Answer:
a. [tex]4^2[/tex]
b. 16
Step-by-step explanation:
The area of a square is equal to the side length squared. Normally, the area of a rectangle is length times width but since all sides are equal in a square it is just the side times the side. This can be simplified to side length squared.
Since the side length is 4 the exponent form of the area is simply 4 squared or [tex]4^2[/tex].
Then, compute this by multiplying 4*4. This equals 16 cms square.

Find two linear functions p(x) and q(x) such that (p (f(q(x)))) (x) = x^2 for any x is a member of R?
Let p(x)=kpx+dp and q(x)=kqx+dq than
f(q(x))=−2(kqx+dq)2+3(kqx+dq)−7=−2(kqx)2−4kqx−2d2q+3kqx+3dq−7=−2(kqx)2−kqx−2d2q+3dq−7
p(f(q(x))=−2kp(kqx)2−kpkqx−2kpd2p+3kpdq−7
(p(f(q(x)))(x)=−2kpk2qx3−kpkqx2−x(2kpd2p−3kpdq+7)
So you want:
−2kpk2q=0
and
kpkq=−1
and
2kpd2p−3kpdq+7=0
Now I amfraid this doesn’t work as −2kpk2q=0 that either kp or kq is zero but than their product can’t be anything but 0 not −1 .
Answer: there are no such linear functions.

In a Physics lesson, Chantelle adds weights to a spring and carefully measures the extension. She finds that the weight, y g is related to the extension, x cm by the formula y = 0.5x + 1 for 0 ≤ x ≤ 20. a Draw the graph of y against x for 0 ≤ x ≤ 20. b Use this graph to find the (i) weight for a 17 cm extension (ii) extension produced by a 5 g weight. c What would Chantelle's formula predict for the springs extension for a 1 kg weight?

write the equation (y=kx)
= kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Simply so, which graph represents an equation in the form y KX?
Slope of y = kx Theorem The graph of the direct-variation function with equation y = kx has constant slope k. Now solve this system of equations for k. So by the definition of slope, k is the slope of the line through these points. Thus, k is the slope of the line with equation y = kx.
Also, which statement is always true about the graph of an equation in the form y KX Y KX? The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k. The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.
Secondly, what is Y KX called?
In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation. In this function, m (or k) is called the constant of proportionality or the constant of variation.
What is direct variation?
Direct Variation. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).

Meg is a veterinarian. She found that 33% of the 21 dogs she saw this week were boxers.Steve is also a veterinarian. He found that 10,or 50% he saw this week were boxers.Does each person need to find the part, the whole, or the percent? Meg needs to find the?
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
The question is incomplete.
This is the complete question:
Meg is a veterinarian. In a given week, 50% of the 16 dogs she saw were Boxers. Steve is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part the whole, and the percent.
a. Does Meg need to find the part, the whole, or the percent.
b. Does Steve need to find the part, the whole, or the percent.
Solution to the problem
a. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
b. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
y is inversely proportional to x2.
When x = 5, y= 16.
Find y when x= 10.
Since y is inversely proportional to [tex]x^2[/tex], the value of y, when x = 10 is 4.
Given the following data:
x = 5y = 16To find the value of y, when x = 10:
Mathematically, translating the inverse relationship between x and y, we have:
[tex]y \;\alpha\; \frac{1}{x^2} \\\\y \;= \frac{k}{x^2}[/tex]
Substituting the given parameters into the formula, we have;
[tex]16 = \frac{k}{5^2} \\\\k = 16 \times 25[/tex]
k = 400
Now, we can find the value of y, when x = 10:
[tex]y = \frac{400}{10^2} \\\\y = \frac{400}{100}[/tex]
y = 4
