Enter the values needed to find the length CB

Mathematics
1 answer:
Tju [1.3M]3 years ago
7 0

Answer:

6b

Step-by-step explanation:

We know that the distance formula is \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}. We already have the x values, which are 5a and -a, subtracting -a from 5a gets us 6a.

Same concept for the y values, let's subtract the first y value from the second.

The second y value is b, while the first is -5b

b - (-5b) = b + 5b = 6b

Hope this helped!

The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and
Travka [436]

Answer:

3.2 feet


Step-by-step explanation:

The equation  f(x)=-0.3x^{2}+2x  shows the height of water [f(x)] and horizontal distance [x].

<em>Given the </em><em>horizontal distance is 4 feet</em><em>, they want to know the height.</em>


<em>Simply put 4 in x of the equation and solve for f(x). So,</em>

<em>f(x)=-0.3(4)^{2}+2(4)\\f(x)=3.2</em>

So, the height of the water was 3.2 feet above the ground.

4. Can two lines be parallel and perpendicular? Explain.
lidiya [134]

Answer: No

Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.

However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.

So no, two lines can't be both parallel and perpendicular.

Y = x^2 + 10x - 171
y = (x - 9)(x + 19)

x - 9= 0 x + 19 = 0
x = 9 x = -19

Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
