Answer:
x = 30°
Step-by-step explanation:
As we can see it is right angled triangle so
2x + x + 90° = 180° (Sum of angels of triangle )
3x + 90° = 180°
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°
Hope it will help :)❤

4. The cube root parent function is reflected across the x-axis, vertically stretched by a factor of 3 then
translated 8 units down. Write an equation that could represent this function.
Answers
Using translation concepts, it is found that the equation is given by:
[tex]y = -3\sqrt[3]{x} - 8[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The parent cube root function is given by:
[tex]y = \sqrt[3]{x}[/tex]
It was reflected across the x-axis, that is, multiplied by -1, hence:
[tex]y = -\sqrt[3]{x}[/tex]
It was vertically stretched by a factor of 3, hence:
[tex]y = -3\sqrt[3]{x}[/tex]
Then, it was translated 8 units down, hence:
[tex]y = -3\sqrt[3]{x} - 8[/tex]

Answer:
The answer is 149
Step-by-step explanation:
So 2 oranges added up is 56 which is basically
x+x=56
2x=56
56/2=28
Each orange is worth 28
The 2 triangles multiplied are 81 which is
x*x=81
x^2=81
√81=9
Each watermelon Is worth 9
The 3 stars added up are
x+x+x=15
3x=15
15/3=5
Each star is worth 5
So the final equation if you plug in what we know
9+28*5
So orders of operations, (Parenthesis, exponents, etc.)
So multiplication is first
28*5=140
And add
140+9=149
So final answer 149

Determine the 8th term in the sequence defined by: A_n = 3 * 2^n-1
Answers
Answer:
384 but see below.
Step-by-step explanation:
Remark
A_n = 3*2^(n - 1) I will assume that's what you mean. I'll give the answer for A_n = 3*2^n - 1 as well.
Solution
n = 8
A_n = 3 *2^(8 - 1)
A_8 = 3*2^7
A_8 = 3* 128
A_8 = 384
If you mean A_n = 3*2^n - 1
Then you would get
A_n =3 * 2^8 - 1
A_8 = 3 * 256 - 1
A_8 = 768 - 1
A_8 = 767

Kathy needs money for a trip to Europe if she has US$300 in the bank but wants to withdraw half of it In British pounds and half of it into euros how many more euros and times with Havasu 1 pound equals 1.6 for US deep and one euro equals 1.3 to USD and round to the nearest whole
Answers
Answer: She has 21.63 more euros than pounds and has 1.23 times more euros than pounds.
Step-by-step explanation:
She has US$300, and she will withdraw half of it on pounds, and half of it in euros.
(half of US$300 is US$150)
We know that:
1 pound = US$1.6
(1 pound/US$1.6) = 1
Then US$150 = US$150*(1 pound/US$1.6) = (150/1.6) pounds = 93.75 pounds.
And we also know that:
1 euro = US$ 1.3
then:
(1 euro/US$ 1.3) = 1
This means that:
US$150 = US$150*(1 euro/US$ 1.3) = (150/1.3) euros = 115.38 euros.
This means that:
115.38 - 93.75 = 21.63
This means that she has 21.63 more euros than pounds.
and:
115.38/93.75 = 1.23
She has 1.23 times more euros than pounds.

Step 2: Solve for x
Divide 20 on both sides: x + 9 = 7Subtract 9 on both sides: x = -2Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 20(-2 + 9) = 140(Parenthesis) Add: 20(7) = 140Multiply: 140 = 140Here we see that 140 does indeed equal 140.

OAB is the sector of a circle, centre 0, with radius 8 cm and sector angle 30°.
BC is perpendicular to OA.
Calculate the area of the region shaded on the diagram.
Answers
Answer:
[tex]2.9 cm^2[/tex]
Step-by-step explanation:
Given,
Angle of sector = 30°
Radius of circle, r = 8 cm
Area of the shaded region, A =?
The diagram is attached below.
Now,
Area of shaded region = Area of sector - Area of triangle
Area of triangle = [tex]\frac{1}{2}\times base \times height[/tex]
We know that,
[tex]\sin \theta = \dfrac{P}{H}[/tex]
[tex]\sin 30^\circ= \dfrac{P}{8}[/tex]
[tex]P = \dfrac{8}{2}[/tex]
[tex]P = 4\ cm[/tex]
And
[tex]\cos \theta =\dfrac{B}{H}[/tex]
[tex]\cos 30^\circ = \dfrac{B}{8}[/tex]
[tex]B = \dfrac{8\times \sqrt{3}}{2}[/tex]
[tex]B = 4\sqrt 3[/tex]
Area of sector = [tex]\dfrac{\theta}{360^\circ}\times \pi r^2[/tex]
Area of sector = [tex]\dfrac{30^\circ}{360^\circ}\times \pi \times 8^2[/tex]
= 16.75 cm^2
Area of triangle = [tex]\dfrac{1}{2} \times 4\sqrt 3 \times 4[/tex]
= 13.85 cm^2
Area of shaded region = 16.75 - 13.85
= [tex]2.9 cm^2[/tex]

Answers
Answer:

Step-by-step explanation:
In a parallelogram, opposite angles are equal.
So that means
2(3x - 4) = x + 37
6x - 8 = x + 37
5x = 45
x = 9
Answer:
x+37=2(3x-4) opposite angle of the parallelogram are equal
x+37=6x-8
37+8=6x-x
45=5x
x=9
the measure of QRS=2(3×9-4)=46
A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at most 24 square feet. (These are rules of the local fire department.) Write an inequality that describes the possible lengths (in feet) of the stage.
Answers
Answer: Length ≥ 6 feet
Step-by-step explanation:
The area of a rectangle= length × width
In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.
The inequality that describes the possible lengths (in feet) of the stage would be:
Length × Width ≥ 24
Length × 4 ≥ 24
Length ≥ 24/4
Length ≥ 6
Therefore, the length must be at most 6 feet.

Answers
Answer: x = 2 and y = 5
Step-by-step explanation:
y = 2x + 1
3x + y = 11
Substitute
3x + (2x + 1) = 11
5x + 1 = 11
Subtract both sides by 1
5x = 10
Divide both sides by 5
x = 2
y = 2x + 1
Substitute
y = 2 (2) + 1
y = 4 + 1
y = 5

Answers
Answer:
[tex]V=2078.16\ cm^3[/tex]
Step-by-step explanation:
A rectangular sheet of dimensions 33 cm x 24 cm is rolled into a cylinder so that the smaller side becomes the height of the cylinder.
h = 24 cm
and the circumference of the cylinder, C = 33 cm
[tex]2\pi r=33\\\\r=\dfrac{33}{2\pi}\\\\r=5.25\ cm[/tex]
We need to find the volume of the cylinder so formed. The formula for the cylinder is given by :
[tex]V=\pi r^2h\\\\=\pi \times 5.25^2\times 24\\\\=2078.16\ cm^3[/tex]
So, the volume of the cylinder so formed is [tex]2078.16\ cm^3[/tex].
