Answer:

The function is given to be :

y=-0.5\sqrt{x-3}+2

Since, square root function cannot have negative value for any real value of square root

⇒ x - 3 > 0

⇒ x > 3

At x = 3 , y = 2

So, graph of the given function will have least value of x = 3 and highest value of x = ∞

Least value of y = -∞ and highest value of y = 2

Also, at y = 0, x-intercept , x = 19

Hence, the required graph of the given function is given below :

A <br> is a number formed by multiplying ten by a number.
PIT_PIT [208]

I'm not really sure what the question is here, because you just gave a statement... but if you are trying to get an expression from words, here is what it would be:

A = 10N

I'm also not sure if "a number" is equal to the same as "a number" at the end, but I'm guessing not. If it is though, and you're trying to find the value of A, the answer would be:

A = 10

Martha has driven about 2/3 the distance she needs to go to reach her aunt's house. Her brother Jackson is making the same trip
Harman [31]
The answer is A. Martha has a shorter distance left to get to the aunt’s house than Jackson since 2/3 is .667 or 67%. Therefore this statement is false

The line passing through (-2,5) and (2,p) has a gradient of -1/2. <br><br> Fnd the value of p
makkiz [27]

Given:

The line passing through (-2,5) and (2,p) has a gradient of -\dfrac{1}{2}.

To find:

The value of p.

Solution:

If a line passes through two points, then the slope of the line is:

m=\dfrac{y_2-y_1}{x_2-x_1}

The line passing through (-2,5) and (2,p). So, the slope of the line is:

m=\dfrac{p-5}{2-(-2)}

m=\dfrac{p-5}{2+2}

m=\dfrac{p-5}{4}

It is given that the gradient or slope of the line is -\dfrac{1}{2}.

\dfrac{p-5}{4}=-\dfrac{1}{2}

On cross multiplication, we get

2(p-5)=-4(1)

2p-10=-4

2p=-4+10

2p=6

Divide both sides by 2.

p=3

Therefore, the value of p is 3.
