4
Answer:
k = \(\frac{3}{4}\)
Step-by-step explanation:
given variation equation
y = kx
to find k substitute y = 3 and x = 4 into the equation and solve for k
3 = 4k ( isolate k by dividing both sides by 4 )
\(\frac{3}{4}\) = k

The coordinate grid shows the location of three points.
PLS HELP MEEE
Step-by-step explanation:
solution

hope u get it
Answer:
5 units.
Between A and C there are 5 squares until it reaches C meaning that the distance between points A and C is five units.
If these unit squares on the grid equalled a different number each (for example, 2) then the distance from the said points would be 10 and you can find this by multiplying 5 x 2. If it was any other number then you would do the same (5x).
We can also find the answer to this when only given the points.
Since A = -2, -3 and C = 3, -3 we can already see in this way that their value for y is the same. Since A's value for x is -2 then we can add until we get to 0 and continue adding until we reach 3 (aka C's value for x), this would equal 5 units.

Does the shape have > one pair of perpendicular sides?In order to determine if the shape belongs to a group of shapes with more than one pair of perpendicular sides, we need to examine the number of right angles in the shape.
A right angle is a 90-degree angle, and shapes with perpendicular sides have right angles at their intersections. By counting the number of right angles in the shape, we can determine if it has more than one pair of perpendicular sides.
If the shape has only one right angle, then it does not have more than one pair of perpendicular sides. But if it has two or more right angles, then it would belong to the group of shapes that have more than one pair of perpendicular sides.

what is the graph of f(x) = 5(2)^x
The graph of the function f(x) = 5(2)^x is an upward-sloping exponential curve that starts at (0, 5) and increases rapidly as x moves to the right, never crossing the x-axis.
The function f(x) = 5(2)^x represents exponential growth. Let's analyze its graph.
As x increases, the value of 2^x grows exponentially. Multiplying it by 5 further amplifies the growth. Here are a few key points to consider:
When x = 0, 2^0 = 1, so f(0) = 5(1) = 5. This is the y-intercept of the graph, meaning the function passes through the point (0, 5).
As x increases, 2^x grows rapidly. For positive values of x, the function will increase quickly. As x approaches positive infinity, 2^x grows without bound, resulting in the function also growing without bound.
For negative values of x, 2^x approaches zero. However, the function is multiplied by 5, so it will not reach zero. Instead, it will approach y = 0, but the graph will never touch or cross the x-axis.
The function is always positive since 2^x is positive for any value of x, and multiplying by 5 does not change the sign.
Based on these observations, we can conclude that the graph of f(x) = 5(2)^x will be an exponential growth curve that starts at (0, 5) and increases rapidly as x moves to the right, never crossing or touching the x-axis.
The graph will have a smooth curve that rises steeply as x increases. The rate of growth will be determined by the base, in this case, 2. The larger the base, the steeper the curve. The function will approach but never reach the x-axis as x approaches negative infinity.

(Round up to the nearest integer.)
.
The sample size for the part (a) is 269, and the sample size for part (b) is 191 if a margin of error of 5 percentage points and use a confidence level of 90%
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
\(\rm MOE = Z{score}\times\frac{s}{\sqrt{n} }\)
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
We have:
MOE = 5% = 0.05 and
\(\alpha = 1-0.9 \Rightarrow 0.1\)
Let's assume the value of p = 0.5, and q = 0.5
From the table:
\(\rm Z_{\alpha/2}\Rightarrow Z_{0.1/2}\Rightarrow Z_{0.05}\Rightarrow 1.64\)
\(\rm n = p\times q \frac{Z^2_{\alpha/2}}{MOE^2}\)
\(\rm n = 0.5\times 0.5\frac{1.64^2}{0.05^2}\)
n = 268.96 ≈ 269
For part(b)
The value of p = 0.23, and q = 0.77
From the table:
\(\rm Z_{\alpha/2}\Rightarrow Z_{0.1/2}\Rightarrow Z_{0.05}\Rightarrow 1.64\)
\(\rm n = p\times q \frac{Z^2_{\alpha/2}}{MOE^2}\)
\(\rm n = 0.23\times 0.77\frac{1.64^2}{0.05^2}\)
n = 190.53 ≈ 191
Thus, the sample size for the part (a) is 269, and the sample size for part (b) is 191 if a margin of error of 5 percentage points and use a confidence level of 90%

8. The first three terms of a geometric sequence are ( x-6), 3x, and y. If the common ratio is 6, then the value of y is.
Answer:
The value of y is 216
(and the value of x is 12)
Step-by-step explanation:
The general formula for a geometric sequence is,
\(a_n = a_1(r)^{n-1}\)
Where n represents the nth term, a_1 is the first term and r is the common ratio,
we see that,
r = 6,
the first term is,
a_1 = (x-6)
the 2nd term is,
a_2 = 3x,
the 3rd term is,
a_3 = y, finding y,
first we find x, using the above given formula we have,
\(a_2 = a_1(6)^{2-1}\\3x = (x-6)(6^1)\\3x = 6x -36\\36 = 6x - 3x\\36 = 3x\\x=36/3\\x=12\)
x = 12,
Now, for y we can use the relation between a_3 and a_2,
\(a_3 = a_1(6)^{3-1}\\y = (x-6)(6)^2\\y = (12-6)(6^2)\\y = 6(6^2)\\y = 6^3\\y = 216\)
y = 216

To verify the answer, The distance between AB = √((3– 3)² + (7– 3)²).
line AB = √0+16= 4units
line AD = √((8– 3)² + (3– 3)²).
line AD = √25+0
