Compute the missing data in the table for the following exponential function . Leave your answer in decimal form.

Snezhnost [94]

Answer: Option C: 0.03125

Step-by-step explanation:

we have an exponential equation, so we have:

f(x) = A*r^x

we have that:

f(1) = A*r^1 = A*r = 0.5

f(2) = A*r^2 = 0.25

f(3) = A*r^3 = 0.125

f(4) = A*r^4 = 0.0625

f(5) = A*r^5 = ?

we want to find the value f(5)

first, let's take the quotient:

f(2)/f(1) = (A*r^2)/(A*r) = r = 0.25/0.5 = 0.5.

then we have:

f(x) = A*0.5^x

and f(1) = A*0.5 = 0.5

then A = 0.5/0.5 = 1.

now we know that our function is f(x) = 0.5^x.

then, if we want to find f(5) we have:

f(5) = 0.5^5 = 0.03125

Then the correct option is option c.

komal went on vacation and bought three shirts for $11.21 each she paid $2.40 for a keychain and $6.47 for a mug. she also spent

mash [69]

The total amount of money which komal spent during her vacation is

$65.67

Given, Komal bought 3 shirts for $11.21 each.

She also spent her money on a keychain for $2.40 and a mug for $6.47.

After that she spent $23.17 for getting her picture developed.

How much in total she spend her money = ?

Money spent on shirts:

Cost for one shirt = $11.21

cost for three shirts = 3 × 11.21

= $33.63

Now add the amount of all the items Komal bought for herself.

Total money spent = cost price of shirts + cost price for a keychain + cost price for a mug + cost price for getting a picture developed.

Total money spent = 33.63 + 2.40 + 6.47 + 23.17

Total money spent = $65.67

Hence the total money Komal spent is $65.67.

Find the value of x and y

bagirrra123 [75]

According to google, the red marks mean those two lines are the same length. If that's the case, we know that x is the angle in both corners of the lower triangle. We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40. That leaves 140 for the rest. Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees. It is divided in two parts, the lower one of which we just found to be 20. So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees
