PLEASE HELP, I WILL MARK YOU BRAINIEST Identify if the relationship represented in the tables below is linear. If the table is linear, write the equation of the line.
Answer:
a) Yes. y=-4x+2. b) No.
Step-by-step explanation:
a) For every section of the graph as x goes up 1, y does down 4. It has a proportional relationship and you can use the rise and run found to do rise/run and get a slope of -4 and when x is at 0, y is at 2, giving you a y-intercept of 2.
b) There is no proportional relationship using addition and subtraction so the graphed line would not be straight.
using y2-y1 over x2-x1 the first table is 10-14 over -2--3 which would be -4 over 1
The next one would be 4 over -1

1)make x the subject of h=4(x+3y)+2 2) make a the subject of a^2+b^2=c^2
Answer:
[tex]\frac{h-12-2}{4} = x[/tex] & a² = c² - b²
Step-by-step explanation:
h = 4 (x + 3y) + 2
Expand brackets
h = 4x + 12y + 2
Subtract 12y & 2 from both sides
h - 12y - 2 = 4x
Divide both sides by 4
[tex]\frac{h-12-2}{4} = x[/tex]
a² = c² - b²
Then √ both sides to lose the ²

Find the area of the triangle. A. 17.7 B. 6.1 C. 8.1 D. 21.4
Answer:
17.7
Step-by-step explanation:
Area of a triangle is 1/2×L×B
since a degree is given we are to multiply it with it and we are to use SIN
so 1/2×sin65×4.5×13.1
sin65= 0.6018
so 1/2×0.6018×4.5×13.1
=35.47/2
=17.7
The area of the triangle is 17.7 square inches option (A) 17.7 is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We know,
The area of the triangle:
A = ab(sinx)/2
a = 13.1 cm, b = 4.5 cm, x = 37 degrees
A = 13.1×4.5(sin37)/2
A = 29.475sin37
A = 17.7 square inches
Thus, the area of the triangle is 17.7 square inches option (A) 17.7 is correct.

PLEASE HELP ME IM SO CONFUSED The volume of a cube is x³ cubic units. The surface area of the cube is x³ square units. What is the value of x?
Answer: The value of x is 6.
Step-by-step explanation:
TO find the volume of a cube you cube any side length. so if the side length is 6.
6^3 = 216
To find the surface area of a cube you will square one of the side lengths and multiply it by 6.
so the side length is 6 and 6 squared is 36

~[tex]\frak{Amphitrite1040:)}[/tex]The radius of a circle is given as 10cm subject to an error of 0.2cm. the error in the area of the circle is?
Answer:
12.56 [tex]cm^2[/tex] is the error in area of circle.
Step-by-step explanation:
Given that:
Radius of the circle, r = 10 cm
Error in measurement of radius, [tex]\triangle r[/tex] = 0.2 cm
To find:
The error in area of circle = ?
Solution:
First of all, let us have a look at the percentage error in measurement of radius:
[tex]\dfrac{\triangle r}{r}\times 100 = \dfrac{0.2}{10}\times 100 = 2\%[/tex]
Now, we know that Area of a circle is given as:
[tex]A = \pi r^2[/tex]
[tex]\Rightarrow \dfrac{\triangle A}{A} \times 100 = 2 \times \dfrac{\triangle r}{r} \times 100\\\Rightarrow \dfrac{\triangle A}{A} = 4\%[/tex]
Area according to r = 10
[tex]A = 3.14\times 10^2 = 314 cm^2[/tex]
Now, error in area = 4% of 314 [tex]cm^2[/tex]
[tex]\Rightarrow \dfrac{4}{100} \times 314 = 12.56 cm^2[/tex]
So, the answer is:
12.56 [tex]cm^2[/tex] is the error in area of circle.

A bag contains 5 blue marbles, 2 black marbles, and 3 red marbles. A marble is randomly drawn from the bag the possibility of not drawing a black marbles is? The probability of drawing a red marble is?
Answer:
3/10
Step-by-step explanation:
as the total number of marbles is 10 and the red marbles are 3 so the probability of drawing red marble will be 3/10.
Answer:
The possibility of not drawing a black marble= 4/5
The probability of drawing a red marble = 3/10
Step-by-step explanation:
Blue marbles = 5
Black marbles = 2
Red marbles = 3
Total marbles = 5 + 2 + 3 = 10
The possibility of not drawing a black marble = No of (blue + red) marbles/ Total marbles = ((5+3)/10 = 8/10 = 4/5
The probability of drawing a red marble = No of red marbles/Total marbles =3/10
The mean age of 8 women in an office is 20 years old. The mean age of 12 men in an office is 32 years old. What is the mean age (nearest year) of all the people in the office? Answer it please because it would be helpfull alot
Answer:
27.2
Step-by-step explanation:
The mean age of 8 women in the office is 20 years old
The mean age of 12 men in an office is 32 years old
The first step is to calculate the mean of the both the men and women in the office, that way we will be able to know the sum.
The mean of the women can be calculated by taking the sum of the value and dividing by the number
= 20+20+20+20+20+20+20+20/8
= 160/8
= 20
The mean of the men can be calculated by taking the sum of the values and dividing by the number
=32+32+32+32+32+32+32+32+32+32+32+32/12
= 384/12
= 32
Therefore, to find the mean age of people in the office we add the sum of both the men and women and divide by the total number of people in the office
= 384+160/20
= 544/20
= 27.2
Hence the mean age of people in the office is 27.2

The graph is of a function in the form p(t) = a • b ^t What is the function?
Answer:
p(t) = 5 × [tex]2^{t}[/tex]
Step-by-step explanation:
Use the points on the curve to evaluate a and b
Using (0, 5 ), then
5 = a[tex]b^{0}[/tex] = a × 1 ( [tex]b^{0}[/tex] = 1 ), thus
a = 5
p(t) = 5[tex]b^{t}[/tex]
Using (1, 10 ), then
10 = 5[tex]b^{1}[/tex] = 5b ( divide both sides by 5 )
b = 2
Thus
p(t) = 5 [tex]2^{t}[/tex]
The exponential function is
[tex]p(t) = 5(2^{t})[/tex]
What is exponential function?
An exponential function is defined by the formula [tex]f(x) = ab^{x}[/tex] where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
Where,
b>0 and b is not equal to 1.
x is any real number.
If the variable is negative, the function is undefined for -1 < x < 1.
Here,
“x” is a variable
“b” is a constant, which is the base of the function.
and a is also constant.
According to the given question
We have an exponential function
[tex]p(t) = ab^{t} ...(i)[/tex]
And from the given graph, the two points (0, 5) and (1, 10). So these points must satisfy the exponential function (i)
Substitute t = 0 and p(t) = 5 in (i)
⇒[tex]5 = a[/tex] or a = 5 ( because, [tex]b^{0} = 1[/tex] )
Again, substitute a = 5, t = 1 and p(t) = 10 in exponential function [tex]p(t) = ab^{t}[/tex]
⇒ 10 = 5[tex]b^{1}[/tex]
⇒ b = 2
Therefore, the exponential function p(t) is given by
[tex]p(t) = 5(2^{t})[/tex]

Which method should we use to calculate the area for this triangle? What is the area of this triangle calculated to the nearest hundredth of a square unit?
Answer:
34.98 square units.
Step-by-step explanation:
It is given that DEF is a triangle, EF=10, DF=7 and DE=12.
Information of sides of triangle is relevant to calculating area.
We should use Heron's formula.
According to Heron's formula, the area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where,
[tex]s=\dfrac{a+b+c}{2}[/tex]
For triangle DEF, let a=10, b=7 and c=12.
Now,
[tex]s=\dfrac{10+7+12}{2}=\dfrac{29}{2}=14.5[/tex]
Area of triangle is
[tex]A=\sqrt{14.5(14.5-10)(14.5-7)(14.5-12)}[/tex]
[tex]A=\sqrt{14.5(4.5)(7.5)(2.5)}[/tex]
[tex]A=\sqrt{1223.4375}[/tex]

Assume that all triangles have interior angles less than 90°.A surveyor sights on a survey marker that is 132.3m distant. She needed to turn her transit (her survey instrument) 75° to sight on a second survey marker. She knows that from the second marker, the angle between the line of site from her own position and the first marker is 68°. How far is she from the second marker?
Answer:
85.9 m
Step-by-step explanation:
The law of sines can help figure this.
The remaining angle in the triangle is ...
180° -75° -68° = 37°
This is the angle opposite the leg from the surveyor to the second marker. Referencing the attachment, we have ...
b/sin(B) = c/sin(C)
b = sin(B)·c/sin(C) = 132.3·sin(37°)/sin(68°) ≈ 85.873 . . . meters
The surveyor is about 85.9 meters from the second marker.
