Answer:
18.4
Step-by-step explanation:
Well the square root of 84 isn't an exact answer.
But when rounded it equals to approximately 9.16 or rounded even more 9.2 at most.
So 9.2 + 9.2 = 18.4.
So the answer is ≈ 18.4

What conjecture can you make about the tangent of complementary angles?
Answer:
Step-by-step explanation:
If the sum of two angles is one right angle or 90°, then one angle is said to be complementary of the other. Thus, 25° and 65°; θ° and (90 - θ)° are complementary to each other.

The correlation coefficient that represents the weakest correlation amongst the given options is -0.1.
What is correlation?Correlation is a statistical measure used to measure the relationship that exists between two variables. A value of one represents a perfect correlation. A value of zero signfies that the variables have no relationship.
So, the correlation coeffieicent with a value closest to zero would have the weakest correlation.

The diagram shown is two intersecting lines. The measure of 5 is 47°.
Please solve this on paper! I'll give brainliest to the best explanation. Thank you so much <3
Answer:
The measure of angle 7 is 47°
The value of x = 69
Step-by-step explanation:
(a) The measure of angle 7 is also 47° { therefore angle 5 angle 7 are vertically opposite angles so they are equal }
(b) if the angle 6 is represented by (2x-5) so the equation will be (2x-5) + angle 5 = 180° { linear pair}
(c)
=> 2x-5+47 = 180
=> 2x + 42 = 180
=> 2x = 180 -42
=> 2x = 138
=> x = 138/2
=> x = 69
Answer:
See below ↓↓↓
Step-by-step explanation:
(a) ∠7 = ∠5 (vertically opposite angles)
∠7 = 47°It is equal to 47 degrees, because the when a transversal cuts through a straight line, the angles which lay opposite to each other are equal(b) ∠5 and ∠6 form a line, so their sum is equal to 180°, which is the angle of a straight line. Therefore, our equation :
47 + 2x - 5 = 180(c) Solving for x :
2x + 42 = 1802x = 138x = 69°The answer to (-2)+(-5) will be

Two people are trying to raise an object from a hole using two ropes, as shown in the diagram below. Person 1 exerts a force of
355 N and Person 2 exerts a force of 425 N.
What is the magnitude of the combined force applied by both people?
Answer:
554 N
Step-by-step explanation:
We're looking for the magnitude of the force - angles don't matter.
We need to resolve the two forces.
As you can see in the attached drawing, this basically just becomes Pythagoras.
[tex] {f}^{2} = {355}^{2} + {425}^{2}[/tex]

1. When oil was spilled out in the middle of a lake, it spread out on the surface of the water in a circular pattern. The radius of the circular pattern increased at a rate of 4 feet per minute. ((() = 4tft/min)
A. [3 pts) How fast was the area of the circular pattern increasing per minute? Construct the composite function to show how the area was increasing each minute. ( A() = ft/min).
The rate of change of the area as a function of time is:
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)
How to get the rate at which the area increases?
Remember that for a circle of radius R, the area is:
A = 3.14*R^2
Now, if the radius increases at a rate of 4 ft/min, then we can rewrite R as:
R(t) = R₀ + 4ft/min*t
Where t is the time in minutes, and R₀ is the initial radius.
So the area function is:
A(t) = 3.14*(R₀ + 4ft/min*t)^2
The rate of change is given by the differentiation with respect to t, it is:
A'(t) = 2*3.14*(R₀ + 4ft/min*t)*(4ft/min)
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)
The rate at which the area increases, as a function of time, is given by:
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

The scatter plot below shows the cost (y) of long distance phone call based on the number of minutes (x) the calls take. Part A. Draw a line of best fit on the scatter plot
Part B write the approximate equation of the line of best fit
It should be in slope intercept form.
Part C. Use your equation from part B to predict the cost of a long distance call that lasts 120 minutes. Be sure to show your work
Part D. Explain how you found your answer to Part C.
The scatter plot that shows the cost of long distance phone call is an illustration of a linear regression
Part A: Draw a line of best fitSee attachment for the line of best fit
Part B: The equation in slope intercept formFrom the attached graph, the line passes through the points:
(x,y) = (0,0) and (40,4)
The equation is then calculated using:
y = y2/y1 * x
This gives
y = 4/40 * x
Evaluate
y = 0.1x
Part C: Predict the cost of long distance call of 120 minutesThis means that x = 120
So, we have:
y = 0.1 * 120
y = 12
Hence, the predicted cost of long distance call of 120 minutes is $12
Part D: Explanation of CThe answer in part C is calculated by substituting 120 for x in the equation of the line of best fit

Find the area of a regular pentagon with a radius of 9 yds. show all six steps.
Answer:
192.6 square yards
Step-by-step explanation:
The area of a regular pentagon can be found using the formula for any regular polygon.
A = (n/2)r²·sin(360°/n) . . . . radius r, n sides
For a pentagon, the number of sides is 5, so this becomes ...
A = 2.5r²·sin(72°)
__
Using the given value of radius, the area is ...
A = 2.5(9 yd)²·sin(72°) = 2.5 · 81 · 0.951057 yd²
A ≈ 202.5 · 0.951057 yd²
A ≈ 192.589 yd²
The area of the pentagon is about 192.6 square yards.

How do I solve?
Answer:
p > 8
Step-by-step explanation:
8p - 48 > 4p - 16
plus 48 on both sides
8p > 4p + 32
minus 4p on both sides
4p > 32
divide 4 on both sides, 32 ÷ 4 = 8, so,
p>8
Answer:
P > 8 ??? I don't know if this is right and if its not then sorry lol
Step-by-step explanation:
Multiply 8(p-6) and 4(p-4)
You will get 8p - 48 > 4p - 16
Then add 48 to -16
Then you will get 8p > 4p + 32
Then subtract 4p from 8p
Then you will get 4p > 32
Then divide 4 from 4p and 32
Then you will get p > 8
Alice is making a necklace. She has a chain that is 400 mm long. She puts forty 1.7 mm beads, twenty-seven 6.5 mm beads, and eight 3.4 mm beads on the chain. How much of the 400 mm chain is left without bead?
Answer:
129.3mm chain left without beads
Step-by-step explanation:
Equation:
400mm long chain - [(40 x 1.7mm) + (27 x 6.5mm) + (8 x 3.4mm)]
= chain left without beads
Calculation:
40 beads x 1.7mm = 68mm
27 beads x 6.5mm = 175.5mm
8 beads x 3.4mm = 27.2mm
(68mm + 175.5 mm + 27.2mm) = 270.7mm chain with beads
400mm chain - 270.7mm chain with beads
= 129.3mm chain left without beads

What is the range of the function f(x) = 3x2 6x – 8?
The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).
What are domain and range?The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.

the diameter of fishing line varies. Fishing lines can have a diameter as small as 2 x 102 and as large
Answer:
We know that:
small diameter = 2 * 10^-2 in
large diameter = 6 * 10^-2 in
We want to know how many times larger is the thin diameter compared to the large one.
We will do this as follows:
large diameter = k * small diameter
where k is the number of times that we want to find
6 * 10^-2 = k * 2 * 10^-2
k = (6 * 10^-2) / (2 * 10^-2)
k = 3
This means that the large diameter is 3 times the small one.
