Answer:

The simple interest earned when you invest $1,000 for 3 years at 10 % is $ <em><u>300</u></em> . The interest compounded when you invest the same sum for 2 years at 5 % is $ <em><u>331</u></em> .

Answer:

simple interest = $300

compound interest =$102.5

Step-by-step explanation:

Simple interest = P* T* R

P= principal, T= time, R= rate

P= $1000,  T= 3,  R = 0.1

simple interest = 1000 * 3 *0.1 = $300

compound interest = p[(1 + r)ⁿ - 1]

compound interest = 1000[(1 + 0.05)² - 1]

                                 =  1000[1.1025 - 1]

                                   = 1000 * 0.1025

                                   = $102.5

In the figure below, points M, P, H, J, and K lie in plane Z.
marishachu [46]

Answers:

  • (a) LN
  • (b) PHJ
  • (c) K
  • (d) HK

===================================================

Explanation:

Part (a)

Lines LN and PN have the point N in common. This is the intersection point.

-----------------

Part (b)

To name a plane, pick any three non-collinear points that are inside it. We cannot pick points H, J, K together because infinitely many planes pass through it. Imagine the piece of flat paper able to rotate around this axis (like a propeller). Having the points not all on the same line guarantees we form exactly one unique plane.

I'll pick the non-collinear points P, H and J to get the name Plane PHJ. Other answers are possible.

------------------

Part (c)

Points H, J and K are collinear as they are on the same line. Pick either H or K to fill out the answer box. I'll go with point K

------------------

Part (d)

Point P and line HK are coplanar. They exist in the same flat plane, or on the same sheet of flat paper together.

We can think of that flat plane as the ground level while something like point N is underground somewhere. So point N and anything on that ground plane wouldn't be coplanar.

Note: there are other possible names for line HK such as line JH or line JK. The order doesn't matter when it comes to naming lines.

Which set of ordered pairs could be generated by an exponential function?
olasank [31]

Answer:

The correct option is  (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of f(x)=ab^x

Where,  a is the initial amount a\neq 0 and  b is the rate of change b>0, b\neq 1

The graph of each exponential function passes through the point (0, a),

f(0)=a\cdot b^0 = a and a\neq 0  

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is  (1,2), (0, 1), (1, 2), (2, 4).
