Which proportion can be used to find the arc length, s, in units?
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = [tex]\frac{150}{360}(2\pi )(42)[/tex]
[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]
[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]
Therefore, Option B will be the answer.

Can someone help me with this please?
Answer:
the function is linear
Step-by-step explanation:
now you figure this out in many ways,
but the easiest is to plot the points on a Cartesian x-y plane, rule a line through the points,if it's in a straight line then its linear if it's a curve its cubic
from the question, after plotting your points.ie (-9,-2),(-5,-7),(-1,-12),(3-17)
we get a straight line pointing downwards.
I hope this is convenient enough

Point D'' (-4,-2) is a vertex of a quadrilateral A'' B'' C'' D''. The original image was rotated 270 degress counterclockwise around the origin and then reflected over the x-axis.
Part A: What are the coordinates of the original image's point D before the composition of transformations?
A. (-4,-2)
B. (-2,-4)
C. (-2,4)
D. (2,-4)
Part B: The original image is quadrilateral ABCD. Point C is on the same y-axis of point D, but five units to the right of point D. If quadrilateral A'' B'' C'' D'' is transformed following the rule (x,y)---> (x-4, y+2), what are the coordinates of point C''?
Answer:
steps below
Step-by-step explanation:
part A: D'' (-4 , -2) (reverse) reflection over x axis -> (-4 , 2)
(-4 , 2) rotated 270 degrees clockwise: -> D (-2 , -4)
Part B: C (-2+5 , -4) = (3 , -4)
C" (3-4 , -4+2) = (-1 , -2)

what is 5 times a number minus 3 is 12 ?
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
Answer:
3
Step-by-step explanation:
x - 3 = 12
12 + 3 = 15
15 - 3 = 12
5( ? ) = 15
15/5
? = 3
5(3) = 15 - 3 = 12

Submarines use sonar systems, which are similar to radar systems, to detect obstacles. Sonar systems use sound to detect objects underwater.
a. You are traveling underwater in a submarine. The sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg. How many meters must the submarine lower to pass under the iceberg?
The submarine must lower at least ____ meters.
Question 2
b. The sonar system then detects a sunken ship 1500 meters ahead, with an angle of elevation of 19∘ to the highest part of the sunken ship. How many meters must the submarine rise to pass over the sunken ship?
The submarine must rise at least ____ meters.
Answer:
a. tan(34)= O/4000 and follow the solving to get the distance it must be lowered
b. (Same idea as a) tan(19)=1500/A and solve to get the distance
The submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.
Given that, the sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg.
What are trigonometric angles?Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.
a) We know that, tan θ = (Perpendicular/Base)
Let the number of meters must the submarine lower to pass under the iceberg be x.
tan θ = x/4000
⇒ tan 34° = x/4000
⇒ 0.6745 = x/4000
⇒ x = 0.6745 × 4000
⇒ x = 2698 meters
b) Let the number of meters must the submarine rise to pass over the sunken ship be y.
tan θ = y/1500
⇒ tan 19° = y/1500
⇒ 0.3443 = y/1500
⇒ y = 0.3443 × 1500
⇒ y = 516.45 meters
Therefore, the submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!
Answer:
Step-by-step explanation:
Normally when you are doing an absolute value question, you do it like this
y = abs(4x - 12) and you write the absolute value equation as
y = 4x - 12 and
y = - 4x + 12
These two are shown in graph27a
to show both wings of the absolute value curve
This is slightly different.
I think you would write this as
y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b

Can you please help me solve for x for this triangle please!!
Answer:
See below, please!
Step-by-step explanation:
Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.
