Find the domain and range of the relation. {(−7,−18),(−23,21),(4,13),(−17,22),(2,−10)}
Answer: Domain = all x values and Range = all y values
Step-by-step explanation:
The domain of a function is all the allowed x values that make the function true. Luckily you were already given the domain. Its all the x values.
The range of a function is pretty much all the allowed y values of a function. Or, what y values the function can be equal to. So that's just all the y values
When listing the domain and range, you generally want to do it from least to greatest and you do not want to repeat any values
Answer:
D:{ -23,-17,-7,2,4}
R:{-18,-10,13,21,22}
Step-by-step explanation:
The domain is the input
D:{ -7,-23,4,-17,2}
We normally put them in numerical order
D:{ -23,-17,-7,2,4}
The range is the output
R:{-18,21,13,22,-10}
We normally put them in numerical order
R:{-18,-10,13,21,22}

Step-by-step explanation:
complementary angles are angles that added equal to an angle of 90 degrees and it says they are not congruent so the two angles are diferent
the given statement "Two complementary angles are not congruent" is not true. The counter-example is 45°+45°=90°.
The given statement is "Two complementary angles are not congruent."
What are complementary angles?Two angles are Complementary when they add up to 90°.
Now, if we add 45°+45°=90°
Therefore, the given statement "Two complementary angles are not congruent" is not true. The counter-example is 45°+45°=90°.

Use the given figure to find the length of x.
Answer:
x = 18
Step-by-step explanation:
This problem can be solved using concept of Pythagoras theorem.
Pythagoras theorem states that in a right angled triangle, if "a" and "b" are sides containing the right angle and h is hypotenuse then the relation between them is [tex]a^2 + b^2 = h^2[/tex]
_________________________________________
Given in the problem
a = 24
b = x
h = x+12
applying Pythagoras theorem
[tex]24^2 + x^2 = (x+12)^2\\=> 576 + x^2 = x^2 + 24x + 144\\=>576 = x^2 + 24x + 144 - x^2\\=> 576 = 24x + 144 \\=> 576 - 144= 24x\\=> 432 = 24x\\=> x = 432/24 = 18[/tex]
for (x+12)^2 we have used formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex]
Thus, value of x is 18.

The solution of the equation 10 - (x +2) = 7x is -
5
-2
0
1
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
We have the equation
[tex]10-(x+2)=7x[/tex]
The first thing we need to do is distribute the negative throughout the parenthesis
[tex]10-x-2=7x[/tex]
Now, we can combine like terms
[tex]8-x=7x[/tex]
Now we can add x to each side
[tex]8x=8[/tex]
And lastly, we can divide each side by 8
[tex]x=1[/tex]
Our last step is to check our answer
[tex]10-(1+2)=7(1)\\\\10-(3)=7\\\\7=7[/tex]
Answer:
1
Step-by-step explanation:
1) 10-x-2=7x
2) -x + 8 = 7x
3) 8x=8
4) x=1
A man measured his height and found 5.7 feet. However, after he carefully measured his height a second time, he found his real height to be 5 feet.What is the percent error the man made the first time he measured his height?
Answer:
percentage error = 12.28%
Step-by-step explanation:
5 x 0.14 = 0.7
5 x 1.14 = 5.7
as increase is not the same as error decrease.
We use the same numbers 12.28% = 0.1228.
5.7 x 0.1228 = 0.69996 = 12.28%
5.7 - 0.69996 = 5.00004 foot. As decrease.
And find it is correct.
His error therefore was 12.28% out.
As we work the first numbers 5.7 and can only x by a number to see 5ft
We take 5.7 x 0.1228 and find 0.69996 when taken from 5.7 ft. is unmistakably 5 foot. (5.00004) ft.
Answer:
14%
Step-by-step explanation:
percent error = (experimental measure - real measure)/(real measure) * 100%
percent error = (5.7 ft - 5 ft)/(5 ft) * 100%
percent error = (0.7 ft)/(5 ft) * 100%
percent error = 0.14 * 100%
percent error = 14%
Terrell wrote that 5-4.2=8. Which statement about this answer is true?
Answer:
No.
Step-by-step explanation:
No. 5 - 4.2 = 0.8
Answer: 8 is wrong because a number gets smaller, not larger, when you take 4.2 from it.
Step-by-step explanation: I had this on my Imagine Math. The reason why this is wrong is because 5 – 4.2 doesn't not equal 8!Estimation might help. 5 doesn't need to be rounded. 4.2 is rounded to 4...5-4 = 1The Actual answer is actually 0.8.I hope this helps :)
Lachlan invested $4300 over 5 years at 4.6% p.a., compounded every 6 months. Find the total value of his investment.
Answer:
[tex]\fbox{\begin{minipage}{13em}approximately 5397.9 dollar\end{minipage}}[/tex]
Step-by-step explanation:
Given:
Lachlan invested $4300 over 5 years at 4.6% p.a., compounded every 6 months.
Solve for:
Total value of his investment.
Step 1: Define the formula to calculate the total value of Lachlan's investment
Total value = Principal x (1 + rate/2)^(Year x 2)
(the rate is divided by 2 and the year is multiplied by 2 because this is compounded semi-annual, not compounded annual)
Step 2: Perform the calculation:
With Principal = 4300$, Rate = 4.6% =4.6/100 = 0.046, Year = 5
=> Total value = 4300 x (1 + 0.046/2)^(5 x 2) ≈ 5397.9$
Hope this helps!

Select all true statements
Answer:
f(x) has a larger growth rate
f(x) is always greater than g(x)
Step-by-step explanation:
f(x) = 2/5 x
g(x) = -2x
the slope of f(x) when graphed is 2/5 x, which is a positive value making it a larger growth rate than g(x) and it also will always be greater since the value of f(x) is positive
therefore the correct true statements are:
f(x) has a larger growth rate, and f(x) is always greater than g(x)
options 1 and 3
Step-by-step explanation:
option 1 is correct because f (x) is positive hence making it greater than g(x) which is negative.

Answer:
15 dogs
12 cats
Step-by-step explanation:
Let's call the number of cats c, and the number of dogs d.
4d=5c
c+d=27
4c+4d=108
4c+5c=108
9c=108
c=12
d=27-12=15
Hope this helps!
Answer:
15 dogs and 12 cats
Step-by-step explanation:
You can draw out 27 lines or dots or smth. Then cross off 4. and then keep going. But for every four you cross off, underline or highlight 5. The four represent the cats and the 5 represent the dogs. By the end you should get 15 dogs and 12 cats. Another way you can do this is by mulitplying both the numbers by the same number until they equal 27.

Given: cosθ= -4/5 , sin x = -12/13 , θ is in the third quadrant, and x is in the fourth quadrant; evaluate tan (θ +x) and sin (θ +x))
Answer:
tan (θ+x)= -33/56
sin (θ+x)=33/65
Step-by-step explanation:
cosθ= -4/5 , sin x = -12/13
cosθ= -4/5; θ is in the third quadrant=> sinθ=-√(1-cos² θ)
sinθ=- √(1-16/25)=- √(9/25)=-3/5
sinx= -12/13; x is in the fourth quadrant=> cosx=+√(1-sin²x)
cosx=√(1-144/169)= √(25/169)=5/13
tgθ= sinθ/cosθ=(-3/5)/(-4/5)=3/4
tgx= sinx/cosx=(-12/13)/(5/13)= -12/5
tan (θ+x)=(tgθ+tgx)/(1-tgθ*tgx)
tan (θ+x)=(3/4-12/5)/(1+3/4*12/5)=(-33/20)/56/20)= -33/56
sin (θ+x)=sinθcosx+coxθsinx=-3/5 *5/13 +-4/5 * (-12/13)=-15/65+48/65=33/65

A shirt that originally cost $38.00 is on sale for 30% off. What is the sale price of the shirt?
1.
$11.40
2.
$26.60
3.
$29.23
$49.40 this is due today pls help.
_________________________________
Solution,
Marked price (MP)=$ 38.00
Discount%=30%
Sale price (SP)=?
Now,
Discount amount= discount% of MP
=30%of 38
=$ 11.4
Again,
Sale price(SP)=MP-Discount
= 38-11.4
=$26.60
The right answer is $ 26.60
Hope it helps...
Good luck on your assignment
_______________________________
Answer:
$26.60Step-by-step explanation:
[tex]orginal \: \: \: \: price = 38.00[/tex]
[tex]discount \\ percentage= 30\%[/tex]
First we have to find the discount.
[tex]discount = 38 .00\times \frac{30}{100} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 11.40[/tex]
Now let's find the sales price of the shirt.
[tex]sales \: \: \: price \\ =original \: \: \: \: price - \: discount \\ = 38.00 - 11.40 \\ = 26.6 0\\ [/tex]
