Answer:

The correct option is C.

Step-by-step explanation:

The given functions are

g(x)=10(2)^{x-1}

h(x)=2x

It is given that the point needed for next level is defined by the function g(x) and hardest setting promises to multiply the points needed in each level according to the function h(x) .

The total points will a player need on the hardest setting of level 5 are

g(5)\times h(5)=10(2)^{5-1}\times 2(5)

g(5)\times h(5)=10(2)^4\times 10

g(5)\times h(5)=10(16)\times 10

g(5)\times h(5)=160\times 10

g(5)\times h(5)=1600

Therefore the total points will a player need on the hardest setting of level 5 are 1600 and option C is correct.

Answer:

The radius is 5 cm

Step-by-step explanation:

The formula for the area of a circle is :  \p*radius^2

To work out the length of the radius you would first need to divide the area of  78.5 cm by pi (pi=3.14), this gives you 25cm^2\\. This is because by dividing the area by pi we are isolating the value of the radius squared.

The final step is to work out the radius. You can do this by finding the square root of the radius squared which is 25, this gives you 5 cm. This means that the radius is 5 cm. This is because the square root is a number that when squared equals that number.

1) Divide 78.5 by pi.

78.5/\pi=25cm^2

2) Find the square root of 25 cm squared.

\sqrt{25} =5 cm

In this question pi is 3.14

Answer:

29.11

Step-by-step explanation:

This is clearly cos. So make an equation of cos equals 9 / x. Then use cross product to get x times cos equals 9. Finally divide by cos and use the calcuator to get x equals 29.11.

Alexandra [31]
21,000-600 = 20,400
20,400/3400 = 6
t = 6

21,000=3,400(6)+600
21,000=20,400+600
21,000=21,000
