  • x= a sin theta
  • y=b sin theta

\\ \sf\longmapsto b^2x^2+a^2y^2

\\ \sf\longmapsto b^2(asin\Theta)^2+a^2(bcos\Theta)^2

\\ \sf\longmapsto b^2a^2sin^2\Theta+a^2b^2cos^2\Theta

\\ \sf\longmapsto a^2b^2(sin^2\Theta+cos^2Theta)

\\ \sf\longmapsto a^2+b^2(1)

\\ \sf\longmapsto a^2b^2

Which exponential function is graphed here?
jek_recluse [69]

Answer:

y = 5^x

Step-by-step explanation:

y= b*(a)^x + c

c could = 1 but then you would not have an exponential function. c = 0 because the graph follows the x axis up until x = -2. Suppose c = 1. The the graph would follow y = 1 up until x = - 2

When x = 0, y = 1 which means that b. If b is anything but 0 or 1 then the y intercept would be stretched to a different place. If be = 0 then y would = 0.

So the graph is of the form y = a^x

Now when x = 0 the graph, the y intercept is y = a^0  or y = 1 So the y intercept is (0,1)

Now the next point is thing to solve for is a.

When x = 1, y = 5  (read the graph)

y = a^x

5 = a^1

5 = a because a^1 is a.

Answer

y = 5^x.

5 = a^1

At the beginning of the week, you have $42 in your savings account. During the week, you deposit $25 and withdraw $36. How much
Natalija [7]

Answer: you have $31 at the end of the week

Step-by-step explanation:

First, let's put this problem into an algebraic expression. We started off with $42. We then added $25 and took out $36 during the week. The expression for this problem is

42

+

25

−

36

.

Next, add 42 and 25 together to get

67

. We now have

67

−

36

.

Finally, subtract 36 from 67 to get

31

, our answer.
