NOTE: Angles not necessarily drawn to scale.
Answer:
x = 60°
Step-by-step explanation:
∠ CGE = ∠ FGD = 30° ( vertical angles )
∠ CGB = 90° , then
x + 30° = 90° ( subtract 30° from both sides )
x = 60°

Answer:
[tex]m\angle Y=30^{\circ}[/tex]
Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
Therefore, we have:
[tex]\cos Y=\frac{42\sqrt{3}}{84},\\Y=\arccos(\frac{42\sqrt{3}}{84})=\boxed{30^{\circ}}[/tex]

HELP PLEASEE
Answer:
[tex]x=2\sqrt3\ km[/tex]
Step-by-step explanation:
Given that,
The base of a triangle = 2 km
The perpendicular height of the triangle = [tex]2\sqrt{2} \ km[/tex]
We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :
[tex]x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km[/tex]
So, the value of x is equal to [tex]2\sqrt3\ km[/tex].
A cylinder has a height of 18 feet and a diameter of 38 feet. What is its volume? Use it %
3.14 and round your answer to the nearest hundredth
Answer: 20,403.72ft3
Step-by-step explanation:Volume formula for cylinder is = 2h
V=Volume
=pi=3.14
r=radius
h=height
Step 1: find the radius.
Diameter=38
so divide 38 by 2
=19
Step 2: Plug in and solve for Volume.
V=3.14x19^2x18
= V=1133.54x18
= V=20,403.72
Please Help I've tried like 30 times and I still get it wrong
Answer:
604.4 cm²
Step-by-step explanation:
Surface area of a cone = πr(r + √h² + r²)
π = 3.14
r = diameter/2 = 13.4 cm/2 = 6.7 cm
h = 21 cm
Surface area of a cone = πr(r + √h² + r²)
= 3.14 * 6.7(6.7 + √21² + 6.7²)
= 21.038(6.7 + √441 + 44.89)
= 21.038(6.7 + √485.89)
= 21.038(6.7 + 22.04)
= 21.028(28.74)
= 604.3 cm²
Surface area of a cone = 604.4 cm²

Please help me with this question??m
Answer:
75
Step-by-step explanation:
f(1) = 7
f(n) = 3f(n-1) + 3
So what you are trying to do here is find the recursive value (that's what it is called) for f(n). Computers love this sort of thing, but we humans have to do it slowly and carefully.
So let's try f(2)
That means that f(2) = 3*f(n-1) + 3
but if f(2) is used it means that you have to know f(2-1) which is just f(1) and we know that.
so f(2) = 3*f(1)+3
f(2) = 3*7 + 3
f(2) = 21 + 3
f(2) = 24
Now do it again. We now know F(2), so we should be able to find f(3)
f(3) = 3*f(3 - 1) + 3
f(3) = 3*f(2) + 3 We know that f(2) = 24
f(3) = 3* 24 + 3
f(3) = 72 + 3
f(3) = 75

Find the domain of the graphed function. A.x>=0 B. x is all real numbers. C.-9<=x<=5 D.0<=x<=10
The domain of the function represented by the graph is x ≥ 0
How to determine the domain of the graph?The function is represented by the graph of the function
From the given graph, we have the following observations
The graph is a trigonometric graphThe x values of the graph starts from 0 and increases towards the positive axisThis means that the function has a domain of all set of real values greater than or equal to 0
This is represented as
x ≥ 0
So, the domain is x ≥ 0

Convert 1/5 to a percentage.
And
Convert 12/100 to a decimal.
Please help.
Answer:
Step-by-step explanation:
to convert the fraction to percentage just multilpy the fraction will 100%
1/5
1/5*100%
100%/5
20%
12/100
3/25
0.12
or in division decimal point goes to the right side
12 can also be written as 12.00 so move the decimal point 2 unit right which becomes .12 .In this case we should move 2 units right because there it is divides by hundred and there are 2 zeros in number hundred.Remember how many units to move right depends upon the number it is divided with.
1/5 is equal to 20% when expressed as a percentage and 12/100 is equal to 0.12 when expressed as a decimal.
To convert 1/5 to a percentage, we can multiply it by 100.
(1/5) * 100 = 20%
Therefore, 1/5 is equal to 20% when expressed as a percentage.
To convert 12/100 to a decimal, we divide the numerator (12) by the denominator (100).
12 ÷ 100 = 0.12
Therefore, 12/100 is equal to 0.12 when expressed as a decimal.
When converting a fraction to a percentage, we multiply the fraction by 100. In this case, 1/5 is equivalent to 0.2 as a decimal. Multiplying it by 100 gives us 20%, expressing the fraction as a percentage.
When converting a fraction to a decimal, we divide the numerator by the denominator. In the case of 12/100, dividing 12 by 100 gives us the decimal representation of 0.12.

Let’s revisit the situation of making a medical supply drop from a helicopter to survivors of a natural disaster. The crate can withstand an impact of 165 ft/sec. If the helicopter has to make the drop at 450ft, then the height of the crate as a function of time is: h(t) = 450 -16t2. The crate will land 5.3 sec after the drop is initiated. Will the crate and medical supplies survive? Show/explain how you know.
You need to compare the instantaneous rates of change.
Answer:
When dropped from 450 feet, the crate and medical supplies will not survive the impact
Step-by-step explanation:
The impact that the crate can withstand when dropped = 165 ft,/sec
The function for the height of the crate at 450 ft. = 450 - 16·t²
The time the crate will land after drop = 5.3 sec
Therefore, we have;
Velocity, V(t) = d(h)/dt
∴ v(t) = d(450 - 16·t²)/dt = -32·t
Given that the time the cate lands after drop, t = 5.3 seconds, we have;
The velocity at 5.3 seconds after drop, v(5.3) = -32 × 5.3 = -169.6
The velocity at 5.3 seconds after drop, v(5.3) = 169.6 ft./sec. (downwards)
Therefore, given that the velocity of the crate at 5.3 seconds (169.6 ft./sec.) is higher than the velocity at which the crate can withstand an impact (165 ft./sec.) the crate and medical supplies will not survive.

(I have already asked the same question twice)
Answer:
[tex]A=2x^2+8x+6\ yards^2[/tex]
Step-by-step explanation:
Step 1, finding the dimensions:
The width of Stacy's room is x, so the length must be 2x. (Her length of the room is two times the width.)
Her sister's room is 2 yards longer and 3 yards wider than Stacy's room. We have:
Length: [tex]2x+2[/tex]
Width: [tex]x+3[/tex]
Great! Let's find the area now.
Step 2, finding the area:
The area of a rectangle is [tex]A=l*w[/tex], where l represents the length of the rectangle, and w represents the width of the rectangle. We already know both, so we can plug it in the equation:
[tex]A=(2x+2)(x+3)[/tex]
We can expand and simplify:
[tex]A=2x^2+2x+6x+6\\A=2x^2+8x+6\ yards^2[/tex]
I hope this helps! Let me know if you have any questions :)
