Question.

Rectangle ABCD is shown above. Which of the following expressions
can be used to determine the length of diagonal AC?
O√64 - w²
O√64+w²
O 64-w²
O 64+w²

Answer:

Never true

Step-by-step explanation:

2x - 5 < 2(x - 3) first multiply 2 with the inside the parenthesis

2x - 5 < 2x - 6

now when we simplify the inequality 2x on the both sides will be eliminated and we will be left with:

(-5) < (-6) which cannot be true because (-5) is closer to 0 in number line so it's bigger then (-6) not smaller

Therefore the answer is "Never true"

A local maximum occurs over the interval  (-2,0)  

A local minimum occurs over the interval  (0,2)

How do you find a function's maximum value?

We may calculate the maximum of a continuous and twice differentiable function f(x) by first differentiating it with respect to x and then equating it to 0.

A local maximum occurs over the interval (-2,0)  

A local minimum occurs over the interval  (0,2)

According to transitive property, 0 + x + 13 = x + 13 and also x + 13 is equal to 13 + x. Thus, we can equally say that; 0 + x + 13 is equal to 13 + x

We are told that the Transitive Property states that if a = b and b = c, then a = c.

Now, if a = 3 for example, then by the transitive property, it means that b and c must both also be 5.

Now, we want to apply the the transitive property to show that the expressions 0 + x + 13 and 13 + x are equivalent.

Now, the expression 0 + x + 13 is equal to x + 13.

Now, according to transitive property, 0 + x + 13 = x + 13 and also x + 13 is equal to 13 + x. Thus, we can equally say that;

0 + x + 13 is equal to 13 + x

We have given a sample size of n=40

Sample mean ¯x=$6.88 per 100 pounds

Population standard deviation= 1.96 per 100 pounds

First, we need to find the value of z α /2 =z (1−0.90/2)

Z (α/2) =z0.05

Z (α/2) =1.645

(a)The required 90% confidence interval is;

¯x ± margin of error

¯x ± z (α/2) * σ/sqrt 40

6.88 ± 1.645 * 1.96/sqrt 40

6.88±0.5097

(6.38,7.38)

Therefore, the lower limit is $6.38 per 100 pounds.

The upper limit is $7.38 per 100 pounds.

The margin of error is 0.50 per 100 pounds.

(b) to have the maximum of E, we use the formula;

n= (z (α/2)×σ/E) ^2

n= (1.645× (1.96/0.41)) ^2

n=61.84≈62

Therefore, the required farming region will be 62.

Using the fact that the two angles are complementary, the we will find that the measures are:

∠1 = = 14°

∠2  = 76°

By looking at the diagram, we can see that the sum of the measures of angles 1 and 2 must be equal to 90° (this means that the two angles are complementary).

We also can see that:

∠1 = x - 5

∠2 = 4x

Then we can solve the linear relation:

(x - 5) + 4x = 90

x - 5 + 4x = 90

5x - 5 = 90

5x = 90 + 5 = 95

x = 95/5 = 19

Then the measures of the two angles are:

∠1 = (x - 5)° = (19 - 5)° = 14°

∠2 = 4x = 4*19° = 76°

A statement that explains the equation 13x - 13y = -26 shares a solution with given system of equations because 13x - 13y equals 55.

The equation system is presented below;

10x - 3y = 29       .........equation 1

-3x + 10y = 55     ..........equation 2

As a result of subtracting equation (2) from equation (1), we get;

By subtracting equivalent expressions, (10x - 3y) - (-3x + 10y) = 29 - 55.

13x - 13y = 29 - 55 = -26

Provided that the operation on equations (1) and (2) is the same, the given equation is 13x - 13y = -26.

We can see from the subtraction of equivalent representations that the solution for the

The solution for given equation, 13x - 13y = -26, is like the solution for given equation.

The reason why 13x - 13y = -26 has the same solution as the system of equations is that -3x + 10y is equal to 55, so we can subtract -3x + 10y from the left side of 10x - 3y = 29 and subtract 55 from the right side.

Thus, subtracting equivalent representations from each side of the an equation has no effect on the equation's solution.

The sum of the three values is 10.25 meters.

Here, we are given three measurements- 7.5m, 2.25m and 50cm

Since, we need to find the answer in meters, let us convert all the units to meters so that we can add them.

7.5 and 2.25 are already in meters so we do not need to covert them.

We only need to convert 50 centimeters.

As per mathematical conversions,

1 meter = 100 centimeters

This means that 50 centimeters will be,

100/2 centimeters = 1/2 meters

⇒ 50 centimeters = 0.5 meters

Now, we add all the given numbers,

= 7.5 + 2.25 + 0.5

= 9.75 + 0.5

= 10.25

Thus, the sum is 10.25 meters.

The owner's profit for a ten-day period is equal to $ 6100.

We are given that:

Selling price of 1 pizza slice =  $ 2.50

Number of pizza slice sold per day = 200

Selling price for pizza slices in a day = 200 × $ 2.50

SP ( pizza ) = $ 500

Selling price of 1 sandwich = $ 2

Number of sandwich sold per day = 85

Selling price for pizza slices in a day = 85 × $ 2

SP ( sandwich ) = $ 170

Selling price in 1 day = $ 500 + $ 170 = $ 670

Now, Cost price in 1 day = $ 60

Profit in  1 day = $ 670 - $ 60 = $ 610

Profit in 10 days = 10 × $ 610 = $ 6100

Small, random genetic changes that occur over generations is known as genetic drift.

Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population. The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.

Some people might merely by coincidence leave behind a few more offspring (and genes, of course!) than others in each generation. The next generation's DNA and other genetic components will come from the "fortunate" people, not necessarily the healthier or "better" people.

The x is the adjacent side to the reference angle. The 7 is the hypotenuse. The hypotenuse is always opposite the 90 degree angle.

Let's use the trig ratio cosine.

Answer:

350p2+19500p-199000

(The first term is actually -350p² but I guess you have to write it as -350p2)

Step-by-step explanation:

Looks like that first term in the revenue equation is -350p²

We have
E = -1500p + 199000
R = -350p² + 18000p

Profit = Revenue - Expenses = R - P

Profit = -350p² + 18000p - (-1500p + 199000)

= 350p² + 18000p + 1500p - 199000

= 350p² + 19500p - 199000

The slope of the line shown is 1/5, and being parallel means having the same slope. So it’s either a or b.

Next, you plug in (-2, 2) into y=1/5x+b to find b.

Solving you get: 2=1/5 * -2 +b

2=-2/5+b

B=2 2/5

12/5 = 2 2/5

So the answer is b.
