Answer:
10,000
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000
After five minutes the plane is at 10,000. feet.

a = x -4b = y +3Step-by-step explanation:
You want the transformation rule that describes the translation from R(5, 0) to R'(1, 3).
TranslationThe difference between R' and R is ...
R' -R = (1, 3) -(5, 0) = (1-5, 3-0) = (-4, 3)
The difference between the point (x, y) and the translated point (a, b) is ...

8. You are skiing down a 1,350 meter ski slope at 60 meters per second. Let t
represent your skiing time in seconds and d(t) represent the distance from the
bottom of the ski slope.
The time taken to reach the bottom when the person skies down will be 22.5 seconds.
How to calculate the value?It should be noted that the person is skiing down a 1,350 meter ski slope at 60 meters per second.
There, t represent your skiing time in seconds.
The appropriate expression to illustrate the scenario will be:
1350 - 60t = 0
Therefore, 60t = 1350
t = 1350/60
t = 22.5
The time taken to each the bottom will be 22.5 seconds.

Given the set of information, find a linear equation satisfying the conditions.
X-intercept at (x,y)=(7,0) and y-intercept at (x,y)=(0,2)
Answer:
y = -2/7x + 2
Step-by-step explanation:
y=mx + b is the slope intercept form of a line. The b is the y-intercept. We are given that. The point (0,2) tells us that the line crosses the y intercept at 2.
Now we have to find the slope. The slope is the change in y over the change in y. Given the points (7,0) and (0,2) The y's are 2 and 0 and the x's are 0 and 7. Subtract the y's and subtract the x's.
[tex]\frac{2 - 0}{0 - 7}[/tex] = [tex]\frac{-2}{7}[/tex]
Now we can put in the slope and the y-ntercept
y = mx + b
y = [tex]\frac{-2}{7}[/tex]x + 2

NEED HELP ASAP TODAY IF Can. I have no idea how solve these....
Answer:
62º
Step-by-step explanation:
So this is supplementary angles. Supplementary angles are two or more angles that add up to 180º. This is also vertical angles. Vertical angles are angles across from one another that are congruent(such as the 180º angle and the one up and to the right of it). So if vertical angles are congruent that means that the angle to the right of x is also 118º. And since it is a supplementary angle this is now simple subtraction.
180-118=62.
Hope I could help!
Answer:
62.Step-by-step explanation:
Find the value of x:
118 + x = 180180 - 118 = x180 - 118 = 6262 = xValue x equals 62.A, B & C form the vertices of a triangle, where ∠CAB = 90°.
AB = 10.2 m and AC = 5.6 m.
Evaluate ∠CBA, giving your answer rounded to 3 SF.
The unknown angle of the right triangle is as follows:
∠CBA = 28.8°
How to find the angle of a right triangle?The triangle is a right triangle because one of its angle is equals to 90 degrees.
The angle ∠CBA, can be found using trigonometric rations,
hence,
tan ∅ = opposite / adjacent
where
∅ = ∠CBA
Therefore,
tan ∠CBA = opposite / adjacent
opposite side = 5.6 m
adjacent side = 10.2 m
Hence,
tan ∠CBA = 5.6 / 10.2
tan ∠CBA = 0.54901960784
tan ∠CBA = 0.54901960784
∠CBA = tan⁻¹ 0.54901960784

If angle m∠SOP=(7y-12)° and m∠SOR=(5y+12)°, then the value of y=15 and m∠SOP is equal to 93°.
Given that m∠SOP=(7y-12)° and m∠SOR=(5y+12)°.
We are required to find the value of y and the angle m∠SOP.
We know that sum of all the angles which lie on the straight line is equal to 180°.
And here m∠SOP and m∠SOR both lie on the straight line PR. So,
m∠SOP+m∠SOR=180
7y-12+5y+12=180
12y=180
y=180/12
y=15
We have to use y=15 in m∠SOP=(7y-12)°.
m∠SOP=7*15-12
=105-12

Examine the triangles. Two similar triangles. The first triangle has a side length of 6 inches, which corresponds to the second triangle's side of 18 inches. The first triangle has a side length of 11 inches that corresponds to the missing side on the second triangle. If the triangles are similar, what is the length of the missing side? Note: The triangles may not be drawn to scale.
The length of the missing side of the triangle is 33 inches.
What are similar triangles?Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by ‘~’ symbol.
Let the length of the unknown sides of the second triangle be represented by x.
Given that the two triangles are similar triangles, therefore, the length of the corresponding sides will be in the same ratio. Thus, we can write the ratio of the sides of the triangle as,
6 inches / 18 inches = 11 inches / x
x = (11 inches × 18 inches) / 6 inches
x = 33 inches
Hence, the length of the missing side of the triangle is 33 inches.

Explanation:
The parent function y = |x| has its vertex at the origin (0,0). This is the lowest point on the V shaped graph.
The -2 at the end will shift every point 2 units down. This is because we're subtracting 2 from the y coordinate of each point.

The sides of the triangle are as follows:
a = 43 meters
b = 172 meters
c = 341 meters
Given, we have the perimeter of the triangle as 556 meters.
The sides of the triangle are:
a = x meters
b = 4x meters
c = (8x - 3) meters.
we know that perimeter of the triangle = a + b + c
therefore, a + b+ c = Perimeter
x + 4x + (8x - 3) = 556
x + 4x + 8x - 3 = 556
13x - 3 = 556
13x = 556 + 3
13x = 559
x = 559/13
x = 43
hence we get the value of x as 43.
substitute x value in the sides of the triangle to get the orignal values of the sides.
a = x = 43 meters.
b = 2x = 4 × 43 = 172 meters.
c = 8x - 3 = 8(43) - 3 = 341 meters.
Hence the sides of the triangle are 43 meters , 172 meters and 341 meters.
