Please hurry I need the answer like now, but I am confused. Your supposed to solve for x.​

Answer:

D

Step-by-step explanation:

First, you must solve this equation

6x+14=3(2x+5)

distribute 3 on the right side

6x+14=6x+15

subtract 6x on both sides

14=15

Since there are no values of x that will make this true, the answer is equal to no solutions, so it's D

the integral of the line, where c is the specified curve. The line integral is (x 9y) dx x2 dy, where C is the provided curve. The line segments from (0, 0) to (9, 1) and from (9, 1) to (10, 0), respectively, make up the integral c (x+2y)dx+x2dy, C. is 95/3

\(\int\limits^a_c {(x+9y,x^{2} )} \, dr_{2} = \int\limits^1_0{9+t+9-9t, (9+t )^2} .(1, -1)\, dt\)

it is possible to parameterize the first line segment by

\(r_{1} (t) = (0,0)(1-t) + (9,1)t = (9t,t)\) with 0 ≤ t ≤ 1 indicate this first section with \(C_{1}\) then

\(\int\limits^a_c {(x}+9y,x^2 ) \, dr_{1} = \int\limits^1_0 {(9t+9t,81t^2) . (9,1)} \, dt\\ \\= \int\limits^1_0 {(162t + 81t^2) } \, dt\\\\= 108\)

secondly the line segment \(C_{2}\) can be characterised as

\(r_{2} (t) = (9,1)(1-t) + (10,0)t = (9+t,1-t)\) again using interval  0 ≤ t ≤ 1  then

\(\int\limits^a_c {(x+9y,x^{2} )} \, dr_{2} = \int\limits^1_0{9+t+9-9t, (9+t )^2} .(1, -1)\, dt\)

= -229/3

finally ,

= 108-229/3

= 95/3

Answer:

Step-by-step explanation:

The solution to the equation 91 = 29^x is approximately x ≈ 1.08.

To solve for x in equation 91 = 29^x, we need to isolate the variable x. Here's the step-by-step process:

Add 150 to both sides of the equation to get rid of the constant term:

91 + 150 = 29^x + 150

Simplify the equation:

241 = 29^x + 150

Subtract 150 from both sides:

241 - 150 = 29^x

Simplify further:

91 = 29^x

Now, we can solve for x by taking the logarithm of both sides of the equation with base 29. Using the logarithm property log_b(a^c) = c * log_b(a), we have:

log_29(91) = x

Using a calculator or logarithm table, we can find that log_29(91) ≈ 1.08.

Therefore, the solution to the equation 91 = 29^x is approximately x ≈ 1.08.

Percentage of a number exists the value of the number out of 100. Percentage of money spend on roof tiles is 39.52%.

Percentage of a number exists the value of the number out of 100. When expressing a proportionate share of a total, percentages are frequently utilized.

Given: Total budget £3900.

Money spends on bricks is 34%  

Money spends on cement is 17%

Money spends on timber £370

Percentage of money spend on timber = 370 / 3900 × 100 = 9.4871 %

Percentage of money spend on roof tiles = 100 - (34% + 17% + 9.4871 %)

Step-by-step explanation:

Using Pythagoras theorem:

\( = \sqrt{{20}^{2} - {12}^{2} } \)

\( = \sqrt{400 - 144}\)

\( = \sqrt{256} \)

\( = 16\)

We have derived the following equations:

(10) Y = 7,000 - 200r - 1,000ε
(11) 10 = r + 5ε
(12) NX = 500 - 500r - 2,500ε
(13) CF = -50,000 + 50,000r + 250,000ε

To solve the given equations for the equilibrium values of C, NX, CF, r, and ε, let's go step by step.

First, we'll substitute equations (2), (3), (4), (5), (6), (7), (8), and (9) into equation (2) to eliminate the variables C, I, G, NX, CF, and T.

Equation (2) becomes:
Y = (1/2)(Y - T) + (2,000 - 100r) + 1,500 + (500 - 500ε)

Next, let's simplify the equation:

Y = (1/2)(Y - 1,000) + 2,000 - 100r + 1,500 + 500 - 500ε

Distribute (1/2) to the terms inside the parentheses:

Y = (1/2)Y - 500 + 2,000 - 100r + 1,500 + 500 - 500ε

Combine like terms:

Y = (1/2)Y + 3,500 - 100r - 500ε

Now, let's isolate Y by subtracting (1/2)Y from both sides:

(1/2)Y = 3,500 - 100r - 500ε

Multiply both sides by 2 to get rid of the fraction:

Y = 7,000 - 200r - 1,000ε

We now have one equation (10) in terms of Y, r, and ε.

Next, let's substitute equation (1) into equation (10) to solve for Y:

5,000 = 7,000 - 200r - 1,000ε

Subtract 7,000 from both sides:

-2,000 = -200r - 1,000ε

Divide both sides by -200:

10 = r + 5ε

This gives us equation (11) in terms of r and ε.

Now, let's substitute equation (11) into equation (5) to solve for NX:

NX = 500 - 500ε

Substitute r + 5ε for ε:

NX = 500 - 500(r + 5ε)

Simplify:

NX = 500 - 500r - 2,500ε

This gives us equation (12) in terms of NX, r, and ε.

Finally, let's substitute equation (12) into equation (6) to solve for CF:

CF = -100r

Substitute 500 - 500r - 2,500ε for NX:

CF = -100(500 - 500r - 2,500ε)

Simplify:

CF = -50,000 + 50,000r + 250,000ε

This gives us equation (13) in terms of CF, r, and ε.

To summarize, we have derived the following equations:

(10) Y = 7,000 - 200r - 1,000ε
(11) 10 = r + 5ε
(12) NX = 500 - 500r - 2,500ε
(13) CF = -50,000 + 50,000r + 250,000ε

These equations represent the equilibrium values of Y, r, ε, NX, and CF in the given open economy.

N is congruent to k+1 modulo 3, and since k+1 is not divisible by 3, N is not divisible by 3. Hence, we have shown that if the sum of the digits of a natural number is divisible by 3, then the number itself is not divisible by 3. This can be answered by the concept of Polynomial.

Suppose we have a natural number N = d_k * 10^k + d_{k-1} * 10^{k-1} + … + d_1 * 10 + d_0, where each d_i is a digit between 0 and 9 inclusive, and k is the number of digits in N minus 1. We can recognize N as the evaluation of the polynomial f(x) = d_k * x^k + d_{k-1} * x^{k-1} + ... + d_1 * x + d_0, evaluated at x = 10. Note that f(x) has integer coefficients and degree k, and thus satisfies the conditions of the theorem.

For example, let's consider a natural number N represented as a polynomial f(x) = a_nx^n + a_(n-1)x^(n-1) + … + a_0. To determine if N is divisible by 3, we can check if f(a) ≡ f(b) (mod 3) for integer values of a and b. Similarly, to determine if N is divisible by 9, we can check if f(a) ≡ f(b) (mod 9) for integer values of a and b. Using this theorem, we can deduce divisibility criteria for natural numbers by 3 or 9.

Now, suppose the sum of the digits of N is divisible by 3. Then we can write N = 3m for some integer m. Note that 10 is congruent to 1 modulo 3, so by the theorem, we have f(10) is congruent to f(1) modulo 3. But f(10) = N and f(1) = k+1, since the sum of the coefficients of f(x) is equal to k+1.

Therefore, N is congruent to k+1 modulo 3, and since k+1 is not divisible by 3, N is not divisible by 3. Hence, we have shown that if the sum of the digits of a natural number is divisible by 3, then the number itself is not divisible by 3.

There is a way to remember the ways to solve for right triangles, SOH CAH TOA which stands for each of the ways to solve for angles or sides:

Sine: Opposite over Hypotenuse

Cosine: Adjacent over Hypotenuse

Tangent: Opposite over Adjacent

In this case, with the information we have, we would use tangent since we have both the opposite side, b, and the adjacent side, a.

It would be the inverse of tangent (tan⁻¹) since you are solving for the angle and not a side.

You would use a calculator to solve this, by dividing b by a.

tan⁻¹(b/a)

tan⁻¹(46.7/31.3) = 56.1686012868

Round to the nearest tenth = 56.2

1. The power set of A (P(A)): The power set of a set A is the set of all possible subsets of A, including the empty set and the set itself.

In this case, A = {1, 6, 8, 9}. To find the power set P(A), we list all possible subsets of A:

P(A) = {{}, {1}, {6}, {8}, {9}, {1, 6}, {1, 8}, {1, 9}, {6, 8}, {6, 9}, {8, 9}, {1, 6, 8}, {1, 6, 9}, {1, 8, 9}, {6, 8, 9}, {1, 6, 8, 9}}

2. {A} × {B} and {B} × {A}:

{A} × {B} represents the Cartesian product of sets A and B, which is the set of all ordered pairs where the first element comes from set A and the second element comes from set B.

In this case, A = {1, 6, 8, 9} and B = {∅}. Thus, {A} × {B} would be:

{A} × {B} = {(1, ∅), (6, ∅), (8, ∅), (9, ∅)}

Similarly, {B} × {A} would be:

{B} × {A} = {(∅, 1), (∅, 6), (∅, 8), (∅, 9)}
