Find the constant of proportionality for the relationship plotted in the distance versus time graph shown below, and hence predict the distance covered at 10 seconds.
Answer: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

the formula for converting degrees fahrenheit (f) to degrees kelvin (k) is:
solve for f, in terms of k
k=5/9(f+459.67)
Answer:
See below
Step-by-step explanation:
K = 5/9 (F + 459.67) Multiply both sides by 9/5
9/5 K = F + 459.67 Subtract 459.67 from both sides
9/5 K - 459.67 = F

Answer:
missing side is 5x - 4
Step-by-step explanation:
x - 1 + ( 3x + 6 ) + third side = 9x + 1
x - 1 + 3x + 6 + third side = 9x + 1
4x + 5 + third side = 9x + 1
third side = 9x + 1 - ( 4x + 5 )
third side = 9x + 1 - 4x - 5
third side = 5x - 4

Answer:
h=5/18
Step-by-step explanation:
Hi there!
If you try to solve 1/2-h=2/9 for h immediately, you will find that you cannot because the denominator is odd for 2/9. Multiply 2 for the numerator and the denominator to get 4/18. Now we have 1/2-h=4/18. Multiply the numerator and denominator by 9 to get 9/18-h=4/18. H=5/18.
Answer:
[tex]\boxed{h=\dfrac{5}{18}}[/tex]
Step-by-step explanation:
[tex]\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}[/tex]
1. Subact [tex]\dfrac{1}{2}[/tex] from both sides:
[tex]\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}\\\\\textsf {$\dfrac{1}{2}-\dfrac{1}{2} - h$ = $\dfrac{2}{9} -\dfrac{1}{2}$}\\\\\textsf {$-h$ = $\dfrac{4-9}{18}$}\\\\\textsf {$-h$ = $\dfrac{-5}{18}$}[/tex]
2. Divide both sides by -1
[tex]\textsf {$-h$ = $\dfrac{-5}{18}$}\\\div -1 \div-1\\\\ \boxed{h=\dfrac{5}{18}}[/tex]
Final answer: [tex]\boxed{h=\dfrac{5}{18}}[/tex]

what is the volume of a cylinder with a radius of 5
and a height of 12
Answer:
300pi
Step-by-step explanation:
the formula for volume of a cylinder is pi3^2h
So pi * (25) * 12
300 pi.
If you forget the formula, remember circle area is pir^2 and multiplying that by the height will raise the circle's area, giving us volume.

Which equation is the inverse of y = x2 – 36? y = plus-or-minus startroot x endroot 6 y = plus-or-minus startroot x 36 endroot y = plus-or-minus startroot x endroot 36 y = plus-or-minus startroot x squared 36 endroot
The inverse of the given function is expressed as y = ±√x + 38
Inverse of an equationGiven the equation below expressed as:
y = x² - 36
Replace y with x
x = y² - 38
Add 38 to both sides of the equation
x + 38 = y² - 38 + 38
y² = x + 38
Take the square root of both sides
√y² = ±√x + 38
y = ±√x + 38
Hence the inverse of the given function is expressed as y = ±√x + 38

Which of the following indicates that AABC and ADEF are similar?
Answer:
C. ΔABC ~ ΔDEF
Step-by-step explanation:
The operators in the different answer choices are used to describe different kinds of relations.
A. "almost equals" or "is approximately"
B. "equals"
C. "is similar to" (tilde operator)
D. "is congruent to"
__
Additional comment
"Congruent" is used to describe geometrical figures in which all corresponding measures are identical. "Equal" generally refers to the relationship between algebraic or numerical values or expressions.
"Is approximately" is used to describe values that are the same within a suitable tolerance or error range. For example, 23.4 ≈ 23.352, where the value on the left has been rounded to the nearest tenth. (It is within 0.05 of the value on the right.)

You are investing $1500 at 5.2% compounded annually. How much money will you have in 12 years?
Answer:
$2756.01 to the nearest cent.
Step-by-step explanation:
A = P(1 + r)^t where A is the amount after t years, P = amount invested, r = rate as a decimal fraction.
So here, we have:
A = 1500(1 + 0.052)^12
= 1500 * 1.837337
= $2756.01

Answer is 105 degrees.
Explanation:
Given two parallel lines AB and CD and a transversal cutting the two lines.
We know that when a transversal cuts two parallel line,
i) corresponding angles would be equal
ii) Interior angles total to 180
iii) alternate angles are equal.
In the picture given we have corresponding angles as
(2,6) . Hence angle 2 = angle 6.
Angle 6 = 75 (given)
Hence angle 2 =75.
Angles 1 and 2 are supplementary because they form a linear pair.
Hence angle 1 = 180-75
Angle 1 =105
