2) Ruth borrows $440 at 0.6% simple interest per month. When
Ruth pays the loan back 4 years later, how much interest does
Ruth pay?

Answers

Answer:

$10.56

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 0.6%/100 = 0.006 per year,

then, solving our equation

I = 440 × 0.006 × 4 = 10.56

I = $ 10.56

The simple interest accumulated

on a principal of $ 440.00

at a rate of 0.6% per year

for 4 years is $ 10.56.

Answer:

450.56

Step-by-step

440 x 0.006 x 4 + 440 =450.56

Hint: | Distribute exponents over products in (-2 w^3)^2.

Multiply each exponent in -2 w^3 by 2:

4 v^3 w×(-2)^2 w^(2×3)

Hint: | Multiply 2 and 3 together.

Rewrite the equation 2y - 4x = 10 in function notation where f(x)= y.
f(x)=

Answers

Answer:

Answer:

f(x) = 5 + 2x

y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.

Answer:

f(x) = 5 + 2x

Step-by-step explanation:

2y - 4x = 10

     +4x    +4x

2y = 10 + 4x

Now we have a new equation but we have to isolate the variable y.

[tex]\frac{2y}{2}[/tex]  = [tex]\frac{10 + 4x}{2}[/tex]  Then divide to solve for y.

y = 5 + 2x

Since f(x) is the same thing/equal to y we can just replace that.

f(x) = 5 + 2x

Can someone explain this to me!!! Will give the brainliest!!!!

Answers

Answer:

88 degrees

Step-by-step explanation:

First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).

Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.

We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

Read this excerpt from "The Think Tank" by Patricia Daniels.Azy, a 21-year-old male orangutan, had been scoring 100 percent on the day's vocabulary testuntil now. National Zoo biologist Rob Shumaker holds up some folded bags containing chopped fruit. "Okay, Azywant to tell me what this is?" In front of the rusty-haired ape is a computer screen showing some symbols. Each one stands for a word. Azy lifts his long, graceful hand and points to the symbol for cup. A buzzer sounds. The screen shows an hourglass symbol that means his answer is wrong.For the first time this afternoon, Azy seems confused. Shumaker shows him the bags again, and again the orang points to "cup". On the fourth try, Azy figures it out. He points to the symbol for "bag," and Shumaker hands him the paper bags through an opening in the Plexiglas between them. Azy picks out the fruit and reluctantly hands back the bags when the biologist asks politely, "Azy, can I have those?"For the last three years, Shumaker has been working with Azy and five other orangutans and the Zoo's Think Tank building. In addition to these great apes, Think Tank Researchers are studying creatures as various as hermit crabs, leaf-cutter ants, and macaques. They hope to learn whetherand howanimals think. Some of the scientists look at tool use. Others observe the animals' social life. Shumaker would like to know if orangutans can learn language.Which answer best summarizes this text?(A) Azy is a male orangutan who is taking a vocabulary test at the National Zoo. Shumaker has been studying Azy and five other orangutans for three years to see whether the great apes can learn language. Other researchers at the Zoo's Think Tank building are studying other animals to learn more about how they think.(B) Azy is a 21-year-old male orangutan. He is taking a vocabulary test, but he gets the words "bag" and "cup" mixed up. A buzzer goes off because he is wrong. Azy has been studied like this for three years. Shumaker studies him at the Think Tank building at the zoo. Researchers are also looking at other animals to see if they can use tools and learn language and things like that. Azy is part of this study along with other orangutans and hermit crabs, leaf-cutter ants, and macaques.(C) Azy is a great ape called an orangutan. He has rusty-colored hair. He is taking a vocabulary test. A researcher holds up some bags, but Azy says they are cups. He is wrong. Scientists at the Think Tank building are studying animals. Azy is one of the animals being studied. The researcher wants to know if orangutans can learn language. He is studying Azy and five other orangutans.(D) Azy was getting 100 percent on his vocabulary test. But then the orangutan got an answer wrong. Shumaker held up some bags of fruit, but Azy picked a symbol for "cup". A buzzer went off to let him know he was wrong. Azy is actually an orangutan. Shumaker is studying Azy to see if he can learn language. He is also studying five other orangutans. Other scientists are studying macaques, ants, and hermit crabs.
