Step-by-step explanation:
v=2/3pir^32/3×22/7×26.7^3837503.17÷21=39881.103m^3answer is 39881.1 since the hundredths value is less than 5write the equation of an exponential function that passes through the points (2,48) and (5,750).
Answers
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x
The equation of an exponential function will be y = 7.68 × 2.5ˣ.
What is equation of line?
The equation of line with slope m and passes through the point (x₁, y₁) is calculated as;
y - y₁ = m (x - x₁)
Given that;
An exponential function passes through the points (2, 48) and (5, 750).
Now, The exponential function is;
y = abˣ
Where, a and b are unknowns.
Hence, For the point (2, 48), we get the equation;
48 = ab² .. (i)
And, For the point (5, 750), we get;
750 = ab⁵ .... (ii)
Solve the equation (i) for value of a, we get;
48 = ab²
a = 48/b²
Substitute in equation (ii);
750 = ab⁵
750 = (48/b²) b⁵
750 = 48 b³
b³ = 750/48
Take cube root both side;
b = 5/2
Hence, a = 48/b² = 48/(5/2)²
a = 48 × 4 / 25
a = 7.68
Thus, After substitute the value of a and b we get the exponential equation as;
y = 7.68 × 2.5ˣ
Therefore, The equation of an exponential function will be,
⇒ y = 7.68 × 2.5ˣ.

Answers
Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.
The formula for probability of getting an event is given by :
[tex]P=\dfrac{Favourable\ outcome}{Total\ no\ of\ outcomes}[/tex]
Here, favourable outcome = 1
Total outcomes = 8
So,
[tex]P=\dfrac{1}{8}[/tex]

Find the value of y.
120°
Answers
Answer:
y = 60°
Step-by-step explanation:
The tangent- chord angle y is half the measure of its intercepted arc , then
y = [tex]\frac{1}{2}[/tex] × 120° = 60°
The value of y is 60 °
What is the tangent- chord angle theorem?"The angle generated by a tangent to a circle and a chord is equal to half the angle measure of the intercepted arc," is another way to state the Tangent-Chord theorem. Since the angle measure of an intercepted arc is double that of the inscribed angle that subtends it, this is equivalent to what we have demonstrated.The measure of an angle formed by a tangent and a chord meeting at the point of tangency is half the measure of the intercepted arc.Given , the angle is 120°
Now apply the tangent- chord angle theorem, " a chord meeting at the point of tangency is half the measure of the intercepted "
y = 1/2 × 120°
y = 1/2 × 120° = 60°
Therefore, the value of angle y is 60°.

Habiendo salido el 84% de los alumnos de un colegio, permanecen en el mismo 20 alumnos. ¿Cuántos alumnos salieron del colegio?
Answers
Answer:
105 students
Step-by-step explanation:
The computation of the number of students left the school is given below:
Let us assume the total students be x and 100%
Left percentage = 84%
Remaining percentage = 100% - 84% = 16%
Now according to the question
16% of x = 20
0.16x = 20
x = 20 ÷ 0.16
x = 125
Total students 125
Those who left is
= 84% of 125
= 105 students

Step-by-step explanation:
A running track design is composed of two half circles connected by two straight-line segments. Garrett is jogging on the inner lane (with radius r) while Devin is jogging on the outer (with radius R). If r= 30 meters and R= 33 meters, how much longer does Devin have to run to complete one lap?
Answers
Answer:
18.86 m
Step-by-step explanation:
From the given question, both covers the same distance of the straight line segment.
For the inner lane,
length of arc of its semicircle = [tex]\pi[/tex]r
= 30 x [tex]\frac{22}{7}[/tex]
= 94.2857
So that,
the total length for the two halves of the inner lane = 2 x 94.2857
= 188.5714 m
For the outer lane,
length of arc of its semicircle = [tex]\pi[/tex]r
= 33 x [tex]\frac{22}{7}[/tex]
= 103.7143
The total length for the two halves of the outer lane = 2 x 103.7143
= 207.4286 m
The difference between the two = 207.4286 - 188.5714
= 18.8572 m
Therefore, Devin would run 18.86 m more to complete one lap.
