Answer:
$5,674.30
Step-by-step explanation:
Use the Compound Amount formula:
A = P(1 + r/n)^(n*t), where r = APR as a decimal fraction = 0.1499
and n = 12 (compounded monthly).
Then A = $2,000(1 + 0.1499/12) )^(7*12)
= $2,000(1 + 0.0125)^84
= $2,000(1.0125)^84 = $2,000(2.837) = $5,674.30

Lin says that the inequalities h>150 and h<160 describe her height in centimeters. what do the inequalities tell us about her height?
Answer:
Her height is in between 150 and 160
Step-by-step explanation:
Given
h > 150
h < 160
Required
What do these represent?
First, the inequalities need to be combined.
If h < 160, then this means that 160 > h.
So, h > 150 and 160 > h can be combined to form an inequality in the following form;
160 > h > 150
This.meeans 160 is greater than h and h is greater than 150.
If this is related to her height, it means 160 is greater than her height and her height is greater than 150;
In other words, her height is in between 150 and 160
A certain shampoo is available in two sizes. A 23.7-ounce bottle costs $4.97 . A 33.8 -ounce bottle costs $7.48 . Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.
Unit price for the 23.7 Price per ounce
33.8 Price per ounce
Answer:
23.7 ounce = 20 cents per ounce
33.8 ounce = 22 cents per ounce
The 23.7 ounce bottle is a better deal because it is only 20 cents per ounce, rather than 22 cents per ounce.

explain how the formula for the volume of a cone is derived
Answer:
The volume of a cone is 1 3 π r 2 h \frac { 1 } { 3 } \pi r ^{ 2 } h 31πr2h, where r denotes the radius of the base of the cone, and h denotes the height of the cone.
Step-by-step explanation:
(happy to help)
Final answer:
The volume of a cone is derived using the principle of integrating infinitesimally thin discs along the height of the cone, given by the formula V = ⅓πr²h.
Explanation:
The formula for the volume of a cone is derived using calculus and geometric principles. Consider a cone generated by rotating a line around one of the coordinate axes. If we know the formula for the area A of a circle, it can be extended to find the volume of a cone. The area A of a circle is πr², where r is its radius. The formula for the volume V of a cone is ⅓ × base area × height, which can be expressed as V = ⅓πr²h, with h being the cone's height.
Using integral calculus, the cone's volume is found by stacking infinitesimally thin discs (each with volume πr²dx, where dx is the disc's thickness) along the cone's height. The radius r changes linearly from the base to the apex, following the relationship r = (h - x)tan(a), where a is the semivertical angle of the cone. Thus, you integrate from the apex (0) to the base (h) to find the entire volume of the cone.
An Ice Hockey rink is a rectangle with a perimeter of 174 meters. The length is 9 meters more than twice the width. What equation describes this problem? (Remember that the perimeter is twice the length plus twice the width)
Answer:
Let width be x metres
so, length is "9 metres more than twice the width" --> 9+2x
So, perimeter is x + x + (9+2x) + (9+2x) = 174
6x + 18 = 174
6x = 156
x = 156/6
x = 26m
width = 26m
length is therefore 9+2(26) --> 9+52 --> 61m

The Cole family owns an above-ground circular swimming pool that has walls made of aluminum. Find the length (l) of aluminum surrounding the pool as shown if the radius is 15 feet. (use π=3.14 )
Answer:
The length of aluminium surrounding the pool is 94.20 ft.
Step-by-step explanation:
The picture represents the circular swimming pool that has walls of aluminium surround it.
The circumference of a circle is the distance around a circle. It is the curved line that goes round the circle. The question wants us to find the circumference of the aluminium surrounding the circular pool.
circumference of a circle = 2πr
circumference of a circle = 2 × 3.14 × 15
circumference of a circle = 30 × 3.14
circumference of a circle = 94.2 ft
The length of aluminium surrounding the pool is 94.20 ft.

There are 8 baseball players in the dugout for practice. Each player shakes hands with each of the other player ONLY ONCE.
How many handshakes are there?
Explanation:
There are 8 players. For each player, there are 7 people to shake hands with. So we have 8*7 = 56 handshakes so far; however, we double count since the sequence AB is the same as BA (where A and B are player names). Order does not matter when it comes to shaking hands. So we have to divide by 2 to fix the double count. We go from 56 to 56/2 = 28. There are 28 different combinations.
You can use the formula [tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex] with n = 8 and r = 2, but the formula is a bit confusing to be honest if you aren't familiar with it. The exclamation marks indicate factorials.
Extra info: The value 28 can be found in Pascals triangle. Look at the row that starts with 1, 8, ... then note how 28 is in the third slot. Keep in mind that you start at r = 0 and count up by 1. So r = 2 corresponds to the third slot.

A circle has the equation x2−12x+27=−y2+8y.
What is the equation of the circle in standard form, the location of its center, and the length of its radius?
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (6,4), and the radius is 5 units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (6,4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (−6,−4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (−6,−4), and the radius is 5 units.
Answer:
It's the first option.
Step-by-step explanation:
x^2 - 12x + 27 = - y^2 + 8y
x^2 - 12x + y^2 - 8y = -27 Completing the squares:
(x - 6)^2 - 36 + (y - 4)^2 - 16 = -27
(x - 6)^2 + (y - 4)^2 = -27 + 36 + 16
(x- 6)^2 + (y - 4)^2 = 25 is the standard equation.
The center is at (6, 4) and the radius is 5 units.
Answer:
first option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² - 12x + 27 = - y² + 8y ( subtract - y² + 8y from both sides )
x² - 12x + y² - 8y + 27 = 0 ( subtract 27 from both sides )
x² - 12x + y² - 8y = - 27
Using the method of completing the square on both the x and y terms
add ( half the coefficient of the x/ y term )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 4)y + 16 = - 27 + 36 + 16
(x - 6)² + (y - 4)² = 25 ← in standard form
with centre = (6, 4 ) and r² = 25 ⇒ r = [tex]\sqrt{25}[/tex] = 5 → first option
