Answer:
whats you mean
Step-by-step explanation:
Given:
The area of a square picture frame is 55 square inches.
To find:
The length of one side of the frame.
Solution:
Let the length of one side of the frame is x inches.
Area of square is
where a is side length.
Area of frame is
Taking square root on both sides.
, so . Since 55 is closer to 49, therefore, is closer to 7.
Therefore, the length of one side of the frame is 7 inches.
A.) y = 47(1.191)x
B.) y = 34(1.204)x
C.) y = 26.9x – 1.3
D.) y = 27x – 4
Answer:
Hence, the model that best represents the data is:
Step-by-step explanation:
We are given a table that shows the estimated number of lines of code written by computer programmers per hour when x people are working.
We are asked to find which model best represents the data?
So for finding this we will put the value of x in each of the functions and check which hold true that which gives the value of y i.e. f(x) as is given in the table:
We are given 4 functions as:
A)
B)
C)
D)
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
The exponential function gotten from the table is y = 34(1.204)ˣ
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the lines of code written by x people.
From the table using the points:
(2,50) and (12, 320)
At (2, 50):
50 = ab² (1)
At (12, 320):
320 = ab¹² (2)
From equation 1 and 2:
b = 1.204, a = 34
The exponential function gotten from the table is y = 34(1.204)ˣ

Lydia wrote3/40 pages of her science report in one minute and her writing rate in pages per minute would be 0.075 in decimal form.
A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given that Lydia spent an hour writing her 4-and-a-half-page science report.
We initially convert an hour into minutes in order to answer this question.
∵ one hour = sixty minutes
Here fraction 4 1/2 which is equal to fraction 9/2 i.e. 4.5 in decimal form
After that, we divided 4 1/2 by 60. The solution is 0.075 in decimal form. That equals 3/40 when expressed as a lowest terms fraction.
Therefore, she wrote 3/40 pages of her science report in one minute.

Answer:
The answer to your question is r = 10
Step-by-step explanation:
Data
(x² + 10x ) + (y² - 8y ) = 59
Process
1.- Complete the perfect square trinomials
(x² + 10x + (5)²) + (y² - 8y + (4)²) = 59 + (5)² + (4)²
2.- Simplify
(x² + 10x + 25) + (y² - 8y + 16) = 59 + 25 + 16
3.- Factor
(x + 5)² + (y - 4)² = 100
or (x + 5)² + (y - 4)² = 10²
4.- Compare the result with the standard form
(x - h)² + (y - k)² = r²
then r² = 10²
and r = 10
