7 x² + 7 y² - 28 x + 42 y - 35 = 0  /: 7
x² + y² - 4 x + 6 y - 5 = 0
( x² - 4 x + 4 ) + ( y² + 6 y + 9 ) - 4  - 9 - 5 = 0
The equation in the standard form is:
( x - 2 )² + ( y + 3 )² = 18
The center is at the point ( 2, - 3 ).
Its radius is: √18 = 3√2 units.

Inside a toy truck, there is a gear that rotates to (3, −8) when the steering wheel is turned to the left. What is the sine valu
Marianna [84]
This is the the concept of trigonometry, to get the sine value of the the function given we shall proceed as follows;
Using Pythagorean theorem, the hypotenuse of the triangle will be found as follows;
The side length will be 8 units since the y-coordinate is -8
The side width will be 3 units since the x- coordinate is 3  
c^2=a^2+b^2
c^2=(3)^2+(-8)^2
c^2=9+64
c^2=73
c=sqrt(73)

Therefore the sine value will be:
sin x=3/sqrt(73)
multiply both numerator and denominator by sqrt(73) we get:
sin x=(3√73)/73

Therefore the answer is A]

Find the value of c so that the polynomial p is divisible by (x+2)
alexandr1967 [171]

Answer:

The value of c is 8.

Step-by-step explanation:

When a function is divisible by a factor, it will get 0 value. So, you have to substitute x = -2 into p(x) and equals to 0 :

p(x) = 4 {x}^{3}  + c {x}^{2}  + x + 2

p( - 2) = 4 {( - 2)}^{3}  + c {( - 2)}^{2}  + ( - 2) + 2

4( - 8) + 4c - 2 + 2 = 0

- 32 + 4c = 0

4c = 32

c = 32 \div 4

c = 8
