To bisect a segment, Jessica should place the compass on one endpoint, open it to a width larger than half of the segment, draw two intersecting arcs with the compass, and draw a straight line through the intersection points to bisect the segment.

To bisect a segment, Jessica should first place the compass on one endpoint of the segment and open it to a width larger than half of the segment. She should then draw an arc that intersects the segment at two points. Next, she should place the compass on the other endpoint of the segment and draw a similar arc that intersects the first arc she drew.

Finally, she should draw a straight line through the two points where the arcs intersect to bisect the segment into two equal parts. This method is based on the concept of congruent triangles, as the two arcs create two congruent triangles with the segment as their base.

Temperature change for water due to sheer drop is approximately 0.7 °C when Multnomah Falls in the Columbia River has a sheer drop of 543 ft.

Given that,

Multnomah Falls in the Columbia River Gorge has a sheer drop of 543 feet.

We have to find estimate the water temperature change in °F caused by this drop using the steady flow energy equation.

We know that,

Sheer drop is z₁ - z₂ = 543 feet

We required to calculate temperature change that is ∆T caused by this drop using steady flow energy equation says SFEE.

Assuming

Adiabatic flow i.e. Q =0

No work done, i.e. W=0

Neglecting kinetic energies.

Steady flow energy equation is a mathematical expression that states that for a steady flow the net energy at the inlet of control volume is equal to the net energy at the exit of of the control volume.

SFEE is given as,

h₁ + \(\frac{(v_1)^2}{2}\) + gz₁ + Q = h₂ + \(\frac{(v_2)^2}{2}\) + gz₂ + Q -------> equation(1)

Where, h₁ and h₂ enthalpies at inlet and exit of control volume,

v₁ and v₂ are velocities at inlet and exit of control volume (kinetic energies),

z₁ and z₂ are elevation at inlet and exit of control volume (potential energies),  

Q is energy flow into the control volume and

W is work done by control volume.

Neglecting change in kinetic energies ; Q=0; W=0

Then equation (1) will be,

h₁ - h₂ = g(z₂ - z₁)

Cp(ΔT) =  g(z₂ - z₁)

ΔT = \(\frac{g(z_2-z_1)}{Cp}\)

Here,

Value of g is 32.2 feet per second square and value of Cp for water is 25100 feet

Substituting all values we get,

ΔT = \(\frac{32.2(543)}{25000}\)

ΔT = 0.69°C

ΔT = 0.7°C (approximately)

Therefore, Temperature change for water due to sheer drop is approximately 0.7 °C.

Answer:

C

\(y=(5x+2)(x+3)\)

\(\implies x=-\dfrac25,\ \ x=-3\)

Step-by-step explanation:

Factor  \(y=5x^2+17x+6\)

Multiply the coefficient of \(x^2\) and the constant:  

⇒ 5 x 6 = 30

Find factors of 30 that add together to make the coefficient of \(x\):  

⇒ 2 and 15

Rewrite 17x as 15x + 2x:

\(\implies y=5x^2+15x+2x+6\)

Group:

\(\implies y=(5x^2+15x)+(2x+6)\)

Factor brackets:

\(\implies y=5x(x+3)+2(x+3)\)

Factor out common term \((x + 3)\):

\(\implies y=(5x+2)(x+3)\)

To find the zeroes, set y to zero and solve for x:

\(\implies (5x+2)(x+3)=0\)

\(\implies 5x+2=0 \ \ \textsf{and} \ \ x+3=0\)

\(\implies x=-\dfrac25,\ \ x=-3\)

ac is 5(6)=30

The Excel function used when calculating the t critical value is the T.INV function.

The TINV function returns the inverse of the Student's t-distribution, which is a probability distribution that is commonly used in hypothesis testing when the sample size is small and the population standard deviation is unknown. The TINV function requires two arguments: the probability value (alpha) and the degrees of freedom.

The degrees of freedom depend on the sample size and the number of parameters estimated in the model. The TINV function returns the value of the t statistic that corresponds to a given probability and degrees of freedom. This t critical value is compared to the calculated t statistic to determine if the null hypothesis should be rejected or not.

\(\huge\boxed{\sf x < 4}\)

Step-by-step explanation:

-4x + 7 > x - 13

Subtract x to both sides

-4x - x + 7 > -13

-5x + 7 > -13

Subtract 7 to both sides

-5x > -13 - 7

-5x > -20

Divide -5 to both sides

x < -20/-5

\(\rule[225]{225}{2}\)

Answer:

\(x < \bf 4\)

Step-by-step explanation:

\(-4x + 7 > x -13\)

We have to make \(x\) the subject of the equation:

• Subtract \(x\) from both sides:

\(-4x - x + 7 > -13\)

⇒ \(-5x + 7 > -13\)

• Now subtract 7 from both sides:

\(-5x > -13 - 7\)

⇒ \(-5x > -20\)

• Next divide both sides by -5, and remember that dividing an inequality by a negative number reverses the inequality symbol:

\(x < \frac{-20}{-5}\)

⇒ \(x < \frac{20}{5}\)

⇒ \(x < \bf 4\)

Step-by-step explanation:

x+y=7 is parallel to 3x+3y=3 and -6x-6y=3

Using the Pythagorean theorem, we can calculate the distance Derrick covered as the hypotenuse of a right triangle formed by his movements:

Distance = √((4 ft)² + (6 ft)²) = √(16 + 36) =√(52) ≈ 7.21 ft

Therefore distance covered by Derrick is 7.21 ft.

To find Derrick's displacement, we need to calculate the straight-line distance from his starting point to his ending point. We can use the fact that his southward movement and his eastward movement form the adjacent and opposite sides of a right triangle, respectively. Thus, his displacement is the hypotenuse of this right triangle:

Displacement = √((4 ft)² + (6 ft)²) = √(16 + 36) = √(52) ≈ 7.21 ft

Note that the distance and displacement are the same in this case because Derrick ended up at the same distance from his starting point, but in a different direction. If he had crawled more to the east or west, his distance traveled would have increased, but his displacement would still be the same as it only depends on the straight-line distance between his starting and ending points.

Therefore, Linda bought 21 yards of ribbon. Hence, Linda bought 94 yards of ribbon.

The number of yards of ribbon Linda bought, we need to calculate the difference between the initial balance on the card and the remaining balance after the purchase.

The initial balance on the card was $20. To find the amount spent on ribbon, we subtract the remaining balance ($17.06) from the initial balance. $20 - $17.06 = $2.94

Now, we need to determine how many yards of ribbon Linda could purchase with $2.94, given that the price of the ribbon is 14 cents per yard.

To find the number of yards, we divide the total amount spent ($2.94) by the price per yard (14 cents): $2.94 ÷ $0.14 = 21

Therefore, Linda bought 21 yards of ribbon.

Hence, Linda bought 94 yards of ribbon.

A) Depreciation charge 16,000; revaluation surplus £20,000

According to IAS 16 Property, Plant and Equipment, the depreciation charge for an asset should be based on its carrying amount, useful life, and residual value.

In this case, the buildings were purchased for £400,000 (£480,000 - £80,000) and had a useful life of 25 years. Since there is no residual value, the depreciable amount is equal to the initial cost of the buildings (£400,000).

To calculate the annual depreciation charge, we divide the depreciable amount by the useful life:

£400,000 / 25 = £16,000

Therefore, the depreciation charge for the year ended 30 September 2021 is £16,000.

Now, let's calculate the balance on the revaluation surplus as at that date.

The revaluation surplus is the difference between the fair value of the property and its carrying amount. On 1 October 2020, the property was revalued to £500,000, and the carrying amount was £480,000 (£400,000 for buildings + £80,000 for land).

Revaluation surplus = Fair value - Carrying amount

Revaluation surplus = £500,000 - £480,000

Revaluation surplus = £20,000

Therefore, the balance on the revaluation surplus as at 30 September 2021 is £20,000.

Based on the calculations above, the correct answer is:
