Rewrite the sum of 30 and 42 by factoring out of the greatest common factor
Answer:
12
Step-by-step explanation:
Factors of 30: 1,2,3,5,(6),10,15,30
Factors of 42: 1,2,3,(6),7,14,21,42
30 divided by 6, 42 divided by 6
(5) + (7)= 12

we want to find the zeros of this polynomial:
p(x)=(x-1)(x+3)(2x+1)
plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
Answer:
(- 3, 0), (- 1/2, 0), (1, 0)
Step-by-step explanation:
p(x)=(x-1)(x+3)(2x+1)
Plug p(x) = 0
Therefore,
(x-1)(x+3)(2x+1) = 0
x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0
x = 1 or x = - 3 or x = - 1/2
Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial

The first 4 terms of a geometric sequence are 2, 6, 18, 54. Part A: Find the common ratio. Remember the common ratio is the number that is multiplied to each value to get the next number. Part B: Find the next 3 values in the geometric sequence Come up with your own geometric sequence and identify the common ratio.
Answer:
Common ratio is 3
The three terms are 162, 486, 1458
Step-by-step explanation:
Given: The first 4 terms of a sequence are [tex]2,6,18,54[/tex]
To find:
A. the common ratio
B. the next 3 values in the geometric sequence
Solution:
Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.
A.
[tex]\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3[/tex]
So, the common ratio is [tex]3[/tex]
B.
The next three values are as follows:
[tex]54(3)=162\\162(3)=486\\486(3)=1458[/tex]

Suzanne owns stock worth $2,400. She owes $5,200 in student loans, and $2,500 on a credit car. She owes $1,800 on a car that is worth $8,000. What is Suzanne's net worth in dollars?
Answer:
15,100
Step-by-step explanation:
because 5,200+2,500+8,000+1,800=17,500 which is how much she owes and what she has is 2,400 so 17,500- 2,400= 15,100 so her net worth is 15,100

How does the graph of an inverse function compare to the original function?
A. The inverse function is the original function reflected over the x-axis
B. The inverse function is the original function reflected over y=x
C. The inverse function is the original function reflected over y=-x
D. The inverse function is the original function reflected over the y-axis
The inverse function is the original function reflected over y=x option (B) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a statement:
The graph of an inverse function compare to the original function:
As we know, every function with domain real numbers can be plotted on graph paper or a coordinate plane.
Let f(x) = ax + b
or
y =ax + b
a and b are the real numbers
To find the inverse of a function interchange the value of x and y
f⁻¹ = x = ay + b
If we plot the above two functions we will see that f(x) is the mirror image of f⁻¹ over the line y = x.
Thus, the inverse function is the original function reflected over y=x option (B) is correct.

Answer:
to find how many sales Ross made in a day divide 27 by 3 and to find Mona's divide 49 by 7 since there is 7 days in a week
Step-by-step explanation:
27/3 = 9 so Ross made 9 sales in a day
49/7 = 7 so Mona made 7 sales in a day
9>7
therefore Ross made more sales

How do you determine if triangles or any polygons are similar?
For example, all equilateral triangles are similar and all squares are similar. If two polygons are similar, we know the lengths of corresponding sides are proportional. In similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale factor.

Which expressions are equivalent to 2 ( a + 3 b ) 2(a+3b)? Mark all that apply. A 2a+6b2a+6b B a+(a+6b)a+(a+6b) C 2b+3a2b+3a D a+3ba+3b E 2a+(5+1)b2a+(5+1)b F a2+b5a 2 +b 5 G
Answer:
A. 2a+6b
B. a+(a+6b)
D. a + 3b
E. 2a+(5+1)b
Step-by-step explanation:
Given:
2(a + 3b)
Open parenthesis
= (2a + 6b)
A 2a+6b
B. a+(a+6b)
= a + a + 6b
= 2a + 6b
C 2b+3a
Not equivalent
D. a + 3b
2a + 6b
Divide through by 2
= a + 3b
E. 2a+(5+1)b
= 2a + (6)b
= 2a + 6b
F. a2+b5
Not equivalent

Answer:
[tex]x = 9[/tex]
[tex]y = 17[/tex]
Step-by-step explanation:
This is a cyclic quadralterial so opposite angles are supplementary.
The x variables add up to 180 so
[tex]11x + 8 + 8x + 1 = 180[/tex]
[tex]19x + 9 = 180[/tex]
[tex]19x = 171[/tex]
[tex]x = 9[/tex]
The y variables add up to 180.
[tex]6y - 4 + 5y - 3 = 180[/tex]
[tex]11y - 7 = 180[/tex]
[tex]11y = 187[/tex]
[tex]y = 17[/tex]

Write an explicit formula for the geometric sequence below and use it to find the 9th term.
256, 64, 16, 4, . . .
Answer:
The explicit formula is;
Tn = 256(1/4)^(n-1)
The 9th term is;
256/65536
Step-by-step explanation:
Mathematically, we have the nth term of a geometric sequence as;
Tn = ar^(n-1)
a is the first term = 256
r is the common ratio = 64/256 = 16/64 = 4/16 = 1/4
So, for the 9th term, we have
T9 = 256(1/4)^(9-1) = 256/65536
The explicit formula is;
Tn = 256(1/4)^(n-1)

James has 10 baseballs that each
have 5 signatures on them. James
says he has 45 signatures. Is James
correct? Explain.
Answer:No he is not correct.
Step-by-step explanation:
Since each baseball has signatures on them and he has 10 of them we have to multiply 10 by 5 and we get 50 not 45.So he had 50 signatures in total therefore is not correct.

There is a cylinder with a height of 8 units and a volume of 72 cubic units. What is the radius of the cylinder?
Answer:
Radius of the cylinder = 1.69 units
Step-by-step explanation:
Volume of a cylinder is given by the expression,
Volume = Area of the circular base × Height of the cylinder
Area of the circular base = πr²
Here, r = Radius of the circular base
Volume of the cylinder = πr²h
By substituting the values given in the question,
72 = π(r)²8
r² = [tex]\frac{9}{\pi }[/tex]
r² = 2.865
r = 1.692
r = 1.69 units
