Which interval notation accurately represents the domain?
(–∞, 7) U (7, ∞)
(–∞, 5) U (5, ∞)
(–∞, 0) U (0, ∞)
(–∞, 10) U (10, ∞)
The domain represents interval notation is (–∞, 7) U (7, ∞) which is the correct answer would be an option (A)
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
For all other x-values, the graph appears to be defined. Thus, with the exception of x = 7, all real numbers should fall under the function's domain. This is what that would look like in interval notation:
It is possible to write the interval (–∞, ∞). as the set of all real numbers. Keep in mind that infinity∞ or -∞ is not a real number. Both ends are shown to be excluded from the interval by the rounded brackets.
All real numbers less than but not equal to 7 are contained in the set (-∞,7). (both ends are excluded.) The collection of every real number greater than but not equal to is.
All real numbers less than and higher than are combined to form the set of all real numbers that are not equal to 7. The union operator joins two intervals together.
Hence, the domain represents interval notation is (–∞, 7) U (7, ∞)

#SPJ2
find the missing angle
Answer:
56.44
Step-by-step explanation:
The sine of an angle is the length of the opposite side divided by the length of the hypotenuse, which in this case is 40/48=5/6. Therefore, that angle is the arcsin of this, or approximately 56.44 degrees, or answer choice C. Hope this helps!

Answer:
2x(3x + 2)
Step-by-step explanation:
Answer
102
Step-by-step explanation:
X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,
equations:
8+3=11
11+16=27
21/1=27
27/4= 6.75
6 x 3= 27
27 + 72 + 3= 102
Then go back to the beginning and do 1/4. If this confuses let me fix it.
now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)
20 POINTS!! Let logb A = 3; log, C = 2; log, D= 5
What is the value of logb(a5c2/d6)?
Answer:
-11
Step-by-step explanation:
logb ( a^5 c^2 / d^6)
Splitting these into log (xy/z) = log x + log y - logz
logb ( a^5) +logb ( c^2) - logb( d^6)
We also know that log x^y = y log x
5logb ( a) +2logb ( c) - 6 logb( d)
Given logb ( a)=3 logb ( c) =2 logb( d)=5

Answer:
B
Step-by-step explanation:
-4<= 2t <2
-4/2<= t <2/2
-2<= t <1
(Its touches -2 but doesnt touch 1)
Answer:
Firstly you have to divide by 2 to get 't' so -4/2=-2
2/2=1
so the simplified inequality= -2<t<1

Answer:
x = 45 degree as it is an alternate angle we use 135 degree to prove supplementary angles across the straight line add up to 180 degree.
Therefore we prove 180-135 = 45 degree and say all angles on straight line add up to 180 degree, and recognize x is an alternate angle as the arrow straight lines are parallel and create precise alternate lines from which we can prove multiple supplementary and alternate angles.
Supplementary can be either angle will always be supplementary from either 45 degree angle matched with any 135 degree as they don't have to be together to be supplementary they only have to equal 180 degree to be a supplementary angle.

What is the equation of the line that is perpendicular to the
given line and has an x-intercept of 6?
y=-3x+8
O y=-3x + 6
O y=-x-8
O y=x-6
Answer:
y=x-6
Step-by-step explanation:
The x-intercept is found replacing y = 0, as follows:
Function: y = -3x + 8
x-intercept:
0 = -3x + 8
3x = 8
x = 8/3
Function: y = -3x + 6
x-intercept:
0 = -3x + 6
3x = 6
x = 6/3 = 2
Function: y = -x - 8
x-intercept:
0 = -x - 8
x = -8
Function: y = x - 6
x-intercept:
0 = x - 6
x = 6
The last option is the only one in which x-intercept is x = 6.

using SOH CAH TOA, solve for x.
Answer:
x=10.93 or 10.9
Step-by-step explanation:
To find x we use sin
sin(40) = 0.6427876097 then * 17
= 10.9273
= 11
We can check and plug in answer as inverse to find other side
11/sin (40degree) x (90 degree) = 17.11
If we plug in the original 10.9273 we actually find 17
So we should show the correct amount 10.9273 and if rounding try 10.93
10.93/sin (40 degree) x sin (90 degree) = 17.00

x =
a.) 4
b.) 9
c.) 16
Answer:
x =16
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos 60 = 8/x
Switch the x and the cos 60
x = 8/cos 60
x =8 / (1/2)
x =16

Answer: y - 2 = 3/2(x + 1)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1). Where m is the slope. so you can just fill in:
y - (2) = 3/2(x - (-1))
y - 2 = 3/2(x + 1)
z2 (z squared) when z = 0.7 help us out
Answer:
0.49
Step-by-step explanation:
0.7^2 is the same as 0.7*0.7. You just have to times them together!
Hope this helps!
The solution is z^2= 0.49.
What is Square root?A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.
For example, 4 and −4 are square roots of 16, because 4² = ² = 16.
here, we have.
z^2=z*z
when z = 0.7
z^2= 0.7*0.7
=0.49
0.7^2 is the same as 0.7*0.7.
Hence, the solution is z^2= 0.49.

in a triangle, what is the 3rd angle measure if the other two angles are each 60
Pls Need Help!
Triangle Q S R. Angle Q is 98 degrees and angle R is 37.6 degrees. Triangle T U V. Angle U is 98 degrees and angle V is 37.6 degrees.
Which statement is not true about these triangles?
A. ∠Q ≅ ∠T based on the third angle theorem.
B. ∠S corresponds to ∠V.
C. ∆QRS ~ ∆TVU based on the angle-angle criterion.
D. ∆RQS ~ ∆VTU based on the angle-angle criterion.
Answer: ∠S corresponds to ∠V.
The solution is Option B.
The measure of angle ∠S corresponds to ∠V
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the first triangle be ΔQSR
Let the second triangle be ΔTUV
Now , the measure of ∠Q = 98°
The measure of ∠R = 37.6°
The measure of ∠U = 98°
The measure of ∠V = 37.6°
So , the measure of the third side of the triangles is
The measure of ∠S = measure of ∠T = 180 - ( 98 + 37.6 )
The measure of ∠S = measure of ∠T = 44.4°
And , ∆QRS ~ ∆TVU based on the angle-angle criterion
So , ∠Q ≅ ∠T based on the third angle theorem
And , ∆RQS ~ ∆VTU based on the angle-angle criterion
Hence , the false statement is ∠S corresponds to ∠V.
