Answer:

correct me if I'm wrong......

The amount of money returned as interest depends on the initial

amount, the interest rate and the number of years.

Response:

Given:

The return on investment = $6,336

Amount the Certificate of Deposit pays = 4.4% simple interest

The initial investment (the principal), P= $16,000

Required:

The duration the initial amount of money had been invested.

Solution:

Interest = Principal × Rate × Time

Which gives;

[tex]Time = \mathbf{ \dfrac{Interest }{ Principal \times Rate}}[/tex]

Therefore;

[tex]Length \ of \ time \ of \ the \ investment = \mathbf{ \dfrac{\$6,336}{\$16,000 \times 0.044(/year)}} = 9[/tex]

Hope this helps.

Seven boys hire DVD's and each pays R5,50

I assume R 5.50 ( R to be the currency)

also assuming that they dont hire any more DVDs

total amount paid by 7 boys

= 5.50 × 7

= 38.5

when 4 more friends join the amount should get divided by 11 ( 7 + 4 )

so each has to pay an amount of 38.5 / 11 = 3.5

I think my assumptions here were correct

if not

let me know :)

Answer/Step-by-step explanation:

If the vertical line touches the graph at more than one point, then the graph is not a function.Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.

Yes it's a function

As per the defination of function.

If every domain of the relationship has an unique range that's a function

And rest also have unique range

So it's a function

Answer:

If I am correct both figures are similar because of AA (angle reasoning). They have the same angles meaning they are similar triangles even if they don't fit the SSS, SAS, etc. reasoning

Step-by-step explanation:

You could also do the cross multiply divide method to determine if they equal the corresponding length (which they do!) hope this helps! :)

edit: Question 4) is similar following the AA statement for triangles

Question 5 is not similar because it doesn;t match doing the cross multiply divide and has two right angles because they are

rectangles!

Question 1) Corresponding angles are related in two similar figures because they are the same. In triangles two figures similarity can be determined by identifying if they share two angles.

Question 2) Corresponding side lengths can determine the similarity by proving that the shape was only transformed by a scale factor and did not alter shape.

Question 3) No, not neccesarily. If they are the same size, length, and shape they are congruent. Similar figures are altered and different based on a scale factor

Answer:

-14>y-4

so -14+4>y-4+4

and -10>y

A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.

We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule

f(n + 1) = -4 f(n) + 3

We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)

f(1 + 1) = -4 f(1) + 3

f(2) = -4 • 1 + 3

f(2) = -1

We do the same thing to find the next term f(3) :

f(2 + 1) = -4 f(2) + 3

f(3) = -4 • (-1) + 3

f(3) = 7

One more time to find the next term f(4) :

f(3 + 1) = -4 f(3) + 3

f(4) = -4 • 7 + 3

f(4) = -25

Answer:

Measure of each angle is 71 and 19 degrees.

Step-by-step explanation:

Let's the angle  be "n"

Complementary angle = 90 °

n- (90-x) = 52

n - 90+ n = 52

Combine like terms

n - 90+ n = 52

2n-90=52

Add 90 to both sides of the equation

2n-90+90=52+90

simplify

2n = 142

Divide both sides of the equation by the same term

2n/2 = 142/2

Simplify

n = 71

2n = 142

Measure of each angle

1st = 71

2nd = 90-71 = 19

Answer:

(3,2)

Step-by-step explanation:

2x-4=y

2y+3x=13

We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation

2(2x-4) +3x=13 : *distribute*

4x-8+3x=13 :  *combine like terms*

7x-8=13  * add the 8 to the other side*

7x=21 *divide*

x=3

So  the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3  we plug it into the other equation preferably.

2(3)-4 =y : 6-4=y : 2=y

We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.

2x-4=y         2(3)-4=(2)    2=2

2y+3x=13    2(2)+3(3)=13    13=13

Hey there!

4(x + 3)

= 4(1x + 3)

DISTRIBUTE 4 WITHIN the PARENTHESES

= 4(1x) + 4(3)

= 4(x) + 4(3)

= 4x + 12

Therefore, your answer is:

Option B. 4x + 12

Good luck on your assignment & enjoy your day!
