Fudgin [204]3 years ago
5 0

Answer:

Translate circle C 3 units towards the right and 5 units up.

Dilate this translated circle C by a factor 2.5. It will overlap (become congruent to) circle A

This is enough to prove that the two circles are similar

A college is currently accepting students that are both in-state and out-of-state. They plan to accept four times as many in-sta
MissTica

Answer:

The constraints are given as   x ≤ 100  , y ≤ 400

Total number of incoming in the college = (x+ y)

Step-by-step explanation:

x =   the number of out-of-state students and

y  =  the number in-state students

Number of out of state students that can be  accepted = 100

So, the Number of in-state students that can be expected

=  4( out of state students)

 = 4 x 100  = 400

So, the constraints are given as below,

      x ≤ 100

and y ≤ 400

and total number of incoming in the college = (x+ y)

Please help!!
polet [3.4K]

Answer:

The absolute value of the quadratic term,  \left | -\dfrac{1}{2}   \right | is less than 1

Step-by-step explanation:

The given function is y = (-1/2)·x² - 7

The parent function is y = x²

The vertical compression or stretching of a quadratic function is given by the value of the coefficient, <em>a</em>, of the quadratic term, x² of a quadratic function, a·x²

A quadratic function is vertically compressed if the coefficient, \left | a  \right | < 1.

In the given function, y = (-1/2)·x² - 7, the absolute value of the coefficient of the quadratic term, \left | -\dfrac{1}{2}   \right | < 1, therefore, the equation, y = (-1/2)·x² - 7, will be vertically compressed compared to the parent function, y = x².

Suppose that the​ amount, in​ grams, of polonium 210 present in a given sample is determined by the function defined by ​A(t)equ
ozzi

Answer:

The amount present in a sample of 401 grams after 25 years is 180\ g

Step-by-step explanation:

we have

A(t) -----> the​ amount, in​ grams, of polonium 210 present in a given sample

t -----> the time in years

A(t)=401e^{-0.032t}

we know that

To find out the amount present in a sample of 401 grams after 25 years, substitute the value of t=25 years in the equation and solve for A(t)

For t=25 years

A(25)=401e^{-0.032(25)}

A(25)=180.18\ g
