What is the slope of line JK?
Answer:
perp. just switch from -2/5 to positive 5/2
Step-by-step explanation:
Answer:
m2 =5/2
Step-by-step explanation:
m1=-1/m2
m2=-1/m1
y=-2/5x-10
m1=-2/5
m2= -1/-2/5
m2=5/2
y=5/2x-10 ⊥ y=-2/5x-10
Suppose that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find the average cost per radio of producing the first 40 radios.
Answer:
24radios
Step-by-step explanation:
Given that the dollar cost of producing x ratios is c(x)=800+40x-0.2x^2. Find
Average cost is expressed as dC(x)/dx
dC(x)/dx = 40-0.4x
C'(x) = 40 - 0.4x
If x = 40
C'(40) = 40 - 0.4(40)
C'(40) = 40 - 16
C'(40) = 24
Hence the average cost per radio of producing the first 40 radios is 24radios

Given,
[tex]3x - 2y = 5[/tex]
[tex]xy = - 2[/tex]
Now,
[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ [/tex]
Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²
[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]
✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy
Now,
xy = - 2
So, 12xy = 12 × - 2 = - 24
•°• 24 + 12xy
= 24 + (-24)
= 24 - 24
= 0
⎆ The value of 9x² + 4y² - 1 is 0.ʰᵒᵖᵉ ⁱᵗ ʰᵉˡᵖˢ

Whats the Angle for A,B, and C? Ive been stuck on this problem for a while. It would be great if you helped
Answer:
b=57° (vertically opposite angles)
Step-by-step explanation:
57°+a+b+c=360° (angles around a point)
57°+57°+a+c=360°
114°+a+c=360°
a+c=360°-114°=246°
a=c (vertically opposite angles)
therefore 2a=246°
a=123°
b=123°

Answer:
h = 9.6 ft
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
h² + 7.2² = 12² ( h is the height of the building )
h² + 51.84 = 144 ( subtract 51.84 from both sides )
h² = 92.16 ( take the square root of both sides )
h = [tex]\sqrt{92.16}[/tex] = 9.6 ft
in a class of 32 students
Answer:
1.48 m
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Then the sum for the 14 boys is
[tex]\frac{sum}{14}[/tex] = 1.56 ( multiply both sides by 14 )
sum = 21.84 m
The sum for the class of 32 is
[tex]\frac{sum}{32}[/tex] = 1.515 ( multiply both sides by 32 )
sum = 48.48 m
Thus the sum for the 18 girls is
sum = 48.48 - 21.84 = 26.64 m
Then mean height of girls is
mean = [tex]\frac{26.64}{18}[/tex] = 1.48 m

SOMEONE PLS HELP ME FIND X
Answer:
step one you look at the question until you find the ex cuz it says 125 degrees and 125 degrees 2x
Answer:
x = 50
Step-by-step explanation:
The sum of all entire angles in this, esentially a pentagon, add up to 540
To find x, use the following
540 = 125 + 125 + 90 + 2x + 2x
540 - 125 - 125 -90 = 4x
200 = 4x
200 / 4 = x
50 = x

Answer:
x = 5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{5}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by 5 to clear the fraction )
x = 5[tex]\sqrt{3}[/tex]
What is the volume of a cone that has a height of 10 feet and a base with a surface area(B) of 9 square feet?
Answer:
30 cubic feet
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Height of cone (h) = 10 feet
Base surface area = π[tex]r^{2}[/tex] = 9 sq. feet
So we can calculate the volume of cone by using following formula,
volume of cone = (1/3)π[tex]r^{2}[/tex]h
By putting the value in the formula, we get
Volume of cone = (1/3) 9 × 10
= 3 × 10
= 30 cubic feet
Given that (1, 0, 1) is a solution to a system of three linear equations, which of the following is true about the system?
The system can be either inconsistent or consistent.
The system can be either independent or dependent.
The system can only be independent and consistent.
The system can only be dependent and inconsistent.
===========================================================
Explanation:
Let's go through the answer choices
A) This isn't possible. Either a system is consistent or inconsistent. It cannot be both at the same time. The term "inconsistent" literally means "not consistent". It's like saying a cup is empty and full at the same time. We can rule out choice A.B) This is similar to choice A and we cannot have a system be both independent and dependent. Either a system is independent or dependent, but not both. Independence means that the two equations are not tied together, while dependent equations are some multiple of each other. We can rule out choice B.C) We'll get back to this laterD) The independence/dependence status is unknown without the actual equations present. However, we know 100% that this system is not inconsistent. This is because the system has at least one solution. Inconsistent systems do not have any solutions at all (eg: parallel lines that never cross). We can rule out choice D because of this.Going back to choice C, again we don't have enough info to determine if the system is independent or dependent, but we at least know it's consistent. Consistent systems have one or more solutions. So part of choice C can be confirmed. It being the only thing left means that it has to be the final answer.
If it were me as the teacher, I'd cross out the "independent" part of choice C and simply say the system is consistent.
Answer:
Above that (1, 0, 1) is a solution to a system of three linear equations, The system can only be independent and consistent. is true about the system.

Determine the equation of the circle graphed below
Answer:
[tex](x-1)^2+(y-6)^2=16[/tex]
Step-by-step explanation:
The equation of a circle is given by [tex](x-h)^2+(y-k)^2=r^2[/tex], where [tex](h,k)[/tex] is the center of the circle and [tex]r[/tex] is the radius of the circle.
From the diagram, we can find the following:
the radius of the circle is 4 the center of the circle is located at (1,6)Thus, we have:
[tex](x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}[/tex]
Answer:
(x-1)^2 + (y-6)^2 = 16
Step-by-step explanation:
center = (1,6)
radius = 4
equation of a circle (x-h)^2+(y-k)^2=r^2
(x-1)^2 + (y-6)^2 = 16
There is a box with red and green apples there are 60 apples in total determine the number of green apples if 40% of the apple are red
Answer:
36 green apples
Step-by-step explanation:
Number of red apples = percentage of red apples x total number of apples in the box
percentage of red apples = 100 - 40 = 60%
0.6 x 60 = 36
Triangle ABC is the image of triangle ABC after a translation of 2 units to the night and 3 units
up is triangle ABC congruent to triangle ABC?
Answer:
yes the triangle is congruent, because you did not use any transformations you on used translations.
but if you used transformations it would be similar not congruent
