the base side creates a triangle.

The volume of a pyramid is given by

Volume = (1/3)base²×height.

Volume = area of cross-section × length

Given,

Area of cross-section = area of the base (triangle)

Since the area of the triangle = (1/2)base×height

So,

Area of cross-section = (1/2)1.20×0.90 = 0.54 m²

So,

Volume of pyramid = 0.54 × 2.5 = 1.35 m³.

Hence " The volume of the given pyramid will be 1.35m³".

Answer:

The number of situps is approximately 19

Step-by-step explanation:

Regression Line

A regression line is a line that best fits any given dataset in terms of having the smallest overall distance from the line to the points.

Regression lines are useful to forecast the behavior of the dependent variable.

We are given the statistics related to determining if there is a relationship between hours of TV watched per day (x) and the number of situps a person can do (y).

The line is given as follows:

y=-0.761x+20.501

The rest of the parameters can only be used as a reference to evaluate how good the line approaches the dataset.

Now use the line to predict the number of situps a person who watches x=2 hours of TV can do:

y=-0.761*2+20.501

y=19

The number of situps is approximately 19

Answer:

the answer is undefined

Step-by-step explanation:

If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

Step-by-step explanation:

↓ Define Prime number ↓

Prime number ⇒ A positive integer that has no positive integer divisors other than 1 and itself. To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number.

Solve:

76 is not a prime number. The number 76 is divisible by 1, 2, 4, 19, 38, 76.

79 is a prime number. The number 79 is divisible only by 1 and the number itself.

100 is not a prime number. The number 100 is divisible by 1, 2, 4, 5, 10, 20, 25, 50, 100.

66 is not a prime number. The number 66 is divisible by 1, 2, 3, 6, 11, 22, 33, 66.
