Answer:
4/3
Step-by-step explanation:
Sounds as though this problem presented several rates of change, but you have shared only one: 3y - 4x = 3. If we take x to be the independent variable, then 3y = 4x + 3, and y = (4/3)x + 1. The rate of change of this function (the rate of change of y with respect to x) is therefore 4/3.

A. 942.48 cm²
B. 376.99 cm²
C. 565.49 cm²
D. 226.19 cm²
Answer:
D
Step-by-step explanation:
To first tackle this question, use similarity ratio, where the missing diameter is d. 10/15 = d/9 which can be simplified into d = 6. Then use the surface formula
2πrh + 2πr². Then, since the radius is 0.5d, the radius or r is 3. Then, plus in values and simplify to get 226.19cm².

Choose the slope and y-intercept that corresponds with the graph.
Answer:
slope 3, y intercept 4
Step-by-step explanation:
The y intercept is where it crosses the y axis
It crosses at y=4
The slope is positive since it goes from bottom left to top right
The slope is up 3 over 1 so it is 3/1 = 3

Answer:
1.) x^2 + 3x
2.) 3x^2 - 3x
3.) 278
Step-by-step explanation:
You are given the following functions:
f(x) = x + 5
g(x) = x2 + 4x + 5
h(x) = 3x2 - 2x + 5
1.) To match the function with its value,
(f+g)(x) = f(x) + g(x)
Substitutes for the two functions
X + 5 = x^2 + 4x + 5
Collect the like terms and equate them to zero
X^2 + 4x - x + 5 - 5
X^2 + 3x
Therefore, (f+g) (x) = x^2 + 3x
2.) (f*h)(x) = f(x) × h(x)
x + 5 = 3x^2 - 2x + 5
Collect the like terms
3x^2 - 2x - x + 5 - 5
3x^2 - 3x
Therefore, (f×h)(x) = 3x^2 - 3x
3.) h[f(5)] -g[h(1)]
First find f(5)
That is, substitute x for 5 in f(x)
f(5) = 5 + 5 = 10
Also, do the same for h(1)
h(1) = 3(1)^2 - 2(1) + 5
h(1) = 3 - 2 + 5 = 6
h[f(5)] - g[h(1)]
= 3(10)^2 - 2(10) + 5 - (6)^2 + 4(6) + 5
= 300 - 20 + 5 - 36 + 24 + 5
= 334 - 56
= 278
Therefore, h[f(5)] - g[h(1)] = 278

Answer:
Similarity statement is a little mixed up.
Step-by-step explanation:
Your similarity statement is a little off. The order in the statement DOES MATTER. For example angle E corresponds with angle V or T (∠V≅∠T). These would be correct...

FEDC similar UTSVFEDC similar STUV****There are a lot but the first letter of the first polygon corresponds with the first letter of the second polygon and so on. That is the only way this statement is true. There are about a 96 different combinations for this so any one would work.
The similarity ratio is the same thing as asking "what value would make the first polygon congruent to the second"? In this case 1(x) = 4, x = 4. Therefore the ratio is 4, or 4/1 (if asked can also be written as 4:1. THE ORDER IS ALSO VERY IMPORTANT.

What is the product of two matrix?The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.
The given matrix is [tex][3]\left[\begin{array}{ccc}-7\\11\\2\end{array}\right][/tex]
Here, the product is [3×(-7) 3×11 3×2]

2
hours
B) 2:30 pm
C) 45 mph
D) 75 miles
Answer:
t=2.5 hours after the freight train leaves the station they will meet.
Step-by-step explanation:
30t = 50 (t - 1)
30t = 50t - 50
30t - 50t = -50
-20t = -50
t= -50/-20
Therefor, t=2.5 hours after the freight train leaves the station they will meet.

largest side opposite ∠ W is XV
smallest side opposite ∠ X is VW
side between them opposite ∠ V is WX

B. It forms a linear pair with one of the interior angles of the triangle.
C. It is formed by two segments that are not sides of the triangle,
D. It is complementary to one of the interior angles of the triangle.
Answer:
B. It forms a linear pair with one of the interior angles of the triangle.

The true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.
What is the exterior angle of a triangle?The exterior angle theorem asserts that the total of the opposing and non-adjacent internal angles of a triangle equals the measurement of each exterior angle.
When one side of a triangle is stretched in such a way that a non-straight angle is produced exterior of the triangle but near to an interior angle, an external angle is formed.
Therefore, we can conclude that the true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.

A special type of password consists of 3 different letters of the alphabet, and the two different numbers, where each letter and each number is used only once. How many different possible passwords are there?
Answer:
There can be 14,040,000 different passwords
Step-by-step explanation:
Number of permutations to order 3 letters and 2 numbers (total 5)
(AAANN, AANNA,AANAN,...)
= 5! / (3! 2!)
= 120 / (6*2)
= 10
For each permutation, the three distinct (English) letters can be arranged in
26!/(26-3)! = 26!/23! = 26*25*24 = 15600 ways
For each permutation, the two distinct digits can be arranged in
10!/(10-2)! = 10!/8! = 10*9 = 90 ways.
So the total number of distinct passwords is the product of all three permutations,
N = 10 * 15600 * 90 = 14,040,000
Which transformations can be used to carry ABCD onto itself? The point of
rotation is (3,2). Check all that apply.
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.
Which simplified fraction is equivalent of 5.6 3/15 14/25 5/6 14/250
Answer:
Thus, 28/5 is equivalent of 5.6
Step-by-step explanation:
Given
Number is 5.6
it is in decimal form.
The first number after decimal represent the tenth of number
The Second number after decimal represent the hundredth of number
and similarly we can define thousandth of a number.
Step to write decimal number in fractional form is (say a.bcd
write the full number without decimal
so number will be
abcd
divide the number by 1
abcd/1
now count the number of digit after decimal and put as many 0's after 1
there are three digits after decimal, we will put three digit after 1 in denominator
thus number in fraction is
abcd/1000
_________________________________________________
Given number is 5.6
hence writing it in fractional form as explained above
5.6 = 56/10
56 = 28*2
10 = 2*5
5.6 = 56/10 = 2*28/2*5 = 28/5
Thus, 28/5 is equivalent of 5.6
Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6). Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
I did this problem on a test
52.33% is the percentage of the triangle does the circle cover.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
We need to find the percentage of triangle covered by circle.
we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
Radius = =√(1.2-0)²+(1.6-0)²
=2 units
Now, area of circle is given by the formula:
Area = πr²=3.142×4=12.56 sq units
Percentage of Triangle covered:
Area of circle/Area of triangle × 100
12.56/24× 100
52.33%
Hence, 52.33% is the percentage of the triangle does the circle cover.

The table represents a function. A 2-column table with 5 rows. The first column is labeled x with entries negative 6, 7, 4, 3, negative 5. The second column is labeled f of x with entries 8, 3, negative 5, negative 2, 12. Which value is an output of the function? –6 –2 4 7
Answer:
-2 is the output of the function.
Step-by-step explanation:
We have been given the table with two columns.
First column contains the values for x : -6, 7, 4, 3, -5
Second column contains the values for f(x): 8, 3, -5, -2, 12
The first column represents the imput values x which are independent. As the second value is labelled as f(x), it means all the values which we get after inputting values of x. Hence, f(x) represent the output values.
As the options given in the question for the values are -6,-2,4,7 , only one of these values match the outputs given in the second column which represents f(x), and that value is -2
