Answer:
x=70
Step-by-step explanation:
Since they are supplementary angles (180°)
45° + (2x-5)° = 180°
(2x-5)° = 180° - 45°
(2x-5)° = 135°
2x° = 135° + 5°
2x° = 140°
x° = 140/2°
x° = 70°
Since they are supplementary angles (180°)
45° + (2x-5)° = 180°
(2x-5)° = 180° - 45°
(2x-5)° = 135°
2x° = 135° - 5°
2x° = 130°
x° = 130/2°
x° = 65°
Answer:
Step-by-step explanation:
Since ABC is a right triangle, at any moment it holds that
Moreover, the area A of the triangle is given by
and we know that the rate of change of the length (AC) is
constant decreasing 2, which may be written using the Leibniz
notation as
.
Using the chain rule and the product rule for derivation, the two
first equations tell us
that
and
Moreover, using the first of the last two equations we get
Now, when (AC)=3, we have that
and
.
Hence, at this moment the rate of change of the area of the triangle is
b. translate left 12 units, stretch horizontally by a factor of 4, and reflect over the x-axis.
need steps don't understand how to do!
For a, the transformed function is 5*|x+9| - 23 after translating 9 units to the left, stretching vertically by a factor of 5, and translating down 23 units. For b, the transformed function is -|(x+12)/4|, after translating 12 units to the left, stretching horizontally by a factor of 4, and reflecting over the x-axis.
The given function is f(x) = |x|. To write the equation for each transformation, you need to understand how they influence the function.
a. To translate the function left 9 units, the value 9 needs to be added inside the absolute value brackets creating f(x) = |x+9|. To stretch it vertically by a factor of 5, we multiply the entire function by 5 - 5 * f(x) = 5*|x+9|. Lastly, to translate down 23 units, we subtract 23 from the entire function, leading us to 5*|x+9| - 23.
b. To translate left 12 units, we change the function to |x+12|. To stretch horizontally by a factor of 4, divide the x inside the absolute value by 4, getting |(x+12)/4|. To reflect over the x-axis, we multiply the entire function by -1, leading to -|(x+12)/4|.
Answer:
the answer would be 270
Step-by-step explanation:
i can explain later:
since x = 5, you plug it in f = 4x +7, and you get f = 27 and since 1/2x is in the denominator, it will flip over and become 2x. 2x is 10, so you multiply f by g and get 270 which is if f/g(5) is the question.

Answer:
The coordinates of O is (d,c) .
Option (a) is correct .
Step-by-step explanation:
As given
In the coordinate plane, three vertices of rectangle MNOP are M(0, 0), N(0, c), and P(d, 0).
As MNOP is a rectangle .
Thus opposite sides of the rectangles are equal .
Formula
NM = c units
MP = d units
Thus the coordinate of the O (d,c) .
(This is because opposit sides of the rectangle are equal thus distance of point O from point P must be d and distance of point O from point N must be c .)
Therefore the coordinates of O is (d,c) .
Option (a) is correct .
