The area rate of change of side of square is 8 cm/s;
dA/dt = 112 cm²/s;
Area = (r)²; where r is the side of square;
dA/dt = (dA/dr)(dr/dt);
dA/dr = 2r and dA/dt = 112 cm²/s;
Therefore; dr/dt = 112/2r at r = 7;
dr/dt = 112/14 = 8 cm/s;
Rate of change of side of square is 8 cm/s;
area is the quantity that expresses the extent of a area on the plane or on a curved floor. The location of a aircraft region or plane place refers to the location of a shape or planar lamina, at the same time as surface place refers to the vicinity of an open floor or the boundary of a 3-dimensional object.

Find the 52nd term of the arithmetic sequence-8, -12, -16,...
Answer:
-212
Step-by-step explanation:
This question seems to be incrementing by steps of -4, starting at -8. To get the 52'nd term, we can simply start at the first term and add that -4 51 more times.
Assuming that negative eight is the first term then, we get:
-8 - 4 * 51
= -8 - 204
= -212
The 52nd term of the sequence will be -212.
What is a sequence?A sequence of events or things is a number of events or things that come one after another in a particular order.
Given a sequence, -8, -12, -16,...
nth term of a sequence is given by
an = a + (n-1)*d
a(-212) = -8 + (52-1)*-4
a(-212) = -8-204
a(-212) = -212
Hence, The 52nd term of the sequence will be -212.

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y). When attempting to solve systems involving two linear equations, this form is also quite helpful.
Standard form refers to any number that may be expressed as a decimal number between 1.0 and 10.0 when multiplied by a power of 10.

Answer:i think D but i would see what others say first
Step-by-step explanation:
Answer:
B) 1p - 0.4p
Step-by-step explanation:
40% to a decimal is 0.4, so that immediately marks "A" and "C" wrong.
Now what you're trying to find is the expression itself, so you want to first look for keywords, 'cause sometimes they can just give away the answer.
"A" says you're multiplying (a variable beside a number means to multiply)
"B" says you're subtracting 1p (1 x p) and 0.4p (0.4 x p)
"D" says you're adding 1p (1 x p) and 0.4p (0.4 x p)
So, now you look over the question.
Really you can mark "A" wrong. Now it's just between "B" and "D."
When you use percentages and an item, you're taking it OFF the price. So, the answer is B.

Answer:
AB = 4
[tex]m\angle E=30^\circ[/tex]
Step-by-step explanation:
Similar shapes
Two figures are similar if the ratios of the lengths of their corresponding sides are equal. The corresponding angles are also congruent.
Being ABCD and EFGH similar, the ratio of the lengths of AB and EF is equal to the ratio of the lengths of AD and EH, thus:
[tex]\displaystyle \frac{AB}{EF}=\frac{AD}{EH}[/tex]
Solving for AB:
[tex]\displaystyle AB=\frac{AD}{EH}\cdot EF[/tex]
Since AD=6, EH=1.5, and EF=1:
[tex]\displaystyle AB=\frac{6}{1.5}\cdot 1[/tex]
AB = 4
Since angle A is congruent to angle E:
[tex]m\angle E=m\angle A[/tex]
[tex]\mathbf{m\angle E=30^\circ}[/tex]

We observe that the expression for the given position is given by a quadratic expression.
The price of a movie ticket at the theater is $7 for students. The price is higher for adults. A group of 4 students and 3 adults paid $64 in all for movie tickets. How much does each adult ticket cost?
Given:
Student ticket price = $7
A group of 4 students and 3 adults paid $64 in all for movie tickets.
To find:
Each of the adult ticket cost.
Solution:
Let x be the cost of each adult ticket.
Then, cost of 3 adult tickets = 3x.
Cost of 1 student ticket = $7
Cost of 4 student ticket = $7(4)
According to the question,
[tex]7(4)+3x=64[/tex]
[tex]28+3x=64[/tex]
[tex]3x=64-28[/tex]
[tex]3x=36[/tex]
Divide both sides by 3.
[tex]x=12[/tex]
Therefore, the cost of each adult ticket is $12.

Answer:
No, they are not inverses.
Step-by-step explanation:
To find out if this are inverses we will have to switch the x and y in one of the equations. Let's do it with the second equation:
(Remember that f(x)/g(x) and y are virtually the same)
y = -4x + 2
Switch x and y
x = -4y + 2
Now solve for y
x - 2 = -4y
[tex]-\frac{x}{4} + \frac{2}{4} = y\\-\frac{x}{4} + \frac{1}{2} = y[/tex]
Therefore, the 2 functions in the question are not inverses of each other because the actual inverse has a negative in front of the -x/4.

what is the mean absolute deviation of 6 2 8 4 8 6 8 8
The mean of the data is 6.25. Then the mean absolute deviation of the data will be 1.75.
What is the mean absolute deviation?It is the average distance between each data point and the mean. Then the mean absolute deviation is given as,
[tex]\rm MAD = \dfrac{\Sigma _{i = 1}^n|x_i - \mu|}{n}[/tex]
The data is given below.
6, 2, 8, 4, 8, 6, 8, 8
The mean of the data will be given as,
μ = (6 + 2 + 8 + 4 + 8 + 6 + 8 + 8) / 7
μ = 50/8
μ = 6.25
Then the mean absolute deviation of the data will be given as,
MAD = (|6 - 6.25| + |2 - 6.25| + |8 - 6.25| + .... + |8 - 6.25|) / 8
MAD = (0.25 + 4.25 + 1.75 + 2.25 + 1.75 + 0.25 + 1.75 + 1.75) / 8
MAD = 14 / 8
MAD = 1.75

Find the amount of simple interest earned. Principal: $300. Annual interest rate: 6.5% Time: 3 years
Answer:
The simple interest is $58.5
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
where p is principal = $300
R is rate = 6.5%
T is time = 3 years
Substituting these values in the simple interest equation, we have that;
S.I = (300 * 6.5 * 3)/100 = $58.5
