Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²

x=13
y=13√2
Step-by-step explanation:
Since this is a 45,45,90 triangle. The two sides are equal this means that x will be equal to 13. Then, a side times the √2 is equal to the hypotenuse or y. this means that y will be equal to 13√2.

A straight line is 180° , so if you subtract 60 from 180 you get 120, and you divide 120 by 6 so the answer is 20
Answer:
x= 20
Step-by-step explanation:
Both angles form a linear pair = 180 o
6x+60 = 180
6x = 120
x = 20
6x20 +60 = 180
120 +60 = 180

Answers
Answer:
x ≠ 4/5, x ≠ 9/4
You can also write it as "all real numbers except 4/5 and 9/4."
Step-by-step explanation:
The denominator of a fraction cannot equal 0. We can write this relation to find what x does NOT equal:
(5x - 4)(4x - 9) ≠ 0
We can use the zero-product property to get two separate equations:
5x - 4 ≠ 0
5x ≠ 4
x ≠ 4/5
4x - 9 ≠ 0
4x ≠ 9
x ≠ 9/4

Answer:
h(x) = 1/2 |x - 1| - 2h(x) = - (x + 2)² + 3Step-by-step explanation:
See attachedYou need to recognize the parent function by looking at the graph. Then you need to find out how different is the graph from the parent function and finally work out the equation of the graph considering the transformations.
4)
The parent function is the absolute value function:
h(x) = |x|Its vertex is at the origin. We see the vertex has shifted and also the slope has changed.
We can find the slope easily, the ratio of rise to run is 1/2
The function becomes:
h(x) = 1/2 |x|Now considering the translation. We see the vertex has coordinate of (1, -2)
It means the graph has shifted 1 unit right and 2 units down.
The shift right is shown as:
h(x) = 1/2 |x - 1|and adding the shift down:
h(x) = 1/2|x - 1| - 2This is our final equation.
5)
Parabola is the graph of the quadratic function.
The vertex form of the function is:
h(x) = a(x - h)² + k, where (h, k) is the vertexNow, we see it is opening down and the vertex is at (-2, 3):
h(x) = a(x - (-2))² + 3 = a(x + 2)² + 3To find the value of a we can use a point on the graph. Let's use point (0, -1):
-1 = a(0 + 2)² + 3-1 = 4a + 34a = -4a = -1The function is:
h(x) = - (x + 2)² + 3what is the axis of symmetry for 3x^2 + 2x -1

A triangle has 3 interior angles and the sum of its interior angles is 180°.
If one of the three interior angles measures 80° and the two remaining angles has the same measure, what is the measure of the 3rd interior angle?
Answers
Answer:
The 3 rd interior angle would have the measure of 50°as the question says that the remaining two interior angles have the congruent magnitude thats why if one of the interior angle is 80° then the remaining angles would be 100° So as the remaining two angles measure the same we can say that the third angle measures 100°/2 = 50°
For proof :
If the remaining two angles be x then the equation forms
x + x + 80° = 180°
=> 2x = (180 - 80)°
=> x = (100/2)°
=> x = 50°
Therefore the value of x = 50°
