What is the slope of the line?
y
slope = 13
slope = -3
slope =3
Answer:
slope = 3
Step-by-step explanation:
Take a look at the grid, when the x = 0, y = -2, so it means you have a function with form y = a•x - 2
Now, look at the grid lime when x = 2, at this point, y = 4. If the function doesn't had -2, y in x = 2 would be 4 + 2 = 6
Which number you multiply 2 to have 6? Number 3, so this is the slope, and the function is y = 3x -2
Answer:
3
Step-by-step explanation:
Start at the y-intercept
Slope is rise (up/down) over run (move to the right/left)
First you rise 3
And you run 1
3/1 is 3 thus 3

Answer:
23/3 or 7 2/3 units ^3
Step-by-step explanation:
The formula for volume is
V = Bh where B is the area of the base and h is the height
V = 23/4 * 4/3
Rewriting
V = 23/3 *4/4
V = 23/3 units ^3
or if they want a mixed number
V = 7 2/3 units ^3

Answer:
27/10
Step-by-step explanation:
You want to get a common denominator in order to add them together.
First:
Convert the whole numbers to fractions, 4 = 8/2
4 1/2 = 9/2
And 1 = 10/10
1 8/10 = 18/10
Then find the common denominator:
The least common multiple of 2 and 10 is 10. So:
convert 9/2 to a denominator of 10 : 9*5 / 2*5 = 45/10
Subtract:
45/10 - 18/10 = 27/10
Answer:
27/10
Step-by-step explanation:
1. Change the mixed fractions to improper fractions
9/2 -9/5
2. Find the LCD, 10
3. multiply to get the denominator to 10
45/10 - 18/10
4. Deal with the numerators 45-18=27
5. 27/10
10 fewer than the difference of 8 and w! Please helpppppppp!!!!!!!! get 5 stars and brainly and heart!!!!!!!
Answer:
(8-w) -10
Step-by-step explanation:
fewer than comes after
difference of 8 and 2
(8-w)
10 fewer than
(8-w) -10
Answer:
(8 - w) - 10
Step-by-step explanation:
10 fewer than the difference of 8 and w.
-10
fewer means that we are taking away something, so it is minus.
8 and w (difference)
and is a word that adds something, but we have to pay attention to the difference. that means -.
8 - w
Put parenthesis around it so we know it is 8 and w that seperates from the (10 fewer).
(8 - w)
add - 10 at the end
(8 - w) - 10

Which of the following statements is true?
A. A data set will always have exactly one mode
B. A data set can have multiple modes
C. A data set will always have at least one mode
D. A data set will never have a mode
Answer:
B
Step-by-step explanation:
Let's go over each option with the process of elimination!
A. A data set will always have exactly one mode.
Contradiction: 2, 2, 3, 3, 4, 5, 6
in this data set, both 2 and 3 are modes, so it is incorrect.
B. A data set can have multiple means.
True, example as A.
C. A data set will have at least one mode.
Contradiction: 2, 3, 4, 5, 6
There are no modes in here.
D. A data set will never have a mode.
Contradiction: 2, 2, 3, 4, 5
The mode is 2.
The only true statement is answer B.
I hope this helped! :D
Answer:
b
Step-by-step explanation:
if a data set had 1,1,3,4,4 how would you have 2 modes, 1,4. If you had 1,1,2,2,3,3 you would have 1,2,3 as your modes
a is wrong, c is wrong, d is wrong
a:my example has more that one
c:i have no explanation

Tell which set or sets the number below belongs to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers.
26
Select all that apply.
O A. rational numbers
B. natural numbers
I c. irrational numbers
D. integers
E. whole numbers
OF. real numbers
Answer:
A
B
D
E
F
Step-by-step explanation:
26 can be also written as 26/1 or 52/2 or ...
so, it is part of the rational numbers.
it is clearly a natural number (1, 2, 3, 4, ...).
it is also an integer (... , -2, -1, 0, 1, 2, 3, ...).
it is a whole number (0, 1, 2, 3, 4, ...)
and it is a real number, as it can be written as 26.0. real numbers are the superset of all these mentioned sets of numbers.
but it is NOT an irrational number, as they have infinite digits after the decimal point without any repeating pattern.
in other words, any number that is a member of the rational numbers cannot be an irrational number. and vice versa.

if tanA=2ab/a square-b square.find the value of cosA and sin A
Answer:
[tex]\displaystyle \displaystyle \cos A = \frac{a^2-b^2}{a^2 + b^2}\text{ and } \sin A = \frac{2ab}{a^2 + b^2}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \tan A = \frac{2ab}{a^2 - b^2}[/tex]
And we want to find the value of cos(A) and sin(A).
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the opposite side measures 2ab, and the adjacent side measures a² - b².
Using the Pythagorean Theorem, solve for the hypotenuse:
[tex]\displaystyle \begin{aligned} c^2 &= a^2 + b^2 \\ \\ c&= \sqrt{(2ab)^2 + (a^2-b^2)} \\ \\ &= \sqrt{(4a^2b^2)+(a^4-2a^2b^2+b^4)} \\ \\ &= \sqrt{a^4 + 2a^2b^2 + b^4 } \\ \\ &= \sqrt{(a^2 +b^2)^2} \\ \\ &= a^2 + b^2\end{aligned}[/tex]
Thus, our hypotenuse is given by a² + b².
Cosine is the ratio between the adjacent side and the hypotenuse. Thus:
[tex]\displaystyle \cos A = \frac{a^2-b^2}{a^2 + b^2}[/tex]
And sine is the ratio between the opposite side and the hypotenuse. Thus:
[tex]\displaystyle \sin A = \frac{2ab}{a^2 + b^2}[/tex]
In conclusion:
[tex]\displaystyle \displaystyle \cos A = \frac{a^2-b^2}{a^2 + b^2}\text{ and } \sin A = \frac{2ab}{a^2 + b^2}[/tex]
Answer:
Step-by-step explanation:
[tex]sec^2A-tan^2A=1\\sec^2A=1+tan^2A=1+\frac{4a^2b^2}{(a^2-b^2)^2} =\frac{(a^2-b^2)^2+4a^2b^2}{(a^2-b^2)^2} =\frac{(a^2+b^2)^2}{(a^2-b^2)^2} \\cos^2A=\frac{(a^2-b^2)^2}{(a^2+b^2)^2} \\cos A=\frac{a^2-b^2}{a^2+b^2} \\sin A=\sqrt{1-cos^2A} =\sqrt{1-(\frac{a^2-b^2}{a^2+b^2} )^2} =\sqrt{\frac{(a^2+b^2)^2-(a^2-b^2)^2}{(a^2+b^2)^2} } =\sqrt{\frac{4a^2b^2}{(a^2+b^2)^2} }=\frac{2ab}{a^2+b^2}[/tex]

perimeter is the sides added together
Answer:
44 units
Step-by-step explanation:
The tangents from an external point to a circle are congruent, then
perimeter = (9 + 9) + (8 + 8) + (13 - 8 ) + (13 - 8)
= 18 + 16 + (5 + 5)
= 18 + 16 + 10
= 44 units
If g(x) = (x + 2)/3, find g(-8).
Answer:
-2
Step-by-step explanation:
Substitute -8 in place of x and you get (-8+2)/3 or -6/3 which is -2
Answer:
g(- 8) = - 2
Step-by-step explanation:
To find g(- 8) substitute x = - 8 into g(x) , that is
g(- 8) = [tex]\frac{-8+2}{3}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2

Which of the quadratic functions has the narrowest graph?
A. y= 1/8x2
B. y= 1/6x2
C. y= -x2
D. y= 2x2
Answer:
D. y= 2x2
Step-by-step explanation:
y = ax^2
If the absolute value of a is <1 the graph is wider than when a = 1
If the absolute value of a is >1 the graph is narrow than when a = 1
The only function that fits that description is
y = 2x^2
B <<< answer.
Given: We are given equation of parabola ans to choose narrowest graph.
Parabola form narrowest and widest.
Larger value of a most narrowest graph.
Smaller value of a most widest graph.
Now, we will see the coefficient of x²
Now, we arrange the value of a in descending order.
2 is largest value of these.
Hence, The narrowest graph is

<1 and <2 are vertical angles. If m<1 = (5x+12) and m<2 = (23x + 17) find m<2
Answer:
m∠2 = 10 11/18°
Step-by-step explanation:
Vertical angles are equal to one another.
[tex]5x+12=23x+17\\\\12=18x+17\\\\-5=18x\\\\-\frac{5}{18}=x[/tex]
Now substitute the value for the variable to find m∠2.
[tex]23(-\frac{5}{18})+17\\\\-\frac{115}{18}+17\\\\\frac{191}{18}=10\frac{11}{18}[/tex]
