Answer:
Step-by-step explanation:
use equation [tex]\frac{y2-y1}{x2-x1}[/tex] to calculate the slope, in this case the slope would be [tex]\frac{11-11}{3-(-2)}=\frac{0}{6} =0[/tex]
The slope would be 0 for the line,
another way we can tell the slope is 0 is that we can see the two sets of coordinates are on the y=11, they just have different x coordinates.
But the equation above shows the complete work and supported the answer.
Answer:
Slope (m) = 0
Step-by-step explanation:
Given coordinates,
→ T(-2, 11)
→ U(3, 11)
Formula we use,
→ Slope = (y2 - y1)/(x2 - x1)
Now required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (11 - 11)/(3 -(-2))
→ m = (0)/(3 + 2)
→ m = 0/6
→ [ m = 0 ]
Therefore, the slope is 0.
Let f(x) = 5(3)x
The graph of f(x) is stretched vertically by a factor of 2 to form the graph of g(x).
Choose the equation of g(x).
Responses
g(x) = 10(3)xg(x) = 10(3)x
g(x) = 7(3)xg(x) = 7(3)x
g(x) = 2(3)xg(x) = 2(3)x
g(x) = 5(6)x
The required equation is g(x) = 10(3)x which is the correct answer would be an option (A).
The graph of g(x) is obtained by stretching the graph of f(x) vertically by a factor of 2.
Since the vertical stretch of a graph multiplies the y-coordinates of each point on the graph by a constant factor, the equation of g(x) must be obtained by multiplying the y-coordinate of each point on the graph of f(x) by 2.
In the given equation f(x) = 5(3)x, the y-coordinate of each point on the graph of f(x) is 5(3)x.
Thus, to stretch the graph of f(x) vertically by a factor of 2, we need to multiply this y-coordinate by 2 to get the y-coordinate of the corresponding point on the graph of g(x). This gives us the following equation for g(x):
⇒ g(x) = 2 × 5(3)x = 10(3)x
Therefore, the required equation is g(x) = 10(3)x.

6/7 × 1/2 = ?
Answer:
To solve this problem, we need to first perform the multiplication. In mathematics, multiplication is performed before division, so we should calculate the product of 6/7 and 1/2 before dividing it by any other number. To find the product, we simply multiply the numerators together to get 6 and the denominators together to get 14. So the product of 6/7 and 1/2 is 6/14.
Step-by-step explanation:
the product of 0.8 and a number is 12represent the statement as an equation determine the solution set using the replacement set 0 8 1 7 15
Answer:
The product of 0.8 and a number is 12, so the equation representing this statement is: 0.8 * x = 12.
To solve this equation, we need to find the value of x that makes the equation true. We can do this by using the replacement set {0, 8, 1, 7, 15}.
If we substitute 0 for x in the equation, we get: 0.8 * 0 = 12. This equation is not true, so 0 is not a solution.
If we substitute 8 for x in the equation, we get: 0.8 * 8 = 12. This equation is not true, so 8 is not a solution.
If we substitute 1 for x in the equation, we get: 0.8 * 1 = 12. This equation is not true, so 1 is not a solution.
If we substitute 7 for x in the equation, we get: 0.8 * 7 = 12. This equation is not true, so 7 is not a solution.
Finally, if we substitute 15 for x in the equation, we get: 0.8 * 15 = 12. This equation is true, so 15 is a solution.
Therefore, the solution set for this equation is {15}.

Read the following statement: All real numbers have a reciprocal. Which of the following choices is a counterexample to the statement?
0
1
-7
1/4
Reciprocal of zero is undefined. So all the real numbers do not have the
reciprocal.
What is a reciprocal?The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.
We have the statement,
''All real numbers have a reciprocal''.
To find a counterexample:
The reciprocal of the number zero will always have the value "undefined".
Since there is no number that, when multiplied by zero, produces the result 1.
If n is a real number, then 1/n will be n's reciprocal.
n = 1,
So, the reciprocal of 1 is 1/1 = 1.
n = -7,
So, the reciprocal of -7 is 1/-7= -1/7.
And n = 1/4
So, the reciprocal of 1/4 is 1/(1/4)= 4/1 = 4.
Hence, reciprocal of zero gives us to disprove the statement.
Therefore, All real numbers have the reciprocal, except zero.

√6/8
√6/4
√3/4
√24/8
Answer:
1/8
Step-by-step explanation:
To simplify the expression √3/√8, we can first simplify the square root terms by finding the prime factorization of each number under the square root. The prime factorization of 3 is 3, and the prime factorization of 8 is 2 * 2 * 2.
We can then rewrite the square root terms as follows:
√3/√8 = √(3) / √(2 * 2 * 2)
Next, we can use the property of square roots that says that the square root of a number is equal to the square root of each of its prime factors. This means that we can rewrite the square root term as follows:
√(3) / √(2 * 2 * 2) = √(3) / √(2) / √(2) / √(2)
Since the square root of a number is the same as the number itself, we can simplify the expression further by removing the square root symbols from the prime numbers 2:
√(3) / √(2) / √(2) / √(2) = √(3) / 2 / 2 / 2
Finally, we can use the rules of division to simplify the expression even further:
√(3) / 2 / 2 / 2 = √(3) / (2 * 2 * 2)
Since any number divided by itself is equal to 1, we can simplify the expression one last time to get our final answer:
√(3) / (2 * 2 * 2) = 1/2 * 1/2 * 1/2 = 1/8
Therefore, the simplified form of the expression √3/√8 is 1/8.

Answer: $879,489
Step-by-step explanation:
When it comes to a business net worth is simple:
assets - liabilities = net worth.
Assets are an expenditure that has utility through multiple future accounting periods. For example, a company pays its electrical bill. This expenditure covers something (electricity) that only had utility during the billing period; therefore, it is recorded as an expense.
Conversely, the company buys a machine, that it expects to use for the next five years. Since this expenditure has utility through multiple future periods, it is recorded as an asset.
Cash, savings, inventory, investments, equipment, and receivables are also assets. Basically, anything that is owned and could be liquidated for cash.

Which investment is less risky based on coefficient of variation? Which is a better measure given that the expected returns of the two investments are not the same?
a) Investment B is less risky based solely on the standard deviation.
b) Based on the coefficient of variation, Investment B is less risky.
c) The better measure of expected returns of the two investments is the coefficient of variation.
What is the coefficient of variation?The coefficient of variation shows how spread out or variable the standard deviation is to population mean.
It is a ratio of the standard deviation compared to the population mean.
A higher coefficient of variation shows a greater dispersion or risk.
The formula for the coefficient of variation is given as follows:
Coefficient of Variation (CV) = (Standard Deviation/Mean) × 100.
Investments A B
Expected annual returns 15% 12%

Find the value of x and snow work please .
Applying angle relationships, the value of x in each figure is determined as:
E. x = 8
F. x = 26
I. x = 9
J. x = 4
How to Apply Angle Relationship to Find the Value of x?Using angle relationship based on the angles involved, create an equation in each case, to enable you find the value of x.
E. 27 + 8x - 1 = 90 [the angle relationship is that they are complimentary angles].
Solve for the value of x:
26 + 8x = 90
8x = 90 - 26
8x = 64
x = 8
F. 7x - 44 = 75 + 63 [vertical angles are congruent]
7x = 182
7x/7 = 182/7
x = 26
I. 180 - (5x - 3 + 13x + 4) = 17 [vertical angles are congruent]
180 - (18x + 1) = 17
180 - 18x - 1 = 17
179 - 18x = 17
-18x = 17 - 179
-18x = -162
x = 9
J. 3y + 10 = 5y - 24 [vertical angles are congruent]
Solve for y
3y - 5y = -10 - 24
-2y = -34
y = 17
Find the value of x:
3y + 10 + 9x + 1 + 82 = 180 [angles on a straight line equals 180 degrees]
3y + 9x + 93 = 180
Plug in the value of y
3(17) + 9x + 93 = 180
51 + 9x + 93 = 180
9x + 144 = 180
9x = 180 - 144
