if f(x)f(x) is an exponential function where f(-2.5)=1f(−2.5)=1 and f(3.5)=15f(3.5)=15, then find the value of f(-1.5)f(−1.5), to the nearest hundredth.
The value of exponential function is f(-1.5) is 1.542 (approx.)
Given that f(x)f(x) is an exponential function where
f(-2.5)=1f(−2.5)=1 and f(3.5)=15f(3.5)=15, then we need to find the value of f(-1.5)f(−1.5).
Let f(x)f(x) be an exponential function.
Let us suppose the equation for f(x) is given by
f(x) = ab^x where a is a constant of proportionality (also called the initial value) and b is the base of the exponential function.
Putting the given values in the above equation, we have1 = ab^(-2.5) ......(i)
and 15 = ab^(3.5) .......(ii)
Divide equation (i) by equation (ii), we get
1/15 = b^(3.5+2.5) => b = (1/15)^(1/6) = 0.802
The equation for f(x) can now be written as
f(x) = a(0.802)^x
Putting x = -1.5 in the above equation, we have
f(-1.5) = a(0.802)^(-1.5)f(-1.5) = 1(0.802)^(-1.5)f(-1.5) = 1.542 (approx.)
Thus, the value of f(-1.5) is 1.542 (approx.)

The amounts are x (me) and y (sister).
If I give my sister 5 dollars, then we will have the same amount of money:
x - 5 = y + 5 ⇒ x = y + 10If she gives me 8 dollars, then I'll have twice as much money as she has:

The diameter of a circle is 10 in. What is the approximate circumference? Show your work to receive
full credit. **You must include the units of measurement to receive full credit. **
The approximate circumference of a circle with a diameter of 10 inches is 31.42 inches.
To determine the circumference of a circle, we can use the formula C = πd, where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and d is the diameter of the circle. Given that the diameter is 10 inches, we substitute this value into the formula:
C = 3.14 * 10
Calculating this expression, we find:
C ≈ 31.42 inches
Therefore, the approximate circumference of the circle is 31.42 inches. It is important to note that the units of measurement are crucial in providing an accurate answer, so we include "inches" to denote the unit of measurement.

The financial statements of the Blue Spruce Corp. reports net sales of $624000 and accounts receivable of $82800 and $45600 at the beginning of the year and end of year, respectively. What is the average collection period for accounts receivable in days
The average collection period for accounts receivable in days for Blue Spruce Corp. is approximately 59.9 days.
To calculate the average collection period, we need to determine the average accounts receivable balance. We can do this by adding the beginning and ending accounts receivable balances and dividing the sum by 2. In this case, the average accounts receivable balance is ($82,800 + $45,600) / 2 = $64,200.
Next, we need to divide the net sales by the average accounts receivable balance and multiply the result by 365 (the number of days in a year). This gives us ($624,000 / $64,200) * 365 = 3.579 * 365 ≈ 1,306.135.
Therefore, the average collection period for accounts receivable is approximately 59.9 days. This means it takes Blue Spruce Corp. around 59.9 days, on average, to collect payment from its customers. A lower average collection period is generally preferable, as it indicates quicker cash flow and better liquidity for the company.

Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
Answer:
68°
Step-by-step explanation:
DE ║ BC
So, ∠DBC = ∠ADE = 62° (∵ Corresponding Angles are equal )
In triangle DEC ,
∠EDC+ ∠ECD = ∠AED (∵ Exterior Angle Sum Property of a triangle )
⇒ ∠AED = 23° + 27° = 50°
Now in triangle AED ,
∠EAD + ∠ADE + ∠AED = 180°
⇒ x° + 62° + 50° = 180°
⇒x° = 180° - 112° = 68°
Find the perimeter of the triangle
first off, something noteworthy is that we have two angles of 60°, that means that the angle atop is also 60°, so we really have an equilateral triangle, with an altitude or height as shown above, so

If PQRS and TSUV are congruent parallelograms, which angle in parallelograms TSUV is congruent to ∠PQR?
The PQRS and TSUV are congruent parallelograms, they have the same shape and size. angle PQR is congruent to angle TSU, since they are opposite angles in parallelograms PQRS and TSUV, respectively. so angle TSU in parallelogram TSUV is congruent to angle PQR.
What distinguishes a parallelogram?The following are a parallelogram's characteristics:
The two opposing sides are level and parallel.
The opposing angles line up evenly.
The following or adjacent angles are extra.
Every angle will be at a right angle if even one of the other angles is.
PQRS and TSUV are congruent parallelograms, which denotes that their dimensions are the same. The parallelograms' corresponding angles are therefore equal.
Angle PQR is an interior angle in the parallelogram PQRS that is opposite to the adjacent angle PQS, whereas angle UTS is an internal angle in the parallelogram TSUV that is opposite to the adjacent angle TSV.
We can infer that angle PQR and angle UTS are related angles and are hence congruent because PQRS and TSUV are congruent.

Round your answer to the nearest tenth.
suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.56 and a standard deviation of 0.45. using the empirical rule, what percentage of the students have grade point averages that are greater than 2.11? please do not round your answer.
By using empirical rule, approximately 34% of the students have grade point averages that are greater than 2.11.
The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.
We want to find the percentage of students with a GPA greater than 2.11. To do so, we need to calculate the number of standard deviations that separate 2.11 from the mean of 2.56:z = (2.11 - 2.56) / 0.45 = -1
Here, z represents the number of standard deviations away from the mean. A negative z-value indicates that the value of interest is below the mean.
Now that we have calculated the z-value, we can use the empirical rule to determine the percentage of students with a GPA greater than 2.11. Since the value of interest is below the mean, we need to calculate the percentage of students who fall within one standard deviation below the mean:
68% - 34% = 34%

1 poi (6) Jason's part-time job pays him $105 a week. If he has already saved $325, what is the minimum number of weeks he needs to work in order to have enough money to buy a dirt bike for $900?
We are told that Jason has $325 and that he earns $105 per week. That means that if "w" is the number of weeks then the amount of money he has in total is what he has saved by the product of $105 by the number of weeks. That is, if A is the amount he has, then:
\(A=325+105w\)Now, we are asked how many weeks it takes to get to $900. This means that we set A = 900 and solve for "w".
\(900=325+105w\)To solve for "w" we first subtract 325 on both sides:
\(\begin{gathered} 900-325=325-325+105w \\ 575=105w \end{gathered}\)Now we divide both sides by 105
\(\frac{575}{105}=\frac{105w}{105}\)Solving the operations:
\(5.5=w\)Therefore, it takes Jason 5.5 weeks to get to $900

Work out the value of A.
The area of triangle (A) is 210 cm².
What is the area of the triangle and perimeter of the triangle?
If a, b, and c are the sides of the triangle, then
Perimeter of the triangle = (a + b + c) units.
Area of the triangle = \(\sqrt{(s(s - a) (s - b) (s - c)) }\)
The semi-perimeter of the triangle, s = (a + b + c)/2
Let the triangle is ABC,
and AB = 3x - 1, BC = 4x + 1 and AC = 3x.
Perimeter = 70
AB + BC + AC = 70
3x-1 + 4x + 1 +3x = 70
10x = 70
x = 7
AB = a = 3x - 1 = 20
BC = b = 4x + 1 = 29
AC = c = 3x = 21
Now semi-perimeter = s = 70/2
s = 35
Area of the triangle = \(\sqrt{(s(s - a) (s - b) (s - c)) }\)
\(=\sqrt{35(35-20)(35-29)(35-21)}\\\\\\=\sqrt{35(15)(6)(14)}\\\\=\sqrt{44100}\\\\=210\)
Area of the triangle = 210 square cm.
Hence, the area of triangle (A) is 210 cm².
