A rectangular prism with a length of 3.8 meters and a width of 1.5 meters has a volume of 16.53 cubic meters.
What is the height of the prism?
2.9 m
6.525 m
11.23 m
21.83 m
Answer:
2.9 meters.
Step-by-step explanation:
First we multiply the length, 3.8, by the width, 1.5, to get the base, 5.7 (this step is not entirely necessary, but makes it much easier). Then we divide the volume, 16.53, by the base, 5.7, to get the height, 2.9 meters.

The indicated side of the right triangle is [tex]44\sqrt{2} =\frac{88}{\sqrt{2} }[/tex].
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says:[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]. And the main trigonometric ratios are:
[tex]sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\[/tex]
The question asks to find one of the legs (y). Then, you can find y applying the trigonometric ratio (sin 45°).
[tex]sin(45\°)=\frac{y}{88}[/tex]
Like sin45° is equal to [tex]\frac{\sqrt{2} }{2}[/tex], you have
[tex]\frac{\sqrt{2} }{2} =\frac{y}{88}\\ \\ 2y=88\sqrt{2} \\ \\ y=44\sqrt{2} \\ \\ Thus\\ \\ y=\frac{88}{\sqrt{2}}[/tex]

The first term of a geometric sequence is 2, and the 4th term is 250. Find the 2 terms between the first and the 4th term.
Answer:
second term: 10
third term: 50
Step-by-step explanation:
The equation for any geometric sequence is [tex]a_{n} = a_{1} *r^{n-1}[/tex] where n is the term number you want to find, [tex]a_{1}[/tex] is the first term in the sequence, and [tex]r[/tex] is the common ratio. The equation for this sequence specifically uses 5 as its common ratio, so the equation is [tex]a_{n} =2*5^{n-1}[/tex]
[tex]a_{1} = 2*5^{1-1}=2*5^{0} =2*1=2[/tex]
[tex]a_{2} = 2*5^{2-1}=2*5^{1} =2*5=10[/tex]
[tex]a_{3} = 2*5^{3-1}=2*5^{2} =2*25=50[/tex]
[tex]a_{4} = 2*5^{4-1}=2*5^{3} =2*125=250[/tex]

Step-by-step explanation:
. In Figure 5.144, of ΔABC, where
m(∠C) = 30, m(∠ABD) = 5x,
m(∠A) = 4x. Find m(∠ABC) in
degrees.
Find the center and radius of the circle with this equation:
x² + 16x + 64 + y² - 2y + 1 = 144
By completing squares, we will see that the radius is 12 units and the center is (-8, 1).
How to find the center and radius of the circle?The circle of center (x₁, y₁) and radius r is written as:
(x - x₁)² + (y - y₁)² = r²
Now we go to our equation:
x² + 16x + 64 + y² - 2y + 1 = 144
Now we need to complete squares:
(a + b)² = a² + 2ab + b²
Then we can rewrite:
(x² + 2*8*x + 8*8) + (y² - 2y + 1) = 12²
(x + 8)² + (y - 1)² = 12²
So the center is the point (-8, 1) and the radius is 12 units.

A tub of water is emptied at a rate of 3 gallons per minute. The equation y –12 = –3(x – 1) models the amount of water remaining, where x is time (in minutes) and y is the amount of water left (in gallons). Analyze the work shown below to determine the initial amount of water.
1. Solve for the y-variable.
y – 12 = –3(x – 1)
y – 12 = –3x + 3
y = –3x +15
2. Write the equation using function notation.
f(x) = –3x +15
The tub started with
gallons of water.
The initial amount of the water is 15 gallons
Linear functionsThese are functions that has a leading degree of 1. Given the equation that represents the amount of water remaining after x minutes;
y - 12 = -3(x- 1)
y -12 = -3x + 3
y = -3x +3 + 12
y = -3x + 15
In order to determine the initial amount of water, we will substitute x =0 into the function
y = -3(0) + 15
y = 15
Hence the initial amount of the water is 15 gallons

The graph of y=x² + 11x + 24 is equivalent to the graph of which equation?
y=(x+8)(x+3)
y=(x + 4)(x+6)
y=(x +9)(x + 2)
y=(x + 7)(x+4)
Answer:
y = (x+8)(x+3)
Step-by-step explanation:
If you multiply
(x+8)(x+3),
you get x^2 + 3x + 8x + 24
This simplifies to x^2 + 11x + 24, same as the original question.
The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Constants and variables are components of a polynomial.
We have Graph whose equation is
y=x² + 11x + 24
Now, factories the above equation using splitting the middle term
y=x² + 11x + 24
y=x² + 8x + 3x + 24
y = x(x+8) + 3(x+8)
y= (x+3)(x+8)

Casho invests money in an account paying simple interest. She invests $30 and no
money is added or removed from the investment. After one year, she has $32.40.
What is the simple percent interest per year?
Answer:
8%
Step-by-step explanation:
Divide ( 32.40 / 30 ). This outputs the answer 1.08, or 108%. This means that the outcome is 108% of the original, or 8% greater.
The simple interest in which Casho invests money was 8%.
What is simple interest?
Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, p = 30, SI = (32.40 - 30) = $2.40 and t = 1.
Therefore, 2.40 = (30×r×1)/100.
240 = 30r.
r = 240/30.
r = 24/3.
r = 8.
So, The rate of simple interest is 8%.
