The equation Loga(2x) = 1/2 can be simplified to x = (a¹/²)/2.

To solve the given equation: Loga(2x) = 1/2. We will solve this equation step-by-step using the given terms.

Step 1: Convert the logarithmic equation to exponential form.
We know that Loga(b) = c can be rewritten as a^c = b. So, in our case, the equation becomes:

a¹/² = 2x

Step 2: Isolate x.
We want to find the value of x, so we need to isolate it. To do this, divide both sides of the equation by 2:

(a¹/²)/2 = x

And that's the solution! The equation Loga(2x) = 1/2 can be simplified to x = (a¹/²)/2.

The equation of the line passing through the points (0, 2) and (3, 0) is

The equation of the line passing through the points (0, -4) and (5, -1) is

The slope between the points (4,5) and (‐3, 6) is -1/7.

The equation of a line in slope intercept form is written as

y = mx + c

where

m = slope and c is the y- intercept

From the graph points (0, 2) and (3, 0) is used

To find the equation of the line passing through the points (0, 2) and (3, 0), we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

m = (y2 - y1) / (x2 - x1)

m = (0 - 2) / (3 - 0)

m = -2/3

substitute in the point-slope form of the equation of a line. using point (0, 2):

y - y1 = m(x - x1)

y - 2 = (-2/3)(x - 0)

y - 2 = (-2/3)x

y = (-2/3)x + 2

For the second line points (0, -4) and (5, -1) is used

m = (-1 + 4) / (5 - 0)

m = 3/5

Using point (0, 4)

y - y1 = m(x - x1)

y - 4 = (3/5)(x - 0)

y - 4 = 3/5 x

y = 3/5 x + 4

The slope between two points (x1, y1) and (x2, y2) can be calculated using the formula:

slope = (y2 - y1) / (x2 - x1)

slope = (6 - 5) / (-3 - 4)

slope = 1 / (-7)

slope = -1/7

Answer:

Second option 168= 18.X + 12.2X

Step-by-step explanation:

Area of the shape is in two parts,

Are of the larger rectangle is Lenght x width

Lenght is 12cm and width is x +2x

Area = 12 x 3x = 36x cm²

Area of the smaller rectangle = 6 x X = 6xcm²

Total area 36x + 6x = 168cm²

Another method

Find the area of the big rectangle including the cut off area

Lenght x width = 18 x (2x + X)

Area =18 x 3x or 18.3x

Calculate the white area

Length x width = 6 x 2x = 12x

Deduct the white area from the larger area

168= 18.3x - 12x

Third method

Divide the rectangle from top down

First rectangle length x width = 18x X or 18x

Second rectangle length x width = 12 x 2x

168= 18. x + 12 . 2x

The correct equation which can be used to find the value of x is,

⇒ 168 = 18 × x + 12 × 2x

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The figure shown has a total area of 168 cm².

Now, We can find as;

Area of rectangle = Length x width

Hence, We can formulate;

⇒ 18 × x + 12 × 2x = 168

Thus, The correct equation which can be used to find the value of x is,

⇒ 168 = 18 × x + 12 × 2x

In statistics, hypothesis testing is one of the most important techniques used to test claims or statements regarding population parameters. The hypothesis testing process consists of six steps, including state the null and alternative hypotheses.

Null Hypothesis, H0: p ≤ 0.65 Alternative Hypothesis, Ha: p > 0.65 Where p is the proportion of computer chips that do not fail in the first 1000 hours of their use. Now we have to check whether there is sufficient evidence at the 0.01 level to support the company's claim or not. For this, we use the following formula to compute the z-score for the sample proportion.

\($$z=\frac{p-_0}{\sqrt{_0(1−_0)/}}$$\)  where

p0 = 0.65 (assumed under null hypothesis)

p = 0.69 (sample proportion)

n = 900 (sample size) Now, we have,

\($$z=\frac{0.69-0.65}{\sqrt{0.65(1−0.65)/900}}$$ $$\implies z=\frac{0.04}{0.0156}=2.564$$\)

The null and alternative hypotheses for the given scenario are H0: p ≤ 0.65 and Ha: p > 0.65. At the 0.01 level, there is sufficient evidence to support the company's claim that more than 65% of computer chips do not fail in the first 1000 hours of their use.

As per the given equation the height of the cliff is 196.225 feet.

We know that the distance an object falls varies directly as the square of the time it is in motion, meaning that the distance is proportional to the square of the time. If we let d be the distance fallen and t be the time, we can write this relationship as \(d = kt^2\) for some constant of proportionality k.

We also know that when an object falls for 3 seconds, it falls 144.9 feet. We can use this information to find the value of k:

\(144.9 = k(3^2)\)

k = 16.1

Now that we know the value of k, we can use it to find the distance fallen when the time is 3.5 seconds:

\(d = kt^2\\d = 16.1(3.5^2)\\d = 16.1(12.25)\\d = 196.225\)

Answer:

Step-by-step explanation:

You have more than 1/2 the solution just by knowing the slope.

General equation

y = mx + b         where m is the slope and b is the y intercept.

m = 3/4

Solution

y = 3/4 x + b      Now you need the point to solve for b

x = 2

y = 2                  Substitute these values into the line

2 = 3/4 * 2 + b   Simplify the right

2 = 1 1/2 + b

2 = 3/2 + b        Subtract 3/2 from both sides

2 - 3/2 = b         Combine

1/2 = b

So the y intercept is 1/2

Z ⊃ D holds as a result of the indirect proof. Contradiction: our initial assumption ~A ~M is false. Hence, Z ⊃ D holds as a result of the indirect proof.

To complete the proof using indirect proof, we need to assume the opposite of what we want to prove and derive a contradiction.

Here's how we can approach it:
1. (Z & M) ⊃ (S V A)                                   [Given]
2. Z ⊃ ~S                                                  [Given]
Assume Z ⊃ D. We want to show that ~A ~M follows from this assumption.
3. Assume ~A ~M                                     (for indirect proof)
4. From 3, we have ~A                             (by simplification)
5. From 3, we have ~M                            (by simplification)
Now, let's derive a contradiction:
6. From 4, we have A ⊃ S                        (by contrapositive of 1)
7. From 5, we have M ⊃ S                        (by contrapositive of 1)
Since we have assumed Z ⊃ D, we can derive:
8. Z ⊃ ~S ⊃ ~M                                         (by hypothetical syllogism from 2 and 7)
9. From 8, we have Z ⊃ ~M                     (by transitivity)
Now, let's derive another contradiction:
10. From 9, we have Z ⊃ ~M                    (repeated assumption)
11. From 10, we have Z ⊃ S                      (by contrapositive of 7)
Finally, let's use the assumption Z ⊃ D to derive the desired contradiction:
12. From 11, we have ~S                           (by hypothetical syllogism from 10 and 2)
13. From 11 and 12, we have S & ~S        (by conjunction)
Since we have derived a contradiction, our initial assumption ~A ~M is false.

Therefore, Z ⊃ D holds as a result of the indirect proof.

Convenience sampling is the least likely to produce a representative sample of the students.

Using the convenience sampling technique, individuals are chosen based on their accessibility and availability. This kind of sampling is frequently employed in studies when the objective is to swiftly collect data from a sample group rather than to acquire a representative sample of the population. If a person is willing to engage in the study  to the researcher, they are chosen for convenience sampling. The primary advantage of this strategy is that it is very simple and quick to apply; however, the primary downside is that the sample may not be representative of the population.

To find only one fake coin from 8 coins can be done in two weighings.

Divide the coins into three groups, A, B, and C, each consisting of three coins.

A and B are first weighed against one another. If the balancing scale is straight, fake coins belong in group C; otherwise, they belong in A or B, depending on which side of the scale is up.

Finding the lighter fake coin requires a second weighing if the first weighing indicates that the fake coins are in group C. Weigh any two phony coins from the group if A/B. The third coin is phony if the scale is balanced; else, choose the coin that is lighter.

For 3 weighing, make pair of 4 and followed by pair of 2 for the lighter group. At last, compare the last 2 coins to find the lighter coins.

Answer:

45°

Step-by-step explanation:

Since the diagonal cuts the square into two triangles, the angles b, a, and , c all add up to 180°. Because the shape is a square we know that one of the angles is right/90° meaning the two remaining angles are 45°. Angles a, and c had the diagonal drawn through so those two angles are each 45° and b is 90°, and since they are asking for bac we know that they want the middle angle, i.e angle A.

Since ABCD is a square, and AC is the diagonal of the square, therefore, the measure of angle BAC would be: B. 45°.

When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.

Step-by-step explanation:

Answer:

  4) 16√3 in²

  5) 63 cm²

Step-by-step explanation:

The formula to use in these cases is ...

  A = (1/2)ab·sin(θ)

where a, b are the side lengths and θ is the angle between them.

It helps to know the trig functions of the "special" angles used here.

  sin(120°) = sin(60°) = (√3)/2

  cos(60°) = 1/2

  sin(135°) = cos(45°) = (√2)/2

__

4) The external angle at the base is the supplement of 120°, so is 60°. Then the length of the missing segment between the end of the base and the right angle at h is ...

  x = (8 in)cos(60°) = (8 in)(1/2) = 4 in

So, the bottom edge of the triangle is 12 in - 4 in = 8 in.

The area is ...

  A = (1/2)(8 in)(8 in)sin(120°) = (1/2)64(√3)/2 in² = 16√3 in²

__

5) As in the previous problem, the difference between the given horizontal dimension and the base of the triangle is ...

  x = (18 cm)cos(180°-135°) = 18(√2)/2 cm = 9√2 cm

Then the base of the triangle is ...

  16√2 cm -9√2 cm = 7√2 cm

The area is then ...

  A = (1/2)(18 cm)(7√2 cm)(√2)/2 = 63 cm²

a "mean" is an average of a data set.

you can find this by adding all terms together (17 + 12 + 7 + 10 + 9)

and then dividing by the total number of terms (in this case, 5)

so, your equation would be  (17 + 12 + 7 + 10 + 9 = 55) 55 / 5

55 / 5 = 11

so, for this example, 11 would be the mean

....

further explanation:

if the concept of adding terms and dividing to get an average is confusing, try thinking about it with fewer terms,

so the average of 2 and 4 is halfway (1/2) between them. so, 2+4 (6) / 2 = 3

3 is midway between

so, lets say we want to find the average of 3 numbers, like  2, 4, and 6. we want to find the number in between all of these. so like we did for the previous, add 2+4+6 (12) and divide by 3 [# of terms) to get 4.

The length needed to cut off is 12.55 cm

Step-by-step explanation:

The corrected question is:

you need a piece of paper to measure 64.25 cm. If you tape two together that each measure 38.4 cm, how much do you need to cut off?

Solution:

measurement/length of each paper piece = 38.4 cm

measurement/ length required = 64.25 cm

If length of one paper piece is 38.4 cm then if we tape 2 pieces together then the measurement or length is calculated as:

38.4 + 38.4 = 76.8 cm

So to calculate how much we need to cut off:

length required to cutoff = total length of two pieces - length  required

                                         = 76.8 - 64.25

                                         = 12.55 cm

So the length required to cut off is 12.55 cm
