Answer:

The statement that is true is;

The vertices of the image are closer to the origin than those of the pre-image

Step-by-step explanation:

The dilation rule is 0.75(x,y)= (0.75x, 0.75y)

 K (-4,4)----------( 0.75*-4,0.75*4)-------K' (-3,3)

 L (2,4)-----------(0.75*2,0.75*4)---------L' (1.5,3)

M (-2,2)----------(0.75*-2,0.75*2)--------M' (-1.5,1.5)

Find the line through
Kaylis [27]

Answer:

(\frac{1}{2},\frac{-1}{2},\frac{1}{2})

Step-by-step explanation:

We have been given the intersection coordinates:

(7,1,-6) and perpendicular to the line x=-1+t ,y=-2+t and z=-1+t

From the condition of perpendicularity we know:  

(7,1,-6)(x,y,z)

\Rightarrow 7x+y-6z=0

Now, we have given x=-1+t , y=-2+t and  z= -1+t

7(-1+t)+(-2+t)-6(-1+t)=0

-7+7t-2+t+6-6t=0

\Rightarrow -3+2t=0

2t=3

t=\frac{3}{2}

Now, substituting t in the given coordinates x,y and z we get:

x=-1+\frac{3}{2}=\frac{1}{2}

y=-2+\frac{3}{2}=\frac{-1}{2}

And z=-1+\frac{3}{2}=\frac{1}{2}

the value of c guaranteed to exist by the Mean Value Theorem for V(x) = x² in the interval [0, 3] is...? a) 1 b) 2 c) 3/2 d) 1/2
lilavasa [31]

Answer:  c) \dfrac{3}{2} .

Step-by-step explanation:

Mean value theorem : If f(x) is defined and continuous on the interval [a,b] and differentiable on (a,b), then there is at least one number c in the interval (a,b) (that is a < c < b) such that

\begin{displaymath}f'(c) = \frac{f(b) - f(a)}{b-a} \cdot\end{displaymath}

Given function : f(x) = x^2

Interval : [0,3]

Then, by the mean value theorem, there is at least one number c in the interval (0,3) such that

f'(c)=\dfrac{f(3)-f(0)}{3-0}\\\\=\dfrac{3^2-0^2}{3}=\dfrac{9}{3}\\\\=3

\Rightarrow\ f'(c)=3\ \ \ ...(i)

Since f'(x)=2x

then, at x=c, f'(c)=2c\ \ \ ...(ii)

From (i) and (ii), we have

2c=3\\\\\Rightarrow\ c=\dfrac{3}{2}

Hence, the correct option is c) \dfrac{3}{2} .

An arts academy requires there to be 5 teachers for every 125 students and 4 tutors for every 88 students. How many students doe
nikitadnepr [17]

Answer:

25 students peer teacher, 22 students per tutor, 4 tutors for 81 students

Step-by-step explanation:

You need to find the unit rate,

for the teachers, to find the unit rate would be 125 divided by 5. For tutors it would be 88 divided by 4.

Then to find how many tutors you need for 81 students you would need 4 tutors because you want to divide 81 by the unit rate we got (22), and since the answer would be a decimal (3.68.....) you would need to round the whole number up to four because you cant have a decimal of a person.

Plz help I dont understand this
damaskus [11]

We can do this by following the order of operations  procedure.  PEMDAS.

= Parentheses Exponent Multiply Division Add Subtract

So in this case we work out the parentheses first , then the multiply:-

5(8 + 7)

= 5 * 15

= 75 (answer)
