Answer:

So the formula to solve the area of a circle is A = π r²

so for example if the you have a diameter but no radius and the diameter is 6 you can divide 6 by / to get your r or radius

so now the radius will be 3 bc 6/2 is 3 so you plug that in

A=π 3²

3*3=9

A=π* 9

and 9 times π or 3.14 gives us 28.26 therefore the area of our imaginary circle is 28.26

Ted is a long distance driver. It took him 30 min longer to drive 275km on the Trans-Canada highway west of Swift Current, Saska

IRISSAK [1]

Speed traveling west = x - 10 km /hr

275 / ( x-10) - 300 / x = 1/2

275 *2x - 300 (x-10)*2 = ( x-10) *x

550x - 600x +6000 = x^2 -10x

x^2 +40x - 6000 = 0

( x -60) ( x+100) = 0

x = 60

ANSWER East = 60 km/ hr West = 50 km /hr

CHECK

300 /60 = 5 hours

275 /50 = 5.5 hours

The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 30 and the common rati

Alchen [17]

The sum will be:

sigma(i = 1 to infinity, 30*(2/5)^i)

-> $\lim_{i \to \infty} \frac{30(1- \frac{2}{5}^{i} )}{ \frac{3}{5} }$

Which is equal to 30/(3/5) = 50

CORRECT ANSWER PLEASE!!!!! 150 points

Answer: -7

Step-by-step explanation:

First, lets use the functions to find the answer to f(-8) and g(4)

f(-8) is the same as asking for the value of y when x is -8

Therefore, f(-8) = -5 (according to the graph)

Using the same rule, g(4) would be the value of y when x = 4 which,

according to the graph, g(4) = 3

Plug these values back into the original equation to get:

$-1*f(-8)-4*g(4)=?\\=-1*-5-4*3\\$

using the order of operations, we will multiply the values first

$(-1*-5)+(-4*3)\\=5+(-12)\\=5-12\\=-7$

<h2>Therefore, our final answer is -7</h2>
