2k+8=0 Can someone help explain how to solves this please?
Answer:
2k + 8 = 0
2k + 8 - 8 = 0 - 8
2k = - 8
2k/2 = - 8/2
k = - 4
Step-by-step explanation:
you gotta put the 8 on the other side by subtracting and the divide both sides to get k
Answer:
k = -4
Step-by-step explanation:
2k + 8 = 0
Subtract 8 from both sides.
2k = -8
Divide both sides by 2.
k = -4
Find the measure of angle a.
a
50°
Answer:
the measure of angle is m(<a)=40
Step-by-step explanation:
the intirior angles of all triangles add up to 180
with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.
180
90
-50
---------
=40 degreese
hoped this helped.
Step-by-step explanation:
a+50+90=180°(being sum of angle of right angled▲)
or, a+140= 180°
or, a=180°_ 140°
Therefore, a=40°

3(x+2) = 3x + 6 is an example of which property?
Answer:
Distributivity.
Step-by-step explanation:
A container holds 5 1/3 pints of water. A bucket holds 1 1/4 times as much water than the other container how many pints of water does the bucket hold
The quantity of water that the bucket can hold given the quantity of water the container can hold is 6 2/3 pints.
How much water can the bucket hold?In order to determine the quantity of water the bucket can hold, we have to multiply the pints the container can hold by 11/4
5 1/3 x 1 1/4
Convert the mixed fractions to improper fractions
16/3 x 5/4 = 20/3 = 6 2/3 pints

Write the slope-intercept form of the given line. Include your work in your final answer.
Answer:
y=1x+-1
Step-by-step explanation:
y=mx+b
m=slope which is 1/1 because it is rise over run (rising 1, running 1)
b=y-intercept form which is -1 because that is where the line meets the y axis
Find the outer perimeter of this figure.
Round your answer to the nearest
hundredth. Use 3.14 to approximate.
Answer:
P = 28.66 ft
Step-by-step explanation:
So perimeter of half circle
= 2π × 6/2
= 2π × 4/2
= 8π ft/2
= 4 π
Total Perimeter = 6 ft + 8π/2 ft + 10 ft +
= 6 ft + 4 π ft + 10 ft

Total Perimeter = 28.66 ft
PLEASE MARK ME AS BRAINLIEST AND HAVE A NICE DAY
Answer:
28.56
Step-by-step explanation:
The sides of the triangles are already given, so that will be 16. The diameter of the circle is given to be 8, so the radius will be half of it, 4. The circumference of a circle 2πr, so the circumference is 8π. we need to divide this by two because it is a semicircle, so the circumference of the semicircle is 4π. The answer should be 16+4π, and we can substitute in 3.14 for π to get 12.56+16=28.56

Based on the data provided and using logical reasoning, Mr Smith has seven children, four sons and three daughters.
What is logical reasoning?Logical reasoning means using critical thinking skills to provide solutions to given problems.
The number of children Mr. Smith has can be determined by using the skill of logical reasoning.
Mr Smith has at least one son.He also has at least two daughters.Assuming that son has two brothers, then he also has two sisters.
Each sister has one sister and three brothers.
This scenario does not satisfy the conditions.
Assuming that son has three brothers, then he also has three sisters.
Each sister has two sisters and four brothers.
Therefore, Mr Smith has seven children, four sons and three daughters.

Answer:
Depends on what sequence it is. For geometric it's 7/5 and for arithmetic - 2
Step-by-step explanation:
For n = 3:
a, = 1*2*3 - 1 = 5
For n = 4:
a, = 8 - 1 = 7
These are the terms for n = 3 and n = 4 but the thing is, this could be both geometric sequence and arithmetic sequence, since you didn't specify, here are the possible answers:
For geometric sequence, the rate of change is equal to An / An-1 therefore:
r = 7 /5
For arithmetic sequence, it's equal to A2 - A1 = 7 - 5 = 2
The classical approach to probability requires that the outcomes are _______.
Answer:
equally likely
Step-by-step explanation:
The classical approach to probability requires that the outcomes are equally likely.
Equally likely means the chance or possibility of selection in the sample is equal for them. None is prioritized over the other, all has the equal chance of being selected in the sample.
Given that we are using the classical approach to probability which is based on an assumption that for any procedure having random set of possible outcomes, the possibility of each outcome is equal.
Thus, the classical approach to probability requires that the outcomes are equally likely.

An electronic salesman wants to earn $4,000 in November. He receives a base salary of $2000 per month as well as a 10% commission for all sales in that month. How much merchandise will he have to sell to earn the amount of money he wants
20000
Based on the given conditions, formulate:
[tex](4000-2000)\div10\ percent[/tex]
Calculate
[tex]\frac{4000-2000}{0.1}[/tex]
Calculate the sum or difference
[tex]\frac{2000}{0.1}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]\frac{20000}{1}[/tex]
Any fraction with a denominator of 1 is equal to its numerator
[tex]20000[/tex]
I hope this helps you
:)
Step-by-step explanation:
his salary =$2000
his commission should be (to make a total of $4000/month )=$4000-$2000 =$2000
let he should sell x amount over $7000 to get $2000 commission
So, 7% of x = 2000
7x/100 = 2000
x= (2000*100)/7 =28571.43 approx
As he will get commission on sales over $ 7000,so his should sell in a month
=$7000+$28571.43

y = sec(x) has a range of f(x) ≤ -1 and f(x) ≥ 1
Thus does not include zero in the range scale.
Extra's:
y = cos(x) has a range of -1 ≤ f(x) ≤ 1
y = cot(x) has infinity range
y = tan(x) has infinity range.
Answer:
sec x
Step-by-step explanation:
Let's set each function equal to zero to see if they have zero in their function.
If there is no solution, then we no solution of zero.
[tex] \cos(x) = 0[/tex]
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution of zero.
[tex] \cot(x) = 0[/tex]
[tex] \frac{ \cos(x) }{ \sin(x) } = 0[/tex]
There answer here is
[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]
So there is a solution. of zero here
If cot x=0, has a solution of zero, then tan x does as well. Since we can use
[tex] \frac{ \sin(x) }{ \cos(x) } = \tan(x) [/tex]
[tex] \frac{ \sin(x) }{ \cos(x) } = 0[/tex]
The answer here will be
[tex]0 + 2\pi(n)[/tex]
So that leaves sec x.
Proof:
[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]
1 divided by any number won't equal zero, so the solution will never be 0.

How do you do this question?
Problem 1
You are correct. The answer is choice C.A sequence is just a list of numbers where the order matters. Something like (1,2,3,4,5) is different from (3,1,2,5,4)
A series is where you add up that list of numbers to get a single value. For instance, the sum of the list (1,2,3) is 1+2+3 = 6. This is basically a partial sum when talking about infinite sequences because the next partial sum would be 1+2+3+4 = 10 and the next partial sum would be 1+2+3+4+5 = 15, and so on.
=======================================================
Problem 2
Answer: Choice AWhy is this? Each time we get a partial sum, we're basically forming a new sequence. We're forming a sequence of sums. Going back to the example in problem 1, we had the partial sums (6,10,15). If we keep this process going, we'll have the list of partial sums grow forever and not approach some finite value. Therefore, this series diverges.
If the sums were to slowly get closer to some fixed value, then we would say the series converges.
