A rectangle has lengths of 10 and 14. A similar rectangle might have side lengths of:
Select all that apply
11 and 14
15 and 21
9 and 18
16 and 20
A rectangle is similar to another rectangle if its corresponding angles are congruent, and its sides are proportional.
To check if 11 and 14 could be the side lengths of a similar rectangle, we can set up the proportion:
10/14 = 11/x
Simplifying this proportion, we get:
5/7 = 11/x
Multiplying both sides by x, we get:
5x/7 = 11
Multiplying both sides by 7/5, we get:
x = 77/5
So, 11 is not a possible side length for a similar rectangle with side lengths 10 and 14.
Similarly,
To find the side lengths of a similar rectangle, we can set up a proportion:
10/14 = x/21
Simplifying this proportion, we get:
5/7 = x/21
Multiplying both sides by 21, we get:
x = 15
So, the side lengths of the similar rectangle are 15 and 21.

A quadratic equation, y = ax^2 - 6x + 10, has exactly one real root. Calculate the value of a.
Answer:
a = 0.9
Step-by-step explanation:
For the quadratic equation \(\boxed{ax^2 + bx + c = 0}\) to have exactly one real root, the value of its discriminant, \(\boxed{b^2 - 4ac}\), must be zero.
For the given equation:
\(y = ax^2 - 6x + 10\),
• a = a
• b = -6
• c = 10.
Substituting these values into the formula for discriminant, we get:
\((-6)^2 - 4(a)(10) = 0\)
⇒ \(36 - 40a = 0\)
⇒ \(36 = 40a\)
⇒ \(a = \frac{36}{40}\)
⇒ \(a = \bf 0.9\)
Therefore the value of a is 0.9 when the given quadratic has exactly one root.

Find the radius and diameter of each of the circles .
Answer:
Step-by-step explanation:
Diameter of the Circle refer to a line passing through the centre and meets the circumference at opposite ends. And it twice as long as Radius.
1) Radius is given 3yd
so, diameter is double of radius 2*3=6yd
Radius= 3yd
Diameter=6yd
2) Diameter is given 92 in
so, radius is half of diameter 92/2= 46 inch
Radius= 46 in
Diameter= 92 in
3) Radius is given 23 ft
so, diameter is double of radius 23*2 = 46 ft
Radius = 23 ft
Diameter = 46 ft
4) Diameter is given 36 in
so, radius is half of diameter 36/2 = 18 in
Radius = 18 in
Diameter = 36 in
5) Radius is given 19 ft
so, diameter is double of radius 19*2 = 38 ft
Radius = 19 ft
Diameter = 38 ft
6) Diameter is given 12yd
so, radius is half of diameter 12/2 = 6yd
Radius = 6yd
Diameter = 12yd

Step-by-step explanation:
Using the pythagorean theorem, we can solve to find C.
a^2 + b^2 = c^2
So it will be 15^2 + 20^2 = c^2
Simplify:
225 + 400 = c^2
625 = c^2
Square root both sides of the equation and you will get:
25 = c
c = 25
(a) The length of the unknown side is 25 yd
For perimeter, just add 20 + 15 + 25
(b) So the perimeter is 60 yd
The formula for area of a triangle is:
Area = (Base x Height) / 2
Now, we can plug in the numbers.
Base = 15
Height = 20
(15 x 20) / 2
300 / 2
= 150
(c) The area of the triangle is 150yd^2

in 1932, giuseppe momo was commissioned to build the famous vatican museum double spiral staircase. suppose that it takes you one hour to stroll at a constant speed up one spiral of this staircase, which has a radius of 19 feet and a height of 40 feet and makes 4 revolutions. (a) assuming the spiral staircase is centered about the -axis, find a vector parametric equation for the helical path you take from the point to the point that makes revolutions during the time interval .
where r = 19 feet, h = 40 feet, and θ varies from 0 to 8π (4 complete revolutions) as t varies from 0 to 4.
What is equation?An equation is a mathematical statement that shows the equality of two expressions, which are separated by an equals sign (=). An equation can have variables, constants, coefficients, and operators. The variables are represented by letters, and their values can change depending on the context of the problem. The constants are fixed values, and the coefficients are the numbers that multiply the variables. The operators are mathematical symbols that indicate the operation to be performed, such as addition (+), subtraction (-), multiplication (*), division (/), and exponentiation (^). Solving an equation means finding the value(s) of the variable(s) that satisfy the equation.
Given by the question.
Let's start by defining the necessary parameters. The radius of the staircase is given as 19 feet, and the height is given as 40 feet. The staircase makes 4 complete revolutions, so the total height of the staircase is 4 times the height of one revolution, which is 40 feet.
To find a vector parametric equation for the helical path, we need to consider the circular motion around the center axis, as well as the motion along the axis. Let's define the following parameters:
r: radius of the staircase (19 feet)
h: height of one revolution (40 feet)
θ: angle of rotation around the center axis (in radians)
z: height along the center axis
The circular motion around the center axis can be described by the following parametric equation:
x = r cos(θ)
y = r sin(θ)
z =???
To find the equation for z, we need to consider the motion along the center axis. Since it takes one hour to stroll up one revolution, and there are 4 revolutions in total, the time it takes to stroll up the entire staircase is 4 hours. Therefore, we can use t as a parameter that varies from 0 to 4, and define z as:
z = (h/4) t
Note that we divide h by 4 to scale the parameter t to the interval [0,4].
Putting it all together, the vector parametric equation for the helical path is:
r(t) = <r cos(θ), r sin(θ), (h/4) t>

What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (-3, 1)?
Answer:
y-1= -1/3(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
y-1=m(x+3)
the slope is rise over run
the slope is -1/3
Answer:
y - 1 = 3/2 (x + 3)
Step-by-step explanation:
To find the equation of a line parallel to the given line and passing through the point (-3, 1), we can use the point-slope form of a linear equation. The point-slope form is given by:
y - y₁ = m(x - x₁)
Where (x₁, y₁) is the given point and m is the slope of the line.
First, let's calculate the slope of the given line using the two points (-2, -4) and (2, 2):
slope = (y₂ - y₁) / (x₂ - x₁)
= (2 - (-4)) / (2 - (-2))
= 6 / 4
= 3/2
Since the line we want to find is parallel to the given line, it will have the same slope. Therefore, the slope (m) of the new line is also 3/2.
Now we can substitute the values into the point-slope form using the point (-3, 1):
y - 1 = (3/2)(x - (-3))
y - 1 = (3/2)(x + 3)
The equation in point-slope form of the line parallel to the given line and passing through the point (-3, 1) is:
y - 1 = 3/2 (x + 3)

1. An acrobat is on a platform that is 25 feet in the air. She jumps down
at an initial vertical velocity of 4 ft/s. Write a quadratic function to
represent the height h of the acrobat t seconds after the jump.
If a safety net is placed 5 feet above the ground, how long will it take
for her to land safely on the net?
It will take the acrobat 1/4 of a second to land safely on the net.
What is velocity?Velocity is a physical quantity that measures the rate at which an object moves in a particular direction. It is measured in terms of distance traveled per unit of time, usually expressed in terms of meters per second (m/s). Velocity is a vector quantity, meaning it has both a magnitude and a direction. It is an important concept in physics and is used to understand the motion of objects and forces.
The quadratic equation representing the height h of the acrobat t seconds after the jump can be written as follows: \(h=-16t^2+4t+25\).
To find the time it takes for the acrobat to land safely on the net, we need to solve for t when h=5. We can do this by substituting 5 for h into the equation and solving for t:
\(h=-16t^2+4t+25\\\\5=-16t^2+4t+25\\\\=-16t^2+4t-20=0\\\\(4+\sqrt{64})/(-32)=t\\ \\t=(4+8)/(-32)\\\\t=1/4\)

x + 7y = 21
x + 4y = 15
Solve the simultaneous equations
Answer:
x = 7, y = 2
Explanation:
equations given:
x + 7y = 21
x + 4y = 15
make "x" the subject:
x + 7y = 21
x = 21 - 7y .........equation 1
x + 4y = 15
x = 15 - 4y .......equation 2
Solving both the equations simultaneously:
15 - 4y = 21 - 7y
-4y + 7y = 21 - 15
3y = 6
y = 6 ÷ 3
y = 2
If y is 2
Then x = 21 -7y;
x = 21 - 7(2)
x = 21 - 14
x = 7
x + 7y= 21
7 goes to RHS = X+ y = 21/7-3
x + 4y = 15
4 goes to RHS= x+y = 15/4 = 3.75

D, \(\frac{7(x-4)}{6}\)
Step-by-step explanation:
Basically you have to simplify the (x² - 16). Since it is the difference of 2 squares, it's simplified as (x + 4)(x - 4). Now that everything is simplified, you can start doing the multiplication.
\(\frac{(x+4)(x-4)}{6x} *\frac{7x}{(x+4)}\), You can cancel out the (x+4)'s
\(\frac{(x-4)}{6x} *{7x}\), There is a common factor between 7x and 6x. The common factor is x. So cancel out both "x".
You end up with this, \(\frac{7(x-4)}{6}\)
