Victoria has $103 earned from babysitting saved at home, and the amount is modeled by the function h(x) = 103. She reads about a bank that has savings accounts that accrue
interest according to the function s(x) = (1.03)* - 1. After combining the two functions, the new function is g(x) = 103(1.03)* - 1. Using complete sentences, explain what the 103 represents in this new function. What is the interest rate the bank is giving to Victoria?
Answers
103 represents how much money Victoria is depositing into the bank, or her principal.
The interest rate is 1.03, or 3%.

The answer is D, if that is what you meant.
The 1/4 must be positive since the 1/2 is positive in the equation and the second numbers are all positive in the choices.
Also, 1/4 of 2 is 1/2, so D has to be the answer.

The height is 20
Step-by-step explanation:
This is because 120= .5x12
which equals 120= 6. Of course this is not equal so we do 120/6= 20.
Now if we insert 20 to check .5x12x20= 20 which makes the statement true
Answer: 20

The statements Fourteen eleventh graders prefer math and eight tenth graders prefer English and Thirty-five twelfth graders prefer math and nine tenth graders prefer English are true.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
For the 12th graders, we have a total of 67 pupils with 32 preferring
English, therefore the number of the 12th graders that prefer math is 67 - 32 = 35 pupils
Similarly for the 11th graders we have total pupils = 29 with 15 preferring English, therefore the number of the 11th graders that prefer math is 29 - 15 = 14 pupils
Also for the 10th graders we have total pupils = 26 with 18 preferring math, therefore the number of the 11th graders that prefer English is 26 - 18 = 8 pupils
Finally for the 9th graders, we have a total of 63 pupils with 40 preferring English, therefore the number of the 9th graders that prefer math is 63 - 40 = 23 pupils
Hence, the statements Fourteen eleventh graders prefer math and eight tenth graders prefer English and Thirty-five twelfth graders prefer math and nine tenth graders prefer English are true.

A research group is trying to determine the correlation between the number of hours spent
studying and the number of hours sleeping. Use the data shown on the graph to compute
the correlation coefficient.
A) r = 1 C) r = − 1
B) r = 0.5 D) r = −0.5
Answers
Answer:
C) r = − 1Step-by-step explanation:
In the graph, you can observe that all five points are perfectly lined up on a straight line, which is decreasing, because each points is lower than the previous one.
This situation represents a coefficient of correlation of -1, which means there's a strong negative correlation between variable.
Once again, graphically, this strong negative correlation can be deduct from the behaviour of the data, which is clearly decreasing with a straight line behaviour. In other words, the line that best fits is almost unique.
Therefore, the right answer is C.

A wire that is 48 centimeters long is shown below.
The wire is cut into two pieces, and each piece is bent and formed into the shape of a square.
Answers
Answer:
The sides of the square measure 6 cm
Step-by-step explanation:
If we cut the wire in half, we have to:
48/2 = 24
We would have two 24 cm wires
With each wire a square will be formed, therefore the question I suppose must be how much each side of the square measures.
We know that the square has 4 equal sides, therefore:
4/24 = 6
The sides of the square measure 6 cm
The sides of the square measure 6 cm.
Calculation of the sides of squares:Since A wire that is 48 centimeters long
In the case when we cut the wire in half so it should be 50% of 48 i.e. 24
Also, the square does have 4 equal sides
So, the sides of the square should be
[tex]= 24\div 4[/tex]
= 6 cm
hence, The sides of the square measure 6 cm.

Electricity City increases the price of televisions by 25%. If a television now sells for
$425, what was the original price?
Answers
Answer:
340
Step-by-step explanation:
As it was increased by 25%, $425 is 125% of the original price, so we can get back to 100% by dividing 425 by 5 [85], so 85 is 25% of the price. We can now get the original price by subtracting 85 from 425 (or you could multiply 85 by 4) which is 340
You can check this answer by multiplying 340 by 1.25
If the answer is 425, then it is correct, else, not. [it is]
A circular pool has a radius of 10 feet. What is the areaof the surface of the water in the pool? Use 3.14 for π.
Answers
Answer:
314ft²
Step-by-step explanation:
A = πr²
A= π10²
A=100π
A=100*3.14
A=314
Hope this helps :)
Final answer:
To calculate the area of the circular pool's surface, use the formula A = πr² with π approximated as 3.14 and the given radius of 10 feet. The area is 314 square feet, as the calculation yields A = 3.14 × 100, which does not need adjustment for significant figures.
Explanation:
To find the area of the surface of the water in the circular pool with a radius of 10 feet, we use the formula for the area of a circle, which is A = πr². Let's use the given value for pi (π) as 3.14 and the radius (r) is 10 feet. So the calculation is A = 3.14 × (10 feet)².
Now, squaring the radius, we get (10 feet)² = 100 feet². Next, we multiply this by our value for pi, resulting in A = 3.14 × 100 feet² = 314 feet². Therefore, the area of the surface of the water in the pool is 314 square feet.
Recalling significant figures, since our given radius was precise to two significant figures, our final answer should also reflect two significant figures. However, since all the numbers in 314 are significant, there is no need for adjustments in this case, and the result remains 314 square feet.

find the exact length of the third side
Answers
Answer: 3 times the square root of 5! (Or the square root of 45 if you don’t want to simplify)
Step-by-step explanation:
First, you would need to use the Pythagorean Theorum, a^2 + b^2 = c^2, since it is a right triangle.
So in this case,
6^2 + 3^2 = c^2
This simplfys to:
36 + 9 = c^2
45 = c^2
Now you have to take out the square in the c. What you do to one side, you have to do to the other, so you have to put 45 in a square root. This simplies to 3 times the square root of 5.

To find the length of side a in a right triangle, we can use the Pythagorean theorem.
Explanation:To find the length of the side a, we can use the Pythagorean theorem. In a right triangle, the Pythagorean theorem states that the square of the length of the hypotenuse (h) is equal to the sum of the squares of the lengths of the other two sides (a and b). So, we have a² + b² = h². Rearranging the equation, we can solve for side a: a = sqrt(h² - b²). Plugging in the known values, we can calculate the value of side a.
