Denise doesn't describe tabletop with an area of 36 x 16 squared white boy squared units running expression to represent one side length of the table top
Step-by-step explanation:
Side length = √Area = √(36x¹⁶y⁴)
= √[(6x⁸y²)²] = 6x⁸y².
Hence the expression for side length is 6x⁸y².
The length of the side of the table top will be 6x⁴y².
Based on the information given, it was stated that the area of the table top was given in the question.
It should be noted that the area of a square is gotten by squaring the sides. Therefore, the length of the side of the square will be 6x⁴y².

Answer:
C) 6 inches
Step-by-step explanation:
(√72)² = x² + x²
72 = 2x²
72/2 = x²
36 = x²
√36 = √x²
6 = x
x = 6 inches
Answer:
By Pythagoras theorem, we get

Step-by-step explanation:
Variables= x and y
Lets make y the larger variable.
x+y=80
y=5x+8
substitution
x+5x+8=80
6x+8=80
x=12
plug 12 back in to find y

Let sugar be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 57 + 2.5x?
Select one:
a. The amount of calories in fruit juice increases by 57 for every one gram of sugar. The calorie amount estimated by this model is 2.5 if there are zero grams of sugar.
b. The amount of sugar in fruit juice increases by 2.5 grams for every one calorie. The sugar amount estimated by this model is 57 grams if there are zero calories.
c. The amount of sugar in fruit juice increases by 57 grams for every one calorie. The sugar amount estimated by this model is 2.5 grams if there are zero calories.
d. The amount of calories in fruit juice increases by 2.5 when there are zero grams of sugar. The calorie amount estimated by this model is 57 if there is one gram of sugar.
e. The amount of calories in fruit juice increases by 2.5 for every one gram of sugar. The calorie amount estimated by this model is 57 if there are zero grams of sugar.
Answer: Choice E)
The amount of calories in fruit juice increases by 2.5 for every one gram of sugar. The calorie amount estimated by this model is 57 if there are zero grams of sugar.
=============================================================
Explanation:
x = amount of sugar (in grams)
y = number of calories in the juice
ŷ = estimate of y, so its the estimate of calories in the juice
The regression equation rearranges to ŷ = 2.5x + 57
This is in the form y = mx+b where m = 2.5 is the slope and b = 57 is the y intercept.
The slope tells us what the rate of change is. Specifically, it tells us how much the amount of calories (y) is going up each time the amount of sugar (x) goes up. Each time x goes up by 1, y goes up by 2.5
The y intercept 57 is the starting or initial amount of calories. If you have 0 grams of sugar, the lowest amount of sugar possible, then you start off with 57 calories. We can see this by plugging x = 0 into ŷ = 2.5x + 57 (you should get ŷ = 57). Visually, the y intercept is where the line crosses the y axis.
All of these facts point to choice E as the final answer.
Answer:
e.
Step-by-step explanation:
calories is y or response variable and sugar is the explanatory variable, x.
if x(sugar) is 1
y = 57 + 2.5(1) = 59.5, a 2.5 increase.
if it is 2
y = 57 + 2.5(2) = 62, another 2.5 increase.
if zero grams of sugar x = 0
y = 57 + 2.5(0) = 57 calories.

I will give brainiest to whoever answers correctly !!
Answer:
Step-by-step explanation:
The principal amount is
P=3000.
The time for which money is borrowed is ,
[tex]t=9 months[/tex]
The interest rate is ,
[tex]R=3\frac{1}{2}[/tex]
Determine the time in terms of year by division of time by 12.
[tex]t=\frac{9}{12} years\\= \frac{3}{4} years\\[/tex]
The formula for the interest is ,
[tex]I=\frac{P.r.t}{100}[/tex]
Substitute the known calues in the formula to obtain the value of interest.
[tex]I=\frac{3000.\frac{3}{4} .3\frac{1}{2} }{100} \\=\frac{3000.3.7}{2.4.100} \\=78.75\\[/tex]
So interest paid by the woman is $78.75
(b)
Determine the amount paid by the woman .
[tex]A=P+I\\=3000+78.75\\=3078.75[/tex]
So woman repay $3078.75 to the bank.

Perform the operation and get
your answer in the form a + bi.
(5 – 2i)(5 + 2i)
[?] + [ ]i
Answer:
Step-by-step explanation:
(5-2i) ( 5+2i) = (5^2) - ((2i)^2) = 25 - 4i^2
= 25 - 4(-1) = 25 +4 = 29 + 0i
The Solution is 29 + 0i.
What are complex numbers?The sum of a real number and an imaginary number is called a complex number. A complex number is usually represented by z and has the form a + ib. Here, both a and b are real numbers. The real part, denoted by Re(z), is represented by the value "a," and the imaginary part, represented by "b," is represented by Im(z). Also known as an imaginary number, ib.
Given Expression (5 – 2i)(5 + 2i)
we know a² - b² = (a - b)(a + b)
(5 – 2i)(5 + 2i) = 5² - (2i)²
= 25 - 4i²
and i² = -1
= 25 - 4(-1)
= 25 + 4 = 29
since the solution has 0i
so the equation is 29 + 0i
where a = 29 and b = 0
Hence, equation is 29 + 0i.

pls help
Answer:
Option 2: none of these
Step-by-step explanation:
-x +2y= 4
x-intercept occurs at y=0.
When y=0,
-x +2(0)= 4
-x= 4
x= -4
Thus, x-intercept is (-4,0).
y-intercept occurs at x=0.
When x=0,
0 +2y= 4
2y= 4
y= 4 ÷2
y= 2
Thus, y-intercept is (0,2).
