Answer:

the actual hourly percent increase is 6.823 %

Step-by-step explanation:

Given that data in the question;

rate chemical decomposes increasing continuously at 6.6 %,

r = 6.6% = 0.066

actual hourly percent increase = ?

Now,

hourly percent increase = ( \(e^r\) - 1 ) × 100%

we substitute

hourly percent increase = ( \(e^{0.066\) - 1 ) × 100%

hourly percent increase = ( 1.06823 - 1 ) × 100%

hourly percent increase = 0.06823 × 100%

hourly percent increase = 6.823 %

Therefore, the actual hourly percent increase is 6.823 %

Answer:

9

Step-by-step explanation:

The \(n\)term is \(2n+1\).

\(S_n=\frac{3+2n+1}{2}(n)=99 \\ \\ \frac{n(2n+4)}{2}=99 \\ \\ n(n+2)=99 \\ \\ n^2+2n-99=0 \\ \\ (n+11)(n-9)=0 \\ \\ n=9 \text{ } (n>0)\)

The number of terms that needed to make the sum to 99 is 9

The first term of the arithmetic progression = 3

The common difference = 2

The sum of n term is = (n/2) [2a+(n-1)d]

Where a is the initial term

d is the common difference

Substitute the values in the equation

(n/2) [2(3)+(n-1)2] = 99

(n/2) [6 + 2n - 2] = 99

(n/2)[4+2n] = 99

n(2 + n) = 99

2n + \(n^2\) = 99

\(n^2\) + 2n - 99 = 0

Split the terms

\(n^2\) - 9n +11n - 99 =0

n(n -9) + 11(n - 9) = 0

(n + 11)(n - 9) = 0

n = -11 or 9

Since n cannot be a negative number, therefore n = 9

Hence, the number of terms that needed to make the sum to 99 is 9

Answer:

56 minutes

Step-by-step explanation:

We can use proportions to solve.

6 miles            8 miles

------------     = ------------------

42 minutes        x minutes

Using cross products.

6x = 42 *8

Divide each side by 6

x = 42/6 * 8

x = 7*8

x = 56

If he wants an average of 84, he needs to get at least 93 points.

Remember that the average value between 3 values A, B, and C is:

(A + B + C)/3

Here we know that the first two scores are 76 and 83 points, let's say that the third score is x, if we want to have an average of 84 or more, then we need to solve:

(76 + 83 + x)/3 = 84

159 + x = 252

x = 252 - 159

x = 93

So he needs to get at least 93 points in the next exam.

STEP 1: Identify and Set-Up

We are given the equation of the parabola in the polynomial. However, there exists a vertex form through which we can obtain the coordinates of our vertex. The solution of the quadratic equation gives us the x intercepts.

The general equation of a parabola in vertex form is:

where the coordinates of the vertex is (h, k).

STEP 2: Execute

We will now resolve the polynomial and solve it.

Therefore, our vertex is at (1, -4)

Solving our equation,

The x intercepts are x = -1 and x = 3

These points are depicted in the graph as seen above.

The perimeter of Max's sandbox is 21 feet.

The sum of each length of external sides or boundary of a given figure is called its perimeter. To determine the perimeter of an object, add up the length of its boundaries.

Given the dimension of the Ohio park, then we have to determine the representative fraction of Max's sandbox.

Representative fraction = 10/ 25

                                       = 2/ 5

So that;

x = 15 * 2/5

  = 6 ft

y = 12.5 *2/5

  = 5 ft

The perimeter of Max's sandbox = 10 + y + x

                                                      = 10 + 5 + 6

                                                      = 21 ft

(a) The closed form for ∑2 is 2.

(b) The closed form expression for ∑3 is 24.

(c) The closed form for the sum ∑n = 0(― 1)² ― 1 is n(1 - n) / 2.

(d) The value of -3 matches the manual computation of the four terms.

Our closed form solution is correct.

To find the closed form for ∑2, we can use the formula for the sum of the first n terms of an arithmetic series:

∑2 = n(a + l) / 2

In this case, a = 2 (the first term) and l = 2 (the last term) since we are summing a series of 2's.

We also know that there is only one term, so n = 1.

Substituting these values into the formula, we have:

∑2 = 1(2 + 2) / 2

= 4 / 2

= 2

The formula for the sum of the first n terms of an arithmetic series is:

∑n = n(a + l) / 2

In this case, we have a = 3 (the first term), l = 13 (the last term), and n = 3 (the number of terms).

Substituting these values into the formula, we get:

∑3 = 3(3 + 13) / 2

= 3(16) / 2

= 48 / 2

= 24

The formula we developed in class is:

∑n = n(a + a + (n - 1)d) / 2

In this case, we have a = 0 (the first term) and d = -1 (the common difference).

Substituting these values into the formula, we get:

∑n = n(0 + 0 + (n - 1)(-1)) / 2

= n(0 - n + 1) / 2

= n(1 - n) / 2

To test the closed form solution for ∑3 = 0(― 1)² ― 1, we substitute n = 3 into the closed form expression we derived in part (c):

∑3 = 3(1 - 3) / 2

= 3(-2) / 2

= -6 / 2

= -3

Now, let's manually compute the sum of the first four terms of ∑3 = 0(― 1)² ― 1:

0(― 1)² ― 1 + 1(― 1)² ― 1 + 2(― 1)² ― 1 + 3(― 1)² ― 1

= 0 - 1 - 2 - 3

= -6

A polynomial's degree is the greatest power of a variable in a polynomial equation. The degree indicates the highest exponential power in the polynomial (ignoring the coefficients)

Step-by-step explanation:

The degree of a polynomial is the exponent of the leading term. For example, (x + 1) is a first-degree polynomial because x has an exponent of 1. (x^5 + 2y^4 - 3y^3 + y^2 - x + 3) is a fifth-degree polynomial because x has an exponent of 5.

Answer:

24 or 20

Step-by-step explanation:

The required measure of the angle x and y is given as 65° and 25° respectively,

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

here,
According to the angle sum theorem,
The Sum of the remote interior angle is equal to the sum of the remote exterior angle,
So,
y + 90° = 115°
y = 25
Now,
And the sum of the supplementary angle is 180°, so
x + 115° = 180
x = 65°

Thus, the required measure of the angle x and y is given as 65° and 25° respectively,
