cathy needs to collect linear data which set of data should cathy collect
A. The height of a building for 20 years.
B.The height of a person from birth till 20
C. the height of a tree for 20 years.
D. The height of an elephant for 20 years.
Option A is correct.
Cathy needs to collect linear data . She should collect the data of option A-The height of a building for 20 years.
Explanation:
Linear data is that data whose slope is always same. Here lets assume, initially the building had 2 floors. Each year 2 floors are added above the previous floors. So our coordinate will be (0,2) (1,4) (2,6) (3,8) and so on.
So slope = [tex]\frac{difference in y}{difference in x}[/tex]
= [tex]\frac{4-2}{1-0} = \frac{2}{1}[/tex]
= [tex]\frac{8-6}{3-2}[/tex] = [tex]\frac{2}{1}[/tex]
So, here slope is 2 for all coordinates.

First you had to subtract by seventeen from both sides of equation form.
[tex]17+p-17=7p-13-17[/tex]
Then simplify.
[tex]p=7p-30[/tex]
Next, subtract by seven-p from both sides of equation form.
[tex]p-7p=7p-30-7p[/tex]
Simplify.
[tex]-6p=-30[/tex]
Then you divide by negative six from both sides of equation form.
[tex]\frac{-6p}{-6}= \frac{-30}{-6}[/tex]
And finally, simplify by equation.
[tex]-30/-6=5[/tex]
Final answer: [tex]\boxed{p=5}[/tex]

Which equation is the inverse of y=9x^2-4
The equation of the inverse of the function is [tex]y=\sqrt{\frac{x+4}{9} }[/tex]
Given the expression y = 9x^2 -4
Replace y with x to have
x = 9y^2 -4
Make y the subject of the formula to get the inverse function
9y^2 = x+ 4
[tex]y^2 = \frac{x+4}{9} \\y =\sqrt{\frac{x+4}{9} }[/tex]

How many lines of symmetry does this figure have?
There aren't any lines of symmetry because it is a scalene right triangle. (:
Answer:
The scalene triangle has no lines of symmetry.
Step-by-step explanation:
We can see that the given figure is a scalene right triangle.
A line of symmetry is a line that divides a figure into two mirror image halves. The line around which a figure is reflected over is called a line of symmetry.
The scalene triangle has no lines of symmetry. A scalene triangle is one which has no sides equal and no angles equal.
Which expression represents the distance between -14.6 and -5.2 on the number line?
If the expression represents the distance between -14.6 and -5.2 on the number line. The expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.
What is distance?
Distance between these two points:
Distance = Larger value - Smaller value
Where:
Larger value = -5.2
Smaller value= -14.6
So,
Distance = -5.2 - (-14.6)
Distance = -5.2 + 14.6
Distance = 9.4
Therefore the expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.
find the quotient: -10/19 divided by (-5/7) ?
In mathematics, we convert division of fractions to multiplication by using the reciprocal of the divisor. By following these steps, -10/19 divided by (-5/7) simplifies to 14/19.
Explanation:The problem at hand involves the division of two fractions, -10/19 divided by (-5/7). In mathematics, the division of fractions is performed by converting the division operation into multiplication by making use of reciprocal of the divisor. That means we replace the division symbol between the two fractions with a multiplication symbol and inverse the divisor (which is the fraction that comes after the division symbol).
Let's perform the operation step-by-step:
Invert the divisor (i.e., flip fraction (-5/7) to (7/-5) or -7/5)Replace the division symbol with a multiplication symbol, we get: -10/19 * -7/5Multiply the numerators: (-10) * (-7) = 70Multiply the denominators: 19 * 5 = 95Combine the resulting numerators and denominators to form a fraction: 70/95Simplify the result: 14/19So, the result of -10/19 divided by (-5/7) is 14/19.

the width of a rectangle is 12 cm less than the length the perimeter is 156 cm. Find the with and length
We know that the perimeter of a rectangle is twice the length, plus twice the width.
P = 2L + 2W
We also know that the perimeter is 156.
P = 156
Finally, we know that the width is 12 less than the length.
W = L - 12.
The next thing that we do is substitute the information that we have into the original equation:
P = 2L + 2W
156 = 2L + 2(L - 12)
From this point we start to solve
156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis
156 + 24 = 2L + 2L - 24 + 24
180 = 2L + 2L <--- getting like terms on same sides
180 = 4L <---combining like terms
180/4 = 4L/4 <--- getting like terms on same sides
45 = L <---now we have a value for L
Now we take the known value for L and substitute it in to our equation for W
W = L - 12
W = 45 - 12
W = 33
So now we have Length = 45 and Width = 33.
w = l - 12
156 = 2l + 2w
Since we have a value of w, we can plug that into the variable w to find the exact value of l.
156 = 2l + 2(l - 12)
Distributive property.
156 = 2l + 2l - 24
Combine like terms.
156 = 4l - 24
Add 24 to both sides.
180 = 4l
Divide both sides by 4.
l = 45
Now that we have the exact value of l, we can find the exact value of w.
w = l - 12
w = 45 - 12
w = 33
We now know the width is equal to 33 cm, and the length is equal to 45 cm. (This is your answer.)
We can verify by plugging these values into the second equation.
156 = 2l + 2w
156 = 2(45) + 2(33)
156 = 90 + 66
156 = 156 √ this is correct.

you have piano lessons every 7 days and tuba lessons every 3 days. Today you have both lessons. Not counting today or the day when you have the same lesson again, how many piano lessons will you have in between? how many tuba lessons will you have in between?
You will have 2 piano lessons and 6 tuba lessons
To solve this, we find the least common multiple (LCM) of 7 and 3, which is 21. Not counting the initial or ending day, there are 19 days in between, during which time 2 piano lessons and 6 tuba lessons occur.
Explanation:The key concept in this question is the Least Common Multiple (LCM) of two numbers. Given that you have piano lessons every 7 days and tuba lessons every 3 days, we are seeking to find out when these cycles will align again. The LCM of 7 and 3 is 21, meaning that you will have both lessons on the same day every 21 days.
Not counting today or that next joint lesson day (a total of 21 days), we then have 19 days remaining. For piano lessons, since they occur every 7 days, you will have 19 / 7 = 2 piano lessons in between, with some non-whole number of days leftover. Similarly, you will have 19 / 3 = 6 tuba lessons in between, again with a non-whole number of days leftover. Therefore, the answer is 2 piano lessons and 6 tuba lessons.

Answer: T(c)=c+160/4
The function T(c), which is the inverse of C(t), is T(c) = (c + 180) / 6.
Explanation:To find the inverse function T(c), we first have to rewrite the original function C(t) in terms of c. So, if C(t) = 6t - 180, we write it as c = 6t - 180.
Next, we swap the roles of c and t, so now t becomes the function of c i.e., we get t = 6c - 180.
Finally, we solve this equation for c to get the inverse function. Doing so will give us c = (t + 180) / 6. Hence the inverse function is T(c) = (c + 180) / 6.

Lea bought 225 flowers and 12 vases. She put about the same number of flowers in each vase. Which is the best estimate for the number of flowers in each vase
This answer can be found by deviding 225 by 12. The exact answer is 18.75, but obviously you can’t put 3/4 of a flower in a vase. In that case, the best estimate would be 18-19 flowers, or just 19.

Identify the coordinates of four points on the line with each given slope and y-intercept. 0.2, y-intercept = 0.3
Slope = 0.2 and y-intercept = 0.3
The slope intercept form of line is
y=mx + b where m is the slope and b is the y intercept
So equation becomes y = 0.2 x + 0.3
To find coordinates of 4 points , we plug in some number for x and find out y
x y = 0.2 x + 0.3
0 y = 0.2 (0) + 0.3= 0.3
1 y = 0.2 (1) + 0.3= 0.5
2 y = 0.2 (2) + 0.3= 0.7
3 y = 0.2 (3) + 0.3= 0.9
Four coordinates are (0,0.3) (1,0.5) (2,0.7) (3,0.9)
