A large asteroid crashed into a moon of another planet causing several boulders from the moon to be propelled into space toward the planet. Astronomers were able to measure the speed of one of the projectiles. The distance (in feet) that the projectile traveled each second, starting with the first second, was given by the arithmetic progression 18,54, 90,126, . Find the distance that the projectile traveled in the eighth second.
Answers
Answer:
270 feet
Step-by-step explanation:
From the sequence given, we can see that the asteroid travels 36 feet more with each second. (as seen [tex]54-18=36[/tex] and [tex]90-54=36[/tex] etc.)
So 5th second, it will travel: [tex]126+36=162[/tex]
6th second, it will travel: [tex]162+36=198[/tex]
7th second, it will travel: [tex]198+36=234[/tex]
8th second, it will travel: [tex]234+36=270[/tex]
Hence, in the eighth second, the projectile traveled 270 feet.
The distance the projectile travels in the eighth second is found to be 270 feet.
The question asks for the distance a projectile travels in the eighth second, given that the distances it covers each second form an arithmetic progression with initial distances given as 18, 54, 90, 126, etc. In an arithmetic progression, the difference between any two consecutive terms is constant, known as the common difference.
To find the common difference (d), we subtract the first term from the second term:
d = 54 - 18 = 36
The nth term of an arithmetic sequence can be found using the formula:
T(n) = a + (n - 1)d
Here, a represents the first term, which is 18, and d is the common difference we found to be 36. Substituting the values to find the eighth term:
T(8) = 18 + (8 - 1) x 36T(8)
= 18 + 7 x 36T(8)
= 18 + 252T(8) = 270
Thus, the distance the projectile travels in the eighth second is 270 feet.

$125
The original selling price if, A dress is selling for $100 after a 20 percent discount is $125.
What is the percentage?
A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.
Given:
A dress is selling for $100 after a 20 percent discount,
Calculate the original price as shown below,
Original price - 20% original price = 100
Original price(1 - 0.2) = 100
Original price = 100 / 0.8
Original price = $125
Thus, the original price is $125.

WXYZ is a kite. If the measure of angle WXY is 120°, the measure of angle WZY is 4x° and the measure of angle ZWX is 10x°, find the measure of angle ZYX.
Answers
Answer:
100 degrees
Step-by-step explanation:
Remark
The endpoints of the smaller diagonal of a kite, intersect the vertexes of 2 equal angles. Put in simpler language, if x is at the top of the kite and x is the vertex of the larger angle between the top and bottom angles, then the other two angles (left and right) are equal.
In still simpler language. <W = <Y
Equation
<X + <W + <Z + <Y = 360 All quadrilaterals have 360 degrees for their interior angles.
Givens
<X = 120<W = 10x<Z = 4x <Y = 10xSolution
120 + 10x + 10x + 4x = 360 Gather like terms on the left120 + 24x = 360 Subtract 120 from both sides120- 120 + 24x = 360 - 120 consolidate 24x = 240x = 10Answer
Since <ZYX = 10x<ZYX = 10*10 = 100 degrees.Answer:
100
Step-by-step explanation:
Angle ZWX and angle ZYX are congruent.
360 = 120 + 4x + 10x + 10x
360 = 120 + 24x
240 = 24x
10 = x
The measure of angle ZYX is equal to 10(10) = 100°
Iva deposits $2,000 into an interest-bearing savings account that is compounded continuously at an interest rate of 5%. She decides not to deposit or withdraw any money after the initial deposit. We can represent the account balance of the savings account after t years by an exponential function:
A(t) = $2,000 ∙ e^0.05t.
Approximately how many years will it take for the initial deposit to double?
Answers
Answer:
13.863 years
Step-by-step explanation:
Initial deposit is $2,000.
The rate of interest is 5% compounded continuously.
The account balance of the savings account after t years by an exponential function:
A(t) = $2,000 ∙ e^0.05t.
It says to find out the time when it takes for the initial deposit to double, i.e. A(t) = $4,000
Mathematically, we can set them equal and solve for t as follows:-
A(t) = $2,000 ∙ e^0.05t = $4,000.
e^(0.05t) = 4000/2000 = 2
0.05t Ln(e) = Ln(2)
t/20 = Ln(2)
t = 20 * Ln(2) = 13.86294361
So, it takes 13.863 years for the initial deposit to double.

b.) there would be 0 obtuse angles.
c.) there would be 1 right angle.
In the diagram you can see a little black box in one of the corners of the triangles. That box means the angle is a right, 90 degree angle. Since an acute angle is an angle that is less than 90 degrees, and since all three angles would have to add up to 180 degrees, you know that the other two angles are acute angles.
Answer:
10. 1 right 2 acute 0 obtuse angles
11. x=6
Step-by-step explanation:
10. A triangle has 3 angles.
If it is a right triangle is has 1 right angle which is 90 degrees.
90 + x+y = 180 where x and y are the other 2 angles
Subtract 90 from both sides
x+y = 90
So the 2 angles that are left can only add to 90.
An obtuse angle is greater than 90 degrees, so we cannot have an obtuse angle. Acute angles are less than 90 degrees.
A right angle is 90 degrees. If one of the angles left is 90 degrees, the other one is zero, and that does not make a triangle.
So we must have 1 right angle and 2 acute angles (no obtuse angles)
11. Since the 2 sides are the same the triangle is isosceles. That means the two angles have the same measurements.
90 + y+y = 180
y+y=90
2y = 90
y = 45
Each angle must equal 45 degrees
7x+3 = 45 degrees
Subtract 3 from each side
7x+3-3 =45-3
7x =42
Divide each side by 7
7x/7 =42/7
x =6

A rectangle is inscribed in a semicircle of radius 8 cm. What is the maximum area of the rectangle?
Answers
The maximum area of a rectangle inscribed in a semicircle of radius 8 cm is found by maximizing the product of its width and height, which occurs when the rectangle's height is half the radius. Using the Pythagorean theorem, the optimal dimensions are calculated, leading to a maximum area of approximately 27.71 cm².
Explanation:To find the maximum area of a rectangle inscribed in a semicircle of radius 8 cm, we can employ a geometrical approach. Let the width of the rectangle be w and the height h. Because the rectangle is inscribed in a semicircle, the diagonal of the rectangle will be the radius of the semicircle, and the width of the rectangle will span from the midpoint of the diameter to a point on the circumference of the semicircle. Given the Pythagorean theorem, we have w² + h² = (2r)², where r is the radius. For our case, r = 8 cm.
Maximum area occurs when the rectangle's area is maximized. The area of the rectangle is A = w × h. By using the relation obtained from the Pythagorean Theorem, and knowing that for a rectangle inscribed in a semicircle the height will be half the radius when the area is maximized, we find h = r/2 = 4 cm. Substituting back into the Pythagorean Theorem, we find w = √(8² - 4²) = √64 - 16 = √48 = 4√3 cm. Therefore, the maximum area of the rectangle is A = w × h = 4√3 × 4 = 16√3 cm². This is approximately 27.71 cm².
This question combines geometry and basic principles of optimization to find the maximum area of a geometric shape within defined constraints, showcasing the application of mathematical reasoning in problem-solving.

Diagonal AC divides the trapezoid ABCD (with bases AD and BC, AD>BC) into two similar triangles, △ABC and △DCA. Find AC if BC=4 cm and AD=9 cm.
Answers
Answer:
6 cm
Step-by-step explanation:
Let k represent the scale factor between ΔABC and ΔDCA. Then ...
... CA = k·BC
... AD = k·CA
So, AD/BC = k·(k·BC)/BC = k² = 9/4
Then k = √(9/4) = 3/2, and ...
... CA = (3/2)·BC = (3/2)·(4 cm)
... CA = 6 cm
Final answer:
To find the length of diagonal AC in trapezoid ABCD, we utilize the properties of similar triangles created by the diagonal. Since triangles △ABC and △DCA are similar, we set up a proportion using the sides BC and AD, and solve for AC to find that AC is 6 cm.
Explanation:
The question asks us to find the diagonal AC of trapezoid ABCD where it's given that BC = 4 cm and AD = 9 cm, and triangles △ABC and △DCA are similar. To find AC, we can use the properties of similar triangles which dictate that corresponding sides are proportional. Let us consider that the trapezoid is split into two triangles by AC. The ratio of the smaller triangle's base to the larger triangle's base (BC:AD) must be the same as the ratio of any other pair of corresponding sides in these two similar triangles. Furthermore, the ratio of the longer leg of △ABC (which is AC) to its base BC is equal to the ratio of the longer leg of △DCA (which is also AC) to its base AD. Using these ratios, we can set up a proportion to solve for AC:
AC/BC = AC/AD
Since the length of AC is the same in both ratios, we can multiply both sides by BC*AD to get:
[tex]AC^2 = BC * AD[/tex]
By substituting the given values for BC and AD into the equation we get:
[tex]AC^2 = 4 cm * 9 cm[/tex]
[tex]AC^2 = 36 cm^2[/tex]
To find AC, we take the square root of both sides:
AC = √36 cm
AC = 6 cm
Hence, the length of diagonal AC is 6 cm.

A ball is dropped from a heigh of h feet and repeatedly bounces off the floor. After each bounce, the ball reaches a height that is 2/3 of the height feom which it oreviously fell. For example, after the first bounce, the ball reaches a height of 2/3h feet. What represents the total number of feet the ball travels between the firat and the sixth bounce?
Answers
Answer:
[tex]s = \sum^5_1 {(2h)(\frac{2}{3})^i},[/tex]
Step-by-step explanation:
The initial height of the ball is h
After the first bounce the height is [tex]\frac{2}{3}h[/tex]
After the second bounce the height is [tex]\frac{2}{3}(\frac{2}{3})h[/tex]
After the i-th rebound the height is [tex](\frac{2}{3}) ^ i[/tex]
Then, distance s traveled by the ball is the sum of the heights reached between the first and fifth bounces.
[tex]s = 2 [\frac{2}{3}h + \frac{2}{3}(\frac{2}{3})h +, ..., + (\frac{2}{3}) ^ n h][/tex]
The equation is multiplied by 2 because the distance the ball travels when it goes up is the same as it travels down.
Finally the distance is a geometric series as shown:
[tex]s = \sum^5_1 {(2h)(\frac{2}{3})^i},[/tex]
The total distance traveled by the ball between the first and sixth bounce is [tex]\( \frac{23}{3}h \)[/tex] feet.
Step 1: Find the distance traveled during the first fall:
- The ball is dropped from a height of [tex]\( h \)[/tex] feet.
- So, the distance traveled during the first fall is [tex]\( h \)[/tex] feet.
Step 2: Find the distance traveled during each subsequent bounce:
- After each bounce, the ball reaches a height that is [tex]\( \frac{2}{3} \)[/tex] of the height from which it previously fell.
- During each bounce, the ball travels twice the distance of the height it reached.
- Therefore, during each bounce, the total distance traveled is [tex]\( \frac{4}{3}h \)[/tex] feet.
Step 3: Find the total distance traveled between the first and sixth bounce:
- Since we're asked for the distance between the first and sixth bounce, we have 5 subsequent bounces.
- The total distance traveled between the first and sixth bounce is the sum of the distance traveled during the first fall and the total distance traveled during the subsequent five bounces.
- So, it's [tex]\( h + 5 \times \left(\frac{4}{3}h\right) \)[/tex]feet.
Step 4: Calculate the total distance:
- Substitute the values and calculate: [tex]\( h + \frac{20}{3}h = \frac{23}{3}h \)[/tex]feet.
Therefore, the total number of feet the ball travels between the first and sixth bounce is [tex]\( \frac{23}{3}h \).[/tex]

Step-by-step explanation:
2134/12=177.83
Lisa can place 177 buttons into each jar when she distributes 2,134 buttons equally among 12 jars.
Explanation:To determine the number of buttons Lisa can distribute into each jar, we perform a simple division: dividing her total button count, 2,134, by the number of jars, which is 12. This calculation results in approximately 177.83 buttons per jar. However, since you can't have a fraction of a button, we must round down to the nearest whole number, which is 177. Consequently, each jar will be filled with exactly 177 buttons. This fair distribution ensures that all 12 jars are equally supplied, making it practical and straightforward for Lisa to organize her collection.
