Write an equation in point-slope form for the line through the given point with the given slope.(3,-4);m=-1/4
Answer:
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]
Step-by-step explanation:
The point slope form of a line is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
Here m is the slope and (x1,y1) are the coordinates of the point through which the line passes.
Given
m = -1/4 and
(x1,y1) = (3,-4)
Putting the values in the point-slope form of line
[tex]y-(-4) = -\frac{1}{4}(x-3)\\y+4 = -\frac{1}{4}(x-3)[/tex]
Hence,
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]
14. Which set of side lengths can be used to prove the statement below is false?
"In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides."
a) 4 cm, 5 cm, 7 cm
b) 5 cm. 12 cm 13 cm
c) 3 cm, 4 cm, 5 cm
d) 9 cm, 12 cm, 15 cm
Answer:
a) 4 cm, 5 cm, 7 cm
Step-by-step explanation:
The statement "In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides." is only true for triangle rectangles.
To find a counter example, we can try with the options and see which one works as a counterexample:
a) 4 cm, 5 cm, 7 cm
The longest side is 7cm, then the statement says that:
4^2 + 5^2 = 7^2
16 + 25 = 51
while 7^2 = 49
Then for this particular set of sides, the statement is false.
So we already found the counter example, because:
4^2 + 5^2 ≠ 7^2
The only set of side lengths that proves that the statement "In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides." is false is;
Option A; 4 cm, 5 cm, 7 cm
To answer this question, let us look at each option;
Option A; 4 cm, 5 cm, 7 cm
Thus; 4² + 5² = 51 and 7² = 49
Since the sum of the square of the two shorter sides is not equal to the square of the longest side, then this proves the statement is false.
Option B; 5 cm. 12 cm 13 cm
Thus; 5² + 12² = 169 and 13² = 169
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.
Option C; 3 cm, 4 cm, 5 cm
Thus; 3² + 4² = 25 and 5² = 25
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.
Option D; 9 cm, 12 cm, 15 cm
Thus; 9² + 12² = 225 and 15² = 225
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.

Which exponential function is represented by the graph?
O f(x) = 2( 1/2 )x
O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!
Answer:
f(x) = [tex]\frac{1}{2}[/tex] [tex](2)^{x}[/tex]
Step-by-step explanation:
Using the standard form of the exponential function
y = a [tex]b^{x}[/tex]
To find a and b , substitute ordered pairs from the graph
Using (0, 0.5 ), then
0.5 = a[tex]b^{0}[/tex] [
a = 0.5 , so
y = [tex]\frac{1}{2}[/tex] [tex]b^{x}[/tex]
Using (1, 1) , then
1 = [tex]\frac{1}{2}[/tex][tex]b^{1}[/tex] , thus
b = 2
f(x) = [tex]\frac{1}{2}[/tex][tex](2)^{x}[/tex] ← exponential function representing graph

How do you write this in index form?
The general form is nthroot{a} in index form looks like this: a^(1/n).
Let's rationalize the denominator first.
Doing so, we get (1/2)sqrt{2}.
In index form, the sqrt{2} = 2^(1/2).
We now have (1/2)[2^(1/2)].

slopes in order (3,13) (27,13) ; (1,4) (7,10) ; (-3,1) (2,11) ; (0,10) (5,11)
Answer:
Step-by-step explanation:
Given any two points, you can find the slope of the line between them using the equation
[tex]m = \frac{y_2-y_1}{x_2-x_2}[/tex]
#1:
(3, 13), (27, 13): [tex]m = \frac{13-13}{27-3} = \frac{0}{24} = 0\\[/tex]
(1, 4), (7, 10): [tex]m = \frac{10-4}{7-1} = \frac{6}{6} = 1\\[/tex]
(-3, 1), (2, 11): [tex]m = \frac{11-1}{2-(-3)} = \frac{10}{5} = 2[/tex]
(0, 10), (5, 11): [tex]m = \frac{11-10}{5-0} = \frac{1}{5} = 0.2[/tex]

The box will go from 10 to 12. A line dividing the box will be at 12. The left whisker will go from 4 to 15. The right whisker will go from 12 to 20.
Given:
A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20.
To find:
The correct statement for the box plot.
Solution:
Lower quartile is 10 and upper quartile is 15, so the box will go from 10 to 15.
Median of the data set is 12, so a line dividing the box will be at 12.
Minimum value is 4 and lower quartile is 10, so the left whisker will go from 4 to 10.
Upper quartile is 15 and maximum value is 20, so the right whisker will go from 15 to 20.
Therefore, the correct option is B.

The formula for the volume of a tetrahedron is given as v=sh. Rewrite the
equation so that the height is a function of the area of base and the volume (solve for
the height), then find the height when the area of base is 8 and the volume is 48.
Answer:
h = 6 units
Step-by-step explanation:
The formula for the volume of a tetrahedron is given as :
V = sh
Where
s is area of base and h is height
Put s = 8 and V = 48 to find h as follows :
[tex]h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6[/tex]
So, the height of the tetrahedron is 6 units.
