7 0

Answer:

Solution given:

Centre(h,k)=(-5,-9)

radius (r)=7

we have

Equation of a circle is;

(x-h)²+(y-k)²=r²

Substituting value;

(x+5)²+(y+9)²=7²

<u>(x+5)²+(y-9)²=49 is a required equation of a circle</u>.

What are the solutions to the equation e^1/4x =|4x|
Ivan

Answer:

x=0.27

Step-by-step explanation:

The given expression is

e^{\frac{1}{4}x}=|4x|

To solve this equation, we graph the functions:

f(x)=e^{\frac{1}{4}x}

and

g(x)=|4x|

From the graph, the two curves intersects at x=-0.24 and x=0.27.

But the domain of the logarithmic function is x>0

Therefore x=0.27

Line QR contains (2, 8) and (3, 10) Line ST contains points (0, 6) and (-2, 2). Lines QR and ST are (4 points)
Inessa [10]
Slope formula:
m  = y2 - y1 / x2 - x1

Line QR: (2,8) (3,10)
m = 10 - 8 / 3 - 2 = 2 / 1 = 2

Line ST: (0,6) (-2,2)
m = 2 - 6 / -2 - 0 = -4/-2 = 2

<span>c. parallel because the slopes are the same</span>

A recursive rule for the arithmetic sequence is a1=-3;an=an-1+7
Shkiper50 [21]
The explicit rule for any arithmetic sequence is:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number

In this case a=-3 and d=7 so:

a(n)=-3+7(n-1)

a(n)=-3+7n-7

a(n)=7n-10
