Answer:
Below
Step-by-step explanation:
To find the answers for the table, you must plug in each x value into the equation and get your y value:
x = -1
(-1^2)-(4*-1)-1
=
1+4-1
=
4
When x = -1, y = 4
x=0
(0^2)-(-4*0)-1
=
-1
When x = 0, y = -1
x = 1
(1^2)-(4-1)-1
=
1-4-1
=
-4
When x = 1, y = -4
x = 2
(2^2)-(4*2)-1
=
4-8-1
=
-5
When x = 2, y = -5
x = 3
(3^2)-(4*3)-1
=
9-12-1
=
-4
When x = 3, y = -4

the sum of the three numbers is 94. The second number is 2 times the third. The first number is 6 more than the third. what are the numbers?
Answer:
28, 44, 22
Step-by-step explanation:
a+b+c = 94
2×c = b
a = c+6
=>
c+6 + 2×c + c = 94
4×c + 6 = 94
4×c = 88
c = 22
=>
b = 2×22 = 44
a = 22 + 6 = 28
1. Find the median, mode, and mean for, {1, 4, 8, 3, 4, 5, 2, 2, 2, 5}
Answer:
Mean: 3.6
Median: 3.5
Mode: 2
Step-by-step explanation:
Mean: The sum of all numbers divided by the amount of numbers.
Median: The number in the middle.
Mode: the number that is frequently used.
------------------------------------------------------------------------------------------------------
Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6
Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5
Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.

What is a perpendicular bisector notation?
Answer:
In a pyramid, line segment AD is the perpendicular bisector of triangle ABC on line segment BC. If AB = 20 feet and BD= 7 feet, find the length of side AC.
Step-by-step explanation:
Solution
It is given that AD is the perpendicular bisector on the line segment BC.
So, By Perpendicular Bisector Theorem, any point on line segment AD is at an equal distance from points B and C. It implies, AB = AC
AC = 20 feet.
Which of the following is not equivalent to this expression?
2m + 10m +14+3
A. m +12m +8+9

C. 6m + 6m - 1 + 18
D. 15m +15 - 3m +2
Answer:
A
Step-by-step explanation:
the given equation can be simplified to 12m+17
so if we simply the other options we see that A = 13m+17
find the surface area of each figure. round to the hundredths place
Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:
[tex]A=\pi rl+\pi r^2[/tex]
Where, r is the radius of the cone and l is the slant height of the cone.
Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get
[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]
[tex]A=384.336+162.7776[/tex]
[tex]A=547.1136[/tex]
[tex]A\approx 547.11[/tex]
Therefore, the surface area of the given cone is 547.11 square m.

every parallelogram is a square?
every rectangle with four congruent sides is a square?
every rectangle is a quadrilateral?
every quadrilateral is a rectangle?
Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.
The quotient of a number and - 2/3 is -9/10
What is the number?
1 7/20
3/5
29/30
20/27
Answer:
n = 3/5
Step-by-step explanation:
Represent this quotient as:
n
---------
-2/3
and set it equal to -9/10:
n -9
--------- = -------
-2/3 10
Cross multiplication yields:
10n = 6, so that n = 6/10 or n = 3/5

The volume of a cylinder is 196in.3 and the height of the cylinder is 1 in. What is the radius of the cylinder?
Answer:
r ≈ 7.9 inches
Step-by-step explanation:
V(cylinder) = πr²h
196 = πr²(1)
196/π = r²
62.4 = r²
√62.4 = r
r ≈ 7.9
What’s the distance between the points that’s given on the graph?
The distance between two points:
[tex] \large \boxed{ \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } }[/tex]
From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:
[tex] \large{d = \sqrt{ {( - 3 - 5)}^{2} + {(1 + 4)}^{2} } } \\ \large{d = \sqrt{ { (- 8)}^{2} + {5}^{2} } } \\ \large{d = \sqrt{64 + 25} \longrightarrow \sqrt{89} } [/tex]
Hence the distance between two points is √89.
Answer
√89Which of the following values of y will result in a true statement when substituted into the given equation?
y + 4.2 = 3.4
A. y = -0.8
B. y = 2.2
C. y = 4.3
D. y = 5.2
Answer:
A. -0.8
Step-by-step explanation:
non of the other answers will work because they are positive.
Answer:
A, y = -0.8
Step-by-step explanation:
To solve this, you have leave the y alone.
Subtract 4.2 from both sides.
y + 4.2 - 4.2 = 3.4 - 4.2
y = 3.4 - 4.2
y = -0.8
What is the equation of the asymptote for the exponential function shown on the graph?
Answer:
B) y=0
Step-by-step explanation:
The exponential function shown has a horizontal asymptote at the line y=0, which means that y will approach 0 as the value of x decreases. Therefore, B is correct.
Line l has a _____ slope.
negative
0
positive
undefined
Answer:
positive
Step-by-step explanation:
negative slopes go from right to left; this line goes from left to right
0; the line isn't completely horizontal

Find the arithmetic means for the given sequence:
4, __, __, __, __, 19
Answer:
a= 4. b=19. n=4. d= b-a/n+1= (19-4)/(4+1)= 15/5=3. Hence, d=3.
Step-by-step explanation:
Do you also want an explanation?
Answer:
7 10 13 16
Step-by-step explanation:
a1 = 4
a6 = 19
n = 6
d = ?
a6 = a1 + (n - 1)d
19 = 4 + (6 - 1)*d
19 - 4 = 5*d
15 = 5d
d = 15/5
d = 3
So the sequence is
4,7,10,13,16,19

pls answer asap 7 - 3 r = r - 4 ( 2 + r)
Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
What is the solution for the equation?
h(x)=x^3 -4x g(x)=x+2 find (h/g) (x)
Answer:
(h/g)(x) = x² - 2x
Step-by-step explanation:
h(x) = x³ - 4x
g(x) = x + 2
(h/g)(x) = h(x)/g(x) = (x³ - 4x) / (x + 2) = x² - 2x
