White the equation of the circle with center -7,4 and diameter 12

Mathematics
1 answer:
Harman [31]2 years ago
6 0

Answer: (x -4)^2 +(y -7)^2 = 36

Step-by-step explanation: The equation of a circle with radius r and center at (h, k) is ...

 (x -h)^2 +(y -k)^2 = r^2

When the diameter is 12, the radius is 6 (half the diameter). Then for your center point, the equation is ...

 (x -4)^2 +(y -7)^2 = 36

Given:
jekas [21]

Answer:

we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Step-by-step explanation:

We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".

In other words, it is symbolically represented as:

' ~q ~p is the contrapositive of p q '

For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."

Given

p: 2x -5=5

q: 4x-6=14

As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p

Thus, we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

The regression equation below relates the scores students in an advanced statistics course received for homework completed and f
serg [7]

Answer: d.) None of the answer choices is correct

Step-by-step explanation:

The homework score is an independent variable (known) and on the x-axis, while the midterm exam is the dependent variable, so it's on the y-axis

y = 0.91x - 94.4; and x=420

Substitute x as 420 into the equation.

y = 382.2 - 94.4 = 287.8, or approximately 288.

And this value isn't in the options above.

Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8
Klio2033 [76]

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

f(x)=-x^2+1  for x =3-9 4-4-8

Simplify  4−4−8  to substitute in f(x)=−x^2+1

Subtract  4  from 4

0-8

Subtract  8  from 0

-8

Replace the variable  x  with  −

8  in the expression

f(-8)=-(-8)^2+1

Simplify

f(-8)=-64+1

f(-8)=-63

Answer = -63
