Answer:
50.24
Step-by-step explanation:
Area of a circle= πr^2
Where we will take radius as 4cm and pi as 3.14 approx
= 3.14 x 4 x 4
= 3.14 x 16
= 50.24
So the area is 50.24 cm^2
Answer:
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
Step-by-step explanation:
Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.
Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).
<h3>Application</h3>
We observe that f(x) has been transformed by ...
- multiplying by -1 to get -f(x)
- replacing x with (x -2) to get -f(x -2)
- adding -3 to the function value to get -f(x -2) -3
The effect of these transformations is (correspondingly) ...
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
__
The attached graph shows a function f(x) (red) and the transformed function (blue).
Answer: x = -1
Step-by-step explanation:
The problem is asking you the sum (+) of 3 times of a unknown number (let the unknown number be x) and 7, as in 3x + 7
According to the problem this expression is equal to 4,
3x + 7 = 4
1. Subtract 7 from both sides
3x = -3
2. Divide 3 on both sides
x = -1
Your final answer would be negative 1
Answer:
81
Step-by-step explanation:
u multiply 9 x 9 not 9x2
First, let’s make these two fractions complement each other by giving them the same denominator.
11/4 = 22/8
22/8-3/8
This equals 19/8. Because this cannot be simplified any further, the answer is 19/8 k.
