Answer:
its B I think. because it should equal 90°
<span>Multiplying with 6 is a mathematical process similar to multiplying with 3, in that setting up the greatest common factors between the two is easy due to the fact that 6 is a multiple of 3. As 6 is simply 3 doubled, any multiple of 6 will be the relative multiplation for 3 doubled. </span>
Answer:
10
Step-by-step explanation:
IQR= Q3-Q1
Q3=50
Q1=40
50-40=10
Median=43
Answer:
Option C is correct.
Step-by-step explanation:
y = x^2+4x+5
We need to find the vertex of the above equation.
The above equation represents the parabola.
The slope of parabola can be found by taking derivative of the given equation
dy/dx = 2x+4
The slope of the parabola at the vertex is zero SO,
2x+4 = 0
2x = -4
x = -4/2
x = -2
Putting value of x =-2 to find the value of y
y = x^2+4x+5
y =(-2)^2+4(-2)+5
y = 4-8+5
y =9-8
y = 1
So, the vertex is (-2,1)
Option C is correct.
Answer:
Step-by-step explanation:
With this question, we just have to group the terms, so in this case, we can remove the common term (x - 4), and then group the rest of them
If we do that we get:
(x - 4) (2x + 7)
Hope this helps,
