Answer:
The area of triangle is 120 cm².
Step-by-step explanation:
First, you have to calculate the height of the triangle using Pythogorem Theorem :
Let a = base = 10 cm,
Let b = height = h cm,
Let c = hypotenuse = 26 cm,
We have found out that the height is 24 cm. Next, we have to use the area of triangle formula :
Let base = 10cm,
Let height = 24cm,
Square root of 1/8 is irrational, so is square root of 1/2, so is square root of 1/10.

The central angle O is a complete angle, so its measure is 360°. It is divided into 5 equal parts, so each of them has a measure of 360°/5=72°
Answer:
x = 12 is the excluded value
Step-by-step explanation:
An excluded value is the value/s of x that make the denominator of the rational function equal to zero as this would make the function undefined.
Equate the denominator to zero and solve for x
6x - 72 = 0 ⇒ 6x = 72 ⇒ x = 12 ← excluded value

Step-by-step explanation:
2x^2-3x-5=y
(2x-5)(x+1)=y
(2x-5)(x+1)=0
2x-5=0
2x=5
x=2.5
x+1=0
x=-1
you have an even degree (2) and a positive coefficient (2)
therefore as x---> -∞, f(x)----> +∞
also, as x----> +∞, f(x)----> +∞
also notice that this is a parabola that opens upwards so both "ends" approach positive infinity
plot the x-intercepts, find the vertex using h=-b/2a and substituting this value into the equation to find k and make a table of values to graph the parabola unless you only want a rough sketch of the graph-you know the x-intercepts and you found the vertex using h=-b/2a
