Answer:

In explanation below.

Step-by-step explanation:

Presumably, the proof you have in mind is to use a=b=2–√a=b=2 if 2–√2√22 is rational, and otherwise use a=2–√2√a=22 and b=2–√b=2. The non-constructivity here is that, unless you know some deeper number theory than just irrationality of 2–√2, you won't know which of the two cases in the proof actually occurs, so you won't be able to give aa explicitly, say by writing a decimal approximation.

Answer:

10 - x

Step-by-step explanation:

Since f(x) = 10 - 3, we can replace the "f(x)" in the equation with "10 - 3". Likewise, we can replace the "g(x)" in the equation with "-x + 3" because g(x) = -x + 3:

10 - 3 - x + 3

The new height of painting by Jacob will be 2.5 inches.

The ratio and proportion will be used to relate the original and reduced dimensions of painting. The original width and height = 42.88/33.5. Let us assume the new height be x. So, new width and height = 3.2/x. Equating these two fractions -

42.88/33.5 = 3.2/x

Rewriting the equation according to x

x = (3.2 × 33.5) ÷ 42.88

Performing multiplication in numerator

x = 107.2 ÷ 42.88

Performing division on Right Hand Side of the equation

x = 2.5

Thus, the new height will be 2.5 inches.

The Confidence interval is (0.85,1.05) which contain the sample proportion for 95%of samples size.

Confidence interval is an interval with a confidence level. Confidence interval is always constructed on basis of sample , p = sample statistic - margin of error to sample statistic + margin of error

Confidence interval for a proportion are calculated using the following formula:

p= ( p' - Z√p'(1-q')/n , p'+ Z √p'(1-p')/n ) ---(1)

where, p' ---> sample proportion for sucess

1-p' -----> sample proportion for failure

Z --> Z-value (statistic value)

n---> sample size

we have given that,

sample size ( n)=850 , sample proportion (p') = 0.95 and population proportion= 0.75

a) mean of sample of proportion is same as poplution proportion i.e 0.75 ..

1 -p' = q' = 0.05

Using the formula for margin of error ,

M .E = Z √ p'q'/n ---(2)

as the Z-value for given proportion is 13.46

putting all values in equation( 2) we get,

M.E = 13.45 √0.95×0.05/850 = 0.1005

Now, we shall calculate the confidence interval for given data

confidence interval (p)

= ( 0.95 - 0.100 , 0.95 + 0.100)

p= ( 0.85 , 1.05)

Hence,confidence interval(CI) is (0.85, 1.05).

The value of the variables in the figure is x = 60 degrees and y = 10 degrees.

From the figure:

x + 120 = 180 (since consecutive interior angles equal to 180)

x = 180 - 120

x = 60 degrees.

3y + 40 + 3x - 70 = 180(since supplementary angles = 180)

3y + 3x - 30 = 180

3(y + x) = 180 + 30

y + x = 210/3

y + x = 70

substitute x value

y + 60 = 70

y = 70 - 60

y = 10 degrees.

Therefore the value of the variables in the figure is x = 60 degrees and y = 10 degrees.

The elevation of the hole after placing the bush in the hole is 17/8 feet

Given: Davis digs a hole at a rate of 3/4 feet every 10 minutes

After digging for 40 minutes, Davis places a bush in the hole that fills exactly 7/8 feet of the hole

This involves subtraction and multiplication of fractions

Since the rate of digging = 3/4 feet every 10 minutes

Thus, after digging for 40 minutes, the depth will be:

3/4 × 4 = 3 feet

If Davis places a bush in the hole that fills exactly 7/8 feet of the hole, the remaining depth or elevation will be:

3 feet - 7/8 feet = 17/8 feet

Therefore,  after placing the bush in the hole, the elevation of the hole is 17/8 feet

the slope of the given point is m=9

The value of all the missing angles is in the measure of m∠1 = 88°, m∠2 = 42°, and m∠3 = 113°.

We know that,

Sum of all angles of triangle = 180°.

Therefore, m∠3 + 42° + 25° = 180°.

m∠3 = 180° - 67°

m∠3 = 113°

Vertical angles: Vertical angles are the angles that are opposite to each other when two lines cross.

We know that,

Vertical or opposite angles have equal measures.

So, 42° and m∠2 are vertical or opposite angles.

Therefore, the value of m∠2 = 42°.

Similarly, for m∠3, We know that,

Sum of all angles of triangle = 180°.

∴ ∠1 + ∠2 + 50° = 180°.

The given sequence is geometric sequence not arithmetic.

An arithmetic sequence is a sequence in which the difference between every two consecutive terms is constant

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. It is found by taking any term in the sequence and dividing it by its preceding term.

Difference between arithmetic and geometric sequence:

An arithmetic sequence has a constant difference between each consecutive pair of terms

while

A geometric sequence has a constant ratio between each pair of consecutive terms.

Here, we have a sequence 5,10,20.

So a₁ = 5, a₂ = 10, a₃ = 20

Difference = a₃- a₂ = 20 - 0 = 10

                    a₂ - a₁ = 10 - 5 = 5

Since the difference is not constant, therefore the given sequence is not arithmetic.

Now ratio a₃/a₂ = 20/10 =2 and a₂/a₁ = 10/5 =2 which is same which shows the sequence is geometric.

Therefore, the sequence is geometric sequence.

x ≤ 3

D: 5 is not a solution.

Answer:

D) 5

Step-by-step explanation:

To solve this problem, we must first isolate the variable and simplify the inequality. Isolating the variable means having the variable on one side of an equation or inequality without any other terms?

How do you isolate a variable?

Here's an example.

x+3=18

What can we do to have x on its own side of the equation? Currently, 3 is also with it. If we subtract 3 on both sides, we are leaving the equation with the same answer.

x + 3 - 3= 18 - 3

Combine like terms.

x = 21

That's how you solve for an equation.

Next, an example with division.

3x = 21

How do we solve for x this? Well, we know that 3x = 3 times x. So, to solve for x, we remove the 3. Since its 3 times x, lets divide by 3 on both sides.

[tex]\frac{3x}{3} =\frac{21} {3}[/tex]

Simplify:

3x/3 means 3 times x divided by 3. 3/3 = 1

1x = 21/3

21/3 = 7

x = 7

Now lets get to the problem.

[tex]-4x + 9 \geq -3[/tex]

The first step is to subtract by 9 on both sides so we can work our way to isolating the variable and solving the problem.

[tex]-4x + 9 -9\geq -3 - 9[/tex]

Simplify.

[tex]-4x \geq -12[/tex][tex]-4x \geq -12[/tex]

Now heres the tricky part. To solve for an equation, we must remove -4 from x, or -4 times x. In an equality, which states that:

A [tex]\geq , \leq , > , or < B[/tex]

If you divide or multiply both sides by a negative number, which means the number is less than 0, you must flip the sign!

When you multiply/divide by a negative number or both sides in an equality:

[tex]\leq[/tex] [tex]\geq[/tex]

[tex]\geq[/tex] [tex]\leq[/tex]

> <

< >

So, we currently have:

[tex]-4x \geq -12[/tex]

Divide by -4 on both sides.

[tex]\frac{-4x}{-4} \geq \frac{-12}{-4}[/tex]

Simplify. (Use the rule which states that a negative number multiplied or divided by another negative number equates to a positive number).

[tex]x \geq 3[/tex]

Flip the sign (This is a crucial step!)

[tex]x \leq 3[/tex]

Now, [tex]x \leq 3[/tex] means any number equal to or lower than 3 satisfies the conditions of the inequality.

Is -3 lower than or equal to 3?

Yes; Lower

Is -1 lower than or equal to 3?

Yes;

Is 3 lower than or equal to 3?

Yes; Equal

Is 5 lower than or equal to 3?

D, 5 is your answer as it does not satisfy the inequality.

The Average speed is 17.4 mph.

The average speed is calculated by dividing the total distance travelled by the total amount of motion time.

The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.

Average speed = Distance travelled/ Time taken

Given:

Distance = 5 4/5 = 29/5 miles

Time= 1/3 hours

So, Average speed = Distance travelled/ Time taken

Average speed= 29/5 x 3/1

                         = 87/5
