Answer:
[tex]Dom_{f}=[-3,\infty)[/tex]
[tex]Range_{f}=(-\infty,-2][/tex]
Step-by-step explanation:
I understand the correct function is [tex]f(x)=-\sqrt{x+3} - 2[/tex]
Domain of f
[tex]x+3\geq 0\\x\geq -3[/tex]
Thus, [tex]Dom_{f}=[-3,\infty)[/tex]
Range of f
[tex]Range_{f}=(-\infty,-2][/tex]

A triangle has one angle that measures 19 degrees, one angle that measures 118 degrees, and one angle that measures 43 degrees.
What kind of triangle is it?
A. right triangle
B. obtuse triangle
C. acute triangle
D. equilateral triangle
Answer:
B. obtuse triangle
Step-by-step explanation:
Obtuse triangles are triangles with one obtuse angle and two acute angles. Define obtuse angles as angles over 90 degrees and acute angles as angles less than 90 degrees.
In this triangle:
118 degrees - obtuse angle
19 degrees - acute angle
43 degrees - acute angle
Thus, this triangle is an obtuse triangle.
someone please help or i’ll be failing geometry this year
Step-by-step explanation:
I don't know what constructions you were taught.
a "similar" triangle is a triangle with exactly the same angles as the other triangle, but the lengths of all sides are stretched or shortened by the same scaling factor f.
by saying 1:2 she means the second triangle should have sides with twice the lengths of the first triangle (f=2).
and the extra challenge - same basic thing. she allows you to pick one of the two triangles as reference. and then you need to draw a third triangle (again with the same angles) with the side lengths extended by the scaling factor f of 4/3.
I would draw the triangles right on top of each other with the same starting corner (let's call it A) for all 3.
we would get the triangles ABC, AMN and AXY.
the points B and C would be then halfway on AM and AN.
and M and N would then a bit before X and Y on AX and AY.
the beauty is, you only need to construct 2 sides of every new triangle down to the new endpoints. the third side is automatically scaled correctly, and you only need to connect these new endpoints.
let's assume you draw a triangle (just very simple) ABC with all side lengths being 3. so, AB=3, AC=3, BC=3.
now you draw AMN by extending AB and AC to a side length of 6 (f=2) creating M and N, and you connect M and N.
and then you can create the third triangle AXY by extending AM and AN by a factor of 4/3 to side lengths of 8 (4/3 × 6 = 8) creating new end points X and Y. and you connect X and Y.
and that is it. all 3 triangles are similar (the same angles), and all sides of a triangle have the same length ratio to the sides of the other triangle(s).
Find the missing side. Round to the nearest tenth.
Answer:
3
Step-by-step explanation:
if you put six beside the unknown side then you will see that x =3
Bern is flying a kite directly over his friend Frank. Bern lets out string which makes an angle of 28°
with the ground. If the kite is 175 feet above Frank, how far are Bern and Frank?
Help ASAP!!
orayt so 28 degree and 175 feet is about...the fox jumps into the lazy dog and say "c'mon barbie let's go party! ah ah ah yeah"....but i dont know the answer as well so thank you.
Answer:
Approximately [tex]329\; \rm ft[/tex], assuming that the ground between Bern and Frank is level.
Step-by-step explanation:
Refer to the diagram attached.
The kite is right above Frank. Therefore, the imaginary line segment (the dashed line segment in the diagram) would form a right angle with the ground under Frank. Bern, Frank, and the Kite would be the three vertices of a right triangle.
The question states that from the perspective of Bern, the angle of elevation of the kite is [tex]28^\circ[/tex]. In this right triangle, the side opposite to this angle would be the imaginary line segment between Frank and the kite over him. The question states that the length of this imaginary line segment is [tex]175\; \rm ft[/tex].
The question is asking for the length of the line segment between Bern and Frank. In the right triangle pictured in this diagram, that line segment would be the side adjacent to the [tex]28^\circ[/tex] angle.
The cotangent of [tex]28^\circ[/tex] would be the ratio between the length of these two sides:
[tex]\displaystyle \cot (28^\circ) = \frac{\text{adjacent}}{\text{opposite}}[/tex].
[tex]\begin{aligned}\text{adjacent} &= \text{opposite} \cdot \cot(28^\circ) \\ &= (175\; \rm ft) \cdot \cot(28^\circ) \approx 329\; \rm ft\end{aligned}[/tex].

6, 8, 11, 12, 2x – 8, 2x + 10, 35, 41, 42, 50
are in ascending order. If the median is 25,
find the value of x.
Ans: 12
Answer:
12
Step-by-step explanation:
(2x-8+2x+10)/2 = 25
(4x+2) = 2×25
4x+2 = 50
4x = 50-2
4x = 48
x = 48/4
x = 12
Answer:
x = 16.5 as the median in this term is 2x-8
and 2x-8 = 25
25+8=2x
33=2x
x=[tex]\frac{33}{2}[/tex]
= 16.5
Step-by-step explanation:
this answer says 12 which is false

If PR is 4, WQ is 8, and QR is 5, SP = ___ units
Answer:
From the attached graphic, we can see:
(SP + PR) * PR = (WQ + QR) * QR
SP * PR + PR^2 = WQ * QR + QR^2
4 SP + 4*4 = 8 * 5 + 25
4 SP + 16 = 65
4 SP = 49
SP = 49 / 4
SP = 12.25

Answer:
3 ft , 4 ft and 5 ft is a triangle.
Step-by-step explanation:
The first is not a triangle as 4 + 4 = 8 so triangle cant be drawn with these lengths.
Also third: 3 + 3 < 7 and last one 4 + 5 < 10 so neither are triangles.

Can u Put 9x + 3y = -9in slope intercept form ?
Answer:
y = - 3x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
9x + 3y = - 9 ( subtract 9x from both sides )
3y = - 9x - 9 ( divide terms by 3 )
y = - 3x - 3 ← in slope- intercept form
Determine the volume of the space in the tank that still needs to be filled with water if the water is ⅓ ft. Deep
Answer:
11 1/9 ft^3
Step-by-step explanation:
find the complete question in the attached image
volume of the tank = length x width x height
2 x 5 x 1 2/3
2 x 5 x 5/3 = 50/3 = 16 2/3 ft^3
If the tank is 1/3 filled with water, the volume that needs to be filled with water is 1 - 1/3 = 2/3
volume that needs to be filled with water = 2/3 x volume of the tank
2/3 x 50/3 = 11 1/9 ft^3
the variables y and x are related by the equation y=2/3 x. which graph shows this relationship
Answer:
H
Step-by-step explanation:
2/3 means a rise of 2 and a run of 3

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 4 large boxes and 8 small boxes has a total weight of 169 kilograms. A delivery of 2 large boxes and 3 small boxes has a total weight of 71 kilograms. How much does each type of box weigh?
Answer:
weight of large box=15.250 kgm
wight of box=13.500 kgm.
Step-by-step explanation:
let weight of large box=x kgm
and weight of small box=y kgm.
4x+8y=169
2x+3y=71
multiply by 2
4x+6y=142
subtract from first
2y=27
y=27/2=13.500 kgm
4x+8(27/2)=169
4x+108=169
4x=169-108
4x=61
x=61/4=15.250 kgm

Siera has 11.5 yards of yarn. She uses a certain amount for a project, leaving 5.25 yards of yarn. How much yarn did Siera use for her project?
Answer: 6.25
Step-by-step explanation: 11.5 minus the amount you're left with.
11.5 - 5.25 = 6.25
To fact check.
6.25 - 11.5 = 5.25

x = 3y
4x + 5y = 34
solve for x and y
Help help
Answer: y=2 and x=6
Step-by-step explanation:
x=3y
4x+5y=34
From equation ( 1) x=3y thus substituting in eqn(2)
4(3y)+5y=34
12y+5y=34
17y=34
y=34÷17=2
Thus y=2
Putting y=2 in eqn(1)
x=3y
x=3(2)
x=6
What is the expanded form of this number? 630.052 A(6×100)+(3×10)+(5×110)+(2×1/100) B (6×100)+(3×1)+(5×110)+(2×1/100) C (6×100)+(3×1)+(5×1100)+(2×1/1,000) D (6×100)+(3×10)+(5×1/100)+(2×1/1,000)
Answer:
Its D.
Step-by-step explanation:
The expanded form of this number 630.052 is (6×100)+(3×10)+(5×1/100)+(2×1/1,000). Option D is correct.
What is the definition of arithmetic operation?Arithmetic is a branch of mathematics that studies numbers and the many operations that may be applied to them. The four basic math operations are addition, subtraction, multiplication, and division.
The expanded form of this number 630.052 is solved by the BODMAS rule ;
630.052= (6×100)+(3×10)+(5×1/100)+(2×1/1,000)
630.052=6×100+3×10+5×0.01+2×0.001
630.052=600+30+0.05+0.002
630.052=630.052
The expanded form of this number 630.052 satisfy the option D.
Hence option D is correct.

The manager of a department store wants to know if any of the company's 281 employees would buy a reduced gym membership. The manager surveyed 70 randomly chosen employees, and 50 reported they would buy a reduced gym membership.
Answer: 201 employees
Step-by-step explanation:
Question wants to know the predicted number of employees from the total number that would buy a reduced gym membership.
Going by the number of employees from the sample of 70 that said they would prefer a reduced membership, one can estimate a predicted value for the number of employees from the total population of 281 that would want the same.
Find the percentage that would want a reduced membership from the sample:
= 50 / 70 * 100%
= 71.43%
Apply this to the total population:
= 71.43% * 281
= 200.7
= 201 employees
