Answer:
The answer is C.
There is a horizontal line test but the question asks to use the vertical line test. Using the horizontal line test you would get that the function is not one to one but using the vertical line test you would get its one to one.
Answer:
Well just looking at the choices can lead you to the answer right away.
Well since the probability of boys and girls are equal, its 50/50. And since 125 in half well about is about 60-62 and the minimum amount of girls has to be 70. It can’t be higher then half and the choices remain to less then half not including 50%. So that eliminates all 3 choices except B.
Answer:
26.
Step-by-step explanation:
Given, BD is a median. As it divides the AC equally, that's why it will AD=CD. Given, AD= 6x+10 and CD= 2x+12
Now, AD= CD
or, 6x+10=2x+12
or, 6x-2x= 12-10
or, 4x= 2
or, x= 1/2
So the value of x is 1/2. As BD divided AC equally, both AD and CD will be equal and AD+CD= AC.
So, 6x+10+2x+12= AC
or, 8x+22= AC
or, 8 X (1/2) + 22= AC
or, 4+22 = AC
or, AC= 26.=
Answer:
LB = 12ft
Step-by-step explanation:
m< CAB = 60 because of the triangle sum theorem
We can use triangle sum theorem to find the measure of all the angles in triangle CLA.
m< CAL = 60/2 = 30, because AL is a angle bisector
The m<CLA = 60 because of the triangle sun theorem
Then we can use properties of a 30 - 60 - 90 triangle.
LA = 12
Then, we also know that m< ALC = 30 because that is what is reamining of that angle.
So, we can see that triangle ALB is a isosceles triangle.
Then LA would equal LB by the definition of a Isosceles triangle, so LB would be 12 as well.
